Breaking in
New engine
The engine needs to be run-in during the first
1,000 miles (1,500 km).
For the first 600 miles (1,000 kilometers):
.,. Do not use full throttle .
.,. Do not drive at engine speeds that are more
than 2/3 of the maximum permitted RPM .
.,. Avo id high engine speeds.
From 600 to 1,000 miles (1,000 to 1,500
kilometers):
.,. Speeds can gradually be increased to the maxi­
mum perm issib le road or engine speed.
During and after break-in period
.,. Do not rev the engine up to high speeds when it
is cold . This applies whether the transmission is
i n N (Neutral) or in gear .
After the break-in period
.,. Do not exceed maximum engine speed under
any circumstances.
.,. Upshift into the next higher gear
before reach­
i ng the red area at the end of the tachometer
scale~
page 10 .
During the first few hours of driving, the engine's
internal friction is higher than later when all the
mov ing parts have been broken in. How well this
break- in process is done depends to a considera­
b le extent on the way the vehicle is d riven during
the first 1,000 miles (1,500 kilometers).
(D Note
Extremely high engine speeds are automati­
cally reduced. However, these rpm lim its are
programmed for an engine we ll run-in, not a
new engine .
188
® For the sake of the environment
Do not drive with unnecessarily high engine
speeds -upshifting early saves fuel, reduces
noise and protects the environment.
New tires
If your vehicle is running on new tires, drive par­
ticularly careful for the first 350 m iles (500 kilo­
meters) after f itting .
.8, WARNING
New tires tend to be slippe ry and must also
be "broken-in". Be sure to remember this dur­
ing the first 350 mi les (500 kilometers).
Brake gent ly. Avoid following closely behind
other ve hicles or other situations that might
require sudden, hard braking.
Avoid damaging the
vehicle
When you are driving on poor roads, or over
curbs, steep ramps, etc., make certain that low­
lying parts such as spo ilers and exhaust system
parts do not bottom out and get damaged .
-
This is especially true for vehicles with low-slung
chassis (sports chassis)* and fully loaded
vehicles.
Driving through water on
roads
Note the following to avoid vehicle damage when
driving through water, for examp le on flooded
roads:
- The water must not be any highe r than the bot­
tom of the vehicle body.
- Do not drive faster than walk ing speed .
.8, WARNING
After driving through water or mud, the brak­
ing effect can be red uced due to moisture on
the brake discs and brake pads . A few careful
brake applications should dry off the brakes.

CD Note
-Vehicle components such as the engine,
transm ission, suspension or electrical sys­
tem can be severely damaged by driving
through water.
- Determine the depth before driv ing through
water.
- Do not stop the vehicle, drive in reverse or
switch the eng ine off when dr iving through
water.
- Keep in mind that oncoming veh icles may
create waves that raise the water level and
make it too deep for your vehicle to drive
through safely .
- Avo id d riving through salt water (corrosion).
Warming up and cooling
down
By carefully warm ing up and cool ing down your
veh icle, you can he lp ensure that it is not over­
stressed un necessa rily during sporty driving.
When warming up, the vehicle is dr iven at a max­
i mum eng ine speed of 6000 RPM in order to raise
the eng ine oi l temperature to a min imum of
140 °F (60 °C). The tires a lso on ly reac h their f ull
road ho ld ing capability once they have warmed
up .
The cooling fan can continue to run in your vehi­ cle after the engine is swi tched off. Howeve r,
d riving the vehicle to cool it dow n is particularly
important. D uring sporty dr iv ing, the engine and
brakes, the exhaust system, and the transmission
a ll become extremely hot. Before you park the
ve hicle, you shou ld drive it for a few m iles/kilo­
meters at light load in the low rpm range to al­
low it to cool down.
Driving and the envir onment
Catalytic converter
Applies to: veh icles w ith gasoli ne e ngi ne
It is very important that your emission control
system (catalytic converter) is functioning prop­
erly to ensure that your vehicle is running in an
environmentally sound manner .
.. Always use lead-free gasoline¢ page 198,
Fuel supply.
.. Never run the tank down all the way to empty.
.. Never put too much motor o il in yo ur engine
¢ page 20 7, Adding engine oil 9:::r. .
.,. Never try to pus h- or tow-start your veh icle.
The catalytic co nverter is an efficient "clean-up"
device built into the exhaust sys tem of t he ve hi­
cle. The catalyt ic conv erter b urns ma ny of the
po llutants in the exhaust gas before they are re­
leased into the atmosphere.
The exclusive use of un leaded fuel is cr itically im­
po rtant fo r the life of the catalytic converte r and
prope r fu nct io ni ng of the eng ine.
_&. WARNING
The tempe ra tu re o f th e exh aus t sys tem is
hi gh, bot h when driv ing and a fter stopping
the engine.
- Never tou ch the e xhaus t tail pipes on ce they
have become hot. This cou ld res ult in burns.
- Do not p ark or operate the vehicle in ar eas
where the hot exhaus t sys tem may come in
contact w ith dry grass, b rush, fuel spill or
other mate rial which can ca use a fire.
- Do not app ly additiona l undercoating or
r u stp roofing on or near the exhaust mani­
fold, exha ust pipes, cata lytic converter or
heat shields. D uring driving, the substance
used for undercoat ing could overheat and
cause a fire.
CD Note
- Be aware that just one tank fi lling with
leaded fuel w ill already seriously degrade
the performance of the catalytic converter.
- Do not exceed the correct engine oil leve l
¢page 207.
189

