rJ /. R ea r spoiler: system m alfun ct io n!
The rear spoiler may not have extended due to
a ma lf u nction. This could change the vehicle 's
driving characteristics at high speeds . Do not
exceed 85 mph (140 km/h). Drive to your au­
thorized Audi dealer immed iate ly to have the
malfunction corrected. The co lor of the indica­
tor light depends on the vehicle speed.
A WARNING
Dr iv ing at higher speeds w ithout the rear
spoiler dep loyed can impair handling char ­
acteristics, making the veh icle harde r to
cont ro l.
- Always make sure that the spoiler is de­
ployed when driving at speeds over
85 mph (140 km/h). If the rear spoiler
warning/ind icator light in the i nstr u­
ment cluster comes on, the rear spoiler
may not have dep loyed .
- Never drive at speeds higher than
85 mph (140 km/h) if the spoiler is not
deployed. Have the spoiler inspected as
soon as possible by an authorized A udi
dealer or qualif ied workshop.
- Always obey speed limits and other traf­
fic laws.
A WARNING
Improper operation of the rear spoiler can
cause crushing injuries.
- Always make sure that nobody, especially
children, is in the way when the rear
spoiler is deployed or retracted.

Braking
General information
What affects braking efficiency?
Operating condition s and dri ving h abit s
The brakes on today's automobiles are still
subject to wear, depending largely on operat­
ing condit ions and driving habits ¢.&, . On
vehicles that are either driven mostly in stop­
and-go c ity traff ic or are dr iven hard, the
brake pads should be checked by your author­
ized Audi dea ler more often th an specified in
the
Warran ty & Maintenan ce boo kle t. Failure
to have you r brake pads inspected can result
in reduced brake performance .
On steep slopes, you sho uld use the braking
effect o f the engine . This way, you prevent un ­
necessary wear on the b rake system. If you
must use your brakes, do not hold the brakes
down cont inuous ly. Pump the brakes at inter­
vals.
Mo istur e or road salt
U nder certain conditions , for example, when
driving through water or very heavy rain , or
even after washing your vehicle, the braking
effect can be reduced due to moisture (or in
free zing cond itions ice) on the brake pads. A
few carefu l brake applications should dry off
the brake pads or remove any ice coatings .
When you are driving at higher speeds with
the windshield w ipers on, the brake pads will

briefly touch the brake d iscs in regular inter ­
va ls so as to improve reaction time when brak­
ing on wet surfaces. You the driver wi ll not no­
tice anything.
The effectiveness of the brakes can be reduced
when the vehicle is driven on a salt-covered road and the brakes are not used . Here too,
you should clean off accumu lated salt coating
from brake discs and pads with a few careful
applicat ions of the brake¢,& .
Co rrosion
There may be a tendency for dirt to bui ld up
on the brake pads and corrosion to form on
the discs if the car is not dr iven regularly or
only for short trips with little use of the
brakes .
If the brakes are not used frequently, or if cor­ rosion has formed on the discs, it is advisable
to clean off the pads and discs by braking
firmly a few times from a moderately high
speed <=>,& .
Fa ul ts in th e brak e sys te m
If you should notice a sudden increase in
brake pedal travel, then one of the two brake
circu its may have failed¢,& .
Low b rak e flu id l evel
Malfunctions can occur in the brake system if
the brake fl uid level is too low. The brake fluid
level is monitored electronically .
Brake booster
The brake booster wor ks w ith vacuum pres ­
sure which is created only when the engine is running
c> ,& .
Brake lining wear st atu s
Brake lining wea r may be checked by visual in­
spection of the condition of the brake pads
through the openings in the whee l. If neces­
sary, the wheel may be removed for this in ­
spection ¢ page 269, Changing a wheel .
_& 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 ca use an accident!
- Before descend ing a steep grade, reduce
speed and sh ift transmission into a lower
gear o r lower dr iving range. Do not ride
the br akes or ho ld the pedal down too
long o r too often . T his 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 operat ing
conditions such as passing through wa­
ter, dr iving in heavy rain or after washing
the vehicle, the effectiveness of the brakes can be reduced . In winte r, ice can
accumu late on the bra ke pads, lin ings,
d iscs and drums. Carefully app ly bra kes
for a test. Brakes will dry and ice coa t­
ings wi ll be cleaned off after a few care­
fu l brake applicat ions.
- Driving for an extended period of t ime on
salt -covered roads without using your
brakes can a lso affect braking efficiency .
Clean off accum ulated salt coating from
brake discs and pads with a few careful
brake applications.
- If you damage the front spoiler, or if you
install a different spoiler, be sure the a ir
f low to the front brakes is not obstruct­
ed. Otherwise the brake system could
overheat reducing the effective ness of
the entire brake system.
- Failure of one brake circuit will impa ir
the braking capab ility result ing in an in­
creased stopping distance . Avoid driving
the vehicle and have it towed to the near­
est A udi dealer or qualified workshop .
- Never let the vehi cle roll to a s top with
the eng ine shut off.

