(D Note
-Do not disconnect the ve hicle battery
when the ignition is on or when the en­
gine is running, otherwise, you will dam­
age electronic components in the electri­
cal system .
- If your vehicle is going to stand for a
long period of time without being driven,
protect the battery from "freezing", oth­
erwise it will be damaged and w ill then
have to be replaced.
Battery charging
Starting the engine requires a well charged
battery.
Fig. 193 Engine compartment: connectors for a charg­
er and jump sta rt cables
Always read and heed all WARNINGS below
c::, &. and c::, &. in Working on the battery on
page 236 .
.,. Switch off the ignit ion and all electrical con­
s umer s.
.,. Make sure the area is well vent ilated when
you charge the battery .
.,. Open the engine hood
c::, page 224.
.,. Open the red cover on the posit ive pole
¢fig. 193 .
.,. Connect the charger connectors according to
the instructions to the
jump start bolts.
(Bolts under the red cover= "positive", Bolts
with hex head= "negative").
.,. Only now plug the mains lead for the charg­
ing equipment into the wall outlet and turn
it on
c::, &_ .
.,. Make sure the charging rate is not over
30 amp s/14 .8 Volt.
Checkin g and fillin g 237
.,. When the battery is fully charged: Turn the
charging equipment off and
remove the
mains lead from the wall out let.
.,. Now remove the clamps for the charging
equ ipment.
.,. Close the red cover on the positive pole .
.,. Close the hood
c::, page 225.
A discharged battery can
freeze at tempera­
tures of only
32 F0 (0 °C) . Allow a frozen bat­
tery to thaw completely before attempting to cha rge it
c::, ,&. . However, we recommend not
using a thawed batte ry again because the bat­
tery casing can be cracked due to ice fo rma­
tion and can leak battery ac id.
Battery charging (Maximum charging rate
of 30 amps/14.8 Volt )
When charging at low vo ltages (e.g. with a
trickle charger) , the battery cables do not
have to be disconnected first . The battery
caps should
not be opened when charging a
battery .
It is not necessary to
remove the battery from
the luggage compartment, and it is a lso not
necessary to disconnect the cab les .
Fast charging the battery (charging rate
above 14 .8 Volts)
For technical reasons do not use a battery
charger that uses voltage greater than 14.8
Volts to charge your vehicle's battery .
_& 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 first.
- Do not reuse batteries which were fro­
zen. The battery housing may have
cracked and weakened when the battery
froze.

238 Check ing and filling
- Char ge the bat tery i n a we ll ven tilated
area. Kee p away from open flame or elec­
trical spa rk. Do n ot smoke. Hydrogen gas
generated b y the battery is explosive.
- 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 technicia n w ith the proper equ ip­
ment.
- Battery acid that may spill during charg­ ing should be washed off wit h a solution
of warm water and baking soda to neu­
t rali ze the acid.
(D Note
Never use a fast charger as a booster to
start the engine. This will se riously dam­
age sensitive elect ronic components, such
as control units, relays, rad io, etc., as we ll
as t he battery charger.
Battery replacement
The new battery must have the same specifi­
c ations 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 throughou t your vehicle
qpage 199. The intel ligen t energy manage­
ment system w ill keep the engine battery
charged better than vehicles without th is sys­
tem. To make sure the additional electrical en­
ergy is available once again after you have
changed the battery, we recommend that you
install batteries of the same type and ma nu­
facture only (the same as those installed at
the time your vehicle was delivered). Specifi­
cations a re listed on the battery ho using. Yo ur
author ized de aler must code the b attery in
the energy management system to enable you
to use the energy management fu nctions cor­
rectly after replacing 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 .
- Veh icles with the Start-S top-System * are
equip ped with a spec ial cycle-proof AGM
battery . Install ing a d iffe rent type of
battery can cause problems in the vehi­
cle e lectr ica l system. Whe n replac ing the
vehicle battery, always install one w ith
the same specifications as the origi na l
battery.
@) For the sake of the environment
Because of the prob lem of proper disposal
of a battery, we recomme nd your author­
i zed Audi dealer change the battery fo r
you. Batteri es contain sulfur ic acid and
l ead and must a lways be di spo sed o f prop­
erly in comp liance wi th all envi ronmental
regulations. Disposing of vehi cle batter ies
imprope rly is very dange rous to the envi­
r onment.

Bulbs
Replacing light bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace burned
out 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 appl ies especially to the light bulbs
in the front of your car which you can only
reach through the engine compartment .
Sheet metal and bulb ho lders can have sharp
edges that can cause ser ious cuts, and parts
must be correctly taken apart and then prop­
erly put back together to help prevent break­
age of parts and long term damage from wa­
ter that can enter housings that have not been properly resealed.
F or your safety, we recommend that you have
your authorized Audi dealer replace any bulbs for you, since your dealer has the proper tools,
the correct bu lbs and the expertise .
Gas discharge lamps (Xenon lights):
Fuses and bulbs
Due to the high e lectr ica l voltage, have the
bulbs replaced by a qualified technician.
Head lights w ith Xenon light can be identified
by the high voltage sticker.
LED headlights* require no maintenance.
Please contact your authorized Audi dealer if a
bulb needs to be replaced.
_& WARNING
Contact with high-voltage components of
the electrical system and improper re­
placement of gas discharge (Xenon) head­
light bulbs can cause ser ious personal in­
jury and death .
- Xenon bulbs are pressur ized and can ex­
plode when being changed .
- Changing Xenon lamps requ ires the spe­
cial tra ining, instructions and equip­
ment.
- Only an authorized Audi dealer or other
qualified workshop should change the
bulbs in gas discharge lamps.
&_ WARNING
There are parts with sharp edges on the
openings and on the bulb holders that can
cause serious cuts.
- If you are uncertain about what to do,
have the work performed by an author­
ized Audi dealer or other qualified work­
shop . Serious personal injury may result
from improperly performed work.
(D Tips
-If you still prefer to replace the light
bulbs yourself, be aware that the engine
compartment is a hazardous area to
work in ¢
page 224¢ &.
-It is best to ask your authorized Audi
dealer whenever yo u need to change a
bulb .
