ESP/TCS Indicator Light
The ESP/TCS Indicator" light located
in the instrument cluster, starts to
flash as soon as the tires lose traction
and the ESP system becomes active.
The ESP/TCS Indicator" light also
flashes when TCS is active. If the
ESP/TCS 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!
ESP (Electronic Stability Program) cannot pre-
vent the natural laws of physics from acting on
the vehicle, nor can it increase the traction
afforded by prevailing road conditions. ESP can-
not prevent accidents, including those resulting
from excessive speed in turns, driving on very
slippery surfaces, or hydroplaning. Only a safe,
attentive, and skillful driver can prevent acci-
dents. The capabilities of an ESP-equipped ve-
hicle must never be exploited in a reckless or
dangerous manner, which could jeopardize the
user's safety or the safety of others.

Depending upon model and mode of operation,
the ESP system has up to three operating modes:
"ESP On" "Partial Off," and "Full Off."
ESP On — 2WD Vehicles & 4WD Vehicles in
2WD & 4WD High Range
This is the normal operating mode for ESP when
operating a 2WD vehicle. It is also the normal
mode for operating a 4WD vehicle in 2WD or 4WD
high range. The ESP system will be in "ESP On"
mode whenever the vehicle is started or the
transfer case (if equipped) is shifted out of 4WD
low range. This mode should be used for most
driving situations. ESP should only be turned to
"Partial Off" or "Full Off" for specific reasons as
noted. Refer to "Partial Off" and to "Full Off" for
additional information.
Partial Off — 2WD Vehicles & 4WD Vehicles
in 2WD & 4WD High Range
The "Partial Off" mode is intended for driving in
deep snow, sand, or gravel. This mode raises the
threshold for TCS and ESP activation, which al-
lows for more wheel spin than what ESP normally
allows.
The "ESP OFF" button is located in the lower
switch bank below the climate Control. To enter
the "Partial Off" mode, momentarily depress the
ESP OFF button and the ESP/TCS Indicator" light
will illuminate. To turn the ESP on again, momen-
tarily depress the ESP OFF button and the ESP/
TCS Indicator" light will turn off. This will restore
the normal "ESP On" mode of operation.
ESP Off Button
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 momen-
tarily depressing the ESP OFF button. Once
the situation requiring "Partial Off" mode is
overcome, turn ESP back on by momentarily
depressing the ESP OFF button. This may be
done while the vehicle is in motion.
