Fuel has entered the engine oil due to low out­
side temperatures or frequent short trips. Drive
until the engine is warm to allow the fuel to
evaporate out of the engine oil. When doing so,
avoid high engine speeds, full acceleration and
heavy engine loads.

WARNING

- When applying
the
brakes
to
clean
off
de­
posits
on the
pads and discs, select
a
clear,
dry
road.
Be sure
not to
inconvenience
or
en­
danger other road users;
do not
risk an
acci­

dent.
- Never
let the car
coast with
the
engine
switched
off
(this can cause accidents).

(T)
CAUTION

- Never
let the
brakes "drag"
by
leaving your
foot on
the
pedal when you
do not
really
in­

tend
to
brake. This overheats
the
brakes,
re­

sulting
in
longer stopping distances
and

greater wear.
- Before driving down
a
long,
steep gradient,
it
is
advisable
to
reduce speed
and
select
a

lower gear.
In
this way you will make use
of

the engine braking effect and relieve
the

load
on the
brakes.
If
you
still have
to use

the brakes,
it is
better
to
brake firmly
at in­

tervals than
to
apply
the
brakes continuous-

Ly

-
If
the brake servo
is out of
action,
you must
apply considerably more pressure
to the

brake pedal than you normally would.
-
If
you
wish
to
equip
the
car with accessories
such as a front spoiler
or
wheel covers,
it is

important that
the
flow
of air to the
front
wheels
is not
obstructed, otherwise
the

brakes can overheat.

Electro-mechanical

power steering
Electro-mechanical power steering assists
the

driver when steering.
The degree
of
power assistance
is
adapted elec­

tronically,
depending
on the
speed.
Warning/indicator lamps
and
driver
messages
| Do not drive vehicle: steering defective
If the warning lamp lights
up
permanently
and

the message appears, there
may be
a power
steering failure.
Stop
the
vehicle
in a
safe place
as
soon
as
possi­

ble.
Do
NOT drive on. Obtain professional assis­

tance.

S
Steering malfunction: you can continue driv­
ing
If the indicator Lamp Lights up,
the
steering
re­

sponse
may be
heavier
or
lighter than usual.
In

addition,
it is
possible that
the
steering wheel
will
be off
centre when driving
in a
straight line.
Drive slowly
to
a qualified workshop and have
the

fault rectified.

You
can

Four-wheel drive
(quattro)
Applies to: vehicles with four-wheel drive

On
quattro models
the
engine power is distrib­
uted
to all
four wheels.
General notes
On four-wheel drive vehicles,
the
engine power
is

distributed
to all
four wheels. The distribution
of

power
is
controlled automatically according
to

your driving style and
the
road conditions. Also
refer
to
^>page
145,
Electronic stabilisation con­
trol
(ESC).

The four-wheel drive
is
specially designed
to

complement
the
superior engine power
of
your

Audi.
This combination gives
the car
exceptional
handling
and
performance capabilities
-
both
on

normal roads and
in
more difficult conditions,
such
as
snow and
ice.
Even
so (or
perhaps espe­
cially
for
this reason),
it is
important
to
observe
certain safety points

Checking and topping up fluids
- Never remove the engine cover panel - risk
of burns!
- If any tests have to be performed with the
engine running, there is an extra safety risk
from the rotating parts, such as the drive

belts,
alternator and radiator
fan,
etc., and
from the high-voltage ignition system.
- Never touch the radiator fan. The electric
additional fan is controlled by temperature
and can start running without warning.
- Applies to vehicles with automatic gearbox:
Never open the throttle inadvertently (for
instance by hand from the engine compart­
ment) if
a
gear is engaged while the vehicle
is stationary with the engine running. The
vehicle will otherwise start moving immedi­
ately and could cause an accident.
- Observe the following additional warnings if
work on the fuel system or the electrical
system is necessary:
- Do not smoke.
- Never work near naked flames.
- Always keep an approved fire extinguisher
immediately available.
- Any work on the batteries and electrical sys­
tem in your vehicle entails a risk of injury
and chemical burns in addition to danger of
accident or fire.
For
this reason, you must
have the work carried out by
a
qualified
workshop.
© CAUTION
When topping up fluids make sure the correct
fluid is put into the correct filler opening. This
can otherwise cause serious malfunctions or
engine damage.
® For the sake of the environment
Inspect the ground underneath your vehicle
regularly so that any Leaks are detected at an
early stage. If
you
find spots of oil or other

fluids,
have your vehicle inspected in the
workshop.

Mobility
- Change clothing immediately if it becomes
soiled with the tyre sealant.
- If any allergic reactions should occur get
medical help immediately.
- Keep the sealant away from children.

©
Note
- If sealant should leak out, leave it to dry.
When it has dried, you can pull it off like a
piece of
foil.

- Observe the expiry date stated on the
seal­

ing compound can. Have the sealing com­
pound exchanged by
a
qualified workshop.
- Interference to the radio reception may oc­
cur when using the compressor*.
- Please observe the relevant regulations.

Fig.
258 Tyres: Filling the tyre
Important: The tyre repair kit must be at hand
and ready for use
•=>page
319.
Filling the tyre

•
Shake the tyre sealant can
well.

•
Screw the enclosed filling hose onto the sealant
can as far as it will go. This will automatically
pierce the foil sealing the can.
• Take the valve cap off the tyre valve and use the
enclosed valve insert tool to unscrew the valve

insert
^F/'g.
258.
• Place the valve insert onto a clean surface.
• Remove the sealing plug from the filling hose
and insert the hose into the tyre valve.
• Hold the tyre sealant can upside down and fill
the complete contents into the tyre.
• Then disconnect the filling hose and screw the
valve insert firmly back into the tyre valve.
Inflating the tyre
• Screw the compressor hose (from the tyre re­
pair kit) onto the tyre valve and plug the
con­

nector into an electrical socket in the vehicle.
• Pump the tyre up to 2.0 to 2.5 bar and monitor
the pressure shown on the pressure gauge.
• If the tyre pressure remains lower than the
val­

ue specified above, remove the hose and drive
10 metres forwards or backwards at
a
low
speed so that the sealant can spread evenly in
the tyre. Now pump the tyre up again
o
A.
A WARNING
- Please observe the manufacturers' safety
notes on the compressor and the instruc­
tions supplied with the tyre sealant can.
- If it was not possible to build up a tyre pres­
sure of 2.0 bar within six minutes this
means that the tyre is too badly damaged.
Do not drive on.
- Seek professional assistance if the repair of
a tyre puncture is not possible with the
seal­

ing compound.
© Note
Do not use the compressor for longer than
6 minutes at
a
time, as it could overheat.
When the compressor has cooled down, you
can use it again.
After repairing a tyre
Applies to: vehicles with tyre repair kit
• Affix the sticker "max. 80
km/h",
which is
inclu­

ded in the tyre repair kit, to the dashboard
where the driver will see it.
• After about 10 minutes, stop to check the tyre
pressure.
• If tyre pressure is less than 1.3 bar, the tyre is
too badly damaged. Do not drive on.
A WARNING
After repairing a tyre please note the follow-
ng points:
