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
ma de. Other ki nds of changes may reduce the force levels meas ure d
by th e sensors a nd p rev ent the airbag from dep loying when it should.
T he sensors in the safety belt b uckle for the drive r and front

& 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.
CD 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 263. The 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 dealer must code the
battery in the energy manageme nt system to enable you to use the
energy management functions correctly after replacing the battery.
If it is not possible to use a battery of this type, the new battery must
have the same capacity, voltage (12 volts), amperage, construction
and plug sea ling. When
installing the battery, make sure the ignition and all electrical
consumers are turned off.
CD Note
Make sure the vent ilation 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 recom­
mend your authorized Audi dealer change the battery for you.
Batteries contain sulfu ric acid and lead and must always be disposed
of properly in compliance w ith all environmental regulations.
Disposing of vehicle batteries imprope rly is very dangerous to the
environment. •
