WARNING ‑ Risk of fire and injury from windshield washer concentrate

Windshield washer concentrate is highly flammable. It could ignite if it comes into contact with hot engine component parts or the exhaust system.

Make sure that no windshield washer concentrate spills out next to the filler opening.

NOTE Damage to the exterior lighting due to unsuitable windshield washer fluid

Unsuitable windshield washer fluid may damage the plastic surface of the exterior lighting.

Only use windshield washer fluid which is also suitable for use on plastic surfaces, e.g. MB SummerFit or MB Winter‐ Fit.

NOTE Blocked spray nozzles caused by mixing windshield washer fluids

Do not mix MB SummerFit and MB WinterFit with other windshield washer fluids.

Do not use distilled or de-ionized water. Otherwise, the fill level sensor may be triggered erroneously.

Recommended windshield washer fluid:

• Above freezing point: e.g. MB SummerFit
• Below freezing point: e.g. MB WinterFit

For the correct mixing ratio, refer to the information on the antifreeze container.

Mix washer fluid with windshield washer fluid all year round.
