266 STARTING AND OPERATING
CAUTION!
After inspecting or adjusting the tire pressure, al-
ways reinstall the valve stem cap. This will prevent
moisture and dirt from entering the valve stem,
which could damage the Tire Pressure Monitoring
Sensor.
NOTE:
TPMS is not intended to replace normal tire care and
maintenance, or to provide warning of a tire failure or
condition.
TPMS should not be used as a tire pressure gauge
while adjusting your tire pressure.
Driving on a significantly under-inflated tire causes
the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency and tire
tread life, and may affect the vehicle's handling and
stopping ability.
TPMS is not a substitute for proper tire maintenance,
and it is the driver's responsibility to maintain correct
tire pressure using an accurate tire pressure gauge,
even if under-inflation has not reached the level to
trigger illumination of the TPMS Telltale Light.
Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in
the tire.

Base System

The TPMS uses wireless technology with wheel rim-
mounted electronic sensors to monitor tire pressure lev-
els. Sensors, mounted to each wheel as part of the valve
stem, transmit tire pressure readings to the Receiver
Module.
