General notes In order to prevent the vehicle's battery from
discharging, the interior lighting functions are
automatically deactivated after some time
except when the SmartKey is in position 2 in the

The color, brightness and display lighting for the
ambient lighting are set using the multimedia
system (see the separate operating instruc-
tions).

the multimedia system (see the separate oper-
ating instructions). Replacing bulbs
Important safety notes
G WARNING
Bulbs, lamps and connectors can get very hot
when operating. If you change a bulb, you
could burn yourself on these components.
There is a risk of injury.
Allow these components to cool down before
changing a bulb.
Do not use a bulb that has been dropped or if its
glass tube has been scratched.
The bulb may explode if: R
you touch it R
it is hot R
you drop it R
you scratch it
Only operate bulbs in enclosed lamps designed
for that purpose. Only install spare bulbs of the
same type and the specified voltage.
Marks on the glass tube reduce the service life
of the bulbs. Do not touch the glass tube with
your bare hands. If necessary, clean the glass
tube when cold with alcohol or spirit and rub it
off with a lint-free cloth.
Protect bulbs from moisture during operation.
Do not allow bulbs to come into contact with
liquids.
Only replace the bulbs listed ( Y
page 123).
Have the bulbs that you cannot replace yourself
replaced at a qualified specialist workshop.
If you require assistance replacing bulbs, con-
sult a qualified specialist workshop.
If the new bulb still does not light up, consult a
qualified specialist workshop.
Headlamps and lights are an important aspect of
vehicle safety. You must therefore make sure
that these function correctly at all times. Have
the headlamp setting checked regularly.
Veh icles with LED headlamps: t he front and
rear light clusters of your vehicle are equipped
with LED light bulbs. Do not replace the bulbs
yourself. Contact a qualified specialist work-
shop which has the necessary specialist knowl-
edge and tools to carry out the work required.122

Lights and windshield wipers

If the wiper blades are worn, the windshield will
no longer be wiped properly. This could prevent
you from observing the traffic conditions.
Replacing the wiper blades
Important safety notes
G WARNING
If the windshield wipers begin to move while
you are changing the wiper blades, you could
be trapped by the wiper arm. There is a risk of
injury.
Always switch off the windshield wipers and
ignition before changing the wiper blades.
! Never open the hood/tailgate if a wiper arm
has been folded away from the windshield/
rear window.
Never fold a windshield wiper arm without a
wiper blade back onto the windshield/rear
window.
Hold the windshield wiper arm firmly when
you change the wiper blade. If you release the
wiper arm without a wiper blade and it falls
onto the windshield/rear window, the wind-
shield/rear window may be damaged by the
force of the impact.
Mercedes-Benz recommends that you have
the wiper blades changed at a qualified spe-
cialist workshop.
! To avoid damaging the wiper blades, make
sure that you touch only the wiper arm of the
wiper.

G WARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect,
for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk
of an accident.
Do not switch off the ignition while driving.
G WARNING
If the parking brake has not been fully
released when driving, the parking brake can: R
overheat and cause a fire R
lose its hold function.
There is a risk of fire and an accident. Release
the parking brake fully before driving off.
! Do not warm up the engine with the vehicle
stationary. Drive off immediately. Avoid high
engine speeds and driving at full throttle until
the engine has reached its operating temper-
ature.
Only shift the automatic transmission to the
desired drive position when the vehicle is sta-
tionary.
Where possible, avoid spinning the drive
wheels when pulling away on slippery roads.
You could otherwise damage the drive train.
! Mercedes-AMG vehicles: at low engine oil
temperatures below 68 ‡ (+20 †), the max-
imum engine speed is restricted in order to
protect the engine. To protect the engine and
maintain smooth engine operation, avoid driv-
ing at full throttle when the engine is cold.

Vehicles with AIRPANEL: you can open the
shutters in the radiator trim by turning the
SmartKey to position 2 in the ignition lock. After
approximately 120 seconds the shutters open
automatically. Further information on opening
and cleaning the shutters ( Y
page 339).
Start/Stop button
General notes
When you insert the Start/Stop button into the
ignition lock, the system needs approximately
two seconds recognition time. You can then use
the Start/Stop button.
Pressing the Start/Stop button several times in
succession corresponds to the different key
positions in the ignition lock. This is only 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 Smart-
Key determines whether a valid SmartKey is in
the vehicle. This occurs, for example, when
starting the engine.146

movement of the hood.
Open and close the hood only when no one is
within its range of movement.
G WARNING
Opening the hood when the engine is over-
heated or when there is a fire in the engine
compartment could expose you to hot gases
or other service products. There is a risk of
injury.
Let an overheated engine cool down before
opening the hood. If there is a fire in the
engine compartment, keep the hood closed
and contact the fire department.
G WARNING
