General notes G
WARNING
If you leave children unattended in the vehi-
cle, they may be able to set the vehicle in
motion if, for example, they:
R release the parking brake
R shift the automatic transmission out of park
position Por shift manual transmission into
neutral
R start the engine
In addition, they may operate vehicle equip-
ment and become trapped. There is a risk of
an accident and injury.
When leaving the vehicle, always take the key with you and lock the vehicle. Never leave
children unattended in the vehicle.
The function of the electric parking brake is
dependent on the on-board voltage. If the on-
board voltage is low or the system is malfunc-
tioning, it may not be possible to apply the
released parking brake. X If this is the case, park the vehicle only on
level ground and secure it to prevent it from
rolling away.
X Vehicles with automatic transmission:
shift the automatic transmission to position
P.
X Vehicles with manual transmission:
engage first gear.
It may not be possible to release an applied
parking brake if the on-board voltage is low or if
there is a malfunction in the system. Contact a
qualified specialist workshop.
The electric parking brake carries out a function check at regular intervals when the engine is
switched off. Noises that occur are normal. Applying or releasing manually X

vide assistance in the following situations:
R on very sharp corners
R when a loss of tyre pressure or a defective
tyre has been detected and displayed
Also observe the important safety notes for
DISTRONIC PLUS (Y page 171).
The steering interventions are carried out with a limited steering moment. The system requires
the driver to keep his hands on the steering
wheel and to steer himself.
If you do not steer yourself or if you take your
hands off the steering wheel for a prolonged
period of time, the system will first alert you with
a visual warning. A steering wheel symbol
appears on the multifunction display. If you have still not started to steer and have not taken hold
of the steering wheel after five seconds at the
latest, a warning tone also sounds to remind you
to take control of the vehicle. Steering Assist
and Stop&Go Pilot switch to passive mode.
DISTRONIC PLUS remains activated.

179Driving and parking Z

Active Parking Assist will detect only parking
spaces:
R parallel or at right angles to the direction of
travel
R that are parallel to the direction of travel and
are at least 1.5 m wide
R that are parallel to the direction of travel and
at least 1.0 m longer than your vehicle
R that are at right angles to the direction of
travel and at least 1.0 mwider than your vehi-
cle
i Note that Active Parking Assist cannot
measure the size of a parking space if it is at
right angles to the direction of travel. You will need to judge whether your vehicle will fit in
the parking space.
When driving at speeds below 30 km/h, you will
see parking symbol ;as a status indicator in
the instrument cluster. When a parking space
has been detected, an arrow towards the right or the left also appears. Active Parking Assist dis-
plays only parking spaces on the front-
passenger side as standard. Parking spaces on
the driver's side are displayed as soon as the
turn signal on the driver's side is activated.
When parking on the driver's side, this must
remain activated until you confirm the use of
Active Parking Assist by pressing the abut-
ton on the multifunction steering wheel. The
system automatically determines whether the
parking space is parallel or at right angles to the
direction of travel.
A parking space is displayed while you are driv- ing past it, and until you are approximately 15 m
away from it.

G
WARNING
If you uncouple a trailer with an engaged over- run brake, you could trap your hand between
the vehicle and the trailer drawbar. This poses a risk of injury.
Do not uncouple a trailer with an engaged
overrun brake. G
WARNING
Vehicles with level control:
If you disconnect the trailer cable, the vehicle is lowered. This can cause you or others to
become trapped between the vehicle body
and tyres, or underneath the vehicle. This
poses a risk of injury.
Make sure that no-one is in the immediate
vicinity of the wheel arch or underneath the
vehicle when disconnecting the trailer cable.
! Do not disconnect a trailer with an engaged
overrun brake. Otherwise, your vehicle could
be damaged by the rebounding of the overrun
brake.
! Remove the installed adapter cable before
folding in the ball coupling. Otherwise, dam-
age may occur to the rear bumper and the
adapter cable.
X Apply the electric parking brake manually.
X Vehicles with manual transmission:

nent power supply up to a maximum of 240 W.
You cannot charge a trailer battery using the
power supply.
When it leaves the factory, your vehicle's trailer
socket is equipped with a permanent power
supply and a power supply that is switched on
via the ignition lock.
The permanent power supply is supplied via
trailer socket pin 9.
The power supply that is switched on via the
ignition lock is supplied via trailer socket pin 10.
The trailer's permanent power supply is
