@ Tips
With the front seats, the height adjust­
men t of the seat can also be used to adjus t
the posit ion of the safety be lts.
Improperly worn safety belts
Incorrectly positioned safety belts can cause
severe injuries .
Wearing safety belts improperly can cause se­
rious injury or death. Safety belts can o nly
work when they are correctly positioned on
the body . Improper seat ing pos itions reduce
the effectiveness of safety belts and will even
i ncrease t he risk of inju ry and death by mov­
ing the safety be lt to crit ica l areas o f the
body. Improper seating positions also in­
crease the risk of serious injury and death
when an airbag deploys and strikes an occu­
pant who is not in the correct seating posi­
tion. A driver is respons ible for the safety of
all veh icle occupants and especially for chil­
dren . Therefore:
"" Never permit anyone to assume an incorrect
sitting position in the vehicle while traveling
QA .
A WARNING
Improperly worn safety belts increase the
r isk of ser ious persona l injury and death
whenever a vehicle is being used.
- Always ma ke sure that all vehicle occ u­
pants are co rrectly restra ined and stay in
a correc t seating position whe never the
veh icle is being used .

is scrapped, all applicable safety pre­
cautions must be followed.
@ For the sake of the environment
Undeployed a irbag modu les and preten­
sioners might be classified as Perchlorate Material - special handling may apply, see
www.dtsc.ca.gov/haza rdo uswaste/per­
chlorate. When the vehicle or parts of the

Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced A irbag Sys­
tem pe rforms in a crash. For example, us ing
tire-r im combina tions not app roved by Aud i,
lowe ring the vehicle, ch anging the stiffness o f
the suspension, incl uding the springs, s uspen ­
sion struts, shock absorbers etc. can change
the forces that are measured by the a irbag
sensors and sent to the electronic control
un it. Some suspension changes can, for exam­
p le, increase the force levels measured by the
sensors a nd make the airbag system deploy in
crashes in w hich it would not dep loy if the
changes had not been made . Other kinds of
ch an ges may reduce the force levels meas ­
u re d by the sensors and prevent the airbag
from deploying when it sho uld .
The senso rs in the safety belt buckle fo r th e
d river a nd front p asse nger sea t tell the elec ­
tronic control module if the safety belt is
l atched or not .
If the safety belt is being used,
the front airbag will dep loy at a slightly high­
er rate of vehicle deceleration than if the safe­
ty belt is not being used. Therefore, in a par- t
icu lar collisio n, it is possible that an airbag
will not dep loy at a seat ing position where the
safety belt is be ing used b ut w ill inflate at the
pos ition where the safety belt is not be ing
used. It is important that nothing interfere
with t he safety be lt buckles so that the sen ­
sors can send the correct info rmation about
safety belt use to the electronic control un it .
_&. WARNING
Changi ng the vehicle's suspension includ ­
i ng use of unapp roved tire-rim combin a­
tions can change Advanced Airbag per­
formance an d increase the risk of serious
pe rsonal injury in a crash .
- Never install s uspension components
that do not have the same pe rformance
characteristics as the components o rigi­
na lly installed on your vehicle.
- Never use tire-rim combinations that
have not been approved by Audi.
Knee airbags
Description of knee airbags
App lies to vehicles : wi th knee airbags
The knee airbag system can provide supple­
mental protection to properly restrained
front seat occupants .
Fig. 1 64 Driver 's knee a irbag
T he dr iver knee airbag is in the ins trument
pane l underneath the steering wheel
~ fig. 164, the airbag for the passenger is at
about the same height in the instrument pan-
el underneat h the glove compartment. .,.

