The transmitter and battery are located in the
h ead of the remote control. The receiver is lo­
cated inside the vehicle. The maximum effec­
tive range depends on seve ral things. Remem­
ber, if the battery is weak, the effective range
decreases.
If you need to replace the remote control, or if
you need to have it repaired, you must see
your authorized Audi dealer. Only then can
you use the key again.
@ Tips
- If the ignition is sw itched on, the remote
control system is deactivated.
- The remote control system can be affect­
ed by other systems operating in the
same frequency range close to the vehi­
cle, such as mobi le telephones, te levi­
s ion broadcasting stations, etc.

Electronic immobilizer
The immobilizer helps to prevent unauthor­
ized use of your vehicle .
A computer chip inside your key automat ica lly
deactivates the e lectronic immobilizer when
you insert the key in the ignition lock . When
you remove the key from the ignition lock, the e lectronic immobilizer is a utomatica lly acti­
vated once again.
@ Tips
- The vehicle cannot be started if an unau­
thorized key is used. The vehicle may not
start if another radio device such as a key
for another vehicle or transponder is lo­
cated on the key ring.

Chargi ng the b attery
Only use chargers with a m ax im um cha rg in g
v oltage o f
14.8 V. The battery connecting ca­
bles do not need to be disconnected. Do not
open the battery when charging.
Read all of the manufacturer's instructions for
the charger before charting the battery.
It is not necessary to remove the battery from
the engine compartment, and it is a lso not
necessary to disconnect the cables.
Normally, a battery should be charged at no
more than 10 percent of its rated capacity.
For example, a charging current of 4.5 amps
wo uld be used on a battery rated at 45 Ah.
Rated capacity of the battery in your veh icle is
listed on the battery housing .
The battery caps shou ld
not be opened when
cha rg ing a battery.
_& WARNING
Cha rging a battery can be dangerous.
- Never charge a frozen battery. It may ex­
plode because of gas trapped in the ice .
Allow a frozen battery to thaw o ut first .
- Do not reuse batteries which we re fro­
zen. They must be replaced. The battery
housing may have cracked and weakened
when the battery froze.
- Charge the battery in a we ll ventilated
area. Keep away from open f lame or elec­
trical spark. Do not smoke. Hydrogen gas generated by the battery is explosive. -
To reduce the danger of exp losion, never
connect or d isconnect charger cab les
while the charger is operating.
- Fast charging a battery is dangerous and
should only be attempted by a compe­
tent techn ic ian with the proper equip­
ment.
- Battery acid that may sp ill dur ing charg­
ing should be washed off with a solut ion
of warm water and baking soda to neu­
tralize the ac id.
{[) Note
-Make sure that the gas venting hose is
always connected to the or iginal opening
on the battery s ide. Otherwise gasses or
battery acid could leak out.
- Never use a fast charger as a booster to start the engine. This will seriously dam­
age sensitive electron ic components,
such as contro l units, re lays, radio, etc.,
as well as the batte ry charger.
- T he vehicle may be optionally equ ipped
w ith a gel battery, wh ich can only be
charged at a cons tant current-lim ited
voltage . To prevent damage to the bat ­
tery and the electronics system, a gel battery that is connected must under no
circumstances be charged with a quick
charger.
{!) Tips
- The vehicle battery must not be charged
with a standard small charger that pl ugs
into the outlet.
- Only charge the battery through the con­
nections in the engine compartment.
