194Driving and operating
An illuminated LED in the parking
assist button r indicates that the
system is ready to operate.
If the vehicle exceeds a speed of
7 mph, the front parking assist is
deactivated. The front parking assist
is always reactivated when vehicle
speed drops below 7 mph.
Indication
The system warns the driver with
acoustic signals against potentially
hazardous obstacles behind and in
front of the vehicle. Depending on
which side of the vehicle is closer to
an obstacle, you will hear acoustic
warning signals on the respective
side of the vehicle. The interval
between the sounds becomes shorter as the vehicle gets closer to that
obstacle. When the distance is less
than approx. 30 cm, the sound is
continuous.
Additionally, the distance to obstacles is shown in the Driver Information
Centre 3 111.
The distance to a front and rear
obstacle is indicated by changing
distance lines around the vehicle.
Rear obstacles are indicated
acoustically and visually at the same
time.
Front obstacles are indicated visually
first. At distances less than 80 cm an
acoustic signal also sounds.
The distance indication in the Driver
Information Centre can be inhibited
by vehicle messages with a higher
priority. After approving the message
by pressing the SET/CLR button on
the turn signal lever or 9 on right
steering wheel control, distance
indication appears again.
Deactivation
The rear parking assist automatically
switches off when reverse gear is
disengaged.
The front parking assist is deactivated
automatically at a speed above
7 mph.

General information
The factory-fitted towing equipment is
folded up under the rear bumper
fascia.
Entrust retrofitting of towing
equipment to a workshop. It may be
necessary to make changes that
affect the cooling system, heat
shields or other equipment. Only use
towing equipment that has been
approved for your vehicle.
To avoid vehicle damage, the power
tailgate cannot be operated with the
radio remote control when a trailer is
electrically connected.
Fitting of towing equipment could
cover the opening of the towing eye. If this is the case use the coupling ball
bar for towing.Driving characteristics and
towing tips Before attaching a trailer, lubricate
the coupling ball. However, do not do
so if a stabiliser, which acts on the coupling ball, is being used to reduce snaking movements.
For trailers with low driving stability
and trailers with a permitted gross
vehicle weight of more than 1400 kg
(Front-wheel drive)/1600 kg (All-
wheel drive) the use of a stabiliser is
strongly recommended when driving
above 50 mph.
If the trailer starts snaking, drive more slowly, do not attempt to correct the
steering and brake sharply if
necessary.
When driving downhill, drive in the
same gear as if driving uphill and
drive at a similar speed.
Adjust tyre pressure to the value
specified for full load 3 293.

A buzzing tone sounds as a warning
when the release handle is pulled out and the ball neck is disengaged.
With the flat of the hand, swivel the
released coupling ball bar to the right
until it engages under the floor. Make sure that the release handle is back inits hidden initial position, otherwise
the buzzing tone will not stop.9 Warning
Towing a trailer is permitted only
when the coupling ball bar is fitted correctly. If the coupling ball bar
does not engage correctly or if the
release handle is impossible to guide to its hidden initial position in the housing or if the buzzing tone
sounds after engaging the
coupling ball bar, seek the
assistance of a workshop.
Eye for break-away stopping cable
Attach break-away stopping cable to
eye.
Trailer stability assist
If the system detects snaking
movements, engine power is reduced and the vehicle/trailer combination is
selectively braked until the snaking
ceases. While system is working keep
steering wheel as still as possible.
Trailer stability assist (TSA) is a
function of the Electronic Stability
Control 3 173.
