Pontiac 2007 G6 Owner's Manual page 131

DRIVE (D): This position is for normal driving. It
provides the best fuel economy for your vehicle. If
you need more power for passing, and you are:
•
Going less than 35 mph (55 km/h), push
your accelerator pedal about halfway down.
•
Going about 35 mph (55 km/h) or more, push
the accelerator all the way down.
You will shift down to the next gear and have
more power.
Downshifting the transaxle in slippery road
conditions could result in skidding, see "Skidding"
under Loss of Control on page 271.
Notice: If your vehicle seems to accelerate
slowly or not shift gears when you go faster,
and you continue to drive your vehicle that way,
you could damage the transaxle. Have your
vehicle serviced right away. You can drive in
LOW (L) when you are driving less than 35 mph
(55 km/h) and DRIVE (D) for higher speeds
until then.
THIRD (3): This position, available on the SE
model, is also used for normal driving. However,
it reduces vehicle speed more than DRIVE (D)
without using your brakes. Here are some times
you might choose THIRD (3) instead of DRIVE (D):
•
When driving on hilly, winding roads.
•
When towing a trailer, so there is less shifting
between gears.
•
When going down a steep hill.
LOW (L): This position, available on the SE model,
reduces vehicle speed more than THIRD (3)
without using your brakes. You can use LOW (L) on
hills. It can help control your speed as you go down
steep mountain roads, but then you would also
want to use your brakes off and on.
