trol 0083and the integrated garage door opener
depends on the garage door drive system.
Several attempts might be necessary. You
should test every position for at least
25 seconds before trying another position.
Synchronizing the rolling code
Pay attention to the "Important safety notes"
(Y page 226).
If the garage door system uses a rolling code,
you will also have to synchronize 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 button
may be located in different places depending on the manufacturer. It is usually located on the
door drive unit on the garage ceiling.
Familiarize yourself with the garage door drive
operating instructions, e.g. under "Program-
ming additional remote controls", before carry-
ing out the following steps.
Your vehicle must be within reach 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 SmartKey to position 2in the ignition
lock (Y page 109).
X Get out of the vehicle.

X Press previously programed button 0044,0087
or 0085 on the integrated garage door opener
repeatedly and in quick succession until the
door closes.
The rolling code synchronization is then com- plete.
Notes on programming the remote con-
trol
Canadian radio frequency laws require a "break"
(or interruption) of the transmission signals
after broadcasting for a few seconds. Therefore, these signals may not last long enough for the
integrated garage door opener. The signal is not
detected during programming. Comparable with Canadian law, some U.S. garage door openers
also feature a "break".
Proceed as follows:
R if you live in Canada
R if you have difficulties programming the
garage door opener (regardless of where you
live) as you follow the programming steps.
X Press and hold one of buttons 0044to0085 on the

Problems when programming If you are experiencing problems programming
the integrated garage door opener on the rear-
view mirror, take note of the following instruc-
tions:
R Check the transmitter frequency used by
garage door drive remote control 0083and
whether it is supported. The transmitter fre-
quency can usually be found on the back of
remote control 0083for the garage door drive.
The integrated garage door opener is com-
patible with devices that have units which
operate in the frequency range of 280 to
433 MHz.
R Replace the batteries in garage door remote
control 0083. This increases the likelihood that
garage door remote control 0083will transmit a
strong and precise signal to the integrated
garage door opener.
R When programming, hold remote control 0083
at varying distances and angles from but-
tons 0044to0085 which you are programming. Try
various angles at a distance between 2and
8 inches (5to 20 cm) or at the same angle but at varying distances.
R If another remote control 0083is available for
the same garage door drive, repeat the same
programming steps with this remote control
0083. Before performing these steps, make sure
that new batteries have been installed in
garage door drive remote control 0083.
R Note that some remote controls only transmit
for a limited amount of time (the indicator
lamp on the remote control goes out). Press
button 0084on remote control 0083again before
transmission ends.
R Align the antenna cable of the garage door
opener unit. This can improve signal recep-
tion/transmission.

control is set to position 0).
R the windshield wiper switch is at position 0.
The vehicle may otherwise be damaged.
You can wash the vehicle in an automatic car
wash from the very start.
If the vehicle is very dirty, pre-wash it before
cleaning it in an automatic car wash.
After using an automatic car wash, wipe off wax from the windshield and the wiper blades. This
will prevent smears and reduce wiping noises
caused by residue on the windshield.
Washing by hand In some countries, washing by hand is only
allowed at specially equipped washing bays.
Observe the legal requirements in each 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.
Carefully remove all deposits of road salt as
soon as possible when driving in winter.
Power washers G
WARNING
The water jet from a circular jet nozzle (dirt
blasters) can cause invisible exterior damage to the tires or chassis components. Compo- nents damaged in this way may fail unexpect-
edly. There is a risk of an accident.
Do not use power washers with circular jet
nozzles to clean the vehicle. Have damaged
tires or chassis components replaced imme-
diately.
! Always maintain a distance of at least
11.8 in (30 cm) between the vehicle and the
power washer nozzle. Information about the
correct distance is available from the equip-
ment manufacturer.
Move the power washer nozzle around when
cleaning your vehicle.
Do not aim directly at any of the following:
R Tires
R Door gaps, roof gaps, joints, etc.
R Electrical components
R Battery
R Connectors
R Lamps
R Seals
R Trim
R Ventilation slots
Damaged seals or electrical components can
lead to leaks or failures.
! Vehicles with decorative film: parts of your
vehicle are covered with a decorative film.
Maintain a distance of at least 27.5 in (70 cm)
between the parts of the vehicle covered with
the film and the nozzle of the high pressure
cleaner.
Information about the correct distance is
available from the equipment manufacturer.
Move the power washer nozzle around when
cleaning your vehicle.
Cleaning the paintwork !
Do not affix:
R stickers

