Faults in the bra ke sys tem
If you should notice a sudden increase in
b rake peda l travel, then one of the two brake
circuits may have failed¢.& .
Low brake flu id le vel
Malfunct ions can occur in the brake system if
the brake fluid level is too low . T he brake fluid
l eve l is moni to red electronica lly .
Bra ke lining w ear st atu s
Brake l ining wear may be checked by visual in­
spection of the condition of the brake pads
through the openings in the whee l. If neces­
sa ry, the wheel may be removed for this in ­
spection
¢page 236, Wheel change.
A WARNING
-You should perform braking maneuvers
for the purpose of cleaning the brake
system on ly if road conditions permit.
Other road users must not be put at risk -
you may cause an acc ident!
- Before descending a steep grade, reduce
speed and shift transmiss ion into a lower
gear or lower driving range . Do not ride
the brakes or hold the pedal down too long or too often. This cou ld cause the
brakes to get hot and dimin ish braking
efficiency.
- Do not "r ide the brakes" by resting your
foot on the pedal when yo u do not intend
to bra ke . This may cause the brakes to
overheat, premature wear and increased
stopping distance .
- Under certain climat ic and operating
condit ions such as passing through wa­
ter, driving in heavy rain or after washing
the vehicle, the effectiveness of the brakes can be reduced. In winter, ice can
accumulate on the brake pads, linings,
discs and drums . Carefully apply brakes
for a test . Brakes will dry and ice coat­
ings will be cleaned off after a few care­
ful brake applications.
- Driv ing for an extended period of time on
salt-covered roads w ithout us ing your
brakes can also affect braking efficiency . Clean off accumulated 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
flow to the front brakes is not obstruct­ ed. Otherwise the brake system could
overheat reducing the effectiveness 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 utho rized Audi dea le r or q ualified
wo rkshop.
Brake booster '
The brake booster adds extra broking power.
The brake booster works with vacuum pres­
sure which is created only when the eng ine is
run ning ¢.&_ .
_&. WARNING
-Never let the vehicle roll to a stop with
the engine shut off.
- I f the b rake booster is not working, for
examp le when towing yo ur vehicle, or
because the brake booster has somehow
been damaged, the brake pedal must be
pressed conside rably harder to make up
for the lack of booster assistance.
Functioning of Anti-Lock Brake System
(ABS)
ABS prevents the wheels from locking up un­ der broking.
.
The ABS contributes effectively to vehicle con­
trol since it prevents the whee ls from
locking
when the brakes are applied. This means that
the vehicle remains steerable and is less likely
to sk id .
With ABS you do not need to pump th e
brake. Ju st hold the b ra ke pedal down.

