Tire pressure monitoring system
Function of the tire pressure monitoring sys‐

&
DANGER Risk of accident due to incor‐
rect tire pressure
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recommen‐
ded by the vehicle manufacturer on the vehi‐
cle placard or tire inflation pressure label. (If
your vehicle has tires of a different size than
the size indicated on the vehicle placard or
the 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 monitor‐
ing system (TPMS) that illuminates a low tire
pressure telltale when one or more of your
tires is significantly under-inflated. Accord‐
ingly, when the low tire pressure telltale illu‐
minates, you should stop and check your
tires as soon as possible, and inflate them to
the proper pressure. Driving on a signifi‐
cantly 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 han‐
dling 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 sys‐
tem 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 illumina‐
ted, the system may not be able to detect or
signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of rea‐
sons, including the installation of replace‐
ment or alternate tires or wheels on the vehi‐
cle 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 replace‐
ment or alternate tires and wheels allow the
TPMS to continue to function properly.
The system checks the tire pressure and the tire
temperature of the tires installed on the vehicle
by means of a tire pressure sensor.
