Tires 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 465). 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. Symbol messages
