aids
General notes
Applies to vehicles: with rear parking aid/parking system
plus/park assist
Various systems are available to help you when
parking or manoeuvring in tight spaces, depend­
ing on the equipment fitted on your vehicle.
The rear parking aid gives an acoustic warning if
there are any obstacles behind the car
¢page 93.
When you are parking, the parking system plus
warns you acoustically and optically about obsta­
cles detected in front of and behind the vehicle
¢ page 94. On vehicles with park assist, the
area detected at the side of the vehicle ®
¢page 94, Fig. 101 is also monitored.
The park assist helps you to find suitable parking
spaces, to manoeuvre the vehicle into spaces par­
allel or perpendicular to the roadside and to drive
out of spaces parallel to the kerb ¢ page 95.
.&_ WARNING
- Always watch the road and the area sur­
rounding the vehicle. The electronic systems
cannot replace the full concentration of the
driver. The driver is always responsible for
safety during parking and all other manoeu­
vres.
- Please note that certain surfaces, such as
clothing fabrics, cannot be detected or dis­
played by the system -risk of accident!
- Sensors have blind spots in which neither
people nor objects are registered. It is par­
ticularly important to ensure that there are
no small children or animals near the vehi­
cle -risk of accident!
- Always keep a close watch on the area
around the vehicle and make full use of the
rear-view mirrors.
CD CAUTION
- The system may not always be able to de­
tect objects such as the following:
- Chains, trailer draw bars, posts or fences Parking
aids
- Objects above the sensors, such as wall
protrusions, etc.
- Objects with certain surfaces or struc­
tures, such as wire fences or powder snow
- As your car moves closer to low obstacles,
they may disappear from the sensors' field
of vision. Please note that you will no longer
be warned about these obstacles.
- Impacts or damage to the radiator grille,
bumper, wheel arches or underbody can
cause misalignment of the sensors. This can
impair the effectiveness of the parking aids.
Have the systems checked by a qualified
workshop.
{D) Note
- In certain situations, a warning may be giv­
en by the system even if there is no obstacle
within range of the sensors. This can be
caused by the following, for instance:
- Certain road surfaces or long grass
- External ultrasound sources, e.g. from
street cleaning vehicles
- Heavy rain or snow or dense exhaust
fumes
- To familiarise yourself with the system, we
recommend that you practise parking in a
quiet location or a car park. The weather
and light conditions should be good.
- You can adjust the volume of the beeps.
- To ensure that the acoustic parking aid
works properly, the sensors must be kept
clean and free of snow and ice.
- There is a slight delay in the picture display.

Fuel Petrol grade
Applies to vehicles: with petrol engine
The correct grade of petrol is listed inside the
fuel tank flap.
The vehicle is equipped with a catalytic converter
and must only be run on unleaded petrol. The
petrol must comply with the EN 228 or DIN
51626-1 standard and must be sulphur-free. You
can fuel your vehicle with fuels containing a max­
imum of 10% ethanol (ElO). The petrol grades
have different octane ratings (RON).
The following headings relate to the sticker on
the inside of your vehicle's tank flap:
Unleaded fuel only RON/ROZ 95 Super,
Premium or min. RON/ROZ 91 Normal
The use of premium petrol (95 RON) is recom­
mended. If that type of fuel is not available, reg­
ular petrol (RON 91) can be used with a slight
loss of power.
Unleaded fuel only, min. RON/ROZ 95 Super,
Premium
Premium petrol (at least 95 RON) must be used.
If premium petrol is not available, the engine can
be run on regular petrol with 91 RON as an emer­
gency measure. In this case only use moderate
engine speeds and a light throttle. Fill up with
premium or Super Plus petrol as soon as possi­
ble.
Unleaded fuel only RON/ROZ 98 Super Plus
or min. RON/ROZ 95 Super, Premium
The use of Super Plus petrol (98 RON) is recom­
mended. If that type of fuel is not available, pre­
mium petrol (RON 95) can be used with a slight
loss of power.
If premium petrol is not available, the engine can
� be
run on regular petrol with 91 RON as an emer-
>
� gency
measure. In this case only use moderate

CD CAUTION
- Do NOT fuel your vehicle with high-ethanol
fuel blends (e.g. ESQ or E85). This will dam­
age the fuel system.
- Just one tank of leaded fuel or fuel with
metallic additives will permanently impair
the efficiency of the catalytic converter.
- You should use only petrol additives which
have been approved by Audi. Additives with
so-called octane boosters or antiknock addi­
tives can contain metallic additives that
cause significant damage to the engine and
the catalytic converter. Do not use such ad­
ditives.
- Metal-based fuels, which can be identified
from the marking on the fuel dispenser,
must not be used. LRP fuel (lead replace­
ment petrol) also contains high concentra­
tions of metallic additive. Risk of engine
damage!
- High engine speed and full throttle can
damage the engine when using petrol with
an octane rating lower than the correct
grade for the engine.
«'.D Note
- You can use higher octane fuel than your en­
gine requires.
- In countries where sulphur-free fuel is not
available, you may use low-sulphur fuel in­
stead.
Diesel fuel
Applies to vehicles: with diesel engine
Please note the information on the inside of the
fuel tank flap.
The use of sulphur-free diesel to EN 590 is rec­
ommended. If that type of fuel is unavailable,
diesel to EN 590 can be used. It must have ace­
tane number (CN) of at least 51. The cetane
number indicates the ignition quality of the die-
sel fuel.

