X
To switch on or off: press the0033button.
When the automatic interior lighting control is
activated, the button is flush with the over-
head control panel.
The interior lighting automatically switches on if you:
R unlock the vehicle
R open a door
R switch off the engine with the Start/Stop but-
ton
The interior lighting is activated for a short time
when the engine is switched off with the Start/ Stop button. This delayed switch-off can be
adjusted via the multimedia system (see Digital
Operator's Manual). Replacing bulbs
The front and rear light clusters of your vehicle
are equipped with LED light bulbs. Do not
replace the bulbs yourself. Contact a qualified
specialist workshop which has the necessary
specialist knowledge and tools to carry out the
work required.
Lamps are an important aspect of vehicle safety.
You must therefore make sure that these func-
tion correctly at all times. Have the headlamp
setting checked regularly. Windshield wipers
Switching the windshield wipers
on/off
! Do not operate the windshield wipers when
the windshield is dry, as this could damage
the wiper blades. Moreover, dust that has col- lected on the windshield can scratch the glass
if wiping takes place when the windshield is
dry.
If it is necessary to switch on the windshield
wipers in dry weather conditions, always use
washer fluid when operating the windshield
wipers.
! If the windshield wipers leave smears on the
windshield after the vehicle has been washed
in an automatic car wash, wax or other resi-
dues may be the reason for this. Clean the windshield using washer fluid after washing
the vehicle in an automatic car wash.
! Intermittent wiping with rain sensor: due to
optical influences and the windshield becom- ing dirty in dry weather conditions, the wind-
shield wipers may be activated inadvertently.
This could then damage the windshield wiper blades or scratch the windshield.
For this reason, you should always switch offthe windshield wipers in dry weather. 0047

X Switch on the ignition.
X Turn the combination switch to the corre-
sponding position.
In the 0062or0063 position, the appropriate
wiping frequency is set automatically according
to the intensity of the rain. In the 0063position,
the rain sensor is more sensitive than in
the 0062 position, causing the windshield wiper
to wipe more frequently.
The rain sensor is only an aid. The driver is
responsible for ensuring unimpaired vision. Turn
the switch to a suitable position, depending on
the intensity of the precipitation, to ensure that a good view of the traffic conditions is main-
tained.
If the wiper blades are worn, the windshield willno longer be wiped properly. This could preventyou from observing the traffic conditions.
Worn or damaged wiper blades cause smearing. This can cause the rain sensor to malfunction 100

Do not warm up the engine while stationary.
Pull away immediately. Avoid high engine
speeds and full throttle until the engine has
reached its operating temperature.
In vehicles with automatic transmission,
engage positions P and R only when the vehi-
cle is stationary.
Where possible, avoid spinning the drive
wheels when pulling away on slippery roads.
You could otherwise damage the drive train.
! During a cold start with low engine oil tem-
peratures (below 32 ‡) (0 †), the maximum
engine speed is restricted in order to protect
the engine. To protect the engine and main-
tain smooth engine operation, avoid driving at full throttle when the engine is cold. Key positions
Start/Stop button General notes
All vehicles are equipped with a Start/Stop but-
ton.
The Start/Stop button is located in the center
console and is illuminated when the vehicle is
unlocked.
The SmartKey must be in the vehicle.
Pressing the Start/Stop button several times in succession corresponds to the different Smart-
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.
If there is a SmartKey in the ignition lock, this
takes precedence over the KEYLESS-GO start
function.
To start the vehicle without actively using the
SmartKey:
R the SmartKey must be in the vehicle
R the vehicle must not be locked with the
SmartKey or KEYLESS-GO (Y page 67)Do not keep the SmartKey:
R with electronic devices, e.g. a mobile phone
or another SmartKey
R with metallic objects, e.g. coins or metal foil
R inside metallic objects, e.g. a metal case
This can affect the functionality of the Smart-
Key.
If you lock the vehicle with the SmartKey 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 no longer 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 button
on the driver's door (Y page 72), you can con-
tinue to start the engine with the Start/Stop
button.
The engine can be switched off while the vehicle
is in motion by pressing and holding the Start/
Stop button for three seconds. This function
operates independently of the ECO start/stop
automatic engine switch-off function.
Key positions with the Start/Stop button As soon as the ignition is switched on, all the
indicator lamps in the instrument cluster light
up. Further information on situations where an
indicator lamp either fails to go out after starting the engine or lights up while driving
(Y page 200).
If Start/Stop button 0043has not yet been
pressed, this corresponds to the SmartKey
being removed from the ignition.
X To switch on the power supply: press
Start/Stop button 0043once.
The power supply is switched on. You can now
activate the windshield wipers, for example. If you press Start/Stop button 0043twice in this 110

