HICL E OPER ATION
Driving on slopes
• If you find that you cannot climb a grade,
never try to turn. Back down the hill in re­
verse gear. If you don't. the vehicle may
tip or roll over!
• To reduce the danger of rolling the ve­
hicle, drive the vehicle as close as possible
to the "fall line" (direction of maximum
slope) -not at an angle to the fall line.
If it feels like the vehicle is about to
roll over when you are trav eling at
an angle to the fall line, turn into the
fall line immediately.
• Never park your vehicle on extreme
uphill or down hill slopes.
Deep snow
• You should promptly install wheels
equipped with winter or all-season tires
when you expect winter road conditions -
see page 260.
• Install snow chains before attempting to
drive through deep, unplowed snow - see
page 261.
200 Driving
through water
• Always make certain that the ride level
system is in the highest level before cross­
ing streams and similar water obstacles.
• You should always determine how deep
the water is before you drive through it.
• When crossing through water, travel only
at a walking speed. If possible, do not
stop and do not shut off the engine.
• Avo id driving through salt water
(beaches, for example).
After you have traveled through wa­
ter, mud or slush, your brakes may
be slow to respond due to wet brake
rotors and pads. To get back the full
braking effectiveness, apply the
brakes cautiously to dry them out­
The brakes must be dry before you
can get full brake performance. Sand,
quicksand and similar unsta­
ble soils
Cross sandy or other unstable terrain briskly
and, if possible, do not stop.

Braking
General notes
• The brakes on today's automobiles are
still subject to wear, depending largely on
operating conditions and driving habits. On
vehicles which are driven mostly in stop­
an d-go city traffic or which are driven hard,
the brake pads should be checked by your
authorized Audi Dealer more often than
specified in the Maintenance booklet.
• On steep slopes, you should use the
braking effect of the engine. This way, you
prevent unnecessary wear to the brake sys­
tem. If you must use your brakes, do not
hold the brakes down continu ously. Pump
the brakes at interv als.
• Under certain conditions, for example,
when driving through water or very heavy
rain, or even after washing your vehicle, the
braking effect can be reduced due to the
wet brake pads or pads which are iced-up in
the winter. A few cautious brake applica­
tions should dry off the brake pads or re­
move ice coati ngs. The
effect iveness of the brakes can be re­
duced when the vehicle is driven on a salt­
covered road and the brakes are not used.
Clean off accumulated salt coating from
brake discs and pads with a few cautious
brake applications.
�W ARNING
• 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, other­
wise the brake system could over­
heat reducing the effectiveness of
the entire brake aystem.
• Failure of one brake circuit will
impair the braking capability re­
sulting in an increased stopping
distance.
Avo id driving the vehicle and have
it towed to the nearest authorized
Audi Dealer or qualified work­
shop. VEH
ICLE OPERATION
Brake booster
�W ARNING
• The brake booster works with
vacuum pressure which is created
only when the engine is running.
Never let the vehicle roll to a stop
with the angina shut off.
• If the brake booster is not work­
ing, for example when towing your
vehicle, or because the brake boo­
ster has somehow been damaged,
the brake pedal must be pressed
harder to make up for the lack of
booster assistance.

HICL E OPER ATION------------------------
Functioning of Anti-Lock Brake
System (ABS)
The ABS contributes effectively to vehicle
control since it prevents the wheels from
locking when the brakes are applied. This
means that the vehicle remains steerable
and is less likely to skid.
Nota
Yo u don't have to "pump" the brake.
Just hold the brake pedal down.
However, do not expect that the ABS short­
ens braking distance under all circum­
stances. When driving on gravel or on newly
fallen snow on top of icy surfaces, braking
distance may be even longer , therefore, un­
der these circumstances, it is especially im­
portant that you drive slowly and with great
care.
202 How the
ABS system works
An automatic check is made when a speed
of about 4 mph (6 km/h) is reached.
When this happens a pumping noise can be
heard.
If an individual wheel begins to rotate too
slowly in relation to vehicle speed and tends
to lock, the ABS automatically reduces
brake pressure to prevent that wheel from
locking.
This automatic adjustment process
will cause a slight vibration of the
brake pedal and soma noises to alert
you that vehicle speed must be
adapted to existing road and traffic
conditions. Enhanced
ABS function {Offroad­
Mode)
To improve braking on loose terrain (for ex­
ample: gravel, scree, mud, slush, snow),
turn off the ESP (see page 205), which will
switch the ABS to a special mode designed
for off-road requirements.
In this mode, the ABS control system is
changed to allow a "wedge" of loose rock
or soil to form in the front of the wheels.
This improves braking performance.
The ESP indicator light in the instrument
cluster will come on when you have
switched to this special ABS mode (see
page 124).
This special ABS mode will remain active up
to about 40 mph (60 km/h). ABS operation
is not affected at speeds over 40 mph
(60 km/h).
To turn his special ABS mode off, press the
ESP button (To activate ESP, see page 152).
The ABS off-road mode will also be deacti­
vated when vou turn off the engine.

