Light is not also on.
If the ABS light does not turn on when the igni-
tion 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 Electronic Stability Control 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 acti-
vated. It should go out with the engine running.
If the “ESC Indicator Light” comes on continu-
ously with the engine running, a malfunction
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 (kilometers) at speeds greater than
30 mph (48 km/h), see an authorized dealer as
soon as possible to have the problem diag-
nosed 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 Elec-
tronic Stability Control (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.
Loose Fuel Filler Cap Warning Light — If
Equipped
This warning light will illuminate when
the fuel filler cap is loose. Properly
close the filler cap to disengage the
light. If the light does not turn off,
please see an authorized dealer.
Low Fuel Warning Light
When the fuel level reaches approxi-
mately 2.0 gal (7.5 L), this light will
turn on and a chime will sound. The
light will remain on until fuel is added.
Low Washer Fluid Warning Light — If Equipped
This warning light will illuminate when
the windshield washer fluid is low.
Engine Check/Malfunction Indicator Warning
Light (MIL)
The Engine Check/Malfunction Indi-
cator Light (MIL) is a part of an
Onboard Diagnostic System called
OBD II that monitors engine and auto-
matic transmission control systems. This
warning light will illuminate when the ignition is
in the ON/RUN position before engine start. If
the bulb does not come on when turning the
ignition switch from OFF to ON/RUN, have the
condition checked promptly.
Certain conditions, such as a loose or missing
gas cap, poor quality fuel, etc., may illuminate
the light after engine start. The vehicle should
be serviced if the light stays on through several
typical driving styles. In most situations, the
vehicle will drive normally and will not require
towing.
When the engine is running, the MIL may flash
to alert serious conditions that could lead to
immediate loss of power or severe catalytic
converter damage. The vehicle should be
