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 surrounding vehicle body parts.

Working in the engine compartment
Be especially careful whenever you work in the engine
compartment.
Whenever you must perform any work in the engine compartment,
for example checking and filling different fluids, there is a risk of
injury, burns and accidents. To prevent personal injury always

• Move selector lever of automatic transmission to "P" (Park).
• Always let the engine cool down. Hot components will burn
skin on contact.
• To reduce the risk of being burned, never open the hood if you
see or hear steam or coolant escaping from the engine compart­
ment. Wait until no steam or coolant can be seen or heard before
carefully opening the hood.

Driv ing with an i nsufficient o il level is likely to cause severe damage
to the engine .
[I) Tips
• The oil pressure warning display 'e:r. is not an ind icator of the oil
level. Do not rely on it . Instead, check the oil level in your engine at
regular intervals, preferably each time you refuel, and always
before going on a long trip.
• If you have the impression your eng ine consumes excessive
amo unts of o il, we re commen d that yo u cons ult an aut ho riz ed Aud i
dealer to have the cause of your concern properly diagnosed . Keep in
m ind th at the accurate measure ment o f oil consumption re quires
great care and may take some time. An author ized Audi dealer has
ins truc tions about how to meas ure o il consumption acc ura tely .•

• Before reconnecting the battery, make sure all electrical
consumers are switched off. Reconnect the positive cable first and
then the negative cable. Never interchange the cables -this could
start a fire!
• Never charge a frozen or a thawed-out battery. It could
explode! If a battery has frozen, then it must be replaced. A
discharged battery can freeze over at 32°F (0°C).
• Make sure the vent hose is always attached to the opening on
the side of the battery.
• Never use batteries which are damaged. There is the danger of
an explosion! Always replace a damaged battery.

Allow a froze n battery to thaw comp lete ly before attempt ing to
charge it~ & . H owever, we recommend not using a thawed batte ry
again because the battery casing can be c rack ed d ue to ice format ion
and can lea k battery acid.
Battery charging (Maximum charging rate of 30
amps/14.8 Volt)
Wh en charging a t /ow voltages (e.g. with a trickle charger), t h e
battery cables do not have to be disconnected first. The battery caps
should not be opened w hen c ha rging a ba ttery.
It is not necessary to remove the battery from the luggage compart ­
me nt.
Fast charging the battery (charging rate above 14.8
Volts)
For technical reasons do not use a battery cha rger that uses voltage
grea ter than 14.8 Vol ts to cha rge yo ur vehicle's batte ry.
& WARNING
Charging a battery can be dangerous .
• Always follow the operating instructions provided by the
battery charger manufacturer when charging your battery .
• Never charge a frozen battery . It may explode because of gas
trapped in the ice. Allow a frozen battery to thaw out first.
& WARNING (c on tinued )
• Do not reuse batteries which were frozen. The battery housing
may have cracked and weakened when the battery froze.
• Charge the battery in a well ventilated area. Keep away from
open flame or electr ical spark . Do not smoke . Hydrogen gas gener­
