340 STARTING AND OPERATING

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.
ESC OFF Switch
386 STARTING AND OPERATING

WARNING! (Continued)
•Failure to equip your vehicle with tires having
adequate speed capability can result in sudden tire
failure and loss of vehicle control.
CAUTION!
Replacing original tires with tires of a different size
may result in false speedometer and odometer read-
ings.
TIRE CHAINS (TRACTION DEVICES)
Use of traction devices require sufficient tire-to-body
clearance. Follow these recommendations to guard
against damage.
•Install on Rear Tires Only
•Due to limited clearance, use SAE class “S” low profile
cables or traction devices only. Security Chain Com-
pany (SCC) Super Z6 #SZ 441 cables or equivalent are
recommended.
WARNING!
Using tires of different size and type (M+S, Snow)
between front and rear axles can cause unpredictable
handling. You could lose control and have a collision.
CAUTION!
To avoid damage to your vehicle or tires, observe the
following precautions:(Continued)
412 STARTING AND OPERATING

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 “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 (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” mes-
sage will be displayed for 75 seconds. For each subse-
quent ignition switch cycle, a chime will sound, a “SER-
VICE TPM SYSTEM” message will be displayed for
75 seconds, and the Tire Pressure Monitoring Telltale
Light will flash on and off for 75 seconds and then remain
on solid. 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.

STARTING AND OPERATING 419

NOTE:Your system can be set to display pressure units
in PSI, kPa, or BAR.
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, the SERVICE 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 a
SERVICE TPM SYSTEM
message for a minimum of five seconds when a system
fault is detected possibly related to the trigger compo-
nent an incorrect sensor location fault. In this case, the
