line mentioned above. Problems when programming
If you experience problems when program-
ming the garage door opener integrated in the
rear-view mirror, note the following:
R
check the transmitter frequency of garage
door remote control A(this can usually be
found on the rear of the remote control).
R change the batteries in garage door remote
control A.This increases the likelihood
that garage door remote control Awill
send a strong and precise signal to the
integrated remote control in the rear-view
mirror.
R when programming, hold garage door
remote control Aat different distances
and angles from the transmitter button that
you are programming. Try various angles at
distances from 5 to 30 cm or the same
angle but varying distances.
R If there is another remote control for the
same garage door drive, perform the pro-
gramming steps again using the other
remote control. Before performing these
steps, make sure that new batteries have
been fitted in the garage door remote con-
trol.
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 remote
control will assume the function of the garage
door system's remote control. Please also
read the operating instructions for the garage
door system.

Risk of injury
The radiator fan between the radiator and the
engine can start automatically, even if the key
has been removed from the ignition lock. For
this reason, you must not reach into the fan
rotation area. You could otherwise be injured. Vehicles with
apetrol engine: The elec-
tronic ignitio nsystem uses high voltage. For
this reason, you mus tnever touch ignition
system components (ignition coil, ignition
cables, spark plug connectors or test socket)
while:
R the engine is running
R the engine is being started
R the ignition is switched on and the engine
is being cranked by hand
You could otherwise suffer an electric shock
and be seriously or even fatally injured.
Vehicles with adiesel engine: The elec-
tronic injection control uses high voltage. For
this reason, you must never touch injection
system components while:
R the engine is running

Engine compartmentMaintenance and care

X
Slowly insert oil dipstick :into the oil dip-
stick tube to the stop ,and take it ou tagain.
The oil level is correc tifthe level is between
MIN mark =and MAX mark ;.
X Top up the oil if necessary.
Adding engine oil H
Environmental note
When topping up the oil, take care not to spill
any. If oil enters the soil or waterways, it is
harmful to the environment. Example: engine oil cap
X
Turn cap :anti-clockwise and remove it.
X Top up with the amount of oil required.
Fill carefully to the maximum mark on the oil
dipstick.
i Depending on the engine, the difference
between the minimum mark and the maxi-
mum mark is approximately 1.5 – 2 litres.
! Do not add too much oil. If the oil level is
above the "max" mark on the dipstick, too
much oil has been added. This can lead to
damage to the engine or the catalytic con-
verter. Have excess oil siphoned off.
Further information on engine oil
(Y page 320).
X Replace cap :on the filler neck and
tighten clockwise.
Ensure that the cap locks into place
securely. Checking and adding other service
products
Checking the coolant level Only check the coolant level when the vehicle
is on a level surface and the engine has cooled
down.
X
Turn the key to position 2(Y page 129) in
the ignition lock.
On vehicles with KEYLESS-GO, press the
Start/Stop button twice (Y page 129).
X Check the coolant temperature display in
the instrument cluster. G
Risk of injury
The cooling system is pressurised. Therefore,
only unscrew the cap once the engine has
cooled down. The coolant temperature gauge
must display less than 70 †.Otherwise, you
could be scalded if hot coolant escapes. X
Slowly tur ncap : half a turn anti-clock-
wise and allow excess pressure to escape.
X Turn cap :further anti-clockwise and
remove it.
If the coolant is at the level of marker bar
= in the fille rneck when cold, there is
enough coolant in coolant expansion
tank ;.
If the coolant level is approximately 1.5 cm
above marker bar =in the filler neckw hen
warm, there is enough coolant in coolant
expansion tank ;.268

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
brake pads, thus drying them. The vehicle
can then be parked up. Care of the exterior
Automatic car wash G
Risk of accident
Braking efficiency is reduced after washing
the vehicle. This could cause an accident. For
this reason, following a car wash, drive with
particular care until the brakes are dry. G
Risk of accident
The vehicle is braked when the HOLD function
or DISTRONIC PLUS is activated. Therefore,
deactivate the HOLD function and DISTRONIC
PLUS before the vehicle is washed in an auto-
matic car wash.
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.
! 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 a 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
P
automatically and locks the wheels. You
can prevent this by shifting the auto-
matic transmission to Nbeforehand.
R Vehicles with 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 P
automatically and locks the wheels.
Observe the following to make sure that the
automatic transmission stays in position N:
X Make sure the vehicle is stationary and the
ignition is switched off.
X Turn the key to position 2(Y page 129) in
the ignition lock.
Use the key instead of the Start/Stop but-
ton on vehicles with KEYLESS-GO.
X Depress and hold the brake pedal.
X Shift the automatic transmission to posi-
tion N.
X Release the brake pedal.
X Release the parking brake.
X Switch off the ignition and leave the key in
the ignition lock.
! Make sure that:
R the side windows and sliding sunroof are
closed completely.
R the blower for the ventilation/heating is
switched off (OFF button is depressed).
R the windscreen wiper switch is at posi-
tion 0.
The vehicle could otherwise be damaged.
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 wind-
screen. Care
271Maintenance and care Z

Always have paintwork repairs performed
at a qualified specialis tworkshop, e.g. a
Mercedes-Benz Service Centre.
! Do not use wash programs with a hot wax
treatment under any circumstances.

by Mercedes-Benz.
! Do not use dry cloths, abrasive products,
solvents or cleaning agents containing sol-
vents to clean the inside of the windows.
Do not use hard object sto clean the insides
of the windows, e.g. an ice scraper or ring.
There is otherwise a risk of damaging the
windows.
! Clean the water drainage channels of the
windscreen and the rear window at regular
intervals. Deposits such as leaves, petals
and pollen may under certain circumstan-
ces prevent water from draining away.T his
can lead to corrosion damage and damage
to electronic components.
