&
Battery acid is high ly corrosive. Always
wea r protect ive g loves and eye protect ion .
.
®
Fire, spa rks, open flame and smoking are
forbidden .
A
A highly exp losive mixt ure of gases can
form when charging ba tte ries.
®
Always keep children far away from bat-
tery electrolyte and the battery .
~
Always follow the instructions in the oper -
ating manual.
A WARNING
All work on the battery or electrical system in
your vehicle can result in injuries, chemical burns, accidents or burns. Because of this, all

Requirement: only use chargers with a ma ximum
charging current of 30 amp s/14.8 Volt s.
The ve­
hicle battery cab les remain connected.
Depend ing on the engine, the battery is located
in the engine compartment or i n the l uggage
compartment. For vehicles w ith the battery in
the luggage compartment, a jump start point
that is also used for battery charg ing is located i n
the engine compartment . The battery is a lways

Check ing and F illing
~ Applies to: vehicles with the vehicle battery in
the engine compartment: open the battery cov­
er
¢ fig. 272 .
~ Applies to: vehicles with jump start point(+):
open the cover on the posi tive term inal
¢ fig . 273 .
~ Clamp the charger terminal clamps as instruct­
ed on the
p os itiv e t erminal (+ ) and only on the
bo dy ground p oin t(-).
~ Inse rt the powe r cable for the charg ing device
into the socket and switch the device on.
~ At the end of the charging process, switch the
charger off and pull the power cab le out of the
socket.
~ Remove the charger terminal clamps.
~ Applies to: vehicles with the vehicle battery in
the engine compartment: fold the cover back
on the battery correctly .
~ Applies to: vehicles with jump start point(+):
close t he cover on the positive term inal.
~ Close the hood ¢ page 320.
A WARNING
-A highly exp losive mixture of gases can form
when charging batteries . On ly charge the
vehicle battery in well -venti lated areas.
- A drained vehicle battery can freeze at tem ­
peratures around 32
QF (0 QC). A frozen or
thawed vehicle battery must not be charged
and must not be used anymore. If ice forms,
the battery housing can crack and battery electrolyte can leak out, which increases the
risk of a n explos ion and chemical burns .
Contact an autho rized Aud i deale r or au ­
tho rized Aud i Serv ice Facility fo r more info r­
mation .
-Do not connect o r disconne ct the c ha rg ing
cable while charg ing beca use th is increases
the risk of an exp losion.
(D Tips
-Only charge the vehicle battery through the
con nections in t he e ng ine compartment.
-Read all of the manufacture r's instructions
fo r th e cha rger befo re charg ing t he ve hicle
battery.

To reduce the risk of lime scale depos its on the
sp ray nozzles, use clean water with low amounts
of calcium . Always add w indow cleaner to the wa­
ter . When the outside temperatures are cold , an
ant i-freez ing agent sho uld be added to t he wate r
so that it does no t freeze.
@ Note
-Th e concentration of ant i-freez ing agent
must be adjusted to t he ve hicle operat ing
c ondi tions i n the respective clima te . A con ­
centration t hat is too high can lead to vehi ­
cle damage .
-Never add radia to r an ti- free ze o r o ther ad di­
t ives to the washer fluid.
-Do not use a glass clea ner th at conta ins
paint so lvents, because t his could damage
the paint.
Service interval display
The service interval display detects when your ve ­
hicle is due for service .
The service interval display works in two stages: .,.

-Inspection or oil change reminder: after a cer ­
tain distance driven, a message appears in the i nst rument cluste r display each time the ign i­

tance or time is displayed briefly .
-Inspection or oil change due: if your vehicle

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.
_&. WARNING -
-Never drive faster than the maximum permitted speed
for your tires. This could cause
the tires to heat up too much.
This increases the risk of an
accident because it can cause
the tire to burst .
-Always adapt your driving to the road and traffic condi-
330
tions . Drive carefully and re­
duce your speed on icy or slip­
pery roads . Even winter tires
can lose traction on black ice.
(@ Note
-Please note that summer and
winter tires are designed for
the conditions that are typical
i n those seasons . Aud i recom­
mends using winter tires dur­
ing the winter months . Low
temperatures significantly de­
crease the elasticity of summ­
er tires, which affects traction
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
t ions. The surface of the r ims
does not have sufficient corro­
sion protection for this and
could be permanently dam ­
aged by road salt or similar
substances.
