244 Checking and filling
Vehicles not driven for long periods
If you do not drive you r vehicle over a pe riod
of severa l days or weeks, electrical compo­
nents are gradually cut back or switched off.
This reduces energy consumption and main­
tains starting capability over a longer period
¢page 203.
Take into consideration that when yo u un lock
your vehicle, some convenience functions, such as the interior lights or the power seat
adjustment, may not be available. The con­
venience funct ions w ill be available again
when you turn on the ignition and start the
engine .
Winter operation
During the winter months, battery capacity
tends to decrease as temperatures drop . This
is because more power is also consumed while
start ing, and the headl ights, rear window de­
fogger, etc., are used more often .
Avoid unnecessary power consumption, par­
ticularly in city traffic or when traveling only
short distances . Let your authorized Audi
dealer check the capacity of the vehicle bat­
tery before winter sets in¢
page 245. A well
cha rged battery w ill not only prevent starting
prob lems when the weather is cold , but will
a lso last longer .
Working on the battery
Be especially careful when working on or near
the battery.
The battery is located in the luggage compart­
ment under the floor. Before you check any­
thing in the luggage compartment,

-Do not interchange the positive and neg­
ative cables .
- When working on the battery , be sure
not to short-circuit the terminals with
tools or other metal objects. This would cause the battery to heat up very quickly,
which could lead to damage or explosion
and personal injury.
- When a battery is charged, it produces
hydrogen gas which is explosive and
could cause personal injury .
- Always keep the battery well out of the
reach of children .
- Before work is done on the electrical sys­
tem, disconnect the negative ground ca ­
ble .
- Before performing any work on the elec ­
trical system , switch off the engine and
ignition as well as any electrical equip­
ment. The negative cable on the battery
must be disconnected. If you are just go­
ing to replace a light bulb, then it is
enough to switch off the lights.
- Before disconnecting the battery , switch
off the anti-theft alarm system! Other­
wise you will set off the alarm.
- When disconnecting the battery, first
disconnect the negative cable and then
the positive cable.
- Before reconnecting the battery, make
sure all electrical consumers are switch­
ed off. Reconnect the positive cable first
and then the negative cable. Never inter­
change the cables - this could start a fire!
- Never charge a fro zen or a thawed-out
battery. It could explode! If a battery has
frozen, then it must be replaced. A dis­
charged battery can freeze over at 32°F
(OOC) .
-Make sure the vent hose is always attach­
ed to the opening on the side of the bat ­
tery.
- Never use batteries which are damaged.
There is the danger of an explosion! Al­
ways replace a damaged battery.

A WARNING
California Proposition 65 Warning:
- Battery posts, terminals and related ac­ cessories contain lead and lead com­
pounds, chemicals known to the State of
California to cause cancer and reproduc ­
tive problems . Wash hands after han­
dling.
Q) Note
- Do not disconnect the vehicle battery
when the ignition is switched on or when
the engine is running, otherwise , you will
damage electronic components in the
electrical system.
- If your vehicle is going to stand for a
long period of time without being driven,
protect the battery from "freezing", oth­
erwise it will be damaged and will then
have to be replaced.
Battery charging
Starting the engine requires a well charged
battery.
Fig. 201 Engin e compart ment: Co nn ectors for charger
and j umper cab les
Always read and heed all WARNINGS below
¢ .&. and ¢,&. in Working on the battery on
page 244.
~ Hybrid drive*: read the important informa­
tion concerning a dead high voltage battery
under
¢ page 105.
~ Turn off the ignition and all electrical con­
sumers.
~ Make sur e the area is well ventilated when
you charge the battery . ..,.

install batteries of the same type and manu­
facture only (the same as those installed at
the t ime your vehicle was delivered) . Specifi ­
cations are listed on the battery housing. Your
authorized dealer must code the battery in
the energy management system to enable you
to use the energy management functions cor­ rectly after replacing the battery .
If it is not possible to use a battery of this
type, the new battery must have the same ca ­
pacity, voltage (12 volts), amperage, con­
struction and plug sea ling .
When installing the battery, make sure the ig­
nition and all electr ica l consumers are turned
off.
(D Note
- Make sure the ventilation hose on the
s ide of the batte ry is connected, other­
wise fumes or battery acid can leak out .
- Vehicles with the Start-Stop-System* are
equipped with a special cycle-proof AGM
battery . Installing a different type of
battery can cause problems in the vehi­
cle elec trical system. When replacing the
vehicle battery, always insta ll one with
the same specifications as the original
battery.
@ For the sake of the environment
Because of the problem of proper disposal
of a battery, we recommend your author ­
ized Audi dealer change the battery for
you. Batteries contain su lfuric acid and
lead and must always be disposed of prop­
erly in compliance with all environmental
regu lations . D isposing of vehicle batteries
improperly is very dangerous to the envi­
ronment .
