Vehicle Care 357
Vehicles w
ith tire sizes listed in the High Speed Operation Inflation Pressures table require inflation pressure adjustment when driving the vehicle at speeds
o
f 160 km/h (100 mph) or higher. Set the cold tire inflation pressure to the corresponding value in the table for the tire size on the vehicle.
High Speed Operation Inflation Pressures
Tire Size Cold Inflation Pressure kPa (psi)
275/50R22 111H 270 kPa (39 psi)
285/40R24 112H 290 kPa (42 psi)
Return the tires to the recommended cold tire inflation pressure when high-speed driving has ended. See Vehicle Load Limits 3 191 and Tire Pressure 3 355.
Tire Pressure Monitor System
The Tire Pressure Monitor System (TPMS) uses
radio and sensor technology to check tire
pressure levels. The TPMS sensors monitor
the air pressure in your tires and transmit
tire pressure readings to areceiver located in
the vehicle.
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 alow 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 asignificantly
under-inflated tire causes the tire to overheat
and can lead to tire failure. Under-inflation
also reduces energy 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.
Your vehicle has also been equipped with
a TPMS malfunction indicator to indicate when
the system is not operating properly. The TPMS
malfunction indicator is combined with the
low tire pressure telltale. When the system
detects a malfunction, the telltale will flash for
