Check TPMS Warnings
The Tire Pressure Monitoring Telltale Light will
flash on and off for 75 seconds and remain on
solid when a system fault is detected. The
system fault will also sound a chime. If the
ignition key 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 with any of the following
scenarios:
1. Jamming due to electronic devices or driving
next to facilities emitting the same radio
frequencies as the TPM sensors.
2. Installing some form of aftermarket window
tinting that affects radio wave signals.
3. Snow or ice around the wheels or wheel
housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM
sensors.
NOTE:
Your vehicle is equipped with a compact
spare wheel and tire assembly.
1. The compact spare tire does not have a tire
pressure monitoring sensor. Therefore, the
TPMS will not monitor the tire 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 key cycle, a chime will sound and the
Tire Pressure Monitoring Telltale Light and
LOW TIRE message will still turn ON due to
the low tire.
3. However, after driving the vehicle for up to
10 minutes above 15 mph (24 km/h), the Tire
Pressure Monitoring Telltale Light will flash
on and off for 75 seconds and then remain on
solid.
4. For each subsequent ignition key cycle, a
chime will sound and the Tire Pressure Moni-
toring 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 tire, the TPMS will update
automatically and the Tire Pressure Monitor-
ing Telltale Light will turn OFF, as long as no
tire pressure is below the low-pressure warn-
ing limit in any of the four active road tires.
The vehicle may need to be driven for up to
10 minutes above 15 mph (24 km/h) in order
for the TPMS to receive this information.
Premium System — If Equipped
The 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.
NOTE:
It is particularly important for you to check
the tire pressure in all of your tires regularly
and to maintain the proper pressure.
The TPMS consists of the following compo-
nents:
• Receiver Module
• Four Tire Pressure Monitoring Sensors
• Three Trigger Modules (mounted in three of
the four wheel wells)
• Various Tire Pressure Monitoring System
Messages, which display in the instrument
cluster
• Tire Pressure Monitoring Telltale Light
Tire Pressure Monitoring Low Pressure
Warnings
The Tire Pressure Monitoring Telltale Light will
illuminate in the instrument cluster and an au-
dible chime will be activated when one or more
of the four active road tire pressures are low.
The audible chime will sound once every ignition
cycle for the first condition that it detects. In
addition, the instrument cluster will display a
"LOW TIRE" text message for a minimum of five
seconds and a graphic of the pressure value(s)
with the low tire(s) flashing.
