2015 MERCEDES-BENZ E-CLASS CABRIOLET ignition

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.
Opening or closing the garage door Once programmed, the integrated garage door
opener will assume the function of the garage
door system's remote control. Please also read
the operating instructions for the garage door
system.
X Turn the key to position 2in the ignition lock
(Y page 139).
X Press button ;,=or? which you have
programmed to operate the garage door.
Garage door system with a fixed code: indi-
cator lamp :lights up green.

The transmitter will transmit a signal for as
long as the button is pressed. The transmis-
sion is halted after a maximum of ten seconds
and indicator lamp :lights up yellow.
X Press button ;,=or? again if necessary.

Special service requirements The prescribed service interval is based on nor-
mal operation of the vehicle. Service work will
need to be performed more often if the vehicle is operated under arduous conditions or increased
loads, for example:
R regular city driving with frequent intermediate
stops
R if the vehicle is primarily used to travel short
distances
R for frequent operation in mountainous terrain
or on poor road surfaces
R if the engine is often left idling for long periods
In these or similar operating conditions, have,
for example, the air filter, engine oil and oil filter changed more frequently. The tyres must be
checked more frequently if the vehicle is oper- 294
ServiceMaintenance and care

!
When DISTRONIC PLUS or the HOLD func-
tion is activated, the vehicle brakes automat- ically in certain situations.
To avoid damage to the vehicle, deactivate
DISTRONIC PLUS and the HOLD function in
the following or similar situations:
R when towing away
R in a car wash
! Preferably use car washes with adjustable
high-pressure jets for pre-washing. This cor-
responds with the specifications for cabriolet
programmes. In car washes that use high
water pressures, there is a risk that a small
amount of water may leak into the vehicle.
! Make sure that the vehicle is not subse-
quently treated with hot wax.
! Make sure that:
R the side windows and sliding sunroof or
soft top are closed completely.
R the blower for the ventilation/heating is
switched off (OFF button is depressed).
R the windscreen wiper switch is at position
0.
The vehicle could otherwise be damaged.
! In car washes with a towing mechanism,
make sure that the automatic transmission is
in transmission position N; otherwise, the
vehicle could be damaged.
R Vehicles with DIRECT SELECT lever and
key:
do not remove the key from the ignition
lock. Do not open the driver's door or front- passenger door when the engine is
switched off. Otherwise, the automatic
transmission selects park position Pauto-
matically and locks the wheels. You can
prevent this by shifting the automatic trans-
mission to Nbeforehand.
R Vehicles with DIRECT SELECT lever and
KEYLESS-GO:
do not open the driver's door or front-
passenger door when the engine is
switched off. Otherwise, the automatic
transmission selects park position Pauto-
matically and locks the wheels.
Observe the following to make sure that the
automatic transmission on vehicles with DIRECT
SELECT stays in position N:X
Make sure the vehicle is stationary and the
ignition is switched off.
X Turn the key to position 2in the ignition lock
(Y page 139).
Use the key instead of the Start/Stop button on vehicles with KEYLESS-GO.
X Depress the brake pedal and keep it
depressed.
X Shift the automatic transmission to position
N.
X Release the brake pedal.
X Release the parking brake.
X Switch off the ignition and leave the key in the
ignition lock.
You can wash the vehicle in an automatic car
wash from the very start.
Wash off excess dirt before cleaning the vehicle
in an automatic car wash.
After using an automatic car wash, wipe off wax
from the windscreen and the wiper blades. This
will prevent smears and reduce wiping noises
caused by residue on the windscreen.
Washing by hand In some countries, washing by hand is only
allowed at specially equipped washing bays.
Observe the legal requirements for each indi-
vidual country.
X Do not use hot water and do not wash the
vehicle in direct sunlight.
X Use a soft sponge to clean.
X Use a mild cleaning agent, such as a car
shampoo approved by Mercedes-Benz.
X Thoroughly hose down the vehicle with a gen-
tle jet of water.
X Do not point the water jet directly towards the
air inlet.
X Use plenty of water and rinse out the sponge
frequently.
X Rinse the vehicle with clean water and dry
thoroughly with a chamois.
X Do not let the cleaning agent dry on the paint-
work.
When using the vehicle in winter, remove all
traces of road salt deposits carefully and as
soon as possible. 296
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).
