SAFETY
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 TPM 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 — If Equipped
1. The compact spare tire does not have a Tire
Pressure Monitoring System sensor.
Therefore, the TPMS will not monitor the
pressure in the compact spare tire.
2. If you install the compact 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.
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 TPM
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 TPM SYSTEM" message for five
seconds and then display dashes (- -) in place
of the pressure value.
5. Once you repair or replace the original road tire
and reinstall it on the vehicle in place of the
compact spare, the TPMS will update automat-
ically. 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.
TIRE PRESSURE MONITORING SYSTEM LOW
PRESSURE WARNINGS
The TPMS Warning Light will illuminate in
the instrument cluster and a chime will
sound when tire pressure is low in one or
more of the four active road tires. In
addition, the instrument cluster will display an
"Inflate to XX" message and a graphic showing the
pressure values of each tire with the low tire
pressure values in a different color.
Tire Pressure Monitoring System
Should this occur, you should stop as soon as
possible and inflate the tires with low pressure
(those in a different color in the instrument cluster
graphic) to the vehicle's recommended cold
placard pressure value as shown in the
"Inflate to XX" message.
