Important!
Prior to operating the vehicle, the driver should check
and adjust if necessary the seat height, seat position
fore and aft, and backrest angle to insure adequate
control, reach and comfort. The head restraint should
also be adjusted for proper height. See also airbag
section for proper seat positioning.
In addition, also adjust the steering wheel to ensure
adequate control, reach, operation and comfort. Both the
inside and outside rear view mirrors should be adjusted
for adequate rearward vision.
Fasten seat belts. Infants and small children should be
seated in a properly secured restraint system that
complies with U.S. Federal Motor Vehicle Safety
Standard 213 and Canadian Motor Vehicle Safety
Standard 213.
All seat, head restraint, steering wheel, and rear view
mirror adjustments as well as fastening of seat belts
should be done before the vehicle is put into motion.
Wa r n i n g !
Children 12 years old and under must never ride in
the front seat, except in a Mercedes-Benz
authorized BabySmart
TM compatible child seat,
which operates with the BabySmart
TM system
installed in the vehicle to deactivate the passenger-
side front airbag when it is properly installed.
Otherwise they will be struck by the airbag when it
inflates in a crash. If this happens, serious or fatal
injury can result.
According to accident statistics, children are safer
when properly restrained in the rear seating
positions than in the front seating positions.
Infants and small children must ride in back seats
and be seated in an appropriate infant or child
restraint system, which is properly secured with
the vehicle’s seat belt, fully in accordance with the
child seat manufacturer’s instructions.A child’s risk of serious or fatal injuries is
significantly increased if the child restraints are
not properly secured in the vehicle and the child is
not properly secured in the child restraint.

169 Automatic climate control
Te ch n i c a l

and controlsOperationDrivingInstrument
cluster displayPractical hints Car care Index Automatic climate control
The system is always at operational readiness, except
when manually switched off.
The automatic 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 and air distribution
can be selected separately for the left and right side of
the passenger compartment. Adjust the temperature
settings in small increments.
The automatic 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 AC
OFF
is selected, see page 176. Notes:
The current settings (Temperature, Air volume, AC
OFF,
Activated charcoal filter, ON / OFF) are stored for each
electronic key before the electronic key is removed from
the starter switch or when the vehicle is locked using
the KEYLESS-GO-card (vehicles with keyless-go), see
key dependent memory settings on page 111.
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 178 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 AC
OFF
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.

To help avoid personal injury during a collision or
sudden maneuver, exercise care when stowing
things. Put luggage or cargo in the trunk if
possible. Do not pile luggage or cargo higher than
the seat backs. Do not place anything on the shelf
below the rear window.Luggage nets cannot secure hard or heavy objects. Wa r n i n g !
