0OffI Intermittent wiping 
Vehicles with optional rain sensor:
One initial wipe, pauses between wipes are 
automatically controlled by a rain sensor 
monitoring the wetness of the windshield. This 
will not occur with a door open.
Notes:
With switch in this position, one wipe occurs 
when turning the electronic key in starter switch 
from position 0. However, this might cause 
scratches in a dry windshield. Turn combination 
switch to Off position before turning the 
electronic key in starter switch from position 0.
Do not leave in intermittent setting when vehicle 
is taken to an automatic car wash or during 
windshield cleaning. Wipers will operate in 
presence of water spray at windshield, and 
wipers may be damaged as a result.
II Normal wiper speed
III Fast wiper speed
Vehicles without optional rain sensor:
If the vehicle is standing still, the wiper will 
switch back one setting.

Blocked windshield wipers
If the windshield wipers become blocked (for example, 
due to snow), switch off the wipers.
For safety reasons before removing ice or snow, remove 
electronic key from starter switch. Remove blockage.
Activate combination switch again (electronic key in 
starter switch position 1).
Emergency operation of windshield wipers
In case of windshield wiper malfunction in switch 
positions I or III, turn combination switch to wiper 
setting II. Have the system checked at your authorized 
Mercedes-Benz Center as soon as possible.Windshield wipers smear
If the windshield wipers smear the windshield, even 
during rain, activate the washer system as often as 
necessary. The fluid in the washer reservoir should be 
mixed in the correct ratio.
See page 320 for instructions on filling up the 
windshield washer reservoir.
See page 356 for instructions on replacing wiper blade 
inserts.
Windshield and headlamp washer fluid mixing ratio
For temperatures above freezing:
MB Windshield Washer Concentrate “S” and water.
1 part “S” to 100 parts water
(40 ml “S” to 1 gallon water).
For temperature below freezing:
MB Windshield Washer Concentrate “S” and 
commercially available premixed windshield washer

1 part “S” to 100 parts solvent
(40 ml “S” to 1 gallon solvent).

data Instruments

cluster displayPractical hints Car care Index Climate control
The system is always at operational readiness, except 
when manually switched off.
The climate control only operates with the engine 
running.
The temperature selector should be left at the desired 
temperature setting. The temperature selected is 
reached as quickly as possible.
The system will not heat or cool any quicker by setting a 
higher or lower temperature.
The desired interior temperature can be selected 
separately for the left and right side of the passenger 
compartment. Adjust the temperature settings in small 
increments.
The climate control removes considerable moisture from 
the air during operation in the cooling mode. It is 
normal for water to drip on the ground through ducts in 
the underbody.
The air conditioning will not engage (no cooling) if the 
economy mode S is selected, see page 159. Notes:
Do not obstruct the air flow by placing objects on the air 
flow-through exhaust slots below the rear window.
Also keep the air intake grill in front of the windshield 
free of snow and debris.
The storage compartment between the front seats can be 
ventilated. See page 171 for notes on ventilating the 
storage space under the armrest in the center console.
The air conditioner switches itself off for its own 
protection if refrigerant is lost. No cooling will then take 
place. Economy mode S cannot be switched off. Have 
the air conditioner checked by a Mercedes-Benz Center 
should this happen.
If the vehicle interior has been heated by direct sunlight 
and is very hot, ventilate the interior (open door or 
windows for a short period) before driving off.
Dust filter
Nearly all dust particles and pollen are filtered out 
before outside air enters the passenger compartment 
through the air distribution system.
