Technical data It is also important for the rear passengers to wear seat belts, as
they could otherwise be thrown forwards violently in an accident.
Rear passengers who do not use seat belts endanger not only them-
selves but also the other occupants ⇒page 162, fig. 170.
How to wear seat belts properlyPutting on the three-point seat belts
Always fasten your seat belts before driving off.– Adjust the front seat and head restraint correctly before
putting on the seat belt ⇒page 70, “Seats and storage”.– To fasten the belt, take hold of the latch plate and pull it
slowly across your chest and lap ⇒.
– Insert the latch plate into the buckle for the appropriate
seat and push it down until it is securely locked with an
audible click ⇒fig. 172.
– Pull the belt to check that it is now securely fastened.
The three-point inertia reel belts are tensioned automatically. The
retractor system gives complete freedom of movement, as long as
the pull on the belt is slow. Hard braking locks the belt. The belt will
also lock when you accelerate, drive up or down a steep hill or in a
sharp curve.
WARNING
•
Always make certain that the belt is positioned properly
⇒fig. 171 – risk of injury ⇒page 163, “Adjusting the seat belts”.
•
The latch plate of the belt must always be engaged in the
correct buckle for that seat. Otherwise the belt will not be fully
effective and the danger of injury increases.
Adjusting the seat belts
Always position seat belts properly for maximum safety.

Downloaded from www.Manualslib.com manuals search engine Seat belts 164The height of the front seat on your vehicle can be adjusted in order
to match the position of the seat belt to your height.
WARNING
•
The diagonal part of the belt should never be positioned across
the neck, but roughly over the centre of the shoulder; it should fit
closely against the upper part of the body. The lap part of the belt
must be worn tightly across the hips, and not over the abdomen
⇒page 163, fig. 173. Pull the belt tight if necessary to take up any
slack.
•
Always make sure that belt is positioned properly. Incorrectly
worn seat belts can give rise to injuries even in a minor collision.
•
Seat belts worn too loose can result in injuries because they
allow excessive forward movement in a crash; the occupant will
be brought to a sudden stop by the belt webbing.
Wearing and adjusting the seat belts during pregnancy
To afford the best protection for the unborn child it is
important for the mother to wear the seat belt properly at
all times.
Women should always ensure they adjust the seat belt
correctly during pregnancy.
– Adjust the front seat and head restraint correctly before
putting on the seat belt ⇒page 70, “Seats and storage”.
– To fasten the belt, take hold of the latch plate and pull it
slowly down across your chest. Wear the lap portion of
the seat belt as low as possible over the hips so that there
is no pressure on the stomach ⇒fig. 174, ⇒.
– Insert the latch plate into the buckle for the appropriate
seat and push it down until it is securely locked with an
audible click ⇒page 163, fig. 172.
– Pull the belt to check that it is now securely fastened.
WARNING
During pregnancy, women should especially make sure to wear
the lap portion of the seat belt as low as possible across the hips
so that there is no pressure on the stomach.Taking off the seat belts

Possible alternatives for securing a child safety seat
A child safety seat can be secured on the rear seats and
on the front passenger's seat.The following alternatives are available for safely securing a child
safety seat on the rear seats and on the front passenger's seat.•
Child safety seats of the categories 0 to 3 can be secured with the
standard three-point seat belts.
•
Child safety seats of the categories 0, 0+ and 1 with the “ISOFIX”
system can be secured without seat belts using the “ISOFIX”
retainers* ⇒page 181.
Compatibility of vehicle seat positions for child safety seats
(according to EC directive 77/541):
“universally compatible”
The front passenger's backrest must be set as far forward as
possible or adapted to the child safety seat as required, and the
seat height must be adjusted to its highest position.
The front passenger's airbag must be deactivated if a rearward-
facing child seat is used.
The front passenger's seat can be equipped with optional
“ISOFIX” retainers.
The rear seats can be equipped with optional “ISOFIX” retainers.
WARNING

Downloaded from www.Manualslib.com manuals search engine Towing a trailer 198Towing a trailerDriving the vehicle with a trailer or
caravanTechnical requirements
The towing bracket must comply with certain technical
requirements.Your car is intended mainly for transporting passengers and
luggage. However, if suitably equipped, it can also be used to tow a
trailer or caravan.
If the car is supplied with a factory-fitted towing bracket it will
already have the necessary technical modifications and meet the
statutory requirements.
A 13-pin socket is provided to make the electrical connection
between the car and the trailer. If the trailer has a 7-pin plug you can
use an adapter cable. This is available from Audi dealers.
WARNING
If a towing bracket is retrofitted, the installation should be carried
out by a qualified workshop.•
In particular in high outside temperatures it is not possible to
drive up long steep gradients without a suitable cooling system.
The engine would then overheat.
•
Incorrect installation can result in a safety risk.
Points to check before towingTrailer weights
Never exceed the maximum permitted trailer weights ⇒page 281.If you do not load the trailer up to the maximum permitted trailer
weight, you can then climb correspondingly steeper gradients.
The maximum trailer weights listed are only applicable for altitudes
up to 1000 m above sea level. With increasing altitude the engine
power and therefore the car's climbing ability are impaired because
of the reduced air density, so the maximum trailer weight has to be
reduced accordingly. The weight of the car and trailer must be
reduced by 10% for every further 1000 m (or part thereof). This
figure refers to the combined weight of the (loaded) vehicle and
(loaded) trailer.
The figures for the draw bar weight that appear on the identification
plate of the towing bracket are for certification purposes only. The
correct figures for your specific vehicle, which may be lower than
these figures for the towing bracket, are given in the registration
documents. Also refer to ⇒page 281.
Distributing the load
Distribute loads in the trailer so that heavy objects are as near to the
axle as possible. Loads carried in the trailer must be secured to
prevent them slipping.
Where possible, operate the trailer with the maximum permitted
draw bar weight on the ball joint of the towing bracket, but do not
exceed the specified limit.
Tyre pressure
Check the tyre pressures on your car and adjust for “full load” condi-
tions (refer to the sticker listing the tyre pressures on the end face
of the driver's door). It may also be necessary to adjust the tyre pres-
sures on the trailer according to the recommendations of the trailer
manufacturer.
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

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.
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.
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.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 186,
•
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 36, “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.
•
The trailer overrun brake must be set correctly. This is important
to ensure that the trailer can be braked correctly, to avoid the vehicle
and trailer “jack-knifing” and to prevent excess braking of the trailer.
•
In low outside temperatures, both the towing vehicle and the
trailer should be fitted with winter tyres.
