Tire Pressure Monitor
This vehicle may have a Tire
Pressure Monitor System (TPMS).
The Tire Pressure Monitor System
alerts you when a significant
reduction in pressure occurs in one
or more of your vehicle’s tires by
illuminating the low tire pressure
warning light on the instrument
cluster. The warning light will remain
on until the tire pressure is
corrected. The proper tire pressures
for your vehicle are listed on the
Tire and Loading Information label
located on the driver side center
pillar (B pillar). SeeVehicle Load
Limits on page 9‑10.
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.
Note:
The Tire Pressure Monitor
System 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.
