WARNING!
It is dangerous to move the shift lever out of PARK or
NEUTRAL if the engine speed is higher than idle
speed. If your foot is not firmly pressing on the brake
pedal, the vehicle could accelerate quickly forward or
in reverse. You could lose control of the vehicle and
hit someone or something. Only shift into gear when
the engine is idling normally and when your foot is
firmly pressing the brake pedal.
Key Ignition Park Interlock
This vehicle is equipped with a Key Ignition Park Inter-
lock which requires the shift lever to be placed in PARK
prior to rotating the key fob to the LOCK/OFF position.
The key fob can only be removed from the ignition when
the ignition is in the LOCK/OFF position, and once
removed, the shift lever is locked in PARK.
Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmission Shift
Interlock System (BTSI) that holds the shift lever in the
PARK position when the ignition switch is in the LOCK/
OFF position. To move the shift lever out of the PARK
position, the ignition switch must be turned to the
ON/RUN position (engine running or not) and the brake
pedal must be pressed.
Six-Speed Automatic Transmission
The shift lever position display (located in the instrument
panel cluster) indicates the transmission gear range. You
must press the brake pedal to move the shift lever out of
the PARK position (Refer to “Brake/Transmission Shift
Interlock System” in this section). To drive, move the shift
lever from PARK or NEUTRAL to the DRIVE position.
The electronically-controlled transmission provides a
precise shift schedule. The transmission electronics are
self-calibrating; therefore, the first few shifts on a new

WARNING! (Continued)
•It is dangerous to move the shift lever out of PARK
or NEUTRAL if the engine speed is higher than
idle speed. If your foot is not firmly on the brake
pedal, the vehicle could accelerate quickly forward
or in reverse. You could lose control of the vehicle
and hit someone or something. Only shift into
gear when the engine is idling normally and your
foot is firmly pressing the brake pedal.(Continued)
WARNING! (Continued)
•Unintended movement of a vehicle could injure
those in or near the vehicle. As with all vehicles,
you should never exit a vehicle while the engine is
running. Before exiting a vehicle, always apply the
parking brake, shift the transmission into PARK,
and remove the ignition key. Once the key is
removed, the shift lever is locked in the PARK
position, securing the vehicle against unwanted
movement. Furthermore, you should never leave
unattended children inside a vehicle.
•Never leave children alone in a vehicle. Leaving
unattended children in a vehicle is dangerous for a
number of reasons. A child or others could be
seriously or fatally injured. Do not leave the
ignition key in the vehicle. A child could operate
power windows, other controls, or move the
vehicle.

STARTING AND OPERATING 215

CAUTION!
•Before moving the shift lever out of PARK, you
must turn the ignition switch from the LOCK/OFF
position to the ON/RUN position, and also press
the brake pedal. Otherwise, damage to the shift
lever could result.
•DO NOT race the engine when shifting from
PARK or NEUTRAL into another gear range, as
this can damage the drivetrain.
The following indicators should be used to ensure that
you have engaged the shift lever in the PARK position:
•When shifting into PARK, move the shift lever all the
way forward and to the left until it stops and is fully
seated.
•Look at the shift lever position display and verify that
it indicates the PARK position.
•With brake pedal released, verify that the shift lever
will not move out of PARK.
REVERSE
This range is for moving the vehicle backward. Shift into
REVERSE only after the vehicle has come to a complete stop.
NEUTRAL
Use this range when the vehicle is standing for prolonged
periods with the engine running. The engine may be
started in this range. Set the parking brake and shift the
transmission into PARK if you must leave the vehicle.
WARNING!
Do not coast in NEUTRAL and never turn off the
ignition to coast down a hill. These are unsafe
practices that limit your response to changing traffic
or road conditions. You might lose control of the
vehicle and have a collision.
216 STARTING AND OPERATING

