,&_ WARNING
-Sensors have dead spaces in which objects
cannot be detected. Be especia lly alert for
small children and animals, since they are not always detected by the sensors.
- The acoustic parking system is not a substi­
tute for the dr iver's own caution and alert­
ness. Ultimate respons ibility always remains
with the driver during parking and sim ilar
maneuvers . Always watch where you are
dr iv ing .
- You should always adjust the volume and
frequency of the warning tones so that you
can eas ily hea r the acoustic distance wa rn­
ing even if the radio is p lay ing, the air-cond i­
tioner blower is on High or there is a high
level of ou ts ide no ise .
- Check the settings whenever anyone e lse
has driven the vehicle before you.
(D Note
- Remember that low obstacles for which a
warning has already been issued may "dive"
below the system's sensing zone if the vehi­
cle is being backed up closer. In this case,
the war ning sound shutting off does
not in­
dicate that you have cleared the obstacle.
Instead, impact is imm inent.
- Objects such as tra iler hitches, chains, nar­
row posts or fences cove red by a th in laye r
of pa int may not always be detected by the
system. They can still damage your vehicle
wi thout warn ing.
{O) Tips
Keep the senso rs in the rear bumper clean
and free of snow and ice so that t he acous tic
parking assist sys tem can f unction properly.

- Several layers of heavy clothing may inter­
fere with correct positioning of belts and re­
duce the overall effectiveness of the system.
- Always keep belt buckles free of anything
that may prevent the buckle from latching
securely .
- Never use comfort clips or devices that cre­
ate slack in the shoulder be lt . However, spe­
cial clips may be requ ired for the proper use

Safe ty belts
Autom ati c s afet y belt retr actors
Every safety belt is equ ipped with an automa tic
be lt retractor on the shoulder belt. This feature
locks the belt when the belt is pulled out fast,
during hard braking and in a n accident . The belt
may a lso lock when you drive up or down a steep
hill or through a sharp curve. Dur ing normal driv­
ing the belt lets you
move freely .
Safety belt p ret en sion ers
The safety belts are equipped with a belt preten­
sioner that helps to t ighten the safety belt and
remove slack when the pretensioner is activated.
The function of the pretensioner is mon itored by
a warning light
r:::') page 19.
Convertib le loc king retracto r
Every safety be lt except the one on the driver
seat is equipped with a convertible locking retrac­
tor that
mus t be used when the safety belt is
used to attach a child safety seat. Be sure to read
the impo rtant information about this feature
c:;, page 167.
.&_ WARNING
Imprope rly pos itioned safety be lts can cause
ser ious injury in an accident
c:;, page 134,
Safety belt position.
- Safety belts offer optimum protection only
when the seatback is upright and belts are
properly positioned on the body.
- Always make sure that the rear seat back­
rest to which the center rea r safety belt is
attached is secure ly latched whenever the
rear center safety belt is being used. If the
backrest is not securely latched, the passen­
ger will move forward with the backrest dur­
ing sudden braking, in a sudden maneuver
and especially in a crash.
- Never attach the safety belt to the buckle for another seat. Attaching the belt to the
wrong buckle will reduce safety belt effec­
tiveness and can cause serious persona l in­
jury.
- A passenger who is not properly restrained can be seriously in jured by the safety be lt it­
self when it moves from the stronger parts
134
of the body into critical areas like the abdo­ men.
- Always lock the convertible locking retractor
when you are securing a child safety seat in
the vehicle
c:;, page 169.

Fuel and Refueling
the tank is full . Do not try to add more fuel
because fuel may spill out. In addition, the
expansion space in the fuel tank will be filled -
causing the fuel to overflow when it becomes
warm and pollute the environment.
(D Tips
- Running your engine while refuelling may
cause vapors to escape or even cause fuel to
sp ill out of the tank. This would then shut
off the fuel nozzle before the tank is full.
- Do not refuel your vehicle with the ignition
turned on. The fuel gauge may otherwise
not indicate the correct fuel level after refu­
elling .
- The fuel filler flap of your vehicle is not
l ocked when you lock the veh icle from the
inside .
Unlocking the fuel filler flap by hand
You can open the fuel filler flap by hand if the
power locking system should fail.

0 ::..:: co ..... ..... today's automobiles, have steadily reduced the
scope of maintenance and repairs which can be
carried out by vehicle owners.
Also, safety and
environmental
concerns place very strict limits
on the nature of repairs and adjustments to en­
gine and transmission parts which an owner can perform .
Maintenance, adjustments and repairs usually re­
quire special tools, testing devices and other
equipment available to specially trained work ­
shop personnel in order to assure proper per­
formance, reliability and safety of the vehicle and its many systems.
Improper maintenance, adjustments and repairs
can impair the operation and reliability of your
vehicle and even void your vehicle warranty .
Therefore, proof of servicing in accordance with
the maintenance schedule may be a condition for upholding a possible warranty claim made within
the warranty period.
Above all , operational safety can be adversely af­
fected, creating unnecessary risks for you and
your passengers.
If in doubt about any servicing, have it done by
your authorized Audi dealer or any properly equipped and qualified workshop. We strongly urge you to give your authorized Audi dealer the
opportunity to perform all scheduled mainte­ nance and necessary repairs. Your dealer has the
facilities, original parts and trained specialists to keep your vehicle running properly .
Performing limited maintenance yourself
The following pages describe a limited number of
procedures which can be performed on your vehi­
cle with ordinary tools, should the need arise and
trained personnel be unavailable. Before per­
forming any of these procedures, always thor­
oughly read all of the applicab le text and careful­
ly follow the instructions given . Always rigorously
observe the
WARNINGS provided .
Before you check anything in the engine com­
partment, always read and heed all WARNINGS
c::> .&. and c::> .&. in Working in the engine compart­
ment on page 203 .
Consumer information
A WARNING
-Serious personal injury may occur as a result
of improperly performed maintenance, ad­
justments or repairs .
- Always be extremely careful when working
on the vehicle. Always follow commonly ac­
cepted safety practices and general com­
mon sense. Never risk personal injury.
- Do not attempt any of the maintenance,
checks or repairs described on the following pages if you are not fully familiar with these
or other procedures with respect to the ve­ hicle, or are uncertain how to proceed.
- Do not do any work without the proper tools
and equipment. Have the necessary work
done by your authorized Audi dealer or any
properly equipped and qualified workshop.
- The engine compartment of any motor vehi­
cle is a potentially hazardous area. Never
reach into the area around or touch the radi­
ator fan. It is temperature controlled and
can switch on suddenly - even when the en­
gine is off and the ignition key has been re­
moved. The radiator fan switches on auto­
matically when the coolant reaches a certain
temperature and will continue to run until
the coolant temperature drops.
- Always remove the ignition key before any­
one gets under the vehicle.
-Always support your vehicle with safety
stands if it is necessary to work underneath
the vehicle. The jack supplied with the vehi­
cle is not adequate for this purpose and
could collapse causing serious personal in­
jury.
- If you must work underneath the vehicle
with the wheels on the ground, always make
sure the vehicle is on level ground, that the
wheels are always securely blocked and that
the engine cannot be started.
- Always make sure the transmission selector
lever (automatic transmission) is in "P"
(Park position) or Neutral (manual transmis-
sion) and the park brake is firmly applied . ..,.
