tion switched on. The fuel gauge may
ot herwise not ind icate the correct fue l
level after ref uell ing .

178 Checking and filling
Ai r bubbles in the window can cause an inac­
curate reading. Carefully tap on the side of
the w indow.
- If the window is gr ee n, the battery ac id leve l
is correct.
- If the window has no c olo r or is brigh t yel­
low ,
the battery acid leve l is too low . Have
the battery tested by your authorized A udi
dealer or a qualified workshop .
- If the window is
black , then the batte ry is
insufficiently charged. Recharge the battery
as soon as possible ¢

Do not overfill the battery, otherwise bat­
tery acid will overflow through the vent
opening. This can damage the paint and
cause corros ion.
Charging of battery
Starting the engine requires a well charged
battery.

low ¢
A and ¢ A in Working on the bat­
tery on page 176.
• Switch off the ignit ion and all electrical con­
sumers.
• Make sure the area is well vent ilated when
you charge the battery .
• Connect charger cables.

• Switch on the charger .
•T urnoff the charger ¢,& .
• Disconnect the charger cables.
• Connect both battery cables to the battery if
necessary-
first plus, then m inus.
When charging at
low voltages (e.g . with a
tri ckle char ger), the battery cables do not
have to be d isconnected first. Before charging
at
high voltages, i.e. "fa st charg ing ", you
must disconnect both cables. In e ither case,
follow the instruct ions from the manufacturer
of the charger. Fastcharging a battery is
dangerou
s ¢.&. in
Working on the battery on page 176 .
It re­
quires special charging equipment and the
knowledge to go with it. We recommend hav­
ing your battery fast charged only by a quali­
fied workshop .
A d ischarged battery can
freeze at tempera ­
tures of only
32 °F (0 °C). Allow a frozen bat­
tery to thaw completely before attempting to
charge it¢,&.. However, we recommend not
us ing a thawed battery aga in because the bat­
tery casing can be cracked due to ice fo rma­
t ion and can leak battery acid.
Do not open the battery caps when charging
the battery .
A WARNING ,..__ -
Charging a battery can be dangerous.
- Never charge a frozen battery . It may ex­
p lode because of gas trapped in the ice .
Allow a frozen battery to thaw out first.
- Do not reuse batteries wh ich were fro­
zen. The battery hous ing may have
cracked and weakened when the battery
fro ze.
- Cha rge t he battery in a well venti lated
area. Keep away from open flame or elec­
tr ica l spar k. Do not smo ke. Hyd rogen gas
genera ted by the battery is explos ive .
- To reduce the danger of explosion, never
connect or d isconnect charger cab les
while the charger is operating.
- Fast charging a ba ttery is dange rous and
should only be at tempted by a compe­
tent technician with the proper equip­
ment.
- Battery acid tha t may sp ill dur ing cha rg ­
ing should be washed off with a solution
of warm water and baking soda to neu­
tralize the ac id.
(D Note
Neve r use a fast charger as a booster to
start the engine. This wi ll seriously dam­
age sensit ive e lectronic components, such
as contro l units, re lays, radio, etc., as well