184 Child Safety
-Always move the front passenger seat in­
to the rearmost position of the passen­
ger seat's fore and aft adjustment range,
and as far away from the airbag as possi­
ble before installing the child restraint .
- Always make sure that nothing prevents
the front passenger's seat from being
moved to the rearmost position in its
fore and aft adjustment range.
- Always make sure the backrest is in an
upright position .
- Never place or use any electrical device
(such as a laptop, CD player, electronic
games device or power inverter) on the
front passenger seat if the device is con­
nected to the 12-volt socket or the ciga­
rette lighter socket.
- If a seat heater has been retrofitted or
otherwise added to the front passenger
seat, never install any child restraint sys­
tem on this seat.
- Make sure that there are no wet objects
(such as a wet towel) and no water or
other liquids on the front passenger seat
cushion.
- Never place objects on the seat (such as
a laptop, CD player, electronic games de­
vice or power inverter). These may influ­
ence the electrical capacitance measured by the capacitive passenger detection
system and can also fly around in an acci­ dent and cause serious personal injury.
- Make sure that the
PASSENGER AIR BAG
OFF
light comes on and stays on all the
time whenever the ignition is switched
on.
- If the
PASSENGER AIR BAG OFF light
does not come on and stay on, immedi­
ately install the forward-facing child seat
at a seating position on the rear seat and
have the airbag system inspected by your
authorized Audi dealer.
- Take the child restraint off the front pas­
senger seat and install it properly at one
of the rear seat positions if the
PASSEN­
GER AIR BAG OFF
light does not stay on
whenever the ignition is switched on.
Booster seats and safety belts
Properly used booster seats can help protect
children weighing between about 40 lbs . and
80 lbs . (18 kg and 36 kg) who are less than 4
ft. 9 in. (57 inches/1.45 meters) tall.
Fig. 174 Rea r seat : child p rop erly res trained in a boos­
te r se at
The vehicle's safety belts alone will not fit
most children until they are at least 4 ft . 9 in .
(57 inches/1.45 meters) tall and weigh about
80 lbs.
(36 kg). Booster seats raise these chil­
dren up so that the safety belt will pass prop­
erly over the stronger parts of their bodies
and the safety belt can help protect them in a
crash.
"" Do not use the convertible locking retractor
when using the vehicle's safety belt to re­
strain a child on a booster seat.
"" The shoulder belt must lie as close to th e
center of the child's collar bone as possible
and mu st lie flat and snug on the upper
body.
It must never lie across the throat or
neck . The lap belt must lie across the pelvis
and never across the stomach or abdomen .
Make sure the belt lies flat and snug . Pull on
the belt to tighten if necessary .
"" If you must transport an older child in a
booster seat on the front passenger seat,
you can use the safety belt height adjust­
ment to help adjust the shoulder portion
properly .
"" Secure unused safety belts on the rear seat

Children up to at least 8 years old (ove r 40 lbs
or 18 kg) are best protected in child safety
seats designed for their age and weight . Ex-

-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 .

A WARNING
Sudden tire failure can lead to loss of con­
trol, a crash and serious persona l injury!
- Never drive a veh icle when the tread on
any tire is worn down to the wear indica­
tors.
- Worn tires are a safety hazard, they do not grip well on wet roads and increase
your risk of"hydrop lan ing" and loss of
co ntrol.
- Always keep chemicals that can cause
tire damage, such as grease, oil , gasoline
and brake fluid away from t ires.
- Tires age eve n if they are not be ing used
and can fail suddenly, especially at high
speeds. T ires that are more than 6 years
o ld can only be used in an emergency
and then with spe cial care a nd at lower
s peeds.

258 Tires and wheels
contribution to good road ho lding and safe
handling when in good condition and properly
inflated
¢ ,& .
We recommend that all work on tires and
wheels be performed by an authorized Audi
dealer. They are familiar with recommended
procedures and have the necessary spec ial
too ls and spare parts as well as the proper fa­
cilities for disposing of the old tires.
Authorized Audi dealers have the necessary information about technical requ irements for
installing or changing tires and rims.
Replacing tires and wheels
Tires should be rep laced at least in pairs and
not individually (for example both front tires
or both rear tires together).
Be sure to read and heed the information to
the tire pressure monitoring system*
¢pa ge 264.
Always buy rep lacement radial tires that have
the same specifications as the tires approved
for your vehicle by Audi. Replacement t ires
must always have the same load rating speci­
fication as the original equipment or approved
optional tires listed in the table
c:> page 250.
Aud i-approved specification ti res are specially
matched to your vehicle and its load limits,
and can contribute to the important road hold­
ing, driving characteristics, and safety of the
vehicle. The table
(c:>page 250) lists specifica­
tions of the tires approved for the Audi mod­
els covered by your Owner's Literature .
The tire pressure label located on driver's side
B-pillar
(c:> fig. 197) lists the specifications of
the orig inal equipment tires installed on your
vehicle at the time it was manufactured.
Federal law requires tire manufacturers to
place standardized information on the s ide­
wall of all tires
c:> fig. 200. This information
identifies and describes the fundamental
characterist ics, the quality grade of the tire
and also provides a tire ident ificat ion number
fo r safety standard certificat ion and in case of
a recall.
Tire specifications
Knowledge of tire specifications makes it eas­
ier to choose the correct tires. Radial ti res
have the tire specifications marked on the
sidewa ll, for examp le:
255/40 R 19 100 H XL
This conta ins the following information:
P Indicates the tire is for passenger cars
(where app licable)
255 Nominal tire width in mm of the tire
from sidewall edge to sidewall edge. In general, the larger the number, the wider
the tire
40 Height/w idth ratio in percent (aspect ra-
t io)
R Tire construct ion: Radial
19 Rim diameter code (in inches)
100 Load rating code
H Speed rating letter code
XL (or "xl", "E XTRA LOAD" or "RF") Indica tes
that the tir e is a "Reinforced" or an "Ext ra
Load" t ire
M+S (or "M/5") Indicates that the tire has
some mud and snow capability
The tires could also have the information of
direction of rotat io n
¢ page 246.
Tire manufacturing date
The manufacturing date is also indicated on
the tire sidewall (possibly on ly on the
inner
side of the wheel):
"DOT ... 2212 ... " means, for example, the tire
was produced in the 22nd week of 2012.
Speed rating (letter code)
The speed rating letter code on the whee ls in ­
dicates the maximum permissible road speeds
c:> & in Winter tires on page 262.
p up to 93 mph (150 km/h)
Q up to 99 mph (158 km/h)
R up to 106 mph (170 km/h)
s up to 110 mph (180 km/h)
T up to 118 mph (190 km/h)
u up to 124 mph (200 km/h)
H up
to 130 mph (210 km/h)

