0Off I 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.

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.

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.

Important!
This vehicle is equipped with an air conditioning
system that uses R-134a (HFC: hydrofluorocarbon) as a
refrigerant. Repairs should always be performed by a
qualified technician, and refrigerant should be collected
in a recovery system for recycling.

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.
