SAFETY 163
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 TPMS
Warning Light will flash on and off for 75
seconds and then remain on solid. The system
fault will also sound a chime. In addition, the
instrument cluster will display a "SERVICE TIRE
PRESSURE SYSTEM" message for a minimum of
five seconds and then display dashes (--) in
place of the pressure value to indicate which
sensor is not being received.
If the ignition is cycled, this sequence will
repeat, providing the system fault still exists. If
the system fault no longer exists, the TPMS
Warning Light will no longer flash, and the
“SERVICE TIRE PRESSURE SYSTEM” message
will no longer display, and a pressure value will
display in place of the dashes. 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 does not have a Tire Pressure
Monitoring sensor. Therefore, the TPMS
will not monitor the pressure in the
compact 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, upon the next ignition cycle,
the TPMS Warning Light will remain on and
a chime will sound. In addition, the graphic
in the instrument cluster will still display a
different color pressure value and an
"Inflate to XX" message.
3. After driving the vehicle for up to
20 minutes above 15 mph (24 km/h), the
TPMS Warning Light will flash on and off for
75 seconds and then remain on solid. In
addition, the instrument cluster will display
a “Service Tire Pressure System” message
for five seconds and then display dashes (--)
in place of the pressure value.
4. For each subsequent ignition cycle, a chime
will sound, the TPMS Warning Light will
flash on and off for 75 seconds and then
remain on solid, and the instrument cluster
will display a “SERVICE TIRE PRESSURE
SYSTEM” message for five seconds and
then display dashes (--) in place of the pres-
sure value.
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, the TPMS will update automatically. In
addition, the TPMS Warning Light will turn
off and the graphic in the instrument cluster
will display a new pressure value instead of
dashes (--), 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.
