On slopes, activate the parking brake first and
then move the selector lever to the P posit ion.
Aut omatic transm issio n
This prevents too much stress from being placed
on the locking mechanism .
A WARNING ,-
-The vehicle can also roll when the engine is
stopped.
- Unintended vehicle movement can cause se­
rio us injury.
- Never leave your vehicle with the engine
running while in gear . If you must leave your
veh icle when the engine is running, activate
the park ing brake and move the selector lev­
er to P .
- Power is still transmitted to the wheels
when the engine is runn ing at idle . To pre­
vent the vehicle from "creep ing", you must
keep your foot on the brake when the eng ine
is running and the se lector lever is in D/S or
R or "tiptronic" mode is selected.
- Do not press the accelerator pedal when
changing the se lector lever position while
the vehicle is stationary and the eng ine is
r u nning .
- Never sh ift into R or P while driving ,
- Before driving down a steep s lope, reduce
your speed and sh ift into a lower gear with
" t ipt ronic ".
- Do not ride the brakes or press the brake pedal too ofte n or too long whe n driving
down a hi ll. Constant brak ing causes the
b rakes to overhea t and substantially re­
duces braking performance, increases brak­ ing distance or causes comp lete fai lure of
the brake system.
- To prevent the vehicle from ro lling back
when stopping on inclines, always ho ld it in
p lace with the brake pedal or parking brake.
- Never hold the vehicle on an incline with a
slipping clutch. The clutch opens automati­
cally when it becomes too hot from the
overload. An ind icator lamp@] illuminates
and a driver message appears¢

Braking
What affects broking efficiency?
New brake pads
During the first 250 miles (400 km), new brake
pads do not possess their full braking effect, they
have to be "broken in" first¢,&. . You can com­
pensate for this slightly reduced braking power
by pushing harder on the brake pedal. Avoid
heavy braking loads during the break-in period.
Operating conditions and driving habits
The brakes on today's automobiles are still sub­
ject to wear, depending largely on operating con­
ditions and driving habits~,&. . On vehicles that
are either driven most ly in stop-and -go city traf­
fic or are driven hard, the brake pads should be
checked by your authorized Audi dealer more of­
ten than specified in the
Warranty & Mainte­
nance booklet .
Failure to have your brake pads
i nspected can result in reduced brake perform­
ance .
On steep slopes, you should use the braking ef­
fect of the engine . This way, you prevent unnec­
essary wear on the brake system. If you must use
your brakes, do not hold the brakes down contin­
uously. Pump the brakes at intervals.

Operating noise
Noises may occur when braking depending on the
speed, braking force and outside conditions such
as temperature and humidity.
Effect of water and road salt
In certain situat ions, for example after driving
through water, in heavy ra in, after overn ight con­
densat ion or after washing your car, the braking
effect can be reduced by moisture or ice on the
brake rotors and brake pads. The brakes must be
dried first with a few carefu l brake applications.
At higher speeds and with the w indshie ld w ipers
turned on, the brake pads press against the brake
rotors for a short amount of time. This occurs at
regular intervals without the driver noticing and
provides for better brake response time under
wet conditions.
The effectiveness of the brakes can be reduced
when the vehicle is driven on a salt-covered road
and the brakes are not used. Likewise, you clean
off accumulated salt coating from brake discs
and pads with a few cautious applications of the
brake ¢.& .
Corrosion
There may be a tendency for dirt to build up on
the brake pads and corros ion to form on the discs
if the car is not driven regularly or only for short
tr ips with little use of the brakes.
If the brakes are not used frequently, or if corro­
sion has formed on the discs, it is advisab le to
clean off the pads and discs by braking firmly a
few t imes from a moderately high speed¢.&.
Faults in the brake system
If you should notice a sudden increase in brake
pedal trave l, then one of the two brake circuits
may have failed
c:> .& .
Low brake fluid level
Malfunctions can occur in the brake system if the
brake fluid level is too low. The brake fluid leve l is
~ monitored e lectronically.

Brake lining wear status
Brake lining wear may be checked by visual in­
spect ion of the condition of the brake pads
through the openings in the wheel. If necessary,
the wheel may be removed for this inspection
c:> page 226, Replacing wheels.
_8 WARNING "'---
-New brake pads don't have the best stop­
pin g power and must be "broken-in" during
the initial 250 miles (400 kilometers). You
can compensate for this by press ing the
brake pedal more firmly. This also applies
later when new pads are installed.
-
- You shou ld perform braking maneuvers for
the purpose of cleaning the brake system
only if road conditions permit. Other road
users must not be put at r isk -you may
cause an acciden t!
- Before descending a steep grade, reduce
speed and shift transmission 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 over­
heat, premature wear and increased stop­
p in g distance.
- Under certain cl imatic and operat ing condi­
tions such as passing through water, dr iv ing
in heavy rain or after washing the vehicle,
the effectiveness of the brakes can be re­
duced. In winter, ice can accumulate on the
b rak e pads, linings, discs and drums. Care­
fully apply brakes for a test. Brakes will dry
and ice coatings will be cleaned off after a
few careful brake applications.
- Driving for an extended period of time on
salt -covered roads wi thout using your
brakes can a lso affect braking efficiency .