R magnetic plates or similar items
to painted surfaces. You could otherwise
damage the paintwork.
Scratches, corrosive deposits, areas affected by
corrosion and damage caused by inadequate Care
235Maintenance and care Z

care cannot always be completely repaired. In
such cases, visit a qualified specialist workshop.
X Remove dirt immediately, where possible,
while avoiding rubbing too hard.
X Soak insect remains with insect remover and
rinse off the treated areas afterwards.
X Soak bird droppings with water and rinse off
the treated areas afterwards.
X Remove coolant, brake fluid, tree resin, oils,
fuels and greases by rubbing gently with a
cloth soaked in petroleum ether or lighter
fluid.
X Use tar remover to remove tar stains.
X Use silicone remover to remove wax.
If water no longer forms "beads" on the paint
surface, use the paint care products recommen-
ded and approved by Mercedes-Benz. This is the
case approximately every three to five months,
depending on the climate conditions and the
care product used.
If dirt has penetrated the paint surface or if the
paint has become dull, the paint cleaner recom- mended and approved by Mercedes-Benz
should be used.
Do not use these care products in the sun or on
the hood while the hood is hot.
X Use a suitable touch-up stick, e.g. MB Touch-
Up Stick, to repair slight damage to the paint-
work quickly and provisionally.
Matte finish care !
Never polish the vehicle or the light alloy
wheels. Polishing causes the finish to shine.
! The following may cause the paint to
become shiny and thus reduce the matte
effect:
R strong rubbing of the paintwork with
unsuitable materials
R frequent use of automatic car washes
R washing the vehicle in direct sunlight
! Never use paint cleaner, buffing or polishing
products, or gloss preserver, e.g. wax, for the purpose of paintwork care. These products
are only suitable for high-gloss surfaces. Their
use on vehicles with matte paintwork leads to considerable surface damage or, more spe-
cifically, to shiny, spotted areas.
Always have paintwork repairs carried out at a
qualified specialist workshop. !
Do not use wash programs with a hot wax
treatment under any circumstances.
Observe these notes if your vehicle has a clear
matte finish. This will help you to avoid damage to the paintwork due to incorrect treatment.
These notes also apply to light alloy wheels with
a clear matte finish.
The vehicle should ideally be washed by hand
using a soft sponge, car shampoo and plenty of water.
Use only insect remover and car shampoo from
the range of approved Mercedes-Benz care
products. Cleaning the vehicle parts
Cleaning the wheels G
WARNING
The water jet from a circular jet nozzle (dirt
blasters) can cause invisible exterior damage to the tires or chassis components. Compo-
nents damaged in this way may fail unexpect-edly. There is a risk of an accident.
Do not use power washers with circular jet
nozzles to clean the vehicle. Have damaged
tires or chassis components replaced imme-
diately.
! Do not use acidic wheel cleaning products
to remove brake dust. This could damage
wheel bolts and brake components.
! Do not park your vehicle for a long period of
time directly after cleaning, particularly after
cleaning the wheel rim with wheel cleaner.
Wheel cleaner can lead to the increased cor-
rosion of the brake discs and pads. Therefore,
drive for a few minutes after cleaning. By
heating up the brakes, the brake discs and
pads dry. The vehicle can then be parked for a long period of time.