-If the brake booster is not working, for
example when towing your vehicle, or
because the brake booster has somehow
been damaged, the brake pedal must be
pressed considerably harder to make up
for the lack of booster assistance.

Winter tires
When dr iving in the winter, your vehicle with
all-wheel drive has an advantage, even w it h
regular tires. In winter ro ad conditions it may
be advisable to mount winter tires (or all -sea ­
son tires) for improved driveability and brak­
ing: these tires must be mo unted on
all fou r
whee ls.

Tire chains
Where tire chains are mandatory on certain
roads, this norma lly also applies to veh icles
with all-wheel drive¢

chains.
Replacing wheels /tires
Vehicles with al l-wheel d rive must always
have tires of the same s ize. A lso avoid tires
with different tread depths . For detai ls see

The first 1,000 miles
(1,500 km) and
afterwards
New engine
The engine needs to be run-in during the first
1,000 miles (1,500 km).
For the fir st 600 miles (1,000
kilometers ):
.,. Do not use full throttle.
... Do not drive at engine speeds that are more
than 2/3 of the max imum permitted RPM.
... Avoid hig h engine speeds.
From 600 to 1,000 mile s (1 ,000 to
1,500 kilometers):
... Speeds can gradually be increased to the
max imum pe rm iss ible road or eng ine speed .
During and after break-in per iod
.,. Do not rev the engine up to high speeds
when it is cold. Th is app lies whether the
transm ission is i n N (Neutra l) or in gear.
After the break-in period
... Do not exceed maximum engine speed un­
der any circumstances.
.,. Upshift into the next hig her gear
before
reaching the red area at the end of the tach­
ometer scale
c:> page 11.
During the first few hours of driving, the en­
g ine's interna l friction is higher than later
when all the moving parts have been broken
in . How well this break- in p rocess is do ne de­
pends to a conside rable extent on the way the
ve hicl e is driven d uring the first 1,0 00 miles
(1, 500 k ilome ters).
0 Note
E xtremely high engi ne speeds are auto­
mat ica lly reduced. However, these rpm
lim its are progr amme d for an engine well
r u n- in, not a new engine .
{® For the sake of the environment
Do not drive with unnecessarily high en­
g ine speeds - upshifting ear ly saves fuel,
reduces no ise and protects the environ­
ment.
, New tires
If your vehicle is runni ng on new tires, drive
part icularly caref ul for the first 350 miles
(500 kilomete rs) afte r fitt ing .
A WARNING
New tires tend to be sl ippery and mus t al­
so be "broken -in" . Be s ure to remember
this dur ing the fi rst 350 mi les (500 kilo ­
meters) . Brake gently . Avoid fo llow ing
closely behind other vehicles or other sit­
uations that m ight require sudden, hard
braking .
New brake pads
Remember that new brake pads do not have a
full bra king effect dur ing the fi rst 250 m iles
(400 kilomete rs) afte r they a re insta lled .
New brake pads have to be "burnished in" be­
fo re t hey have optima l grab

