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.4WD LOW to 4WD 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
NEUTRAL, and raise the transfer case T-handle. The
“4WD LOW” indicator light 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 Center).
Refer to “Electronic Vehicle Information Center
(EVIC)” in Section 4 of this manual.
•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 prop-
erly 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.
NEUTRAL Shift Procedure
1. Key ON, engine off.
2. Vehicle stopped, with foot on brake.
3. Place transmission into NEUTRAL.
4. Hold down the NEUTRAL “pin” switch (with a pen,
etc.) for four seconds until the LED lamp by the switch
starts to blink indicating shift in progress. The lamp will
stop blinking (stay on solid) when the NEUTRAL shift is
complete. A “4WD SYSTEM IN NEUTRAL” message will
display on the EVIC (Electronic Vehicle Information
Center). Refer to “Electronic Vehicle Information Center
(EVIC)” in Section 4 of this manual.5. Repeat Steps 1 to 4 to shift out of NEUTRAL.
NOTE:If shift conditions/interlocks are not met, a
“CHECK SHIFT PROCEDURES” message will flash from
the EVIC (Electronic Vehicle Information Center). Refer
to “Electronic Vehicle Information Center (EVIC)” in
Section 4 of this manual.

NOTE:The Brake Warning Light indicates only that the
parking brake is applied. It does not indicate the degree
of brake application.
Be sure the parking brake is firmly set when parked and
the shift lever is in the PARK position. When parking on
a hill, you should apply the parking brake before placingthe shift lever in PARK, otherwise the load on the
transmission locking mechanism may make it difficult to
move the shift lever out of PARK.
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 transmission
in PARK. Failure to do so may allow the vehicle to
roll and cause damage or injury.
•Leaving unattended children in a vehicle 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 shift lever. Do
not leave the key in the ignition. A child could
operate power windows, other controls, or move
the vehicle.

The Tire Pressure Monitoring Telltale Light will flash on
and off for 75 seconds, and remain on solid when a
system fault is detected. In addition, a “CHECK TPM
SYSTEM” message will be displayed for 75 seconds when
a system fault is detected, and a chime will sound. If the
ignition key is cycled, this sequence will repeat, provid-
ing the system fault still exists. The Tire Pressure Moni-
toring Telltale Light will turn off when the fault condition
no longer exists. A system fault can occur by any of the
following:
1. Jamming due to electronic devices or driving next to
facilities emitting the same Radio Frequencies as the TPM
sensors.
2. Installing some form of aftermarket window tinting
that affects radio wave signals.
3. Lots of snow or ice around the wheels or wheel
housings.4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM sensors.
NOTE:
•If your vehicle is equipped with a matching full-size
spare wheel and tire assembly, 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 “TIRE LOW PRESSURE” message will be
displayed in the instrument cluster for 60 seconds, and
a chime to sound. Driving the vehicle for up to
20 minutes above 15 mph (24 km/h) will turn OFF the
Tire Pressure Monitoring Telltale Light as long as none
of the road tires are below the low pressure warning
threshold.
360 STARTING AND OPERATING

