A discharged battery can fre eze at temperatures
of only 32 F
0 (0 °C). A llow a frozen battery to
thaw comp lete ly before attempt ing to charge it
¢ ,&. However, we recommend not using a
thawed battery again because the battery casing
can be cracked due to ice formation and can leak
battery acid.
Battery chargin g (Ma ximum cha rging rate of
30 amp s/14 .8 Volt )
When charging at low voltages (e.g. with a trick
le cha rger ),
the battery cables do not have to be
d isconnected first. The battery caps should
not
be opened when charging a battery .
It is not necessary to remove the battery from
the luggage compartment, and it is also not nec
essary to disconnect the cables.
Check ing and Filling
Fast charging the batt ery (charging rate
ab ove 14.8 Volt )
For technical reasons do not use a battery charg
er that uses vo ltage greater than 14.8 Volt 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 .
- Never charge a frozen battery. It may ex
plode because of gas trapped in the ice. Al
low a froze n battery to thaw out first .
- Do not reuse batter ies 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 d isconnect charge r cables while
the charger is ope rating .
- Fast charg ing a battery is dangerous and
should only be attempted by a competent
technicia n w ith the prope r equipment.
- Batte ry acid that may spill during charging
should be washed off w ith a so lution of
warm water and baking soda to neutra lize
t he acid .
{[) Note
Never use a fast charger as a booster to start
the e ngine. This will se riously damage sensi
tive electronic components, such as control
units, re lays, radio, etc., as well as the bat tery
charge r.
Battery replacement
The new battery must have the same specifica
tions and dimensions as the original equipment
battery .

Check ing and F illing
througho ut your vehicle ¢ page 186 . The intelli
gent energy management system wi ll keep the
engine battery charged better than veh icles with
out this system . To make sure the addit ional
electrical energy is avai lab le once again after you
have changed the battery, we recommend that
you install batter ies of t he same type and manu
facture on ly (the same as those insta lled at the
time your veh icle was delive red). Spec ificat ions
are listed on t he b attery housing. Your author
i z ed dealer must code the battery in the energy
management system to enable you to use the en
ergy manag ement functions correctly after re
p lacing the battery.
The new battery must have the same capac ity,
voltage (12 -vo lt), amperage, const ruction and
p lug sealing .
W hen insta lling the ba tte ry, make sure the igni
tion and all elec trical consumers are sw itched

@) For the sake of the environment
Because of the prob lem of pr oper disposal of
a ba ttery, we recommen d your au thor ized
Audi dea le r change the battery fo r you. Bat
teries contain su lf u ric acid and lea d and must
always be disposed o f prope rly in comp liance

Checking service intervals
You can check the remaining distance or time un

Resetting the indicator
Your authorized Audi dealer or authorized Audi
Service Facility will reset the service interval dis
p lay after performing service.
I f you have changed the oil you rself, you must re
set the oil change interval.
To reset the indicator, select: the

- Following the service inte rvals is critical to
maintain ing the service life and va lue of
your vehicle, especially the engine . Even if
the mileage on the vehicle is low, do not ex

Wheels and Ti res
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.
.,.Mark 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 N ote
-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
218
and b raking 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.
