get into the pedal area and interfer e with peda l function . In ca se
of sudden braking or an accident, you would not be able to brake
or accelerate!
• Always make su re that noth ing can fall o r move into the
driver' s footwe ll. •
Floor mats on the driver side
Always use floor mats that can b e securely attach ed to
the floor mat fasteners and do not interfere with the fre e
movement of the pe dals.
- Make sure that the floor mats are properly secur ed and
ca nnot move and i nte rfere with t he peda ls=> &.

Corrosion
T he re may be a te ndency fo r d irt to build u p on the bra ke pads and
co rrosion to form on the d iscs if the car is not dr iven reg ularly o r only
for short trips with litt le use of the bra kes .
If the brakes a re not used freq uen tly, or if co rrosion has formed o n
the discs, it is advisable to clean off the pads and discs by braking
fir mly a few times from a mode rat ely h igh spee d~ & .
Faults in the brake system
If yo u sh ou ld noti ce a sudden increase in b rake peda l trave l, then one
of the two brake circu its may have failed~& .
Low brake fluid level
Ma lfunctions can occ ur in t he brake system if the brake fluid level is
t oo low. The bra ke f lu id level is moni tore d elec tron ically.
Brake lin ing wear status
Brake lin ing wear may be checked by v isua l inspect ion of the condi­
tion of the brake pads throu gh the open ings in the whee l.
If neces­
sary, the whe el may be removed fo r thi s insp ection~
page 320,
"Changing a w hee l".
& WARNING
• You should perform braking maneuvers for the purpose of
cleaning the brake system only if road conditions permit. Other
road users must not be put at risk - you may cau se an accident!
• Before descending a steep grade, reduce speed and shift trans­
mission into a lower gear or lower driving range. Do not ride the
brakes or hold the pedal down too long or too often . This could
cause the brakes to get hot and diminish braking efficiency.
• Do not "ride the brakes " by resting your foot on the pedal when
you do not intend to brake . This may cause the brakes to overheat ,
premature wear and increased stopping distance.
• Under certain climatic and operating condition s such as
passing through water , driving in heavy rain or after washing the
& WARNING (co ntinued )
vehicle, the effectiveness of the brakes can be reduced . In winter,
ice can ac cumulate on the brake pads, linings, dis cs and drums.
Carefully apply brakes for a test. Brakes will dry and ice coatings
will be cleaned off after a few careful brake appli cations.
• Driving for an extended period of time on salt-covered roads
without u sing your brakes can also affect braking efficiency . Clean
off accumulated salt coating from b rake discs and pads with a few
careful brake applic ations.
• If you damage the front spoiler, or if you install a different
spoiler, be sure the air flow to the front brakes i s not obstructed .
Otherwise the brake system could overheat reducing the effective­
ness of the entire brake system.
• Failure of one brake circuit will impair the braking capability
resulting in an increased stopping di stance. Avoid driving the
vehicle and have it towed to the nearest authorized Audi dealer or
qualified workshop.

make up for the lack of booster assistance. •

Trailer towing
Driving with a trailer
General information
Your Audi was designed primarily for passenger transpor ­
tation.
If yo u plan to tow a t rai ler, p lease rem emb er that the add itiona l load
wi ll affect durab ility, economy and performance.
T railer tow ing not on ly p laces mo re s tress on the vehicle, it a lso calls
for more concentrat ion from the driver.
For this reason, a lways follow the ope rating and dr iv ing instr uctions
prov ided and use common sense .
Technical requirements
Trailer hitch
Use a weight-carrying hitch conforming to the gross trailer weig ht.
Th e hitch mus t be suitable for yo ur vehicle a nd tra ile r and mus t be
mounted secure ly on the vehicle's chassis at a
technically sound l oca­
t ion. Use only a trailer hitch wi th a remov ab le b all m ount. Alw ays
check w ith the tra iler hitch manufacturer to make sure that you are
using t he cor re ct hi tch.
Do not use a bumper hitch.
The h itch must be installed in such a way t hat it does not interfere
w ith the impa ct-absorbing b umper system. No mod ifi cat ions sho uld
be made to the vehicle exhaust and brake systems. From time to
ti me, chec k tha t all hitc h mou ntin g bol ts rem ain secure ly f aste n ed.
When you a re not tow ing a tra iler, remove the tra iler hitch ba ll
mount. This prevents the hitc h from caus ing damage should yo ur
vehicle be struck from behind=> &.
Controls and equip­
ment Safety first Vehicle operation
Trailer brakes
If your trailer is eq
uipped with a braking system, check to be s ure that
i t confo rm s to all regula tions.
The tra iler hydraulic brake system must not be directly connected to
the vehicle's hydraulic brake system=>& .
Safety chains
Alw ays use safety chains be twee n your vehicle and the trai ler.
Trailer lights
Tr ailer l ights m ust meet all reg ulat io ns. Be su re to check with your
author ized Audi deale r for correct wir ing, switches, and re lays.
Mirrors
If you are unab le to see the traffic behind you us ing the regular
outside m irro rs, then you
must install extended m irro rs. It is impor­
tant that yo u
always have clear vision to the rear.
& WARNING
• If a trailer has electrical b rake s please note that these brakes
are not activated by the factory-fitted control unit -ri sk of acci­
dent!
• After removing the trailer hitch , do not store it in your vehicle.
In case of sudden braking, the hitch could fly fo rward and injure
you or your passengers. •

