the tyre pressures on the trailer according to
the recommendations of the trailer manufac-
turer.
Exterior mirrors
Check whether you can see enough of the road
behind the trailer with the standard mirrors.
If this is not the case you should have addi-
tional 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. Ad-
just the headlight settings if necessary.
If the car is equipped with manual headlight
range control, you only need to turn the ad-
juster control as required, see
c>
page 54.
The headlight beam settings will be adjusted
automatically if your vehicle is equipped with
dynamic headlight range control*.
Power supply
To ensure that the engine can be started again
after the ignition is switched off, the power
management system c> page 187 controls the
distribution of electrical power and gradually
switches off unnecessary e lectrical equip-
ment. The trailer is s upplied with power dur-
ing this period. The power supply to the trailer
is interrupted while the engine is being star-
ted.
Removable ball joint coupling
Vehicles with a factory-fitted towing bracket
are equipped with a removable ball joint cou-
pling. This is stored in the spare wheel well or
in a separate bag on the floor of the luggage
compartment, together with the necessary
fitting instructions.

Towing a trailer 195
@
Note
We recommend having the car serviced be-
tween the normal inspection intervals if it
used frequently for towing a trailer.
Trailer stabilisation system
Applies to vehicles: with towing bracket
Trailer stabilisation helps to reduce the risk
of the vehicle skidding when towing a trailer.
When is the trailer stabilisation systeml>
activated?
Trailer stabilisation is active when the follow-
ing requirements are met:
- The ESC must be switched on
c>
page 183
and fully functional (no ESC malfunction).
- The trailer connector must be properly se-
cured in the vehicle socket.
- The vehicle speed must be higher than ap-
prox. 60 km/h.
How trailer stabilisation works
In many cases, the driver can stabilise a sway-
ing trailer by manually braking the vehicle.
However, if the ESC detects that the trailer is
swaying and this is affecting the towing vehi-
cle, it will automatically brake the vehicle in
order to stabilise the trailer. The indicator
lamp
m
will flash in the instrument cluster.
If possible, do not turn the steering wheel at
this s tage.
In order to warn traffic behind you, t he brake
lights will come o n during this automatnc
braking operation .
A trailer may sway quite considerably without
the trailer stabilisation system intervening.
This can happen when the swaying
move-
ments of the light-weight trailer are not or
hardly passed on to the towing vehicle and are
therefore not detected by the ESC. .,.
