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 igni-
tion is turned to the "ESC on" mode. It should go out
with the engine running. If the "ESC Activation/Malfunc-
tion 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 condi-
tions.
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 situa-
tions. HDC controls vehicle speed by actively controlling the
brakes.
