2015 AUDI S3 battery

not used then is being generated in o rder to
maintain an optimal battery charge level.
@ Tips
- Energy management cannot overcome
the laws of physics. Note that the charge l evel and length of the battery life are
limited .
- When the start ing ability is endangered,
the (•) indicator light turns on
c!:>page20.
What you should know
Maintaining the starting ability is the highest
priority.
A lot of stress is p laced on the battery when
driving short distances, in traffic , and at co ld
times of the year. A lot of energy is used but litt le is generated. It is also critical when the
engine is not running but electrical equip­ ment is switched on . In this case, energy is
used but none is generated .
In situations like this, energy management
will actively regulated the distribution of en­ ergy.
Long periods without use
I f you do not drive your vehicle for several
days or weeks, e lectrica l equipment is gradu­
ally sca led back or switched off . This reduces
energy use and ensures the vehicle will be
able to start after long periods of time. Some
conven ience functions such as opening with
the remote contro l key may not be ava ilab le.
These convenience functions will be available
again once you switch the ign ition on and
start the engine.
With the engine switched off For example, if you listen to the radio when
the engine is switched off, the batte ry w ill
drain .

With the engine running
Although electrical energy is generated while driving, the battery can drain. This can happen
when litt le energy is generated, and much is
used and the charge leve l of the battery is not
optimal.
To restore the ba lance of energy, components
that require large amounts of energy are tem­
porari ly scaled back or switched off. Heating
systems in particular require a great deal of energy. If you notice, for example, that the
seat heating* or rear window defroster is not
working, then it has been temporar ily reduced
or switched off . These systems are availab le
again as soon as the energy balance has been
restored.
In add ition, you may notice that the idle
speed has slight ly increased . That is normal
and no cause for concern. Due to the in­
creased idling speed, the additional required
energy w ill be gene rated and the battery will
be charged.
Notice about data
recorded by the Event
Data Recorder and
vehicle control
modules
Event Data Recorder
This vehicle is equipped with an Event Data Recorder ( EDR). The main purpose of an EDR
is to record, in certain crash or near crash-like
situations, such as an airbag deployment or hitting a road obstacle, data that w ill assist in
understanding how a vehicle's systems per­
formed . Th e EDR is designed to record data
related to vehicle dynam ics and safety sys­
tems for a short pe riod of time, typically
30 seconds or less . The EDR in this vehicle is
designed to record such data as:
- How various systems in your veh icle were
operating;
- Whether or not the driver and passenger
safety belts were buckled/fastened;

can reach the catalytic converter . This
could result in overheating of the con­
verter, requ iring its replacement.
- To assure efficient operation of the Emis­
sion Control System :
- Have your veh icle ma inta ined properly
and in accordance with the service rec­
ommendations in your Wa rranty
&
Ma intenance booklet.
- Lac k of proper maintenance as well as
improper use of the vehicle will impa ir
t he funct ion of the emission control
system and cou ld lead to damage.
@) For the sake of the environment
Even when the Emission Cont ro l System is
operating properly, t he exhaus t gas can
have a s ulfu r-like exhaust gas smell unde r
some operating states. This depends on
the s ulfur content of the fue l being used .
Using a different brand of fuel may help,
or filling the tank w ith lead-free super
grade gasoline.
Diesel particulate filter
Applies to vehicles: with d iesel eng ine
The diesel particulate filter fi lters nearly a ll of
the soot part icles out of the exhaust. The fil­
ter cleans itse lf automatically under normal
driving conditions. If the filter cannot clea n it­
self (for examp le, because you are only driving
short d istances) , the fil ter becomes clogged
with soot and the
II symbo l for the diesel
particulate f ilter illum inates ~ page 23.
A WARNING
- Do not park yo ur vehicle ove r flammable
materials such as g rass or leaves because
the high temperature of the diesel par­
t icu late filter could start a fire .
- Do not apply an underbody protectant in
the exhaust system area or a fire could
start.

