replaced -risk of injury .
• With gas-discharge lamp s* (xenon headlights ), the high­
voltage component mu st be handled appropriately. Doing other ­
wise poses a ri sk of death!

-Fuel supply and filling your fuel tank
P:Vf------=-=----------=-:o..------------
To avoid fu el sp illin g o r evaporat ing from th e fue l tank a lways clos e
fu el cap prop erl y and com plete ly.
& WARNING
Improper refueling or handling of fuel can cause fire, explosion
and severe burns .
• Fuel is highly flammable and can cause severe burns and other
injuries.
• Failure to shut the engine off while refueling and /or to insert
the pump nozzle fully into the fuel filler neck could cause fuel to
spray out of filler neck or to overflow. Fuel spray and overflowing
fuel can cause a fire.
• Never use a cellular telephone while refueling. The electromag­
netic radiation can cause sparks that can ignite fuel vapors and
cause a fire.
• Never get back into your vehicle while refueling. If in excep­
tional circumstances you must get back in your vehicle while refu­ eling, make certain that you close the door and touch metal to
discharge static electricity before touching the filler nozzle again.
Static electricity can cause sparks that can ignite fuel vapors
released during refueling.
• Never smoke or have an open flame anywhere in or near your
vehicle when refueling or filling a portable fuel container.
• For your safety, we strongly recommend that you do not travel
with a portable fuel container in your vehicle. The container, full or empty may leak and could cause a fire, especially in a crash .
• If, under exceptional circumstances, you must transport a
portable fuel container , please observe the following:
- Never fill a portable fuel container while it is anywhere in or
on the vehicle (for example, in the luggage compartment, or
on the trunk). Static electricity can build up while filling and
can ignite fuel vapors causing a fire.
- Always place a portable fuel container on the ground before
filling.
& WARNING (co ntinued )
-Always keep the filler nozzle completely inside the portable
container before and during filling .
- If filling a portable container made of metal, the filler nozzle
must always be in contact with the container. This will help
prevent static electricity from discharging and cause a fire.
- Never spill fuel inside the vehicle or luggage compartment .
Fuel vapors are highly flammable.
- Always observe local and state/provincial laws regarding the
use, storage and transportation of fuel containers.
- Make certain the fuel container meets industry standards
(ANSI/ ASTM F852-86).

Battery charging (Ma ximum charging rate of 30
amp s/14.8 Volt)
When charging at low vol tages (e.g. w ith a trickle charger ), the
b attery cables do not have to be disconnected first. The batte ry caps
should
not be opened when charging a batte ry .
It is not necessary to remove the battery from the luggage compart-

Fast charging the battery (charging rate above 14 .8
Volts)
For technical reasons do not use a battery charge r that uses voltage
greater than 14.8 Volts to charge yo ur vehicle's battery.
& WARNING
Charging a battery can be dangerous.
• Always follow the ope rat ing instructions provided by the
battery charger manufacturer when charging your battery .
• Never charge a frozen battery. It ma y explode because of gas
trapped in the i ce . Allow a frozen battery to thaw out first .
• Do not reuse batteries which were frozen . The battery housing
may hav e cra cked and weakened when th e batter y froze.
• Charge the battery in a well ventilated area . Keep away from
open flame or electr ical spark . Do not smoke . Hydrogen gas gen er­
ated by the battery i s explosive.
• To reduce the danger of explo sion, n ever conne ct or dis connect
c harger cables while the charger is operating.
• Fast charging a battery is dangerous and should only be
attempted by a competent te chnician 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 eng ine. This w ill seri­
ous ly damage sens itive elect ronic components, such as control units,
re lays, rad io, etc., as well as the battery charger. •
Safety first
Battery replacement
The ne w ba ttery must have the same spe cific ations and
dimensions as the original equi pment battery.
Inte lligent energy management in your veh icle is responsible for
dist ributing the ele ct ric a l ene rgy t hroughout yo ur veh icle
~ page 243. The intelligent energy management system will keep
t he eng ine ba ttery c ha rged better then vehicles wi thou t this system.
To make sure the additional e lectrical energy is available once again
after you h ave changed the ba tte ry, we re commend t hat yo u inst all
batter ies of the same type and ma nufacture only (the same as t hose
installe d at the time your ve hicle was delivere d). Specifications a re
listed on the battery housing . Your authorized Aud i dealer must code
the batte ry in the energy management system to enable you to use
the energy management f unctions co rrectly after rep laci ng the
battery.
If it is no t poss ibl e to use a batte ry of thi s ty pe, the new ba tte ry mus t
have the same capac ity , voltage (12 volts) , amperage , construction
and plug sea ling .
Whe n ins tal ling the ba ttery, make sure the ign it io n and a ll electr ica l
cons umers are turned off.
0 Note
Make s ure t he venti lation hose on the s ide of the battery is
co nnected, o the rwise fumes or battery acid can lea k out.
W For the sake of the environment
B ecau se of the p roblem of proper di sposal of a ba tte ry, we recom ­
mend your authorized Audi dealer change the battery for you.
B atteries con tain sulfuri c acid and lead and m ust always be dispose d
of properly in comp liance w it h all environmental regulations.

& WA RNING (co ntinued )
• Before you che ck anything in the engine compartment , always
read and heed all WARNINGS~
page 267, "Engine compart­
ment ".
0 Note
• App lying a higher vo ltage booster battery will cause expensive
damage to sens itive e lec tron ic components, such as contro l units,
re lays, rad io, etc.
• Th ere must be no electrical contac t between the vehicles as othe r­
wise current could a lready start to flow as soon as the posit ive(+)
t erm inals are con nected.
[I] Tips
• Th e discharged ba tte ry mus t be properly co nnecte d to the
vehicle's electrical system . When jump starting or charging the
bat tery, never connec t the negat ive ground cable to the batte ry nega­
tive post because the battery manager system must be able to detect
t he battery's state of charge . Always connect the negative ground
cable to the negative ground post of the battery manage r contro l
unit. •
