2012 AUDI A3 stop start

used today are underinflated just by looking
at them.
Therefore, be sure to check tire pressures at l eas t once a mon th and always before going
on a long trip. Make sure to take the number
of people and the amount of luggage into ac­
count when adjusting tire pressure for a trip -
even one that you would not consider to be
"long." See ¢
page 220, Tires and vehicle
load limits
for more important information .
A lways use an accurate tire pressure gauge
when check ing and adjusting inflation pres­
sures . Check all of the tires and be sure not to
forget the spare t ire . If the pressure in any tire
is too high when the tire is "cold," let air out
of the tire slowly with the edge of the t ire
gauge and keep checking the pressure until
you reach the p ress ure th at is cor rect for the
l oad (passengers and luggage) and kind of
driving you plan to do .
I f the p ressu re in any tire is too low , note the
d ifference between the pressure in the cold
tire and the pressure you need and add the air
that you need to reach the correct pressure for
the vehicle load (passengers and luggage) for
the tires on your vehicle as listed on the on
your veh icle and in this manual and the kind
of dr iving you p lan to do.
Never e xceed the m aximum inflation pre s­
su re li sted on th e tir e side wall for any rea ­
son.
Remember that the vehicle manufacturer, not
the tire manufacturer, determines the co rrect
tire p ressure for the tires on your vehicle .
It is important to check the tire pressure when
the tires are cold .
- Read the requ ired ti re p ressu re from the tire
pressure label. On USA veh icles, the t ire
pressure label is located on driver's side 8-
pillar . On Canada vehicles, the tire pressure
label is located either on the driver's side 8-
pillar or inside the fuel fi ller flap.
- Turn the valve stem cap counter-clockwise
to remove it from the tire valve.
- Place the air pressure ga uge on the valve.
Tire s an d wheel s 219
- The tire pressures should only be checked
and adj usted when the tires are co ld . The
slightly raised pressures of warm tires must
not be reduced.
- Adjust the tire pressure to the load you are
carrying.
- Reinstall the valve stem cap on the va lve.
When should I check the tir e pressu re?
T he co rrect tire pressu re is especially impor ­
tant a t high speeds. The pressure should
therefore be checked at least once a month
and always before starting a jo urney . Do not
forget to check the tire pressure for the spare
whee l
¢page 234.
When should I adjust the tire pres sur es?
Adjus t the t ire press ure to the load you a re
carrying . After changing a whee l
or rep lacing
whee ls you have to adjust the tire pressu res
on all whee ls. In addition, yo u m ust then initi­
ali ze the new t ire pressures in the tire pres­
sure monitoring system*¢

A WARNING
...---
Incorrect tire pressures and/or underinfla-
tion can lead sudden tire fa ilure, loss of
control, collision, serio us personal injury
or even death.
- When the warning symbol
ti] appears in
the instrument cluster, stop and inspect
the t ires.
- Inco rrect tire pressure and/or underinfla­
tion can cause increased tire wea r and
can affect the hand ling of the vehicle and
s topping abi lity.
- I nco rrect tire pressures and/or unde rin­
flation can a lso lead to sudden t ire fail­
ure, including a blowou t and sudden de­
flation, ca using loss of vehicle contro l.
- The driver is responsib le for the correc t
tire pressures for all tires on the veh icle.
The applicable pressure values are locat­
ed on a sticker on the dr iver's side 8-pil­
lar or on the ins ide of the fuel filler flap. •

