•The rain sensing system will not operate under the
following conditions: when the engine is running and
the gear selector is in the PARK position, or when the
vehicle is started in below freezing temperatures. This
is done to protect the wiper blades from damage. Place
the gear selector in the DRIVE position to allow the
rain sensing feature to operate.
•A customer programmable feature in the Electronic
Vehicle Information Center (EVIC) allows the Rain
Sense feature to be turned off. Refer to “Electronic
Vehicle Information Center (EVIC)” in Section 4 of this
manual.

“TRACTION SYS DISABLED” message will be displayed
in the Electronic Vehicle Information Center (EVIC).
Refer to Section 4 of this manual.
To turn the system back ON, press the switch a second
time, until the “Traction Control Indicator Light” turns
off.When the Traction Control System has been turned off
using the switch, a feature of the system remains active.
This feature functions similar to a limited slip differential
and controls the wheel spin across an axle. If one wheel
on an axle is spinning faster than the other, the system
will apply the brake of the spinning wheel and allow
more engine torque to be applied to the wheel that is not
spinning.
NOTE:
•The “Traction Control Indicator Light” comes on mo-
mentarily each time the ignition switch is turned ON.
This will occur even if you used the switch to turn the
system OFF.
•Each time the ignition is turned ON, the Traction
Control System will be ON even if it was turned OFF
previously.
•The Traction Control System will make buzzing or
clicking sounds when it is active.

ELECTRONIC STABILITY PROGRAM (ESP)— IF
EQUIPPED
WARNING!
ESP (Electronic Stability Program) cannot prevent
the natural laws of physics from acting on the
vehicle, nor can it increase the traction afforded. The
ESP cannot prevent accidents, including those re-
sulting from excessive speed in turns, or hydroplan-
ing. Only a safe, attentive, and skillful driver can
prevent accidents. The capabilities of an ESP-
equipped vehicle must never be exploited in a reck-
less or dangerous manner which could jeopardize
the user’s safety or the safety of others.
ESP (Electronic Stability Program) enhances directional
control and reduces driving wheel spin of the vehicle
under various driving conditions.ESP corrects for over/understeering of the vehicle by
applying brakes to the appropriate wheel. Engine torque
is also limited. The “ESP Indicator Light,” located in the
instrument cluster, starts to flash as soon as the tires lose
traction and the ESP system becomes active.ESP Indicator Light

than the other, the system will apply the brake of the
spinning wheel and allow more engine torque to be
applied to the wheel that is not spinning.
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 off the ESP by pressing the
ESP switch.
With the ESP switched off, the engine torque reduction
and stability features are cancelled. Therefore, the en-
hanced vehicle stability offered by ESP is unavailable.
If the “ESP Indicator Light” begins to flash during
acceleration, 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. When the “ESP
Indicator Light” is illuminated continuously, the ESP is
switched off. To return to the enhanced vehicle stability
offered by ESP, press the ESP switch (the “ESP IndicatorLight” in the instrument cluster goes out). Avoid spin-
ning one drive wheel. This may cause serious damage to
the drive train.
NOTE:
•The “ESP Indicator Light” comes on momentarily each
time the ignition switch is turned ON.
•Each time the ignition is turned ON, the ESP System
will be ON even if it was turned off previously.
•The ESP Control System will make buzzing or clicking
sounds when it is active.
There are two Electronic Vehicle Information Center
(EVIC) messages associated with the Electronic Stability
Control System. Refer to Section 4 of this manual.
ESP System Disabled
This message will be displayed if the ESP System has
been turned off using the switch, or if there is a tempo-
rary condition that will result in partial or no ESP

To Resume Speed
To resume a previously set speed, press and release the
RES·ACCEL button. Resume can be used at any speed
above 25 mph (40 km/h) for 5.7L engines, and 30 mph (48
km/h) for 3.7L/4.7L engines.
To Vary the Speed Setting
When the Speed Control is ON, speed can be increased
by pressing and holding the RES·ACCEL button. When
the button is released, a new set speed will be estab-
lished.
Tapping the RES·ACCEL button once will result in a 2
mph (3 km/h) (3.7L/4.7L Models) or a 1 mph (2 km/h)
(5.7L Models) speed increase. Each time the button is
tapped, speed increases, so tapping the button three
times will increase speed by 6 mph (10 km/h) (3.7L/4.7L
Models) or 3 mph (5 km/h) (5.7L Models), etc.To decrease speed while Speed Control is ON and SET,
press and hold the DECEL button. Release the button
when the desired speed is reached, and the new speed
will be set.
To Accelerate for Passing
Depress the accelerator as you would normally. When the
pedal is released, the vehicle will return to the set speed.
NOTE:When driving uphill, at elevations above 2,000
feet (610 meters), or when the vehicle is heavily loaded
(especially when towing) the vehicle may slow below the
SET speed. If the vehicle speed drops below 25 mph (40
km/h) for 5.7L models, or 30 mph (48 km/h) for 3.7L/
4.7L models, the Speed Control will automatically disen-
gage. If this happens, you can push down on the accel-
erator pedal to maintain the desired speed.
Vehicles may exhibit several 4-3 downshifts under the
above conditions. To reduce the frequency of the down-
shifts and to improve vehicle performance, it is advisable