Trailer towing
"-------------------------------------------------
Trailer load distribution
Be sure the load in the trailer is held securely in pla ce to prevent it
from shifting forward, backward or s ideways.
Never allow a passenger to ride in a trailer => & in "Driving instruc­
tions" on
page 256.
Engine cooling system
Towing a trailer makes the eng ine work harde r. It is important that
the cooling system's performance is up to the additional load. Make
sure that the cooling system has enough fluid.
Tire pressure
When towing a trailer, inflate the tires of your vehicle to the cold tire
pressure listed under "Full load" on the label located either on the
dr iver's side B-pillar (visible when the door is open) or inside the fuel
filler flap . Inflate trailer tires to trailer and tire manufacturers' spec­
ifications.
Lights
The headl ight settings should be checked w ith the trailer attached
before driving off. Check to make sure both vehicle and trai ler lights
are working properly.
Safety chains
Be sure trailer safety cha ins are properly connected from the trailer
to the hitch on the vehicle. Leave enough s lack 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.
T he chains should cross under the trailer tongue to p revent it from
dropping in case of separation from the hitch.
Driving instruct!ons
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 veh icles .
- Observe speed limits.
- Do not drive at the maximum permissible speed.
- Always apply brakes early.
- Monitor the temperature gauge .
Weight distribution
Towing a loaded trailer w ith an empty car results in a highly unstable
distr ibution of weight. If this cannot be avoided, drive at very low
speeds only to avo id the r isk of losing steer ing control.
A "balanced" rig is easier to operate and control. Th is means that the
tow vehicle should be loaded to the extent possible and permissible,
wh ile keeping the trailer as light as possible under the c ircumstances.
Whenever possible, trans fer some cargo to the luggage compart ­
ment of the tow vehicle while observing tongue load requirements
and vehicle loading considerations.
Speed
Th e higher the speed, the more difficult it becomes for the driver to
control the r ig . Do not drive at the maximum permiss ible speed.
Reduce your speed even more if load, weather or wind conditions are
unfavorable -part icularly when go ing downhill.
Reduce vehicle speed
immediately i f the trailer shows the slightest
sign of swaying.
Do not try to stop the swaying by accelerating. _,

Observe speed limits. In some areas, speeds for vehicles towing
t railers are lowe r than for regular veh icles.
Always apply brakes early. When dr iv ing downh ill, sh ift in to a lower
gear to use the engine braking effect to slow the vehicle. Use of the
brakes alone can cause them to overheat and fail.
Coolant temperature
The coolant temperature gauge~ page 8 must be observed care­
fully. If the needle moves close to the upper end of the scale, reduce
speed immediately and/or turn off the air conditione r.
If the coolant temperature warning light in the instrument cluster
star ts flashing
-t- , pull off the road, stop and let the engine idle for
about two minutes to prevent heat bu ild-up.
& WARNING
Anyone not properly restrained in a moving vehicle is at a much
greater risk in an accident. Never let anyone ride in your car who is
not properly wearing the restraints provided by Audi. u
Trailer towing tips
Important to know
------------
Your vehicle handles differently when tow ing a tra iler because of the
additiona l weight and different weight distribution. Safety, perfor ­
mance and economy will greatly depend on how carefu lly you load
your trailer and operate your rig .
Before you actua lly tow your trailer, practice turning, stopping and
backing up in an area away from traffic. Keep pract icing until you have
become completely familiar with the way your vehicle-t railer combi­
nation behaves and responds.
Controls and equip­
ment Safety first Vehicle operation
Backing up
is d iff icult and requ ires practice . Backing up with a trailer
generally requires steering action opposite to that when backing up
your vehicle without a trailer.
Maintain a greater distance between your vehicle and the one in front
of you. You will need more room to stop . To compensate fo r the
trailer, you will need a larger than norma l turning radius.
When passing, remember that you cannot accelerate as fast as you
normally would because of the added load. Make sure you have
enough room to pass. After passing, allow plenty of room for you r
trailer before changing lanes again.
Avoid jerky starts, sharp turns or rapid lane changes .
[I) Tips
• Do not tow a trai ler during the break-in per iod of your vehicle.
• If you tow a tra iler, your Audi may requi re more frequent mainte­
nance due to the extra toad~
page 343. •
Parking on a slope
Do not park on a slope with a trailer. If it cannot be
avoided, do so only after doing the following:
When parking:
-Apply the foot brake.
- Have someone place chocks under both the vehicle and the
trailer wheels.
- With chocks in place, slowly release the brakes until the
wheel chocks absorb the load.
- Turn the wheels towards the curb.
- Apply the parking brake .
- Move the se lector lever to
