SAFETY 119
shown in the "Inflate to XX" message. Once the
system receives the updated tire pressures, the
system will automatically update and the “Tire
Pressure Monitoring Light” will turn off.
NOTE:
When filling warm tires, the tire pressure may
need to be increased up to an additional 4 psi
(28 kPa) above the recommended cold placard
pressure in order to turn the Tire Pressure Moni-
toring Light 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.
Service TPMS Warning
When a system fault is detected, the “Tire
Pressure Monitoring Light” will flash on and off
for 75 seconds and then remain on solid. The
system fault will also sound a chime. If the
ignition is cycled, this sequence will repeat,
providing the system fault still exists. The “Tire
Pressure Monitoring Light” will turn off when the
fault condition no longer exists. A system fault
can occur due to any of the following:
Jamming due to electronic devices or driving
next to facilities emitting the same radio
frequencies as the TPMS sensors.
Installing some form of aftermarket window
tinting that affects radio wave signals.
Lots of snow or ice around the wheels or
wheel housings.
Using tire chains on the vehicle.
Using wheels/tires not equipped with TPMS
sensors.
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 reinstall it on the vehicle in place of
the compact spare or non-matching full size
spare, the TPMS will update automatically
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.