12 V battery – important safety notes
Special tools and expert knowledge are required
when working on the batteries, e.g. removal and installation. You should therefore have all work
involving the batteries carried out at a qualified
specialist workshop. G
WARNING
The battery terminal clamps can remain under voltage even after being disconnected. If work
on the battery is carried out incorrectly, a
short-circuit may result. There is a risk of fire.
Always have work on the batteries carried out
at a qualified specialist workshop. Never dis-
connect a battery yourself. G
WARNING
Work carried out incorrectly on the battery
can lead, for example, to a short circuit and
thus damage the vehicle electronics. This can lead to function restrictions applying to
safety-relevant systems, e.g the lighting sys-
tem, the ABS (anti-lock braking system) or the
ESP ®
(Electronic Stability Program). The oper-
ating safety of your vehicle may be restricted.
You could lose control of the vehicle, for
example:
R when braking
R in the event of abrupt steering maneuvers
and/or when the vehicle's speed is not
adapted to the road conditions
There is a risk of an accident.
In the event of a short circuit or a similar inci-
dent, contact a qualified specialist workshop
immediately. Do not drive any further. You should have all work involving the battery car-
ried out at a qualified specialist workshop.
For further information about ABS and ESP ®
,
see (Y page 59) and (Y page 62). G
WARNING
Electrostatic build-up can lead to the creation of sparks, which could ignite the highly explo-
sive gases of a battery. There is a risk of an
explosion.
Before handling the battery, touch the vehicle body to remove any existing electrostatic
build-up.
The highly flammable gas mixture forms when
charging the battery as well as when jump-start- ing.
Always make sure that neither you nor the bat-
tery is electrostatically charged. A build-up of
electrostatic charge can be caused, for exam-
ple:
R by wearing clothing made from synthetic
fibers
R due to friction between clothing and seats
R if you push or pull the battery across the car-
pet or other synthetic materials
R if you rub the battery with a cloth G
WARNING
During the charging process, a battery produ- ces hydrogen gas. If a short circuit occurs or
sparks are created, the hydrogen gas can
ignite. There is a risk of an explosion.
R Make sure that the positive terminal of a
connected battery does not come into con-
tact with vehicle parts.
R Never place metal objects or tools on a bat-
tery.
R It is important that you observe the descri-
bed order of the battery terminals when
connecting and disconnecting a battery.
R When jump-starting, make sure that the
battery poles with identical polarity are
connected. 246

ing instructions. Charging the 12‑volt battery
G
WARNING
During charging and jump-starting, explosive
gases can escape from the battery. There is a risk of an explosion.
Particularly avoid fire, open flames, creating
sparks and smoking. Ensure there is sufficient
ventilation while charging and jump-starting.
Do not lean over a battery. G
WARNING
Battery acid is caustic. There is a risk of injury. Avoid contact with skin, eyes or clothing. Do
not inhale any battery gases. Do not lean over
the battery. Keep children away from batter-
ies. Wash away battery acid immediately with
plenty of clean water and seek medical atten- tion. G
WARNING
A discharged battery can freeze at tempera-
tures below freezing point. When jump-start-
ing the vehicle or charging the battery, gases can escape from the battery. There is a risk of
an explosion.
Allow the frozen battery to thaw out before
charging it or jump-starting.
! Only use battery chargers with a maximum
charging voltage of 14.8 V.
! Only
charge the battery using the jump-
starting connection point.
The jump-starting connection point is in the
engine compartment (Y page 249).
X Open the hood.
X Connect the battery charger to the positive
terminal and ground point in the same order
as when connecting the donor battery in the
jump-starting procedure (Y page 249).
If the indicator/warning lamps do not light up in
the instrument cluster at low temperatures, it is very likely that the discharged battery has fro-
zen. In this case you may neither jump-start the vehicle nor charge the battery. The service life of
a thawed-out battery may be shorter. The start-ing characteristics can be impaired, particularly at low temperatures. Have the thawed-out bat-
tery checked at a qualified specialist workshop.
Only charge the installed battery with a battery
charger which has been tested and approved byMercedes-Benz. A battery charger unit specially
adapted for Mercedes-Benz vehicles and tested
and approved by Mercedes-Benz is available as an accessory. It permits the charging of the bat-tery in its installed position. Contact an author-
ized Mercedes-Benz Center for further informa- tion and availability. Read the battery charger's
operating instructions before charging the bat-
tery. High-voltage battery – important
safety notes
G
DANGER
The vehicle's high-voltage electrical system is under high voltage. If you modify components
in the vehicle's high-voltage electrical system
or touch damaged components, you may be
electrocuted. The components in the vehi-
cle's high-voltage electrical system may be
damaged in an accident, although the damage is not visible. There is a risk of fatal injury.
Following an accident, do not touch any high- voltage components and never modify the
vehicle's high-voltage electrical system. Have
the vehicle towed away after an accident and
the vehicle's high-voltage electrical system
checked by a qualified specialist workshop. G
WARNING
In the event of a vehicle fire, the internal pres- sure of the high-voltage battery can exceed a
critical value. In this case flammable gas
escapes through a ventilation valve on the
underbody. The gas can ignite. There is a risk of injury.
Leave the danger zone immediately. Secure
the danger area at a suitable distance, whilst
observing legal requirements. 248
