Vehicle status messages in the multifunction display


Possible cause/consequence The Advanced TPMS is unable to monitor the tire inflation pressure due to: Ra nearby radio interference source Rthe on-board voltage is too low Rexcessive wheel sensor temperatures


Possible solution As soon as the causes of the malfunction have been removed, the Advanced TPMS becomes active again automatically after a few minutes driving.


G 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.
