When in the “Partial Off” mode, the TCS portion of ESC,
except for the “limited slip” feature described in the TCS
section, has been disabled and the “ESC OFF Indicator
Light” will be illuminated. When in the “Partial Off”
mode, ESC will operate without engine torque manage-
ment. 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 normally 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.
WARNING!
•When inPartial Offmode, the TCS functionality
of ESC, (except for the limited slip feature de-
scribed in the TCS section), has been disabled and
theESC Off Indicator Lightwill be illuminated.
(Continued)
WARNING!(Continued)
When inPartial Offmode, the engine power
reduction feature of TCS is disabled, and the
enhanced vehicle stability offered by the ESC sys-
tem is reduced.
•Trailer Sway control (TSC) is disabled when the
ESC system is in thePartial Offmode.
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 situa-
tion requiring ESC to be switched to the “Partial Off”
mode is overcome, turn ESC back on by momentarily
pressing the “ESC Off” switch. This may be done while
the vehicle is in motion.
490 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 readings.
TIRE CHAINS (TRACTION DEVICES)
Use of traction devices require sufficient tire-to-body clear-
ance. Follow these recommendations to guard against
damage:
•Traction device must be of proper size for the tire, as
recommended by the traction device manufacturer.
•Install on front tires only.•225/65R16 and 235/60R16 tires with the use of a
traction device that meets the SAE type “Class S”
specification is recommended.
•
Due to limited clearance, P225/65R17 and 225/65R17
tires with a Security Chain Company (SCC) Super Z6 low
profile traction device or equivalent is 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.5
STARTING AND OPERATING 517

Tire Pressure Monitoring Low Tire Pressure
Warnings
The “Tire Pressure Monitoring Telltale Light”
will illuminate in the instrument cluster, a “LOW
TIRE PRESSURE” message will display in the
instrument cluster, and an audible chime will be
activated when one or more of the four active road tire
pressures are low. 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 recom-
mended cold tire placard pressure value (located on the
placard label on the driver’s-side B-Pillar). The system will
automatically update and the “Tire Pressure Monitoring
Telltale Light” will extinguish once the updated tire pres-
sures have been received.
NOTE:The vehicle may need to be driven for up to
20 minutes above 15 mph (24 km/h) to receive this
information.The “Tire Pressure Monitoring Telltale Light” will flash
on and off for 75 seconds, and remain on solid when a
system fault is detected. The system fault will also sound
a chime. 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 with any of the following scenarios:
1. Jamming due to electronic devices or driving next to
facilities emitting the same radio frequencies as the
TPMS sensors.
2. Installing some form of aftermarket window tinting
that affects radio wave signals.
3. Accumulation of excessive snow and/or ice around
the wheels or wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPMS sensors.

STARTING AND OPERATING 523

SERVICE TPM SYSTEM Message
The “Tire Pressure Monitoring Telltale Light” will flash on
and off for 75 seconds, and remain on solid when a system
fault is detected. The system fault will also sound a chime.
The EVIC will display a “SERVICE TPM SYSTEM” message
for a minimum of five seconds. This text message is then
followed by a graphic display, with--in place of the
pressure value(s) indicating which TPMS Sensor(s) is not
being received.
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 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 scenarios:
1. Jamming due to electronic devices or driving next to
facilities emitting the same radio frequencies as the
TPMS sensors.2. Installing some form of aftermarket window tinting
that affects radio wave signals.
3. Accumulation of excessive snow and/or ice around
the wheels or wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPMS sensors.
The EVIC will also display a “SERVICE TPM SYSTEM”
message for a minimum of five seconds when a system
fault possibly related to an incorrect sensor location fault
is present. In this case, the “SERVICE TPM SYSTEM”
message is then followed by 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 in the correct vehicle position. The
system still needs to be serviced as long as the “SERVICE
TPM SYSTEM” message exists.
