As an added safety feature, your vehicle has been equipped with a Tire Pressure
Monitoring System (TPMS) which display in the instrument cluster display when one or
more of your tires is significantly under-inflated. Accordingly, when the low tire pressure
instrument cluster display 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 instrument cluster display
message.
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 each time the vehicle is restarted 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.
NOTE:
Tire pressures change by approximately 1 psi (7 kPa) per 12° F (7° C) of air temperature
change. Keep this in mind when checking tire pressure inside a garage, especially in the
Winter. Example: If garage temperature is 68°F (20°C) and the outside temperature is
32°F (0°C), then the cold tire inflation pressure should be increased by 3 psi (21 kPa),
which equals 1 psi (7 kPa) for every 12°F (7°C) for this outside temperature condition.
