period of time. Drive mode, RWD or AWD, is displayed
momentarily in the Electronic Vehicle Information Center
(EVIC) in the gage area of the vehicle display when the
transmission is first shifted into gear, and if the drive
mode changes during vehicle operation.
NOTE:If the “SERVICE AWD SYSTEM” warning mes-
sage appears after engine start up, or during driving, it
means that the AWD system is not functioning properly
and that service is required. Refer to “Electronic Vehicle
Information Center (EVIC)” in “Understanding Your
Instrument Panel” for further information.
CAUTION!
All wheels must have the same size and type tires.
Unequal tire sizes must not be used. Unequal tire
size may cause failure of the front differential and/or
the transfer case.
DRIVING ON SLIPPERY SURFACES
Acceleration
Rapid acceleration on snow covered, wet, or other slip-
pery surfaces may cause the driving wheels to pull
erratically to the right or left. This phenomenon occurs
when there is a difference in the surface traction under
the rear (driving) wheels.
WARNING!
Rapid acceleration on slippery surfaces is dangerous.
Unequal traction can cause sudden pulling of the rear
wheels. You could lose control of the vehicle and
possibly have a collision. Accelerate slowly and
carefully whenever there is likely to be poor traction
(ice, snow, wet mud, loose sand, etc.).

STARTING AND OPERATING 331

If the “SERVICE POWER STEERING SYSTEM”
message and a flashing icon are displayed on
the EVIC screen, it indicates that the vehicle
needs to be taken to the dealer for service. It is
likely the vehicle has lost power steering assistance. Refer
to “Electronic Vehicle Information Center (EVIC)” in
“Understanding Your Instrument Panel” for further in-
formation.
If the “POWER STEERING SYSTEM OVER TEMP” mes-
sage and an icon are displayed on the EVIC screen, it
indicates that extreme steering maneuvers may have
occurred, which caused an over temperature condition in
the power steering system. You will lose power steering
assistance momentarily until the over temperature con-
dition no longer exists. Once driving conditions are safe,
then pull over and let vehicle idle for a few moments
until the light turns off. Refer to “Electronic Vehicle
Information Center (EVIC)” in “Understanding Your
Instrument Panel” for further information. NOTE:
•Even if power steering assistance is no longer opera-
tional, it is still possible to steer the vehicle. Under
these conditions there will be a substantial increase in
steering effort, especially at very low vehicle speeds
and during parking maneuvers.
•If the condition persists, see your authorized dealer for
service.
MULTI-DISPLACEMENT SYSTEM (MDS)
(IF EQUIPPED) — 5.7L ENGINE ONLY
This feature offers improved fuel economy by shutting
off four of the engine’s eight cylinders during light load
and cruise conditions. The system is automatic with no
driver inputs or additional driving skills required.
NOTE:
The MDS system may take some time to return
to full functionality after a battery disconnect.

STARTING AND OPERATING 335

PARKING BRAKE
Before leaving the vehicle, make sure that the parking
brake is fully applied and place the shift lever in the
PARK position.
The foot operated parking brake is located below the
lower left corner of the instrument panel. To apply the
park brake, firmly push the park brake pedal fully. To
release the parking brake, press the park brake pedal a
second time and let your foot up as you feel the brake
disengage.When the parking brake is applied with the ignition
switch in the ON position, the “Brake Warning Light” in
the instrument cluster will illuminate.