HICL E OPERA TION-----------------------
'4 WARN ING continued
• Before descending a steep
grade, reduce speed and shift
transmission into a lower gear or
lower driving position. Do not ride
the brakes or hold the pedal down
too long or too often. This could
cause the brakes to get hot and di­
minish braking efficiency.
• 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. Other­
wise the brake system could over­
heat reducing the effective ness of
the entire brake system.
• Failure of one brake circuit will
impair the braking capability re­
sulting in an increased stopping
distance.
Avoid driving the vehicle and have
it towed to the nearest Audi Dealer
or qualified workshop.
204 Electronic differential lock
(EDL)
The EDL operates in conjunction with the
ABS. The EDL acts automatically, i.e. with­
out the driver's intervention.
With the aid of the ABS sensors, this sy­
stem monitors the speed of the driven
wheels up to about 50 mph, 80 km/h .
Within the speed range at which this sy­
stem operates, if the wheels spin (e.g. on
slippery surfaces) they are braked in a con­
trolled manner , and more of the engine's
power is directed to whiche ver wheels
achieve greater traction.
Please note:
• When driving off, always be sure to keep
road conditions in mind as you accelerate.
If a drive wheel spins because it's on a slip­
perier surface, gradually increase the pres­
sure on the accelerator pedal until the car
starts to move. •
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.
• To prevent the disc brake of the braked
wheel from overheating, if subjected to ex­
cessive loads the EDL cuts out temporarily.
The vehicle remains operational and be­
haves in the same way as a vehicle without
EDL
If a fault occurs in the ABS the EDL is also
not functioning. This is ind icated by the ABS
warning light-see page 125.
ftl WARNING
The increased safety afforded by
EDL does not mean that you can
take safety risks. Always adapt
your driving style to the road con­
ditions and traffic situation.

VEHICL E
CA RE-------------------------
If the engine compartment is cleaned at any
time with grease removing solutions 1 ), or if
you have the engine washed, the antK:orr sion treatment is almost always removed
as well. It is therefore essential to ask: for a
long-lasting corrosion protection of all sur­
faces, seams, joints and components in the
engine compartment.
c£> If you must rinse off gasoline, oil
residue or grease while you are
washing your engine, then tha dirty
water should be run through an oil
separator filter. We recommend that
you have your engine washed at a
qualified workshop or service sta­
ti on.
11 Use only
the correct cleaning solutions.
Never use gasoline or Diesel.
220 Chassis
The lower body shell of your Audi is also
thoroughly protected against corrosion.
Any damage to the undercoat ing caused by
road hazards should be repaired promptly.
g WARNING
Do not apply additional undercoat­
ing or rustproofing on or near the
exhaust manifold, exhaust pipes.
catalytic converter or heat shields.
During driving, the substance
used for undercoating could over­
heat and cause a fire. Body
cavity sealing
All body cavities which could be affected by
corro sion have been given thorough protec­
tion at the factory.
This sealing does not require any inspection
or additional treatments. If any wax should
seep out of the cavity when the ambient
temperature is high, it can be removed with
a plastic scraper and a suitable solvent.
c£> If you use benzine for removing
the wax, keep sparks, flame and
ligh ted cigara ttas away. Nsver
dump benzine on the ground, into
open streams or down sewage
dr ains.
Be sure to observe all safety and en­
vi ronmental regulations.

