Traction Control system
The traction control system is a
component part of the Electronic
Stability Control (ESC) which
improves driving stability when
necessary, regardless of the type of
road surface or tyre grip, by
preventing the drive wheels from
spinning.
As soon as the drive wheels start to
spin, engine output is reduced and
the wheel spinning the most is braked
individually. This considerably
improves the driving stability of the
vehicle on slippery road surfaces.
Traction control system is operational as soon as the ignition is switched onand control indicator b extinguishes
in the instrument cluster.

254Driving and operatingpedal to override the automatic
braking if the situation and the
surroundings permit.
In the following cases, active
emergency braking performance is limited:
● driving on winding or hilly roads
● detecting all vehicles, especially vehicles with a trailer, tractors,
muddy vehicles, etc.
● detecting a vehicle when weather
limits visibility, such as in fog,
rain, or snow
● driving during nighttime
● sensor in the windscreen or radar
unit behind the front bumper blocked by snow, ice, slush, mud, dirt, etc.
● windscreen damaged or affected
by foreign objects, e.g. stickers
Complete attention is always required
while driving, and you should be
ready to take action and apply the
brakes and / or steer the vehicle to
avoid crashes.Fault
In case the system requires a service, a message is displayed in the Driver
Information Centre.
Additionally, warning lights l and
j illuminate at the same time.
When the system detects that its
function is not available, warning light
l or j illuminates and stays on.
Additionally, a message in the Driver
Information Centre appears. The system may be temporarily disrupted
(for example: radar or camera
obscured by dirt, mud, snow etc.). In
this case, park the vehicle and switch off the engine. Clean the windscreen
area around the camera and the
detection zone of the radar in the front bumper. When the warning lights and
messages still appear after starting
the vehicle again, seek the
assistance of a workshop.Parking assist9 Warning
It is the driver who bears full
responsibility for the parking
manoeuvre.
Always check the surrounding
area while reversing and using the rear parking assist system.
The parking assist measures the
distance between the vehicle and
obstacles behind and, if available, in
front of the vehicle. It informs and
warns the driver by giving acoustic
signals.
The system consists of four ultrasonic parking sensors in the rear bumper
and, if available, four ultrasonic
parking sensors in the front bumper.
Driving and operating257Deactivation
To deactivate the system, press .
with the ignition on. The LED in the
button illuminates when deactivated.
To reactivate the system, press .
again. The LED in the button
extinguishes.
Functionality
When the system detects a vehicle in the side blind zone while driving
forwards, an LED will illuminate in the
relevant exterior mirror.
The LED comes on immediately when being passed.
The LED comes on after a delay when
passing another vehicle slowly.
The LED flashes when the turn lights
are activated and a vehicle is
detected.
Operation conditions
The following conditions must be
fulfilled for proper operation:
● all vehicles are moving in the same direction and in adjacent
lanes
● the speed of your vehicle is between 19 mph and 87 mph
● the traffic flow is normal
● driving on a straight or slightly curved road
● the vehicle is not pulling a trailer ● the sensors are not covered by mud, ice or snow
● the warning zones in the exterior mirrors or the detection zones in
front and rear bumper are not
covered
No alert will be given in the following
situations:
● in the presence of non-moving objects, e.g. parked vehicles,
barriers, street lamps, road signs
● with vehicles moving in the opposite direction
264Driving and operatingTrailer hitch
General information
Only use towing equipment that has
been approved for your vehicle.
Entrust fitting of towing equipment at
a later date to a workshop. It may be
necessary to make changes that
affect the cooling system, heat
shields or other equipment.
Driving characteristics and towing tips
In the case of trailers with brakes,
attach the breakaway stopping cable.
Before attaching a trailer, lubricate
the coupling ball. However, do not do so if a stabiliser, which acts on thecoupling ball, is being used to reduce
snaking movements. For trailers with
low driving stability the use of a
stabiliser is recommended.
A maximum speed of 50 mph must
not be exceeded, even in countries
where higher speeds are permitted.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 3 315.
Trailer towing
Trailer loads The permissible trailer loads are
vehicle-dependent and engine-
dependent maximum values which
must not be exceeded. The actual
trailer load is the difference between
the actual gross weight of the trailer
and the actual coupling socket load
with the trailer coupled.
The permissible trailer loads are
specified in the vehicle documents. In
general, they are valid for gradients
up to max. 12%.
The permitted trailer load applies up to the specified incline and up to an
altitude of 1000 m above sea level.Since engine power decreases as
altitude increases due to the air
becoming thinner, therefore reducing
climbing ability, the permissible gross
train weight also decreases by 10%
for every 1000 m of additional
altitude. The gross train weight does
not have to be reduced when driving
on roads with slight inclines (less than 8%, e.g. motorways).
The permissible gross train weight
must not be exceeded. This weight is
specified on the identification plate
3 314.
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 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.
Driving and operating265In the case of trailer loads of
1200 kg or more, the vertical coupling
load should not be less than 50 kg.
Rear axle loadWhen the trailer is coupled and the
towing vehicle fully loaded (including all occupants), the permissible rear
axle load (see identification plate or
vehicle documents) can be exceeded
by 15%. If the permissible rear axle
load is exceeded, a maximum speed of 48 mph applies and the tyre
pressure must be increased by 20
kPA / 3 psi.
Towing equipment For vehicles fitted with towing
equipment, when connected to a
trailer the pitch of the audible warning
changes upon operation of the turn
lights.
The pitch of the audible warning will
change if a turn light on the trailer or
the towing vehicle fails.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 the system is working,
keep steering wheel as still as
possible.
Trailer stability assist is a function of
the Electronic Stability Control (ESC)