systems
Catalytic converter
Applies to vehicles with petrol engine: The vehi­
cle must only be used with unleaded petrol; oth­
erwise the catalytic converter will be irreparably
damaged.
Never allow the fuel tank to run completely dry,
as the irregular supply of fuel can cause misfir­
ing. This allows unburnt fuel to enter the exhaust
system, which can cause overheating and dam­
age to the catalytic converter.
Diesel particulate filter
Applies to vehicles with diesel engine: The die­
sel particulate filter can filter out almost all soot
particles contained in the exhaust gas. In normal
driving conditions the filter is self-cleaning.
Should the self-cleaning function of the filter not
be able to operate, e.g. when the vehicle is con­
tinuously used only for short trips, the filter be-
220 comes
obstructed with soot and the symbol Cl
for the diesel particulate filter lights up
¢page 15.
A WARNING
The exhaust system is very hot when the vehi­
cle is being driven and after the engine has
been switched off.
- Never touch the tailpipes when they are hot
- risk of burns!
- Because of the high temperatures which can
occur in the emission control system (cata­
lytic converter or diesel particulate filter),
do not park the vehicle where the exhaust
can come into contact with flammable ma­
terials under the car (e.g. on grass or at the
forest edge) -risk of fire!
- Do not apply any undersea[ agents in the
area around the exhaust system -risk of
fire!
Engine compartment
Working on components in the engine
compartment
Extra caution is necessary when working on com­
ponents in the engine compartment.
Always be aware of the danger of injury and
scalding as well as the risk of accident or fire
when working in the engine compartment (e.g.
when checking and refilling fluids). Always ob­
serve the warnings listed below and follow all
normal safety precautions. The engine compart­
ment of any motor vehicle is a potentially haz­
ardous area ¢ .,&.
A WARNING
- Switch off the engine.
- Switch off the ignition.
- Apply the parking brake.
- Pu t the gear lever in neutral or selector in P.

make sure that the anti-freeze concentra­
tion is adequate for the conditions to be ex­
pected. This applies particularly if you drive
into a colder climate zone.
- To prevent damage to the engine, do not
use a different type of anti-freeze additive if
the approved type of additive is not availa­
ble. In this case use only water and bring
the coolant concentration back up to the
correct level as soon as possible by putting
in the specified additive.
- Always top up with fresh, unused coolant.
- Radiator sealants must not be added to the
coolant.
Topping up coolant

Checking coolant level
.. Park
your vehicle on a level surface .
.. Switch off the ignition .
.. Read off the coolant level on the coolant expan­
sion tank ¢ page 222, Fig. 211. When the en­
gine is cold, the coolant level should be be­
tween the marks. When the engine is warm, it
may be slightly above the top mark. Checking
and topping up fluids
Topping up coolant
Impor tant: The coolant expansion tank must not
be empty ¢(D.
.. Wait for the engine to cool down.
.. Cover the cap on the expansion tank with a
cloth, and carefully unscrew the cap anti-clock­
wise ¢ .&_ .
.. Add coolant in the correct concentration
¢ page 224 up to the top mark.
.. You should make sure that the fluid level re-
mains stable. If necessary, add more coolant.
.. Screw the cap on again tightly.
Any loss of coolant normally indicates a leak in
the cooling system. Drive to a qualified workshop
without delay and have the cooling system
checked. If there are no leaks in the system, a
loss of coolant can only occur if the coolant boils
and is forced out of the system as a result of
overheating.
A WARNING
- The cooling system is under pressure. Do
not unscrew the cap on the expansion tank
when the engine is hot: you could be scal­
ded by escaping steam.
- The coolant and coolant additive can be a
health hazard. Store the coolant additive in
the original container in a safe place out of
reach of children -risk of poisoning.
- When working in the engine compartment
be aware that the radiator fan may start
running suddenly, even if the ignition is
switched off-risk of injury!
CD CAUTION
Do not add coolant if the expansion tank is
empty. Air could have got into the cooling sys­
tem -risk of engine damage! In this case, do
NOT drive on. Obtain professional assistance .

Battery General notes
ALL work on batteries requires specialist knowl­
edge.
The battery is virtually maintenance-free. It is
checked as part of the Inspection Service.
When an airbag is triggered, the battery will, un­
der certain circumstances, be disconnected from
the on-board power supply for safety reasons
¢ .&.. in General notes on airbag system on
page 209.
Disconnecting the battery
The battery should always be Left connected. If
the battery is disconnected, some of the vehicle's
functions will become inoperative (e.g. electric
windows). These functions will require resetting
after the battery is reconnected. For this reason,
the battery should only be disconnected from the
vehicle's electrical system when absolutely nec­
essary.
If the vehi cle is not used for long periods
If you do not drive your vehicle for a period of
several days or weeks, the power management
will gradually shut off the on-board systems one
by one, or reduce the amount of current they are
using. This Limits the amount of power consumed
and helps to ensure reliable starting even after a
Long period ¢ page 106. Certain convenience fea­
tures, such as interior Lighting or electric seat ad­
justment, may not be available. These functions
will be restored when you switch on the ignition
and start the engine. Even though some systems
are deactivated automatically, certain electrical
equipment continues to draw current even when
the ignition is off. If the vehicle is Left standing
for several months, this can result in total bat-
tery discharge. If the battery is allowed to dis­
charge completely, an internal chemical reaction
