WARNING! (Continued)
The Electronic Stability Control (ESC)

cannot prevent the natural laws of physics
from acting on the vehicle, nor can it
increase the traction afforded by prevailing
road conditions. ESC cannot prevent all
accidents, including those resulting from
excessive speed in turns, driving on very
slippery surfaces, or hydroplaning. ESC also
cannot prevent collisions.
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 placed in the ON/RUN 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" (located 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 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.
NOTE:
The "ESC Activation/Malfunction Indicator

Light" and the "ESC OFF Indicator Light"
come on momentarily each time the ignition
is turned ON/RUN.
Each time the ignition is turned ON/RUN, 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.
Hill Descent Control (HDC) — If Equipped
Hill Descent Control (HDC) is intended
for low speed off road driving while in
4L Range. HDC maintains vehicle
speed while descending hills during
various driving situations. HDC controls vehicle
speed by actively controlling the brakes.
HDC Has Three States:
1. Off (feature is not enabled and will not
activate)
2. Enabled (feature is enabled and ready but
activation conditions are not met, or driver
is actively overriding with brake or throttle
application)
3. Active (feature is enabled and actively
controlling vehicle speed)
