If a problem is detected, the light will come on while the engine is running. Cycle the
ignition when the vehicle has completely stopped and the shift lever is placed in the
PARK position; the light should turn off.
If the light remains lit with the engine running, your vehicle will usually be drivable.
However, see an authorized dealer immediately. If the light is flashing when the engine
is running, immediate service is required, and you may experience reduced perfor-
mance, an elevated/rough idle or engine stall, and your vehicle may require towing.
- Tire Pressure Monitoring System (TPMS) Light
Each tire, including the spare (if provided), should be checked monthly when cold
and inflated to the inflation pressure recommended by the vehicle manufacturer on
the vehicle placard or tire inflation pressure label. (If your vehicle 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 pressure 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 pressure. Driving on a significantly 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.
IF THE LIGHT STARTS FLASHING INDICATING A LOW TIRE PRESSURE, ADJUST THE AIR
PRESSURE IN THE LOW TIRE TO THE AIR PRESSURE SHOWN ON THE VEHICLE PLACARD OR
TIRE INFLATION PRESSURE LABEL LOCATED ON THE DRIVER'S DOOR.
NOTE:
AFTER INFLATION, THE VEHICLE MAY NEED TO BE DRIVEN FOR 20 MINUTES
BEFORE THE FLASHING LIGHT WILL TURN OFF.
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.
