4 LOW to 4 HI
With the vehicle at speeds of 0 to 3 mph (0 to 5 km/h),
key ON or engine running, shift the transmission into N
(Neutral), and raise the transfer case T-handle. The “4WDLOW Indicator Lamp” in the instrument cluster will flash
and go out when the shift is complete. Release the
T-handle.
NOTE:If shift conditions/interlocks are not met, or a
transfer case motor temperature protection condition
exists, a “CHECK SHIFT PROCEDURES” message will
flash from the EVIC (Electronic Vehicle Information Cen-
ter). Refer to “Electronic Vehicle Information Center
(EVIC)” in Section 4 of this manual. (See page 184 for
more information.)
NOTE:Shifting into or out of 4WD LOW is possible
with the vehicle completely stopped, however difficulty
may occur due to the mating clutch teeth not being
properly aligned. Several attempts may be required for
clutch teeth alignment and shift completion to occur. The
preferred method is with the vehicle rolling 0 to 3 mph (0
to 5 km/h). If the vehicle is moving faster than 3 mph (5
km/h), the transfer case will not allow the shift.

268 STARTING AND OPERATING

WARNING!
•Always fully apply the parking brake when leav-
ing your vehicle, or it may roll and cause damage
or injury. Also, be certain to leave the transmis-
sion in P (Park). Failure to do so may allow the
vehicle to roll and cause damage or injury.
•Leaving children in a vehicle unattended is dan-
gerous for a number of reasons. A child or others
could be injured. Children should be warned not
to touch the parking brake or the gear selector
lever. Don’t leave the keys in the ignition. A child
could operate power windows, other controls, or
move the vehicle.
•Be sure the parking brake is fully disengaged
before driving, failure to do so can lead to brake
problems due to excessive heating of the rear
brakes.
When parking on a hill, turn the front wheels toward the
curb on a downhill grade and away from the curb on an
uphill grade.
The parking brake should always be applied whenever
the driver is not in the vehicle.
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.
STARTING AND OPERATING 275

A tire pressure monitoring sensor is located in the spare
wheel if the vehicle is equipped with a matching full size
spare wheel and tire assembly. The matching full size spare
tire can be used in place of any of the four road tires.
The “Tire Pressure Monitoring Telltale Light” will
illuminate in the instrument cluster, and an au-
dible chime will be activated when one or more of
the four active road tire pressures are low. The audible
chime will sound once every ignition cycle for each
condition that it detects. Should this occur, you should
stop as soon as possible, check the inflation pressure of
each tire on your vehicle, and inflate each tire to the
vehicle’s recommended cold tire pressure. The system
will automatically update and the “Tire Pressure Moni-
toring Light” will extinguish once the updated tire pres-
sures have been received. The vehicle may need to be
driven for up to 10 minutes above 15 mph (24 km/h) to
receive this information. A low spare tire will not cause
the “Tire Pressure Monitoring Telltale Light” to illumi-
nate or the chime to sound.The “Tire Pressure Monitoring Telltale Light” will flash
on and off for 60 seconds, and an audible chime will
sound when a system fault is detected. The flash cycle
will repeat every ten minutes, without an audible chime,
until the fault condition no longer exists. If the ignition
key is cycled, this sequence will repeat, providing the
system fault still exists.
NOTE:If your vehicle is equipped with a matching full
size spare tire, it has a tire pressure monitoring sensor,
and can be monitored by the Tire Pressure Monitoring
System (TPMS). In the event that the matching full size
spare tire is swapped with a low pressure road tire, the
next ignition key cycle will still show the “Tire Pressure
Monitoring Telltale Light” to be ON, and a chime to
sound. Driving the vehicle for up to 10 minutes above 15
mph (24 km/h) will turn OFF the “Tire Pressure Moni-
toring Telltale Light” as long as the spare tire or any other
road tire(s) are not below the low pressure warning
threshold.

NOTE:If your vehicle is equipped with a non-matching
full size spare tire, it does not have a tire pressure
monitoring sensor. Therefore, it will not be monitored by
the Tire Pressure Monitor System (TPMS). In the event
that the non-matching full size spare tire is swapped with
a low pressure road tire, each ignition key cycle will still
show the “Tire Pressure Monitoring Telltale Light” to be
ON, and a chime to sound. After the original road tire has
been properly repaired and put back onto the vehicle in
place of the non-matching full size spare tire, the TPMS
will update automatically, and the “Tire Pressure Moni-
toring Telltale Light” will be OFF as long as none of the
road tires are below the low pressure warning threshold.
The vehicle may need to be driven for up to 10 minutes
above 15 mph (24 km/h) to receive this information.CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures have
been established for the tire size equipped on your
vehicle. Undesirable system operation or sensor
damage may result when using replacement equip-
ment that is not of the same size, type, and/or style.
After-market 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.
300 STARTING AND OPERATING

The EVIC will display the “SERVICE TIRE PRESS. SYS-
TEM” message for 3 seconds. This text message is then
followed by a graphic, with “- -“ displayed for the pressure
value(s) indicating which of the Tire Pressure Monitoring
Sensor(s) is not being received. Refer to “Electronic Vehicle
Information Center (EVIC)” in Section 4 of this manual.
NOTE:Your system can be set to display pressure units
in PSI, kPa, or BAR.If the ignition key is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault
no longer exists, the “Tire Pressure Monitoring Telltale
Light” will no longer flash, theSERVICE TIRE PRESS.
SYSTEMtext message will no longer display, and a
pressure value will be displayed instead of dashes.
NOTE:If your vehicle is equipped with a matching full
size spare tire, it has a tire pressure monitoring sensor,
and can be monitored by the Tire Pressure Monitoring
System (TPMS). In the event that the matching full size
spare tire is swapped with a low pressure road tire, the
next ignition key cycle will still show the “Tire Pressure
Monitoring Telltale Light” to be ON, a chime to sound, a
Low Pressure message to appear in the EVIC, and the
graphic display will still show the low tire pressure value
flashing. Driving the vehicle for up to 10 minutes above
15 mph (24 km/h) will turn OFF the “Tire Pressure
Monitoring Telltale Light” as long as the matching full
size spare tire or any other road tire(s) are not below the
304 STARTING AND OPERATING

low pressure warning threshold. The EVIC will display a
“Spare Low Pressure” text message, and the graphic
display will show a new tire pressure value in place of
the flashing low tire pressure value.
NOTE:If your vehicle is equipped with a non-matching
full size spare tire, it does not have a tire pressure
monitoring sensor. Therefore, it will not be monitored by
the Tire Pressure Monitor System (TPMS). In the event
that the non-matching full size spare tire is swapped with
a low pressure road tire, every ignition key cycle will still
show the “Tire Pressure Monitoring Telltale Light” to be
ON, a chime to sound, a Low Pressure message to appear
in the EVIC, and the graphic display will still show the
low tire pressure value flashing. After the original road
tire has been properly repaired and put back onto the
vehicle in place of the non-matching full size spare tire,
the TPMS will update the graphic display on the EVIC
with a new tire pressure value instead of the flashing low
tire pressure value, and the “Tire Pressure MonitoringTelltale Light” will be OFF as long as none of the road
tire(s) are below the low pressure warning threshold. The
vehicle may need to be driven for up to 10 minutes above
15 mph (24 km/h) to receive this information.
