SAFETY
WARNING!
With the ESC switched off, the enhanced
vehicle stability offered by ESC is unavailable.
In an emergency evasive maneuver, the ESC
system will not engage to assist in maintaining
stability. ESC "Full Off" mode is only intended
for off-highway or off-road use.
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 condi-
tions. 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 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 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 placed in
the ON position.
Each time the ignition is placed in the ON posi-
tion, 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)
Enabling HDC
HDC is enabled by pushing the HDC switch, but the
following conditions must also be met to enable
HDC:
Driveline is in 4L Range
Vehicle speed is below 5 mph (8 km/h)
Parking brake is released
Driver door is closed
