Possible cause/consequence
Possible solution
Tire Pressure Monitor
Currently Unavailable
The Advanced TPMS is unable to monitor
the tire inflation pressure due to:

a nearby radio interference source


the on-board voltage is too low


excessive wheel sensor temperatures
As soon as the causes for the malfunction are no longer present,
the Advanced TPMS automatically becomes active again after a
few minutes driving.
Warning!
G
Do not drive with a flat tire. A flat tire affects
the ability to steer or brake the vehicle. You
may lose control of the vehicle. Continued
driving with a flat tire will cause excessive
heat build-up and possibly a fire.
Follow recommended tire inflation pres-
sures.
Do not underinflate tires. Underinflated tires
wear excessively and/or unevenly, adverse-
ly affect handling and fuel economy, and are
more likely to fail from being overheated. Do
not overinflate tires. Overinflated tires can
adversely affect handling and ride comfort,
wear unevenly, increase stopping distance,
and result in sudden deflation (blowout) be-
cause they are more likely to become punc-
tured or damaged by road debris, potholes
etc.