Driving and th e environment
(D Tips
- Check the depth of the water before driving
through it.
- Do not stop the veh icle, drive in reverse or
switch the engine
off when driving through
water.
- Keep in mind that oncoming vehicles may
create waves that raise the water level and
make it too deep for your vehicle to dr ive
through safely.
- Avoid driving through sa lt water because it
can cause corrosion.
Catalytic converter
It is very important that your emission control
system (catalytic converter) is functioning prop­ erly to ensure that your vehicle is running in an
environmentally sound manner .
~ Always use lead-free gasoline¢ page 186,
Fuel supply .
~ Never run the tank down a ll the way to empty .
~ Never put too much motor oil in your engine
¢ page 195, 9::?1 Adding engine oil .
~ Never try to push- or tow -start your veh icle.
The cata lytic conve rter is an eff icient "clean-up"
dev ice bu ilt into the exhaust system of the vehi­
cle. The cataly tic converter burns many of the
pollutants in the exhaust gas before they are re ­
leased into the atmosphere.
The ex clusive use of u nleaded fuel is critically im­
por tant for the life of the catalyt ic converte r and
p roper functioning o f the engine.
A WARNING ,..___ -
- The temperature of the exhaust system is
high, both when driving and after stopping
the engine.
- Never touch the exha ust tail pipes once they
have become hot. This could result in burns.
- Do not park o r operate the vehicle in areas
whe re the hot exhaust system may come in
contact with dry grass, brush, fue l spill or
other mater ial which can cause a fire.
- Do not apply additional undercoating or
rustproofing on or near the exha ust man i-
178
fold, exha ust pipes, catalytic converter or
heat shields. During driv ing, the substance
used for undercoat ing could overheat and
cause a f ire.
Cl) Note
- Be aware that just one tank fill ing with
le ad·
ed
fue l w ill already ser iously degrade the
performance of the catalytic converter.
- Do not exceed the correct engine oil level
¢page 195.
-Do not drive until the fue l tank becomes
completely empty. The engine co uld m isfire.
Unburned fuel could also get into the ex­
haust system and this could cause the cata­
lyt ic converter to overheat.
- Do not turn
off the ignition while the vehicle
is moving .
- Do not continue to operate your veh icle un­
der these conditions, as otherwise fuel can
reach the catalytic converter . This could re­
sult in overheating of the conve rter, requ ir­
ing its replacement.
- T o assure efficient operation of the Emission
Cont ro l System:
- Have your vehicle maintained properly and
in accordance with the se rvice recommen­
dations in yo ur Warranty
& Maintenance
booklet.
- Lack of proper maintenance as we ll as im­
proper 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 Emiss ion C ontrol System is op­
e rat ing proper ly, the exhaust gas can have a
sulfur-like exhaust gas sme ll under some op­
erat ing states. This depends on the sulfur
content of the fuel being used. Us ing a d iffe r­
ent brand of fue l may he lp, or fi llin g the tank
wi th lead-free s uper grade gaso line.
Shutting down vehicle
If you would like you r vehicle to remai n inope ra­
tive for a longer period of time, con tact an Audi
o r other spec ia liz ed dealer. They can adv ise you .,.

