panel down. Do not use the cargo tie down hooks
located on the floor behind the seat.Finally, tighten all
three straps as you push the child restraint rearward and
downward into the seat, removing slack in the straps
according to the child restraint manufacturer’s instruc-
tions.
WARNING!
Improper installation of a child restraint to the
LATCH anchorages can lead to failure of an infant or
child restraint. The child could be badly injured or
killed. Follow the manufacturer’s directions exactly
when installing an infant or child restraint.
Installing Child Restraints Using The Vehicle Seat
Belts
The seat belts in the passenger seating positions are
equipped with an Automatic Locking Retractor (ALR) to secure a Child Restraint System (CRS). These types of
seat belts are designed to keep the lap portion of the seat
belt tight around the child restraint so that it is not
necessary to use a locking clip. The ALR will make a
ratcheting noise if you extract the entire belt from the
retractor and then allow the belt to retract into the
retractor. For additional information on ALR, refer to
“Automatic Locking Mode” description under “Seat
Belts in Passenger Seating Positions” section. The chart
below defines the seating positions with an Automatic
Locking Retractor (ALR).

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 89

Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver ’s responsibility to
maintain correct tire pressure, even if under-inflation has
not reached the level to trigger illumination of the TPMS
low tire pressure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system is not
operating properly. The TPMS malfunction indicator is
combined with the low tire pressure telltale. When the
system detects a malfunction, the telltale will flash for
approximately one minute and then remain continuously
illuminated. This sequence will continue upon subse-
quent vehicle start-ups as long as the malfunction exists.
When the malfunction indicator is illuminated, the sys-
tem may not be able to detect or signal low tire pressure
as intended. TPMS malfunctions may occur for a variety
of reasons, including the installation of replacement or
alternate tires or wheels on the vehicle that prevent the
TPMS from functioning properly. Always check theTPMS 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.4

the messages of this type are then stored (as long as the
condition that activated it remains active) and can be
reviewed from the Messagesmain menu item. As long
as there is a stored message, an iwill 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 areTurn 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 andPress Brake

Rating and Password Setup
The Rating and Password settings work together to
control the types of DVDs that your family watches. Most
DVD-Video discs have a rating (from 1 to 8) assigned to them where lower numbers are designated for all audi-
ences and higher numbers are designated for more adult
audiences.
When a DVD-Video disc is loaded, its rating is compared
to the setting in the DVD player. If the rating of the disc
is higher than the setting in the player, a Password screen
is displayed. In order to watch the disc, the rear passen-
ger must enter the correct password using the password
entry method described below.
To play all discs without requiring a password, set the
DVD player ’s rating to Level 8. Setting the rating to Level
1 always requires the password to play any DVD disc.
Not all DVD discs encode a Rating, so it is still possible
that discs designed for adult audiences can still play
without requiring a password.
The default rating is Level 8 (play all discs without a
password) and the default password is 0000.

ABS and Traction Control, provides resistance to any
wheel that is slipping to allow additional torque transfer
to wheels with traction.
NOTE:The Quadra-Trac I system is not appropriate
for conditions where 4WD LOW range is recommended.
Refer to “Off-Road Driving Tips” in “Starting and Oper-
ating” for further information.
Quadra-Trac II Operating Instructions/
Precautions – If Equipped
The Quadra-Trac II transfer case is fully automatic in the
normal driving 4WD AUTO mode. The Quadra-Trac II 
transfer case provides three mode positions:
•4WD HI
•NEUTRAL
•4WD LOW
This transfer case is fully automatic in the 4WD HI mode. When additional traction is required, the 4WD LOW
position can be used to lock the front and rear driveshafts
together and force the front and rear wheels to rotate at
the same speed. The 4WD LOW position is intended for
loose, slippery road surfaces only. Driving in the 4WD
LOW position on dry, hard-surfaced roads may cause
increased tire wear and damage to driveline components.
When operating your vehicle in 4WD LOW, the engine
speed is approximately three times that of the 4WD HI
position at a given road speed. Take care not to overspeed
the engine and do not exceed 25 mph (40 km/h).
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
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.

WARNING! (Continued)
•Unequal tire pressures from one side of the ve-
hicle 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
consumption.
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 thestability of the vehicle and can produce a feeling of
sluggish response or over responsiveness in the steering.
Unequal tire pressures can cause erratic and unpredict-
able 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.
The pressure should be checked and adjusted, as well as
inspected for signs of tire wear or visible damage, at least
once a month. Use a good quality pocket-type gauge to
check tire pressure. Do not make a visual judgement
when determining proper inflation. Radial tires may look
properly inflated even when they are under-inflated.
488 STARTING AND OPERATING

Tire Pressures For High Speed Operation
The manufacturer advocates driving at safe speeds
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 original equipment or an authorized tire
dealer for recommended safe operating speeds, loading
and cold tire inflation pressures.
WARNING!
High speed driving with your vehicle at or above
maximum 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 tires in sets of four. Never combine
them with other types of tires.
Cuts and punctures in radial tires are repairable only in
the tread area because of sidewall flexing. Consult your
authorized dealer for radial tire repairs.
Spare Tire Matching Original Equipped Tire And
Wheel – If Equipped
Your vehicle may be equivalent with a spare tire and
wheel in look and function as the original equipment tire
and wheel found on the front or rear axle of your vehicle.
