engine oil AUDI ALLROAD 2000 Owner's Manual

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.

Adding engine oil
A Always heed all WA RNINGS
r!!J on page 232.
• Turn off the engine.
• Unscrew the oil cap from the cylinder
head cover.
• Add oil by a half quart (half liter) at a time.
• Check the oil level with the dipstick.
:236 The
oil level must never be above the
"a .. range.
Otherwise oil could be drawn into the crank­
case breather and get into the atmosphere
through the exhaust system. The oil
would bum then In the catalytic con­
verter and cause damage.
� WARNING
Spilled oil is a fire hazard. The oil
filler cap must be secure to avoid
an oil spill.
• Carefully screw the oil cap back on and in­
sert the oil dipstick all the way. Otherwise
oil could leak out when the engine is run­
ning. Changing
the engine oil
The engine oil must be changed according
to the intervals specified in your Mainte­
nance booklet.
This is very important because the lubricat­
ing properties of oil diminish gradually dur­
ing normal vehicle use.
Under some circumstances the engine oil
should be changed more frequently.
Change oil more often if you drive mostly
short distances, operate the vehicle in dusty
areas or under predominantly stop-and-go
traffic conditions, or have your vehicle
where temperatures remain below freezing
for exte nded periods.
Detergent additives in the oil will make
fresh oil look dark after the engine has been
running for a short time. This is normal and
is not a reason to change the oil more often
than recommended.

---------------------------------------------------VEHICLE CA
RE
�W ARNING
• If you must change the engine
oil in your vehicle:
• Wear eye protection.
• To reduce the risk of burns from
hot engine oil let the engine cool
down to the touch.
• When removing the oil drain
plug with your fingers, stay as far
away as possible. Always keep
your forearm parallel to the
ground to help prevent hot oil
from running down your arm.
• Drain the oil into a container de�
signed for this purpose, one large
enough to hold at least the total
amount of oil in your engine. ,A
WARNING continued
• Engine oil is poisonous. Keep it
well out of the reach of children.
• Continuous contact with used
engine oil is harmful to your skin.
Always protect your skin by wash­
ing thoroughly with soap and wa­
ter. �
BefoN changing your oil, first
make sure you know where you
can properly dispose of the old oil.
Always dispose of used engine oil
proper ly. Do not dump it on garden
soil, wooded areas, Into open
streams or down sewage drains.
Recycle used engine oi l by taking it
to a used engine oil collection facil­
ity in your area, or contact a service
station.
Because of the problem of proper
disposal, along with the special
tools and necessary expertise re­
quired, we strongly recommend that
you have your oil changed by an au­
thorized Audi Dealer or a qualified
workshop.

Engine cooling system
The cooling system is sealed and generally
requires little attention.
The cooling system has been filled at the
factory with a permanent coolant which
does not need to be changed. The coolant
consists of a mixture of water and the
man ufacturer's coolant additive G 12 ABD
-ant ifreeze on a glycol base with anti-corro­
sion additives (50% for USA models; 60o/o
for Canadian models). This mixture assures
the necessary frost protection and protects
alloy components in the engine's cooling
system from corrosion and scaling. It also
raises the boiling point of the coolant.
Do not reduce the concentration of the cool­
ant in the summer by adding plain water.
The proportion of coolant additive
must be at least 500fa but not more
than 600fa to maintain antifreeze protec­
tion and cooling efficiency.
238 For
year-r ound driving, antifreeze is added at
the factory for temperatures down to:
-31 °F (-35 °C) USA
-40 °F (-40 °C) Canada.
g Always heed all WA RNINGS
E!!1 on page 232.
Never use eny coolant additive
other than our G12 ABD additive
(check label) for your vehicle. This
coolant additive is available at au­
thorized Audi Dealers.
Other types of antifreeze can. above
all. significantly reduce corrosion
protection. The resulting corrosion
can cause a loss of coolant and
therefore serious engine damage. When
adding coolant additive to
your cooling system. please remem­
ber:
Under no circumstances may G12
ABD be mixed with other coolant ad­
ditives (for example G 11 ).
You can recognize G12 ABD in the
expansion tank by its red color. If
the liquid in the expansion tank is
brown, G 12 ABD has been mixed
with another coolant additive. In
this case. your vehicle's coolant
must be changed as soon as pos­
sible.
Note
Mixing coolant additives can result
in serious malfunction or engine
damage!

