Tire Pressure Monitoring Display
Should a low tire condition occur on any of the
four active road tire(s), you should stop as soon
as possible and inflate all tires that are flashing
on the graphic display to the vehicle's recom-
mended cold placard pressure value. The sys-
tem will automatically update, the "LOW TIRE"
text message will no longer be displayed, the
graphic display of the pressure value(s) will stop
flashing, and the Tire Pressure Monitoring Light
will extinguish once the updated tire pressure(s)
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
10 minutes above 15 mph (24 km/h) to receive
this information.
Service TPMS Message
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. The instru-
ment cluster will display a "SERVICE TPM SYS-
TEM" message for a minimum of five seconds.
This text message is then followed by a graphic
display, with "- -" in place of the pressure val-
ue(s) indicating which Tire Pressure Monitoring
Sensor(s) is not being received.
Tire Pressure Monitoring Display
If the ignition key is cycled, this sequence will
repeat, providing the system fault still exists. If
the system fault no longer exists, the Tire Pres-
sure Monitoring Telltale Light will no longer flash,
the "SERVICE TPM SYSTEM" text message will
not be present, and a pressure value will be
displayed instead of dashes. 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.
The instrument cluster will also display a "SER-
VICE TPM SYSTEM" message for a minimum
of five seconds when a system fault related to
an incorrect sensor location fault is detected. In
this case, the "SERVICE TPM SYSTEM" mes-
sage is then followed with a graphic display with
pressure values still shown. This indicates that
the pressure values are still being received from
the TPM sensors but they may not be located in
the correct vehicle position. The system still
needs to be serviced as long as the "SERVICE
TPM SYSTEM" message is displayed.
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.