Driving and
environment
The first 1
1000
miles
(11500 km) and
afterwards
New engine
The engine needs to be run-in during the first
1,000 miles (1 ,500 km) .
For the first 600 mile s (1,000
kilometers ):
.,. Do not use full throttle.
.,. Do not d rive at engine speeds that are more
than 2/3 of the max imimum permitted
RPM .
From 600 to 1,000 miles (1 ,000 to
1,500 kilometers):
.. Speeds can gradually be increased to the
maximum pe rm iss ible road or eng ine speed .
During and after break-in per iod
.,. Do not rev the engine up to h igh speeds
when it is cold. This applies whether the
transmission is i n N (Neutra l) or in gear.
After the break- in peri od
.. Do not exceed maximum engine speed un­
der any circumstances .
.,. Upshift into the next higher gear
before
reaching the red area at the end of the tach­
ometer scale
¢ page 10.
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
i n. How well this break-in p rocess is done 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).
(D Note
Extremely high engine speeds are auto­
mat ically reduced. However, t hese RPM ­
lim its we re p rogrammed fo r an engi ne
we ll ru n- in, not a new engine .
Driving and environment 169
@) For the sake of the environment
Do not drive with unnecessarily high en­
g ine speeds -upshifting ear ly saves f uel,
reduces noise and protects the environ­
ment.
New tires
If your vehicle is running on new tires, drive
particularly caref ul for the first 300 miles
(500 kilomete rs) afte r fitt ing.
.&, WARNING
N ew tires tend to be sl ippery and mus t al­
so be "b roken -in" . Be sure to remember
this dur ing t he f irst 3 00 m iles (500 kilo­
meters) . Brake gently . Avoid fo llow ing
closely behind other vehicles or other sit­
uations that m ight require sudden, hard
b raking .
New brake pads
Remember that new brake pads do not have a
full brak ing effect dur ing the first 250 m iles
(400 kilomete rs) afte r they a re install ed.
New brake pads have to be "burnished in" be­
fore they have optima l grab¢ .&. .
D uring the brea k-in period, yo u should avo id
putting severe loads on the brakes. Severe
l oads include , for example, sudden hard brak­
i ng, in particular at very h igh speeds or, for
example, on mounta in passes .
.&, WARNING
Until they develop the maximum "bite" for
bes t stopping power, the s urfaces on new
brake p ads re quir e some "breaking -in" dur­
ing the initia l 100 to 150 miles (15 0 to
200 kilometers) of no rma l city driving . You
can compensate for this by pressing the b rake peda l more f irm ly. This applies
whenever new pads are installed.

170 Driving and en vironm ent
Driving through water on roads
Note the following to avoid vehicle damage
when dr iv ing t hrough water, for example on
flooded roads:
- The water must not be any higher than the
bottom of the vehicle body.
- Do not drive faster than walking speed.
A WARNING
After d riving through wate r, mud, slush,
etc., the brakes may be slow to take effect
because o f wet brake ro tors and pads. Dry
the brakes f irst by bra king carefully to re ­
store the full braking effect .
({D Note
Vehicle components such as the engine,
t ransmiss ion, suspens ion or elect rical sys­
tem can be severely damaged by driving
through wate r.
(D Tips
-Che ck the depth of the water before dr iv­
i ng through it.
- Do no t stop the veh icle, dr ive in reverse
or switch the engine off when d riving
th rough water.
- Keep in mind that oncoming vehicles
may c reate waves that raise the wate r
l evel and make it too deep for yo ur vehi­
cle to drive th rough safely .
- Avoid driving thro ugh salt water because
i t can ca use corrosion.
Catalytic converter
-
It is very important that your emission con­
trol system (catalytic converter) is function­
ing properly to ensure that your vehicle is run­
ning in an environmentally sound manner .
"' Always use lead-free gasoline¢ page 189,
Fuel supply.
"' Never run the tank down a ll the way to
empty .
"' Never put too much motor oil in your en­
gine ¢
page 200, ~ Adding engine oil .
"' Never try to push -or tow-start you r vehicle .
T he ca talytic converter is an efficient "clean­
u p" dev ice bui lt into the exhaust system of
the vehicle . The cata lytic conve rter bu rns
many of the pollutants in the ex ha u st gas be ­
fore they are re leased into the atmosphere.
T he exclusive use of unleaded f uel is c rit ically
important for the life o f the catalyt ic convert ­
er and prope r function ing of the engine .
A WARNING
-Do not park or operate the vehicle in
areas where the hot exhaust system may
come in contact with dry grass, brush,
fue l spill or other material wh ich can
cause a fire .
- Do not app ly additional undercoating or
rustp roofing on or near the exhaust
manifold, exhaust pipes, catalytic con­
verter or heat shields. Dur ing driv ing, the
substance used fo r under coating could
overhe at and cause a fire.
((0 Note
-Be aware that just one tank filling with
leaded fuel w ill alr eady ser iously de­
grade the performance of the catalytic
converte r.
- Do not exceed t he cor rect engine oil level
¢page 200.
-Do not dr ive until t he fuel tank becomes
completely empty. The engine cou ld mis­
fire. Unburned fuel could also get in to
the exhaust system and th is co uld cause
t he catalytic converter to overheat .
- Do not tu rn off the igni tion while the ve­
hicle is mov ing.
- Do not continue to ope rate your veh icle
under these conditions, as ot herwise fuel
can reach the catalytic converter. This
cou ld resu lt in overheating of the con­
verter, requir ing its replacement.
- To assu re efficient operation of the Emis -
sion Control System : ..,.

