AUTOMATIC OVERDRIVE (D):This position is for
normal driving. 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 all the way down.
The transmission will shift down to a lower gear
and have more power.
Notice:Spinning the tires or holding the vehicle in
one place on a hill using only the accelerator
pedal may damage the transmission. If you are
stuck, do not spin the tires. When stopping on a hill,
use the brakes to hold the vehicle in place.
FOURTH (4):This position is also used for normal
driving. However, it offers more power and lower fuel
economy than AUTOMATIC OVERDRIVE (D).
Here are examples for using FOURTH (4) instead of
AUTOMATIC OVERDRIVE (D):
When driving on hilly, winding roads.
When going down a steep hill.
This position may also offer improved trailer towing
performance in certain driving conditions.
Driver Shift Control (DSC)
Notice:If you drive your vehicle at high rpms
without upshifting while using Driver Shift
Control (DSC), you could damage your vehicle.
Always upshift when necessary while using DSC.
Your automatic transmission has a Driver Shift
Control (DSC) feature that allows you to change
gears similar to a manual transmission. To use the
DSC feature:
1. Slide the shift lever over from AUTOMATIC
OVERDRIVE (D) to the right into the DSC area.
The DIC will display which mode the transmission
is in. SeeDriver Information Center (DIC) on
page 3-73.
If you do not move the shift lever forward or
rearward, the vehicle will be in sport mode. While
driving in sport mode, the transmission may remain
in a gear longer than it would in normal driving
mode based on braking, throttle input and vehicle
lateral acceleration.
2. Press the shift lever forward to upshift or rearward
to downshift.
The odometer on the instrument panel cluster will
change to show the requested gear range when moving
the shift lever forward or rearward.

Running the Engine While Parked
It is better not to park with the engine running. But if you
ever have to, here are some things to know.
{CAUTION:
Idling the engine with the climate control
system off could allow dangerous exhaust into
your vehicle. See the earlier caution under
Engine Exhaust on page 2-33.
Also, idling in a closed-in place can let deadly
carbon monoxide (CO) into your vehicle even if
the climate control fan is at the highest setting.
One place this can happen is a garage.
Exhaust — with CO — can come in easily.
NEVER park in a garage with the engine
running.
Another closed-in place can be a blizzard.
SeeWinter Driving on page 4-25.
{CAUTION:
It can be dangerous to get out of your vehicle
if the shift lever is not fully in PARK (P) with
the parking brake rmly set. Your vehicle can
roll. Do not leave your vehicle when the engine
is running unless you have to. If you have left
the engine running, the vehicle can move
suddenly. You or others could be injured. To
be sure your vehicle will not move, even when
you are on fairly level ground, always set your
parking brake after you move the shift lever to
PARK (P).
Follow the proper steps to be sure your vehicle will
not move. SeeShifting Into Park (P) on page 2-30.