CAUTION!
Electrical Outlet Use With Engine Off
•Many accessories that can be plugged in draw
power from the vehicle’s battery, even when not
in use (i.e., cellular phones, etc.). Eventually, if
plugged in long enough, the vehicle’s battery will
discharge sufficiently to degrade battery life
and/or prevent engine starting.
•Accessories that draw higher power (i.e., coolers,
vacuum cleaners, lights, etc.) will degrade the
battery even more quickly. Only use these inter-
mittently and with greater caution.
•After the use of high power draw accessories, or
long periods of the vehicle not being started (with
accessories still plugged in), the vehicle must be
driven a sufficient length of time to allow the
generator to recharge the vehicle’s battery.
CUP HOLDERS
In the center console there are two cup holders for the
front seat passengers.
NOTE:The cup holder insert is removable, from the
console, for cleaning. It can be reinstalled with the larger

the wash function. The wash pump will continue to
operate as long as the button is pressed. Upon release, the
wipers will cycle three times before returning to the set
position.If the rear wiper is operating when the ignition is turned
OFF, the wiper will automatically return to the “Park”
position.
If the liftgate flipper glass is open, connection to the rear
window wiper is interrupted preventing activation of the
rear wiper blade. When the liftgate flipper glass is closed,
the rear wiper switch or the ignition switch needs to be
turned OFF and ON to restart the rear wiper.
Adding Washer Fluid
The fluid reservoir for the windshield washers and the
rear window washer is shared. It is located in the front of
the engine compartment on the passenger side and
should be checked for fluid level at regular intervals. Fill
the reservoir with windshield washer solvent (not radia-
tor antifreeze) and operate the system for a few seconds
to flush out the residual water.

INSTRUMENT CLUSTER DESCRIPTION
1. Speedometer
Indicates vehicle speed.
2. Brake Warning Light
The red BRAKE warning light will come on
when the ignition is first turned on, and stay on
briefly as a bulb check. If the bulb does not
come on during starting, have the bulb re-
paired promptly. If the light stays on longer, it may be an
indication that the parking brake has not been released.
If the light remains on when the parking brake is off, it
indicates a possible brake hydraulic system malfunction
or low fluid level. In this case, the light will remain on
until the cause is corrected. If a brake malfunction is
indicated, immediate repair is necessary and continued
operation of the vehicle in this condition is dangerous.3. Turn Signal Indicator Light
The arrow will flash with the exterior turn signal
when the turn signal lever is operated.
If the vehicle electronics sense that the vehicle has
traveled about one mile with the turn signals on, a chime
will sound to alert you to turn the signals off. If either
indicator flashes at a rapid rate, check for a defective
outside light bulb.
4. High Beam Indicator Light
Indicates that headlights are on high beam.
5. Malfunction Indicator Light
This light is part of an onboard diagnostic system
called OBD that monitors engine and automatic
transmission control systems. The light will illu-
minate when the key is in the ON position before engine
start. If the bulb does not come on when turning the key
from OFF to ON, have the condition checked promptly.
164 UNDERSTANDING YOUR INSTRUMENT PANEL

Certain conditions such as a loose or missing gas cap,
poor fuel quality, etc. may illuminate the light after
engine start. The vehicle should be serviced if the light
stays on through several of your typical driving cycles. In
most situations the vehicle will drive normally and will
not require towing.
The Malfunction Indicator Light flashes to alert you to
serious conditions that could lead to immediate loss of
power or severe catalytic converter damage. The vehicle
should be serviced as soon as possible if this occurs. (See
page 313 for more information.)
6. Airbag Warning Light
This light turns on and remains on for 6 to 8
seconds as a bulb check when the ignition
switch is first turned ON. If the light is not on
during starting, stays on, or turns on while
driving, have the system inspected by an authorized
dealer as soon as possible.7. Anti-Lock Brake Warning Light
This light monitors the Anti-Lock Brake System.
The light will turn on when the ignition switch is
turned to the ON position and may stay on for as long as
four seconds.
If the ABS light remains on or turns on while driving, it
indicates that the Anti-Lock portion of the brake system
is not functioning and that service is required. However,
the conventional brake system will continue to operate
normally if the BRAKE warning light is not on.
If the ABS light is on, the brake system should be serviced
as soon as possible to restore the benefits of Anti-Lock
brakes. If the ABS light does not turn on when the
Ignition switch is turned to the ON position, have the
light inspected by an authorized dealer.