maneuvers. Stop as soon as possible and
check the tires and their pressures. In­
flate the tire pressure to the proper pres­
sure as indicated on the vehicle's tire
pressure label ¢
page 216. Driving on a
significantly under-inf lated tire causes
the tire to overheat and can lead to tire
failure. Under-inflation also is likely to
impair the vehicle's handling and stop­
ping ability.
- T he driver is responsible for maintain ing
the correct tire pressures. You must
check the tire pressures regularly.
- Under certain cond itions (such as a spor­
ty driving style, winter conditions or un­
paved roads), the pressure monitor indi­
cator may be delayed.
- Ask your authorized Audi dealer if run­
flat tires may be used on your vehicle .
Your vehicle registration becomes invalid
if you use these tires when not permit­
ted. Damage to your veh icle or acc idents
could also result .
(D Tips
- The tire pressure monitoring system
stops working when there is an ESP/ABS malfunction .
- Using snow chains may result in a system
malfunction.
- Tires with the identification "AO" or "RO"
have been specially matched with your
Audi. We recommend using only these
tires because they meet the highest
standards regarding safety and driving
characteristics when used correctly. Your
a uthorized Audi dea ler will g ladly pro­
v ide you w ith more information.

2. Otherwise apply the hand brake and shift
into idle gear if your vehicle has manua l
transmission, and put the selector lever
into P position if your vehicle has auto­
matic transmission.
3 . For both vehicles switch off all consumers
and the ig nition .
Connectin g/disco nn ecting th e jumper
cable
4 . Connect one end of the red jumper cable
to the positive term inal
(D ¢ fig . 193 of
the discharged battery @ ¢0
in General
information of starting assistance on
page 249 .
5. Connect the other end of the red jumper
cab le to the positive termina l@ of the
booster battery @.
6 . Connect one end of the black jumper ca­
b le, preferably at the ground point. Other­
wise, connect it to the negative terminal
@ of the booster battery @.
7 . Connect the other end of the black jumper
cab le to the
ground po int (bolt head )©
in your v ehi cle @ .
8. Route the jumper cables so that they can­
not catch in any rotating parts in the en­
gine compartment.
Starting the engine
9 . Start the engine of the vehicle provid ing
assistance and allow it to run at idle .
10. Now start the eng ine o f the vehicle w ith
the discharged battery, wa it for two to
three minutes unti l the engine "runs"
smoothly .
11. If the engine does not start: Stop trying
after
10 seconds and then try again after
about
30 seconds.
12 . In the veh icle that has received start as­
sistance, turn on the heater blower and
the rea r window heat ing to eliminate any
voltage peaks when disconnecting. Driv­
ing lights must be swi tched off!
13. Disconnect the cable whi le the engine is
running exact ly in
reverse order to that
described in¢
page 250, Connecting/dis­
connecting the jumper cable.
When do ing so, make sure that the cable cannot con­
tact rotating engine parts.
14. Turn the heater b lower and the rear w in-
dow heating off again .
The battery is vented to the outside to prevent gases from entering the vehicle interior .
Make sure that the jumper clamps are we ll
connected with thei r
metal ports in full con­
tact
with the battery terminals .
A WARNING
To avoid serious personal injury and dam­
age to the vehicle, heed all warnings and
instructions of the jumper cable manufac­
turer. If in doubt, call for road service.
- Jumper cables must be long enough so
that the veh icles do not touch.
- When connecting jumper cables, make sure that they cannot get caught in any
mov ing parts in the engine compart­
ment.
- Before you check anything in the engine
compartment, always read and heed all
WARNINGS ¢page 187, Engine com­
partment.
{CT) Note
Improperly connected jumper cab les can
damage or destroy the generator .
- Do not use the battery negative terminal
for jump start ing or a malfunct ion could
occur in the vehicle electrical system.
- Always connect POSITIVE(+) to POSI-
TIVE(+), and NEGATIVE(-) to NEGATIVE
( - ) term inal.
- Check that all screw p lugs on the battery
cells are screwed in firm ly . If not, tighten
plugs prior to connecting clamp on nega­
tive batte ry term inal.
- Please note that the procedure for con­
necting a jumper cable as described
above applies specifically to t he case of
your vehicle being jump st arted. When
yo u are g iving a jump sta rt to another ve­
hicle, do
not connect the minus( -) cable
to the minus (-) terminal on the dis­
charged battery@¢fig.193 . Instead,
