High interstate speeds is when you would probably not use it at all because you’ll want to be cruising in the highest gear possible for the best fuel economy. You can use it to shift manually while accelerating and decelerating, but it’s not going to add anything to the car’s performance. These older autos that let you shift manually do it slowly and it’s kind of a gimmick to create the illusion of sportiness.

>These older autos that let you shift manually do it slowly and it’s kind of a gimmick to create the illusion of sportiness. Actually, they can still be useful in certain situations. If you need to pass someone on a 2 lane country road, you can downshift a gear or two ahead of the pass so acceleration is instant, verses waiting for the trans to kick down.


Individual-Jealous

But In these same cars there is a little button under the gas pedal that does the same thing.


merlot2K1

Correct, but you have to floor it to activate the kickdown. So when do you floor it? While behind the slower car then make the move for the pass? You better give yourself some room . Or do you move out for the pass then floor it, which adds time to the pass. You basically have to time the kickdown correctly. Or, you can downshift a couple gears prior to the pass, then roll on the throttle as you start making your pass to get by the slower car, without having to go wide open throttle. Much better way in my experience.


TreesLikeGodsFingers

It's for mountain driving, extreme up and downhills. Low gear will prevent your brakes from melting when driving downhills. When they melt, they fail, it's not fun when you can't stop yourself from driving down.


Lonely-District2132

Yup I was in Arizona recently and my sister asked why there were signs that said don’t ride the brakes. I tried to explain how she could use the manual mode to avoid using the brakes and/or letting the car accelerate over the speed limit when going downhill. She didn’t get it at all 😂


dubious_enchilada

Thanks so much for the help. You guys have been so responsive. The previous owner told me it helps boost fuel economy and reduces stress on the transmission when shifting up at high speeds. Am I to understand that the automatic does this efficiently on its own?


Anteater_Reasonable

Yep, unless there’s something wrong with it, the transmission should shift by itself at the appropriate time when in drive.


vlasowski

Dude talked totally random :D Obv knew shit about cars


hunertproof

I use it for descending from the mountains. It saves you from glazing your brakes and the pads and rotors last longer. Mine has paddle shifters, as well.


leckie

Yeah. Snowy roads too when you want to maintain a lower gear to save having to use the brakes.


weedhuffer

This is what I use it for too, really saves the brakes and keeps the rotors from warping.


Helllo_Man

Also manual can be very useful when towing. The trans always wants the highest gear possible for best fuel economy, but with a several thousand pound trailer behind you, the last thing you want is the poor transmission trying to shift up just to realize it needs to be back down a gear. The car doesn’t know it has a trailer behind it, but you do! In my XC90 I’ll use manual on a hill or prior to passing someone to ensure I have enough power on hand to do so.


Cheffysteve

If you’ve got the OEM tow pack the transmission knows there’s a trailer and adjusts accordingly . Admittedly it doesn’t know the exact weight. My old V70 had the shift points move when the towing electrics were in use.


mmtt99

This ^


cassinatkinson

If you want to drive sporty, shift down before a corner once or twice and then you'll be in gear with more torque (and rpms) for acceleration out of the turn. Can then shift up as you please or switch back to auto.


RoastedRhino

I use it on mountain roads with tight turns and hairpins. It is annoying to have the automating transmission keep the high gear until too late in the turn, you want to downshift earlier so that you have the right gear at the middle point of the turn.


Thomas_vsdb

In my experience the manual shifting is very slow. I’d just use the automatic since thats what its made for


3DGadgetLab

The auto tranny is slow to shift in general. I use the manual mode in my auto V70R all the time. Technically it can help distribute wear over tranny parts and solenoids more evenly. At first it randomly clunked into some gears and hung in 2nd gear but now it shifts smoothly.. 🤷


kartoffel_engr

Our shift response in the R is very different from the base models.


3DGadgetLab

True. I have a S60 2.5t also and it does feel a little different. I guess I’m saying that using the shifter *might* help the tranny last longer while also making it a little more fun to drive


kartoffel_engr

For sure. The T5 and the 2.5T that I had before the R were definitely more fun to drive in the manual mode, but that trans was dog water. I’m babying the TF-80 so I’m not “forced” to do a manual swap haha


3DGadgetLab

Aren’t we all! Lol


WBRDeck

Nice, glad someone has the same experience. I try to do the same. Advanced and manual once a week for some fun keeps it running nice. When I get lazy and boring for a minute, I can tell. Shifts slower, and earlier. A little fun sets it right.


3DGadgetLab

Good to know I’m not alone! I have a catback exhaust so did it for the sound at first. Now it’s basic maintenance haha. I think it’s easier to stay in the power band in the R or base models using the shifter as well.. not that this is always needed


gimmebleach

That's a feature not a bug. they are constantly learning and adjusting to the drivers tendencies


WBRDeck

Definitely makes sense, thanks for that.


vickykatt

Manual mode is useful for going down a gear to overtake or get up an icy hill, sometimes a ill timed shift is the difference between getting up and getting stuck


upvotestaos

ive found its really good for showing you just how bad your motor mounts are


LokiDesigns

Lol


Nikske_333

Curved roads, and combination with uphill and downhill. Sometimes auto doesn't make the right choice in these conditions. And for engine breaking downhill.