336 STARTING AND OPERATING

ESC Operating Modes
The ESC system has two available operating modes:
ESC On
This is the normal operating mode for the ESC. When-
ever the vehicle is started, the ESC system will be in this
mode. This mode should be used for most driving
conditions. The ESC should only be turned OFF for
specific reasons as noted in the following paragraphs.
Partial Off
The “Partial Off” mode is intended for times when a
more spirited driving experience is desired. It is also
intended for driving in deep snow, sand, or gravel. This
mode disables the TCS portion of the ESC and raises the
threshold for ESC activation, which allows for more
wheel spin than what ESC normally allows.The “ESC Off” switch is located on the switch bank in the
center of the instrument panel. To enter the “Partial Off”
mode, momentarily press the “ESC Off” switch and the
“ESC Activation/Malfunction Indicator Light” will illu-
minate. To turn the ESC on again, momentarily press the
“ESC Off” switch and the “ESC Activation/Malfunction
Indicator Light” will turn off.
NOTE:
To improve the vehicle’s traction when driving
with snow chains, or when starting off in deep snow,
sand, or gravel, it may be desirable to switch to the
“Partial Off” mode by momentarily pressing the “ESC
Off” switch. Once the situation requiring “Partial Off”
mode is overcome, turn the ESC on again by momen-
tarily pressing the “ESC Off” switch. This may be done
while the vehicle is in motion.

WARNING! (Continued)
•HSA is not a parking brake. If you stop the vehicle
on a hill without putting the transmission in
PARK and using the parking brake, it will roll
down the hill and could cause a collision with
another vehicle or object. Always remember to use
the parking brake while parking on a hill, and that
the driver is responsible for braking the vehicle.
HSA Off
If you wish to turn off the HSA system, it can be done
using the Customer Programmable Features in the Elec-
tronic Vehicle Information Center (EVIC). Refer to “Elec-
tronic Vehicle Information Center (EVIC)” in “Under-
standing Your Instrument Panel” for further information.
Ready Alert Braking
Ready Alert Braking may reduce the time required to
reach full braking during emergency braking situations.It anticipates when an emergency braking situation may
occur by monitoring how fast the throttle is released by
the driver. When the throttle is released very quickly,
Ready Alert Braking applies a small amount of brake
pressure. This brake pressure will not be noticed by the
driver. The brake system uses this brake pressure to allow
a fast brake response if the driver applies the brakes.
Rain Brake Support
Rain Brake Support may improve braking performance
in wet conditions. It will periodically apply a small
amount of brake pressure to remove any water buildup
on the front brake rotors. It only functions when the
windshield wipers are in the LO or HI mode, it does not
function in the intermittent mode. When Rain Brake
Support is active, there is no notification to the driver and
no driver interaction is required.
346 STARTING AND OPERATING

HAZARD WARNING FLASHERS
The Hazard Warning flasher switch is located in the
center of the instrument panel between the center air
outlets.Press the switch to turn on the Hazard Warning
flashers. When the switch is activated, all direc-
tional turn signals will flash on and off to warn
oncoming traffic of an emergency. Press the switch a
second time to turn off the Hazard Warning flashers.
This is an emergency warning system and it should not
be used when the vehicle is in motion. Use it when your
vehicle is disabled and it is creating a safety hazard for
other motorists.
When you must leave the vehicle to seek assistance, the
Hazard Warning flashers will continue to operate even
though the ignition is placed in the OFF position. NOTE:
With extended use the Hazard Warning flashers
may wear down your battery.
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the
potential for overheating by taking the appropriate ac-
tion.
•On the highways — slow down.
•In city traffic — while stopped, place the transmission
in NEUTRAL, but do not increase the engine idle
speed.
NOTE: There are steps that you can take to slow down
an impending overheat condition:
•If your air conditioner (A/C) is on, turn it off. The A/C
system adds heat to the engine cooling system and
turning the A/C off can help remove this heat.
408 WHAT TO DO IN EMERGENCIES

Your authorized dealer will reset the oil change indicator
message after completing the scheduled oil change. If a
scheduled oil change is performed by someone other
than your authorized dealer, the message can be reset by
referring to the steps described under “Electronic Vehicle
Information Center (EVIC)/Oil Change Required” in
“Understanding Your Instrument Panel” or under “In-
strument Cluster Description/Odometer/Trip Odom-
eter” in “Understanding Your Instrument Panel” for
further information.At Each Stop For Fuel
•Check the engine oil level. Refer to “Maintenance
Procedures/Engine Oil” in “Maintaining Your Ve-
hicle” for further information.
•Check the windshield washer solvent and add if
required.
