in. WARNING
• You should perform braking maneuvers for the purpose of
cleaning the brake system only if road condition s permit. Other
road u sers must not b e put at r isk - you may cau se an ac cident!
• Before d esc ending a steep gr ade , redu ce speed and shift tran s
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 brake s to get hot and diminish braking efficiency.
• Do not "ride the brakes " by re sting your foot on the pedal when
you do not intend to brake. Thi s may caus e the brakes to overheat ,
premature wear and increa sed stopping di stance.
• Under certain climatic and operating conditions such as
pas sing through water, driving in heavy rain or after washing the
vehicle, the effectiveness of the brake s can be reduced . In winter,
ice can accumulate on the brake pads , linings , disc s and drums .
Carefully apply brakes for a test. Brake s will dry and ice coatings
will be cleaned off after a few careful brake applications.
• Driving for an extended period of time on salt -cov ered roads
without using your brakes can al so affect braking efficiency. Clean
off accumulated salt coating from brake d iscs and pads with a few
careful brake applications.
• If you damage the front spoiler , or if you install a different
s poiler , be sure the air flow to the front brakes is 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 distance. Avoid driving the
vehicle and have it towed to the nearest authorized Audi dealer or
qualified wo rkshop. •
Brake booster
The brake booster adds e xtra brakin g pow er .
The brake booster works with vacuum pressure which is created only
w hen the en gine is ru nning =>& .
in. WARNING
• Never let the vehicle roll to a stop with the engine shut off .
• If the brake booster i s not working , for example when towing
your vehicle , or because the brake booster has somehow been
damaged , the brake pedal must be p ressed considerably harder to
make up for the lack of booster assistan ce.
Functioning of Anti-Lock Brake System
(ABS)
AB S prevents the wheels from locki ng up under braking.
T he ABS co ntribu tes effectively to vehicle co ntrol s ince it prevents t he
w hee ls from
locking when the b rakes are a pplied. This means t hat t he
veh icle rema ins steerable and is less likely to s kid .
W ith ABS you do not need to
pump the brake. Just hold the brake
pedal down .
However, do not expect the ABS to shorten braking distance u nder
oil
circums tances. When driving on grave l or on newly fa llen snow on top
of icy su rfaces, braking dis tance may be even longer, therefore, under
these c irc umstances, it is especially important that you dr ive slowly
and w it h great care .
How the ABS system works
An automatic check is made when a speed of about 12 mph (20 km/h)
is reached . Whe n this happens, a p umping noise can be hea rd. ._

Driving instructior,s
Driving with a trailer always requires e xtra care and
consideration.
To obtain the best possib le handling of ve hicle a nd trailer ,
please note the following :
- Do not tow a loaded trailer when your car itself is not
loaded.
- Be especia lly careful when pass ing other vehicles .
- Observe speed limi ts.
- Do not drive at the maximum pe rmissible speed.
Controls and equip
ment Safety first Vehicle operation
- Always apply brakes early.
- Mo
nitor the temperature gauge.
Weight distri but ion
T owing a loaded trailer with an empty car results in a highly unstable
distribution of we ight . If t his cannot be avoided , drive at very low
speeds only to avoid the risk of losing steering control.
A "balanced" rig is easier to operate and control. This means that the
tow veh icle shou ld be loaded to the extent poss ible and permissib le,
wh ile keeping the tra ile r as lig ht as poss ible unde r the ci rc u mstances.
Whe never possible, transfer some cargo to the luggage compart
me nt o f the tow vehicle while observing tongue load requirements
and vehicle loading considerations.
Speed
The higher the speed, the more d ifficult it becomes for the driver to
control the r ig . Do not dr ive at the maxim um permiss ible speed .
Reduce your speed eve n more if load, weather or w ind conditions are
unfavorable -particular ly when going downhill.
Reduce vehicle speed
immed iately if the tra ile r shows the slightest
sign of swaying.
Do not tr y to stop the s wayi ng by a ccele rating .
Observe speed lim its. In some areas, speeds for veh icles towing
trailers are lowe r than for regular veh icles .
Always apply brakes early. When driving downhi ll, shift into a lower
gear to use the engine brak ing effect to slow t he ve hicle . Use of the
brakes alone can cause them to overheat and fa il.
Coolant temperatur e
The coo lant temperature gauge=> page 10 must be observed care
fu lly. If the needle moves close to the upper end of the sca le, reduce
speed immediately and/or turn off the air conditioner.
If the coo lant temperature warning light in the instrument clus ter
starts flash ing
- F- , pull off the road, stop and let the engine idle for
about two m inutes to prevent hea t buil d-up.

Trailer towing tips
Important to know
Your vehicle handles differe ntly when tow ing a tra iler because of the
additiona l weight and different we ight distribution. Safety, perfor
man ce and economy w ill greatly depend on how ca refu lly yo u load
your trailer and operate your rig.
Be fore you actua lly tow your tra ile r, prac tice turning, stopp ing and
back ing u p in a n area away from traffic. Keep pract ic in g until you have
become completely familiar with the way your vehicle -trailer combi
nation behaves and responds .
Backing up is diff icult and requ ires pract ice. Backing up w ith a trailer
gene rally requires s teer ing a ction opposi te to th at when ba cki ng up
your vehicle witho ut a trailer.
Maintain a greate r d istance between your ve hicl e and the one in front
of yo u. You will need more room to stop . T o compensate fo r the
trai ler, you will need a larger than normal turning radius .
W hen p assing, remember that you c annot acceler ate as fast as yo u
normally wou ld because of the added load. Make sure yo u have
enoug h room to pass. After passi ng, allow plen ty of room fo r yo ur
tra iler before changing lanes again .
Avoid jerky starts, sharp turns or rapid lane changes .
[ i ] Tips
• Do not tow a trai ler d uring the brea k-in perio d of your vehicle. •
If you tow a tra iler, your Aud i may require more frequent mai nte
n an ce due to the ex tra load:::::>

5. Determine the combined weight of
luggage and cargo being loaded on the
v ehicle . That weight ma y not safel y
e xceed the available cargo and luggage
load capacity calculated in Step 4.
6 . If your v ehicl e will be towing a trailer,
load from your trailer will be transferred
to your vehicle. Consult this manual to determine how this redu ces the a vailable
cargo and luggage load capacity of your
vehicle.
Check the tire sidewall( =>
