Technical data
Applies to vehicles: with xenon headlight bulbsDynamic headlight range controlHeadlights with xenon gas-discharge bulbs automatically adapt to
suit the load being carried when the engine is switched on. The
headlights are also automatically adjusted when the vehicle is in
motion (e.g. when accelerating and braking).Applies to vehicles: with adaptive lightadaptive light
This feature provides better illumination when you drive
through a corner.The adaptive light gives better illumination of the bend and the side
of the road when driving through a corner ⇒fig. 59. The adaptive
light is controlled automatically, depending on the speed of the
vehicle and the steering wheel angle.
The headlights are regulated automatically when you drive through
a corner, depending on how far you turn the steering wheel. To
avoid having a dark spot in front of the vehicle the two headlights
are directed at different angles.
Note
The system is active at speeds from approximately 10 km/h to
110 km/h.Hazard warning lights

The hazard warning lights ar e used to make other road
users aware of your vehicle in hazardous situations.– Press the switch
 to switch the hazard warning lights
on or off ⇒fig. 60.
All four turn signals flash simultaneously when the hazard warning
lights are switched on. The two turn signal indicator lamps
  and
the indicator lamp in the switch
 will flash at the same time. The
hazard warning lights also work when the ignition is switched off.
The hazard warning lights come on automatically in the event of an
accident in which an airbag is triggered or in the case of an emer-
gency stop (full br ake application).
Note
You should switch on the hazard warning lights to warn other road
users, for instance:

additional mirrors fitted. Both exterior mirrors should be mounted
on hinged extension brackets. Adjust the mirrors to give sufficient
vision to the rear.
Headlights
Before starting a journey, check
the headlight beam settings with
the trailer hitched up. If necessary, alter the height of the headlight
beams by means of the headlight range control ⇒page 60 .
Power supply
When you remove the ignition key the power supply to the trailer is
interrupted.
Removable ball joint coupling
Vehicles with a factory-fitted towing bracket are equipped with a
removable ball joint coupling. It is carried under the floor panel on
the left-hand side of the luggage compartment and is secured by a
strap.
Note
We recommend having the car serviced between the normal inspec-
tion intervals if it used frequently for towing a trailer.Applies to vehicles: with towing bracketTrailer stabilisation system
Trailer stabilisation helps to reduce the risk of the vehicle
skidding when towing a trailer.The trailer stabilisation system is operational only when the ESP is
switched on and there is no malfunction in the ESP ⇒page 17 .
When is the trailer stab ilisation system activated?
Trailer stabilisation is active when the following requirements are
met:•
The ESP must NOT be switched off ⇒page 222 ,
•
The trailer connector must be properly secured in the vehicle
socket.
•
Vehicle speed must be higher than approx. 60 km/h.
How trailer stabilisation works:
In many cases, the driver can stabilise a swaying trailer by manually
braking the vehicle.
However, if the ESP detects that th e trailer is swaying and this is
affecting the towing vehicle, it will automatically brake the vehicle
to stabilise the trailer by slowing it down. The warning lamp
 will
light up in the instrument cluste r. If possible, do not turn the
steering wheel at this stage.
In order to warn traffic behind you, the brake lights will come on
during this automatic braking operation.
A trailer weighing less than 70% of the kerb weight of the towing
vehicle may sway quite considerably without the trailer stabilisation
system intervening. This can happen when the swaying movements
of the light-weight trailer are not or hardly passed on to the towing
vehicle and are therefore not detected by the ESP.
If the system for activating the trai ler brake lights is defective, this
will be indicated in the instrument cluster display ⇒page 37, “Bulb
monitor ”.
Requirements for correct functioning of the trailer
stabilisation system
If these conditions are not met in full, the trailer stabilisation system
will only intervene to a limited extent or not at all ⇒.
•
The electrical connection between the towing vehicle and the
trailer must be functioning correctly, without any defects.
•
The load on the trailer must be properly secured.
•
The tyre pressures on both the vehicle and the trailer must be
adapted to the load that is being carried.
•
Where possible, operate the trai ler with the maximum permitted
draw bar weight.

battery.
•
Never use a damaged battery - risk of explosion! Replace a
damaged battery immediately.Caution
•
Never disconnect the car's battery with the engine running or
with the ignition turned on, otherwise the electrical system or elec-
trical components will be damaged.
•
Do not expose the battery to direct sunlight over a long period of
time, as the intense ultraviolet radiation can affect the battery
housing.
•
If the car is left standing for long periods, protect the battery
from extreme cold temperature so that it does not “freeze up” and
become damaged.
