– Turn the button clockwise +” to increase the brightness of the instrument lighting in dark conditions.
– Turn the button anti-clockwise -” to reduce the bright- ness of the instrument lighting in dark conditions.
– Press the knob in again to prevent the setting from being changed unintentionally.The instrument lighting (dials and needles), the centre console illu-
mination and the illumination of the displays are regulated by a
light sensor incorporated in the instrument cluster. In bright condi-
tions any changes made to the brig htness of the instrument lighting
have no effect.
Note
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 dimme d automatically as the daylight
starts to fade; it is switched off completely when the light condi-
tions become very poor. This function is intended to remind the
driver to switch on the dipped-beam headlights in good time when
light conditions become poor.
Applies to vehicles: with headlight range controlHeadlight range control

When the dipped beam headlights are switched on, the
range of the headlights can be adjusted to suit the load
being carried.– Turn the thumbwheel
 ⇒ fig. 58 to the appropriate
setting.

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.

Care of vehicle and cleaning245
Controls
Safety
Driving tips

Technical data
WARNING
•
Do not wash the vehicle with the ignition switched on – risk of
accident.
•
Do not clean the underside of th e car or inside the wheel arches
without protecting your hands and arms. You may cut yourself on
sharp metal parts.
•
Take care when washing the car during the winter: moisture
and ice on the brakes may affect braking efficiency – this could
cause an accident.Caution
•
Do not wash the vehicle in direct sunlight – otherwise the paint
can be damaged.
•
Do not use insect sponges or ab rasive household sponges, etc.
– they can damage the surfaces.
•
The headlights should only be washed with water – do not wipe
them with a dry cloth or sponge . It is best to use soapy water.
•
Never wash tyres with a jet that sprays the water out in a direct
stream. This could damage the tyres – even if the spray is kept at a
distance and only used for a very short time.For the sake of the environment
The car should only be washed in special wash bays. This prevents
oily water from getting into the pu blic drains. In some districts,
washing vehicles anywhere else may be prohibited.Waxing and polishingWaxing
Waxing protects the paintwork. It is time to apply a good coat of wax
when water no longer forms droplets and rolls off the clean paint-
work. Even if a
wax solution is used regularly in the car wash, it is advis-
able to protect the paint with a coat of wax at least twice a year.
In the summer, you will find it is much easier to remove dead insects
(which accumulate on the bumper an d the front of the bonnet) if the
car has been waxed recently.
Polishing
Polishing is only necessary if the paint has lost its shine, and the
gloss cannot be brought back by putting on wax.
The car must be waxed after polishing if the polish used does not
contain wax compounds to seal the paint.
Caution
Matt painted and plastic parts mu st not be treated with wax or
polish.Ornamental trim and mouldingsThe metal brightwork on the body is made of aluminium rather than
chrome (for environmental reasons).
Dirt or marks on the trim mouldings should be removed with an
acid-free cleaning agent (do not use a chrome cleaner). Body polish
is also unsuitable for use on trim mouldings. The intensive cleaning
fluids often used before the car goes into a car wash may contain
alkaline substances, which can cause dull or milky patches when
they dry out.
Audi dealers carry stocks of cleaning products which have been
tested for use on your vehicle and are not harmful to the
environment.

Changing bulbs requires a certain degree of practical
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
•
Bulbs for number plate light
The following bulbs should only be changed by a qualified work-
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/parki ng 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.
