Before the starter can be operated again the key must be turned
back to position
G) . The non-repeat lock prevents you from
damaging the starter when the engine is running.
_& WARNING
• Never remove the key from the ignition lock while the vehicle is
moving. The steering wheel will lock causing loss of control.
• If you have to leave your vehicle-even for just a minute- always
remove the ignition key and take it with you. This is especially
important if you are going to leave children behind in the vehicle.
The children could start the engine or use other vehicle controls.
Unsupervised use of vehicle controls (for example, power
windows) can cause serious personal injuries.
[ i] Tips
If the vehicle battery has been disconnected and then reconnected,
then you must leave the key in position
0 for about 5 seconds
before you can start the engine. •
Ignition key safety lock
The ignition key can only be removed when the selector
lever is in the
"P" (Park) position.
After switching off the ignition, the ignition key can only be
removed from the ignition lock when the selector lever is in the
"P"
(Park) position. After you have removed the key, the selector lever is
locked and cannot be moved. •
Starting and stopping the engine
Starting the engine
The engine can only be started with your original Audi
key.
-Set the parking brake.
-Move the selector lever to the neutral position (automatic
transmission: selector lever in P or N)
=> & .
-On vehicles with manual transmission, fully depress the
clutch pedal.
-Turn the ignition key to position 0 => page 135, fig. 143
- do not depress the gas pedal when starting the engine!
-Let go of the key as soon as the engine starts.
A cold engine may at first be loud after it has been started. This is
due to the hydraulic valves building up the oil pressure . This is
normal and no need for concern.
If the engine does not start immediately, stop trying after 10
seconds and then try to restart the engine about 30 seconds later.
What to do if the engine does not start
• ~ page 330
• ~ page 332, "Emergency towing with commercial tow truck"
_& WARNING
Never start or let the engine run in a confined or enclosed area.
Exhaust fumes from the engine contain carbon monoxide, a color­
less and odorless gas. Carbon monoxide can be fatal if inhaled.
• Never leave the engine idling unattended. An unattended
vehicle with a running engine poses a danger of personal injury or
theft.

&, WARNING (continued )
• Before des cending a steep grade , reduce speed and shift trans­
mi ssion into a lo wer gear or lower driving po sition . Do not ride the
brake s or hold the pedal down too long or too often . This could
cau se the brake s to get hot and dimini sh braking efficiency .
• Do not ride the brakes by resting your foot on the ped al when
you do not intend to brake. This may cause the brakes to overheat, premature wear and in creased stopping distan ce.
• Under certain climati c and operating conditions such a s
passing through water, driving in heavy rain or after washing the
v ehicle , the effectiveness of the brakes can be reduced . In winter ,
ice can a ccumulate on the brake pads , linings , discs and drums .
Cautiously apply brakes for a te st. Brakes will dry and ice coating s
will be cleaned off after a few cautious brake applicat ions .
• Driving for an extended period of time on salt-co vered roads
without using your brakes can also affect braking effi ciency . Clean
off accumulated salt coating from brake discs and pads with a few
c autious brake appli cations .
• If you damage the front spoiler , or if you install a different
spoiler , 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 . Avo id driving the
vehicle and have it towed to the nearest Audi dealer or qualified
workshop .•
Brake booster
T he brake booster add s ex tra braking power.
The bra ke booster works wit h vacuum pressure which is created
only whe n th e e ng in e is
runn ing=> &,.
& WARNING
• Never let the vehi cle roll to a stop with the engine 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 pre ssed considerably harder to
make up for the lack of booster assistance . •
Functioning of Anti-Lock Brake System (ABS)
A BS preven ts th e wh eels fr om lock ing up und er b rak ing.
T he ABS contributes effectively to vehicle contro l since it prevents
th e w heels from
lo cki ng w he n t he brakes a re a ppli ed. T h is mea ns
that the vehicle remains steerable and is less likely to skid.
With ABS you do not need to pump the brake . Just hold the brake
pedal down .
However, do not expect that the ABS shortens braking distance
u nder all circum sta nces. Whe n driving o n gravel or on newly fa lle n
snow on top of icy surfaces, braking distance may be even longer,
t herefore, under these ci rcums tances, it is espec ial ly i mpo rtant th at
you driv e slowly and with great care.
How the ABS system works
An automatic check is made when a speed of about 4 mph (6 km/h)
i s r eac hed . Wh en th is happe ns, a pumpi ng noi se can be hea rd.
I f a n indiv idual wheel be gins to rotat e too slowly i n relation to
vehic le speed and tends to lock, the ABS automatical ly reduces
brake pressur e to prevent tha t whee l from loc king .
Th is a utomatic adjustment process wi ll cause a
slight vibration of
t he brake peda l a nd s om e noi ses t o a lert y ou th at ve hicle spee d
must be adapted to existing road and traffic conditions. _..

