Base System
The Tire Pressure Monitor System (TPMS)
uses wireless technology with wheel rim
mounted electronic sensors to monitor tire pres-
sure 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 Tire Pressure Monitor System (TPMS) con-
sists of the following components:
1. Receiver Module
2. Four Tire Pressure Monitoring Sensors
3. Tire Pressure Monitoring Telltale Light
A tire pressure monitoring sensor is located in
the spare wheel if the vehicle is equipped with a
matching full size spare wheel and tire assem-
bly. The matching full size spare tire can be
used in place of any of the four road tires. A
low spare tire will not cause the "Tire Pressure
Monitoring Telltale Light" to illuminate or the
chime to sound while it is stored in the spare tire
location.
The "Tire Pressure Monitoring Telltale
Light" will illuminate in the instrument
cluster, a "Lo Tire" message will be
displayed in the odometer display at 3 second
intervals followed by the location(s) of the low
tire(s) (RR, LR, RF, LF) displayed for 3 second
intervals each. This sequence shall be repeated
for two complete cycles for each ignition "on"
cycle. Following the second cycle, the odometer
display shall revert back to the prior display
preceding the low tire message. An audible
chime will be activated 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 Telltale Light" and "Lo Tire"
message will extinguish once the updated tire
pressures have been received.
NOTE:
When filling warm tires, the tire pressure
may need to be increased up to an additional
4 psi (30 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) to receive
this information.
The "Tire Pressure Monitoring Telltale Light" will
flash on and off for 75 seconds, and will 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. A system
fault can occur by any of the following sce-
narios:
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.
