SAFETY 237
NOTE:
It is particularly important for you to check the tire
pressu
re 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 System sensors
Tire Pressure Monitoring System Light
TIRE PRESSURE MONITORING SYSTEM LOW
PRESSURE WARNINGS
The Tire Pressure Monitoring System
Light will illuminate in the instrument
cluste
r, a “LOW TIRE PRESSURE”
message will display in the instrument
cluster, an "Inflate to XX" message will be displayed
and a chime will sound when tire pressure is low in
one or more of the four active road tires. 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 as
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 System Light will turn off.
NOTE:
When filling warm tires, the tire pressure may need
to be i
ncreased up to an additional 4 psi (28 kPa)
above the recommended cold placard pressure in
order to turn the Tire Pressure Monitoring System
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 System 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 System 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 S
ize Spare
1. The compact spare tire or non-matching full
size spare tire does not have a Tire Pressure
Monitoring System 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 r
einstall 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.