Driving and th e en vironm ent
- Do not drive until the fuel tank becomes
complete ly empty . The engine cou ld mis­
fire . Unburned fuel could also get into the
exhaust system and this cou ld cause the
catalytic converter to overheat.
- Do not sw itch off the ignition while the vehi­
cle is moving.
- Do not continue to operate your vehicle un­
der these cond itions, as otherwise fuel can
reach the catalytic converter. This could re­
sult in overheating of the converter, requ ir­
i ng its replacement.
- To assure efficient operation of the Emis­
sion Control System :
- Have your veh icle maintained properly and
in accordance with the service recommen ­
dations in your Warranty
& Maintenance
book let.
- Lack of proper maintenance as well as im ­
proper use of the vehicle will impair the
function of the emission control system and could lead to damage.
@ For the sake of the environment
Even when the Emission Control System is op­
erating properly, the exhaust gas can have a
sulfur-like exhaust gas smell under some op­
erating states. This depends on the sulfur
content of the fuel be ing used . Using a differ­
ent brand of fuel may help, or filling the tank
w ith lead-free super grade gasoline.
Placing your vehicle out
of service
If you would like to take your vehicle out of serv­
ice for a longer time, contact your authorized
Audi dealer or authorized Audi Service Facility.
They will advise you of important measures, such
as corrosion protection, maintenance and stor­
age procedures. Also follow the information
about the battery

Economical and environ­
mentally-friendly driving
General
Your personal style of driving will determine the
economy of your vehicle, as well as exhaust and
noise levels.
Fuel economy, env ironmental impact, and wear
on your engine, brakes and tires large ly depend
on three factors:
- your personal driving style
- operating conditions
- technical limitations
If you anticipate what you need to do next and
drive economically, you can easily cut your fuel
consumption by 10-15 percent. This section will
give you some tips on how you can help the envi­
ronment and your pocketbook.
(j) Tips
The consumption estimates as published by
ENVIRONMENTAL PROTECTION AGENCY
(EPA) and Transport Canada may not corre­
spond to your actual consumption on the road, which will vary depending upon vehicle
l oad and speed, road and weather conditions,
trip length, etc.
Drive smoothly and keep a lookout ahead
Vehicles use the most fuel when they are acceler­
ating.
~ Avoid unnecessary accelerat ing and braking .
Vehicles use the most fuel when they are acceler­ ating. If you anticipate what is going to happen
next, you will need to brake less and, thus, accel­
erate less . Let the vehicle coast whenever possi­
ble -for example when you see that the next traf­
fic light is red.

