Air Suspension Fault Warning Light
If Equipped
This light will illuminate when a fault is
detected with the air suspension system.
Anti-Lock Brake System (ABS) Warning
Light
This warning light monitors the ABS. The
light will turn on when the ignition is placed
in the ON/RUN or ACC/ON/RUN position and
may stay on for as long as four seconds.
If the ABS light remains on or turns on while driving,
then the Anti-Lock portion of the brake system is not
functioning and service is required as soon as possible.
However, the conventional brake system will continue to
operate normally, assuming the Brake Warning Light is
not also on.
If the ABS light does not turn on when the ignition is
placed in the ON/RUN or ACC/ON/RUN position, have
the brake system inspected by an authorized dealer.
Electronic Stability Control (ESC) Active
Warning Light If Equipped
This warning light will indicate when the ESC
system is Active. The ESC Indicator Light in
the instrument cluster will come on when the
ignition is placed in the ON/RUN or ACC/ON/
RUN position, and when ESC is activated. It should go
out with the engine running. If the ESC Indicator Light
comes on continuously with the engine running, a mal-
function has been detected in the ESC system. If this
warning light remains on after several ignition cycles,
and the vehicle has been driven several miles (kilome-
ters) at speeds greater than 30 mph (48 km/h), see an
authorized dealer as soon as possible to have the prob-
lem diagnosed and corrected.
The ESC OFF Indicator Light and the ESC Indicator
Light come on momentarily each time the ignition is
placed in the ON/RUN or ACC/ON/RUN position.
The ESC system will make buzzing or clicking
sounds when it is active. This is normal; the sounds
will stop when ESC becomes inactive.
This light will come on when the vehicle is in an ESC
event.
Electronic Stability Control (ESC) OFF
Warning Light If Equipped
This warning light indicates the ESC is off.
Each time the ignition is turned to ON/RUN
or ACC/ON/RUN, the ESC system will be on,
even if it was turned off previously.
LaneSense Warning Light If Equipped
The LaneSense system provides the driver
with visual and steering torque warnings when
the vehicle starts to drift out of its lane unin-
tentionally without the use of a turn signal.
When the LaneSense system senses a lane drift
situation, the LaneSense indicator changes from
solid green to solid yellow.
When the LaneSense system senses the lane has
been approached and is in a lane departure situa-
tion, the LaneSense indicator changes from solid
white/green to flashing yellow
