Note
•
The needles in the instrument cluster will sweep across the dials
when you switch on the ignition.
•
The instrument lighting (illumination of dials and needles) is
switched on when the ignition is on and the vehicle's lights are off.
The instrument lighting is dimmed automatically as the daylight
starts to fade. This function is intended to remind the driver to
switch on the dipped-beam headlights in good time when light
conditions become poor.
Coolant temperature gaugeThe coolant temperature gauge ⇒fig. 2 only works when the
ignition is switched on. In order to avoid possible damage to the
engine, please read the following notes for the different tempera-
ture ranges.
Engine cold
If the needle is still in the lower range of the dial, this indicates that
the engine has not yet reached operating temperature. Avoid high
engine speeds, full acceleration and heavy engine loads.
Normal temperature
In normal operation the needle will settle somewhere in the centre
of the dial once the engine has reached operating temperature. The
needle may also go further up when the engine is working hard at
high outside temperatures. This is no cause for concern provided
the warning symbol
in the display does not start flashing.

Technical data 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 stabilisation 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 the 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 cluster. 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 trailer 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 trailer with the maximum permitted
draw bar weight.

skill.You can change the following bulbs for exterior lights yourself:•
Halogen headlights: Bulb for dipped headlights
•
Halogen headlights: Bulb for main beam headlights
•
Bulb for fog light
•
Bulbs for rear lights in boot lid
•
Bulbs for rear lights in side panel

shop:
•
Halogen headlights: Bulb for turn signals
•
Halogen headlights: Bulb for side lights
•
Xenon headlights*: Bulb for turn signals
•
Xenon headlights*: Light source for daytime running
lights/parking lights
•
Bulb for headlights: Bi-xenon lights ⇒
•
Light source for turn signal in exterior mirror housing
•
Light source for high-level brake light
As a rule, you require a certain degree of practical skill to change
defective bulbs. This applies in particular to those bulbs which are
only accessible from the engine compartment.
If in doubt, we recommend that you have defective bulbs changed
by a qualified workshop or qualified mechanic.
If you do decide to change bulbs in the engine compartment your-
self, be aware of the safety risks involved ⇒page 255 ⇒.
Types of bulbs
You must only replace a bulb with a bulb of the same type. Informa-
tion regarding e.g. the wattage can be found on the base of the
bulb.
