Traction Control System (TCS)
This system monitors the amount of wheel spin of each
driven wheel. If wheel spin is detected, brake pressure is
applied to the slipping wheel(s) and engine power is
reduced to provide enhanced acceleration and stability.
A feature of the TCS system functions similar to a
limited-slip differential and controls the wheel spin
across a driven axle. If one wheel on a driven axle is
spinning faster than the other, the system will apply the
brake of the spinning wheel. This will allow more engine
torque to be applied to the wheel that is not spinning.
This feature remains active even if TCS and ESP are in the
“Partial Off” or “Full Off” modes. Refer to “Electronic
Stability Program (ESP)” in this section for more infor-
mation.
NOTE:The LSD is a true LSD and the TCS function is
similar to a limited-slip differential.
Brake Assist System (BAS)
This system complements the ABS by optimizing the
vehicle braking capability during emergency braking
maneuvers. This system detects an emergency braking
situation by sensing the rate and amount of brake appli-
cation and then applies optimum pressure to the brakes.
This can help reduce braking distances.
Applying the brakes very quickly results in the best BAS
assistance. To receive the benefits of this system, you
must apply continuous brake pedal pressure during the
stopping sequence. Do not reduce brake pedal pressure
unless braking is no longer desired. Once the brake pedal
is released, the BAS is deactivated.

mode is overcome, turn the ESP ON again by momen-
tarily pressing the “ESP OFF” switch. This may be done
while the vehicle is in motion.
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 ESP stability features are turned
OFF. To enter the “Full Off” mode, press and hold the
“ESP OFF” switch for five seconds while the vehicle is
stopped with the engine running. After five seconds, a
chime will sound, the “ESP/TCS Indicator Light” will
illuminate, and theESP OFFmessage will display in the
vehicle odometer. Press and release the TRIP ODOM-
ETER button located on the instrument cluster to clear
this message. The “ESP OFF” message may appear in the
Electronic Vehicle Information Center (EVIC). Refer to “Electronic Vehicle Information Center (EVIC)” in “Un-
derstanding Your Instrument Panel” for further informa-
tion. To turn ESP ON again, momentarily press the “ESP
OFF” switch.
NOTE:
TheESP 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 ESP “Full Off” mode, the engine torque
reduction and stability features are cancelled. There-
fore, the enhanced vehicle stability offered by ESP is
unavailable.
NOTE: When the ESP 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
“ESP OFF” switch.
WARNING!
With the ESP switched OFF, the enhanced vehicle
stability offered by ESP is unavailable. In an emer-
gency evasive maneuver, the ESP system will not
engage to assist in maintaining stability. The “Full
Off” ESP mode is intended for off-highway or off-
road only.
ESP/BAS Malfunction Indicator Light and
ESP/TCS Indicator Light
The Malfunction Indicator Light for the ESP is
combined with the BAS indicator. The “ESP/
BAS Malfunction Indicator Light” and the
“ESP/TCS Indicator Light” in the instrument
cluster both come on when the ignition switch is turned
to the ON position. They should go out with the engine
running.
The system will turn the “ESP/BAS Malfunction Indica-
tor Light” on continuously while the engine is running if
it detects a malfunction in either the ESP or the BAS or
both. If the light remains on after several ignition cycles
and you have driven the vehicle several miles (kilome-
ters) at speeds greater than 30 mph (48 km/h), and the
ESP is synchronized (refer to Synchronizing ESP), see
your authorized dealer as soon as possible to have the
problem diagnosed and corrected.
