Problems with the steering wheel heating
Problem
Possible causes/consequences and
M
MSolutions The steering wheel
heating has switched
itself off prematurely or
cannot be switched on. The on-board voltage is too low because too many electrical con-
sumers are switched on.
X Switch off electrical consumers that you do not need, such as
the rear window heating or interior lighting. EASY-ENTRY/EXIT feature
Important safety notes G
WARNING
When the EASY-ENTRY/EXIT feature adjusts
the steering wheel and the driver's seat, you
and other vehicle occupants – particularly
children – could become trapped. There is a
risk of injury.
While the EASY-ENTRY/EXIT feature is mak-
ing adjustments, make sure that no one has
any body parts in the sweep of the seat and
the steering wheel.
If there is a risk of becoming trapped by
R the steering wheel: move the steering
wheel adjustment lever.
R the seat: press the switch for seat adjust-
ment.
The adjustment process is stopped.
Press one of the memory function position
switches. The adjustment process is stopped. G
WARNING
If children activate the EASY-ENTRY/EXIT fea- ture, they can become trapped, particularly
when unattended. There is a risk of injury.
When leaving the vehicle, always take the key with you and lock the vehicle. Never leave
children unattended in the vehicle. G
WARNING
If you drive off while the EASY-ENTRY/EXIT
feature is making adjustments, you could lose
control of the vehicle. There is a risk of an
accident. Always wait until the adjustment process is
complete before driving off.
The EASY-ENTRY/EXIT feature makes getting in and out of your vehicle easier.
You can activate and deactivate the EASY-
ENTRY/EXIT feature using COMAND Online
(see the separate operating instructions).
Position of the steering wheel and the
driver's seat when the EASY-ENTRY/
EXIT feature is active The steering wheel tilts upwards and the driv-
er's seat moves backwards if you:
R remove the key from the ignition lock
R with KEYLESS-GO: open the driver's door;
KEYLESS-GO must be in position 1
R with the key: open the driver's door; the
key must be in position 0or 1in the ignition
lock (Y page 161)
R open the driver's door when the ignition is
switched off
i The steering wheel only tilts upwards and
the driver's seat only moves backwards if
the driving position is stored after seat or
steering wheel adjustment.
The last position of the steering wheel or seat is stored if:
R the ignition is switched off
R the setting is stored using the memory
function (Y page 123)
i The steering wheel only moves upwards if
it has not already reached the upper stop. 118
Steering wheelSeats, steering wheel and mirrors

The driver's seat moves backwards unless
it is already in the rearmost position.
Position of the steering wheel and the
driver's seat for driving The steering wheel and the driver's seat are
moved to the previously set position if:
R the driver's door is closed and you insert
the key into the ignition lock
R you close the driver's door when the igni-
tion is switched on
R you press the Start/Stop button once on
vehicles with KEYLESS-GO
i The steering wheel and the driver's seat
only return to the last set position when the
driving position is stored after seat or steer-
ing wheel adjustment.
The last position of the steering wheel or seat is stored if:
R the ignition is switched off
R the setting is stored using the memory
function (Y page 123)
Crash-responsive EASY-EXIT feature If the crash-responsive EASY-EXIT feature is
triggered in an accident, the steering column
will move upwards when the driver's door is
opened or the key is removed from the igni-
tion lock. This makes it easier to exit the vehi-
cle and rescue the occupants.
The crash-responsive EASY-EXIT feature is
only operational if the EASY-EXIT/ENTRY fea-
ture is activated in COMAND Online (see the
separate operating instructions). Mirrors

Important safety notes G
WARNING
You could lose control of the vehicle while
driving if you:
R adjust the driver's seat, steering wheel or
mirrors
R fasten the seat belt
There is a risk of an accident.
Adjust the driver's seat, head restraint, steer-
ing wheel and mirrors and fasten your seat
belt before starting the engine. G
WARNING
The exterior mirrors reduce the size of the
image. Objects visible in the mirrors are
closer than they appear. You could misjudge
the distance from road users driving behind
you when changing lanes, for instance. There is a risk of an accident.
You should therefore always look over your
shoulder to determine the actual distance
from road users driving behind you. Mirrors

the case if you are not depressing the brake
pedal.
If you depress the brake pedal and press the
Start/Stop button, the engine starts immedi-
ately.
A check which periodically establishes a radio
connection between the vehicle and the key
determines whether a valid key is in the vehi- cle. This occurs, for example, when starting
the engine.
To start the vehicle without actively using the
key:
R the Start/Stop button must be inserted in
the ignition lock
R the key must be in the vehicle
R the vehicle must not be locked with the key
or KEYLESS-GO (Y page 85)
Do not keep the key:
R with electronic devices, e.g. a mobile
phone or another key
R with metallic objects, e.g. coins or metal
film
R inside metallic objects, e.g. a metal case
This can affect the key's functionality.
If you lock the vehicle with the key's remote
control or with KEYLESS-GO, after a short
time:
R you will not be able to switch on the ignition
with the Start/Stop button
R you will not be able to start the engine with
the Start/Stop button until the vehicle is
unlocked again
If you lock the vehicle centrally using the but- ton on the front door (Y page 91), you can
continue to start the engine with the Start/
Stop button.
The engine can be switched off while the vehi-
cle is in motion by pressing and holding the

CareMaintenance and care

Wash off excess dirt before cleaning the vehi-
cle 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 wind- screen.
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
gentle 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
paintwork.
When using the vehicle in winter, remove all
traces of road salt deposits carefully and as
soon as possible.
High-pressure cleaning equipment G
WARNING
The water jet of circular-jet nozzles (dirt grind- ers) can cause damage not visible from the
outside to tyres or chassis components. Com-
ponents damaged in this way can unexpect-
edly fail. There is a risk of an accident.
Do not use high-pressure cleaners with circu-
lar-jet nozzles to clean the vehicle. Have dam- aged tyres or chassis components replaced
immediately. !
Always maintain a distance of at least
30 cm between the vehicle and the high-
pressure cleaner nozzle. Information about
the correct distance is available from the
equipment manufacturer.
Move the high-pressure cleaner nozzle
around when cleaning your vehicle.
Do not aim directly at any of the following:
R tyres
R door gaps, roof gaps, joints etc.
R electrical components
R battery
R connectors
R lights
R seals
R trim elements
R ventilation slots
Damaged seals or electrical components
can lead to leaks or failures.
! If the key is within the rear detection
range of KEYLESS-GO, the following situa-
tions, for example, could lead to the boot lid opening unintentionally:
R using a car wash
R using a high-pressure cleaner
Make sure that the key is at least 3 m away
from the vehicle.
Cleaning the paintwork !
Do not affix:
R stickers
R films
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 inade-
quate care cannot always be completely
repaired. In such cases, visit a qualified spe-
cialist workshop. Care