New brake pads
Remember that new brake pads do not have a full braking
effec t during the first 250 miles (400 kilometers) after they
are i nstalled .
New brake pads have to be "burn ished in" befo re they have opti mal
grab =>& .
During the break -in period, you s hou ld avo id putti ng severe loads
on the brakes . Severe loads include, for examp le, sudden hard
braking, in particular at very h igh speeds or, for example, on moun ­
t ain passes .
& WARNING
New brake p ad s don't h ave th e be st sto pping p ower a nd mu st b e
" brok en -in " durin g th e initial 100 to 1 50 mil es (150 t o 200 kil ome ­
t e rs) of norm al cit y dri ving . You can comp en sa te for thi s by
pr ess ing the brak e ped al mor e firmly . Thi s al so appli es later when
ne w pad s a re in sta lled. •
Catalytic converter
It is very important that your emission control sys tem
(catalytic conver ter) is functioning properly to ensure that
y o ur vehicle is running in an environmentally sound
manner.
-Always use lead-free gasoline => page 267, "Fuel supply".
-Never run the tank down a ll the way to empty.
-Never put too much motor o il in your engine => page 278,
"Add ing eng ine oil -Neve r try to push -or tow -s ta rt yo ur vehic le.
The catalytic converter is an efficient "clean-up " device built into the
exhaust system of the vehicle. The catalyt ic converter burns many
of the po llutants in the exhaust gas before they are released into the
atmosphere.
T he exc lusive use o f un leaded fue l is critica lly important for the l ife
of the catalytic converter and proper functioning of the engine.
& WARNING
• Do not park or operate th e veh icle in ar eas wh ere the hot
ex hau st sys tem m ay come in contac t w ith dr y gra ss, bru sh , fuel
s pill or other material which can cau se a fire .
• Do not appl y additi ona l under coating or ru stpr oofing on or

he at shield s. Du ring dri ving , the sub sta nce u sed f or under coating
c ould overhe at and cau se a fir e.
0 Note
• Be aware that just one tank filling with leaded fue l wi ll already
ser iously degrade the performance of the catalyt ic converter.
• Do not exceed the correct engine oi l
level=> page 278.
• Do not drive until the fuel tank becomes comp letely empty . The
engine could misfire . Unburned fuel could also get into the exhaust
system and this could cause the catalytic conver ter to overheat .
• Do not turn off the ignition wh ile the vehicle is moving.
• Do not continue to operate your vehicle under these conditions,
as otherwise fuel can reach the cata lyt ic converter . This cou ld result
in overheating of the converter, requiring its rep lacement .
• To assure eff icient operat ion of the Em iss ion Control System:
- Have your vehicle maintained properly and in accordance with
the service recommendations in your Maintenance
& Warranty
booklet.

- Lack of proper maintenance as wel l as improper use of the
vehic le wi ll impair the func tion of the emission control system
and cou ld lead to damage .
<£> For the sake of the envir onm ent
Even when the Emission Control System is operating properly, the
exhaust gas can have a su lfur -like exhaust gas sme ll under some
operat ing states . Th is depends on the sulfur content of the fuel
being used. Using a different brand of fue l may he lp, or fil ling the
tank with lead -free super grade gasol ine. •
Avoid damaging the vehicle
When you are driving on poor roads, or over curbs, steep ramps,
e tc., make certain that low- lying parts such as spoilers and exhaust
system parts do not bottom out and get damaged.
This is especial ly true for vehicles with low -s lung chassis (sports
chassis)* and ful ly loaded vehicles .•
Operate your vehicle economically
and minimize pollution
General
Y o ur personal style of driving will determine the economy
of your vehicle, as well as exhaust and noise levels.
Fuel economy, env ironmental impact, and wear on your engine,
brakes and t ires largely depend on three factors :
• your personal driving sty le
• operat ing cond it ions
• technica l limitat ions
Controls and equip­
ment Safety first Vehicle operation
If you anticipate what you need to do next and drive economica
lly,
you can easily cut your fuel consumptio n by 10 -15 percent . This
section wil l give you some tips on how you can help the environ­
ment and your pocketboo k.
[ i ] Tips
The cons umption estimates as pub lished by ENV IRO NM EN TAL
PRO TECTION AGENCY (EPA) and Transport Canada may not corre ­

depending upon veh icle load and speed, road and weather condi ­
tions, trip length, etc. •
Drive smoothly and keep a lookout ahead
Vehicles use the most fuel when they ore accelerating .
-Avoid unnecess ary accelerating and brak ing.
Vehic les use the most fue l when they are accelerating . If you ant ici ­
pate what is going to happen ne xt, you wi ll need to brake less and,
thus , acce lerate less. Let the vehicle coast whenever poss ib le -for
examp le when you see that the next traffic light is red. •
Avoid full throttle
Driving at moderate speeds saves fuel and improves your
mileage.
- Try and keep we ll below your car 's max imum speed.
Acce lerating gent ly reduces fue l consump tion , engine wear, and
does no t disturb the environme nt.
Fue l consumption, exhaust emissions and engine noise increase
disproportionately at h ig h speeds . If you drive at approx imate ly
three quarters of top speed, fuel consumpt ion wil l be reduced by _,,,