PARK, REVERSE, and NEUTRAL will continue to oper-
ate. Limp Home Mode allows the vehicle to be driven to
an authorized dealer for service without damaging the
transmission.
In the event of a momentary problem, the transmission
can be reset to regain all forward gears by performing the
following steps:
1. Stop the vehicle.
2. Shift the transmission into PARK.
3. Turn the ignition switch to the LOCK/OFF position.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is no
longer detected, the transmission will return to normal
operation.NOTE:
Even if the transmission can be reset, we recom-
mend that you visit your authorized dealer at your
earliest possible convenience. Your authorized dealer has
diagnostic equipment to determine if the problem could
recur.
If the transmission cannot be reset, authorized dealer
service is required.
AUTOSTICK — IF EQUIPPED
AutoStickis a driver-interactive feature providing
manual shift control, giving you more control of the
vehicle. AutoStick allows you to maximize engine brak-
ing, eliminate undesirable upshifts and downshifts, and
improve overall vehicle performance. This system can
also provide you with more control during passing, city
driving, cold slippery conditions, mountain driving,
trailer towing, and many other situations.
218 STARTING AND OPERATING

WARNING!
Continued operation with reduced or no power steer-
ing assist could pose a safety risk to yourself and
others. Service should be obtained as soon as pos-
sible.
PARKING BRAKE
Before leaving the vehicle, make sure that the parking
brake is fully applied. Also, be certain to leave manual
transmission in REVERSE or first gear.
The parking brake lever is located in the center console.
To apply the parking brake, pull the lever up as firmly as
possible. To release the parking brake, pull the lever up
slightly, press the center button, then lower the lever
completely.When the parking brake is applied with the ignition
switch in the MAR (ACC/ON/RUN) position, the Brake
Warning Light in the instrument cluster will illuminate.
When parking on a hill, it is important to turn the front
wheels toward the curb on a downhill grade and away

224 STARTING AND OPERATING

from the curb on an uphill grade. The parking brake
should always be applied whenever the driver is not in
the vehicle.
WARNING!
•Never leave children alone in a vehicle, or with
access to an unlocked vehicle.
•Allowing children to be in a vehicle unattended is
dangerous for a number of reasons. A child or
others could be seriously or fatally injured. Chil-
dren should be warned not to touch the parking
brake, brake pedal or the shift lever.
•Do not leave the key fob in or near the vehicle, and
do not leave the ignition in the MAR (ACC/ON/
RUN) position. A child could operate power win-
dows, other controls, or move the vehicle.(Continued)
WARNING! (Continued)
•Be sure the parking brake is fully disengaged
before driving; failure to do so can lead to brake
failure and a collision.
•Always fully apply the parking brake when leav-
ing your vehicle, or it may roll and cause damage
or injury. Also, be certain to leave a manual
transmission in REVERSE or first gear. Failure to
do so may cause the vehicle to roll and cause
damage or injury.
CAUTION!
If the Brake Warning Light remains on with the
parking brake released, a brake system malfunction
is indicated. Have the brake system serviced by an
authorized dealer immediately.

STARTING AND OPERATING 225

BRAKE SYSTEM
In the event power assist is lost for any reason (for
example; repeated brake applications with the engine
off), the brakes will still function. The effort required to
brake the vehicle will be significantly more than that
required with the power system operating.
If either the front or rear hydraulic system loses normal
capability, the remaining system will still function with
some loss of braking effectiveness. This will be evident by
increased pedal travel during application, greater pedal
force required to slow or stop, and activation of the Brake
Warning Light and the ABS Warning Light during brake
use.
Four-Wheel Anti-Lock Brake System (ABS)
The Four-Wheel ABS is designed to aid the driver in
maintaining vehicle control under adverse braking con-
ditions. The system operates with a separate computer tomodulate hydraulic pressure, to prevent wheel lock-up
and to help avoid skidding on slippery surfaces.
The system’s pump motor runs during an ABS stop to
provide regulated hydraulic pressure. The pump motor
makes a low humming noise during operation, which is
normal.
The ABS includes an amber ABS Warning Light. When
the light is illuminated, the ABS is not functioning. The
system reverts to standard non-anti-lock brakes. Turning
the ignition Off and On again may reset the ABS if the
fault detected was only momentary.
228 STARTING AND OPERATING

