fuel pressure AUDI A3 2012 Owner´s Manual

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*¢
page 230.
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. •
•

220 Tire s and wheel s
-Only when all tires on the vehicle are fi l­
led to the correct pressure, the tire pres­
sure monitoring system* can work correctly .
- The use of incorrect tire pressure values
can lead to accidents or other damage.
Therefore it is essential that the driver observe the specified tire pressure va lues
for the tires and the co rrect p ressu res fo r
the f unct ion of the tire pressure mo nitor­
ing system*.
- Always inflate t ires to the recommended
and co rrec t tire pressu re before d rivi ng
off.
- Driv ing with under inflated ti res bend
more, lett ing them get too ho t res ulting
in tread separation, sudden t ire fail ure
and loss of control.
- E xcess ive speed and/overloading can
cause heat bui ld -up, sudden t ire fail ure
and loss of control.
- If the tire press ure is too low or too high,
the tires wi ll wear prematu rely and the
vehicle will not hand le we ll.
- If the t ire is no t flat and you do not have
to change a wheel immediate ly, drive at
reduced speed to the nearest service sta­
t ion to check the tire pressure and add
air as required.
Driving without va lve stem caps can cause
damage to the tire va lves. To prevent this,
always make sure that facto ry installed
valve stem caps on all wheels are secure ly
mounted on the valve.
@) For the sake of the environment
Underinf lated tires will a lso increase t he
fue l consumption .
Tires and vehicle load limits
There are limits to the amount of load or
weight that any veh icle and any t ire ca n car ry .
A veh icle that is overloaded w ill not ha ndle
well a nd is more difficult to s top. Over load ing
c a n no t on ly lead to loss of veh icle con tro l, but can also damage important parts of the
vehicle and ca n lead to sudden tire fai lure, in ­
clud ing a b lowout and sudden deflation that
can cause the vehicle to crash.
Your safety an d that of your passengers also
depends on making sure that load limits are
not exceeded . Vehicle load includes everybody
and everything in and on the veh icle. These
load lim its are technically referred to as the
vehicle's
Gro ss Vehicle Weight Rating
("GVWR").
The "GVWR" includes the weight of the basic
vehicle, a ll factory installed accessories, a full
tank of fuel, o il, coolant and other fluids plus
maximum load. The max imum load incl udes
the number of passengers that the vehicle is
i ntended to car ry ("seat ing capac ity ") with an
a ss u med we igh t of 150 lbs (68 kg) for e ach
passenge r at a designated seating posi tion
and the total weight of any luggage in the ve ­
hicle . If you tow a trai ler, the weight of the
trai ler hitch and the tongue weight of the
loaded tra iler must be included as part of the
vehicle load.
T he
G ros s Axle Weight Rating ("GAWR") is
the maximum load that can be applied at each of the vehicle's two axles.
The Gross Vehicle Weight Rating and the Gross Ax le Weight Rating are listed on the
safety comp liance sticker label located e ither
on the dr iver's s ide B-pillar or on t he ins ide of
the fuel filler flap . Your Audi has 5 sea ting po­
s itions, 2 in the front and 3 in the rear for to ­
tal seating capacity of 5 . Each seat ing pos ition
has a safety belt
q page 113, Safety belts.
The fac t that there is a n upper limit to your
vehicle's G ross Vehicle Weight Rating means
that the total weight of whatever is bei ng car­
ried in the vehicle ( in cl ud ing the weight of a
t ra ile r hi tc h and the tongue we igh t of the
loaded trail er) is lim ite d. T he more p assen­
gers in the vehicle or passengers who are
heavier than the standard weights assumed
mean that less weight can be carried as lug-
gage.

or ridges on the road, part icu larly if the tire is
u nderinflated.
I n o rder to m inim ize the o ccurrence of impact
damage to the t ires of your vehicle, we recom­
mend that you observe the following precau ­
tions:
- Always maintain recommended infla tion
pressures. Check your t ire pressure every
2,000 miles (3,000
km) and add air if neces ­
sary .
- Drive carefu lly on roads with potholes, deep
gullies or ridges. The impact from driving
t h rough or over such obstacles can damage
your tires. Impact with a curb may also cause damage to your tires.
- After any impact, immediately inspect your
tires or have them inspected by the nearest
authorized Aud i dealer. Replace a damaged
t ire as soon as possible .
- Inspect your t ires every 2,000 miles (3,000
km) for damage and wear . Damage is not al­
ways easy to see . Damage can lead to loss of
air and underinflation, wh ich could eventu­
ally cause t ire failure . If you be lieve that a
t ire may have been damaged, replace the
t ir e as soon as possible.
- T hese tires may wea r mo re quick ly than oth­
ers.
- Please a lso remember that, wh ile these t ires
deliver respons ive handling, they may ride
l ess comfortably and make mo re no ise than
other choices.
Reduced performance in winter /co ld
sea son condit ion s
All ti res a re des igned for certa in pu rposes.
The low aspect ratio, ultra high performance
tires originally installed on your vehicle are in­
tended for max imum dry and wet road per­
formance and handling. They are not suitable
for cold, snowy or icy weather condit ions. If
you dr ive under those circumstances, you
should equip your vehicle with all -season or
winter tires, which offer better traction under
those cond it ions. We suggest you use the rec­
ommended snow or all-season tires specified
fo r your vehi cle, or their eq uivalent. Refer to
q page 22 7 for more detailed infor­
mation regarding winter tires.
Tire pressure monitoring system
ill General notes
Applies to veh icles: w ith tire pressure monitoring system
Each tire, incl uding the spare ( if provided),
sho uld be checked monthly when co ld and in­
flated to the inflation pressure recommended by the veh icle manufacturer on the veh icle
placard or tire inflation pressure label. (If your
vehicle has tires of a different size than the s ize indicated on the vehicle placard or tire in­
flat ion p ressure labe l, you should dete rmine
the p roper t ire infla tion p ress ure fo r those
t i res.)
As an added safety feature, your ve hicle has
been equipped with a tire pressure mon itoring
system ( TPMS) tha t illum ina tes a low ti re
pressure tel ltale when one or more of your
tires is significant ly under-inflated . Acco rding­
l y, when the low tire pressure te lltale i llumi­
nates, you should stop and check your tires as
soon as possib le, and inflate them to the
proper pressure. Driving on a sign ificantly un­
der- inflated t ire causes the tire to overheat
and can lead to tire fa ilure . Under-inflation al ­
so reduces fuel effic iency and tire tread life,
and may affect the vehicle 's handling and
stopp ing ability.
Please note that the TPMS is not a substitute
for proper tire ma intenance, and it is the driv­
er's respons ibility to maintain co rrect tire
pressure, even if under-inflation has not
reached the leve l to tr igger illum inat ion of the
T PMS low tire pressu re tellta le .
You r vehicle has also been equipped with a
T PMS ma lf un ction indicator to ind icate when
the sys tem is not operating properly. The
T PMS ma lf u nction indicator is combined w ith
t h e low tire pressure te lltale. When the sys­
tem detects a malfunction, the telltale will
flash for approximately one min ute and then ..,_
