Battery
General information
Your vehicle is equipped with a special bat
tery, an
ACM battery. This battery is located
in the luggage compartment and must be re
p laced w ith an original equipment battery .
Under normal operati ng conditions, the bat
tery is
maint enan ce -fre e.
Have the battery checked when you take your
ve hicle in for service. You are well adv ised to
replace a battery that is older than
5 years.
Di sconn ect ing the battery terminal s
Some vehicle functions (power window regu
lators, for example) are lost if the battery ter
minals are d isconnected. These functions have
to be re learned after the battery terminals are
connected again . To prevent this, the battery
should only be d isconnected from the vehicle
e lectr ica l system when absolutely necessary
for repairs .
Vehicles not driven for l ong period s
If you do not drive your vehicle over a period
of several days or weeks, electrical compo
nents are gradually cut back o r switched off .
This reduces energy consumption and main
tains sta rting capab ility over a longer per iod
c::> page 146. Some of the convenience func
tions may not operate, s uch as the interior
lights or power seat adjustment. The conven
ience functions will be avai lab le again when
you switch on the ignition and start the en g ine.
Winter operation
D uring the winter months, ba tte ry capaci ty
tends to decrease as temperatures d rop. This
is because more powe r is also consumed while
Checkin g and fillin g 175
starting, and the headlights, rear window de
fogger, etc ., are used more often .
Avoid unnecess ary powe r consumpt io n, p ar
t icu lar ly in city traffic o r when traveling only
sho rt distances. Let your authorized A udi
dealer check the capacity of the vehicle bat
tery before winter sets in
c::> page 178. A well
charged battery will not on ly prevent starting
problems when the weather is cold, but will
also last longer .
Replacing battery
The new battery must ha ve the same capaci
ty, voltage (12 volts), amperage, construction
and plug sea ling, as the original battery. Spec
ifications are listed o n the battery housing.
Batter ies spec ia lly developed by Audi fulfill
the maintenance, outp ut, and safety require
ments.
When installing the battery, make sure the ig nition and a ll electrical consumers are switch
ed off
c::> (D .
We recommend that you use maintenance
free or
cycle -res istant /leak-proof batter ies
accord ing to the standards TL 825 06 (from
Apr il 2008) and VW 7 50 73 (from Ap ril
2010).
Rep lacing the battery should be carried by a
qualified workshop. Please fo llow the instruc
tions on the battery cover.
([) Note
-All work on the battery requ ires techn i
cal know ledge. P lease contact an Audi
