While going uphill, use the D1, D2, or D3 gears to maintain higher RPMs and give your vehicle more climbing power and speed. Note: Most automatic vehicles have at least a D1 and D2 gear, while some models also have a D3 gear.Jul 26, 2016
Low gear is very useful when you encounter a steep hill or extended downgrade. That’s because your brakes work hard when descending, maintaining your speed and fighting gravity as you drive. In regular conditions, this prolonged stress can cause your brakes to overheat – which can even lead to failure!
This is a great gear for everyday terrain when you’re cruising along on a flat road or on undulating terrain. You want some resistance, but not too much. If the road goes up and down a bit, you’ll probably flick between the rear gears to cater for changes.
The most likely issue is a clogged fuel filter. … When the fuel filter is clogged, the fuel pump has to work much harder, resulting in a far less efficient drive. This means you can’t get the power you need if you’re trying to accelerate when overtaking or going uphill.
3 – Third gear
These gears may be used when going up or down hills and on road conditions like slush, loose gravel, snow, sand or ice, where you need more power but less speed. The vehicle’s engine will not start in this gear.
“S” is for sport. If you’re driving on twisty country roads and want to keep the RPM up as you wind through corners, the “S” position is where you want to be. In “S”, the transmission holds lower gears longer for more power as you come out of the curves.
tboult said: There is a risk of shifting from D to L while driving.. soon you’ll be in Sport and doing it all the time like you are downshifting in a sports car and you S.O. may make silly comments.. But it will be too late as you’ll be addicted.
Use Lower Gears to Go Downhill
If your vehicle has an automatic transmission, use “L” or “2.” However, if you do need to brake frequently, pull over if you start to smell the brakes burning.
Explanation: The engine will need more power to pull the vehicle up the hill. When approaching a steep hill you should select a lower gear to help maintain your speed. You should do this without hesitation, so that you don’t lose too much speed before engaging the lower gear.
When driving uphill the engine has to work harder. This means you will have to accelerate for longer in the lower gears and make upward gear changes promptly so that the car doesn’t slow excessively when you push the clutch pedal down.
Bicycles have multiple gears so that it’s easier to go up hills, and so you can go faster on level ground.
In other words, 46 to 49 on the chainring and 16 to 18 on the cassette will meet most people’s needs. If you don’t want to stray out too far, a 46/17 to 42/17 are good gear ratios for smaller and occasional hills. These gear rates are considered a good middle ground that can be used in flat and hilly areas.

Driving uphill can be tough, especially if the slope is steep. In particular, if you drive a manual, you might have problems with stalling or rolling backwards. Shifting to a lower gear is the key to delivering power to your wheels and controlling your speed.
Driving in three will not damage your car, in fact in most cases its better for your car you will just get less MPG. Be wary that while driving in 3 on the highway isnt bad, second or first could be harmful depending on your speed.
Is it OK to start in second gear? … Most automatic transmissions have a W (Winter) mode that starts off in second gear to help prevent the tires from spinning on slick pavement. So, for most drivers, starting in second gear is really no issue.
Low gear, also known as first gear, is a mode on both manual transmissions and automatic vehicles, which restricts the amount of fuel injected into the engine. This mode helps to boost torque while decreasing engine speeds.
S is Sport mode. It will make the throttle sharper and keep the rpms higher. Imagine a normal auto holding gears longer before shifts. L is for low gear. It would be used when going down a steep grade.
4D means 4 door, 2D means 2 door. 4WD and 2WD are the terms you are looking for. If you car has 4WD, there should be a place near the shifter telling you how to get it into 4WD…otherwise you have a 2WD.
Use D3 to provide engine braking when going down a steep hill. D3 can also keep the transmission from cycling between third and fourth gears in stop-and-go driving. For faster acceleration when in D3 or D4, you can get the transmission to automatically downshift by pushing the accelerator pedal to the floor.
You should always check your owner’s manual to find out what the speed limit is for low gear, as exceeding the limit can cause damage to both the engine and the transmission. Towing with the automatic transmission set in low will keep the engine torque even and consistent, providing the power you need.
Vehicles going uphill should be given precedence. While parking your car on a positive (uphill) gradient, use the parking brake and shift the lever into the first gear position. On a negative gradient (downhill) shift the lever to the reverse position.
Turn the front wheels towards the kerb and place the vehicle in the reverse gear, this will prevent the vehicle from rolling into traffic if the breaks become disengaged avoiding the highway.
Most automatic transmissions also allow you to select one or more positions past the PRND options. … For example, in a four-speed, selecting 3 would allow the automatic transmission to shift among 1st gear, 2nd gear and 3rd gear, but 4th gear would be locked out, accessible only by selecting Drive.
Which TWO apply when driving up steep hills? Explanation: The engine will need more power to pull the vehicle up the hill. When approaching a steep hill you should select a lower gear to help maintain your speed.
Lower gears are like a longer lever: They provide more mechanical advantage. Higher gears are like a shorter lever: They provide less mechanical advantage.
