Caution Tire Defect
Check Tires
Possible causes/consequences and M Solutions The tire inflation pressure is too low in at least one tire. or The tire inflation pressures of the individual tires differ from each other significantly. The tire inflation pressure values are shown in the multifunction display. X Check and correct tire inflation pressure as required
(Y page 232).
X Restart the Advanced TPMS (Y page 236). At least one tire is deflating. The respective tire is indicated in the multifunction display. X Carefully bring the vehicle to a halt, avoiding abrupt
steering and braking maneuvers.
X If necessary, change the wheel (Y page 317). The tire inflation pressure in at least one tire is significantly below the reference value. The respective tire is indicated in the multifunction display. X Carefully bring the vehicle to a halt, avoiding abrupt
steering and braking maneuvers.
X Check and adjust tire inflation pressure as required. X If necessary, change the wheel (Y page 317).
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.

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.
