Notice:Shifting to R (Reverse) while the vehicle is
moving forward could damage the transmission.
The repairs would not be covered by the vehicle
warranty. Shift to R (Reverse) only after the vehicle
is stopped.
R (Reverse): Use this gear to back up.
At low vehicle speeds, you can also use R (Reverse)
to rock your vehicle back and forth to get out of snow,
ice, or sand without damaging the transmission. See If
Your Vehicle is Stuck in Sand, Mud, Ice, or Snow
on
page 5‑22for additional information.
N (Neutral): In this position, the engine does not
connect with the wheels. To restart the engine when the
vehicle is already moving, use N (Neutral) only. You can
also use N (Neutral) when the vehicle is being towed.
{WARNING:
Shifting into a drive gear while the engine is
running at high speed is dangerous. Unless your
foot is firmly on the brake pedal, the vehicle could
move very rapidly. You could lose control and hit
people or objects. Do not shift into a drive gear
while the engine is running at high speed. 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 all the way down.
The transmission will shift down to a lower gear
and have more power.
Downshifting the transmission in slippery road
conditions could result in skidding, see “Skidding”under
Loss of Control on page 5‑14.

Driver Shift Control (DSC)
Notice:If you drive the vehicle at a high rpm
without upshifting while using Driver Shift Control
(DSC), you could damage the vehicle. Always
upshift when necessary while using DSC.
Driver Shift Control (DSC) allows you shift an automatic
transmission similar to a manual transmission. To use
the DSC feature:
1. Move the shift lever to the right from D (Drive) into the DSC area.
When in DSC mode, the
sport symbol will appear
in the Driver Information
Center (DIC).
The vehicle will remain in sport mode if the
shift lever is not moved. Sport mode will shift
automatically but remain in a gear longer then it
would in normal driving mode based on braking
and acceleration. 2. Press the shift lever forward to upshift or rearward
to downshift.
When using the DSC
mode, the number
displayed on the Driver
Information Center (DIC)
indicates the gear that the
transmission is in. See
Driver Information Center
(DIC)
on page 4‑69for
more information on
the DIC.
When starting the vehicle from a stopped condition, only
1 (First) and 2 (Second) gear may be used.
While using the DSC feature the vehicle will have firmer
shifting and increased performance. You can use this
for sport driving or when climbing/descending hills to
stay in gear longer or to down shift for more power or
engine braking.
The transmission will only allow you to shift into
gears appropriate for the vehicle speed and engine
Revolutions Per Minute (RPM). The transmission will
not automatically shift to the next higher gear if the
engine RPM is too high.

If shifting is prevented for any reason, the selected gear
will flash multiple times, indicating that the transmission
has not shifted gears.
The transmission will allow you to shift to the gear
selected and will automatically downshift when the
vehicle comes to a stop. This will allow for more power
during take-off and passing.
Parking Brake
The parking brake pedal
is located on the lower
portion of the instrument
panel to the left of the
steering wheel.
The vehicle has a push-to-release parking brake pedal.
To set the parking brake, hold the brake pedal down,
then push the parking brake pedal down. If the ignition is on, the brake system warning light on
the instrument panel cluster should come on. If it does
not, you need to have the vehicle serviced. See
Brake
System Warning Light
on page 4‑58for more
information.
To release the parking brake, hold the brake pedal
down, then push the parking brake pedal. When you
release the park brake pedal, the parking brake
releases.
Notice: Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Make sure
that the parking brake is fully released and the
brake warning light is off before driving.
A warning chime will sound if the parking brake is set,
the ignition is on and the vehicle begins to move. To
stop the chime, fully release the parking brake.

Shifting Into Park
{WARNING:
It can be dangerous to get out of the vehicle if the
shift lever is not fully in P (Park) with the parking
brake firmly set. The vehicle can roll. If you have
left the engine running, the vehicle can move
suddenly. You or others could be injured. To be
sure the vehicle will not move, even when you are
on fairly level ground, use the steps that follow.
If you are pulling a trailer, seeTowing a Trailer
on
page 5‑31
.
To shift into P (Park), use the following steps: 1. Hold the brake pedal down.
2. Move the shift lever into P (Park) by pressing the button on the front of the shift lever while pushing

Leaving the Vehicle With the Engine
Running
{WARNING:
It can be dangerous to leave the vehicle with the
engine running. The vehicle could move suddenly
if the shift lever is not fully in P (Park) with the
parking brake firmly set. And, if you leave the
vehicle with the engine running, it could overheat
and even catch fire. You or others could be
injured. Do not leave the vehicle with the engine
running.
If you leave the vehicle with the engine running, the
vehicle must be in P (Park) and the parking brake set.

Torque Lock
Torque lock is when the weight of the vehicle puts too
much force on the parking pawl in the transmission.
This happens when parking on a hill and shifting the
transmission into P (Park) is not done properly and then
it is difficult to shift out of P (Park). To prevent torque
lock, set the parking brake and then shift into P (Park).
To find out how, see“Shifting Into P (Park)” listed
previously.
If torque lock does occur, your vehicle may need to be
pushed uphill by another vehicle to relieve the parking
pawl pressure, so you can shift out of P (Park).
Shifting Out of Park
Shift lock release prevents shifting out of P (Park)
unless the vehicle is running or in Accessory mode and
the brake pedal is applied.
The shift lock release is always functional except in the
case of an uncharged or low voltage (less than 9‐volt)
battery. See Jump Starting
on page 6‑38for more
information. To shift out of P (Park) use the following:
1. Apply the brake pedal.
2. Press the shift lever button.
3. Move the shift lever to the desired position.
If you still are unable to shift out of P (Park): 1. Fully release the shift lever button.
2. While holding down the brake pedal, press the shift lever button again.
3. Move the shift lever to the desired position.
If you still cannot move the shift lever from P (Park),
consult your dealer or a professional towing service.

Compass
Compass Operation
PressOto turn the compass on or off.
When the ignition and the compass feature are on, the
mirror displays the compass heading after a few
seconds.
Compass Calibration
If after few seconds, the display does not show a
compass heading (for example, N for North), there may
be a strong magnetic field interfering with the compass.
Interference can be caused by a magnetic antenna
mount, magnetic note pad holder or a similar magnetic
item. If the letter C should ever appear in the compass
window, the compass may need calibration.
The mirror can be calibrated by driving the vehicle in
circles at 5 mph (8 km/h) or less until the display reads a
direction.
The compass can be placed in calibration mode
manually by pressing and holding
Ountil a C is shown
in the compass display.
Compass Variance
The mirror is set to zone eight. If you do not live in zone
eight or drive out of the area, the compass variance
needs to be changed to the appropriate zone.
To adjust for compass variance:
1. Find the current location and variance zone number on the following zone map.
2. Press and holdOuntil a zone number displays.
