Chevrolet 2010 Impala Automobile User Manual


 
Notice: Shifting out of P (Park) or N (Neutral) with
the engine running at high speed may damage the
transmission. The repairs would not be covered by
the vehicle warranty. Be sure the engine is not
running at high speed when shifting the vehicle.
D (Drive) : This position is for normal driving.
It provides the best fuel economy. If you need more
power for passing, and you are:
.
Going less than 35 mph (55 km/h), push the
accelerator pedal about halfway down.
.
Going about 35 mph (55 km/h) or more, push the
accelerator pedal all the way down.
The transmission will shift down to the next gear
and the vehicle will have more power.
Downshifting the transmission in slippery road
conditions could result in skidding, see Skidding
under Loss of Control on page 511.
Notice: Driving the vehicle if you notice that it is
moving slowly or not shifting gears as you increase
speed may damage the transmission. Have the
vehicle serviced right away. You can drive in
2 (Second) when you are driving less than 35 mph
(55 km/h) and D (Drive) for higher speeds until then.
3 (Third): This position is also used for normal driving.
However, it reduces vehicle speed more than D (Drive)
without using the brakes. You might choose 3 (Third)
instead of D (Drive) when driving on hilly, winding roads,
when towing a trailer, so there is less shifting between
gears and when going down a steep hill.
2 (Second): This position reduces vehicle speed
even more than 3 (Third) without using the brakes.
You can use 2 (Second) on hills. It can help control
vehicle speed as you go down steep mountain roads.
You would also want to use the brakes off and on.
Notice: Driving in 2 (Second) for more than 25 miles
(40 km) or at speeds over 55 mph (90 km/h) may
damage the transmission. Also, shifting into
2 (Second) at speeds above 65 mph (105 km/h)
can cause damage. Drive in 3 (Third) or D (Drive)
instead of 2 (Second).
1 (First): This position reduces vehicle speed
even more than 2 (Second) without using the brakes.
You can use it on very steep hills, or in deep snow or
mud. If the shift lever is in 1 (First) while the vehicle is
moving forward, the transmission will not shift into first
gear until the vehicle is going slowly enough.
Notice: Spinning the tires or holding the vehicle in
one place on a hill using only the accelerator pedal
may damage the transmission. The repair will not be
covered by the vehicle warranty. If you are stuck, do
not spin the tires. When stopping on a hill, use the
brakes to hold the vehicle in place.
