A d ischarged bat tery can freeze at tempera­
tures of only 32 °F (0 °C) . Allow a frozen bat­
tery to thaw completely before attempting to cha rge it
c::, .&. . However, we recommend not
u sing a thawed batte ry aga in because the bat­
tery casing can be cracked due to i ce fo rma­
tion an d can leak b attery a cid.
Battery charging (Maximum charging rate
of 30 amps /14.8 Volt )
When charg ing at low vo ltages (e.g. wi th a
t rickle charger ), the ba tte ry cables do no t
have to be disconne cte d firs t. T he bat tery
caps should
not be opened when charging a
batte ry .
It is no t necessa ry to remove the b attery from
the luggage compartment.
Fast charging the battery (charging rate
above 14 .8 Volts)
Fo r tec hni cal re asons do not use a bat tery
c h arger that uses voltage g reater than
1 4 .8
Volts to c harge yo ur veh icle's battery.
A WARNING
C harging a battery can be dangero us.
-A lways follow the operati ng instr uctions
provided by the battery charger manu ­
facturer when charging your battery .
- Never charge a fro zen battery. It may ex­
p lode because of gas trapped in the ice .
A llow a frozen battery to thaw out first.
- Do not reuse batteries wh ic h were fro­
zen. The battery housing may have
cracked and weakened w hen the battery
froze.
- Charge the battery in a well venti lated
area . Keep away from open flame or elec­
trical spark. Do not smoke . Hydrogen gas
generated by the battery is explos ive . ..,

208 Check ing and filling
- To r educe the danger of explosion, never
co nnect or disconn ect cha rger cables
wh ile the c harger is operating.
- Fast char ging a battery is dangerous and
shou ld on ly be attempted by a compe­
tent technician w ith the proper equip­
ment .
- Battery acid that may spill during charg­
ing should be washed
off with a solution
of warm water and baking soda to neu ­
tralize the acid.
(Q) Note
Never use a fast charger as a booster to
start the engine . This will seriously dam­
age sensitive electronic components, such
as control units, relays, rad io, etc., as we ll
as the battery charger.
Battery replacement
The new battery must have the same specif/·
cations and dimensions as the original equip­
ment battery.
Intell igent energy management in your veh i­
cle is respons ible for d istributing the e lectr i­
cal energy throughout you r vehicle
q page 177. The intell igen t energy m anage­
men t system w ill keep the engine ba tte ry
charged better then vehicles w ithout 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 o f the same type and ma nu­
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 Audi dealer must code the battery
in the ene rgy management system to enable
you to use the energy management functions
correctly after replac ing the battery.
I f it is not poss ible to use a battery of this
type, the new bat tery m ust h ave the s ame ca­
pac ity, voltage ( 12-volts), amperage, con ­
struction and plug sea ling. When installing the battery, make su
re the ig ­
nition and a ll electrical consumers are turned
off.
(D Note
Make sure the ventilation hose on the side
of the battery is connected, otherwise
fumes or battery acid can leak out .
@ For the sake of the environment
Because o f the p rob lem of p roper disposal
of a battery, we recommend your author ­
i zed Audi dealer change the battery for
you. Batteries contain sulfur ic acid and
l ead and must always be disposed of prop­
erly in comp liance with all environmental
regulations. Dispos ing of vehicle batter ies
i mprope rly is very dange rous to the envi­
r o nment .

If you wish to improve comfort
when operating the vehicle at
normal load (up to 2 occu­
pants), you can adjust tire
pressures to those specified
for normal vehicle load. Before
operating the vehicle at maxi­ mum load, you must increase
the tire pressures to those
specified for maximum vehicle
load
c> .&. .
Bear in mind that the tire pres­
sure monitoring system* can
only monitor the tire pressures
you have stored. The system does not recognize the load
condition of your vehicle.
The effectiveness of the tire p ressure monitoring system*
will be impaired if you store normal load pressures but then
operate the vehicle at its maxi­
mum load

