Control 0193.
Tire Pressure Monitor
This vehicle may have a Tire Pressure
Monitor System (TPMS).
The low tire pressure warning light
alerts to a significant loss in pressure
of one of the vehicle's tires. If the
warning light comes on, stop as soon
as possible and inflate the tires to the
recommended pressure shown on the
Tire and Loading Information label.
See Vehicle Load Limits 0176. The
warning light will remain on until the
tire pressure is corrected.
The low tire pressure warning light
may come on in cool weather when
the vehicle is first started, and then
turn off as the vehicle is driven. This
may be an early indicator that the tire pressures are getting low and the tires
need to be inflated to the proper
pressure.
The TPMS does not replace normal
monthly tire maintenance. Maintain
the correct tire pressures.
See
Tire Pressure Monitor System
