Understanding the Vehicle
Tire Pressure Monitoring
System (TPMS)
The Tire Pressure Monitoring System
(TPMS) will warn the driver of a low
tire pressure according to the vehicle
recommended cold pressure indicated
on the table "Tire Inflation Pressure" in
section "Technical Specifications" and
on the label applied on the bottom of
driver's side door.
Tire pressure should always be set
based on cold inflation tire pressure. The
cold tire inflation pressure must not
exceed the maximum inflation pressure
molded into the tire sidewall.
Check "Tires - General Information" in
this section for information on how to
much inflate the tires.
The tire pressure will also increase as
the vehicle is driven - this is normal and
there is no adjustment required when
this occurs.
To check the current pressure status of
the tires, consult My Car menu on the
MIA display (see "Functions of My Car
Menu on MIA" in section "Instruments
and Controls").
The TPMS will warn the driver of a low
tire pressure if the tire pressure falls
below the low-pressure warning limit for
any reason, including low temperature
effects and natural pressure loss of the
tire.
The TPMS will continue to warn the
driver of low tire pressure as long as
the condition persists and will not turn
off until the tire pressure is equal or
above the recommended cold inflation
pressure. Once the low tire pressure
warning light illuminates, you
must increase the tire pressure to the
recommended cold inflation pressure in
order for the TPMS light to turn off.
The system will automatically update
and the TPMS light will turn off once
the system acquires the correct tire
pressure.
The vehicle may need to be driven for up
to 20 minutes above 15 MPH (25 km/h)
in order for the TPMS to acquire and
process the updated setting.
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.