ma tion about the battery ~ page 228 .
Operate your vehicle
economically and
minimize pollution
General
Your personal style of driving will determine
the economy of your vehicle, as well as ex ­
haust and noise levels .
Fuel economy, env ironme ntal impact, and
wea r on your eng ine, b rakes and tires la rgely
depend on three factors:
- your personal d riving s tyle
- operating conditions
- technical limitat ions
If you ant ic ipate what you need to do next and
drive economically, you can easily cut your
fuel consumpt ion by 10-15 percent. This sec­
tion w ill give you some tips on how you can
help t he env ironment and your pocketbook.
@ Tips
The consumption estimates as published
by ENVIRONME NTAL PROTECTION AGENCY
(EPA) and Transpo rt Canada may not corre­
spond to your actual consumption on the r oad, which will va ry depending upon vehi ­
cle load and speed, ro ad and weather con­
ditions, trip leng th, etc.

Battery
General information
The battery in your Audi does not need any
maintena nce under
normal operating condi­
tions. Aud i recommends having the elect ro­
l yte level check by a n author ized Audi dealer
or author ized Audi Se rv ice Facili ty when there
are
high outside temperat ures or when driving
all day. The e lectrolyte level shou ld a lso be
checked each time the battery is charged
¢ page 230.
Have the batte ry checked when yo u bring your
vehicle in for an inspection . It is a good idea
to replace the battery if it is more than 5 years
o ld.
D uring certain types of airbag deployments,
the battery is disconnected from the vehicle electrical system for safety reasons¢
& in
Repair, care and disposal of the airbags on
page 160.
Di sconnecting the battery te rminals
Some vehicle functions (such as power win ­
dows) are not avai lable when the battery is
disconnected. These functions must be pro­
grammed after the battery is reconnected. To
avo id hav ing to do this, only disconnect the
battery from the vehicle electrical system
when that is necessary to perform repairs .
To reprogram the functions, proceed as fol­
lows:
Function Reprogramming

touch up/down power window ma/-
function functions
Remote control key
If the vehicle does not
or r
eact to the key, it
convenience key must be synchronized
¢ page37
Dig ita l cl ock ¢page 10
ESC indicator light The indicator light
goes out after driving
a few meters
Not running the vehicle for long periods
of time
If you do not drive your vehicle fo r several
days or weeks, electrical components are
gradua lly reduced or switched off. This re­
duces e nergy consumption and maintains the
vehicle's ability to start over a long per iod of
time
¢ page 194. Some convenie nce func­
tions, such as interior lig hting or power seats *
may not work. These convenience functions
will be ava ilable again once you switch the ig-
nition on and start the engine. .,.

Winter operati on
During the winter months, it is common for
the battery capacity to decrease as the tem ­
peratures become lower. This is because more
pow er is n eeded to start the vehicle and com­
ponents such as the headlights and the rear
window defogger are used more frequently.
Avoid using power unnecessarily, especially in
city driving or on short trips . Have your a u­
thorized Audi dealer or authorized Audi Serv­
ice Facility check the battery capac ity before
the start of winter ¢
page 230 . A well-charg­
ed battery will not only reduce starting prob ­
l ems in cold weather, but it wi ll also last lon­
ge r.
A WARNING
- Wor k on the battery requires expert
knowledge. Con tact your au thori zed Audi
dealer q ua lified repai r fac ility for infor ­
mation regarding the vehicle battery.
The re is a risk for chemical burns or ex­
plos ions.
- Never open the vehicle battery. Do not
try to change the battery e lectrolyte lev ­
el. Otherwise explosive gas will escape
from the battery and increase the risk of an exp losion .
@ Tips
If your vehicle is not driven for severa l
weeks in very cold temperatures, remove
the battery and store it in a place where it
w ill no t freeze . This prevents the battery
from being damaged and need ing to be re­
placed.
Working on the battery
Be especially careful when working on or near the battery .
The battery is located in the lugg age compart­
ment under the floor. Before you check any -
