e lectronic engine immobilizer and permit
an unauthorized person to start the engine
and enable operation of the vehicle sys­
tems such as power window or power sun­ roof leadi ng to se rious pe rsonal injury.
@ Tips
- The ve hicle cannot be started if an una u­
thorized key is used. The vehicle may not start if another radio device s uch as a key

your vehicle will unnecessarily use more
fuel. Remove the roof rack if you are not
going to use it.

- Never connect eq uipment that generates
electrical current, such as a solar panel
or battery charger, to the 12 volt socket .
Th is could damage the vehicle 's electri­
cal system.
- The 12 volt socket sho uld only be used
for a short per iod of t i me as a powe r
so urce for electrical equipme nt. Please

236 Checking and filling
-Never charge a frozen battery. It may ex­
plode because of gas trapped in the ice.
Allow a frozen battery to thaw out first.
- Do not reuse batteries which were fro­
zen. The battery housing may have cracked and weakened when the battery
froze .
- Charge the battery in a well ventilated
area . Keep away from open f lame or elec­
trical spark . Do not smoke. Hydrogen gas
generated by the battery is exp losive.
- To reduce the danger of explosion, never
connect or disconnect charger cables
wh ile the charger is operating.
- Fast charg ing a battery is dangerous and
should only be attempted by a compe­
tent technician with the proper equip­
ment.
- Battery acid that may spill during charg­
ing should be washed
off with a solution
of warm water and bakin g soda to neu­
tralize the acid.
Never use a fast charger as a booster to
start the engine. This will se riously dam­
age sensitive electronic components, such
as control units, relays, radio, etc., as we ll
as the battery charger .
Battery replacement
The new battery must have the same specifi­
cations and dimensions as the original equip­
ment battery.
I ntell igent energy management in your vehi­
cle is respo nsible for distributing the electr i­
cal energy throughout your vehicle
c::> page 195. The intelligent energy manage­
ment system wi ll keep the engine battery
charged better than vehicles without this sys­
tem. To make sure the additional electrical en­
ergy is available once again after you have
changed the battery, we recommend that you install batte ries of the same type and man u­
facture only (the same as those installed at
the time 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 enab le you
to use the energy management functions cor­
rectly after replacing the battery.
T he new battery must have the same capacity,
voltage (12 volts), amperage, construction and plug sealing .
When installing the battery, make sure the ig ­
nition and all electrical consumers are switch­
ed off.
(D Note
Make sure the ventilation hose on the side
of the battery is connected, otherwise
fumes or battery acid can leak out .
@ For the sake of the environment
Because of the prob lem of proper disposal
of a battery, we recommend your author­
i zed Audi dealer change the battery for
you. Batteries contain sulfuric acid and
lead and must always be disposed of prop­
erly in compliance with a ll environmental
regulations. Disposing of veh icle batter ies
improperly is very dangerous to the envi­
ronment .
