EBD (electronic brake force distribu-
tion)
General notes EBD monitors and controls the brake pressure
on the rear wheels to improve driving stability
while braking.
Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 54). G
WARNING
If EBD is malfunctioning, the rear wheels can
lock, e.g. under full braking. This increases the risk of skidding and an accident.
You should therefore adapt your driving style
to the different handling characteristics. Have the brake system checked at a qualified spe-
cialist workshop.
Observe information regarding indicator and
warning lamps (Y page 197) as well as display
messages (Y page 174). ADAPTIVE BRAKE
ADAPTIVE BRAKE enhances braking safety and
offers increased braking comfort. In addition to
the braking function, ADAPTIVE BRAKE also fea-
tures the hill start assist function (Y page 104).Protection against theft

adjusted via the multimedia system (see the
separate operating instructions). Replacing bulbs
The front and rear light clusters of your vehicle
are equipped with LED bulbs. Do not replace the bulbs yourself. Contact a qualified specialist
workshop with the necessary specialist knowl-
edge and tools to carry out the work required.
The light clusters 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. Windscreen wipers
Switching the windscreen wipers on/
off
! Do not operate the windscreen wipers when
the windscreen is dry, as this could damage
the wiper blades. Moreover, dust that has col-
lected on the windscreen can scratch the
glass if wiping takes place when the wind-
screen is dry.
If it is necessary to switch on the windscreen wipers in dry weather conditions, always
operate them using washer fluid.
! If the windscreen wipers leave smears on
the windscreen after the vehicle has been
washed in an automatic car wash, this may be
due to wax or other residue. Clean the wind-
screen with washer fluid after an automatic
car wash.
! Intermittent wiping with rain sensor: due to
optical influences and the windscreen becom-
ing dirty in dry weather conditions, the wind-
screen wipers may be activated inadvertently. This could damage the windscreen wiper
blades or scratch the windscreen.
For this reason, you should always switch off
the windscreen wipers in dry weather. 1

X Turn the combination switch to the corre-
sponding position.
In the ÄorÅ position, the appropriate
wiping frequency is set automatically according to the intensity of the rain. In the Åposition,
the rain sensor is more sensitive than in the
Ä position, causing the windscreen wiper to
wipe more frequently.
If the wiper blades are worn, the windscreen will no longer be wiped properly. This could mean
you are unable to observe the traffic conditions. Replacing the wiper blades
Important safety notes G
WARNING
If the windscreen wipers begin to move while
you are changing the wiper blades, you can be trapped by the wiper arm. There is a risk of
injury.
Always switch off the windscreen wipers and
ignition before changing the wiper blades.
! Never open the bonnet if a windscreen
wiper arm has been folded away from the
windscreen. 92
