Your vehicle is equipped with a tire
pressure monitoring system (TPMS)
that turns on every time you start the
engine and monitors the pressure in
your tires while driving.
Each tire has its own pressure
sensor. If the air pressure of a tire
becomes signif icantly low, the
sensor in that tire immediately sends
a signal that causes the low tire
pressure/TPMS indicator in the
instrumental panel and the
appropriate tire position indicator on
thetirepressuremonitoronthe
multi-inf ormation display (see page)tocomeon. When the low tire pressure/TPMS
indicator is on, one or more of your
tires is signif icantly underinf lated.
The multi-inf ormation display also
shows a ‘‘CHECK TIRE PRESSURE’’
message (see page ). You should
stop and check your tires as soon as
possible, and inflate them to the
proper pressure as indicated on the
vehicle’s tire inf ormation placard.
Driving on a signif icantly under-
inf lated tire causes the tire to
overheat and can lead to tire failure.
Under-inf lation also reduces f uel
efficiency and tire tread life, and may
af f ect the vehicle’s handling and
stopping ability.
Becausetirepressurevariesby
temperature and other conditions,
the low tire pressure/TPMS
indicator may come on unexpectedly. For example, if you check and f ill
your tires in a warm area, then drive
in extremely cold weather, the tire
pressure will be lower than
measured and could be underinflated
and cause the low tire pressure/
TPMS indicator to come on. Or, if
youcheckandadjustyourtire
pressure in cooler conditions, and
drive into extremely hot conditions,
the tire may become overinf lated.
However, the low tire pressure/
TPMS indicator will not come on if
the tires are overinflated.
Refer to page for tire inflation
guidelines.
If there is a problem with the TPMS,
this indicator begins to f lash. It stops
flashing after approximately 1
minute, then stays on. You will also
see a ‘‘CHECK TPMS SYSTEM’’
message on the multi-information
display (see page ).