•If your vehicle is not equipped with a matching
full-size spare wheel and tire assembly, it does not
have a tire pressure monitoring sensor in the spare tire.
The TPMS will not be able to monitor the tire pressure.
If you install the spare tire, in place of a road tire, that
has a pressure below the low-pressure warning limit,
upon the next ignition key cycle, a chime will sound, a
“TIRE LOW PRESSURE” message will be displayed in
the instrument cluster for 60 seconds, and the Tire
Pressure Monitoring Telltale Light will turn ON. After
driving the vehicle for up to 20 minutes above 15 mph
(25 km/h), the Tire Pressure Monitoring Telltale Light
will flash on and off for 75 seconds and then remain on
solid. In addition, a “CHECK TPM SYSTEM” message
will be displayed for 75 seconds. For each subsequent
ignition key cycle, a chime will sound, a “CHECK
TPM SYSTEM” message will be displayed for 75 sec-
onds, and the Tire Pressure Monitoring Telltale Light
will flash on and off for 75 seconds and then remain onsolid. Once you repair or replace the original road tire,
and reinstall it on the vehicle in place of the spare tire,
the TPMS will update automatically and the Tire
Pressure Monitoring Telltale Light will turn OFF, as
long as no tire pressure is below the low-pressure
warning limit in any of the four active road tires. The
vehicle may need to be driven for up to 20 minutes
above 15 mph (24 km/h) in order for the TPMS to
receive this information.
Premium System — If Equipped
The Tire Pressure Monitor System (TPMS) uses wireless
technology with wheel rim-mounted electronic sensors to
monitor tire pressure levels. Sensors, mounted to each
wheel as part of the valve stem, transmit tire pressure
readings to the Receiver Module.
NOTE:It is particularly important, for you to regularly
check the tire pressure in all of your tires and to maintain
the proper pressure.
STARTING AND OPERATING 361

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, theCHECK TPM SYSTEMmessage will not be present, and a pressure value will be
displayed instead of dashes. A system fault can occur by
any of the following:
1. Jamming due to electronic devices or driving next to
facilities emitting the same Radio Frequencies as the TPM
sensors.
2. Installing some form of aftermarket window tinting
that affects radio wave signals.
3. Lots of snow or ice around the wheels or wheel
housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM sensors.
The EVIC will also display aCHECK TPM SYSTEM
message for three seconds when a system fault is de-
tected possibly related to the trigger component. In this
364 STARTING AND OPERATING

case, theCHECK TPM SYSTEMmessage is then fol-
lowed by a graphic display, with pressure values still
shown. This indicates the pressure values are still being
received from the TPM Sensors. However, the system still
needs to be serviced as long as theCHECK TPM
SYSTEMmessage exists.
NOTE:
•If your vehicle is equipped with a matching full-size
spare wheel and tire assembly, 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 20 minutes above 15 mph
(24 km/h) will turn OFF the Tire Pressure MonitoringTelltale Light as long as none of road tires are below
the low pressure warning threshold. The EVIC will
also display a “SPARE LOW PRESSURE” message,
and the graphic display will show a tire pressure value
in place of the “flashing” low tire pressure value.
•If your vehicle is not equipped with a matching
full-size spare wheel and tire assembly, it does not
have a tire pressure monitoring sensor in the spare tire.
The TPMS will not be able to monitor the tire pressure.
If you install the spare tire in place of a road tire that
has a pressure below the low-pressure warning limit,
upon the next ignition key cycle, the Tire Pressure
Monitoring Telltale Light will remain ON, a chime will
sound, and the EVIC will still display a “flashing”
pressure value in the graphic display. After driving the
vehicle for up to 20 minutes above 15 mph (24 km/h),
the Tire Pressure Monitoring Telltale Light will flash
on and off for 75 seconds and then remain on solid. In
addition, the EVIC will display a “CHECK TPM
STARTING AND OPERATING 365

SYSTEMmessage for three seconds and then display
dashes (- -) in place of the pressure value. For each
subsequent ignition key cycle, a chime will sound, the
Tire Pressure Monitoring Telltale Light will flash on
and off for 75 seconds and then remain on solid, and
the EVIC will display aCHECK TPM SYSTEM
message for three seconds and then display dashes (- -)
in place of the pressure value. Once you repair or
replace the original road tire, and reinstall it on the
vehicle in place of the spare tire, the TPMS will update
automatically.
In addition, the Tire Pressure Monitoring Telltale Light
will turn OFF and the graphic in the EVIC will display a
new pressure value instead of dashes (- -), as long as no
tire pressure is below the low-pressure warning limit in
any of the four active road tires. The vehicle may need to
be driven for up to 20 minutes above 15 mph (24 km/h)
in order for the TPMS to receive this information.General Information
