CAUTION!
could affect fuel economy and driveability.
If the MIL is flashing, severe catalytic
converter damage and power loss will soon
occur. Immediate service is required.
— Electronic Stability Control (ESC)
Indicator Light
The "ESC Indicator Light" in the instrument
cluster will come on when the ignition is
placed in the ON/RUN position. It should go
out when the engine is running. If the "ESC
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
(kilometers) at speeds greater than 30 mph
(48 km/h), see your 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 momen-
tarily each time the ignition is placed in the
ON/RUN position.
• Each time the ignition is placed in the
ON/RUN position, the ESC system will be
ON, even if it was turned off previously.
• The ESC system will make buzzing or click-
ing sounds when it is active. This is normal;
the sounds will stop when ESC becomes
inactive following the maneuver that
caused the ESC activation.
This telltale indicates that an ESC event is
active.
— Electronic Stability Control (ESC)
OFF Indicator Light — If Equipped
This light indicates the Electronic Stability
Control (ESC) is off.
— Anti-Lock Brake (ABS) Indicator
Light
This light monitors the Anti-Lock Brake Sys-
tem (ABS). The light will turn on when the
ignition switch is placed in the ON/RUN po-
sition 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. However, the conventional brake
system will continue to operate normally if
the brake warning light is not on.
If the ABS light is on, the brake system
should be serviced as soon as possible to
restore the benefits of Anti-Lock Brakes. If
the ABS light does not turn on when the
ignition switch is placed in the ON/RUN po-
sition, have the light inspected by an autho-
rized dealer.
— Tire Pressure Monitoring System
(TPMS) Warning Light
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 con-
sumption may not be guaranteed.
Should one or more tires be in the condition
mentioned above, the display will show the
indications corresponding to each tire in
sequence.
