A discharged battery can freez e at temperatures
of only 32 °F (0 °C) . Allow a frozen battery to
thaw completely before attempt ing to charge it
~ _& . However, we recommend not us ing a
thawed batte ry again because the battery casing
can be cracked due to ice format ion and can leak
battery acid.
Battery charg ing (Maximum charging rate of
30 amps /14.8 Volt )
When cha rging at low vo ltages (e .g . with a tric k­
l e char ger ),
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 batte ry from
the luggage compartme nt.
F a st cha rging the battery (charg ing rate
above 14.8 Volt s)
For techn ical reasons do not use a battery charg­
e r that uses voltage greate r than 14 .8 Volts to
charge your vehicle 's battery.
A WARNING
Charging a battery can be dangerous .
- Always follow the operating instructions
provided by the battery charger manufactur­
er when charging your battery .
Check ing and Filling
-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 which were frozen.
The battery hous ing may have cracked and
weakened when the battery froze.
- Charge the battery in a well ventilated area. Keep away from open flame or electrical
spark. Do not smoke . Hydrogen gas generat­
ed by the battery is explos ive.
- To reduce the danger of explosion, never
connect or disconnect charger cables while
the charger is operating .
- Fast charg ing a battery is dangerous and
should only be attempted by a competent
technician w ith the proper equipment.
- Battery acid that may spill during charging should be washed off w ith a solution of
warm water and baking soda to neutralize
the acid .
@ Note
Never use a fast charger as a booster to start
the engine . This will seriously damage sensi­
tive electronic components, such as control units, re lays, radio, etc., as well as the battery
cha rge r.
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
r esponsib le for distr ibut ing the e lectrical energy
t hr oughou t your vehicle ~
page 182. The intelli­
gent energy management system will keep the
engine battery charged better then vehicles with ­
out this system. To make sure the additional
electrical 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
t ime your vehicle was delivered) . Specifications
are listed on the battery housing . Your author­
ized Audi dealer must code the battery in the en-
ergy managemen t system to enable you to use
ll>

Checking and Filling
the energy m anag ement functions correctly after
replacing the battery.
I f it is not poss ible to use a battery of th is type,
the new battery must have the same capacity,
voltage (12 -volts), amperage, construction and
p lug sealing .
When insta lling the batte ry, make sure the igni­
tion and all elec trical consumers are turned off.
CD Note
Ma ke sure the ventilation hose on the side of
t he batte ry is connected, othe rw ise f umes or
bat tery acid can lea k out.
@ For the sake of the environment
Because of the prob lem of proper dispo sal of
a ba tte ry, we recommen d your author ized
Audi de aler change the battery fo r you . Bat­
teries contain su lf u ric acid and lea d and must
always be disposed of properly in compliance
w ith all environmental regu lations. D ispos ing
of vehicle batteries improperly is very danger­
ous to the env ironment.

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.
