With ma own Lil knowledge...

D1,d2,d3 etc depicts the pace at which u wanna go

Eg...the. D1 is as good as gear 1 in a manual car,no matter hw u accelerate it wount excees. The speed limit of gear 1

Same. Applies to d2 and d3

It's just to guage the pace at which u wanna cruise or better still u r on a bad very bad road and u need to go slow,d1 will do and no matter how u accelerate the speed wount exceed the capacity of the d1

Am sure the gurus in the house can explain better

Hi guys,

I was involved in an argument with friends yesterday, over the use of the Driving gears of an automatic gearing car.

Different car products have different automatic gearing system. Mine is a Honda Accord 2006 (Discussion continues) model,and the gear system is pictured below.

It has a 'P-park', 'R-reverse', 'N-neutral' 'D-drive' 'D3', 'D2' and 'D1' gears.

The argument relates to the functions of the 'D', 'D3', 'D2', and 'D1' driving gears respectively, and under what circumstances should each one be used?.

So tech guys in the house, it's time to show off your knowledge.

Merci!!!




Op your car is automanual.
D1 to D4 enables you to transmit on four gears . Its same in a lot of vehicles. Some are telescopic like in some Mercedes tho some older versions like 1999 is same as yours. BMW too had same but now in the contemporary ones you shift to manual first before you can now engage gears telescopic.
Take your car for a ride engage from 1 to 4 like in manual don't worry abt d clutch u can engage while ur leg is on ur accelerator pedal.
Hope this helps

That means you can change gears while the car is in motion, right?

I'm asking, cos you know for Manual cars, you have to 'clutch down' before changing gears.

So for automatic, if I'm moving at, say 120km/hr on 'D', I can just change to, say 'D2' without stepping on the brakes, andd the car will slow down automatically?
if u try change while ur car is ln motion Sorry be ur name

Hello guys. Will make this short. Kinda busy at the moment. The D1, D2 and D3 inscriptions on your gear lever mean that you can engage any one of these three (4 forward gears inclusive of D). The function of this is to enable traction at low speeds. In sandy or very muddy areas, engaging any of the D1, D2 or D3 will restrict the gear from exceeding the respective gearing. Take for instance you select D1, no matter how hard you rev your car engine, your vehicle will never exceed gear 1. This ensures low end traction for sandy terrain or when low end power is needed for towing. If on the othe hand, you select D2, the gear will never exceed second gear no matter how hard you rev the engine. Same applies to D3. If however, D is selected, it allows the gear choose between the 5 available forward gears depending on how hard you rev and the road inclination and conditions. The ECU considers many factors simultaneously and decides the best gear in this case to choose in order to deliver best fuel economy under the prevailing circumstances. Hope this helps. Cheers.



You are good

In many respects "the good old days" seem preferable. For cars automatic gears are a lazy way of driving with the car contolling you, sort of, instead of the other way round.

I think since its automatic, u don't need to change the gear lever while in motion. It will drop back by it self. But you can change it while in motion from d1 to d2. I've witness this in a digital geared car in abuja

I beg to differ on this, engine braking is safer than using the normal brake I tried this on a 1992 honda accord popularly called HALA, at 100km/h, in 5th gear, I down shifted to gear 2 depressed the accelerator and the car slowed down without any jerk or loss of control, done at abk, NNPC road to iyana mortuary express.

You are doing stunt at IYANA mortuary? U de find admission baa?

In other cars it's just D S L I think in this case it's Drive Slow and Learner in that order and it also indicates the speed rate with Drive been the fastest and Learner of course a speed best for learning. The D4 (in some cars) D3, D2 & D1 represent that also but in comparison to a manual that gear one to 4, 4 being the fastest

It's alright.
Before now, I only maintain one gear level 'D' from start to finish grin
so it means can start my car with D1 just like D?

Braking requires friction. Friction causes wear and tear hence yr need to change brake pads at intervals. If engine Braking were safer, everyone would do that instead of changing pads and disks every nw and then. Trust me, each time you're Braking with yr engine, you're damaging something inside it that'll be a big issue when yu come to fix it. Only brake with engine when necessary.

You can start moving yr car with D1. However, it won't remove itself from gear one. This means you get to witness your fuel burning very quickly and your engine overheating.

From my own car manual,
D (Drive)
Use this position for all normal forward driving.
D2 (Second gear)
Use this position for hill climbing or engine braking on downhill grades.
Do not shift into the 2 position at speeds above 74 MPH (118 Km/h). Do not exceed 74 MPH (118 Km/h) in the 2 position.
D1 (Low gear)
Use this position when climbing steep hills slowly or slow driving through deep snow, sand or mud, or for maximum engine brak- ing on steep downhill grades.
Do not shift into the 1 position at speeds above 41 MPH (66 km/h). Do not exceed 41 MPH (66 km/h) in the 1 position.

Bla bla bla. D1 drive in gear one. D2 drive in gear 2. D3 drive in gear 3. D is drive on all gears from 1 to 4 as the case may apply. D =Drive. For broader explanation. D 2 means the car can only drive from gears 1 to 2. D3 means the car can only drive from gear 1 to 3 etc.

Thanks to the OP and the guy that answered the question.
This is a clear indicator to how ignorant Nigerians are. You entered an auto shop to purchase a car and you just pay without asking to know the features in the car you are buying.
Again, most automatic drive car don't have the d1, d2, d3, they just have d. But bro listen, attempting to use these gears will make you hate automatic drives. Don't ever attempt to shift your automatic gear while in motion, you'll just kill that engine.
That luxury in automatic drive isn't the best for you, manual gears have great advantages over automatic gears.

Re: What Are The Functions Of The 'd', 'd3', 'd2' And 'd1' Of Automatic Cars by Gbangbalicious: 12:45pm On Jun 10, 2017
verry simple.......related your manual transmission to the automatic. D1 stands for gear1 in manual no matter how you step on it, it will never leave that gear and it is the strongest of the gears as we know. D2 relates to gear2 in manual no matter how you step on it in the automatic transmission it does not go pass or below and for D3 it is the same. So for the ordinary D, it contains all the gear level and it changes according to the drive conditions, which allows you to cruise you car normally.
