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 Monitoring Telltale 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 informa-
tion.
Service TPMS Warning
When a system fault is detected, the "Tire Pressure Moni-
toring Telltale 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 Telltale Light" will turn off when the fault
condition no longer exists. A system fault can occur due to
any of the following:
1. Jamming due to electronic devices or driving next to
facilities emitting the same radio frequencies as the
TPMS sensors.
2. Installing some form of aftermarket window tinting that
affects radio wave signals.
3. Lots of snow or ice around the wheels or wheel hous-
ings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPMS sensors.
Vehicles With Compact Spare
1. The compact spare tire does not have a tire pressure
monitoring sensor. Therefore, the TPMS will not moni-
tor 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, a chime will sound and
the "TPMS Telltale 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 Telltale 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 Telltale 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 Telltale Light" will turn
