2015 AUDI S3 warning

230 Checking and Filling
-Do not expose the battery to an open
flame, electric sparks or an open light.
- Do not smoke.
- Do not interchange the positive and neg-
ative cables.
- When working on the battery, be sure
not to short-circuit the terminals with
tools or other metal objects. This would
cause the battery to heat up very quickly,
which could lead to damage or explosion
and personal injury.
- When a battery is charged, it produces
hydrogen gas which is explosive and
could cause personal injury.
- Always keep the battery well out of the
reach of children.
- Before work is done on the electrical sys­
tem, disconnect the negative ground ca­ ble.
- Before performing any work on the elec­
trical system, switch off the engine and ignition as well as any electrical equip ­
ment . The negative cable on the battery
must be disconnected . If you are just go­
ing to replace a light bulb, then it is
enough to switch off the lights.
- Before disconnecting the battery, switch
off the anti-theft alarm system! Other­
wise you will set off the alarm.
- When disconnecting the battery, first
disconnect the negative cable and then
the positive cable .
- Before reconnecting the battery, make
sure all electrical consumers are switch­
ed off. Reconnect the positive cable first
and then the negative cable. Never inter­
change the cables -this could start a fire!
- Never charge a frozen or a thawed-out
battery. It could explode! If a battery has
frozen, then it must be replaced. A dead battery can free ze over at 32°F (O°C).
- Make sure the vent hose is always attach­
ed to the opening on the side of the bat­
tery.
- Never use batteries which are damaged.
There is the danger of an explosion! Al­
ways replace a damaged battery . A WARNING
-California Proposition 65 Warning:
- Battery posts, terminals and related ac­
cessories contain lead and lead com­
pounds, chemicals known to the State of
California to cause cancer and reproduc­
tive problems . Wash hands after han­
dling.
(D Note
- Do not disconnect the vehicle battery
when the ignition is on or when the en ­
gine is running, otherwise, you will dam­
age electronic components in the electri­
cal system.
- If your vehicle is going to stand for a
long period of time without being driven,
protect the battery from "freezing", oth­
erwise it will be damaged and will then
have to be replaced.
Battery charging
Starting the engine requires a well charged
battery.

14.8 Volts )
For technica l reasons do not use a battery
charger that uses voltage g reate r than
14.8 Volts to charge your veh icle's battery.
WARNING
Charging a battery can be dangerous.
- Always fo llow the oper ating instructions
provided by the battery charge r manu­
fact urer when charging your battery.
Checking and Fillin g 231
-Never charge a frozen battery. It may ex­
plode because of gas trapped in the ice .
Allow a frozen battery to thaw out first.
- Do not reuse batteries wh ich were fro­
zen. The battery housing may have
cracked and weakened when the battery
froze.
- Charge the battery in a well ventilated
area. Keep away from open flame or elec­
trical spark. Do not smoke. Hydrogen gas
generated by the battery is explos ive.
- To reduce the danger of explosion, never connect or d isconnect charger cab les
while the charger is ope rat ing.
- Fast charging a batte ry is dangerous and
should only be attempted by a compe­
tent techn ic ian with the prope r equip­
ment.
- Battery acid that may spi ll dur ing cha rg­
ing should be washed off wi th a solut io n
of wa rm w ater and baking soda to neu­
trali ze the ac id.

Neve r use a fast cha rger as a boost er to
star t the engine. This w ill ser iously dam­
age sens it ive e lectronic componen ts, su ch
as cont ro l units, re lays, 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.
Inte lligent energy management in your vehi­
cl e is responsible for dist ributing the elect ri­
ca l energy throughout yo ur vehicle
<=> page 194 . The intelligent energy manage­
ment system will keep the engine battery
charged better than vehicles without this sys­
tem . To make sure the additional electrical en­
ergy is ava ilab le once again after you have
changed the batte ry, we recommend that you
insta ll batteries of the same type and manu-
factu re on ly (the same as those installed at

