A discharged battery can freeze at temperatures
of only 32 °F (0 °C). Allow a frozen battery to
thaw comp letely before attempting to charge it
9 & . However, we recommend not using a
thawed batte ry agai n because the batte ry casing
can be cracked due to ice forma tion a nd ca n leak
battery a cid.
Battery charging (Maximum charging rate of
30 amps /14.8 Volt )
When charging at low voltages (e.g. w ith a trickle
c harger ),
the battery cab les do not have to be
d isconnected first. The batte ry caps sho uld
not
be opened when charging a battery.
It is not necess ary to remove the ba tte ry from
t he luggage compa rtment.
Fast charging the battery (charging rate
above 14.8 Volts)
F or technica l reasons do no t use a ba ttery charg­
e r that uses voltage grea ter than 14.8 Vol ts to
charge your vehicle's battery .
A WARNING
Charging a battery can be dangerous.
- Always fo llow the operating instructions
provide d by the batte ry charge r manufactur ­
er when c harging your battery.
Checking and Fillin g
-Never charge a frozen battery. It may ex­
plode because of gas trapped in the ice . Al­
low a frozen battery to thaw out first.
- Do not reuse batteries wh ich were frozen.
The battery housing may have cracked and
weakened whe n the battery froze.
- Charge the battery in a well ventilated area.
K eep away from open flame or electrical
spark. Do not smoke. Hydrogen gas gene rat­
ed by the ba tte ry is explosiv e.
- To reduce the danger of explosion, never
connect or d iscon nect charger cab les wh ile
the charge r is operating.
- Fast cha rging a batte ry is dange rous and
should only be at tempted by a compe tent
technicia n w it h the proper eq uipment.
- Battery acid that may sp ill dur ing cha rging
should be washed
off with a solut io n of
warm water and baking soda to neutralize the a cid .
@ Note
Neve r use a fast charger as a booster to start
the e ng ine . T his w ill ser iously damage sensi­
tive elec tronic components, s uch as co ntrol
units , relays, radio, etc. , as we ll as the battery
cha rger.
Battery replacement
The new battery must have the same specifica­
tions and dimensions as the original equipmen t
battery.
Intelligent energy management in your vehicle is
r esponsible for distributi ng the elect rical energy
t hr ough out your veh icle
9 page 175. T he intelli ­
gen t energy management sys tem w ill keep the
engi ne battery cha rged better then vehicles with ­
out this system . To make s ure t he addit iona l elec­
trical energy is avai lab le once again after yo u
have changed the battery, we recommend that
you install bat teries of the same type and manu­
facture on ly (the same as those installed at the
t ime you r vehicle was del ivered) . Specificat ions
are listed on the battery hous ing . You r autho r­
i z ed Audi dea ler m ust code t he battery in the en-
ergy ma nagement system to en able you to use .,,.

Checking and Fill in g
th e e nergy management functions correctly after
replacing the battery.
If i t is not poss ible to use a battery of this type,
the new battery must have the same capacity,
voltage (12-vo lts), amperage, construct ion and
p lug sealing.
When insta lling the battery, make sure the igni­
tion and all elec trical consumers are t urned off.
CD Note
Make sure the ventilation hose on the s ide of
t he batte ry is connected, otherwise fumes or
bat tery ac id can leak out.
@ For the sake of the environment
Because of the problem of proper d isposa l of
a battery, we recommend your author ized
Audi dea le r change the battery for yo u. Ba t­
teries contain su lfuric acid and lead and must
always be disposed of properly in compliance
w ith all environmenta l reg ulations. D isposing
of vehicle batteries improperly is very danger­
ous to the environment.

Tires and vehicle load limits
There are limits to the amount of load or weight that any vehicle
and any tire can carry. A vehicle
that is overloaded will not handle
well and is more difficult to stop.
Overloading can not only lead to
loss of vehicle control, but can al­
so damage important parts of the
vehicle and can lead to sudden tire failure,
including a blowout
and sudden deflation that can
cause the vehicle to crash.
Your safety and that of your pas­
sengers also depends on making
sure that load limits are not ex­
ceeded. Vehicle load includes ev­
erybody and everything in and on
the vehicle. These load limits are
technically referred to as the vehi­ cle's
Gross Vehicle Weight Rating
("GVWR").
The "GVWR" includes the weight
of the basic vehicle, all factory in­
stalled accessories, a full tank of
fuel, oil, coolant and other fluids ""

Bulbs
Replacing bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace any bulbs for
you .
It is becoming increasingly more and more diffi­
cult to replace vehicle light bulbs since in many
cases , other parts of the car must first be re­
moved before you are ab le to get to the bulb .
This applies especially to the light bulbs in the
front of you r ca r which you can only reach
through the engine compartment .
Sheet metal and bulb holders can have sharp
edges that can cause ser ious cuts, parts must be
Fuses and bulbs
correct ly taken apart and then properly put back
together to help prevent breakage of parts and
long term damage from water that can enter
housings that have not been properly resealed.
For your safety, we recommend that you have
your authorized Audi dea ler replace any bulbs for
you, since your dealer has the proper tools, the
correct bulbs and the expertise.
Gas discharge lamp s (Xenon lights)*:
Due to the high electr ical voltage, have the bulbs
replaced by a qualified technician . Head lights
with Xenon light are identified by the high volt­
age sticker.
A WARNING
Changing Xenon lamps without the necessary
equipment can cause serious personal injury.
- Bulbs are pressurized and can explode when
being changed . Potential risk of injury!
- On vehicles equipped with gas discharge
bu lbs (Xenon light) * life -threatening injuries
can result from improper handling of the
high -vo ltage portions of such lamps!
-On ly your authorized Audi dealer or quali­
fied workshop shou ld change the bulbs in
gas discharge lamps. 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 wor k performed by an autho rized Audi
dealer or qualified workshop. Serious per­
sonal injury may result from improperly per­
formed work .
(D Tips
-If you st ill prefer to replace the light bulbs
yourself, be aware that the eng ine compart­
ment is a hazardous area to work
inq page191 q&_ ,
-It is best to ask your authorized Audi dealer
whenever you want to change a bulb.
