2012 AUDI A3 fuel consumption

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.

228 Tires and wheels
The speed rating letter code( ¢ page 224) is
on the side wall of the tire
¢ page 223.
A WARNING
Winter tires have maximum speed limits
that may be lower than your vehicle's max­
imum speed . Always know the maximum
speed before driving off. Never drive faster
than the speed permitted for your specific
winter tires. This will cause damage to the
tires leading to an accident and serious
personal injury to you and your passen­
gers.
A WARNING I>=
Driving faster than the maximum speed
for which the winter tires on your vehicle
were designed can cause tire failure in­
cluding a blowout and sudden deflation,
loss of control, crashes and serious per­
sonal injuries. Have worn or damaged tires
replaced immediately.
- Winter tires have maximum speed rating
that may be lower than your vehicle's
maximum speed .
- Never drive faster than the speed for
which the winter or other tires installed on your vehicle are rated.
A WARNING
Always adjust your driving to the road and
traffic conditions. Never let the good ac­
celeration of the winter tires and all-wheel
drive tempt you into taking extra risks . Al­
ways remember :
- When braking , an all-wheel drive vehicle
handles in the same way as a front drive
vehicle.
- Drive carefully and reduce your speed on
icy and slippery roads, even winter tires
cannot help under black ice conditions.
@) For the sake of the environment
Use summer tires when weather condi­
tions permit. They are quieter, do not wear
as quickly and reduce fuel consumption.
Snow chains
Snow chains may be fitted only to the front
wheels, and only to certain tire sizes . Ask your
authorized Audi dealer on which tire sizes snow chains can be used.
If you are going to use snow chains, then you
must install them on the front wheels at
least.
The snow chains must have low-profile links
and must not be thicker than 0.53 inch
(13 .5 mm) , including the lock.
Remove wheel center covers and trim discs
before putting snow chains on your vehicle
¢ (!) . For safety reasons cover caps must then
be fitted over the wheel bolts. These are avail­
able from authorized Audi dealers.
A WARNING
=
Using the wrong snow chains for your vehi-
cle or installing them incorrectly can in­
crease the risk of loss of control leading to
serious personal injury.
- Snow chains are available in different
sizes . Always make sure to follow the in­
structions provided by the snow chain manufacturer.
- When driving with snow chains never
drive faster than the speed permitted for
your specific snow chains.
- Always observe local regulations.
(D Note
- Remove snow chains before driving on
roads not covered with snow to avoid
damaging tires and wearing the snow
chains down unnecessarily .
- Snow chains, which come into direct con­
tact with the wheel rim, can scratch or damage it. Therefore, make sure that the
snow chains are suitably covered. Check
the position of the snow chains after
driving a few yards and correct if neces­
sary. Follow the instructions from the
snow chain manufacturer when doing so. ..,.
