A d ischa rged batte ry can freeze at tempe ra­
tures of only 3 2 F
0 (0 °C). Allow a fro zen bat­
te ry to thaw completely before attemp ting to
c h arge it
c::> & . However, we recommend not
using a thawed battery again because the bat­
tery casing can be cracked due to ice forma­
tion and can leak battery ac id.
Battery charging (Maximum charging rate
of 30 amps /14.8 Volt )
When cha rging at
low vo ltages (e .g. with a
trickle charger), the batte ry cables do not
have to be disconnected f irst . The battery
caps should
not be ope ned when charg ing a
batte ry .
It is not necessary to remove the battery from
the luggage compartment, and it is a lso not
necessary to d iscon nect the cab les .
Fa st charging the battery (cha rging rate
above 14.8 Volts)
Fo r technical reasons do not use a battery
c h a rger that uses voltage g reater than 14 .8
Volts to charge yo ur vehicle's battery .
A WARNING
C harging a battery can be dangero us.
- Always follow t he ope rati ng inst ructions
provi ded by the battery cha rg er ma nu­
f ac turer when chargi ng you r battery.
- N ever cha rge a fro zen batte ry.
It may ex­
p lode because of gas trapped in the ice .
A llow a froz en ba tte ry to thaw out first.
- D o not r euse ba tte ries wh ich were fro­
z en. The bat tery housi ng may

cracked an d weake ned when the battery
froze.
- Charge the battery in a we ll ventilated
area. Keep away from open flame or elec­
trical spark . Do not smoke. Hydrogen gas
generated by the battery is exp losive.
- To reduce the danger of explosion, never
connect or disconnect charger cables
wh ile the charger is operating .
- Fast charg ing a battery is dangerous and
should only be attempted by a compe­
tent technician w ith the proper equip ­
ment .
- Battery acid that may spill d uring charg­
ing should be washed off w it h a solution
of warm water and ba kin g soda to neu­
t rali ze the acid.
~ Note
Never use a fast charger as a booster to
start the engine. This will seriously dam ­
age sensitive ele ct ronic components, such
as co ntrol units, relays, rad io, etc. , a s we ll
as th e batte ry charge r.
Battery replacement
The new battery must have the same specifi­
cations and dimensions as the original equip­
ment battery.
I ntell igent energy manag ement in your veh i­
cle is respo nsible for d ist ribu ting the e lectr i­
cal energy throughou t you r vehi cle
~ page 193. The inte lligen t energy m anage­
ment system w ill keep the engine batte ry
charged better than vehicles w it h out t his sys­
tem . T o make sure the additional e lectrical en ­
ergy is available once again after you have
changed t he battery, we recommend that you
install batteries of the same type and manu ­
facture only (the same as those ins talled at
the t ime your vehicle was delivered). Specifi­
cations a re listed o n the battery hous ing. You r
author ized de aler m ust code the b attery in
the ene rgy management system to enable yo u
to use the energy managemen t fu nctions co r­
rectly after replac ing the battery. T
he new battery must have the same capacity,
vo ltage ( 12-volts) , amperage , construction
and plug sea ling .
When ins tall ing t he battery, make su re the ig­
nition and a ll elect rical consume rs are switch ­
ed off .
(D Note
M ake sure the ven tilat ion hose on the side
of the ba ttery is connecte d, otherwise
fumes or batte ry acid can lea k out .
@ For the sake of the environment
B ecause o f the p rob lem of p roper disposal
of a battery, we recommen d your author ­
i zed Audi dea ler chan ge the battery for
you . Batteries contain sul fur ic acid and
l ead and must a lways be disposed of p rop­

and repairs which can be carried o ut by vehicle
owners.
Also, safe ty and en vironment al con­
cerns p lace very strict limits on the nature of
repairs and adjustments to engine and trans­
miss io n parts which an owner can perform .
Maintenance, adjustments and repa irs usua lly
require special tools, testing devices and oth­
er equipment availab le to specially trained
workshop personne l in order to assure proper
pe rformance, reliab ility and safety of the vehi­
cle and its many systems .
Improper ma intenance, adjustments and re­
pa irs can impair the operation and reliability
of your vehicle and even void your vehicle war­
ranty. Therefo re, p roof of servic ing in accord­
ance w ith the maintenance schedule may be a
condition for upholding a poss ible war ran ty
claim made within the warranty period .
Above all, operational safety can be adversely
affected, creating unnecessary risks for you
and your passengers .
If in do ubt about any serv icing, have it done
by your authorized Audi dealer or any othe r
p roperly equipped and q ualified works hop .
We strong ly urge you to give yo ur auth o rized

Your dea ler has the facilities, original parts
and tra ined spec ialists to keep your vehicle
running properly.
Performing limit ed ma inten ance yourself
The fo llow ing pages describe a limited num­

_& WARNING
- Ser ious personal injury may occur as a re­
sult of improperly performed mainte­
nance, ad justments or repa irs .
- Always be extremely ca reful when work­
ing on the vehicle . Always follow com­
monly accep ted safety pract ices and gen­
era l common sense. Never r is k personal
inju ry.
- Do not attempt any of the maintenance,
checks or repairs descr ibed o n the fol­
lowing pages if you are not fully familia r
wit h these or othe r procedures with re­
spect to the ve hicl e, or are uncertain how
to p roceed .
- Do not do any work without the proper
too ls and equipment. Have the necessa ry
wo rk done by your authorized A udi deal­
er or another proper ly equipped and
qualified wor kshop.
- The engine compartment of any motor
veh icle is a potentially hazardous area.
Never reach into t he area around or
touch the rad iator fan. It is temperature
contro lled and can switch on suddenly -
even when the engine is off. The radiato r
fan switches on automat ically when the
coo lant reaches a certain tempera ture
and will cont inue to run until the coo lant
temperature drops .
- Always sw itch o ff the ignition before any­
one gets under the vehicle.
- Always support your veh icle with safety
s tands if it is necessary to work under­
neath the vehicle. The jack s upplied with
the vehicle is not adequate for this pu r­
pose and cou ld collapse causing serio us
personal injury.
- If you m ust wor k unde rneath the vehicle
with the wheels on the g round, a lways
make sure the vehicle is on leve l ground,
that the wheels a re a lways securely
blocked a nd that the engine cannot be
started.
