NOTE:To improve the vehicle’s traction when driving
with snow chains, or when starting off in deep snow,
sand, or gravel, it may be desirable to switch to the
“Partial Off” mode by momentarily pressing the “ESC
Off” switch. Once the situation requiring “Partial Off”
mode is overcome, turn the ESC ON again by momen-
tarily pressing the “ESC Off” switch. This may be done
while the vehicle is in motion.
WARNING!
• When in “Partial Off” mode, the TCS functionality
of ESC, (except for the limited slip feature de-
scribed in the TCS section), has been disabled and
the “ESC Off Indicator Light” will be illuminated.
When in “Partial Off” mode, the engine power
reduction feature of TCS is disabled, and the
enhanced vehicle stability offered by the ESC sys-
tem is reduced. Full Off
This mode is intended for off-highway or off-road use
only and should not be used on any public roadways. In
this mode, all TCS and ESC stability features are turned
OFF. To enter the “Full Off” mode, press and hold the
“ESC Off” switch for five seconds while the vehicle is
stopped with the engine running. After five seconds, a
chime will sound, the “ESC Activation/Malfunction In-
dicator Light” will illuminate, and the
ESC OFFmes-
sage will display in the vehicle odometer. Press and
release the TRIP ODOMETER button located on the
instrument cluster to clear this message. The “ESC OFF”
message may appear in the Electronic Vehicle Informa-
tion Center (EVIC). Refer to “Electronic Vehicle Informa-
tion Center (EVIC)” in “Understanding Your Instrument
Panel” for further information. To turn ESC ON again,
momentarily press the “ESC Off” switch.

NOTE:TheESC OFF message will display and the
audible chime will sound when the shift lever is moved
into the PARK position from any position other than
PARK and then moved out of the PARK position. This
will occur when the message was previously cleared.
WARNING!
In the ESC “Full Off” mode, the engine torque
reduction and stability features are disabled. There-
fore, the enhanced vehicle stability offered by ESC is
unavailable. In an emergency evasive maneuver, the
ESC system will not engage to assist in maintaining
stability. ESC Off mode is intended for off-highway
or off-road use only. NOTE:
When the ESC is switched OFF, a feature of the
system remains active. This feature controls wheel spin
across an axle quite similarly to a limited slip differential.
If one wheel on an axle is spinning faster than the other,
the system will apply the brake of the spinning wheel
and allow more engine torque to be applied to the wheel
that is not spinning. To improve the vehicle’s traction
when driving with tire chains, or when starting off in
deep snow, sand, or gravel, it may be desirable to switch
to the “Partial Off” mode by momentarily pressing the
“ESC Off” switch.
ESC Activation/Malfunction Indicator Light And
ESC OFF Indicator Light
The “ESC Activation/Malfunction Indicator
Light” in the instrument cluster will come on
when the ignition switch is cycled to the ON
position. It should go out with the engine
342 STARTING AND OPERATING
Page 375 of 520

If the ignition switch is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault
no longer exists, the “TPM Telltale Light” will no longer
flash, and theSERVICE TPM SYSTEM message will no
longer display, and a pressure value will display in place
of the dashes. A system fault can occur due to any of the
following:
1. Signal interference due to electronic devices or driving next to facilities emitting the same radio frequencies as
the TPM sensors.
2. Installing aftermarket window tinting that contains materials that may block radio wave signals.
3. Accumulation 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 related to an incorrect sensor location fault is
detected. In this case, the SERVICE TPM SYSTEM
message is then followed with a graphic display with
pressure values still shown. This indicates that the pres-
sure values are still being received from the TPM sensors
but they may not be located in the correct vehicle
position. The system still needs to be serviced as long as
the SERVICE TPM SYSTEM message is displayed.
Vehicles with Compact Spare
1. The compact spare tire does not have a TPM sensor. Therefore, the TPMS will not monitor the pressure in
the compact spare tire.
2. If you install the compact spare tire in place of a road tire that has a pressure below the low-pressure warn-
ing limit, upon the next ignition switch cycle, the
“TPM Telltale Light” will remain ON and a chime will
