WHEELS AND TIRES
480
CAUTION
•
After inflating the tires, always reinstall
the valve cap to help avoid damage to the
valve from dirt, gravel, etc.
•
Use plastic valve caps only. Metal caps
could corrode and become difficult to
remove.

Tire Pressure Monitoring System
(TPMS)
TPMS provides a warning if inflation pressure in
one or more tires is too low. It also uses a sym-
bol (called a telltale) that will flash for
60 seconds and then glow steadily if there is a
system malfunction.
TPMS uses sensors mounted in the tire valves to
check inflation pressure levels. When the vehicle
is moving at a speed of approximately 20 mph
(30 km/h) or faster, these sensors transmit infla-
tion pressure data to a receiver located in the
vehicle. If inflation pressure is too low, an indica-
tor symbol will illuminate in the instrument panel
and a text message will be displayed.
Symbol Explanation
The symbol illuminates to indicate
low tire inflation pressure.
If a malfunction occurs in the sys-
tem, the tire pressure warning sym-
bol will flash for approximately
1 minute and then remain illumi-
nated.
Each tire, including the spare (if provided), should
be checked monthly when cold and inflated to
the inflation pressure recommended by the vehi-
cle 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 pres-
sure 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 pressure.
Driving on a significantly under-inflated tire cau-
ses the tire to overheat and can lead to tire fail-
ure. 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 main-
tenance, and it is the driver's responsibility to
maintain correct tire pressure, even if under-infla-
tion has not reached the level to trigger illumina-
tion 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 mal-
function indicator is combined with the low tire
pressure telltale.
When the system detects a malfunction, the tell-
tale will flash for approximately one minute and
then remain continuously illuminated. This
sequence will continue upon subsequent vehicle