Trailer mode Driving with a trailer
General information
Your Audi was designed primarily for passenger
transportation.
If you plan to tow a tra iler, p lease remember that
the additiona l load will affect durability, econo­
my and performance .
T railer towing not on ly places more stress on the
vehicle, it also calls for more concentrat ion from
the driver .
F or this reason, a lways fo llow the operating and
d riving instructions 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 suitable
for your vehicle and trailer and must be mounted
securely on the veh icle 's chassis at a technically
sound
location . Use on ly a tra iler hitc h with a re­
movable ba ll mou nt. Always chec k w ith the t ra il­
e r hitch m anu fac tur er to make sure that you a re
using the co rrec t hitch.
Do not use a bumper hitch .
The hitch must be installed in such a way that it
does not in terfere with the impact-absorbi ng
bumper system. No mod ificat ions should b e
mad e to the vehicle exhaust and brake systems .
Fr om time to t ime, c hec k t hat a ll h itch mou nti ng
bo lts remain sec urely fastened .
When you are no t tow ing a trailer,
remove the
trai ler hitch ball mount . Th is prevents the hitc h
fr om caus ing damage should you r vehicle be
s truck from behind¢,&. .
Trailer brakes
If yo ur tra iler is equipped w it h a braking system,
check to be s ure that it conforms to all regu la­
tions.
Trailer mode
T he trailer hyd raulic brake system must not be di ­
rect ly connected to the ve hicle's hydraulic b rake
system ¢.&. .
Safety chains
Alw ays use s afety ch ains be tween your ve hicle
and t he tra ile r.
Trailer lights
Tra ile r li ghts must meet all regulations. Be sure
to check w it h your author ized Audi deal er for cor­
r e ct w iring, sw itches, and relays.
Mirrors
If you are unable to see the traffic behind you us­
i ng the regular o uts ide mirrors, then you
must in ­
sta ll extended mirrors .
It is importa nt that you
always have clea r vision to the rea r.
_&. WARNING
- I f a trai ler has elec trical brake s please note
th at these b ra kes are not acti va ted by the
factory -fitted contro l unit -ris k of acci dent!
- After removing the t railer hi tch, do n ot store
it in your vehicle . In case o f su dden braking,
the hi tch could fly forward and injure you or
your passe ngers.
Operating instructions
Maximum traile r weight
A trai ler for you r vehicle is limited to a typical
class 1 or class 2 trailer.
Trailer load distribution
B e sure the load in the t ra iler i s held secure ly in
pla ce to prevent it from sh ifting forw ard , back ­
war d or sideways .
Never allow a passenger to ride in a trailer¢.&.
in Driving in struc tion s on page 182.
Engine cooling system
Towing a trailer makes the engine work harder . It
is important that the cooling system's pe rform­
ance is up to the additional load . Ma ke s ure that
t h e coo ling system has enoug h fluid.

Trailer mode
Tire pressure
When tow ing a trailer, inflate the tires of your ve­
hicle to the cold 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 tires to trailer and tire manufacturers'
specifications.
Lights
The headlight settings should be checked with
the trailer attached before driving off . Check to
make sure both vehicle and trailer lights are
working properly.
Safety chains
Be su re trailer safety chains are properly connect­
ed from the trailer to the hitch on the vehicle.
Leave enough slack in the chains to permit turn­
ing corners. When you install safety chains, make
sure they will not drag on the road when you are
driving.
The chains shou ld cross under the trai ler 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 trai ler, please note the following:
.. Do not tow a loaded trailer when your car itself
is not loaded .
.. Be especia lly careful when passing other
vehicles.
.. Observe speed limits.
.. Do not drive at the maximum permissible
speed .
.. Always apply brakes early.
.. Monitor the temperature gauge.
Weight distribution
Towing a loaded trai ler with an empty car results
in a highly unstable distribution of weight. If this
cannot be avoided, drive at very low speeds only
to avoid the risk of losing steering control.
182
A "balanced" rig is easier to operate and contro l.
This means that the tow vehicle shou ld be loaded
to the extent possible and permissib le, wh ile
keep ing the trailer as light as possible under the
c ir cumstances. Whenever poss ible, transfer
some cargo to the luggage compartment of the
tow veh icle while observing tongue load require­
ments and vehicle load ing considerat ions .
Speed
The higher the speed, the more difficult it be­
comes for the driver to control the rig. Do not
drive at the maximum permissible speed. Reduce
your speed even more if load, weather or w ind
cond it ions are unfavorab le - particularly when
go ing downh ill.
Reduce veh icle speed
immediately if 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 tra ilers are lower than for regular
vehicles.
Always apply brakes early. When dr iving down­
hill, shift into 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 10 must
be observed carefully. If the needle moves close
to the upper end of the scale, reduce speed im­
med iately and/or turn off the air conditioner .
If the coolant temperature warning light . in
the instrument cluster starts flashing, pull off
the road, stop and let the engine
idle for about
two m inutes to prevent heat build-up .
&_ WARNING
Anyone not properly restrained in a moving
vehicle is at a much greater risk in an acci­
dent. Never let anyone ride in your car who is
not properly wearing the restraints provided
by Audi.

Engine oil consumption
The engine in your vehicle depends on an ade­
quate amount of oil to lubricate and cool all of
its moving parts .
In order to provide effective lubrication and cool­
i n g of internal engine components, all interna l
combustion engines consume a certai n amount
of oil. O il consumption var ies from engine to en­
g ine and may change significant ly ove r the life of
194
the engine. Typically, eng ines with a specif ied
break-in period (see
¢ page 177) consume mo re
o il dur ing the b reak -in per iod than they consume
after oil consumption has stabili zed.
U nder normal cond itions , the rate of oi l con ­
s u mption depends on t he qu ality and viscosity of
the oil, the RPM (revolutions per minute) at
which the engine is operated, the ambient tem ­
perature and road condit ions. Further factors are
