Wipers Notes ! Do not operate the wipers when the

windshield is dry. Dust that accumulates on a windshield might scratch the glass and/ or damage the wiper blades when wiping occurs on a dry windshield. If it is necessary to operate the wipers in dry weather conditions, always operate the wipers with washer fluid.

! If the windshield wipers leave smears on the windshield after the car has been driven through an automatic car wash, then wax or other residue is on the windshield. Shortly after washing the car in an automatic car wash, clean the windshield with washer fluid.

X Switch on the ignition. X Turn the combination switch to the desired position, depending on the intensity of the rain.

i When the windshield wipers are switched

on and you stop the vehicle, the wipers operate more slowly.

Intermittent wiping Only switch on intermittent wiping under wet weather conditions or in the presence of precipitation. When you select intermittent wiping, the rain sensor is activated. The rain sensor sets a suitable wiping interval depending on the wetness of the sensor surface automatically. ! Do not leave windshield wipers on an intermittent setting when the vehicle is taken to an automatic car wash or during windshield cleaning. Windshield wipers will operate in the presence of water sprayed on the windshield, and windshield wipers may be damaged as a result.

! If you have set intermittent wiping, dirt on

the surface of the rain sensor or optical effects may cause the windshield wipers to wipe in an undesired fashion. This could then damage the windshield wiper blades or scratch the windshield. You should therefore switch off the windshield wipers when weather conditions are dry.

X Turn the combination switch to position

Ä or Å. After the initial wipe, pauses between wipes are controlled by the rain sensor automatically.

Intermittent wiping is interrupted when the vehicle is at a standstill and a door is opened. This protects persons getting into or out of the vehicle from being sprayed.

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. During severe operating conditions, e.g. stop- and-go traffic, the coolant temperature may rise close to 248‡ (120†), i.e close to the red zone of the temperature gauge. ! Excessive coolant temperature triggers a

warning in the multifunction display. The engine should not be operated with a coolant temperature above 248‡ (120†), i.e. in the red zone of the coolant temperature gauge. Doing so may cause serious engine damage which is not covered by the Mercedes-Benz Limited Warranty.

Tachometer The red marking on the tachometer (Y page 29) denotes excessive engine speed. ! Avoid driving at excessive engine speeds, as it may result in serious engine damage that is not covered by the Mercedes-Benz Limited Warranty.

To help protect the engine, the fuel supply is interrupted if the engine is operated within the red marking.

Outside temperature indicator The outside temperature indicator is on the bottom left-hand side of the instrument cluster (Y page 29). G Warning! The outside temperature indicator is not designed to serve as an ice-warning device and is therefore unsuitable for that purpose.
