Important safety notes G
WARNING
When you operate or program the garage door with the integrated garage door opener, per-
sons in the range of movement of the garage
door can become trapped or struck by the
garage door. There is a risk of injury.
When using the integrated garage door
opener, always make sure that nobody is
within the range of movement of the garage
door. G
WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces with-
out sufficient ventilation.

283Stowing and features Z

Several attempts may be required. You
should test every position for at least
25 seconds before trying another position.
Synchronising the rolling code
Observe the "Important safety notes"
(Y page 283).
If the garage door system uses a rolling code,
you will also have to synchronise the garage
door system with the integrated garage door
opener in the rear-view mirror. To do this, you
will need to use the programming button on the
door drive control panel. The programming but-
ton may be placed at different locations depend- ing on the manufacturer. It is usually located on
the door drive unit on the garage ceiling.
Familiarise yourself with the garage door drive
operating instructions, e.g. under "Program-
ming of additional remote controls", before car-
rying out the following steps.
Your vehicle must be within range of the garage
door or gate opener drive. Make sure that nei-
ther your vehicle nor any persons/objects are
present within the sweep of the door or gate.
X Turn the key to position 2in the ignition lock
(Y page 139).
X Get out of the vehicle.
X Press the programming button on the door
drive unit.
Usually, you now have 30 seconds to initiate
the next step.
X Get into the vehicle.
X Press previously programmed button ;,=
or ? of the integrated garage door opener
until the door closes.
The rolling code synchronisation is then com- plete.
Problems when programming
If you have problems when programming the
integrated garage door opener, please note the following:
R Check the transmitter frequency used by
garage door drive remote control Aand
whether it is supported. The transmitter fre-
quency can usually be found on the back of
the garage door drive remote control.
R Replace the batteries in garage door remote
control A. This increases the likelihood that
garage door remote control Awill transmit a
strong and precise signal to the integrated
garage door opener in the rear-view mirror. R
When programming, hold remote control A
at varying distances and angles from the but-
ton which you are programming. Try various
angles at a distance between 5and 20cm or
at the same angle but at varying distances.
R If there is another remote control for the same
garage door drive, perform the programming
steps again using this remote control. Before
performing these steps, make sure that new
batteries have been fitted in garage door drive remote control A.
R Note that some remote controls transmit only
for a limited period (the indicator lamp on theremote control goes out). Press button Bon
remote control Aagain before transmission
ends.
R Align the aerial cable of the garage door
opener unit. This can improve signal recep-
tion/transmission.

CareMaintenance and care

Cleaning vehicle parts
Cleaning the soft top !
Never use any of the following to clean the
soft top:
R petrol
R thinner
R tar or stain remover
R other organic solvents
! Remove bird droppings immediately as they
are corrosive and, therefore, can make the
soft-top fabric leak. Do not use high-pressure cleaning equipment to clean the vehicle. Do
not use sharp-edged equipment to remove ice
and snow.
X Light soiling: you can clean the soft top while
it is dry or rinse it with clear water.
X Normal to heavy soiling: clean the roof with
a brush and clear water. Clean stains and
other dirt with a brush and a Mercedes-Benz
recommended and approved cleaning agent.
Always brush from front to back in the direc-
tion of the fabric.
Frequent cleaning reduces the soft top's resist- ance to dirt.
To restore this resistance to dirt, clean the soft
top using soft-top cleaning agents that have
been recommended and approved by
Mercedes-Benz.
Incorrect cleaning and care, as well as ageing,
can cause the soft-top seams to leak. Have the
soft-top seams sealed at a qualified specialist
workshop, e.g. at a Mercedes-Benz Service
Centre.
i Cover the soft top appropriately if you plan
to leave the vehicle outside for a long period
of time.
Cleaning AIRCAP Cleaning the wind deflector
! Do not use high-pressure cleaning equip-
ment to clean the net.
Clean the wind deflector on the windscreen with
the soft top closed.
X Apply the parking brake firmly.
X Vehicles with key: turn the key to position
2 (Y page 139) in the ignition lock. X
Vehicles with KEYLESS-GO: press the
Start/Stop button twice (Y page 139).
X Open the cover on the lower centre console.
The AIRCAP button is under the cover. X
Press AIRCAP button :.
The wind deflector between the windscreen
and the soft top is extended. X
Clean net ;of the wind deflector with a soft
brush or a moist cloth. For heavier soiling,
clean it with the care and cleaning agents
recommended and approved by Mercedes-
Benz and rinse it with clean water.
Cleaning the AIRCAP draught stop
Clean the AIRCAP draught stop with the soft top
open.
