fig . 194 t o activate the A udi pa rking system m anually .
Activation of the acoustic parking system is confirmed by
a brief acknowledgement sound . The indicator lig ht in
the switch lights up.
D ea ctivation
If you drive forwards faster tha n approx. 6 mph (10 km/h),
or
- if you switch the ign ition off, the entire acoustic parking
assist is automatically deactivated, or
- you can press the sw itch
P111! i n the center console
=> page 173, fig. 194 to deact ivate the Audi parking
system. The indicator light in the switch goes out.
You have to turn on the acoustic parking assist m anuall y if you wish
to park the vehicle forwards or if you w ish to approach an obstacle
forwards and want a distance warning .
The range at which the sensors start to measu re is
about:

Distance warning is given by chimes which are generated by a
signal generator . The volume and the pitch of the chimes can be
adjusted in the MMI => page
183.
Mute
In the case of vehic les with automa tic transmission, an acoustic
distance warning is discontinued when the transmission selector l
ever is moved to the P position. However, the system remains
active . As soo n as the selector lever is moved from the
P posi tion
and the vehicle approaches an obstacle, the acoustic distance
warning resumes .
Dri ving fo rward/ba ckvv ard
Distance warning when driving forward/backward is based o n
detection of an obstacle in the range of the parking assist . As the
distance dec reases, the time interval between the audible tones
becomes shorter.
When the distance is less than approx . 1 ft (0.30 m), the tone
becomes continuous. At this point you shou ld s top backing up or
driving forward .
If the distance to an obstac le remains the same, the vo lume of the
distance warning is gradually reduced after about
4 seconds (does
not app ly to the zone for the cont inuous tone). If you sta rt to
approach the detected obstacle again, the distance warning will
sound at the normal volume again .
P a rk ing
When you selec t ano ther gear when parki ng (e .g . reverse/forward),
the warning tones are temporarily suppressed, but the visual display remains on the MMI display . If you start approaching a
detected obstacle again, the distance warning wi ll sound at the
normal vo lume again .
Visual disp lay
T he segments on the MMI display indicate a change in the distance
between the vehicle and an obstacle . The number of segments
displayed depends on the obstacles in front of or behind the
vehic le. The c loser the vehic le comes to the obstacle, the closer the
segments approach the vehic le => page
173 , fig. 195. When the
segment before last is disp layed, the veh icle has reached the colli­
sion zone. At this point you should stop backing up or driving
forward =>

& WARNING
• Sensor s have dead spaces in which obje cts cannot be
detected. Be e spe cially careful to check for small children and
an imals before ba cking up . Small children and animals will not
always be detected by the sensors.
• The Audi parking system is not a substitute for being careful
and alert when backing up. Be e spe cially careful during parking
and similar maneuvers . Always watch where you are dri ving and
make sure that nothing is in the way.
• Remember that low ob sta cles which have already been
s ignaled may pass below the system' s sen sing zone when the
v ehi cle is ba cking up . The fa ct that the signal stops doe s not mean
that you have cleared the obstacle . When the signal stops , impact
is imminent . Obje cts su ch as trailer hit che s, chain s, narrow posts
or fences covered by a thin l ayer of paint may not always be
detected by the sy stem. They can still damage your vehicle
without warning .
• Alway s make sure that the volume and frequency of the chime s
is adjusted so that you can eas ily hear the acoustic distance signal
even if the radio is playing , the air -conditioner blower is on High or
there is a high level of out side noise .
- Check the setting s whenever someone else has dri ven the
vehicle before you.
• Improper relian ce on the Aud i parking sy stem can cau se colli ­
sions and serious per sonal injury .
- Never rely only on parking assi st when ba cking up .
- Always check rear view mirrors to make sure it is safe to back
up .

