thaw completely before a ttempting to charge it
¢ & . However, we recommend not using a
thawed battery aga in beca use the battery casing
can be cracked due to ice formation and can leak
battery ac id .
Battery charging (Maximum charging rate of
30 amps /14 .8 V olt)
When charging at /ow voltages (e.g. w ith a t ric k­
le charge r),
the battery cables do not have to be
disco nnected f irst . The battery caps should
not
be opened when charging a battery .
It is not necessa ry to remove the battery from
the luggage compartment.
Fa st charging the batt ery (cha rging rate
above 14 .8 Volt s)
For technical reasons do not use a battery charg­
er that uses vo ltage greater than 14.8 Volts to
charge your veh icle's battery .
A WARNING
-
Charging a battery can be dange rous.
- Always follow the operating instructions
provided by t he battery cha rge r manufactur­
er when charging yo ur battery .
- Never charge a frozen battery. It may ex­
p lode because of gas trapped in the ice. Al­
low a froze n battery to thaw out first .
- Do not reuse batteries which were frozen .
The batte ry hous ing may have c racked and
weakened when the battery froze .
- Charge the battery in a well ve ntilated area .
Keep away from open flame or electrical
spa rk. Do not smoke . Hydrogen gas generat­
ed by the batte ry is explos ive.
- To reduce the danger of exp losion, never
connect or d isconnect charge r cables while
t he charger is ope ra ting.
- F ast charg ing a battery is d ange rous and
should only be at tempted by a competen t
technici an with the prope r equipmen t.
- Ba ttery a cid that may spill duri ng cha rging
should be washe d off w it h a so lution of
warm water and baking soda to neutra lize
the acid.

Check ing and F illing
CJ) Note
Never use a fast charger as a booster to start
the engine . This will serious ly damage sensi­
tive electronic components, such as control
units, relays, radio, etc., as well as the battery
charger.
Battery replacement
The new battery must have the same specifica­
tions and dimensions as the original equipment
battery .
Intelligent energy management in your vehicle is
responsible for distributing the electrical energy
throughout your vehicle
¢ page 157. The intelli ­
gent energy management system wi ll keep the
engine battery charged better then veh icles w ith­
out this system. To make sure the addit ional
e lectrica l energy 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
time your veh icle was delivered). Specifications
are listed on the battery housing. Your author­
ized Audi dealer must code the battery in the en­
ergy management system to enable you to use
the energy manageme nt functions correctly after
replacing the battery.
If it is not possible to use a battery of this type,
the new battery must have the same capacity,
voltage (12-volts), amperage, construction and p lug sealing.
When installing the battery, make sure the igni­
tion and all electrical consumers are turned off.
@ Note
Make sure the ventilation hose on the side of
the battery is connected, otherw ise fumes or
battery acid can leak out.
@ For the sake of the environment
Because of the problem of proper disposal of
a battery, we recommend your authorized
Audi dea ler change the battery for you. Bat­
teries contain sulfuric ac id and lead and must
always be disposed of properly in compliance
190
with all environmenta l regulations. Disposing
of vehicle batteries improperly is very danger­
ous to the environment.

To reduce the risk of lime scale depos its on the
spray nozzles, use clean water with low amounts
of calcium . Always add window cleaner to the wa­
ter. When the outside temperatures are cold, an
anti-freez ing agent shou ld be added to t he water
so that it does not freeze .
(D Note
-The concentration of anti-freezing agent
must be adjusted to the vehicle operating
conditions in the respective climate. A con­
centration that is too high can lead to vehi­
cle damage.
- Never add radiator anti-freeze or other addi­
t ives to the washer fluid.
- Do not use a glass cleaner that contains
paint solvents, because th is could damage
the paint.

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 Rat­
ing
("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
plus maximum load. The maxi­
mum load includes the number of
passengers that the vehicle is in­
tended to carry ("seating capaci­
ty") with an assumed weight of
150 lbs. (68 kg) for each passen-
ger at a designated seating

Emergency assistance
General information
.. Park the vehicle as far as poss ible from moving
traffic in the event of a flat tire. In the event of
a flat tire, park the vehicle on a level surface. It
you are on a steep incline, be especially careful.
.. Set the parking brake .
.. Switch the emergency flashe rs on .
.. Put on a reflective vest, if available .
.. Set up the warn ing triang le, if available .

your protection and the for the safety of other drivers.
_& WARNING
Improper use of the vehicle jack can cause se ­
rious personal injuries.
- Never use the screw driver hex head to
t ighten whee l bolts, since the bolts cannot
attain the necessary tighten ing torque if you
use the hex head, potentially causing an ac­
c ident.
- The factory-supplied jack is intended only
for your vehicle model. Under no circum­
stances should it be used to lift heavy
vehicles o r other loads; yo u ris k inju ring
yo urself.

Bulbs
Replacing light 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 m ust first be re­
moved before you are able to get to the bulb .
T his applies especially to the light bulbs in the
front of your car which you can only reach
through the engine compartment .
Sheet metal and bu lb holders can have sharp
edges that can cause serious cuts, pa rts must be
correctly taken apart and then properly put back
together to help prevent breakage o f parts and
long term damage from water that can enter
housings that have not been properly resealed.
For your safety, we recommend t hat you have
your authorized Aud i dea le r rep lace any bulbs fo r
you, since your dealer has the proper tools, the
correct bulbs and the expertise.
Gas di schar ge la mps (Xe no n light s):
Due to the high electr ical voltage, have the bulbs
rep laced by a qualified technician. Headlights
with Xenon light are identified by the hig h volt­
age st icker.
LED headlights* require no maintenance . Please
contact your authorized Audi dea ler if a bulb
needs to be replaced.
_&. WARNING
Changing Xenon lamps wi thout the necessary
equipment can cause serious personal injury .
- Bulbs are pressu rized and can explode when
be ing changed. Potent ial ris k of injury!
- On veh icles equipped with gas disc harge
bu lbs (Xenon light) life-threatening injuries
can resu lt from improper handling of the
high-vo ltage portions of such lamps!
- Only your authorized A udi dealer or quali­
fied workshop sho uld change the bulbs in
gas discharge lamps. There are parts with
sharp edges on the openings and on the
