302 STARTING AND OPERATING
The "Tire Pressure Monitoring Telltale Light" will
illuminate in the instrument cluster, and an audible
chime will be activated when one or more of the
four active road tire pressures are low. Should this occur,
you should stop as soon as possible, check the inflation
pressure of each tire on your vehicle, and inflate each tire to
the vehicle's recommended cold placard pressure value.
The system will automatically update and the "Tire Pres-
sure Monitoring Telltale Light" will extinguish once the
updated tire pressures have been received. The vehicle may
need to be driven for up to 20 minutes above 15 mph
(24 km/h) to receive this information.
The "Tire Pressure Monitoring Telltale Light" will flash
on and off for 75 seconds, and remain on solid when a
system fault is detected. The system fault will also sound
a chime. If the ignition key is cycled, this sequence will
repeat, providing the system fault still exists. The "Tire
Pressure Monitoring Telltale Light" will turn off when
the fault condition no longer exists. A system fault can
occur by any of the following scenarios: 1) Jamming due
to electronic devices or driving next to facilities emitting
the same radio frequencies as the TPM sensors; 2) Install-
ing some form of aftermarket window tinting that affects
radio wave signals; 3) Lots of snow or ice around the
wheels or wheel housings; 4) Using tire chains on the
vehicle; 5) Using wheels/tires not equipped with TPM
sensors.
NOTE: Your vehicle is equipped with a non-matching
full size spare wheel and tire assembly.
1. This spare tire does not have a tire pressure monitor-
ing sensor. Therefore, the TPMS will not monitor the tire
pressure in the spare tire.
2. If you install the full size spare tire in place of a road
tire that has a pressure below the low-pressure warning
limit, upon the next ignition key cycle a chime will sound
and the "TPM Telltale Light" will still turn ON due to the
low tire.
