Possible causes/consequences and X Solutions At least one sensor is defect (e.g. battery is empty). The respective tire is indicated by – – instead of the tire inflation pressure in the multifunction display. X Have the Advanced TPMS checked at an authorized

Mercedes-Benz Center.

X Have the wheel sensors installed at an authorized

Mercedes-Benz Center.

X Have the wheel sensors installed at an authorized

Mercedes-Benz Center.

The Advanced TPMS cannot monitor the tire inflation pressure due to a nearby radio interference source or insufficient power supply. As soon as the causes of the malfunction have been rectified, the Advanced TPMS becomes active again automatically after a few minutes of driving. 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 377).

X Restart the Advanced TMPS (Y page 380). 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

Display messages Check Tires

Possible causes/consequences and X Solutions 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.

system checked at an authorized Mercedes-Benz Center.

G Warning! Do not spill antifreeze on hot engine parts. Antifreeze contains ethylene glycol which may burn if it comes into contact with hot engine parts. You could be seriously burned.

! Do not ignore the low engine coolant level warning. Extended driving with the message

and symbol displayed may cause serious engine damage not covered by the Mercedes-Benz Limited Warranty. Do not drive without sufficient amount of coolant in the cooling system. The engine will overheat causing major engine damage.

Steam from an overheated engine can cause serious burns which can occur just by opening the engine hood. Stay away from the engine if you see or hear steam coming from it. Stop the vehicle in a safe location away from other traffic. Turn off the engine, get out of the vehicle and do not stand near the vehicle until the engine has cooled down.
