_& WARNING
Weak, damaged or improper straps used
to secure items to the roof rack can fail
during hard braking or in a collision and
cause serious personal injury .
- Make sure the roof rack is installed exact ­
ly as specified above
c::;, page 61 .
-Always use suitable mounting straps for
securing items to the roof rack to help
prevent items from shift ing or fly ing for­
ward.
- Items on the roof rack must always be
securely mounted .
- The use of a roof rack can negatively af­
fect the way a vehicle handles . Cargo
that is large, heavy, bulky, long o r flat
will have a greater negative inf luence on
the vehicle 's aerodynamics, center of
gravity and overall handling . Always
drive slowly, avoid sudden braking and
maneuvers when transporting cargo on
the roof of your vehicle.
- Never exceed the maximum permissible
load carrying capacity of the roof of your
vehicle, the perm issible axle weights and
the permiss ible total weight of your vehi­
cle
c::;, page 280, Weights .
@ For the sake of the environment
As a result of the increased wind resist­
ance created by a roof rack, your veh icle is
using fuel unnecessarily. So remove the
roof rack after using it.

- Loose objects in the passenger compart­
ment can fly forward during abr upt ma­
neuvers or accidents and injure occu­
pants .
- Always store objects in the luggage com­
partment and use suitable straps, partic­
ularly with heavy objects .
-
-When you transport heavy objects, al­
ways remember that a change in the cen ­
ter of gravity may result in a change in
the vehicle's handling characteristics.
- Follow all warnings
c::;, page 128, Driving
Safely .
(D Tips
The tire pressure must be ad justed to the
load -see the t ire pressure sticker located
on the dr iver's side B -pillar .

-Never mount used tires on yo ur vehicle if
yo u are not sure of their "previous histo­
ry." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss of vehicle control.
- If you notice unusual vibration or if the
vehicle pulls to one side when d riving, al­
ways stop as soon as it is safe to do so
and check the wheels and tires for dam­
age .

Glossary of tire and loading terminology
Accessory weight means the comb ined weight (in excess of
those sta ndard items which may be rep laced)
of au toma tic transmission, power steer ing ,
power brakes, power windows, power seats,
radio, and heater, to the extent that these
items are availab le as factory-installed equip­
ment (whether installed or not) .
Aspect ratio
means the rat io o f the height to the w idth of
the tire in percent . Numbers of 55 or lower in ­
dicate a low sidewall for improved steering re­
sponse and better overa ll handling on dry
pavement .
Bead
means the part of the t ire t hat is made o f
steel wires, wrapped or reinforced by ply cords
and that is shaped to fit the r im.
Bead separation
means a b reakdown of the bond between
components in the bead .
Cord means the strands forming the plies in the
tire.

typica l in those seasons . Aud i recommends
using winter tires during the winter
months . Low temperatures signif icant ly
dec rease the e lasticity of summer t ires,
which affects tract ion and brak ing ability.
If summer t ires are used i n very co ld tem ­
peratures, cracks ca n form o n the tread
bars , res ulting in perma nen t tire damage
that can cause loud driving noise and un­
bala nced ti re s. Audi i s not respon sible for
th is type of damage .
Cold tire inflation pressure
means the t ire p ress ure recommended by t he
vehicle manufacture r fo r a tire o f a des ignated
s ize t hat has not bee n driven for more than a
coup le o f miles (k ilometers) at low speeds in
the three hour period before the tire press ure
is m easured or adjusted.