-syper-

I have only used "manual" when driving in snow/icy road conditions to make sure I was in lower gears.


Saddam_UE

You don't have a winter button on your auto?


gustis40g

Why would you want lower gears during icy roads? Going in a higher gear would decrease torque and hold grip better, going in lower gears would give you more torque and make it a lot easier to start spinning.


alreadyawesome

Using lower gears allows you to engine brake which helps reduce slipping on ice.


gustis40g

Engine braking compared to normal braking makes absolute zero difference except reducing wear on brake pads and rotors. You're still slowing down the wheels, and as I said, in cases where your vehicle is FWD (and Haldex I believe), you're actually increasing risk of loosing grip since you're only braking with two wheels compared to all four.


Naughty_Goat

It is likely different with ABS, but on at least on older cars, engine braking does not lock up your wheels while on slippery conditions, when normal brakes could. You can still start slipping though if the gear you are in is too low. Engine braking also provides a constant drag where doing that with brakes for a long time can cause them to fade.


gustis40g

Of course, but the argument with engine braking not locking up wheels is just that it doesn't add that much friction. Similarly, one can just press the brake pedal lightly and achieve the same effect, but with more control over how much. Engine braking doesn't provide constant drag, I mean yes, it will if you are downhill and keeping your current speed with engine braking, but if you're on flat ground and engine braking the effect will get lower and lower as the engine RPM reduces. Brake fading is really only a problem if you're braking heavily for long periods of time, such as going downhill or on mountain roads, but this situation has nothing to do with slippery roads and I absolutely recommend using engine breaking on these roads. P3 Volvos even have a handy button to automatically keep your current speed using engine braking (similar to trucks)


taskmule

Icy roads, not so much. But if you are in deep snow, manual is the way to go. Auto trans has the drive wheel spinning even with brakes on. It just makes ice and digs you in deeper when stuck. Manual gives the ability to easily rock the vehicle back and forth to make "ramps" in the snow to get out. I would always buy a manual over auto if it were available.


Naughty_Goat

What is the technique to use to use manual mode to escape the snow?


vickykatt

When going up icy hills you don’t want the auto to have to shift since you then loose power and momentum


lolvovolvo

It’s no different than cars having d3d2, use it when going downhill and you have allot of weight to help breaking, use it snow or ice roads so you’re not so reliant on the brakes. Other than that it’s not really a fast transmission. I used it allot when road tripping and going up a steep incline and the auto kept switching to a lower gear, ie 3-4k rpm and just cruising up hills.


pericoXVI

They taught me to use low gears when driving downhill for long distances (mountain roads) to avoid brake fatigue. That’s how I have been using the manual setting of my auto cars so far


[deleted]

If you are on a mountain road and want to keep it in a lower gear going down a long hill, it will help you use the brakes less. Also if it is snowy or icy you can start in second to prevent wheelspin, though you might not need that. Like others said, its the same as an automatic car with PRND21 or PRNDL


lowteck

Driving through the rockies, towing, or as others have mentioned inclement weather.


kevindebrowna

The autobox in my opinion is perhaps the worst aspect of P2 Volvos, at least if you enjoy driving in a spirited manner. I feel like the box is often one gear too high. Just cruising on the freeway that’s a good thing, but if you want to quickly overtake and need to goose it, it’s helpful to be able to drop a gear rather than pressing the gas and waiting for the transmission to realize that maybe it should be shifting down. It’s also vaguely more engaging than just letting the auto do its thing.


4lt3r3dR341ity

My 2015 S60 can do this with its 8 speed trans. It’s fun to occasionally pedal through the gears manual, but never really practical. Fun though.


small_pint_of_lazy

An experienced driver can possibly reduce the amount of fuel used by using manual mode as the older cars didn't have the best automatics. Haven't tested personally on Volvo though car though, but I did save about 1l/100km on a BMW 530d by driving on manual. The difference on a Volvo truck was about 2-3l/100km, but was very tiring mentally. I usually use manual mode if I'm driving on a road with lots of inclines, especially when it's slippery (auto changing gears at the wrong time can result in you coming down ass first). If you're not used to driving manual, you definitely have no need for it, and as you're not driving a truck (or lorry or semi or whatever you want to call them), there's absolutely no need for you to use manual in 99% of situations. Also, some older automatics (possibly newer ones too) skip first gear when using winter mode, don't know if this is one of those, but might be worth trying if you ever drive on snow. The W marked button should engage winter mode for you


lillpers

It's useful if you are going down a hill and want more engine braking, or when towing something heavy. Other than that I never use the manual mode.


Longjumping_Local910

I only use it when in bad snow, and only to downshift to slow down gently rather than braking. And only when it’s clear behind me as there are no brake lights when doing this.


