ard or tire inflation pressure label. (If your ve-
hicle has tires of a different size than the size
indicated on the vehicle placard or tire inflation
pressure label, you should determine the proper
tire inflation pressure for those tires.)
As an added safety feature, your vehicle has
been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire pres-
sure telltale when one or more of your tires is
significantly under-inflated. Accordingly, when
the low tire pressure telltale illuminates, you
should stop and check your tires as soon as
possible, and inflate them to the proper pres-
sure. Driving on a significantly under-inflated tire
causes the tire to overheat and can lead to tire
failure. Under-inflation also reduces fuel effi-
ciency 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 approxi-
mately one minute and then remain continu-
ously illuminated. This sequence will continue
upon subsequent vehicle start-ups as long as
84
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 re-
placement or alternate tires and wheels allow
the TPMS to continue to function properly.
CAUTION!
The TPMS has been optimized for the origi-
nal equipment tires and wheels. TPMS pres-
sures and warning have been established for
the tire size equipped on your vehicle. Unde-
sirable system operation or sensor damage
may result when using replacement equip-
ment 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 recom-
mended that you take your vehicle to your
authorized dealer to have your sensor func-
tion checked.
— Towing Hook Breakdown Warning
Light — If Equipped

Yellow Indicator Lights

— Active Speed Limiter Fault Indicator
Light — If Equipped
This light will turn on when there is a fault
detected with the Active Speed Limiter.
— Anti-Lock Brake (ABS) Indicator Light
This light monitors the Anti-Lock Brake System
(ABS). The light will turn on when the ignition
switch is placed in the 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 re-
quired. 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 position, have the light
inspected by an authorized dealer.
