of only 32 °F (0 °C) . A llow a frozen batte ry to
Checking and Filling
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.

The washer fluid reservoir O contains the wind­
shield washer flui d¢

ervoir capacity is found in
¢ page 230.
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.

Wheels and Tires
General information
.,.Check your tires regularly for
damage (punctures, cuts, cracks
and bulges). Remove foreign ob­
jects from the tire tread.
.,. If driving over curbs or similar
obstacles, drive slowly and ap­
proach the curb at an angle.
.,.Have faulty tires or rims re­
placed immediately.
"'Protect your tires from oil,
grease and fuel.
.,.M ark tires before removing
them so that the same running
direction can be maintained if
they are reinstalled.
"'Lay tires flat when storing and
store them in a cool, dry location
with as little exposure to light as
possible.
(D Note
-Please note that summer and
winter tires are designed for
the conditions that are typical in those seasons. Audi recom­
mends using winter tires dur­
ing the winter months. Low
temperatures significantly de­ crease the elasticity of summ­
er tires, which affects traction
Wheels
and braking ability. If summer
tires are used in very cold
temperatures, cracks can form
on the tread bars, resulting in
permanent tire damage that
can cause loud driving noise
and unbalanced tires.
-Burnished, polished or
chromed rims must not be
used in winter driving condi­
tions. The surface of the rims
does not have sufficient corro­
sion protection for this and
could be permanently dam­ aged by road salt or similar
substances.

New tires or wheels
Audi recommends having all work
on tires or wheels performed by
an authorized Audi dealer or au­
thorized Audi Service Facility.
These facilities have the proper knowledge and are equipped with
the required tools and replace­
ment parts.
.,.New tires do not yet have the
optimum adhesion properties. Drive carefully and at moderate
speeds for the first 350 miles (500 km) with new tires .
.,.Use tires of the same construc­
tion, size (rolling circumference)
and as close to the same tread
pattern as possible on all four
wheels .
198
.,.Do not replace tires individually.
At least replace both tires on the
same axle at the same time.
.,.Audi recommends that you use
Audi Original equipment tires. If
you would like to use different
tires, please note that the tires may perform differently even if
they are the same size ¢
,&.
.,. If you would like to equip your
vehicle with a tire/rim combina­
tion that is different from what
was installed at the factory, con­
sult with an authorized Audi dealer or authorized Audi Service
Facility before making a pur­
chase ¢&, .
If the spare tire is different from
the regular tires installed on the
vehicle -for example, if winter
tires or wide tires are installed -
then only use the spare tire tem­
porarily in case of emergency and
drive carefully while it is in use. It
should be replaced with a regular
tire as soon as possible.
On
all wheel drive vehicles, all
four wheels must be equipped
with tires that are the same brand and have the same construction
and tread pattern so that the
drive system is not damaged by .,.