-Have your vehicle maintained properly
and in accordance with the service rec­
ommendations in your Warranty
&
Maintenance booklet.
- Lack of proper maintenance as well as
improper use of the vehicle will impair
the function of the emission control
system and could lead to damage.
@ For the sake of the environment
Even when the Emission Control System is
operating properly, the exhaust gas can
have a sulfur-like exhaust gas smell under
some operating states. This depends on
the sulfur content of the fuel being used .
Using a different brand of fuel may help,
or filling the tank w ith lead-free super
grade gasoline.
Diesel particulate filter
Ap plies to vehicles: with diesel partic ul ate filter
The diesel particulate filter filters nearly al l of
the soot part icles out of the exhaust. The fi l­
ter cleans itse lf automatically under normal
driving conditions . If the fi lter cannot clean it­
self (for example, because you are only driving
short distances), the filter becomes clogged
with soot and the
II symbol for the diesel
particulate filter illuminates
c> page 22.
A WARNING
- Do not park your vehicle over flammable
materials such as grass or leaves because
the high temperature of the diesel par­
t icu late filter could start a fire .
- Do not apply an underbody protectant in
the exhaust system a rea or a fire could
start.
(D Tip s
-When the diesel particulate filter be­
comes saturated, the engine speed in­
creases to approximate ly 1,500 rpm
while the vehicle is in motion to init iate
the cleaning of the diesel particulate fil­
ter a utomatically without the warning
l amp lighting up . If the warning lamp
Dri vin g and en vironm ent 171
Ill sti ll appears, you shou ld drive to a
qualified workshop .
Avoid damaging the
vehicle
When you are driving on poor roads, or over
curbs, steep ramps, etc., make certain that
low -lying parts such as spo ilers and exhaust
system parts do not bottom out and get dam­
aged.
This is espec ially true for veh icles with low­
slung chassis (sports chassis) and fully loaded
vehicles.
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, env ironmenta l impact, and
wear on your eng ine, brakes and tires largely
depend on three facto rs:
- your personal driving style
- operating conditions
- technical limitations
If you ant ic ipate wha t you need to do next and
drive economically, you can easily cut your
fuel consumptio n by 10-15 percent . This sec­
tion wi ll give you some tips on how you can
help the env ironment and your pocketbook.
(D Tips
The consumption estimates as published
by ENVIRONMENTAL PROTECTION AGENCY
(EPA) and Transport Canada may not corre­
spond to your actual consumption on the road, which will vary depending upon vehi­
cle load and speed, road and weather con­
dit ions, trip length, etc.