To turn ESC on again, momentarily press the switch
again. This will restore the normal ESC On mode of
operation.
NOTE:To improve the vehicle’s traction when driving
with snow chains, or starting off in deep snow, sand or
gravel, it may be desirable to switch to the Partial Off
mode by pressing the switch. Once the situation requir-
ing ESC to be switched to the Partial Off mode is
overcome, turn ESC back on by momentarily pressing the
switch. This may be done while the vehicle is in motion.
WARNING!
When in “Partial Off” mode, the TCS portion of ESC
has been disabled and the “ESC Off Indicator Light”
will be illuminated. All other stability features of
ESC function normally. When in “Partial Off” mode,
the enhanced vehicle stability offered by the ESC
system is reduced.
ESC Activation/Malfunction Indicator Light And
ESC OFF Indicator Light
The ESC Activation/Malfunction Indicator
Light in the instrument cluster will come on
when the ignition switch is turned to the MAR
(ACC/ON/RUN) position for four seconds. If
the ESC Activation/Malfunction Indicator Light comes
on continuously with the engine running, a malfunction
has been detected in the ESC system. If this light remains
on after several ignition cycles, and the vehicle has been
driven several miles (kilometers) at speeds greater than
30 mph (48 km/h), see your authorized dealer as soon as
possible to have the problem diagnosed and corrected.
The ESC Activation/Malfunction Indicator Light (located
in the instrument cluster) starts to flash as soon as the
tires lose traction and the ESC system becomes active.
The ESC Activation/Malfunction Indicator Light also
flashes when TCS is active. If the ESC Activation/
5

Malfunction Indicator Light begins to flash during accel-
eration, ease up on the accelerator and apply as little
throttle as possible. Be sure to adapt your speed and
driving to the prevailing road conditions.
NOTE:
•The ESC Activation/Malfunction Indicator Light and
the ESC OFF Indicator Light come on momentarily
each time the ignition switch is turned ON.
•Each time the ignition is turned ON, the ESC system
will be ON even if it was turned off previously.The ESC OFF Indicator Light indicates the
Electronic Stability Control (ESC) is off.

236 STARTING AND OPERATING

•Four Tire Pressure Monitoring Sensors
•Tire Pressure Monitoring Telltale Light
Tire Pressure Monitoring Low Pressure Warnings
The Tire Pressure Monitoring Telltale Light will illumi-
nate in the instrument cluster, an audible chime will be
activated, and the “Check Tire Pressure” text message
will display when one or more of the four active road tire
pressures are low. Should this occur, you should stop as
soon as possible, check the inflation pressure of each tire
on your vehicle, and inflate each tire to the vehicle’s
recommended cold placard pressure value. The system
will automatically update and the Tire Pressure Monitor-
ing Light will extinguish once the updated tire pressures
have been received. The vehicle may need to be driven
for up to 20 minutes above 15 mph (24 km/h) to receive
this information.
Check TPMS Warnings
The Tire Pressure Monitoring Telltale Light will flash on
and off for 75 seconds and remain on solid when a system
fault is detected, and the “Tire Pressure Monitoring
Unavailable” text message will display. If the ignition key
is cycled, this sequence will repeat providing the system
fault still exists. The Tire Pressure Monitoring Telltale
Light will turn off when the fault condition no longer
exists. A system fault can occur with any of the following
scenarios:
1. Jamming due to electronic devices or driving next to
facilities emitting the same radio frequencies as the TPM
sensors.
2. Installing some form of aftermarket window tinting
that affects radio wave signals.
3. Snow or ice around the wheels or wheel housings.
4. Using tire chains on the vehicle.
