Additional information:
● The TPMS does not monitor the tire
pressure of the spare tire.
● TheTPMS will activate only whenthe vehicle
is driven at speeds above 16 MPH (25
km/h). Also, this system may not detect a
sudden drop in tire pressure (for example a
flat tire while driving).
● The low tire pressure warning light does not
automatically turn off when the tire pressure
is adjusted. After the tire is inflated to the
recommended pressure,the vehicle must be
driven at speeds above 16 MPH (25 km/h)
to activate the TPMS and turn off the low tire
pressure warning light. Use a tire pressure
gauge to check the tire pressure.
● Tire pressure rises and falls depending on
the heat caused by the vehicle’s operation
and the outside temperature. Low outside
temperature can lower the temperature of
the air inside the tire which can cause a
lower tire inflation pressure. This may cause
the low tire pressure warning light to illumi-
nate. If the warning light illuminates in low
ambient temperature, check the tire pres-
sure for all four tires.
● The Tire and Loading Information label (also
referred to as the vehicle placard or tire
inflation pressure label) is located in the
driver’s door opening.
● You can also check the pressure of all tires
(except the spare tire) on the display screen
(if so equipped). The order of the tire pres-
sure figures displayed on the screen does
not correspond with the actual order of the
tire position. See “Tire pressure information”
in the “Monitor, climate, audio, phone and
voice recognition systems ” section.
For additional information, see “Low tire pressure
warning light” in the “Instruments and controls”
section and “Tire pressure monitoring system
(TPMS)” in the “In case of emergency” section.
WARNING
● If the low tire pressure warning light
illuminates while driving, avoid sudden
steering maneuvers or abrupt braking,
reduce vehicle speed, pull off the road
to a safe location and stop the vehicle
as soon as possible. Driving with under-
inflated tires may permanently damage
the tires and increase the likelihood of
tire failure. Serious vehicle damage
could occur and may lead to an acci-
dent and could result in serious per-
sonal injury. Check the tire pressure for
all four tires. Adjust the tire pressure to
the recommended COLD tire pressure
shown on the Tire and Loading Informa-
tion label to turn the low tire pressure
warning light OFF. If you have a flat tire,
replace it with a spare tire as soon as
possible. (See “Flat tire”in the “In case
of emergency” section for changing a
flat tire.)