Observe the following rules when driving on salt-
treated roads:
R In order to prevent any salt build-up, apply the
brakes occasionally while paying attention to
the traffic conditions.
R Carefully depress the brake pedal and the
beginning and end of a journey.
R Maintain a greater distance to the vehicle
ahead.
Servicing the brakes !
The brake fluid level may be too low, if:
R if the red brake warning lamp lights up in
the instrument cluster and
R you hear a warning tone while the engine is
running
Observe additional warning messages in the
multifunction display.
The brake fluid level may be too low due to
brake pad wear or leaking brake lines.
Have the brake system checked immediately. Consult a qualified specialist workshop to
arrange this.
All checks and maintenance work on the brake
system must be carried out at a qualified spe-
cialist workshop.
Have brake pads installed and brake fluid
replaced at a qualified specialist workshop.
If the brake system has only been subject to
moderate loads, you should test the functional-
ity of your brakes at regular intervals.
Information on BAS (Brake Assist) (Y page 59).
For safety reasons, Mercedes-Benz recom-
mends only installing the following brake disks
and brake pads/linings:
R brake disks that have been approved by
Mercedes-Benz
R brake pads/linings that have been approved
by Mercedes-Benz or that are of an equivalent
standard of quality
Other brake disks or brake pads/linings can
compromise the safety of your vehicle.
Always replace all brake disks and brake pads/
linings on an axle at the same time. Always
install new brake pads/linings when replacing
brake disks.
The vehicle is equipped with lightweight brake
disks to which the wheel assembly with rim and threaded connection is matched. The use of brake disks other than those
approved by Mercedes-Benz can change the
track width and is subject to approval, if appli-
cable.
Shock-type loads when handling the brake
discs, such as when changing wheels, can lead
to a reduction in comfort when driving with light-
weight brake discs. Avoid shock-type loads on
the lightweight brake disks, particularly on the
brake plate.
Mercedes-Benz recommends that you only use
brake fluid that has been specially approved for your vehicle by Mercedes-Benz, or which corre-
sponds to an equivalent quality standard. Brake fluid which has not been approved for
Mercedes-Benz vehicles or which is not of an
equivalent quality could affect your vehicle's
operating safety.
AMG high-performance and ceramic
brakes The AMG brake systems are designed for heavy
loads. This may lead to noise when braking. This
will depend on:
R Speed
R Braking force
R Environmental conditions, such as tempera-
ture and humidity
The wear of individual components of the brake system, such as the brake pads/linings or brake
discs, depends on the individual driving style
and operating conditions.
For this reason, it is impossible to state a mile-
age that will be valid under all circumstances. An aggressive driving style will lead to high wear.
You can obtain more information on this from a qualified specialist workshop.
New and replaced brake pads and discs only
reach their optimum braking effect after several
hundred kilometers of driving. Compensate for
this by applying greater force to the brake pedal.
Keep this in mind, and adapt your driving and
braking accordingly during this break-in period.
Excessive heavy braking results in correspond-
ingly high brake wear. Observe the brake wear
warning lamp in the instrument cluster and note
any brake status messages in the multifunction
display. Especially for high performance driving,
it is important to maintain and have the brake
system checked regularly. Driving tips