one half. Never drive faster than the posted speed limit and weather
conditions permit. •
Reducing unnecessary idling
Even when your car is just idling it burns up fuel.
- Shut the engine off when you are not driving the vehicle .
- Do not warm up the vehic le by letting the engine run at
id le .
It makes sense to shut off the engine in traff ic jams, when waiting
for tra ins to pass at rai lroad crossings , or at traffic lights that have
long waits on red. Turning the engine off for just 30 -40 seconds
saves more fue l than is burned starting the engine again .
It takes a long time for the engine to warm up fu lly when it is
running at idle. However, wear and noxious emiss ions are espec ially
high when the engine is warming up . So you should drive away as
soon as you sta rt the engine and avoid running at high rpms w hile
the engine is sti ll warming up.
0 Note
Do not leave engine idling unattended after starting . If warning
lights should come on to indicate improper operation, they would
go unheeded. Extended id ling also produces heat, which could
resu lt in overheating or other damage to the vehic le or other
property .•
Regular maintenance
A badly tuned engine unnecessarily wastes a lot of fuel.
- Have your ve hicle serviced at regular intervals .
By having your vehicle regularly serviced by an Audi dealer helps to
ensure that it runs properly and economical ly . The cond ition of your
vehic le not only affects its safety and abi lity to hold its value, it also
affects
fuel consumpt ion .
Check your oil ea ch time you fill your t ank .
The amount of oil used is related to engine load and speed.
I t is norma l for the oi l consumption of a new engine to reach its
lowest value after a certain mi leage has been driven.
You must drive your vehicle about 3,000 miles (5,000 kilometers) before you can properly assess oil consumption .
This also applies to fue l consump tion and engine output .
0 Note
• Have your vehicle maintained properly and in accordance with
t he service recom mendat io n s in your Maintenance
& Wa rranty
booklet. Lack of proper ma intenance as well as improper use of the
vehic le wi ll impai r the function of the emission cont rol system and
cou ld lead to damage.
• Do no t alte r or remove any component of the Emission Contro l
System unless approved by the manufacturer .
• Do not alte r or remove any dev ice, such as heat shields,
switches, ignition wires, valves, which are designed to protec t your
vehic le's Emission Control System and other important veh ic le
components .•
Fewer short trips
Fuel consumption will alw ays be rel atively high on short
t r ips.
- Try to avo id driving short dis ta n ces wi th a cold engine. ~

Safety belts
Only well-maintained safety belts work reliably when
needed.
- Keep belts clean.
- For cleaning, use a mild soap and water solution. Let
belts dry thoroughly and away from direct sunlight.
- Do not allow inertia reel safety belts to retract before
they are completely dry.
- Check the condition of your safety belts
regularly.
Heavily soiled safety belts may not retract properly.
& WARNING
Damaged safety belts can break in a crash.
• Anything that might damage your safety belts could mean that
you and your passengers would not be adequately protected in an
accident.
• Safety belt performance depends on correct installation. Never
remove belts from the vehicle to clean them.
• Do not use chemical cleaning agents, bleach or dyes. They have
corrosive properties which weaken the webbing.
• When cleaning your safety belts, inspect them for damage. If
you discover damage, see your Audi dealer.
• Always read and heed all WARNINGS and the information
=> page 254. •
Engine compartment
Be especially careful when cleaning the engine compart­
ment.
Always switch off the ignition before cleaning the engine => &.
Plenum panel
Remove leaves from the plenum panel in front of the windshield
under the engine hood. This prevents the water drain holes from
becoming blocked, and it prevents debris from entering the vehicle
interior through the heating and ventilation ducts .
Corrosion protection
The engine compartment and transmission have been corrosion­
protected at the factory.
Good anti-corrosion treatment is very important, particularly in the
winter. If the vehicle is frequently driven on salt treated roads, the
entire engine compartment and plenum panel should be thor ­
oughly cleaned at the end of winter and retreated to prevent salt
damage. At the same time, the underside of the vehicle should be
washed as well.
If the engine compartment is cleaned at any time with grease
removing solutions
21 , or if you have the engine washed , the anti­
corrosion treatment is almost always removed as well. It is therefore
essential to have a long-lasting corrosion protection reapplied to all
surfaces, seams, joints and components in the engine compart ­
ment.
& WARNING
Be aware: the engine compartment of any motor vehicle is a
potentially hazardous area.
• Before working in the engine compartment, be sure to read the
information
=> page 265 . .,,_
21 Use only the corr ect cleaning solutions. Never use gasoline or diesel fuel.