General
notes
• We recommend that you have the engine
compartment and the underside of your ve­
hicle inspected twice a year for any damage
to the protective coating, preferably before
and after the winter season. Have neces­
sary repairs done as soon as possible.
• Also, whenever the lower body sh�ll.
axle, transmission or engine assemblies
have been repaired, any anti-corrosion coat­
ing lost on the affected surfaces should be
reapplied.
• Oil-based protective sprays must not be
applied. Only tar-or wax -based anti-corro­
sion protectors are compatible with the fac­
tory applied corrosion pro tection. Bef_ore ap­
plication, road dirt, salt spray deposits and
oily substances must be removed. Yo
ur authorized Audi Dealer stocks the
cleaning and preservation solutions recom­
mended by the factory for this purpose and
has the equipment necessary to apply
them. Therefore, any additional corrosion
protection work should be perform .ed by an
Audi Dealer. Using incorrect cleamng solu­
tions could damage rubber parts or painted
surfaces.
� WARNING
Use only the correct cleaning solu­
tions. Never use gasoline, Diesel
fuel or solvents which could cause
a fire. VE

CARE---------------------------------------------------
Maintenance
Yo ur vehicle has been designed to help
keep maintenance requirements to a mini­
mum.
However. a certa in amount of regular main­
tenance is still necessary to assure your ve­
hic le's safety, economy and reliabili ty.
c£> By regularly maintaining your
vehicle, you help make sure that
emission standards are maintai ned,
thus minimizing adverse effects on
the envir onment.
For detailed vehicle maintenance consult
your Maintenance booklet.
Under difficult operating condi­
tions, for example at extremely low out­
side temperatures, in very dusty regions,
when towing a trailer very frequently, etc.,
some service work should be performed
between the intervals specified.
This applies particularly to:
• oil changes, and
• cleaning or replacing the air filter.
228 Important
considerations for
you and your vehicle:
The increasing use of electr onics, sophisti­
cated fuel injection and emission control
systems, and the generally increasing tech­
nical complexity of today's automobiles,
have steadily reduced the scope of mainte­
nance and repairs which can be carried out
by vehicle owners. Also, safety and en­
vironmental concerns place very strict
limi ts on the nature of repairs and adjust­
ments to engine and transmission parts
which an owner can perform . Main
tenance, adjustments and repairs usu­
ally require special tools, testing devices
and other equipment available to specially
trained workshop personnel in order to as­
sure proper performance, reliability and
safety of the vehicle and its many systems.
Impr oper maintenan ce, adjustments and
repairs can impair the operation and reliabil­
ity of your vehicle and even void your ve­
hicle 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 ad­
versely affected, creating unnecessary
risks for you and your passengers.

Engine oil
Specification and viscosity
Yo ur engine was factory filled with an all
season high quality engine oil. If you need to
add oil between oil changes, use any high
quality petroleum- or synthetic-based oil
with correct specifications.
The following terms must appear on the oil
conta iner singly or in combination with oth­
er designations:
- API Service SJ
- ACEA A2 or ACEA A3
Engine oils are graded according to their vis­
cosity. The proper grade to be used in your
engine depends on existing climatic or sea­
sonal conditions.
The engine oil which was first put into your
engine has a viscosity grade of SAE OW--30.
You can use this oil over all temperature
ranges for normal driving. If engine oil vis­
costy grade SAE OW--30 is not available, you
can also use SAE 5W-30 or SAE 5W-40.
See your authorized Audi Dealer tor more in­
formation regarding oil for your vehicle.

Engine oil identification symbol
Oils of the proper qualityforyour vehicle will
be identified with a new "starburst" sym­
bol A. The starburst symbol indicates that
the oil has been certified by the American
Petr oleum Institute (API). Another
oil identi fication symbol B could be
added to the oil container to help you select
the correct oil.
1 - The top portion indicates the oil quality
by API designations.
2 - The center portion shows the SAE oil
viscosity grade.
3- The lower portion indicates that the oil
has fuel saving capabilities.
Note
Look for one of these symbols on the
front of the oil container. and use
only oils that display these symbols.
Engine oil additives
Audi does not recommend the use of
oil additives. They may adversely af­
fect your New Vehicle Warranty.
