170 SAFETY
The TPMS is not a substitute for proper tire mainte-
nance, and it is the driver’s responsibility to maintain
correct tire pressure using an accurate tire gauge, even
if underinflation has not reached the level to trigger illu-
mination of the Tire Pressure Monitoring System
Warning Light.
Seasonal temperature changes will affect tire pres-
sure, and the TPMS will monitor the actual tire pres-
sure in the tire.
Base System
This is the TPMS Warning Light located in the
instrument cluster.
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 the tires on your vehicle regularly 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 Warning Light.
TIRE PRESSURE MONITORING SYSTEM LOW
PRESSURE WARNINGS
The Tire Pressure Monitoring System Warning Light will
illuminate in the instrument cluster, an acoustic signal will
be activated, and the “Check left or right front/rear tire”
text message will display when one or more of the four
active road tire pressures are low. 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. The system will automatically update and the Tire
Pressure Monitoring Warning Light will extinguish once the
updated tire pressures have been received. The vehicle
may need to be driven for up to 20 minutes above 15 mph
(24 km/h) to receive this information.
CHECK TPMS WARNINGS
The Tire Pressure Monitoring System Warning Light will
flash on and off for 75 seconds and remain on solid when
a system fault is detected, an audible chime will be
activated and the “Service Tire Pressure Monitoring
System” text message will display. If the ignition is cycled,
this sequence will repeat providing the system fault still
exists. The Tire Pressure Monitoring System Warning Light
will turn off when the fault condition no longer exists.
A system fault can occur with any of the following
scenarios:
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.
Snow or ice around the wheels or wheel housings.
Using tire chains on the vehicle.
Using wheels/tires not equipped with TPMS sensors.
NOTE:
Your vehicle may be equipped with a compact spare wheel
and tire assembly.
The compact spare tire does not have a Tire Pressure
Monitoring System sensor. Therefore, the TPMS will not
monitor the tire pressure in the compact spare tire.
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, a chime will
sound and the Tire Pressure Monitoring System
Warning Light will still turn on due to the low tire.
However, after driving the vehicle for up to 20 minutes
above 15 mph (24 km/h), the Tire Pressure Monitoring
System Warning Light will flash on and off for
75 seconds and then remain on solid.
This occurs for each subsequent ignition cycle, a chime
will sound and the Tire Pressure Monitoring System
Warning Light will flash on and off for 75 seconds and
then remain on solid.
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 Monitoring System Warning 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.
