which all passenger car tires must meet under the Federal Motor Vehicle
Safety Standard No. 109. Grades B and A represent higher levels of
performance on the laboratory test wheel than the minimum required by
law.
The temperature grade for this tire is established for a tire that
is properly inflated and not overloaded. Excessive speed,
underinflation, or excessive loading, either separately or in
combination, can cause heat buildup and possible tire failure.
SERVICING YOUR TIRES
Low tire warning (if equipped)
The low tire warning system is designed to detect a significant loss of
inflation in any one of your tires on your vehicle. The system uses the
Anti-lock brake wheel speed sensors to detect a change in wheel speed
due to tire deflation.
When a tire loses inflation, the low
tire warning system detects the
change and illuminates the low tire
warning indicator light as shown.
If the light remains on while driving,
check the tire pressure refer to “Checking the tire pressure” in this
chapter. The low tire warning indicator light will also illuminate when
using a temporary spare, refer to “Changing the tires” in this chapter.
The low tire warning system may not detect an under-inflated
tire under all conditions and is not a substitute for manually
checking tires regularly for proper inflation.
The low tire warning system should be reset whenever new tires
are installed, rotated or tire pressures are changed.
To reset the system, turn the
ignition to the ON position, press
and hold the “TIRE RESET” switch
for three seconds. The low tire
warning indicator light will flash
three times as the low tire warning
system begins to initialize. The