During the break- in period, you should avoid
putting severe loads on the brakes. Severe
l oads include, for example, sudden hard brak­
i ng, in particular at very high speeds or, for
example, on mounta in passes .
A WARNING
New b rake pa ds don't have t he bes t stop­
pi ng power and mus t be "broke n-in " dur­
i ng the in iti al 1 00 to 150 mi les (150 to
20 0 kilometers) of no rma l city driving . You
can compensate for this by pressing the

206 Driving and en vir onm ent
Driving through water
on roads
Note the following to avoid vehicle damage
when driving thro ugh water, for example on
flooded roads:
- The wate r must not be any higher than the
bottom of t he vehicle body.
- Do not drive faster than wa lking speed.
A WARNING
After driving through wate r, mud, slush,
etc., the brakes may be slow to take effect
because of wet brake rotors and pads. Dry
the brakes first by braking carefully to re­
sto re the full braking effect.
@) Note
- Vehicle components such as the eng ine,
transmission, suspension or electr ical
system can be severely damaged by driv­ i ng th rough water.
- Always switc h off the Start-Stop-System
when driving through water~
page 80 .
(1) Tips
-Check the depth of the water before dr iv­
i ng th rough it.
- Do not stop the ve hicle, dr ive in reverse
or switch the engine off whe n driving
t hr ough water .
- Keep in mind that oncoming vehicles
may create waves that raise the water
level and make it too deep fo r you r vehi­
cl e to drive th rough safely.
- Avoid dr iving through salt water because
i t can cause corrosion.
Operate your vehicle
economically and
minimize pollution
General
Your personal style of driving will determine
the economy of your vehicle, as well as ex­
haust and noise levels.
Fuel economy, environmenta l impact, and
wear on your engine, brakes and tires largely
depend on three factors:
- your personal driving style
- oper ating conditions
- technical limitat ions
If you ant ic ipate what you need to do next and
drive economica lly, you can easily cut your
fuel consumpt ion by 10-15 percent . This sec­
t ion w ill give you some tips on how you can
help the env ironment and your pocketbook.
@ Tips
The consumption estimates as published
by ENVIRON MEN TAL PROTEC TION AG ENCY
( EP A) and Transpo rt Canada may no t corre­
spond to your actual consump tion on the
r oad, which will va ry depending upon vehi ­
cle load and speed, road and weather con ­
ditions, trip length, etc.
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they are ac­
celerating.
.,. Avoid unnecessary accelerating and braking.
Vehicles use the mos t fu el when they are ac­
ce le rat ing. If yo u ant icipate what is going to
happen next, you will need to brake less and,
t hu s, acce le rate less . Let the vehicle coast
whenever possible -for examp le when you see
t h at the next traff ic light is red.

Trailer towing Driving with a trailer
General information
Your Audi was designed primarily for passen­
ger transportation .
If you plan to tow a tra iler, p lease remember
that the addit ional load will affect durab ility,
economy and performance .
Trailer towing not on ly places more stress on
the vehicle, it also calls for more concentra­
tion from the driver.
F or this reason, a lways fo llow the operating
and driving instructions provided and use
common sense.
(D Note
If you are going to tow a trai ler, you must
ac tivate the trailer operation mode
c::> page 209, Operating instructions.
Technical requirements
Traile r hitch
Use a weig ht-carrying hitch conforming to the
gross trailer we ight. The hitch must be suita­
b le for your veh icle and trailer and must be
mounted securely on t he ve hicle's chassis at a
technically sound location . Use only a trail er
hi tch w ith a removab le ball moun t. A lways
check wi th t he tra ile r hi tch man ufa ctur er to
make sure that you are using the cor rect
h itch.
Do not us e a bumper hitch .
The hitch m ust be installed in such a way that
i t does not interfe re with the impac t-absorb­
i ng bumper syst em. No mod ificat ions should
b e made to the vehi cle e xhaus t and br ake sys­
tems . From t ime to time, check th at a ll hitc h
mo unt ing bo lts rem ain securely fas tened.
When you are not towing a trail er, remove the
tra ile r hi tch ball moun t. T h is prevents the
hi tch from causing damage sho uld your ve hi­
cle be str uck from behind~ .&.

