(-7°C) will decrease the tire pressure to
approximately 24 psi (165 kPa). This tire
pressure is low enough to turn on the “Tire
Pressure Monitoring Warning Light.” Driving
the vehicle may cause the tire pressure to
rise to approximately 28 psi (193 kPa), but
the “Tire Pressure Monitoring Telltale Light”
will still be on. In this situation, the “Tire
Pressure Monitoring Warning Light” will turn
off only after the tires are inflated to the
vehicle’s recommended cold placard pres
-
sure value.
Insufficient Tire Pressure Indication
If an insufficient pressure value is detected
on one or more tires, the warning light in
the instrument cluster will display alongside
the dedicated messages, the system will
highlight the tire or tires with insufficient
pressure graphically, and an acoustic signal
will be emitted.
In this case, stop the vehicle, check the
inflation pressure of each tire, and inflate the
necessary tire or tires to the correct cold
inflation pressure value, shown on the
display or in the dedicated TPMS menu.
TPMS Temporarily Disabled — TPMS Check
Message
When a system fault is detected, the “Tire
Pressure Monitoring Telltale Light” will flash
on and off for 75 seconds, and then remain
on solid. The system fault will also sound a
chime. If the ignition is cycled, this
sequence will repeat, provided that 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 due to any of the following:
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.
Accumulation of snow or ice around the
wheels or wheel housings.
Using tire chains on the vehicle.
Using wheels/tires not equipped with
TPMS sensors.
After the punctured tire has been repaired
with the original tire sealant contained in the
Tire Repair Kit, the previous condition must
be restored so that the warning light is off
during normal driving.
TPMS Deactivation
The TPMS can be deactivated by replacing
all four wheel and tire assemblies (road tires)
with wheel and tire assemblies that do not
have TPMS Sensors, such as when installing
winter wheel and tire assemblies on your
vehicle.
CAUTION!
The TPMS has been optimized for the
original equipment tires and wheels.
TPMS pressures and warning have been
established for the tire size equipped on
your vehicle. Undesirable system opera
-
tion or sensor damage may result when
using replacement equipment that is not
of the same size, type, and/or style. The
TPM sensor is not designed for use on
aftermarket wheels and may contribute
to a poor overall system performance or
sensor damage. Customers are encour
-
aged to use OEM wheels to assure proper
TPM feature operation.
Using aftermarket tire sealants may
cause the Tire Pressure Monitoring
System (TPMS) sensor to become inop
-
erable. After using an aftermarket tire
sealant it is recommended that you take
your vehicle to your authorized dealer to
have your sensor function checked.
After inspecting or adjusting the tire
pressure always reinstall the valve stem
cap. This will prevent moisture and dirt
from entering the valve stem, which
could damage the TPMS sensor.