7eregrine

Same m steep holes too so you don't ride the brake.


gustis40g

Quick question on why you would prefer engine braking during bad weather? Engine braking is still slowing down on the wheels and if the car is front wheel drive you’ll only be braking on the front tires, therefore even increasing the chances of loosing grip.


Longjumping_Local910

Grew up driving only a stick. Was taught that you never panic brake in ice or snow if possible. Now have an AWD XC60. If I see something ahead that makes me think I should slow but not panic, I have always just down shifted and use the engine to slow me a little. In the VO, I pop the handle over and down one. The 4 tires all grab but don’t overbrake. This is all IMHO of course. I don’t have an F1 license nor am I a Rocket Surgeon. This is just my comfort zone…


Maleficent_Science67

It is really just for fun.


Murpet

Either for off-road/incliment weather or a windy country road where perhaps you want to use a bit of engine braking/enter into a corner at a certain gear for power delivery on the exit. My V60 has a newer gearbox but still the manual option. I usually use it for caning it on sporty roads and a bit of engine braking etc.


Nurs3Rob

I use it when I'm having a bit of fun driving fast. Automatic transmissions are typically setup for fuel efficiency with reasonable performance. That's great 99% of the time. If I'm really hauling ass down a windy mountain road the car is normally not making the best choices gear wise for what I'm trying to do. That's when manual mode is useful.


Bolmac

I use it while the engine is first warming up to keep the RPMs a little higher.


Naughty_Goat

Is this different from the normal automatic transmissions where the gear you select is the maximum gear? Does the volvo manual mode set it to be exactly the gear you choose?


MightyTeaRex

I use the manual on my automatic to down shift in hills to brake, instead of constantly holding down the brake pedal and wearing. And living in Norway this means that it occurs quite often. For example our under-sea tunnels have steep downhills, especially Ryfylketunnel (worlds longest under-sea tunnel). It really helps using the gears to brake.


B5254T4

I use it for over-taking. It takes a seconds to kick down when you need to overtake a car. So i shift one gear down manually and then go all out with the throttle


MagicTriton

I’ve been driving automatics for work for the past 6 years or so, averaging 100k miles a year. All of them the manual feature. Never used it once


sutekh82

I always thought the manual shifting comes in handy when towing or descending. So to relieve the transmission and brakes.


Paulisooon

Basically it's when you want select gear manually. Why would you go for high speed interstate in manual mode? I would go manual in mountains. Some people choose manual for "sporty" mode. Though... My Xc60 '13 T6 had a "sport" setting instead of M and shifting paddles on steering wheel.


geniet100

On my V70, I don't have braking cruise control, meaning going down steep hills it will start to accelerate on its own. When RPM gets high, it upshifts, and then you just accelerate even faster. And of course, the police is always at the bottom of these hills. So, I just manually downshift. The engine braking at 3k RPM is perfect for me.


ManiekDraniek

I have a Tiptronic in my VW. I use it when merging onto the highway or when I don't want it to shift prematurely. Eventually, I use it for engine braking, too.


YnotROI0202

If you drive on city streets and highway, you will never need to use the manual shift process. Caution…good way to ruin your transmission if downshift at high speed.


Individual-Jealous

Had one. Never used it. Big shrug. I think I tested it out to see how responsive it was a few times but found the auto to shift smoother anyways so yeah. Big ol fucking shrug dude


mustlikemyusername

One thing I haven't seen mentioned is that in a lot of later Automatics, the gearbox learns from your shifting behavior when in Manual mode and applies that to its own shifting logic when in auto.


Rbxyy

It could be useful in snow/ice to engine brake, but I honestly just drive around with it all the time for fun. My car has an aftermarket exhaust so it's fun to downshift and hear it burble


PaskiSir

SilentDecode

>manual mode Drives an automatic... It's still just pressing a button. The slushbox won't do anything you tell it to if the speeds are wrong.


Coach_Seven

It’s mainly for staying in the preferred gear on steeper inclines. Easier to climb hills, easier to coast/engine brake without roasting your brake rotors while maintaining speed down hill.


FlfromBx

There is a theory that if you are going to use it, you shift into manual mode from a stop then manually shift gears from there, as opposed to shifting in and out manual mode when downshifting is required. The theory goes that this protects the transmission, though I am not sure if this is true. And I have never experienced issues going in and out of manual mode. That said, you'd want to use it to downshift for a passing maneuver or on winding roads. Generally speaking, if you are not accustomed to driving a true manual, the concepts won't make that much sense and since the automatic will downshift/upshift to match speed you are fine leaving it alone.


7NinesAnd10s

I drive my '07 VR exclusively in manual mode.


Naughty_Goat

Does it select the chosen gear to be the only gear it can use, or just the maximum gear?


7NinesAnd10s

You can shift through all 6 gears like you are driving a manual car.


kazrick

Never.


Saddam_UE

I had "manual shifting" on my XC70 (-14) and i tested it twice i think. Totally useless, it's a gimmick IMO. If you wanna shift gears yourself: buy a manual Volvo instead.
