Point garage door remote control A
towards buttons ;to? on the rear-view
mirror at a distance of 5 to 20 cm.
i The required distance between remote
control Aand the integrated garage door
opener depends on the garage door drive
system. You might require several
attempts. You should test every position for
at least 25 seconds before trying another
position.
X Press and hold button Bon remot econtrol
A until indicator lamp :lights up green.
If indicator lamp :lights up green or
flashes, then programming has been suc-
cessful.
X Release button ;,=or? on the inte-
grated garage door opener and button B
on garage door remote control A.
If indicator lamp :lights up red:
X Repeat the programming procedure for the
corresponding button on the rear-view mir-
ror. When doing so, vary the distance
between remote control Aand the rear-
view mirror.
i If the indicator lamp flashes green after
successful programming, the garage door
system is using a rolling code. After pro-
gramming, you must synchronise the
garage door opener integrated in the rear-
view mirror with the receiver of the garage
door system.
Synchronising the rolling code
Your vehicle must be within reach of the
garage door or exterior gate drive. Make sure
that neither your vehicle nor any persons/
objects are present within the sweep of the
door or gate.
Observe the safety notes when performing
the rolling code synchronisation
(Y page 243). X
Turn the key to position 2in the ignition
lock.
X Press the programming button of the door
or gate drive (see the door or gate drive
operating instructions, e.g. under "Pro-
gramming of additional remote controls").
i Usually, you now have 30seconds to ini-
tiate the next step.
X Press previously programmed button ;,
= or? of the integrated garage door
opener until the door starts to move.
The rolling code synchronisation is then
complete.
Problems when programming
If you have problems when programming the
integrated garage door opener, please note
the following:
R Check the transmitter frequency of garage
door drive remote control A.This can usu-
ally be found on the back of the remote
control.
R Change the batteries in garage door remote
control A.This increases the likelihood
that remote control Awill send a strong
and precise signal to the integrated garage
door opener.
R When programming, hold remote control
A at varying distances and angles from the
button that you are programming. Try vari-
ous angles at a distance of between
5 and 30 cm or at the same angle but at
varying distances.
R If there is another remote control for the
same garage door drive, perform the pro-
gramming 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 the remote control goes out). Press but- 244

Maintaining the time-dependent service
schedule:
X
Note down the service due date displayed
in the multifunction display before discon-
necting the battery.
or
X Subtract the battery disconnection periods
from the service date shown on the display
after reconnecting the battery.
Hiding aservice message X
Press the %ora button on the steer-
ing wheel.
Displaying service messages X
Switch on the ignition.
X Press =or; on the steering wheel
to selec tthe Serv. menu.
X Press 9or: to select the ASSYST PLUS submenu and press
ato confirm.
The service due date appears in the multi-
function display.
Points to remember Resetting the ASSYST PLUS service inter-
val display
Aq ualified specialist workshop, e.g. a
Mercedes-Ben zService Centre, will reset the
ASSYST PLUS service interval display after
the necessary service work has been carried
out.
You can obtain further information, e.g.
regarding service work, from a Mercedes-
Benz Service Centre or directly from
Mercedes-Benz.
! If the ASSYST PLUS service interval dis-
play has been inadvertently reset, this set-
ting can be corrected at a Mercedes-Benz
Service Centre.
Have service work carried out as described
in the Service Booklet. This may otherwise lead to increased wear and damage to the
major assemblies or the vehicle.
Driving abroad
An extensive Mercedes-Benz Service network
is also available in other countries. The
Service Hotline's curren ttelephone numbers
for use when you are abroad are to be found
in the "Mercedes-BenzS ervice24h" section
of the Service Booklet. Care
Notes on care
Regular care of your vehicle is a condition for
retaining the quality in the long term.
Use care products and cleaning agents rec-
ommended and approved by Mercedes-Benz.
! For cleaning your vehicle, do not use any
of the following:
R dry, rough or hard cloths
R abrasive cleaning agents
R solvents
R cleaning agents containing solvents
Do not scrub.
Do not touch the surfaces or protective
films with hard objects, e.g. a ring or ice
scraper. You could otherwise scratch or
damage the surfaces and protective film. H
Environmental note
Dispose of empty packaging and cleaning
cloths in an environmentally responsible man-
ner.
! Do not park up the vehicle for an extended
period straight after cleaning it, particularly
after having cleaned the wheels with wheel
cleaner. Wheel cleaners could cause
increased corrosion of the brake discs and
brake pads/linings. For this reason, you
should drive for a few minutes after clean-
ing. Braking heats the brake discs and the
brake pads/linings, thus drying them. The
vehicle can then be parked up. Care
253Maintenance and care Z
cloths could scratch or damage the plastic
lenses of the mirror turn signals.
X Clea nthe plastic lenses of the mirror turn
signals using a wet sponge and a mild
cleaning agent, e.g. Mercedes-Ben zcar
shampoo. Cleaning cloths may be used as
well.
Cleaning the sensors X
Clean sensors :of the driving systems
with water, car shampoo and a sof tcloth.
! If you clean the sensors with a high-pres-
sure cleaner, make sure that you keep a
distance of at least 30 cm between the
vehicle and the high-pressure cleaner noz-
zle. Information about the correct distance
is available fro mthe equipment manufac-
turer.
Cleaning the exhaust tail pipes Impurities combined with the effects of road
grit and corrosive environmental factors may
cause flash rust to form on the surface. You
can restore the original shine of the exhaust
tail pipe by cleaning it regularly, especially in
winter and after washing.
! Do not clean the exhaust tail pipes with
alkaline-based cleaning agents, such as
wheel cleaner. X
Cleant he exhaust tail pipes with a chrome
care product tested and approved by
Mercedes-Benz. Interior care
Cleaning the display X
Before cleaning the display, make sure that
it is switched off and has cooled down.
X Cleant he display surface using a commer-
cially-available microfibre cloth and TFT/
LCD display cleaner.
X Dry the display surface using a dry micro-
fibre cloth.
! For cleaning, do not use any of the fol-
lowing:
R alcohol-based thinner or petrol
R abrasive cleaning agents
R commercially-available household clean-
ing agents
These may damage the display surface. Do
not put pressure on the display surface
when cleaning. This could lead to irrepara-
ble damage to the display.
Cleaning the plastic trim G
WARNING
When cleaning the steering wheel boss and
dashboard, do not use cockpit sprays or
cleaning agents containing solvents. Cleaning
agents containing solvents cause the surface
to become porous, and as aresult plastic
parts may break away and be thrown around
the interior when an airbag is deployed, which
may result in severe injuries.
! Do not affix the following to plastic surfa-
ces:
R stickers
R films
R scented oil bottles or similar items
You could otherwise damage the plastic. Care
