Jeep Wrangler: Electronic Stability Control (ESC) / 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
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.
The ESC OFF Indicator Light
indicates
the customer has elected to have the
Electronic Stability Control (ESC) in a
reduced mode.
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 place in the ON position,
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 “Full Off” mode is intended for off-highway
or off-road use only and should not be used on
any public roadways. In this mode, TCS and ESC
features are turned off...
HDC is intended for low speed off-road driving
while in 4WD Low. HDC maintains vehicle speed
while descending hills during various driving
situations...
Other information:
The warning light switches on
and a
message is displayed to indicate that
the tire pressure is lower than the
recommended value and/or that slow
pressure loss is occurring. In these cases,
optimal tire duration and fuel consumption may
not be guaranteed...
Snow
In heavy snow or for additional control and
traction at slower speeds, shift the transmission
into a low gear and the transfer case into 4WD
Low if necessary. Do not shift to a lower gear
than necessary to maintain headway.
Over-revving the engine can spin the wheels
and traction will be lost...
