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 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 Electronic 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.
Low Fuel Warning Light
When the fuel level reaches approximately 2.8 gal (10.6 L),
this light will turn on and a chime will sound. The light
will remain on until fuel is added.
Engine Check/Malfunction Indicator Warning
Light (MIL)
The Engine Check/Malfunction Indicator Light (MIL) is a
part of an Onboard Diagnostic System called OBD II that
monitors engine and automatic transmission control sys-
tems. 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 ve-
hicle 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 serviced as soon as possible if this occurs.