Bulbs
Replacing bulbs
For your safety, we recommend that you hove
your authorized Audi dealer replace any bulbs
for you .
It is becoming increasingly more and more
difficult to replace vehicle light bulbs since in
many cases, other parts of the car must first
be removed before you are able to get to the
bulb. This applies especially to the light bulbs
in the front of your car which you can only
reach through the engine compartment.
Sheet metal and bulb holders can have sharp
edges that can cause serious cuts, parts must
be correct ly take n apa rt and then p roperly put
bac k together to he lp p revent breakage of
parts and long te rm damage from water that
can enter housings that have not been p roper­
ly re sea led .
Fo r you r safety, we re commend that you have
your autho rized Audi de aler replace any b ulbs
f or you, since your dealer has the proper too ls,
the correct bulbs and the expertise.
Gas disc har ge la mp s (Xenon l ig hts)*:
Due to the high electr ical voltage, have the
bulbs replaced by a qualified techn ic ian .
Head lights w ith Xenon light are identified by
the h igh vol tage sticker.
_&. WARNING
Changing Xenon lamps without the neces­
sary equipment can cause serious persona l
injury .
- Bulbs are pressurized and can explode
when being changed. Potential risk of in­
jury!
-
•
•

254 Fuse s a nd bul bs
-On vehicles equipped with gas discharge
bulbs (Xenon light)* life-threatening in­
juries can result from improper handling of the high-voltage portions of such
lamps!
- Only your authorized Audi dealer or
qualified workshop should change the
bulbs in gas d ischarge lamps. There are
parts with sharp edges on the openings
and on the bulb holders tha t can cause
serious cuts. If you are uncertain about
what to do, have the work performed by an authorized Audi dealer or qualified
workshop. Serious personal injury may result from improperly performed work.
(D Tips
- If you still p refer to replace the light
bulbs yourself, be aware that the engine
compartment is a hazardous area to
work ini=>poge
195 '=> A.
-It is best to ask your authorized Audi
dealer whenever you want to change a
bulb.

Emergency situations
General
This chapter is intended for trained emer­
gency crews and working personnel who have the necessary tools and equipment to
perform these operations.
Starting by pushing or
towing
(D Note
Vehicles with an automatic transmission
cannot be started by pushing or towing.
Starting with jumper
cables
If necessary, the engine can be started by
connecting it to the battery of another vehi­
cle.
If the engine should fail to start because of a
discharged or weak battery, the battery can be
connected to the battery of
another vehicle,
using a
pair of jumper cables to start the en­
gine.
Jumper cables
Use only jumper cables of sufficiently
largecross section to carry the starter current
safely. Refer to the manufacturer's specifica­
tions.
Use only jumper cables with
insulated termi­
nal clamps which are distinctly marked:
plus(+) cable in most cases colored red
minus(-) cable
in most cases colored black .
A WARNING
Batteries contain electricity, acid, and gas.
Any of these can cause very serious or fatal
injury. Follow the instructions below for
safe handling of your vehicle's battery.
- Always shield your eyes and avoid lean­
ing over the battery whenever possible.
Emergency situations 255
-A discharged battery can freeze at tem­
peratures just below 32 °F (0 °C). Before
connecting a jumper cable, you must
thaw the frozen battery completely, oth­
erwise it could explode.
- Do not allow battery acid to contact eyes
or skin . Flush any contacted area with
water immediately .
- Improper use of a booster battery to
start a vehicle may cause an explosion.
- Vehicle batteries generate explosive gas­
es. Keep sparks, flame and lighted ciga­
rettes away from batteries.
- Do not try to jump start any vehicle with
a low acid level in the battery.
- The voltage of the booster battery must
also have a 12-Volt rating. The capacity
(Ah) of the booster battery should not be
lower than that of the discharged bat­
tery. Use of batteries of different voltage
or substantially different "Ah" rating
may cause an explosion and personal in­
jury.
- Never charge a frozen battery. Gas trap­
ped in the ice may cause an explosion.
- Never charge or use a battery that has
been frozen. The battery case may have
be weakened.
- Use of batteries of different voltage or
substantially different capacity (Ah) rat­
ing may cause an explosion and injury.
The ca pa city (Ah) of the booster battery
should not be lower than that of the dis­
charged battery.
- Before you check anything in the engine
compartment, always read and heed all
WARNINGS
c::;,page 195.
(D Note
-Applying a higher voltage booster bat­
tery will cause expensive damage to sen­
sitive electronic components, such as
control units, relays, radio, etc.
- There must be no electrical contact be­ tween the vehicles as otherwise current
could already start to flow as soon as the
positive(+) terminals are connected. ..,. •
•

256 Emergency situations
@ Tips
The discharged battery must be properly
connected to the vehicle's electrical sys­
tem. When jump starting or charging the
battery, never connect the negative
ground cable to the battery negative post
because the batte ry manager system must
be able to detect the battery 's state of
charge. Always connect the negative
ground cab le to the negative ground post
of the battery manager control unit.
Use of jumper cables
Make sure to connect the jumper cable
clamps in exactly the order described below!
