�W ARNING
• Before working in the engine
compartment. be sure to read the
information on page 232.

possibly causing personal injury
from the moving wiper linkage.
• Do not wash. wax or dry the en�
gine with the engine ru!'l'! ing. Mov­
ing or hot parts could 1n1ure you. ,Al
WARNING continued
e Do not clean the underside of
the chassis, fenders. wheel cov­
ers. or other hard to reach parts
without protecting your hands and
arms. You may cut yourself on
sharp-edged metal parts.
• Moisture and ice on brakes may
affect braking efficiency. Test the
brakes carefully after each vehicle
wash.
The engine compartment and transmission
have been corrosion protected at the facto­
ry.
Remove leaves from the plenum panel in
front of the windshield under the engine
hood. This prevents the water drain holes
from becoming blocked, and it prevents de­
bris from entering the vehicle interior
throug h the heating and ventilation ducts. Good
anti-corrosion treatment is very im­
porta nt, particularly in the winter. If the ve­
hicle is frequently driven on salted roads,
the entire engine compartment and plenum
panel should be thor oughly cleaned at the
end of winter and retreated to prevent salt
damage. At the same time, the underside of
the vehicle should be washed as well.
�W ARNING
Never touch the radiator fan. The
auxiliary electric fan can switch on
suddenly and injure you-
Always switch off the ignition be­
fore cleaning the engine _

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.
