This vehicle may have a Tire Pressure Monitor System (TPMS).
The Tire Pressure
Monitor alerts you when
a significant reduction in
pressure occurs in one or
more of the vehicle’s tires
by illuminating the low tire
pressure warning light on
the instrument cluster.
If the warning light comes on, stop as soon as possible and inflate the tires to the recommended pressure shown on the tire loading information label located on the driver side center pillar (B pillar). See Loading the Vehicle. The warning light will remain on until the tire pressure is corrected.
You may notice during cooler conditions that the low tire pressure warning light will appear when the vehicle is first started and then turn off as you drive. This may be an early indicator that your tire pressures are getting low and the tires need to be inflated to the proper pressure.
The Tire Pressure Monitor can alert you about low tire pressure, but it does not replace normal monthly tire maintenance. It is the driver’s responsibility to maintain correct tire pressures.
