152 SAFETY
Check TPMS Warnings
The Tire Pressure Monitoring 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 a proper
text message will be displayed. If the ignition
key is cycled, this sequence will repeat
providing the system fault still exists. The Tire
Pressure Monitoring Warning 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 can be equipped with either a Tire
Service Kit, a compact spare tire or a regular
size spare tire (with or without original TPMS
sensor).
1. Tire Service Kit (original tire sealant – if
equipped): After fixing the punctured tire
with original tire sealant, the original
situation will be restored, so system will
turn off the telltale during the normal drive.
2. Compact Spare Tire – if equipped: The
compact spare wheel is not equipped with a
TPMS sensor. So when mounted, during the
normal drive the system will turn on the
telltale (flashing for approximately
75 seconds then remains solid). This
condition persists until a wheel equipped
with original TPMS sensor has been
mounted on the vehicle.
3. Regular size spare tire (not equipped with
TPMS sensor): When mounted, during the
normal drive the system will turn on the
telltale (flashing for approximately
75 seconds then remains solid). This
condition persists until a wheel equipped
with original TPMS sensor has been
mounted on the vehicle. Then the system
will be restored and the telltale will turn off
during the normal drive.
4. Regular size spare tire (equipped with TPMS
sensor): When mounted, the telltale will
turn off during the normal drive.
5. In all the above cases, please check the
replacement tire inflation pressure before
driving your vehicle.
6. In case of tire replacement, if the vehicle is
driven for short periods of time, then the
system can take a while to be restored.
NOTE:
For a correct Tire Pressure Monitoring behavior,
please wait for about 20 minutes in key-off
during each tire substitution.