174 Trailer towing
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 durability,
economy and performance.
T railer towing not on ly places more stress on
the vehicle, it also calls for more concentra­
tion from the driver.
F or this reasons, always follow the operating
and drivi ng in str uctions provided and use
common sense.
Technical requirements
Traile r hitch
Use a weight-carrying hitch conforming to the
gross trailer weight. The hitch must be suita­
b le for your veh icle and trailer and must be
mounted securely on the ve hicle's chassis at a
technically sound location. Use only a trailer
h itch with removable ba ll mount. Always
check with the tr ailer hitch manufac turer to
make sure tha t you are using t he cor rect
hitch.
Do not us e a bumper hitch .
The hitch must be installed in such a way that
it does not interfere with the impact-absorb­
ing bumper syst em. No modifications should
be made to the vehi cle exhaust and brake sys ­
tems. From time to time, check th at a ll hitch
mo unt ing bo lts remain securely fastened.
When you are not towing a trailer, remove the
tra iler hitch ball mount. This prevents the
h itch from causing damage sho uld your ve hi­
cle be str uck from behind
¢ A .
Tire pressure
When tow ing a traile r, inflate the t ires of your
ve hicle to the co ld tire pressure listed under
"Full load"on the stick er on the rig ht doo r- jamb. Inflate trailer tires to trailer and tire
manufacturers' specifications.
Lights
T he headlight set tings sho uld be checked with
t h e trai le r attached before d riving o ff. Have
the headlights adjusted as necessary so tha t
yo u can see t he road ahead b ut not blind on­
coming traffic.
Check to make sure bo th ve hicle and tr ailer
lights are wo rk ing properly .
Engine cooling system
T owing a t railer makes the engine work hard­
er.
It i s impo rtant that the cooling system's
performance stands up to the additional
stra in. Make sure tha t the cooling sys tem has
enough fluid.
Trailer brakes
If your trailer is equipped with a brak ing sys­
tem, c heck to be sure t hat it conforms to all
regula tions.
The trailer hyd raulic brake system must not be
directly connected to the vehicle's hydraulic
brake system.
Safety ch ains
Be sure trailer safety chains are properly con­
nected from the trailer to the hitch on the ve­
hicle. Leave enough slack in the cha ins to per­
mit turning co rne rs. When yo u in stall safety
c h ains, ma ke sure they will not drag on the
r oad when you a re driving.
The chains should cross under the t railer
tong ue to prevent it from dropping in case of
separation from the h itch.
Trailer lights
Trai ler lights must meet all regulations. Be
sure to check w ith your authorized Audi dealer
for correct w ir in g, sw itches and re lays .
Mir rors
If you are unable to see the traffic behind you
us ing the regular outside mirrors, then you

must install extended mirrors. I t is important
that you
always have clear vision to the rear.
A WARNING -
After removing the tra ile r hitch, do not
store it in your vehicle. In case of s udden
braking , the hitch could fly forward and in­
jure you or your passengers .
Operating instructions
Maximum trailer weight
A trailer for your ve hicle is limited to a typica l
class 1 o r class 2 trailer.
Trailer l oad di stribut ion
Be s ure the load in the trai ler is he ld sec urely
in place to guard aga inst shift ing, be it for­

Tire pressure
When tow ing a tra ile r, i nflate the ti res of yo ur
ve hicl e to the co ld tire pressure listed u nder
"Full load" on the sticker on the r igh t door ­
jamb . Inflate trai ler ti res to trai ler and tire
manufacturers' specifications.

Trailer towin g 175
Driving instructions
Driving with a trailer always requires extra
care and consideration .
To obtain the best possible handli ng of vehicle
and trailer, please note the fo llow ing:
... Do not tow a loaded t railer w hen you r ca r it­
self is not loaded .
... Be especially caref ul when pass ing other ve­
hicles .
... Obse rve speed lim its .
... Do not dr ive at the maximum permissib le
speed.
... Always app ly brakes e arly .
... Mon itor the tempe rature g auge.
Weight distribution
Towing a loaded t railer w ith an em pty car re­
su lts in a highly unstab le distrib ution of
weig ht. If th is cannot be avoided d rive at very
l ow speed s on ly t o a void t he ri sk of losi ng
stee ring cont rol.
A "ba lanced " rig is easier to operate and con­
tr ol. Th is means t hat the tow vehicle should
b e lo ade d to t he e xten t possible and per miss i­
ble while keep ing t he tr ailer a s light as possi ­
ble under the c ircu mstances . Wheneve r poss i­
ble, transfe r some ca rgo to the lugga ge com­
partment of the tow vehicle w hile obse rv in g
tong ue load requ irements and vehicle load ing
consideratio ns.
Speed
The higher the speed, the mo re di fficu lt it be ­
comes for the driver to contro l the rig . Do not
drive at the maximum permissib le speed. Re ­
duce your speed even more under unfavo rable
load, weather or wind conditions - partic ularly
whe n going downhill .
Red uce veh icle speed
immediately if the trail­
er shows t he slig htest s ign of sway ing.
Do not
try to stop the swaying by accelerating .
Observe speed limits . In some a reas speeds
f or vehicles tow ing tra ile rs a re lower than for
r egular veh icles .
•
•

