WARNING (Continued)
the tires are rated for high-speed
operation, in excellent condition,
and set to the correct cold tire
inflation pressure for the
vehicle load.
Vehicles with 255/40ZR19 or 285/
35ZR19 size tires require inflation
pressure adjustment when driving
the vehicle at speeds of
160 km/h (100 mph) or higher. Set
the cold inflation pressure to the
maximum inflation pressure shown
on the tire sidewall,
or 300 kPa (44 psi), whichever is
lower. See the example following.
Return the tires to the
recommended cold tire inflation
pressure when high-speed driving
has ended. See Vehicle Load Limits
on page 910 and Tire Pressure on
page 1066.
Example:
The maximum load and inflation
pressure is molded on the tire
sidewall, in small letters, near the
rim flange. It will read something like
this: Maximum load
690 kg (1521 lbs) 300 kPa (44 psi)
Max. Press.
For this example, set the inflation
pressure for highspeed driving at
300 kPa (44 psi).
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 a
receiver 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 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.
