High Speed Operation
{CAUTION:
Driving at high speeds, 100 mph (160 km/h) or
higher, puts an additional strain on tires.
Sustained high-speed driving causes
excessive heat build up and can cause sudden
tire failure. You could have a crash and you or
others could be killed. Some high-speed rated
tires require in ation pressure adjustment for
high speed operation. When speed limits and
road conditions are such that a vehicle can be
driven at high speeds, make sure the tires are
rated for high speed operation, in excellent
condition, and set to the correct cold tire
in ation pressure for the vehicle load.
If you will be driving at high speeds, speeds of 100 mph
(160 km/h) or higher, where it is legal, set the cold
in ation pressure to the maximum in ation pressure
shown on the tire sidewall, or 38 psi (265 kPa), whichever
is lower. See the example following. When you end this
high-speed driving, return the tires to the cold in ation
pressure shown on the Tire and Loading Information
label. SeeLoading Your Vehicle on page 4-30.Example:
You will nd the maximum load and in ation pressure
molded on the tire’s sidewall, in small letters, near
the rim ange. It will read something like this: Maximum
load 690 kg (1521 lbs) 300 kPa (44 psi) Max. Press.
For this example, you would set the in ation pressure for
high-speed driving at 38 psi (265 kPa).
Tire Pressure Monitor System
The Tire Pressure Monitor (TPM) system uses radio and
sensor technology to check tire pressure levels. If your
vehicle has this feature, sensors are mounted on each
tire and wheel assembly, except for the compact spare
tire and wheel. Tire pressure readings are sent to a
receiver located in the vehicle once every 60 seconds
while the vehicle is being driven, and once every
60 minutes if the vehicle is stationary for more than
15 minutes.
Using the Driver Information Center (DIC), tire pressure
levels may be viewed by the driver. For additional
information and details about the DIC operation and
displays seeDIC Controls and Displays on page 3-74
andDIC Warnings and Messages on page 3-78.