176 Trailer towing
Always app ly bra kes early . When driving
downhill, shift into lower gear to use the en­
g ine braking effect to slow down the vehicle.
Use of the brakes alone can cause them to
overheat and fail.
Coolant temperature
The coolant temperature gauge ¢ page 11
must be observed carefully. If the needle
moves close to the upper end of the scale, re­
duce speed immed iate ly and/or switch
off the
a ir cond itioner.
If the coolant temperature warning light in
the instrument cluster starts flashing
J_, pull
off the road, stop and let the engine idle for
about two minutes to prevent heat build-up.
A WARNING
Anyone not properly restrained in a mov­
ing veh icle is at a much greater risk in an
accident . Never let anyone r ide in your car
who is not prope rly wear ing the restra ints
provided by Aud i.
Trailer towing tips
Important to know
Your veh icle handles different ly when towing
-
a trailer because of the addit io nal weight and
weight distribution . Safety, performance and
economy w ill greatly depend on how carefu lly
you load your trai ler and ope rate your rig .
Before you actually tow your trailer, practice
turn ing, stopp ing and back ing up in an area
away from traffic. Keep practicing until you have comp letely become fam iliar w ith the way
your ve hicle-trai ler comb ination behaves and
responds .
Backing up is d iff icu lt and requires practice .
Backing up with a tra ile r genera lly requ ires
steer ing act ion opposite of tha t when backing
up your veh icle without a trailer .
Ma intain a g reater distance between your ve­
h icle and the one in fro nt of you. You will need
mo re room to stop. To compensate for the trailer, yo
u will need a
larger than normal turning radius.
When passing, remember that you cannot ac ­
ce le rate as fas t as you no rma lly would be­
cause of the added load. Make sure yo u have
enough room to pass . After passing, a llow
plenty of room for your trailer before chang ­
ing lanes again.
Avoid jerky starts , sharp turns or rapid lane
changes.
(D Tips
- Do not tow a trailer during the break -in
period of your vehicle.
- If you tow a trailer, yo ur Audi may re­
quire more frequent maintenance due to
the extra load ¢
page 2 59.
Parking on a slope
Do not park with a trailer on a slope . If it can­
not be avoided, do so only after doing the fol­
lowing:
When parking:
.,. App ly the foot brake.
.. Have someone p lace cho cks under both the
veh icle and the trailer wheels.
.. With chocks in place, slowly release the
brakes unti l wheel b locks absorb th e load.
.. Turn the whee ls towards the cu rb.
.. App ly the parking brake.
.. Place an automat ic transm ission in
P, re­
spectively a manual transmission in first or
reverse gear .
When restarting after p ark ing:
.. Start the engine.
.. Shift transm ission into gear .
.. Release the parking brake and slowly pull
out and away from the wheel blocks.
.,. Stop and have someone retr ieve the wheel
b locks .

