The TPMS is unable to monitor the tire
inflation pressure due to a nearby radio
interference source.
As soon as the causes of the malfunction have
been removed, the TPMS becomes active again
automatically after a few minutes driving.

Warning!
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.
G
Warning!
Follow recommended tire inflation pressures.
Do not underinflate tires. Underinflated tires wear excessively and/or unevenly, adversely 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) because they are more likely to become punctured or damaged by road debris, potholes etc.
