Hummer h3 Automobile User Manual


 
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 about 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.
Downshifting the transmission in slippery road conditions
could result in skidding, see “Skidding” under Loss of
Control on page 4-10.
DRIVE (D) can be used when towing a trailer. You may
want to shift the transmission to THIRD (3) or, if
necessary, a lower gear if the transmission shifts too
often under heavy loads and/or hilly conditions.
THIRD (3): This position is also used for normal
driving. However it reduces vehicle speed more than
DRIVE (D) without using your brakes. 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 and when going down
a steep hill.
SECOND (2): This position reduces vehicle speed
even more than THIRD (3) without using your brakes.
You can use SECOND (2) 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.
FIRST (1): This position reduces vehicle speed even
more than SECOND (2) without using your brakes.
You can use it on very steep hills, or in deep snow or
mud. If the shift lever is put in FIRST (1) 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 your warranty. If you are stuck,
do not spin the tires. When stopping on a hill,
use the brakes to hold the vehicle in place.
