of reasons, including the installation of replacement or
alternate tires or wheels on the vehicle that prevent the
TPMS from functioning properly. Always check the
TPMS malfunction telltale after replacing one or more
tires or wheels on your vehicle, to ensure that the
replacement or alternate tires and wheels allow the TPMS
to continue to function properly.
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system opera-
tion or sensor damage may result when using re-
placement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Do not use tire sealant from a can or
balance beads if your vehicle is equipped with a
TPMS, as damage to the sensors may result.NOTE:
The TPMS telltale is also accompanied by a “Low
Tire” message in the odometer (Base Cluster), or in the
Electronic Vehicle Information Center (EVIC) screen in-
dicating “Low Tire” for EVIC enabled clusters.

Audio/Phone Information And Sub-menu Information
Whenever there are sub-menus available, the position
within the sub-menu is shown here.
The main display area will normally display the main
menu or the screens of a selected feature of the main
menu. The main display area also displays “pop up” messages that consist of approximately 60 possible warn-
ing or information messages. These pop up messages fall
into several categories:
•
Five Second Stored Messages
When the appropriate conditions occur, this type of
message takes control of the main display area for five
seconds and then returns to the previous screen. Most of
the messages of this type are then stored (as long as the
condition that activated it remains active) and can be
reviewed from the “Messages” main menu item. As long
as there is a stored message, an “i” will be displayed in
the EVIC’s compass/outside temp line. Examples of this
message type are “Right Front Turn Signal Lamp Out”
and “Low Tire Pressure”.
• Unstored Messages
This message type is displayed indefinitely or until the
condition that activated the message is cleared. Examples

as there is a stored message, an “i” will be displayed in
the EVIC’s compass/outside temp line. Examples of this
message type are “Right Front Turn Signal Lamp Out”
and “Low Tire Pressure”.
•Unstored Messages
This message type is displayed indefinitely or until the
condition that activated the message is cleared. Examples
of this message type are “Turn Signal On” (if a turn signal
is left on) and “Lights On” (if driver leaves the vehicle).
• Unstored Messages Until RUN
These messages deal primarily with the Remote Start
feature. This message type is displayed until the ignition
is in the RUN state. Examples of this message type are
“Remote Start Aborted - Door Ajar” and “Press Brake
Pedal and Push Button to Start”. •
Five Second Unstored Messages
When the appropriate conditions occur, this type of
message takes control of the main display area for five
seconds and then returns to the previous screen. An
example of this message type is “Automatic High Beams
On”.
EVIC Amber Telltales
This area will show reconfigurable amber caution tell-
tales. These telltales include:
• Low Fuel Telltale
When the fuel level reaches approximately 3.0 gal
(11.0 L) this light will turn on, and remain on until
fuel is added.

STARTING AND OPERATING 291
Proper operation of four-wheel drive vehicles depends
on tires of equal size, type and circumference on each
wheel. Any difference will adversely affect shifting and
can cause damage to the drivetrain.
NOTE:Do not attempt to make a shift while only the
front or rear wheels are spinning. The front and rear
driveshaft speeds must be equal for the shift to take
place. Shifting while only the front or rear wheels are
spinning can cause damage to the transfer case.
Because four-wheel drive provides improved traction,
there is a tendency to exceed safe turning and stopping
speeds. Do not go faster than road conditions permit.
NOTE: Delayed shifts out of four-wheel drive may be
experienced due to uneven tire wear, low or uneven tire
pressures, excessive vehicle loading, or cold tempera-
tures.WARNING!
You or others could be injured or killed if you leave
the vehicle unattended with the transfer case in the
NEUTRAL position without first fully engaging the
parking brake. The transfer case NEUTRAL position
disengages both the front and rear drive shafts from
the powertrain and will allow the vehicle to move
regardless of the transmission position. The parking
brake should always be applied when the driver is
not in the vehicle.
For additional information on the appropriate use of each
transfer case mode position, see the information below:

the control knob back to the current position, wait five
seconds, and retry selection. To find the shift require-
ments, refer to theShifting Procedure for your transfer
case, located in this section.
The “SVC 4WD Warning Light” monitors the electronic
shift four-wheel drive system. If this light remains on
after engine start up or illuminates during driving, it
means that the four-wheel drive system is not function-
ing properly and that service is required.
WARNING!
Always engage the parking brake when powering
down the vehicle if the “SVC 4WD Warning Light” is
illuminated. Not engaging the parking brake may
allow the vehicle to roll, which may cause personal
injury. NOTE:
Do not attempt to make a shift while only the
front or rear wheels are spinning, as this can cause
damage to driveline components.
When operating your vehicle in 4WD LOW, the engine
speed is approximately three times that of the 2WD or
4WD LOCK positions at a given road speed. Take care
not to overspeed the engine and do not exceed 25 mph
(40 km/h).

WARNING!(Continued)
•Unequal tire pressures from one side of the vehicle
to the other can cause the vehicle to drift to the
right or left.
• Always drive with each tire inflated to the recom-
mended cold tire inflation pressure.
Economy
Improper inflation pressures can cause uneven wear
patterns to develop across the tire tread. These abnormal
wear patterns will reduce tread life resulting in a need for
earlier tire replacement. Under-inflation also increases
tire rolling resistance resulting in higher fuel consump-
tion.
Ride Comfort And Vehicle Stability
Proper tire inflation contributes to a comfortable ride.
Over-inflation produces a jarring and uncomfortable
ride. Both under-inflation and over-inflation affect the stability of the vehicle and can produce a feeling of
sluggish response or over responsiveness in the steering.
NOTE:
•
Unequal tire pressures from side to side may cause
erratic and unpredictable steering response.
• Unequal tire pressure from side to side may cause the
vehicle to drift left or right.
Tire Inflation Pressures
The proper cold tire inflation pressure is listed on the
driver’s side B-Pillar or rear edge of the driver’s side
door.
At least once a month:
• Check and adjust tire pressure with a good quality
pocket-type pressure gauge. Do not make a visual

STARTING AND OPERATING 357
Tire Pressures For High Speed Operation
The manufacturer advocates driving at safe speeds and
within posted speed limits. Where speed limits or condi-
tions are such that the vehicle can be driven at high
speeds, maintaining correct tire inflation pressure is very
important. Increased tire pressure and reduced vehicle
loading may be required for high-speed vehicle opera-
tion. Refer to your authorized tire dealer or original
equipment vehicle dealer for recommended safe operat-
ing speeds, loading and cold tire inflation pressures.
WARNING!
High speed driving with your vehicle under maxi-
mum load is dangerous. The added strain on your
tires could cause them to fail. You could have a
serious collision. Do not drive a vehicle loaded to the
maximum capacity at continuous speeds above
75 mph (120 km/h).
Radial Ply Tires
WARNING!
Combining radial ply tires with other types of tires
on your vehicle will cause your vehicle to handle
poorly. The instability could cause a collision. Al-
ways use radial ply tires in sets of four. Never
combine them with other types of tires.
Tire Repair
If your tire becomes damaged, it may be repaired if it
meets the following criteria:
• The tire has not been driven on when flat.
• The damage is only on the tread section of your tire
(sidewall damage is not repairable).
• The puncture is no greater than ¼ (6 mm).
