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) or
a cinching latch plate 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 ALRwill 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) or a cinching latch plate.

84 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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

position locks the front driveshaft and rear driveshaft
together and forces the front and rear wheels to rotate at
the same speed.
Use the transfer case NEUTRAL position for recreational
towing only. Refer to “Recreational Towing” in “Starting
and Operating” for further information.
CAUTION!
•Do not attempt to make a shift while only the front
wheels or rear wheels are spinning. The MP1522
Command-Tractransfer case is not equipped
with a synchronizer and therefore the speed of the
front driveshaft and rear driveshaft must be equal
for the shift to take place. Shifting while only the
front wheels or rear wheels are spinning can cause
damage to the transfer case.
(Continued)
CAUTION! (Continued)
•The 4WD LOCK position and 4WD LOW position
are intended for loose or slippery road surfaces
only. Driving in these positions on dry hard-
surfaced roads may cause increased tire wear and
damage to the driveline components.
•When operating your vehicle in 4WD LOW, the
engine speed is approximately three times that of
the 2WD position or 4WD LOCK position at a
given road speed. Take care not to over-speed the
engine and do not exceed 25 mph (40 km/h).
•Proper operation of four-wheel drive vehicles de-
pends on tires of equal size, type, and circumfer-
ence on each wheel. Any difference in tire size can
cause damage to the transfer case. Tire rotation
schedule should be followed to balance tire wear.
322 STARTING AND OPERATING

This transfer case is intended to be driven in either the
two-wheel drive position (2WD) or the four-wheel drive
Auto position (4WD AUTO) for normal street and high-
way conditions such as dry hard-surfaced roads.
For added capability when traversing steep grades,
rough terrain, or extremely poor traction surfaces, select
the transfer case 4WD LOW position. This position locks
the front driveshaft and rear driveshaft together and
forces the front and rear wheels to rotate at the same
speed while multiplying engine torque.
Use the transfer case NEUTRAL position for recreational
towing only. Refer to “Recreational Towing” in “Starting
and Operating” for further information.CAUTION!
•The 4WD LOW position is intended for loose or
slippery road surfaces only. Driving in this posi-
tion on dry hard-surfaced roads may cause in-
creased tire wear and damage to the driveline
components.
•When operating your vehicle in 4WD LOW, the
engine speed is approximately three times that of
the 2WD position or 4WD AUTO position at a
given road speed. Take care not to over-speed the
engine and do not exceed 25 mph (40 km/h).
•Proper operation of four-wheel drive vehicles de-
pends on tires of equal size, type, and circumfer-
ence on each wheel. Any difference in tire size can
cause damage to the transfer case. Tire rotation
schedule should be followed to balance tire wear.
328 STARTING AND OPERATING

ANTI-LOCK BRAKE SYSTEM
The Anti-Lock Brake System (ABS) is designed to aid the
driver in maintaining vehicle control under adverse
braking conditions. The system operates with a separate
computer to modulate hydraulic pressure, to prevent
wheel lock-up and help avoid skidding on slippery
surfaces.
All vehicle wheels and tires must be the same size and
type, and tires must be properly inflated, to produce
accurate signals for the computer.
WARNING!
Significant over or under-inflation of tires or mixing
sizes of tires or wheels on the vehicle can lead to loss
of braking effectiveness.The ABS conducts a low-speed self-test at about 12 mph
(20 km/h). If you have your foot lightly on the brake
while this test is occurring, you may feel slight pedal
movement. The movement can be more apparent on ice
and snow. This is normal.
The ABS pump motor runs during the self-test at 12 mph
(20 km/h) and during an ABS stop. The pump motor
makes a low humming noise during operation, which is
normal.
WARNING!
•Pumping of the Anti-Lock Brakes will diminish
their effectiveness and may lead to a collision.
Pumping makes the stopping distance longer. Just
press firmly on your brake pedal when you need
to slow down or stop.

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.5
STARTING AND OPERATING 367

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.
This spare tire may be used in the tire rotation for your
5
STARTING AND OPERATING 369

vehicle. If your vehicle has this option refer to an
authorized tire dealer for the recommended tire rotation
pattern.
If your vehicle is not equipped with an original equip-
ment tire and wheel as a spare, a non-matching tempo-
rary emergency use spare may be equipped with your
vehicle. Temporary use spares are engineered to be used
only with your vehicle. Your vehicle may be equipped
with one of the following types of non-matching tempo-
rary use spares; compact, full size, or limited-use. Do not
install more than one non-matching temporary use spare
tire/wheel on the vehicle at any given time.
CAUTION!
Because of the reduced ground clearance, do not take
your vehicle through an automatic car wash with a
compact, full size or limited-use temporary spare
installed. Damage to the vehicle may result.
Compact Spare Tire – If Equipped
The compact spare is for temporary emergency use only.
You can identify if your vehicle is equipped with a
compact spare by looking at the spare tire description on
the Tire and Loading Information Placard located on the
driver ’s side door opening or on the sidewall of the tire.
Compact spare tire descriptions begin with the letter “T”
or “S” preceding the size designation. Example: T145/
80D18 103M.
T, S = Temporary Spare Tire
Since this tire has limited tread life the original equip-
ment tire should be repaired (or replaced) and reinstalled
on your vehicle at the first opportunity.
Do not install a wheel cover or attempt to mount a
conventional tire on the compact spare wheel, since the
wheel is designed specifically for the compact spare tire.
Do not install more than one compact spare tire and
wheel on the vehicle at any given time.