c::> page 163 , General
information.
Test the brakes carefully
each time you wash the vehicle .
@ For the sake of the environment
Select only environ mentally friendly clean­
i ng products. Leftover cleaning products
should not d isposed of in the househo ld
waste .
Care of exterior
Washing
Frequent washing protects the vehicle .
The best protection against environmental in ­
fluences is
frequent washing and waxing .
How often this is required depends on:
- How much the vehicle is used
- Where the veh icle is parked (garage, in the
open under trees, etc.)
- The seasona l and weather conditions
- Environmental i nfl uences
The longer b ird droppings, insects, tree resin,
r oad and industrial gr ime, tar, soot, road salt
and other mater ials remain on the veh icle
body, the mo re lasting their destructive ef­
fects w ill be .
High temperatures , as from expos ure to in­
tense sun light, intensify the corrosive effect
part icularly when hum idity is high as well.
Under certa in circumstances,
we ekly washing
may be necessary. Unde r other cond itions, a
monthly washing and waxing may be ade­
quate.
After the winter, the unders ide of the vehicle
should be thoroughly washed, preferably in a professional car wash .
A WARNING
Always read and heed all WARNINGS and
other info rma tion
c::> page 178 .

182 Cleaning and protection
• Wipe the windows dry with a clean piece of
cloth or kitchen paper towel.
The best way to remove snow from w indows
and mir rors is to use a brush. Use a non -abra­
sive
pla stic ice scraper -better still, a spray
deicer -to remove
ic e from windows and mir­
rors.
The windows must not be cleaned with insect remover or wax since these can interfere with
the function of the windshield wiper blades (chatter).
O il, grease or silicone residue can be removed
with
glass cle aner or silicone remo ver. How­
ever, wax residue req uires the use of a specia l­
ly form ulated solvent. P lease contact your au­
thor ized Audi dealer for adv ice on safe prod­
ucts for wax removal.
Windows sho uld a lso be cleaned on the inside
at regular interva ls.
Never dry windows with the same chamois
that you use to dry painted s urfaces. Wax resi­
due on the chamois can impair vision thro ugh
the windows.
A WARNING
- The windshie ld m ust not be treated with
water-repellent materials. They can i n­
c rease glare under poor visib ility condi­
t ions such as wetness, darkness, o r whe n
the sun is low on the hori zon. In addi­
t io n, they ca n cause the wi ndshield wip ­
ers to chatter .
- Always read and heed all WARN INGS and
othe r inform ation
Qpage 178.
0 Note
- Never use warm or hot water to remove
s now and ice from windows a nd mirrors.
This cou ld cause the g lass to c ra ck .
- To prevent damage to the wi res of the
r ear defogger, do not place any adhesive
sticke rs o n the inside of t he rear w indow
ove r the wires.
- To he lp prevent d irt from s cratch ing the
window, always scrape i n a forwar d di- rec
tion -pushing the sc raper away from
you -never bac k and fort h.
Steel wheels
Applies to vehicles: with steel wheels (e .g. if refitted with
winter tires)
The wheels also have to be cleaned.
• Always include the hub caps and wheel rims
when wash ing your vehicle to remove road
dirt, sa lt sprays and brake dust .
If necessary, use a commercial whee l cleaner
to remove accumulated brake dust.
The wheel rims are easier to keep clean i f they
are regularly coated with liq uid wax.
Paint scra tches shou ld be touched up as soon
as possib le to prevent corrosion

Cast (light) alloy wheels
Applies to vehicles : with Cast alloy wheels
-
Cast (light) alloy wheels require special care.
• Wash the w heels with a sponge or hose
brush every other week .
• For deep cleaning afterwards, use on ly a
ded icated acid-free cast alloy wheel cleaner.
• Rub a coat of
liquid wa x onto the rims every
three month. Be sure to reach and treat all
parts of the rim .
To preserve the decorative appearance of the cast alloy w heels, some special care is neces ­
sary. In addition to road dirt and salt, brake dust is also co rrosive . If left on fo r too long,
brake d ust can cause pitting.
U se only spec ial
acid -free cleaners formulated
fo r alloy r ims . Safe products are ava ilab le at ..,_

your authorized Audi dealer. Never leave the cleaner on the rims longer than specified on
the label. If not rinsed
off promptly, the acid
contained in some cleaners can attack the
threads on the wheel bolts.
Never use abrasive or meta l polishing clean­
ing agents.
