Tire Pressure Monitoring Low Pressure Warnings
The Tire Pressure Monitoring System Warning Light
will illuminate in the instrument cluster and a
chime will sound when tire pressure is low in one or more
of the four active road tires. In addition, the instrument
cluster will display a low pressure text message and a
graphic showing the low tire pressure tire highlighted in a
different color.
Low Tire Indicator
Should this occur, you should stop as soon as possible and
inflate the tires with low pressure to the vehicle's recom-
mended cold placard pressure value. Once the system
receives the updated tire pressures, the system will auto-
matically update and the Tire Pressure Monitoring System
Warning Light will turn off. The vehicle may need to be
driven for up to 20 minutes above 15 mph (24 km/h) in
order for the TPMS to receive this information.
TPMS Warning
When a system fault is detected, the Tire Pressure Moni-
toring System Warning Light will flash on and off for 75
seconds and then remain on solid. The system fault will
sound a chime and also display a "Service Tire Pressure
Monitoring System" message in the instrument cluster for
approximately 5 seconds.