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

pattern.
Hidden damage
Damage to tires and rims is of­
ten not readily visible. If you
notice unusual vibration or the
vehicle pulls to one side, this may indicate that one of the
tires has been damaged . The
tires must be checked immedi­
ately by an authorized Audi
dealer or qualified workshop.
Unidirectional tires
A unidirectional tire can be identified by arrows on the
sidewall, that point in the direc­
tion the tire is designed to ro­
tate. You must follow the speci­
fied direction of rotation. This is
necessary so that these tires
can develop their optimum
characteristics regarding grip,
road noise, wear and hydro­
planing resistance. For more in­
formation
¢page 274.
&_ WARNING
New tires or tires that are
old, worn or damaged cannot provide maximum control
and braking ability. -New
tires tend to be slip­
pery and must also be bro­
ken-in. To reduce the risk of
losing control, a collision
and serious personal inju­
ries, drive with special care
for the first 350 miles (560 km).
-Driving with worn or dam­ aged tires can lead to loss of
control, sudden tire failure,
including a blowout and
sudden deflation, crashes
and serious personal inju­ries. Have worn or damaged
tires replaced immediately.
-Tires age even if they are
not being used and can fail
suddenly, especially at high
speeds. Tires that are more
than 6 years old can only be
used in an emergency and
then with special care and at low speed.
-Never mount used tires on your vehicle if you are not sure of their "previous histo­
ry." Old used tires may have
been damaged even though
the damage cannot be seen
that can lead to sudden tire
failure and loss of vehicle
control.

244 Tires and wheels
The correct tire pressure for the
spare wheel is located on a la­
bel on the driver's side 8-pillar .
Because technical changes may
be made to vehicle equipment
during the model year, always
compare the tire size designa­
tion on the tire pressure label
on your vehicle with the tires on
your vehicle. Make sure that the
tire size information on the ve­
hicle label is the same as the
size of the tires on the vehicle.
This is especially important if
the vehicle belongs to someone else or you bought the vehicle
with different rims/tires or you bought the vehicle as a previ­
ously owned vehicle.
Remember, your safety and
that of your passengers also de­
pends on making sure that load
limits are not exceeded. Vehicle
load includes everybody and ev­
erything in and on the vehicle.
These load limits are technical­
ly referred to as the vehicle's
Gross Vehicle Weight Rating
("GVWR"). The Gross Axle
Weight Rating ("GAWR") is the maximum load that can be ap­
plied at each of the vehicle's
two axles. The Gross Vehicle Weight Rating and the Gross
Axle Weight Rating are listed
on the safety compliance stick­
er label located on the driver's
side 8-pillar.
The tire pressure
label on your Audi lists the
maximum combined weight of
all of the occupants and lug­ gage or other cargo that the ve­
hicle can carry. For the location
of the tire pressure label
~fig. 168.
A WARNING -
Overloading a vehicle can
cause loss of vehicle control,
a crash or other accident, se­
rious personal injury, and
even death.
-Carrying more weight than your vehicle was designed to carry will prevent the ve­
hicle from handling properly
and increase the risk of a
loss of vehicle control.
-The brakes on a vehicle that has been overloaded may not be able to stop the vehi­
cle within a safe distance.
-Tires on a vehicle that has been overloaded can fail
suddenly causing loss of
control and a crash.

_& WARNING
- Incorrect tire pressures
and/or underinflation can
lead to a serious or fatal ac­
cident.
- Incorrect tire pressures
and/or underinflation cause
increased tire wear and can
affect the handling of the
vehicle.
-Incorrect tire pressures and/or underinflation can
also lead to sudden tire fail­ure, including a blowout
and sudden deflation, caus­ ing loss of vehicle control.
Tires and wheels 245
Checking tire pressure
The correct tire pressure for the
tires originally installed on
your vehicle is listed on the tire pressure label located on driv­ er's side 8-pillar.
The recommended tire pres­
sures are on the tire pressure label and in the table
¢ page 240~ Cold tire inflation
pressure.
This means that the
pressure must be checked and
adjusted when the tire has not
been driven for more than a
couple of miles (kilometers) at
low speeds during the previous
three hours. Air in the tires ex­ pands when the tire heats up as
a result of internal friction as it
flexes in use. The tire pressure is higher when the tire has
warmed up than when it is "cold ."
It is the inflation pressure in a
"cold" tire that counts. There­
fore, you should never let air
out of a warm tire to match
"Cold tire inflation pressure" recommendations ¢
page 240.
The tires would then be under­
inflated and could fail sudden­
ly .
