6Heated air supply
7Non-heated/cooled air supply
Basic mode:
None of the push-buttons (6 or 7) is pressed.
8Display and controls, see page 92The 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 h eat or cool a ny quicker by setting a
higher or lower temperature.
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.
Important!
This vehicle is equipped with an air conditioner 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.

Air recirculation
This mode can be selected to temporarily reduce the
entry of annoying odors or dust into the vehicle’s
interior.
Outside air is not supplied to the car’s interior.
To select, press O button.
To cancel, press O button again.
The system will automatically switch from recirculated
air to fresh air
• after approx. 5 minutes at outside temperatures
below approx. 40°F (5°C),
• after approx. 30 minutes, at outside temperatures
above approx. 40°F (5°C),
• after approx. 5 minutes, if button S is pressed.
Notes:
If the windows should fog up from the inside, switch
from recirculated air back to fresh air.
At high outside temperatures, the system automatically
engages the recirculated air mode thereby increasing
the cooling capacity performance, switching to partially
fresh air within 20 minutes.Residual engine heat utilization
With the engine switched off, it is possible to continue
heating the interior for a short while.
Air volume and distribution are controlled
automatically.
To select:
Turn electronic key in steering lock to position 1 or 0 or
remove electronic key.
Press T button.
This function selection will not activate if the battery
charge level is insufficient.
To c a n c e l :
Press T button.
The system will automatically shut off
• If you turn electronic key in steering lock to
position 2,
• after approx. 30 minutes,
• if the battery voltage drops.

Ashtray in center console
By touching the bottom of the cover lightly, the ashtray
opens automatically.
Prior to removing the ashtray insert, move the gear
selector lever to position “N”.To remove ashtray:
Push sliding knob (1) toward the right to eject the
insert.
To install ashtray:
Install insert into ashtray frame and push down to
engage.
Wa r n i n g !
Remove front ashtray only with vehicle standing
still. With the gear selector lever in position “N”,
turn off the engine and set the parking brake.
Otherwise the vehicle might move as a result of
unintended contact with the gear selector lever.

Telephone, general
See separate instruction manual for instructions on how
to operate the telephone.
1 Observe the legal requirements in all countries concerned.
Wa r n i n g !
Your concentration on the road and traffic
conditions must take priority. Only use the
telephone
1 when road and traffic conditions
permit.
Park if you wish to use the handset rather than the
hands-free device to make a call.Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is covering
a distance of approximately 50 feet (approximately
14 m ) e v e r y s e c o n d .
Never operate radio transmitters equipped with a
built-in or attached antenna (i.e. without being
connected to an external antenna) from inside the
vehicle while the engine is running. Doing so could
lead to a malfunction of the vehicle’s electronic
system, possibly resulting in an accident and
personal injury.

4. Within 10 seconds of turning key in steering lock to
position 2 (engine not running), slide soft top
switch (2) back and hold.
Please note, if soft top switch is activated after
10 seconds have expired, turn the key back to
position 0 first before the hardtop removing
procedure can be started again at step 4.The unlocking procedure begins after approx.
2seconds:
•The roll bar lowers.
• The indicator lamp in the soft top switch lights
up.
• The hardtop unlocks.

cluster displayPractical hints Car care Index
Notes:
For safety reasons, the hardtop can only be unlocked
while the vehicle is standing still, and within
10 seconds after turning the key to steering lock
position 2 or beyond.
If the indicator lamp in the soft top switch blinks while
activating the switch, the battery voltage may be
insufficient - start engine to charge battery before
shutting engine off and attempting to unlock the roof
again.
If the indicator lamp continues to blink, remove the
hardtop (see page 137), and have the system checked at
your authorized Mercedes-Benz Center as soon as
possible.
Wa r n i n g !
The raising or lowering procedure of the soft top is
not completed if the indicator lamp in the soft top
switch:
• does not go out (with key in steering lock
position 2),
• blinks when starting to drive and an alarm
sounds.When safe to do so, immediately stop the vehicle
and lock the soft top:
• Turn key in steering lock to position 2,
• Slide soft/hardtop switch forward.Do not drive the car with the hardtop not locked, as
that could cause personal injury to you or your
passenger, or personal injury or property damage
to others.

147 Soft top
Technical
data Instruments
and controlsOperationDrivingInstrument
cluster displayPractical hints Car care Index For safety reasons, the soft top cannot be unlocked
while driving.
However, if the soft top is not completely locked, it can
be locked while driving by pushing the soft/hardtop
switch forward.
If the indicator lamp in the soft top switch blinks while
activating the switch,
• the battery voltage may be insufficient - start engine
and let run while activating switch,
• the system may be overloaded (for example after
lowering or raising the soft top approx.
5 consecutive times) - after approx. 2 minutes the
soft top switch may be activated again,
• and the power supply was interrupted (battery
disconnected or empty), the soft top cannot be fully
raised or lowered.
To raise the soft top, for safety reasons, first remove key
from steering lock. Lower soft top by hand into
compartment, and resynchronize the power windows.
See page 116.
To lower the soft top, first resynchronize the power
windows. See page 116.If t he indicator la mp continues to bl ink, l ock th e sof t top
manually. See page 253.
Have the system checked at your authorized Mercedes-
Benz Center as soon as possible.
Note:
If the roll bar was raised automatically, the process of
raising or lowering the soft top will take somewhat
longer, as the roll bar must first be lowered.
Whenever possible, park vehicle in the shade as
continuous exposure to sun rays can prematurely
deteriorate the soft top material.
Permanent creases in the plastic window, caused by
storage of the soft top in the storage compartment,
cannot be avoided.
The soft top may become moldy if it is kept in the
storage compartment for an extended period.
Therefore, we recommend raising and airing it
thoroughly with the side windows open (do not expose
it to the sun) at regular intervals during the wet and
cold seasons.

Radio, telephone and two-way radio
1 Observe all legal requirements.
Telephones and two-way radio
Radio transmitters, such as a portable telephone or a
citizens band unit should only be used inside the
vehicle if they are connected to an antenna that is
installed on the outside of the vehicle.
Refer to the radio transmitter operation instructions
regarding use of an external antenna.
Wa r n i n g !
Please do not forget that your primary
responsibility is to drive the vehicle. Only operate
the radio, telephone
1 or two-way radio

traffic conditions permit.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is covering
a distance of approximately 50 feet (approximately
