Never spin the tires in excess of the 35 mph (55 km/h) point
indicated on the speedometer.
Highway hazards
No matter how carefully you drive there’s always the possibility that you
may eventually have a flat tire on the highway. Drive slowly to the
closest safe area out of traffic. This may further damage the flat tire, but
your safety is more important.
If you feel a sudden vibration or ride disturbance while driving, or you
suspect your tire or vehicle has been damaged, immediately reduce your
speed. Drive with caution until you can safely pull off the road. Stop and
inspect the tires for damage. If a tire is under-inflated or damaged,
deflate it, remove wheel and replace it with your spare tire and wheel. If
you cannot detect a cause, have the vehicle towed to the nearest repair
facility or tire dealer to have the vehicle inspected.
Tire pressure monitoring system (TPMS)(if equipped)
When the tire pressure monitoring
system warning light is lit, one or
more of your tires is significantly
under-inflated. 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
information placard (label). 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. Even if your vehicle is equipped
with a tire pressure monitoring system, it is still important that you
manually check the inflation pressure of your tires regularly. Each tire,
including the spare, should be checked monthly when cold and set to the
recommended inflation pressure as specified on the vehicle placard
(label) and in the owner’s manual.
Note:The Tire Pressure Monitoring System (TPMS) monitors tire
pressure in each pneumatic tire. The pressure in each tire is dependent
upon several factors, one of them being the contained air temperature
(temperature of the air inside the tire). As the contained air temperature
increases, the tire pressure also increases. While driving in a normal
manner, a typical passenger tire inflation pressure may increase
approximately 2 to 4 psi (14 to 28 kPa) from a cold start situation. This
increase in tire pressure is due to an increase in the contained air

temperature. Contained air temperature is dependent upon several
factors such as rate of tire rotation, tire deflection, amount of braking,
etc. In similar manner, the tire pressure will decrease if the contained air
temperature decreases. For example, if the vehicle is stationary over
night with the outside temperature significantly lower than the daytime
temperature, the tire pressure may decrease approximately 3 psi (20.7
kPa) for a drop of 30° F (16.6° C) in ambient temperature. This lower
pressure value may be detected by the TPMS as being significantly lower
than the cold pressure indicated on your vehicles tire label, and activate
the TPMS warning for low tire pressure. If the low warning light is on,
visually check each tire to verify that no tire is flat. If one or more tires
are flat, repair of fix as necessary. If all tires appear to be inflated,
carefully drive the vehicle to the nearest location where air can be added
to the tires. Turn the ignition to the “off” position. Inflate all the tires to
the recommended cold pressure.
The system uses radio-frequency to monitor the tire pressure on all tires
excluding the spare tire. The sensors transmit the tire pressure readings
to the receiver module located in the vehicle. The receiver module then
electronically transmits the status to the message center. For more tire
warning information, refer to theMessage Centerin theDriver controls
chapter.
This device complies with part 15 of the FCC rules and with RS-210 of
Industry Canada. Operation is subject to the following two conditions:
(1) This device may not cause harmful interference, and (2) This device
must accept any interference received, including interference that may
cause undesired operation.
The tire pressure monitoring system is NOT a substitute for
manually checking tire pressure. The tire pressure should be
checked periodically (at least monthly) using a tire gauge, seeTire
inflation pressurein this chapter. Failure to properly maintain your
tire pressure could increase the risk of tire failure, loss of control,
vehicle rollover and personal injury.