@ Tips
Where snow chains are mandatory oncer­
tain roads, this normally also applies to
veh icles with all-wheel dr ive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque .
The design of whee l bolts is matched to the
factory insta lled rims . If different rims are fit­
ted, the correct wheel bolts with the right
length and correctly shaped bolt heads must
be used. This ensures that wheels are f itted
securely and that the brake system functions
correctly .
In certain circumstances, you may not use
wheel bolts from a different vehicle -even if it
is the same model
<=> page 291.
.&_ WARNING
Improperly tightened or maintained wheel
bolts can becom e loose caus ing loss of
cont ro l, a co llision and serious persona l in­
Jury .
- Always keep the wheel bolts and the
threads in the wheel hubs clea n so the
w heel bolts can t urn easily and be prop ­
erly t ightened .
- Never grease or oil the wheel bolts and
the threads in the wheel hubs. They can
become loose while d riving if greased or
oi led, even if tightened to the specif ied
torque.
- Only use whee l bolts that belong to the
rim being installed .
- Never use different whee ls bolts on your
vehicle.
- Always maintain the co rrect tighten ing
torq ue for the wheel bo lts to reduce the
risk of a wheel loss . If the tightening tor­
que of the wheel bolts is too low, they
can loosen and come out when the vehi­
cle is moving. If the tightening torque is
too high, the whee l bolts and threads
Tire s an d wheel s 263
can be damaged and the whee l can be­
come loose.
(D Note
The specified torque for the whee l bolts is
90 ft lb (120 Nm) with a tolerance of± 7,4
ft lb(± 10 Nm) . Torq ue whee l bolts diago­
nally. After changing a whee l, the torq ue
must be checked as soon as possible with a
torque wrench -preferably by an author­
i zed Audi dealer or qualified workshop.
Low aspect ratio tires
You r Aud i is facto ry-equ ipped w it h low aspect
ra tio tires. These tires have been tho ro ughly
tested and been se lec ted spe cifically for you r
model for their superb perfo rmance, road fee l
and handling under a variety of driving condi­
tions. Ask your authorized Audi dealer for
more details .
T he low aspect ratio of these t ires is ind icated
by a numera l of
55 or le ss in the tire's s ize
designation. The numera l represents the ratio
of the t ire's sidewa ll height in relation to its
tread width expressed in percentage. Conven­
tiona l tires have a he ight/w idth rat io of 60 or
more .
The performance of low-aspect -ra tio tire s is
particularly sens it iv e to improper inflation
pressure. It is therefore important that low
aspect ratio t ires are inflated to the specified
pre ssure and that the inflation pressur e is
regularly che cked and maintain ed. Tire pre s­
s ures should be checked at least on ce a
m onth and alwa ys before a long trip
¢ page 2 52, Checking tire pressure .
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damage d mo re
easily by impact w ith potholes, curbs, g ull ies
or ridges on t he road, partic ularly if the tire is
u nderinflated.
