“In case of emergency” section of this
manual.
TIRE PRESSURE
Tire Pressure Monitoring System
(TPMS)
This vehicle is equipped with the Tire
Pressure Monitoring System (TPMS). It
monitors tire pressure of all tires except
the spare. When the low tire pressure
warning light is lit, one or more of your
tires is significantly under-inflated. The
system also displays pressure of all tires
(except the spare tire) on the display
screen by sending a signal from a sensor
that is installed in each wheel.
The TPMS will activate only when the
vehicle is driven at speeds above 16 MPH
(26 km/h). Also, this system may not de-
tect a sudden drop in tire pressure (for
example a flat tire while driving).
For more details, refer to “Low tire pres-
sure warning light”in the “Instruments and
controls” section, “Tire pressure informa-
tion”in the “Monitor, climate, audio, phone
and voice recognition systems” section,
“Tire Pressure Monitoring System
(TPMS)” in the “Starting and driving” sec-
tion, and “Flat tire” in the “In case of emer-
gency” section.
Tire inflation pressure
Check the tire pressures (including the
spare) often and always prior to long dis-
tance trips. The recommended tire pres-
sure specifications are shown on the
F.M.V.S.S./C.M.V.S.S. certification label
or the Tire and Loading Information label
under the “Cold Tire Pressure” heading.
The Tire and Loading Information label is
affixed to the driver side center pillar. Tire
pressures should be checked regularly
because:
● Most tires naturally lose air over time.
● Tires can lose air suddenly when
driven over potholes or other objects
or if the vehicle strikes a curb while
parking.
The tire pressures should be checked
when the tires are cold. The tires are
considered COLD after the vehicle has
been parked for 3 or more hours, or driven
less than 1 mile (1.6 km) at moderate
speeds.
Incorrect tire pressure, including un-
der inflation, may adversely affect
tire life and vehicle handling.
