Trailer lights
Trailer lights must meet all regulations. Be sure to check with your autho rized Audi dealer for correct wiring , switches and relays .
Mirrors
If you are unable to see the traffic behind you using the regular
outside mirrors, then you
must install extended mirrors. It is impor ­
tant that you always have clear vision to the rear .
& WARNING
After removing the trailer hitch, do not store it in your vehicle. In
case of sudden braking, the hitch could fly forward and injure you
or your passengers .

Operating instructions
Maximum trailer weight
A trailer for your vehicle is limited to a typical class 1 or class 2
trailer .
Trailer load distribution
Be sure the load in the trailer is held securely in place to guard
against shifting, be it forward, backward or sideways.
Never allow a passenger to ride in a trailer~&, in "Driving instruc­
tions".
Tire pressure
When towing a trailer, inflate the tires of your vehicle to the cold tire
pressure listed under "Full load" on the sticker on the right door­
jamb. Inflate trailer tires to trailer and tire manufacturers' specifica­
tions.
Controls and equip­ ment Safety first Vehicle operation
Trailer towing
Lights
The
headlight settings should be checked with the trailer attached
before driving off. Adjust as necessary so that you can see the road
ahead but not blind on -coming traffic.
Check proper working of vehicle and trailer lights .
Safety chains
Be sure trailer safety chains are properly connected from the trailer
to the hitch on the vehicle. Leave enough slack in the chains to
permit turning corners. When you install safety chains, make sure
they will not drag on the road when you are driving.
The chains should cross under the trailer tongue to prevent it from
dropping in case of separation from the hitch .•
Driving instructions
Driving with a trailer always requires extra care and
consideration.
To obtain the best possible handling of vehicle and trailer,
please note the following:
Do not tow a loaded trailer when your car itself is not
loaded.
- Be especially careful when passing other vehicles.
Observe speed limits.
Do not drive at the maximum permissible speed.
- Always apply brakes early.
Monitor the temperature gauge.

-Cleaning and protection P':ft':I _______________ _
& WARNING
• Do not clean the underside of the chassis, fenders, wheel
covers, or other hard to reach parts without protecting your hands
and arms. You may cut yourself on sharp-edged metal parts.
• Always read and heed all WARNINGS and other information
~ page 230.
0 Note
• Never try to remove dirt, mud or dust if the surface of the vehicle
is dry. Never use a dry cloth or sponge, since this could scratch your
vehicle's paint or windows.
• Never wash your car in bright sunlight. Drops of water act as
magnifying lenses and may damage your paint .
• When you wash your car in the winter: if you rinse your vehicle
with a hose, be careful not to aim the stream of water directly at
locks, or at door or hatch openings - they can freeze shut.
• Never use sponges designed to remove insects, or any kitchen
scouring sponges or similar products. They can damage your paint
finish .
• Never use a dry cloth or sponge to clean the headlights. Only use
wet cloths or sponges to prevent scratches . It is best to use soapy
water.
<£> For the sake of the environment
In the interest of the environment, the vehicle should only be
washed in special wash bays. •
Washing your vehicle with a power washer
Cleaning the exterior of your car with a high-pressure
power washer is safe as long as you observe a few simple
rules.
- Before using the power washer, make sure you have read
and understood the WARNINGS~
& in "General infor­
mation" on
page 230.
Always follow the operating instructions for the power
washer.
Make sure that the jet on the spray hose produces a "fan
shaped spray".
Do
not hold the spray nozzle too close to soft materials.
When cleaning the vehicle with a power washer always follow the
operating instructions. This applies particularly to the
operating
pressure and the spraying distance. Maintain a sufficient distance
to soft materials such as rubber hoses and sound/vibration dead­ ening materials {particularly on the underside of the engine hood).
Do not use a jet which sprays water in a
direct stream or one that
has a
rotating jet.
Water temperature should not exceed 140
°F (60 °C).
& WARNING
Never wash tires with a jet that sprays water in a direct stream.
This could cause invisible damage to the tires and weaken them,
even if the spray is from a relatively long distance and for a short
time . Damaged and weakened tires can fail and cause accidents
and personal injury.
0 Note
• Never use a power washer to clean the power top itself.

General notes
Tires may be the least appreciated and most abused parts
of a motor vehicle.
Tires may be the least appreciated and most abused parts of a
motor vehicle. Tires are, however, one of the most important parts
of a vehicle, particular ly considering the comparative ly sma ll patch
of rubber on each tire that assures that all -important contact
between you, your vehicle and the road .
Maintaining the correct tire pressure, making sure that your vehicle
and its tires do not have to carry more weight than they can safely
handle, avoiding damage from road hazards and regular ly
inspecting tires for damage inc luding cuts , slashes irregular wear
and overal l condition are the most important things that you can do
to help avoid sudden tire failure including tread separation and
b lowouts .
Avo iding d am age
If you have to drive over a curb or similar obstacle, drive very slowly
and as close as possible at a right angle to the curb.
A lways keep chemica ls including grease, oil, gasoline and brake
flu id off the ti res .
I nspect the tires regularly for damage (cuts, cracks or blisters, etc .!.
Remove any foreign bodies embedded in the treads .
Storing tire s
Mark tires when you remove them to indicate the direction of rota ­
tion. This ensures you to be ab le to mount them correctly when you
reinstall them. When removed, the whee
ls or tires should be stored in a coo l, dry
and preferably dark place.
Store tires in a vertical position i f they are not mounted on r ims, in
a horizontal position if they are mounted on rims.
N ew tire s
New tires have to be broken in => &.
The tread depth of new tires may vary, according to the type and
make of tire and the tread pattern.
Hidd en d am ag e
Damage to tires and rims is often not readily visible . If you notice
unusua l vibration or the vehic le pul ls to one side, this may indicate
that one of the tires has been damaged . The tires must be checked
immediately by an author ized Audi dealer or qualified workshop .
Uni dir ection al tire s
A unidirect ional tire can be identified by arrows on the sidewa ll, that
point in the direction the tire is designed to rotate. You must fo llow
the specified direction of ro tation . This is necessary so that these
tires can deve lop their optimum characteristics regarding grip, road
noise, wear and hydroplaning resistance . For more information
=> page 298.
Rim s with bolted rim ring *
Light-alloy wheels with a bo lted rim ring consist of several parts .
These parts are screwed together with special bo lts, using a specific
technique. This ensures proper function, seal, safety, and true running of the wheel. For this reason, damaged rims shou ld be
replaced, and you should never repair or dismantle them
=> & .
Rim s with screw -on decorative co vers *
Light-a lloy whee ls can be furnished with interchangeab le decora -
tive covers that are mounted to the rim with se lf -locking bolts. ...
Vehic le care