,&_ WARNING
-The cooling system is under pressure and
can get very hot. Reduce the risk of scalding
from hot coolant by following these steps.
- Turn off the engine and allow it to cool
down.
- Protect your face, hands and arms from
escaping fluid and steam by covering the
cap with a large, thick rag.
- Turn the cap slowly and very carefully in a
counter-clockwise direction while applying light, downward pressure on the top of
the cap.
- To avoid being burned, do not spill ant i­
freeze or coolant on the exhaust system or
hot engine parts. Under certa in condi­
tions, the ethylene glycol in engine cool­
ant can catch fire.
- Antifreeze is poisonous. Always store anti­
freeze in its original container and well out
of the reach of children.
- If you drain the coolant, it must be caught
and safely stored in a proper container
clearly marked "poison" .
(D Note
-Do not add coolant if the expansion tank is
empty. Air could enter the cooling system
and damage the eng ine. If this is the case,
do not continue driving. Seek professional
assistance.
- Coolant pollutes the environment and could
cause an engine fire. Excess coolant will be
forced out through the pressure relief valve
i n the cap when the engine becomes hot .
- If, in an emergency, only water can be add­ ed, the correct ratio between water and an­
tifreeze
¢ page 209 must be restored as
soon as possible.
@ For the sake of the environment
Drained coolant should not be reused. Always
dispose of used coolant while observing all
environmental regulat ions.
-
Checking and Filling
Radiator fan
The radiator fan switches on automatically by it­
self .
An auxiliary electric radiator fan switches on and
off depending on coolant temperature and other
vehicle operating conditions.
After you switch the engine off, the auxiliary fan
can continue running for up to 10 minutes -even
with the ignition off. It can even switch on again later by itself ¢&. , if
- the temperature of the engine coolant rises due
to the heat build-up from the engine in the en­ gine compartment, or
- the engine compartment heats up because the
vehicle is parked in intense sunlight.
A WARNING
--
- To reduce the risk of personal injury never
touch the radiator fan .
- The auxiliary electric fan is temperature
controlled and can switch on suddenly even
when the engine is not running .
- The auxiliary radiator fan switches on auto­
matically when the engine coolant reaches a
certa in temperature and will continue to run
until the coolant temperature drops.
Brake fluid

Before you check anything in the engine compart­
ment,
always read and heed all WARNINGS
¢ & in Working in the engine compartment on

211

Checking and Filling
"' Read the brake fluid level from the brake fluid
reservoir
¢ fig. 187, ¢page 205, fig. 183. The
brake fluid level must be between the "MIN"
and "MAX" markings.
The location of the brake fluid reservoir can be
seen in the engine compartment illustration
c>page205.
The fluid level may drop slightly after some time
due to the automatic adjustment of the brake
pads. This is not cause for alarm.
If the brake fluid level falls considerably below
the "MIN" mark, the brake warning/indicator
light
1111 (U.S. models)/ . (Canadian models)
will come on¢
page 14. Do not continue to oper­
ate the vehicle. The complete brake system
should be thoroughly checked by an authorized
Audi dealer or other qualified facility and the
cause corrected . If the brake fluid level is too
low, the brake warning/indicator light will illumi­
nate. Contact an authorized Audi dealer
immedi­
ately.
Changing brake fluid
Have the brake fluid changed by an experienced
technician.
Brake fluid absorbs moisture from the air . If the
water content in the brake fluid is too high , cor­
rosion in the brake system may result after a pe­
riod of time. The boiling point of the brake fluid
will also decrease considerably and decrease
braking performance.
Therefore, the brake fluid must be changed
every
two years.
Always use new brake fluid which con­
forms to Federal Motor Vehicle Standard "FMVSS
116 DOT 4".
The brake fluid reservoir can be difficult to reach,
therefore, we recommend that you have the
brake fluid changed by your authorized
Audi
dealer.
Your dealer has the correct tools, the
right brake fluid and the know-how to do this for
you.
212
A WARNING
-
- Brake fluid is poisonous. It must be stored
only in the closed original container out of
the reach of children!
- Brake failure can result from old or inappro­
priate brake fluid. Observe these precau­
tions:
- Use only brake fluid that meets SAE speci­
fication
J 1703 and conforms to Federal
Motor Vehicle Standard 116. Always check
with your authorized Audi dealer to make
sure you are using the correct brake fluid.
The correct type of brake fluid is also indi­
cated on the brake fluid reservoir .
- The brake fluid must be new. Heavy use of
the brakes can cause a vapor lock if the
brake fluid is left in the system too long .
This can seriously affect the efficiency of
the brakes as well as your safety. This
could result in an accident.
(D Note
Brake fluid will damage the paint of your vehi­
cle.
@ For the sake of the environment
Because of the problem of proper disposal of
brake fluid as well as the special tools re­
quired and the necessary expertise, we rec­
ommend that you have the brake fluid
changed by your authorized Audi dealer .
Battery
General information
Under normal operating conditions, the battery
in your Audi does not need any maintenance.
With
high outside temperatures or long daily
drives we recommend that you have the electro­
lyte level checked by a service facility. The elec­
trolyte level should also be checked each time
the battery is charged ¢
page 214.
Have the battery checked when you take your ve­
hicle in for service. You are well advised to re­
place a battery that is older than S years.
