ESC Operating Modes
NOTE:Depending upon model and mode of operation,
the ESC system may have multiple operating modes.
ESC On
This is the normal operating mode for the ESC. When-
ever the vehicle is started, the ESC system will be in this
mode. This mode should be used for most driving
conditions. Alternate ESC modes should only be used for
specific reasons as noted in the following paragraphs.
Partial Off
The “Partial Off” mode is intended for times when a
more spirited driving experience is desired. This mode
may modify TCS and ESC thresholds for activation,
which allows for more wheel spin than normally al-
lowed. This mode may be useful if the vehicle becomes
stuck. To enter the “Partial Off” mode, momentarily push the
“ESC Off” switch and the “ESC Off Indicator Light” will
illuminate. To turn the ESC on again, momentarily push
the “ESC Off” switch and the “ESC Off Indicator Light”
will turn off.
NOTE:
For vehicles with multiple partial ESC modes a
momentary button push will toggle the ESC mode.
Multiple momentary button pushed may be required to
return to ESC On.
NOTE:
• When in “Partial Off” mode, the TCS functionality 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.

STARTING AND OPERATING 517

Full Off – If Equipped
This mode is intended for off-highway or off-road use
only and should not be used on any public roadways. In
this mode, TCS and ESC features are turned OFF. To enter
the “Full Off” mode, push 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 Off Indicator Light” will illuminate, and the
“ESC OFF” message will display in the Electronic Vehicle
Information Center (EVIC). To turn ESC ON again,
momentarily push the “ESC Off” switch.
NOTE:System may switch from ESC Full Off to Partial
mode when vehicle exceeds a predetermined speed.
When the vehicle speed slows below the predetermined
speed the system will return to ESC Full Off.
ESC modes may also be affected by drive modes – if
equipped.WARNING!
• In the ESC “Full Off” mode, the engine torque
reduction and stability features are disabled.
Therefore, enhanced vehicle stability offered by
the ESC system 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.
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 turned to the ON
position. 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 your autho-
rized dealer as soon as possible to have the problem
diagnosed and corrected.
The “ESC Activation/Malfunction Indicator Light” (lo-
cated in the instrument cluster) 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 ac-
celeration, 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.NOTE:
•
The “ESC Activation/Malfunction Indicator Light”
and the “ESC OFF Indicator Light” come on momen-
tarily each time the ignition switch is turned ON.
• Each time the ignition is turned ON, the ESC system
will be ON even if it was turned off previously.
• The ESC system will make buzzing or clicking sounds
when it is active. This is normal; the sounds will stop
when ESC becomes inactive following the maneuver
that caused the ESC activation.
The “ESC OFF Indicator Light” indicates the
customer has elected to have the Electronic
Stability Control (ESC) in a reduced mode.

swaying. Always use caution when towing a trailer and
follow the trailer tongue weight recommendations. Refer
to “Trailer Towing” in this section for further informa-
tion.
When TSC is functioning, the “ESC Activation/
Malfunction Indicator Light” will flash, the engine power
may be reduced and you may feel the brakes being
applied to individual wheels to attempt to stop the trailer
from swaying. TSC is disabled when the ESC system is in
the “Partial Off” or “Full Off” modes.
WARNING!
If TSC activates while driving, slow the vehicle
down, stop at the nearest safe location, and adjust the
trailer load to eliminate trailer sway.
Ready Alert Braking (RAB)
Ready Alert Braking may reduce the time required to
reach full braking during emergency braking situations.
It anticipates when an emergency braking situation may
occur by monitoring how fast the throttle is released by
the driver. The EBC will prepare the brake system for a
panic stop.
Rain Brake Support (RBS)
Rain Brake Support may improve braking performance
in wet conditions. It will periodically apply a small
amount of brake pressure to remove any water buildup
on the front brake rotors. It functions when the wind-
shield wipers are in LO or HI speed. When Rain Brake
Support is active, there is no notification to the driver and
no driver interaction is required.

NOTE:
•P (Passenger) — Metric tire sizing is based on U.S.
design standards. P-Metric tires have the letter “P”
molded into the sidewall preceding the size designa-
tion. Example: P215/65R15 95H.
• European — Metric tire sizing is based on European
design standards. Tires designed to this standard have
the tire size molded into the sidewall beginning with
the section width. The letter Pis absent from this tire
size designation. Example: 215/65R15 96H.
• LT (Light Truck) — Metric tire sizing is based on U.S.
design standards. The size designation for LT-Metric
tires is the same as for P-Metric tires except for the
letters “LT” that are molded into the sidewall preced-
ing the size designation. Example: LT235/85R16. •
Temporary spare tires are designed for temporary
emergency use only. Temporary high pressure com-
pact spare tires have the letter “T” or “S” molded into
the sidewall preceding the size designation. Example:

EXAMPLE:
Service Description: 95= Load Index
– A numerical code associated with the maximum load a tire can carry
H = Speed Symbol
– A symbol indicating the range of speeds at which a tire can carry a load corresponding to
its load index under certain operating conditions
– The maximum speed corresponding to the speed symbol should only be achieved under
specified operating conditions (i.e., tire pressure, vehicle loading, road conditions, and
posted speed limits)
Load Identification:
Absence of the following load identification symbols on the sidewall of the tire indicates a Standard Load (SL) tire:

532 STARTING AND OPERATING

These indicators are molded into the bottom of the tread
grooves. They will appear as bands when the tread depth
becomes a 1/16 of an inch (1.6 mm). When the tread is
worn to the tread wear indicators, the tire should be
replaced. Refer to “Replacement Tires” in this section for
further information.
Life Of Tire
The service life of a tire is dependent upon varying
factors including, but not limited to:
•Driving style.
•
Tire pressure - Improper cold tire inflation pressures can
cause uneven wear patterns to develop across the tire
tread. These abnormal wear patterns will reduce tread
life, resulting in the need for earlier tire replacement.
• Distance driven. •
Performance tires, tires with a speed rating of V or
higher, and Summer tires typically have a reduced
tread life. Rotation of these tires per the vehicle main-
tenance schedule is highly recommended.
WARNING!
Tires and the spare tire should be replaced after six
years, regardless of the remaining tread. Failure to
follow this warning can result in sudden tire failure.
You could lose control and have a collision resulting
in serious injury or death.
Keep dismounted tires in a cool, dry place with as little
exposure to light as possible. Protect tires from contact
with oil, grease, and gasoline.5