brake system .
Safety chains
Always use safety chains be tween your ve hicle
and t he tra ile r.
Trailer lights
Trai ler lights must meet all reg ulations. Be
su re to c heck with your Audi dea ler for correct
wir ing, switches and relays .
Mirrors
If you a re unable to see the traffic behind you

Tire p res sure
When tow ing a trai le r, inflate the t ires of your
vehi cle to the co ld tire pressure listed under
"Full load" on the label located on the driver's
side B-pillar (visible when the door is open) .
Inflate trailer t ires to trai ler and tire manufac­
turers' specifications.
Lights
Chec k to make s ure both veh icle and trailer
lights are working properly.
Safety chains
Be sure tra iler safety cha ins are properly con­
nected from the trailer to the hitch on the ve­
h icle. Leave enough slack in the chains to per ­
mit turn ing corners . When you install safety
cha ins, make su re they wi ll not drag on the
road when yo u are driving.
The chains shou ld cross under the tra iler
tongue to prevent it from dropping in case of
separation from the hitch.
Adjusting the Audi drive select
Make sure the vehicle is on a level su rface be­

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 fo llow ing:
.,. Do not tow a loaded trailer when your car it­
self is not loaded.
.,. Be especially carefu l when passing other
veh icles.
.,. Observe speed lim its .
.,. Do not dr ive at the maximum permissible
speed.
.,. Always app ly brakes early .
.,. Monitor the temperatu re ga uge.
Weight distribut ion
T owing a loaded trailer with an empty car re­
su lts in a highly unstab le distribution of
we ight. If this cannot be avoided, drive at very
low speeds on ly to avoid t he risk of losing
steering con trol.
A "ba lanced " rig is easier to operate and con­
tro l. This means that the tow vehicle should
be loaded to the exten t possible and permissi­
ble, while keep ing the trai ler as light as possi­
ble under the c ircumstances . Whenever poss i­
ble, transfer some cargo to the luggage com ­
partment of the tow veh icle while observing
tong ue load requirements and vehicle load ing
considerations.
Speed
The higher the speed, the more difficu lt it be ­
comes for the driver to control the rig . Do not
drive at the maximum permissible speed. Re­
duce your speed even more if load, weather or
wind conditions are unfavorable -particularly
whe n going downhill.
Red uce veh icle speed
immediately if the trail­
er shows the slightest s ign of sway ing .
Do not
try to stop the swa ying b y accelerating .
Observe speed limits . In some a reas, speeds
for vehicles tow ing trai lers are lower than for
regular veh icles . .,.

Always apply brakes early. When driving
downhill, shift into a lower gear to use the en­
g ine braking effect to slow the vehicle . Use of
the brakes a lone can cause them to overheat
and fail.
Coolant temperature
The coolant temperature gauge ¢ page 11
must be observed carefully. The coo lant tem­
perature can increase if you drive on long in­
clines in a low gear at high engine speeds. Re­
duce your speed immediately if the LEDs in
the top part of the display turn on .
For more information about indicator lights,
refer to.

