VE
HICLE OPERATION------------------------
The external conditions
in which you drive also affect your fuel con­
sumption.
The following conditions increase fuel con­
sumption:
• Heavy traffic, especially in large cities
with many traffic lights.
• Stop-and-go driving, especially short dis­
tances so that the engine never warms up
as it should.
• Driving in heavy, slow moving traffic in
low gear so that the engine speed is rela­
tively high when compared to the distance
driven.
� Plan your trips ahaad of time. Or­
� ganizs your trips to include sev­
sral errands and to avoid heavy traf­
fi c.
Of course, there are some conditions that
will affect fuel consumption that you can't
control.
For example, fuel consumption increases in
the winter or under difficult conditions (bad
roads, towing a trailer, etc.).
19 6 The
technical requirements
for optimum fuel consumption and eco­
nomy were ''built" intoyourvehicle. Special
attention was paid to the environment. To
reta in and make use of these characteris­
tics, please note the following points:
riJ Use only unleaded gasoline.
Leaded gasoline causes damage to the cat­
alytic converter and other components of
the emission system.
t:Gh Have your vehicle serviced by an
� Audi Dealar at the specified in­
tervals -see page 228 and your
Main tenance booklet.
Having your vehicle regularly serviced by an
Audi Dealer helps ensure that it runs prop­
erly and economical ly, that it does not dis­
turb the environment, and that it has a long
service life. t:Gh
Check
your tire pressure once a
W month.
Low tire pressure increases fuel consump­
tion and tire wear, and impair s vehicle han­
dling.
�W ARNING
Underinflation and overloading of
tires can lead to tire failure. Sud­
den failur e on the road could cause
a serious or fata l accident. See
page 253 for inflation informa­
tion.
� Do not carry unnecessary items
in the luggage compartment.
Particularly in city traffic where you must
often accelerate, weight influences fuel
consumption.

VE
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.

Engine
hood
To unlock the engine hood, pull the re­
lease lever on the left under the dashboard.
The hood pops up slightly under spring pres­
sure.
Note
Before opening the engine hood,
make sure that the windshield wip­
ers are folded flat against the wind­
shield. Otherwise, they could dam­
age the paint on the hood. To
open, pull the release lever in the direc­
tion indicated by the arrow. This will release
the hook under the hood.
Open the hood all the way. It will be held up
by gas pressure in the strut. VEH
ICLE CARE
To close
Pull the hood down until the pressure from
the strut is reduced. Then Jet the hood fall
and latch in place -you do not need to
press the hood down again.
m WARNING
• A hood that is not 'completely
latched could fly up and block
your view while driving. When you
close the engine hood, check it to
make sure the safety catch has
properly engaged. The hood
should be flush with the surround­
ing vehicle body parts.
• If you ever notice while driving
that the hood is not secured prop­
erly, stop at once and close it.
Always heed all WA RNINGS
on next page.

Engine
oil consumption
The rate of the oil consumption depends on
the quality and viscosity of oil, the speed at
which the engine is operated, the climate,
and road conditions as well as amount of
dilution and oxidation of the lubricant.
Because of these variables, no standard
rate of oil consumption can be established,
but drivers should expect higher oil con­
sumption at high speeds and when the en­
gine is new.
Therefore, we recommend that you check
the oil level at regular intervals (for example,
each time you are refuelling, or before going
on a long trip).
If the oil level should go below the minimal
level, the check engine oil level warn­
ing light* in the instrument cluster will
come on. See page 144. You should check
the oil level using the oil dip stick as soon as
possible, and then top off the oil as neces­
sary. Notes
• The engine in your vehicle de­
pends on oil to lubricate and cool all
of its moving parts. Therefore the
engine oil should be checked regu­
larly and kept at the required level.
• Lack of sufficient engine oil may
lead to severe engine damage.
• The oil pressure warning light is
not an oil level indicator.
A Always
heed all WAR NINGS
� on page 232.
Checking the engine oil level
The best time to check the engine oil level
is when the oil is warm.
To get a true reading, the vehicle must be on
level ground.
A Always heed all WAR NINGS
� on page 232.
• After turning off the engine, wait a few
minu tes for the oil to return to the oil pan. VE
HICLE CARE
• Pull out dipstick (arrow) and wipe it clean
with a rag.
• Reinsert dipstick; push it all the way in.
• Pull dipstick out again and read the level:
a - Yo u must not add oil.
b- You can add oil. The oil level may go
into the a range, but riot above the a
range
c - You must add oil.
After filling in oil, make sure that the oil
level is somewhere within the b range.
• After checking the oil level, please make
sure that the dipstick is pushed back in all
the way.
235

