2012 AUDI A5 COUPE battery capacity

248 Checking and filling
Have the battery checked when you take your
ve hicle in for service. Yo u are well advised to
replace a battery that is older than 5 years .
W ith certa in types o f airbag deployment, the
battery is d isconnected from the vehicle elec ­
trica l system for safety reasons ¢
& in Re­
pair, core and disposal of the airbags on
page 176.
Disconnecting the battery terminals
Some veh icle func tions (power w indow regu­
l a tors, for example) are los t if the bat tery ter ­
minals a re disconnected . These functions have
to be re learned after the battery terminals a re
connected agai n. To prevent this, the battery
should only be disconnected from the vehicle
e lectrical system whe n absolutely necessary
for repairs .
Vehicles not driven for long period s
If you do not drive your vehicle over a period
of several days or weeks, electrical compo­ n ents are gradually cut back o r switched off.
This reduces energy consumption and main ­
tains starting capab il ity over a longer period
¢ pag e 211.
Some of the conven ience functions may not
operate, such as the inter ior lights or the
power seat adjustm ent. The conven ience
f u nctions w ill be ava ilable again when you
turn on the igni tion and st art the eng ine.
Winter operation
During the winter months, battery capacity
tends to decrease as tempe rat ures d rop . This
i s becaus e more powe r is also consumed while
start ing , a nd the headligh ts, rea r window de­
f o gger, etc., are used more o ften .
Avoid unnec essary power consumption, par­
ticular ly in c ity traffic or w hen t rave ling o nly
short d istances. Let you r auth o riz ed Audi
d ea le r che ck t he cap acity of the ve hicl e bat­
tery be fore w inte r se ts in
¢ page 250. A we ll
cha rged batte ry w ill not only prevent sta rting
p ro bl ems when the weathe r is cold, but wi ll
a ls o l ast longer.
(D Tips
If your vehicle is left stan ding for seve ral
weeks at e xtremely low temperatures, the
vehicle battery sho uld be removed and
st ored w here it w ill n ot freeze . This will
p revent it from be ing damaged and having
to be replace d.

_& WARNING
Wh eneve r workin g on th e ba ttery o r o n
the elec trical system, there is t he ris k of
in jury, accident and even fi re . Read and
h eed the followin g WAR NINGS:
-

CD Note
Never use a fast charger as a booster to
start the engine. This will seriously dam­
age sensitive electronic components, such
as control units, relays, radio, etc., as well
as the battery charger.
Battery replacement
The new battery must have the same specifi­
cations and dimensions as the original equip­
ment battery.
Intelligent energy management in your vehi­
cle is responsible for distributing the electri­
cal energy throughout your vehicle
c::, page 211. The intelligent energy manage­
ment system w ill keep the engine battery
charged bette r then ve hicles w ithout this sys­
tem. To ma ke sure t he addi tional e lectrical en­
ergy is available once again after you have
changed the battery, we recommend that you
install batteries of the same type and man u­
facture only (the same as those installed at
the time your vehicle was delivered). Specifi­
cations are listed on the battery housing. Your
author ized Audi dealer must code the battery
i n the energy management system to enable
you to use the energy management functions
correctly after replac ing the bat tery .
If it is not possible to use a battery of this
type, the new battery must have the same ca­ pac ity, voltage (12 volts), amperage, con­
s truction and pl ug seal ing .
When insta lli ng the battery, make sure the ig ­
ni tion and all e lectr ica l cons umers are turned
off.
(0 Note
Ma ke sure the venti lation hose on the s ide
of the battery is connected, othe rwis e
fumes or battery ac id can leak out.
@ For the sake of the environment
Because of the problem of proper d isposa l
of a batte ry, we recommend your author­
ize d Au di dealer change th e batte ry for

Emergency situations
General
This chapter is intended for trained emer­
gency crews and working personnel who
have the necessary tools and equipment to perform these operations.
Starting by pushing or
towing
Q;) Note
Vehicles with an automatic transmission
cannot be started by pushing or towing.
Starting with jumper
cables
If necessary , the engine can be started by
connecting it to the battery of another vehi­
cle.
If the engine should fail to start because of a
discharged or weak battery, the battery can be
connected to the battery of
another vehicle,
using a
pair of jumper cables to start the en­
gine .
Jumper cables
Use only jumper cables of sufficiently
large cross section to carry the starter current
safely. Refer to the manufacturer's specifica­
ti ons.
Use only jumper cables with
insulated termi­
nal clamps which are distinctly marked :
plus(+) cable in most cases colored red
minus (-) cable
in most cases colored black .
A WARNING
Batteries contain electricity, acid, and gas.
Any of these can cause very serious or fatal
injury. Follow the instructions below for
safe handling of your vehicle's battery.
- Always shield your eyes and avoid lean­
ing over the battery whenever possible. -
A discharged battery can freeze at tem­
peratures just below
32 °F (0 °(). Before
connecting a jumper cable, you must
thaw the frozen battery completely, oth­
erwise it could explode.
- Do not allow battery acid to contact eyes
or skin . Flush any contacted area with
water immediately .
- Improper use of a booster battery to
start a vehicle may cause an explosion.
- Vehicle batteries generate explosive gas­
es . Keep sparks, flame and lighted ciga­
rettes away from batteries .
- Do not try to jump start any vehicle with
a low acid level in the battery .
- The voltage of the booster battery must
also have a 12-Volt rating. The capacity
(Ah) of the booster battery should not be
lower than that of the discharged bat­
tery . Use of batteries of different voltage
or substantially different "Ah" rating
may cause an explosion and personal in­
jury.
- Never charge a frozen battery. Gas trap­
ped in the ice may cause an explosion.
- Never charge or use a battery that has
been frozen. The battery case may have
be weakened.
- Use of batteries of different voltage or
substantially different capacity (Ah) rat­
ing may cause an explosion and injury.
The capacity (Ah) of the booster battery
should not be lower than that of the dis­
charged battery.
- Before you check anything in the engine
compartment, always read and heed all
WARNINGS¢
page 230, Engine com­
partment.
@ Note
- Applying a higher voltage booster bat­
tery will cause expensive damage to sen­
sitive electronic components, such as
control units, relays, radio, etc.
- There must be no electrical contact be­
tween the vehicles as otherwise current
could already start to flow as soon as the
positive(+) terminals are connected. ..,.