248 Tire s and whee ls
- Only when all tires on the vehicle are fi l­
led to the correct pressure, the tire pres­
sure monitoring* system can work cor­ rectly.
- 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 values
for the tires and the correct pressures for
the funct ion of the tire pressure mon itor­
ing system*.
- Always inflate t ires to the recommended
and correct tire pressure before driving
off.
- Driv ing with under inflated ti res bend
more, letting them get too hot resu lting
in tread separation, sudden ti re fail ure
and loss of control.
- Excess ive speed and/overloading can
cause heat bui ld -up, sudden ti re fail ure
and loss of control.
- If the tire press ure is too low or too high,
the tires wi ll wear prematurely and the
vehicle will not hand le we ll.
- If the tire is not 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 factory installed
valve stem caps on all wheels are securely mounted on the valve.
@) For the sake of the environment
Underinf lated tires will a lso increase the
fuel 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 carry.
A veh icle that is overloaded w ill not handle
well and is more difficult to stop. Over load ing
can not on ly lead to loss of veh icle contro l, but can also damage important parts of the
vehicle and can lead to sudden tire fai lure, in­
clud ing a b lowout and sudden deflation that
can cause the vehicle to crash.
Your safety and 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
G ro ss Vehicl e We ight R ating
("GVWR").
The "GVWR" includes the weight of the basic
vehicle, all factory installed accessories, a full
tank of fuel, o il, coolant and other fluids plus
maximum load. The max imum load includes
the number of passengers that the vehicle is
intended to car ry ("seat ing capac ity") with an
ass umed we ight of 150 lbs (68 kg) for each
passenge r at a designated seating position
and the total weight of any luggage in the ve ­
hicle . If you tow a trai ler, the weight of the
trailer hitch and the tongue weight of the
loaded tra iler must be included as part of the
vehicle load.
The
G ro ss Axle We ight R ating ("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 Axle Weight Rating are listed on the
safety comp liance sticker label located on the
driver's side B-pillar . Your Audi has 5 seat ing
pos itions, 2 in the front and 3 in the rear for
total seating capacity of 5 . Each seating posi­
t ion has a safety belt
Q page 138, Safety
belts.
The fact that there is an upper limit to your
vehicle's Gross Vehicle Weight Rating means
that the total weight of whatever is being car­
ried in the vehicle ( includ ing the weight of a
t ra ile r hi tch and the tongue weigh t of the
loaded tra iler) is lim ited. The more passen­
gers in the vehicle or passengers who are
heavier than the standard weights assumed
mean that less weight can be carried as lug-
gage.

258 Tires and wheels
or ridges on the road, particularly if the tire is
underinflated.
I n o rder to minim ize the occurrence of impact
damage to the tires of your vehicle, we recom­
mend that you observe the following precau ­
tions:
- Always maintain recommended inflation
pressures. Check your tire 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
through 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 ir e as soon as possible .
- Inspect your tires 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 ir e may have been damaged, replace the
tire as soon as possible.
- T hese tires may wea r mo re quick ly than oth­
ers.
- Please a lso remember that, while these t ires
deliver respons ive handling, they may ride
less comfortably and make more no ise than
other choices.
Reduced performance in winter/cold
season conditions
All tires are designed for certain purposes.
The low aspect ratio, ultra high performance
tires originally installed on your vehicle are in­
tended for maximum dry and wet road per­
formance and handling. They are not suitable
for cold, snowy or icy weather condit ions. If
you drive 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
for your vehicle, or their equivalent. Refer
to
q page 255 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, including the spare ( if provided),
shou ld be checked monthly when co ld and in­
flated to the inflation pressure recommended
by the veh icle manufacturer on the vehicle
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
flation pressure label, you should determine
the proper tire inflation p ressu re 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) that illuminates a low tire
pressure telltale when one or more of your
tires is significant ly under-inflated. According­
l y, when the low tire pressure telltale i llumi­
nates, you should stop and check your tires as
soon as possible, 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 efficiency and tire tread life,
and may affect the vehicle 's handling and
stopping ability.
Please note that the TPMS is not a substitute
for proper tire ma intenance, and it is the driv­
er's responsibility to maintain correct tire
pressure, even if under-inflation has not
reached the level to trigger illuminat ion of the
TPMS low tire pressu re tellta le .
Your vehicle has also been equipped with a
TPM S malfunction indicator to ind icat e when
the system is not operating properly. The
T PMS ma lfunction indicator is combined with
the low tire pressure telltale. When the sys­
tem detects a malfunction, the telltale will
flash for approximately one minute and then ..,_
