2015 AUDI S3 battery capacity

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 -
"' N thing in the luggage compartment, read and 0
iii heed all WARNINGS ¢ _&.
Checking and Fillin g 229
Always heed the safety warning s, when work­
ing on the vehicle battery or the vehicle e lec­
trical system to prevent in jury.
The following WARNINGS are very
important wh en working on the batte ry :

A WARNING
Whenever working on the battery o r on
the elect rical system, there is the risk of
injury, accident and even fire. Read and
heed the following WARNINGS :
- Always wear eye protection. Do not let
-
battery ac id or any lead particles get on
your skin or clothing. Shield your eyes.
Exp losive gases can cause blindness or
other inju ry.
- Battery acid conta ins sulfuric acid. Sulfu­
ric acid can cause blindness and severe
bu rns.
- Always wear g loves and eye protection.
Do not tilt the battery because acid
could leak out of the ventilat ion open­
i ngs.
- If you get battery aci d in your eyes or
on your skin, immediately rinse with
cold water for several minutes and get med ica l attent ion.
- If you should ingest any battery acid,
seek medical attention immediately . •

the time your vehicle was delivered) . Specifi­
cations are listed on the battery housing. Yo ur
author ized dealer must code the battery in
the energy management system to enable you
to use the energy management functions cor­ rectly after replac ing the battery .
The new battery must have the same capacity,
voltage (12-volts), amperage, construct ion
and plug sealing.
When insta lling the battery, make sure the ig­
n ition and all e lectr ica l consumers are sw itch­
ed off.
Make sure the venti lation hose on the side
of the battery is connected, otherwise
fumes or battery ac id can leak out.
@ For the sake of the environment
Because of the problem of proper disposa l
of a battery, we recommend your author­
ized Audi dealer change the battery for
you. Batter ies contain su lfuric ac id and
lead and must always be disposed of prop ­
erly i n compliance w ith all environmental
regu lations . D ispos ing of vehicle batteries
improper ly is very dangerous to t he envi­
ronmen t.

280 Emergency situations
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 ope rations.
Starting by pushing or
towing
Q;) Note
Vehicles w ith an automatic transmission
cannot be started by pus hing o r tow ing.
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 jumpe r cables to start the en­
g ine .
Jumper cables
Use only jumper cables of sufficiently large
cross section to carry the starter current safe­
ly. Refer to the manufacturer's specif ications.
Use only jumper cables with
insulated termi­
na l clamps which are distinctly marked:
plus(+) cable in most cases colored red
minu s(-) cable
in most cases colored black .
A WARNING
Batteries contain electricity, acid, and gas.
Any of these can cause very serious or fatal
inju ry. Follow the instructions below for
safe handling of your veh icle's battery.
- Always shield you r eyes and avoid lean­
ing over the battery whenever possible.
- A discharged battery can freeze at tem­
peratures just be low 32 °F (0 °C). Before connecting a
jumper cable, you must
thaw the frozen battery complete ly, 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 vo ltage 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 d ifferent voltage
or substantially different "Ah" rating
may cause an exp losion and personal in­
jury.
- Never charge a frozen batte ry. 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 batter ies of different voltage or
substantially different capacity (Ah) rat­
ing may cause an exp losion 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 a ll
WARNINGS
¢page 217.
(D Note
-App lying a higher voltage booster bat­
tery will cause expensive damage to sen­
sitive electronic components, such as
contro l units, relays, radio, etc .
- Th ere must be no electrical contact be­
tween the vehicles as otherwise current cou ld already start to f low as soon as the
positive(+) terminals are connected. .,.