-~_T_ ir_e_ s_ a_ n_d _ w_ h_ e_e _l_s _________________________________________________ _
Contact a dealership if you would like to replace damaged whee l
cove rs.
& WARNING
Never loo sen the screws on rim s with threaded rim rings* -danger
of accident!
& WARNING
New tires or tires that are old , worn or damaged cannot provide
maximum control and braking abil ity .
• New tires tend to be slippery and must be broken in. To reduce
the risk of losing control , a collision and serious per sonal injurie s,
drive with special care for the first 350 miles (560 km ).
Glossary of tire and loading terminology
Accessory weight
means the co mbined we ig ht (in excess o f those standar d ite ms

& W ARNING (continued )
• Driving with worn or damaged tires can lead to loss of control,
sudden tire failure, including a blowout and sudden deflat ion ,
crashes and serious personal injuries . Have worn or damaged tires
replaced immediately.
• Tires age even if they are not being used and can fail suddenly,
e specially at high speeds. Tires that are more than 6 years old can
only be used in an emergen cy and then with special care and at
low speed.
• Never mount used tires on your vehicle if you are not sure of
their "p revious history. " Old used tire s may have been damaged
even though the damage cannot be seen that c an lead to sudden
tire failure and lo ss of vehicle control.
• If you notice unusual vibration or if the vehicle pulls to one side
when driv ing , always stop as soon as it is safe to do so and check
the wheels and tires for damage . •

Uniform Tire Q uality Gra ding
is a tire information system developed by the United States National
Highway Traffic Safety Administration (N HTSA) that is designed to
help buyers make relative comparisons among tires. The U TQG is
not a safety rating and not a guarantee that a tire wil l last for a
prescribed number of miles or perform in a certain way. It simply
gives tire buyers additiona l information to combine wit h other
considerations, such as price, brand loyalty and dea ler recommen­
dations. Under UTQG, tires are graded by the tire manufacturers in
three areas: treadwear, traction and temperature resistance . The

Tire pressure generally refers to the amount of air in a tire that it
needs it to do its job and safely carry the combined load of the entire
vehicle and its contents. Tire pressure is measured in kilopascals (kPa), the internationa l measuring unit and in pounds per square
inch (PSI!. Tire pressure is based in part on the vehic le's design and

warmed up than when it is "cold." It is the inflation pressure in a
"cold" tire that counts. Therefore, you should never let air out of a
warm tire to match "cold tire inflation pressure" recommendations .
The tires would then be underinflated and could fail suddenly.
Maintaining proper tire pressure is one of the most important
things you can do to help avoid sudden tire failure. Underinflated
tires are a major cause of sudden tire failure. Keeping tires at the
right pressure is also important for safe and responsive vehicle
handling, traction, braking and load carrying.
Tire pressures are
particularly important when the vehicle is being driven at higher
speeds, and then especially when heavily loaded even within the
permissible load-carrying capacities approved for your vehicle .
The recommended tire pressures for your Audi depend on the kind
of tires on your vehicle and the number of passengers and/or
amount of luggage you will be transporting.
On USA vehicles, the tire pressure label is located on the driver's
side B-pillar . On Canada vehicles, the tire pressure label is located
either on the driver's side B-pillar or inside the fuel filler flap. The tire
pressure label lists the recommended cold tire inflation pressures
for the vehicle at its maximum capacity weight and tires that were
on your vehicle at the time it was manufactured.
If you wish to improve comfort when operating the vehicle at
normal load (up to 2 occupants), you can adjust tire pressures to
-
those specified for normal vehicle load. Before operating the vehicle
at maximum load, you must increase the tire pressures to those
specified for maximum vehicle load
=> & .
If your vehicle is equipped with a tire pressure monitoring system *,
bear in mind that the system can only monitor the tire pressures you
have stored. The system does not recognize the load condition of
your vehicle.
The effectiveness of the tire pressure monitoring system will be
impaired if you store normal load pressures but then operate the
vehicle at its maximum load=>&.
See the illustration =>
page 271, fig. 207 for the location of the label
either on driver's side B-pillar or inside the fuel filler flap (color of
the actual label and exact location on the vehicle will vary slightly).
Note that the following table is accurate at the time of going to
press and is subject to change. In the event of discrepancies, the tire
pressure label (either on driver's side B-pillar or inside the fuel filler
flap) always takes precedence .
The table below lists the recommended cold tire inflation pressures
for the Audi model covered by your Owner's Literature at the
vehicle's capacity weight and the tire sizes installed on the respec­
tive models as original equipment, or as a factory option.
