Suggested solution 왘 Bring the vehicle to a halt, avoiding
abrupt steering and braking maneuvers. Observe the traffic situation around you. 왘 Take note of the messages in the multi-
function display.
The warning lamp goes out once the tire in- flation pressure monitor has been reactivat- ed after the tire inflation pressures have been corrected.
Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehi- cle’s handling and stopping ability. Each tire, including the spare, should be checked monthly when cold and set to the recom- mended inflation pressure as specified in the vehicle placard and owner’s manual.
The recommended tire inflation pres- sures for your vehicle can be found on the tire placard on the driver's door B-pillar or, if available, the inside of the fuel filler flap, not in the owner’s manual.
Warning!
When the tire inflation pressure monitoring system warning light is lit, one or more of your tires is significantly under-inflated. You should stop and check your tires as soon as possible, and inflate them to the proper pressure as indicated on the vehicle’s tire in- formation placard. Driving on a significantly under-inflated tire causes the tire to over- heat and can lead to tire failure.

Vehicle status messages in the multi- function display
Warning and malfunction messages ap- pear in the multifunction display located in the instrument cluster. Certain warning and malfunction messag- es are accompanied by an audible signal. Address these messages accordingly and follow the additional instructions given in this Operator’s Manual. Selecting the vehicle status message memory menu in the control system (컄 page 137) displays both cleared and uncleared messages. High-priority messages appear in the mul- tifunction display in red color.
Certain messages of high priority cannot be cleared from the multifunction display using the reset button J (컄 page 134) or button j, k, ÿ, or è on the multifunction steering wheel (컄 page 138). Other messages of high priority and mes- sages of less immediate priority can be cleared from the multifunction display us- ing the reset button J or button j, k, ÿ, or è on the multifunction steering wheel. They are then stored in the vehicle status message memory (컄 page 153). Remember that clearing a message will only make the message dis- appear. Clearing a message will not cor- rect the condition that caused the message to appear.

Possible cause The coolant is too hot.
Practical hints What to do if …?
Possible solution 왘 Stop the vehicle and turn off the engine. 왘 Only start the engine again after the mes-
sage disappears. You could otherwise damage the engine.
During severe operating conditions, e.g. stop-and-go traffic, the coolant tem- perature may rise close to 248°F (120°C).
The engine should not be operated with the coolant temperature above 248°F (120°C). Doing so may cause serious engine damage which is not covered by the Mercedes-Benz Limited Warranty.

왔 Replacing bulbs Safe vehicle operation depends on proper exterior lighting and signaling. It is there- fore essential that all bulbs and lamp as- semblies are in good working order at all times. Correct headlamp adjustment is extremely important. Have headlamps checked and readjusted at regular intervals and when a bulb has been replaced. See your autho- rized Mercedes-Benz Center for headlamp adjustment.
If the headlamps or front fog lamps are fogged up on the inside as a result of high humidity, driving the vehicle a dis- tance with the lights on should clear up the fogging.
