Tire Pressure Monitoring
System
í
The tire pressure monitoring system
(TPMS) monitors the pressure for each
tire.
If tire pressure is too low in one or more
tires, the system will inform the drive r via
the warning light in the instrument panel
and by the warning beep sound.
The tire pressure sensors installed on each
wheel send tire pressure data by radio
signal to the receiver unit in the vehicle.
Tire pressure sensors
NOTE
When the ambient temperature is low
due to seasonal changes, tire
temperatures are also lower. If the tire
temperature lowers, the air pressure
lowers as well, and the TPMS warning
light illuminates more frequently.
Inspect the tire pressure daily before
driving, and check the tire pressures
monthly with a tire pressure gauge.
When checking the tire pressures, use
of a digital tire pressure gauge is
recommended.
TPMS does not alleviate your need to
check the pressure and condition of all
four tires before you drive each day.
CAUTION
l
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.
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.
