Vehicle Care
at speeds of 160 km/h (100 mph) or
higher. Set the cold inflation
pressure to 20 kPa (3 psi) above the
recommended cold tire pressure
shown on the Tire and Loading
Information label.
Vehicles with 245/45R18 Conti 96H
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 20 kPa (3 psi) above the
recommended cold tire pressure
shown on the Tire and Loading
Information label.
Vehicles with 235/50R18 97V 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 20 kPa (3 psi) above the
recommended cold tire pressure
shown on the Tire and Loading
Information label.
Vehicles with 245/40R19 94W 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 20 kPa (3 psi) above the
recommended cold tire pressure
shown on the Tire and Loading
Information label.
Return the tires to the
recommended cold tire inflation
pressure when high-speed driving
has ended. See

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.
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
