features of ESC function normally. This mode is intended
to be used if the vehicle is in deep snow, sand, or gravel
conditions and more wheel spin than ESC would nor-
mally allow is required to gain traction. To turn ESC on
again, momentarily press the “ESC OFF” switch. This
will restore the normal “ESC On” mode of operation.NOTE:To improve the vehicle’s traction when driving
with snow chains, or starting off in deep snow, sand, or
gravel, it may be desirable to switch to the “Partial Off”
mode by pressing the “ESC OFF” switch. Once the
situation requiring ESC to be switched to the “Partial
Off” mode is overcome, turn ESC back on by momen-
tarily pressing the “ESC OFF” switch. This may be done
while the vehicle is in motion.
4WD Low Range
Partial Off
This is the normal operating mode for ESC in 4WD LOW
range. Whenever the vehicle is started in 4WD LOW
range, or the transfer case (if equipped) is shifted from
4WD HIGH range or NEUTRAL to 4WD LOW range, the
ESC system will be in the “Partial Off” mode.

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 “SERVICE TPM
SYSTEM” message may be displayed for approximately
5 seconds when a system fault is detected, and a chime
will sound. If the ignition switch is cycled, this sequence
will repeat, providing the system fault still exists. The
Tire Pressure Monitoring 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:
There is no 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 switch cycle, a chime will sound, a
“LOW TIRE PRESSURE” message will be displayed in the
instrument cluster for a minimum of five seconds, an
Inflate to XXXmessage will be displayed and the Tire
Pressure Monitoring Telltale Light will turn ON. 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, a “SERVICE TPM SYSTEM” message will be
displayed for a minimum of five seconds. For each subse-
quent ignition switch cycle, a chime will sound, a “SER-
VICE TPM SYSTEM” message will be displayed for a

If the ignition switch 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 TPM SYSTEM
message 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 aSERVICE TPM SYSTEM
message for a minimum of five seconds when a system
fault is detected possibly related to an incorrect sensor
location fault. In this case, theSERVICE TPM SYSTEM
message is then followed by a graphic display, with
pressure values still shown. This indicates the pressure
values are still being received from the TPM Sensors but
they may not be located in the correct vehicle position.
However, the system still needs to be serviced as long as
theSERVICE TPM SYSTEMmessage exists.
NOTE:There is no 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 switch 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 and anInflate to
