tion pressure label. (If your vehicle has tires
of a different size than the size indicated on
the vehicle placard or tire inflation pressure la-
bel, you should determine the proper tire infla-
tion pressure for those tires.)
As an added safety feature, your vehicle
has been equipped with a tire pressure
monitoring system (TPMS) that illumi-
nates 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 over-
heat 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 substi-
tute for proper tire maintenance, and it is
the driver’s responsibility to maintain cor-
rect 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 prop-
erly. The TPMS malfunction indicator is
combined with the low tire pressure tell-
tale. When the system detects a malfunc-
tion, the telltale will flash for approxi-
mately one minute and then remain con-
tinuously illuminated. This sequence will
continue
upon
subsequent
vehicle
start-ups as long as the malfunction ex-
ists. When the malfunction indicator is il-
luminated, the system may not be able to
detect or signal low tire pressure as in-
tended. TPMS malfunctions may occur for
a variety of reasons, including the instal-
lation of replacement or alternate tires or
wheels on the vehicle 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.
Additional information
O
The TPMS does not monitor the tire
pressure of the spare tire.
O
The TPMS will activate only when the ve-
hicle is driven at speeds above 16 MPH
(25 km/h). Also, this system may not de-
tect a sudden drop in tire pressure (for
example a flat tire while driving).
O
The low tire pressure warning light does
not automatically turn off when the tire
pressure is adjusted. After the tire is in-
flated 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.
O
Tire pressure rises and falls depending
on the heat caused by the vehicle’s op-
eration 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 illuminate. If
the warning light illuminates in low am-
bient temperature, check the tire pres-
sure for all four tires.
O
You can also check the pressure of all
tires (except the spare tire) on the display
screen. The order of the tire pressure fig-
ures displayed on the screen does not
correspond with the actual order of the
tire position. See “Tire pressure informa-
tion” in the “4. Display screen, heater, air
conditioner and audio system” section.

pressure warning light” in the “2. Instru-
ments and controls” section and “Tire pres-
sure monitoring system (TPMS)” in the “6.
In case of emergency” section.