A WARNING
Anyone not properly restrained in a mov­
ing vehicle is at a much greater risk in an
accident . Never let anyone r ide in your car
who is not properly wearing the restra ints
provided by Aud i.
Trailer towing tips
Important to know
Your vehicle hand les different ly when towing
-
a trailer because of the additional weight and
d ifferent weight distribution . Safety, perform­
ance and economy w ill greatly depend on how
carefully you load your trailer and operate
your rig .
Before you actually tow your trailer, practice
turning, stopp ing and backing up in an area
away from traffic . Keep practicing until you
have become completely familiar with the way
your veh icle-trailer comb ination behaves and
responds .
Backing up is diff icult and requires practice .
Backing up with a tra iler genera lly requires
steer ing action opposite to that when backing
up your vehicle without a trailer.
Maintain a greater distance between your ve­
hicle and the one in front of you. You will need
more room to stop. To compensate for the
Trailer towing 211
trailer, you wi ll need a larger than normal
turning radius.
When passing, remember that you cannot ac­
ce lerate as fast as you norma lly would be­
cause of the added load. Make sure you have
enough room to pass. After passing, allow
plenty of room for your trailer before chang­
ing lanes again.
Avoid jerky starts, sharp turns or rapid lane
changes.
(0 Tips
- Do not tow a trailer during the break-in
period of your vehicle.
- If you tow a trailer, your Audi may re­
quire more frequent maintenance due to
the extra load¢
page 289.
Parking on a slope
Do not pork on a slope with a trailer . If it can­
not be avoided, do so only after doing the fol­
lowing:
When parking:
"' App ly the foot brake .
.,. Have someo ne p lace chocks under both the
veh icle 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.
.,. Select the P selector lever posit ion .
When restarting after parking:
.,. Apply the foot brake.
.,. Start the engine .
.,. Select the D/S se lector lever position .
.,. Release the parking brake and slowly pull
out and away from the wheel chocks.
.,. Stop and have someone retr ieve the wheel
chocks .

Cleaning and protect ion
General information
Regular core preserves vehicle value.
Any automobile is exposed to industrial
fumes , corrosive road salt, etc. A well cared
for Audi can look like new many years after
purchase . Regu lar and correct care w ill con­
tr ibute to maintaining the beauty and value of
your Aud i.
F u rth ermor e, good c are may be a conditi on

Your authorized Audi dealer has a variety of
dedic ated veh icle-car e products and can ad ­
vise which ones to use for cleaning the exter i­
or and interior of your vehicle.
Whether you use products recommended by
Aud i or other commercially available clean ing
agents, please make sure you apply them cor­
rectly .
A WARNING
-Cleaning agents may be poisonous. Keep
them out of the reach of children.
- Heed all caut ion labels.
- Always read directions on the container
before using any product. Follow the di­
rect ions carefu lly.
- Most chemical cleaners are concentrated
and have to be diluted .
- Use spot removing fluids only in well
ventilated areas.
- Do not use gasoline, kerosene, d iesel
fuel, nail polish remover or other volatile
fluids. They may be toxic, flammab le or
haza rdous in other ways. Do not wash,
wax or dry the vehicle with the ign it ion
on or the engine running.
- Do not clean the undersides of chassis,
fenders, wheel covers, e tc. w ithout pro­
tecting your hands and arms. You may c u t yourself on sharp -edged metal parts .
Cleaning and protec tion 213
- Moisture and ice on brakes may impair
brak ing effic iency¢
page 199, General
information.
Test the brakes carefully
each time you wash the vehicle.
@) For the sake of the environment
Select on ly environmentally friend ly clean­
i ng products . Leftover cleaning products
should not d isposed of in the household
waste.
Care of exterior
Washing
Frequent washing protects the vehicle .
The best protection against environmental i n­
fluences is
frequent washing and waxing . How
often t his is required depends on:
- How much the veh icle is used
- Where the veh icle is parked (garage, in the
open under trees, etc.)
- The seasonal and weather conditions
- Environmental infl uences
T he longer b ird droppings, insects, tree resin,
road and indus tria l gr ime, ta r, soot, road salt
and other materials remain on the vehicle
body, the more lasting their destructive ef­
fects wi ll be . High temperatures caused by ex­
posure to intense sun light intens ify the corro­
s ive effect, particularly when humid ity is high
as well.
Under certain circumstances,
weekl y washing
may be necessary. Under other cond itions, a
monthly washing and waxing may be ade­
quate .
After the winter, the underside of the vehicle
should be thoroughly washed, preferab ly in a
professional car wash .
