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 q uicker 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. Make 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 S is selected, see page 169.

Notes:
Do not obstruct the air f low 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 can n ot be s witched of f. 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.Basic setting – automatic mode
In the automatic mode the automatic climate control
cools or heats the interior depending on the direction
and strength of the sunlight, outside temperature and
the selected interior temperature of the vehicle. With
the automatic mode switched off, the air volume and
distribution can still be set manually.
Briefly press left or right U button. The h, j
and k symbols will no longer be visible.
The economy mode and air recirculation functions will
be switched off. The automatic blower will be activated
at the same time.
We recommend to set the temperature switches on the
left and right to 72
°F (22
°C). Please make changes from
this setting to suit your personal requirements.
Heating mode:
To lower headroom temperature, use thumbwheel
(4, page 160).
Air conditioning mode:
Open air outlets at dashboard top center (7, page 160)
for an even air distribution.

cluster displayPractical hints Car care Index Economy mode
The function of this setting corresponds to the
automatic mode. However, because the air conditioning
compressor will not engage (fuel savings), it is not
possible to air condition in this setting.
Press S button to activate. The indicator lamp in the
button illuminates.
Press S button once again to return to the previous
setting. The indicator lamp in the button goes out.
Important!
In the S mode the windows could fog up on the
inside. Switch off S mode.
Automatic climate control - OFF/ON
To switch the automatic climate control off, set the air
volume control switch to position 0.
The fresh air supply to the vehicle interior is shut off.
While driving, use this setting only temporarily,
otherwise the windshield could fog up.To switch the automatic climate control on again, press
the U or Pbutton, or set air volume control
switch to any speed.
Residual engine heat utilization
With the engine switched off, it is possible to continue
to heat or ventilate the interior for a short while,
dependent of the temperature set in the automatic
climate control. Air volume and distribution are
controlled automatically.
To s e l e c t :
Turn the electronic key in starter switch to position 1
or 0 or remove it altogether.
Press button T. The indicator lamp in the button
illuminates.
This function selection will not activate if the battery
level is insufficient.
The function switches off automatically:
•if the electronic key in starter switch is turned to
position 2,
•after approximately 30 minutes,
•if the battery voltage drops.

To keep the battery drain to a minimum, turn off the
defroster as soon as the rear window is clear.
The defroster is automatically turned off after
approximately 6–17 minutes of operation depending on
the outside temperature and vehicle speed.
If several power consumers are turned on
simultaneously, or the battery is only partially charged,
it is possible that the defroster will automatically turn
itself off. When this happens, the indicator lamp inside
the switch starts blinking.
As soon as the battery has sufficient voltage, the
defroster automatically turns itself back on.

Wa r n i n g !
In order to avoid distraction which could lead to an
accident, system settings should be entered with
the vehicle at standstill and systems should be
operated by the driver only when traffic conditions
permit. Always pay full attention to traffic
conditions first before operating system controls
while driving. Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your car is covering a
distance of 50 feet (approximately14 m) every
second.
Wa r n i n g !
Any alterations made to electronic components can
cause malfunctions.The radio, cassette deck, CD changer
1 and
telephone

one of the components is defective or has not been
removed/replaced properly this may impair the
function of other components.
These malfunctions might seriously impair the
operating safety of your vehicle.We recommend that you have any service work or
alterations to electronic components done at an
authorized Mercedes-Benz Center.

Catalytic converter
Your Mercedes-Benz is equipped with monolithic type
catalytic converters, an important element in
conjunction with the oxygen sensors to achieve
substantial control of the pollutants in the exhaust
emissions. Keep your vehicle in proper operating
condition by following our recommended maintenance
instructions as outlined in your Service Booklet.
Caution!
To prevent damage to the catalytic converters, use only
premium unleaded gasoline in this vehicle.
Any noticeable irregularities in engine operation should
be repaired promptly. Otherwise, excessive unburned
fuel may reach the catalytic converter causing it to
overheat, which could start a fire.
Wa r n i n g !
As with any vehicle, do not idle, park or operate
this vehicle in areas where combustible materials
such as grass, hay or leaves can come into contact
with the hot exhaust system, as these materials
could be ignited and cause a vehicle fire.

Drive sensibly – Save Fuel
Fuel consumption, to a great extent, depends on driving
habits and operating conditions.
To save fuel you should:
•keep tires at the recommended inflation pressures,
•remove unnecessary loads,
•remove roof rack when not in use,
•allow engine to warm up under low load use,
•avoid frequent acceleration and deceleration,
•have all maintenance work performed at regular
intervals by an authorized Mercedes-Benz Center.
Fuel consumption is also increased by driving in cold
weat her, i n stop -and -go traf f ic, on short trip s an d i n hilly
country.Drinking and driving
Ped al s
Wa r n i n g !
Drinking or taking drugs and driving can be a very
dangerous combination. Even a small amount of
alcohol or drugs can affect your reflexes,
perceptions and judgement.The possibility of a serious or even fatal accident is
sharply increased when you drink or take drugs
and drive.Please don’t drink or take drugs and drive or allow
anyone to drive after drinking or taking drugs.Wa r n i n g !
Keep driver’s foot area clear at all times. Objects
stored in this area may impair pedal movement.

Tread wear indicators (TWI) are required by law. These
indicators are located in six places on the tread
circumference and become visible at a tread depth of
approximately
1/16 in (1.5 mm), at which point the tire is
considered worn and should be replaced.
The tread wear indicator appears as a solid band across
the tread.
Wa r n i n g !
If you feel a sudden significant vibration or ride
disturbance, or you suspect that possible damage to
your vehicle has occurred, you should turn on the
hazard warning flashers, carefully slow down, and
drive with caution to an area which is a safe
distance from the roadway.Inspect the tires and under the vehicle for possible
damage. If the vehicle or tires appear unsafe, have
it towed to the nearest Mercedes-Benz Center or
tire dealer for repairs.
Wa r n i n g !
Do not allow your tires to wear down too far. As
tread depth approaches
1/16 in (1.5 mm), the
adhesion properties on a wet road are sharply
reduced.
Depending upon the weather and / or road surface
(conditions), the tire traction varies widely.
