ESC Partial Off
This mode is entered by momentarily pushing
the ESC OFF button.
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
management. 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 push the
ESC OFF button. 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 pushing the ESC OFF
button. Once the situation requiring ESC to be
switched to the “Partial Off” mode is overcome,
turn ESC back on by momentarily pushing the
ESC OFF button. This may be done while the
vehicle is in motion.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
is turned to the ON mode. It should go
out with the engine running. If the ESC
Activation/Malfunction Indicator Light comes
on continuously with the engine running, a
malfunction has been detected in the ESC
system. If this light remains on after several
ignition cycles, and the vehicle has been driven
several miles (kilometers) at speeds greater
than 30 mph (48 km/h), see an authorized
dealer as soon as possible to have the problem
diagnosed and corrected.
The ESC Activation/Malfunction Indicator Light
starts to flash as soon as the tires lose traction
and the ESC system becomes active. The ESC
Activation/Malfunction Indicator Light also
flashes when TCS is active. If the ESC
Activation/Malfunction Indicator Light begins to
flash during acceleration, ease up on the
accelerator and apply as little throttle as
possible. Be sure to adapt your speed and
driving to the prevailing road conditions.
WARNING!
When in “Partial Off” mode, the TCS func -
tionality 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 “Partial
Off” mode, the engine power reduction
feature of TCS is disabled, and the
enhanced vehicle stability offered by the
ESC system is reduced.
Trailer Sway Control (TSC) is disabled when
the ESC system is in the “Partial Off” mode.

Check TPMS Warnings
The Tire Pressure Monitoring System Warning
Light will flash on and off for 75 seconds and
remain on solid when a system fault is detected,
an audible chime will be activated and the “Tire
Pressure Monitoring Unavailable” message will
display. If the ignition key is cycled, this
sequence will repeat providing the system fault
still exists. The TPMS Warning Light will turn off
when the fault condition no longer exists. A
system fault can occur with any of the following
scenarios:
Jamming due to electronic devices or driving
next to facilities emitting the same radio
frequencies as the TPMS sensors
Installing some form of aftermarket window
tinting that affects radio wave signals
Snow or ice around the wheels or wheel
housings
Using tire chains on the vehicle
Using wheels/tires not equipped with TPMS
sensors NOTE:
Your vehicle is equipped with a regular size
spare wheel.

1. The spare tire does not have a TPMS
sensor. Therefore, the TPMS will not
monitor the pressure in the spare tire.

2. If a spare tire not equipped with the Tire Pressure Monitoring system sensor is used,
the TPMS Warning Light will turn on,
flashing for 75 seconds and then remaining
solid for each subsequent ignition key cycle.
3. 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 System Warning Light will
extinguish once the updated tire pressures
have been received. The vehicle may need
to be driven for up to 20 minutes above
15 mph (24 km/h) to receive this
information.
NOTE:
For correct Tire Pressure Monitoring System
behavior, please wait for about 20 minutes in
key-off during each tire substitution.
OCCUPANT RESTRAINT SYSTEMS
Some of the most important safety features in
your vehicle are the restraint systems:
OCCUPANT RESTRAINT SYSTEMS
F
EATURES
Seat Belt Systems
Supplemental Restraint Systems (SRS) Air

Child Restraints

Some of the safety features described in this
section may be standard equipment on some
models, or may be optional equipment on others.
If you are not sure, ask an authorized dealer.

IMPORTANT SAFETY PRECAUTIONS
Please pay close attention to the information in
this section. It tells you how to use your restraint
system properly, to keep you and your
passengers as safe as possible.