Overheating
of brakes
To prevent the disc brake of the braked wheel from overheating if
subjected to excessive loads, the EDL cuts out temporarily . The
vehicle remains operational and behaves in the same way as a
vehicle without EDL.
As soon as the brake has cooled down, EDL switches on again auto ­
matically.
& WARNING
• When accelerating on slippery surfaces, such as on ice or snow,
always be careful when depressing the accelerator pedal. Even
with the EDL working, the drive wheels can spin and reduce your ability to control your car. Risk of crash!
• The increased safety afforded by EDL does not mean that you
can take safety risks . Always adapt your driving style to the road
conditions and traffic situation.
[ i] Tips
If a fault occurs in the ABS, the EDL is also not functioning. This is
indicated by the ABS warning light=>
page 21. •
Anti-Slip Regulation System (ASR)
The Anti-Slip Regulation System prevents the driven
wheels from spinning when the car is accelerating.
General notes
The Anti-Slip Regulation System (ASR) is integrated in the electronic
stabilization program (ESP). When the vehicle starts up and acceler­
ates, the wheels are prevented from spinning by adjusting the
engine power to match the amount of grip available from the road
surface.
How the system works
ASR performs automatically, i.e. without the driver's intervention.
With the aid of the ABS sensors=>
page 274, ASR monitors the
speed of the driven wheels. If the wheels start to spin, the engine
power is reduced automatically until the tires find enough grip to
lock onto the road surface. The system is active across the entire
speed range.
The ASR works in conjunction with the ABS. If a malfunction should
occur in the ABS, the ASR will also be out of action.
& WARNING
The increased safety afforded by ASR does not mean that you can
take safety risks. Always adapt your driving style to the road
conditions and traffic situation.
[ i] Tips
To ensure that the ASR works properly, all four wheels must be fitted
with identical tires Any differences in rolling radius of the tires can
cause the system to reduce engine power when this is not desired.

Braking
General information
What affects braking efficiency?
Operating conditions and driving habits
The brakes on today's automobiles are still subject to wear,
depending largely on operating conditions and driving habits=>& .
On vehicles that are either driven mostly in stop-and-go city traffic
or are driven hard, the brake pads should be checked by your autho ­
rized Audi dealer more often than specified in the
Warranty & Main- ~

___ D_ r_iv _ in_... g"'- a_ n_ d_ e_ n_ v_i_r _o _n_ m_ e_n_ t _______________________________________________ _
New brake pads
--
Remember that new brake pads do not have a full braking
effect during the first 250 miles (400 kilometers) after they
are installed .
New brake pads have to be "burnished in" before they have optimal
grab =>& .
During the break -in period, you should avoid putting severe loads
on the brakes . Severe loads include, for examp le, sudden hard
braking, in particular at very high speeds or, for example, on moun­
tain passes.
& WARNING
New brake pads don't have the best stopping power and must be
"broken-in" during the initial 100 to 150 miles (150 to 200 kilome­
ters) of normal city driving. You can compensate for this by
pressing the brake pedal more firmly . This also applies later when
new pads are installed.
:J
Catalytic converter
It is very important that your emission control system
(catalytic converter) is functioning properly to ensure that
your vehicle is running in an environmentally sound
manner.
- Always use lead-free gasoline:=> page 303, "Fuel supply".
- Never run the tank down all the way to empty.
- Never put too much motor oil in your engine ==>
page 314,
"Adding engine oil 't=:;r\11
•
Never try to push- or tow-start your vehicle.
The catalytic converter is an efficient "clean-up" device built into the
exhaust system of the vehicle. The catalytic converter burns many
of the po llutants in the exhaust gas before they are released into the
atmosphere.
The exclusive use of unleaded fuel is critically important for the life
of the catalytic converter and proper functioning of the engine.
& WARNING
• Do not park or operate the vehicle in areas where the hot
exhaust system may come in contact with dry grass, brush, fuel
spill or other material which can cause a fire .
• Do not apply additional undercoating or rustproofing on or
near the exhaust manifold, exhaust pipes, catalytic converter or
heat shields. During driving, the substance used for undercoating
could overheat and cause a fire .
0 Note
• Be aware that just one tank filling with leaded fuel will alr eady
seriously degrade the performance of the catalytic converter.
• Do not exceed the correct engine oil level=>
page 314.
• Do not drive until the fuel tank becomes completely empty. The
engine could misfire. Unburned fuel could also get into the exhaust
system and this could cause the catalytic converter to overheat.
• Do not turn off the ignition while the vehicle is moving.
• Do not continue to operate your vehicle under these conditions,
as otherwise fuel can reach the catalytic converter. This could result
in overheating of the converter, requiring its replacement .
• To assure efficient operation of the Emission Control System:
- Have your vehicle maintained properly and in accordance with
the service recommendations in your Warranty
& Maintenance
booklet. •
