Vehicles With Compact Spare or Non-Matching Full Size
Spare
1. The compact spare tire or non-matching full size spare
tire does not have a tire pressure monitoring sensor.
Therefore, the TPMS will not monitor the pressure in the
spare tire.
2. If you install the compact or non-matching full size spare
tire in place of a road tire that has a pressure below the
low-pressure warning limit, a chime will sound and the
“TPMS Light” and “LOW TIRE PRESSURE” and "Inflate
to XX" messages will turn on upon the next ignition cycle.
3. After driving the vehicle for up to 20 minutes above
15 mph (24 km/h), the “TPMS Light” will flash on and off
for 75 seconds and then remain on solid.
4. For each subsequent ignition cycle, a chime will sound
and the “TPMS Light” will flash on and off for 75 seconds
and then remain on solid.
5. Once you repair or replace the original road tire and rein-
stall it on the vehicle in place of the compact spare or
non-matching full size spare, the TPMS will update auto-
matically and the “TPMS Light” will turn off, as long as no
tire pressure is below the low-pressure warning limit in
any of the four active road tires. 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.
Tire Pressure Monitoring System Operation
The Tire Pressure Monitoring System (TPMS) uses wireless
technology with wheel rim mounted electronic sensors to
monitor tire pressure levels. Sensors, mounted to each wheel
as part of the valve stem, transmit tire pressure readings to
the receiver module.
NOTE:
It is particularly important for you to check the tire pressure
in all of the tires on your vehicle monthly and to maintain the
proper pressure.
The TPMS consists of the following components:
• Receiver Module.
• Four Tire Pressure Monitoring sensors.
• Various Tire Pressure Monitoring System messages, which
display in the instrument cluster.
• Tire Pressure Monitoring Light.
