remote control
- To fold the key out and back in place, press the release
button~ fig. 24.
The transmitter and battery are located in the head of the remote
control. The receiver is located inside the vehicle. The maximum
effective range depends on several things . Remember, 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.
Personalizing the master key
When the ignition is turned off or when the vehicle is locked, various
convenience settings are stored automatically and assigned to the
key that was used. The settings that are assigned to the master key
are reca lled automatically when the vehicle is unlocked, when the
door is opened or when the ignition is switched on.

Other things that can affect Advanced
Airbag performance
Chang ing the vehicle's suspension system can change the way that
th e Adva nced Airbag System pe rforms i n a cr ash. Fo r examp le, us in g
t ire-rim combinations not approved by Audi, lowering the vehicle,
c hang ing the stiffn e ss o f th e suspension, incl uding t he sp rings,
suspension struts , shock absorbers etc. can change t he forces that
are meas ured by the a irbag sensors an d sent to the elect ronic contro l
unit . Some suspension c hanges can, fo r example, increase the force
levels meas ure d by the senso rs and make the airbag system deploy in
crashes in which i t would not deploy if the changes had not been

& WARNING (continued)
• To reduce the danger of explosion, never connect or disconnect
charger cables while the charger is operating.
• Fast charging a battery is dangerous and should only be
attempted by a competent technician with the proper equipment.
• Battery acid that may spill during charging should be washed
off with a solution of warm water and baking soda to neutralize
the acid.
0 Note
Never use a fast charger as a booster to start the engine. This will seri­
ously damage sens it ive electronic components, such as control units,
relays, radio, etc ., as well as the battery charger.•
Battery replacement
The new battery must have the same specifications and
dimensions as the original equipment battery.
Intelligent energy management in your veh icle is responsible for
distributing the electrical energy throughout your vehicle
~ page 259. T he intelligent energy management system will keep
the engine battery charged better then vehicles without this system .
To make sure the additional electrical energy is available once again
after you have changed the battery, we recommend that you install
batteries of the same type and manufacture only (the same as those
installed at the time your vehicle was delivered). Specifications are
listed on the battery housing. Your authorized Audi dealer will then
code the battery management control unit.
If it is not poss ible to use a battery of this type, the new battery must
have the same capacity, vo ltage (12 volts), amperage, construction
and plug sea ling .
When installing the battery, make sure the ignition and all electrica l
consumers are turned off.
0 Note
Make sure the vent ilation hose on the side of the battery is
connected, otherwise fumes or battery acid can leak out.
Because of the problem of proper disposal of a battery, we recom­
mend your authorized Audi dealer change the battery for you.
Batteries contain sulfuric acid and lead and must always be disposed
of properly in compliance with all environmental regulat ions.
Disposing of vehicle batteries improperly is very dangerous to the
environment. •
