e
OD (Automatic Overdrive). This position is for normal driving. If you need
more power for passing, and you're:
- Going less than about 35 mph (56 km/h), push your accelerator
pedal about halfway down.
- Going about 35 mph (56 km/h) or more, push the accelerator all the
way down. You'll shift down to the next gear and have more power.
OD should not be used when towing a trailer, carrying a heavy load,
driving on steep hills, or for off-road driving. Select D (third gear) when
operating the vehicle under any of these conditions.
D (Third Gear). This is like OD, but you never go into Overdrive. You
should use D when towing a trailer, carrying a heavy load, driving on
steeps hills, or for off-road driving.
2 (Second Gear). This position gives you more power but lower fuel
economy. You can use 2 (Second Gear) 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.
If you have a
4.3L
engine (Codes Z and W) and if you manually select
2,
the transmission will drive in second gear. You may use this feature
for reducing torque
to
the rear wheels when you are trying to start your
vehicle from a stop on slippery road surfaces.
1 (First Gear). This position gives you even more power (but lower fuel
economy) than 2. You can use
it
on very steep hills, or in deep snow or
mud. If the selector lever is put in 1, the transmission won't shift into
first gear until the vehicle is going slowly enough.
