220 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 d uring 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.
In tell igent energy management in your veh i­
cle is respons ible for d istributing the e lectr i­
cal energy throughout you r vehicle
~ page 185. 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. You r
author ized Audi dealer must code the battery
in the ene rgy managemen t system to enable
you to use the ene rgy 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 ventilat ion 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 fo r
you. Batteries contain sulfur ic acid and
l ead and must always be disposed of prop­
erly in comp liance with all environmental
regula tions. Dispos ing of veh icle batter ies
i mprope rly is very dange rous to the envi­
r o nment .

w all.
The correct tire pressure for the spare wheel is
l ocated on a label on the driver's side B-pillar.
Because technical changes may be made to
vehicle equipment during the model year, a l­
ways compare the tire size designation on the
tire pressure label on your vehicle with the
tires on your vehicle. Make sure that the tire
size information on the vehicle label is the
same as the size of the t ires on the vehicle.
This is especially important if the vehicle be­
l ongs to someone else or you bought the ve hi- cle w
ith different rims/tires or you bought the
vehicle as a previously owned vehicle .
Remember, your safety and that of your pas ­
sengers also depends on making sure that
l oad lim its are not exceeded. Vehicle load in ­
cludes everybody and everything in and on the
vehicle. These load limits are technically refer­
red to as the veh icle's Gross Vehicle Weight
Rat ing ("GVWR"). The Gross Axle We ight Rat­
ing ("GAWR") is the maximum load that can
be applied at each of the vehicle's two ax les .

24 4 What do I do no w?
There are some restrictions on the use of the
compact spare tire. The compact spare tire
has been des igned specifically for your type of
vehicle.
It must not be swapped with a com­
pact spare tire from another type of vehicle.
Sno w cha in s
For technical reasons, the use of snow chains
on the compact spare tire is
n ot permitted .
If you do have to dr ive with snow cha ins and a
front tire fails, mount the spare wheel w ith
tire instead of a rear tire. Install the snow
chains on the rear tire and use it to rep lace
the defective front tire.
A WARNING
- Never use the spare tire if it is damaged
or if it is worn down to the tread wear in­
dicators.
- If the spare tire is more than 6 years o ld,
use it only in an emergency and w ith ex­
t reme caution and careful driving.
- The spare tire is intended only for tem­
porary and short-term use. It should be
replaced as soon as possib le w ith the
normal wheel and t ire.
- After mounting the compact spare tire, the tire pressu re must be checked as
soon as poss ible. The tire pressure of the
c ompac t spare tire must be 4.2 bar; oth­
erwise, you risk hav ing an accident.
- Do not drive faster than 50 mph (80 km/
h). You risk having an acc ident.
- Avoid full-throttle acce le rat ion, heavy
braking, and fast corner ing . Yo u risk hav­

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!
