Parking assist
Rear parking assist9 Warning
The driver bears full responsibility
for the parking manoeuvre.
Always check the surrounding
area while reversing and using the rear parking assist system.
The rear parking assist makes
parking easier by measuring the
distance between the vehicle and
rear obstacles. It informs and warns
the driver by giving acoustic signals.
The system has four ultrasonic
parking sensors in the rear bumper.
Activation
When reverse gear is engaged, the
system is ready to operate
automatically.
An illuminated LED in the parking
assist button r indicates that the

Page 170 of 263

168Driving and operatingThe maximum allowed parallel
distance between the vehicle and a
row of parked cars is 1.8 metres.
Functionality
When the vehicle passes a row of
cars and the system is activated, the
advanced parking assist system
begins searching for a suitable
parking slot. When a suitable slot is
detected, visual feedback in the
Driver Information Centre and an
acoustic signal are given.
If the driver does not stop the vehicle
within 10 metres after a parking slot is
proposed, the system starts to search for another suitable parking slot.
The parking slot suggestion of the
system is accepted when the vehicle
is stopped by the driver within
10 metres after the "Stop" message is
given. The system calculates the
optimal route into the parking slot.
Then it manoeuvres the driver into the slot by giving detailed instructions.The instructions in the display show:
● A hint when driving faster than 30 km/h.
● The demand to stop the vehicle, when a parking slot is detected.
● The direction of driving during the
parking manoeuvre.
● The steering wheel position during parking.
● For some of the instructions a progress bar is shown.

184Driving and operatingThe permissible gross train weight
must not be exceeded. This weight is
specified on the identification plate
3 236.
Vertical coupling load The vertical coupling load is the load
exerted by the trailer on the coupling
ball. It can be varied by changing the
weight distribution when loading the
trailer.
The maximum permissible vertical
coupling load (75 kg) is specified on
the towing equipment identification
plate and in the vehicle documents.
Always aim for the maximum load,
especially in the case of heavy
trailers. The vertical coupling load
should never fall below 25 kg.Rear axle load
When the trailer is coupled and the
towing vehicle fully loaded, the
permissible rear axle load (see
identification plate or vehicle
documents) may be exceeded by 100 kg, the gross vehicle weight
rating may be exceeded by 100 kg. If
the permissible rear axle load is
exceeded, a maximum speed of
100 km/h applies.
