208 Check ing and filling
for questions about the battery -danger
of acid burns and explosion hazard!
- The battery must not be opened! Do not try to change the battery's liq uid level ,
otherwise detonating gas will escape
from the battery- explosion hazard!
- The AGM battery in the luggage com­
partment cannot leak, because the elec­
trolyte for th is battery is absorbed into a
spec ial glass mat . Th is leak-proof battery
must not be replace with a conventional
battery .
- Make sure the ventilat ion hose on the
s ide of the battery is connected, other ­
wise fumes or battery acid can leak out .
- Battery ho lder and terminals a lways
have to be secured correctly .
- Before all work on the battery follow the
warning s below c> &. in Working on the
battery on page 208 .
Working on the battery
All work on the battery requires technical
knowledge! Be especially careful when work ­
ing on or near the battery!
Be fo re you check any thing in the engine com­
partment, always
r e ad a nd heed all WARN­
INGS
~ .&. in Working in the engine compart­
ment on page 194 .
Always heed the s afety warnings , when work­
i ng on the vehicle battery or the vehicle elec­
tr ica l system to preve nt injury .
The following WARNINGS are very
important when working on the battery:
Always heed the following WARNING SYM ·
BOLS and safety precautions when working on the battery.
Always wear eye protection.
Battery acid contains sulfuric
acid . Always wear glove s and
eye prote ction . No
• sparks
• flames
- smoking.
When a battery is charged , it
produces hydrogen gas which is
e x plosive and cou ld cause per­
sonal injury .
®
Always keep the battery well out
of reach of children.
A WARNING ,___
Whenever working on the battery or on
the electrical system, there is the risk of
i njury, accident and even fire . Read and
heed the following WARNINGS :
- Always wear eye protection . Do not let
battery ac id or any lead particles get on
your skin o r clothing . Shield you r eyes.
Exp losive gases can cause blindness or
o ther inju ry!
- Battery acid conta ins sulfuric acid. Sulfu­
ric acid can ca use blindness and severe
bu rns.
-Always wear g loves and eye protection.
Do not tilt the battery because acid
could leak out of the ventilat ion open­
ings .
- If you get battery ac id in your eyes or
on your skin, immediately rinse with
cold water for several minutes and get med ica l attent ion .
- If you shou ld ingest any battery acid,
seek medical attention immediately .
- Do not expose the batte ry to an open
flame, electr ic sparks or an open l ight.
- Do not smoke.
- Do not interchange the positive and neg-
ative cables.
- When working on the battery, be s ure
not to short-circu it the terminals w ith
too ls or othe r metal objects. Th is would
cause the battery to heat up very quickly,
which could lead to damage or explosion
-
and pe rsonal injury . ~

charged better then vehicles without this sys­
tem . To make sure the additional e lectrica l en ­
ergy is available 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 t ime your vehicle was delivered). Specifi­
cations are listed on the battery hous ing . Your
authorized dealer must code the battery in
the energy management system to enable yo u
to use the energy management functions cor­
rectly after replacing the bat tery.
If it is not possible to use a battery of this
type, the new battery must have the same ca­
pacity, voltage (12 volts) , amperage, con ­
struction and plug sealing.
We re commend that you use ma intenance­
free or
cy cle -re sis tant /le ak-proof batteries
that conform to the standards TL
825 06
(from December 1997) and VW 7 SO 73 (from
Aug ust 2001).
When insta lling the bat tery , make sure the ig­
n ition and all e lectrica l consumers are turned
off .
CD Note
-Make sure tha t the gas venting hose is
always connected to the o riginal open ing
on the battery side . Otherwise gasses or
battery acid could leak out.
- Battery mounts and clamps m ust always
be secured correctly.
- Read and follow the warnings under
C? page 208, Working on the battery be ­
fore performing any work on the battery .
@ For the sake of the environment
Because of the problem of proper d isposa l
o f a battery, we recommend your author ­
ized Audi dealer change the batte ry for
you. Batteries contain su lfuric ac id and
lead and must always be disposed of prop­
erly in compliance w ith all environmental
regu lations . D isposing of vehicle batte ries
improperly is very dangerous to the envi­
ronment. Make sure that the removed bat-
Checkin g and fillin g 211
tery cannot overbalance, otherwise su lfu ­
ric acid might escape!

Gro ss Axl e Weight Rating
The Gross Axle Weight Rating is the maxim um
l oad that can be applied at each axle of the
vehicle ~&. .
Vehicle capacity weight
The vehicle capac ity we ight (max . load) is list ­
ed eithe r on the dr iver's side B-pillar o r inside
the fuel filler flap.
Roof weight
The maximum perm iss ible roof we ight is 165
lb (75 kg ). The roof we ight is made up of the
weight of the roof ra ck system and the weight
of the object bei ng transpo rted
~ page 73 ,
Loading the roof rack .
A WARNING
- The actual Gross Axle Weight Rating at
the front and rear axles sho uld not ex­
ceed the perm iss ib le weights, and their
combination must not exceed the Gross
Vehicle Weight Rat ing .
- Exceeding permissib le we ight ratings can
result in vehicle damage, accidents and
personal in jury.
(D Note
- The vehicle capacity weight figures app ly
when the load is distrib uted evenly in the
vehicle (passengers and luggage) . When
transporting a heavy load in the luggage
compartment , carry the load as nea r to
the rea r axle as possib le so that the vehi­
cle's handling is not impa ired .
- Do not exceed the maximum permissible
axl e loads or the max imum g ross vehicl e
weig ht. Always remembe r that the vehi­
cl e's handling will be affected by the ex­
tra load . Therefore, adjust your speed ac­
cordingly.
- Alw ays obse rve lo cal regulations.

260 Consumer Inf ormation
Important considerations for you and
your vehicle
The increasing use of e lectronics, sophisticat­
ed fue l injection and emission control sys­
tems, and the generally increasing technical
comp lexity of today's automob iles, have
steadi ly reduced the scope of maintenance
and repairs which can be carried out by vehicle
owners .
Also , safet y and en vironm ental con­
cerns p lace very strict lim its on the nature of
repairs and adjustments to eng ine and t rans­
miss ion parts which an owner can pe rform .
Ma intenance, adjustments and repa irs usually
require special tools, testing dev ices and oth­
e r equipment avai lab le to specia lly t ra ined
workshop personne l in order to assure prope r
pe rformance, reliab ility and safety of the vehi­
cle and its many systems.
I mp roper ma intenance, adjus tments and re­
pa irs can impai r the operation and reliab ility
of your vehicle and even void you r vehicle war­
ranty . There fore, proof of servicing in accord­
ance wit h the ma intenance sched ule may be a
condition for upholding a poss ible warranty
claim made within the warranty period.
Above all, operational safety can be adversely
affected, c reating unnecessary risks for you
and your passengers .
I f in do ubt about any serv icing, have it done
by your authorized A udi dealer or any other
p roperly equipped and qualified workshop .
We strong ly urge you to give yo ur authorized
Aud i dealer the opportunity to perform all
schedu led maintenance and necessary repairs.
Your dea le r has the facilities, or iginal parts
and trained spec ialists to keep your vehicle
running prope rly .
Performing lim ited maintenance yourself
The follow ing pages describe a limited num­
ber of procedures which can be performed on
your ve hicle w ith ordi nary too ls, should the
need a rise and trained pe rsonnel be unavaila­
b le. Before perfo rming any of these proce­
du res, always tho roughly read a ll of the app li­
