A discharged battery can freez e at tempera­
t ures of only O
0C. Allow a frozen batte ry to
thaw comp letely before a ttempting to charge
it ¢& . However, we recommend not using a
thawed battery again because the battery cas­
ing can be cracked due to ice formation and
can leak battery acid .
Battery charging (Ma ximum charging rate
o f 30 amp s/14 .8 Volt)
When charging at low voltages (e.g . w ith a
tric kle ch arger ), the battery cables do not
h ave to be d isconnected first. The battery
caps should
not be opened when charging a
battery .
It is not necessary to remove the battery from
the luggage compartment.
Checkin g and fillin g 269
Fast charging th e battery (cha rging rate
ab ove 14 .8 V olt s)
For technical reasons do not use a battery
charger that uses voltage greater than 14.8
Volts to charge your vehicle's battery.
A WARNING
~ -
Charging a battery can be dangerous .
-Always follow the operating instructions
provided by the battery charger manu­
facturer when charg ing your battery .
- Never charge a frozen battery.
It may ex­
plode because of gas trapped in the ice.
Allow a frozen battery to thaw out f irst.
- Do not reuse batteries wh ic h were fro­
zen. The battery hous ing may have
cracked and weakened when t he battery
froze.
- Charge the battery in a well ventilated area. Keep away from open flame or elec­
tr ica l spar k. Do not smoke. Hyd rogen gas
genera ted by the battery is explos ive .
- To reduce the danger of explosion, never
connect or d isconnect c harger cab les
while the charger i s ope rat ing .
- Fast cha rging a batte ry is dange rous and
should only be a ttempted by a compe­
tent techn ic ian wi th the p rope r equip­
men t.
- Battery acid tha t may spi ll dur ing cha rg­
ing should be washe d
off with a solu tion
of wa rm water and baking soda to neu ­
tralize the acid.
([) Note
Never use a fast charger as a booster to
star t the engine. This w ill seriously dam­
age sens it ive e lectronic com ponen ts, s uch
as contro l units, re lays, radio, etc., as well
as the batte ry charger. •

Battery replacement
The new battery must have the same specifi­
cations and dimensions as the original equip­
ment battery.
Intelligen t energy management in your veh i­
cle is respons ible for d istributing the e lectr i­
cal en ergy throughout your vehicle
¢ page 228. The intell igent e nergy manage­
ment system w ill keep the eng ine battery
cha rged better then vehicles w ithout this sys­
tem . To make sure the additional e lectrica l en ­
ergy is availab le once again after you have
changed the battery, we recommend that you install batteries of the same type and manu­
facture only (the same as those installed at
the time your vehicle was delivered). Specifi­
cations are listed on the battery hous ing . Your
author ized dealer must code the battery in
the ene rgy management system to enable you
to use the energy management funct ions cor­
rectly after replac ing the battery.
If it is not poss ible to use a battery of this
type, the new battery must have the same ca­
pac ity, voltage (12 volts), amperage , con­
struction and plug seal ing.
When insta lling the battery, make sure the ig­
n it ion and all e lectr ica l consumers a re turned
off.
Q;) Note
Make sure the venti lation hose on the s ide
of the battery is connected, otherwise
fumes or battery ac id can leak o ut.
@ For the sake of the environment
Because of the problem of proper d isposa l
of a battery, we recommend your autho r­
i z ed Audi dealer change the ba tte ry for
you. Bat teries contain s ulfu ric ac id and
lead and must always be disposed of prop ­
erly in compliance with all environmental
reg ulations. Disposing of vehicle batteries
improper ly is very dangerous to the envi­
ronment.

how to operate their equipment safely.
- Never tow your Audi , towing will cause
damage to the engine a nd transmi ssion.
- Never wrap th e safet y chain s or winch c a­
ble s around th e brak e lin es.
- To prevent unne ce ss ary dam age, your Aud i
mu st be t ransp orted with a flat bed truck .
- To load th e vehi cle on to the fl at bed, us e

fall from a lift if there is a change in ve­
hicle weight distribution and balance.
This might happen, for example, when
heavy components such as the engine
block or transmission are removed .
- When removing heavy components like
these, anchor vehicle to hoist or add cor­
responding weights to maintain the cen­
ter of gravity. Otherwise, the vehicle
might tilt or slip off the hoist, causing
serious personal injury.
(D Note
- Be aware of the following points before
lifting the vehicle:
-The vehicle should never be lifted or
jacked up from underneath the engine
oil pan, the transmission housing, the
front or rear axle or the body side
members. This could lead to serious
damage.
- To avoid damage to the underbody or
chassis frame, a rubber pad must be
inserted between the floor jack and
the lift points.
- Before driving over a workshop hoist,
check that the vehicle weight does not
exceed the permissible lifting capacity
of the hoist.
- Before driving over a workshop hoist,
ensure that there is sufficient clear­
ance between the hoist and low parts
of the vehicle.

owners.
Also, safe ty and e nvir onm en tal con­

Maintenance, adjustments and repa irs usua lly
require special tools, testing dev ices and oth­

workshop personnel in order to assure prope r
performance, reliab ility and safety of the vehi­

If in doubt about any servicing, have it done
by your authori zed Audi dealer or any other

A WARNING
-Ser ious personal injury may occur as a re­
sult of improperly performed mainte­ nance, adjustments or repa irs.
-Always be extremely care ful when work­
ing on the vehicle. Always follow com­
mon ly accepted safety pract ices and gen­
era l common sense . Never r isk personal
lnJU ry .
- Do not attempt any of the ma intenance ,
checks or repairs descr ibed on the fol­
lowing pages if you are not fully fam ilia r
wit h these or othe r pro cedures with re­

to p roceed .
- Do not do any work without the proper
too ls and equipment . Have the necessary
work done by your authorized A udi deal ­
er or another proper ly equipped and
qualified workshop .
- The engine compar tment o f any motor
veh icle is a potentially hazardous area.
Never reach into the area around or
touch the rad iator fan. It is temperature
contro lled and can switch on suddenly -
even when the engine is
off and the igni­
tion key has been removed. The rad iator
fan switches on automat ica lly when the
coo lant reaches a certai n temperatu re
a nd will cont inue to run until the coo lan t
tempera ture drops .
- Always remove the ign itio n key befo re
anyone gets under the vehicle.
- Always support your veh icle with safety
s tands i f it is necessary to work under­
neath the vehicle. The jack s upplied with
the vehicle is not adequate for this pur ­
pose and cou ld collapse causing serio us
personal injury.
- If you must work underneath the vehicle
with the wheels on the g round, a lways
make sure the vehicle is on leve l ground,
that the wheels are a lways securely
blocked a nd that the engine cannot be
started .
