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 turned to the "ESC on" 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 (km) 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.
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.
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)

Park brake is released

Driver door is closed (If doors are attached,

then door must be closed. If doors are
detached, then driver seatbelt must be
buckled)