Checking the
engine coolant
level
The coolant expansion tank is located on the
left of the engine compartment -see il­
lustration.
The coolant level is automatically monitored
by the Auto-Check System -see page 141.
However, it is still recommended to check
the coolant lev�l visually from time to time
and always before going on a longer trip.
�W ARNING
To reduce the risk of being burned.
never open the hood if you see or
hear steam or coolant escaping
from the engine compartment.
Wait until no steam or coolant can
be seen or heard before carefully
opening the hood and following
the precautions on the next page.
Always heed all WA RNINGS
on page 232. To
obtain an accurate reading, the engine
must be switched off.
Since the expa nsion tank is transparent, the
cap need not be removed to check the cool­
ant level.
The coolant level must be between the
"MIN" and "MAX" marks when the en­
gine is cold and can be slig htly above the
"MAX" mark if the engine is warm. VE
HICLE CARE
The expansion tank in your vehicle is
equipped with an electric coolant level
checking device.
When the coolant level is too low, the warn­
ing light (see page 141) in the Auto-Check
System will blink until you add coolant and
the coolant level has been restored to nor­
mal.
Coolant losses
Coolant losses may indicate a leak in the
cooling system. In the event of coolant
losses, the cooling system should be in­
spected immediately by your authorized
Audi Dealer. It is not enough merely to add
coolant.
In a sealed system, losses can occur only if
the boiling point of the coolant is exceeded
as a result of overheating.

Brake fluid
The brake fluid reservo ir is located on the
left of the plenum chamber at the back of
the engine compartm ent.
242 Checking
brake fluid level
The correct fluid level is important for the
proper functioning of the brake system. The
fluid level in the brake fluid reservoir should
always be between the "MAX" and
"MIN" markings.
The fluid level may drop slightly after some
time due to the automatic adjustment of the
brake pads. This is no cause for alarm.
• If the brake fluid level falls con­
siderably below the "MIN"
mark, the brake warning light will
coma on. Do not continue to operate
the vehicle. The complete brake sys­
tem should be thoroughly checked
by an authorized Audi Dealer or
another qualified workshop and the
cause corrected.
The brake warning lamp lights up to indicate
a low fluid level in the reservoir.
For more details see "Warning I Ind icator
lights," page 126.
Contact an authorized Audi Dealer
immediately. Changing
brake fluid
The brake fluid reservoir can be dif­
ficult to reach, therefore, we recom­
mend that you have the brake fluid
changed by your authorized Audi
Dealer. Your dealer has the correct
tools and know-how to do this for
you.
Brake fluid absorbs moisture from the air. If
the water content in the brake fluid is too
high, corrosion in the brake system may re­
sult after a period of time. The boiling point
of the brake fluid will also decrease consid­
erably.

-------------------------VEHICL E CA RE
Do not disconnect the vehicle bat­
tery when the ignition is switched
on or when the engine is running.
Otherwise, you will damage elec­
tronic components in the electrical
system.
When working on the engine, pro­
tect the battery housing from ultra
violet (UV) rays by not parking the
vehicle in direct sunlight. Winter
operation
During the winter months, battery capacity
tends to decrease as temperatures drop.
More power is also consumed while start­
ing, and the headli ghts, rear window defog­
ger, etc., are used more often.
Av oid unne cessary power consumption,
particularly in city traffic or when trave:ling
only short distances. Let your authonzed
Audi Dealer check the capacity of the ve­
hicle battery before winter sets in. A well
charged battery will not only prevent start­
ing problems but will also last longer.
If your vehicle is left standing for
several weeks at extremely low tem­
peratures, the vehicle battery
should be removed and stored
where it will not freeze. This will
prevent it from being damaged. Location
of vehicle battery
g Always heed all WAR NINGS
� on page 232.
The vehicle battery is located under a cover
in the plenum chamber at the back of the
engine compartment. To remove the cover,
press the straps (arrows ), swing up and re­
move.