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.

When disconnecting and
connecting the battery ...
When you disconnect the vehicle battery
please note the following:
- some data stored in the driver informa-
tion system are erased,
- the clock goes out,
- the factory installed radio locks up,
- the Engine management system,
- the one-touch-u p and one-touch-down
functions of the power windows no lon­
ger work,
- all stored seat positions in the memory*
are erased.
Af teryou reconnect the battery, you must
reset the clock. � page 118.
You also have to reset the Engine manage­
ment system -see "Starter Switch "
�pa ge 113.
You also have to reset the one-touch-up and
one-touch�down feature on power win­
dows -see "Power windows "
�p age 71.
248 You
have also reset the seat memory* -see
"Seats"
� page 81.
The radio must be re-coded with the correct
radio code - see your radio Operating In­
structions.
Replacement battery
A replacement battery must have the same
specifications and dimensions as the origi­
nal equipment battery. Specifications are
listed on the battery housing.
When installing the battery, make sure the
ignition and all electrical consumers are
switched off.
r.Gb. Because of the problem of �proper di
sposal of a battery, we
recommend that you have your au­
thorized Audi Dealer change the
battery for you. Batteries contain
sulfuric acid and lead and must al­
ways be disp osed of properly ob­
serving all environmental regula­
tions. Air
cleaner
A dir ty air cleaner element not only reduces
the engine output and increases fuel con­
sumption considerably but can also cause
premature engine wear.
Normally, it is not necessary to service the
air cleaner more often than recommended
in the Maintenance booklet. If the vehicle is
driven on very dusty roads, the air cleaner
must be serviced more frequently, even dai­
ly.
If your air cleaner element must be
changed mora frequently, we rec­
ommend that you have the air clean­
er serviced by your authorized Audi
Dealer or a qualified workshop.
The air cleaner element must never
be cleaned or soaked with gasoline,
cleaning solvents or oil.

Lifting
vehicle
Lifting with workshop hoist
and with floor jack
Notes
• The vehicle should never be lifted
or jacked up from underneath the
engine oil pan, the transmission
housing, the front or rear axle or the
body side members. This could lead
to serious damage.
The same lifting points as illus trated on the
next page for the hoist also apply when a
floor jack is used.
e To avoid damage to the under­
body or chassis frame, it is neces­
sary to insert a rubber pad between
the floor jack and the lift points.
• To prevent damaging the shock
absorbers when lifting the vehicle
with a jack or on a hoist, the level
selection must be in the jack mode.
See next page. �W
ARNING
• To reduce the risk of serious in­
jury and vehicle damage, lift the
vehicle only at the special work­
shop hoist and floor jack lift points
illus trated. Failure to lift the ve­
hicle at these points could cause
the vehicle to tilt or fall from a lift
if there is a change in vehicle
weight distribution and balance.
This might happen, for example,
when heavy components such as
the engine block or transmission
are removed.
• When removing such heavy
components, anchor vehicle to
hoist or add correspo nding
weights to maintain the center of
gravity. Otherwise, the vehicle
might tilt or slip oH the hoist,
causing serious damage or person­
al injur y. DO-IT-YOU
RSELF SERVICE
�� WARNING continued
• If you must lift your vehicle with
a floor jack to work underneath,
be sure the vehicle is safely sup­
ported on stands intended for this
purpose.
• Before driving over a workshop
hoist, check that the vehicle weight
does not exceed the permissible lift­
ing capacity of the hoist.
• Before driving over a workshop
hoist, ensure that there is suHicient
clearance between the hoist and
low parts of the vehicle.
