GETTING TO KNOW YOUR INSTRUMENT PANEL 43
under-inflated tire causes the tire to overheat
and can lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread life, and
may affect the vehicle’s handling and stopping
ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire
pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The TPMS
malfunction indicator is combined with the low
tire pressure telltale. When the system detects
a malfunction, the telltale will flash for
approximately one minute and then remain
continuously illuminated. This sequence will
continue upon subsequent vehicle start-ups as
long as the malfunction exists. When the
malfunction indicator is illuminated, the system
may not be able to detect or signal low tire
pressure as intended. TPMS malfunctions may
occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replacing one or
more tires or wheels on your vehicle to ensure
that the replacement or alternate tires and
wheels allow the TPMS to continue to function
properly.
Anti-Lock Brake System (ABS) Warning
Light
This light monitors the Anti-Lock
Brake System (ABS). The light will turn
on when the ignition is placed in the
ON/RUN or MAR/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. 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 is placed in
the ON/RUN or MAR/ON/RUN position, have
the light inspected by an authorized dealer.
Electronic Stability Control (ESC) Warning
Light — If Equipped
The Electronic Stability Control (ESC)
Indicator Light in the instrument
cluster will come on when the ignition
is placed in the ON/RUN or MAR/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 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 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 MAR (ON/
RUN) or AVV (START) position.

Each time the ignition is turned to MAR (ON/
RUN) or AVV (START), 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.

This light will come on when the vehicle is in
an ESC event.
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures
and warning have been established for the tire
size equipped on your vehicle. Undesirable
system operation or sensor damage may result
when using replacement equipment that is not
of the same size, type, and/or style.
Aftermarket wheels can cause sensor damage.
Using aftermarket tire sealants may cause the
Tire Pressure Monitoring System (TPMS)
sensor to become inoperable. After using an
aftermarket tire sealant it is recommended
that you take your vehicle to an authorized
dealer to have your sensor function checked.
