What impairs driving safety?
Safe driving is directly related to the condition of the
vehicle, the driver as well as the driver's ability to concen­
trate on the road without being distracted.
The driver is responsible for the safety of the vehicle and all
of its occupants. If your ability to drive is impaired, safety
risks for everybody in the vehicle increase and you also
Controls and equip­
ment Safety first Vehicle operation
become a
hazard to everyone else on the road ~& .There ­
fore:
- Do not let yourself be distracted by passengers or by
using a cellular telephone.
- NEVER drive when your driving ability is impaired (by
medications, alcohol, drugs, etc.I.
- Observe all traffic laws, rules of the road and speed limits
and plain common sense.
- ALWAYS adjust your speed to road, traffic and weather
conditions.
- Take frequent breaks on long trips. Do not drive for more
than two hours at a stretch.
- Do NOT drive when you are tired, under pressure or when
you are stressed.
& WARNING
Impaired driving safety increases the risk of serious personal
injury and death whenever a vehicle is being used. •

-Safety belts ___ .:,__ _____________________________________ _
Automatic safety belt retractors
Every safety belt is equipped with an automatic belt retractor on the
shoulder bel t. This featu re locks the bel t when the belt is pulled out
fast, during hard braking and in an accident. The belt may also lock
when you drive up or down a steep hill or through a sharp curve. During normal driving the bel t lets you move freely.
Safety belt pretensioners
The safety belts are equipped with a belt pretension er that helps to
tighten the safety belt and remove slack when the pretensioner is
activated. The function of the pretensioner is monitored by a
warning light:::::, page
20, "Airbag system @;".
Switchable locking feature
Every safe ty belt except the one on the driver seat is equipped with
a switchable locking feature that must be used when the safety belt
is used to attach a child seat . Be sure to read the important informa­
tion about this feature:::::, page
200.
& WARNING
Improperly positioned safety belts can cause serious injury in an
accident :::::,
page 164, "Safety belt position" .
• Safety belts offer optimum protection only when the seat back
is upright and belts are properly positioned on the body.
• Never attach the safety belt to the buckle for another seat.
Attaching the belt to the wrong buckle will reduce safety belt
effectiveness and can cause serious personal injury.
• A passenger who is not properly restrained can be seriously
injured by the safety belt itself when it moves from the stronger
parts of the body into critical areas like the abdomen.
• Always lock the convertible locking retractor when you are
securing a child seat in the vehicle :::::,
page 202. •
Safety belt position
Correct belt position is the key to getting maximum
protection from safety belts.

straps of the front seat belts.
in. WARNING
Improperly positioned safety belts can cause serious personal
injury in an accident .
• The shoulder belt portion of the safety belt must be positioned
over the middle of the occupant's shoulder and never across the
neck or throat.
• The safety belt must lie flat and snug on the occupant's upper
body
:::::> fig. 168. Pull on the belt to tighten if necessary.
• The lap belt portion of the safety belt must be positioned as
low as possible across pelvis and never over the abdomen. Make
sure the belt lies flat and snug :::::, fig. 168. Pull on the belt to
tighten if necessary.
• A loose-fitting safety belt can cause serious injuries by shifting
its position on your body from the strong bones to more vulner-
able, soft tissue and cause serious injury. ..,.

Knee airbags
Description of knee airbags
The airbag system can pr ovide supplemental protection
t o properly restrained fron t se at occu pants.
Fi g. 175 Dr iver's
ai rba g
The airbag for the driver is located in the instrument panel under ­
neath the steering wheel=> fig. 175, the airbag for the passenger is
at about the same height in the instrument panel underneath the
g love compartment.
The knee airbag offers additional protection to the driver 's and
passenger's knees and upper and lower thigh areas as a supple­
ment to the safety be lts.
If the front airbags deploy, the knee airbags also deploy in frontal
coll isions above a certain severity=>
page 177, "More important
things to know about front airbags".
Besides their normal safety function, safety be lts work to help keep
the driver or front passenger in position in case of a frontal collision
so that the airbags can provide protection.
The airbag system is not a substitute for your safety belt. Rather, it is part of the overall occupant restraint system in your vehicle.
Always remember that the airbag system can only help to protect
you if you are wearing your safety belt and wearing it properly. This

In correct wheel alignment
Inc orrect wheel alignment can cause excessive tire wea r, impairing
the saf ety of the vehicle . If tires s how excessive wear , have the
whee l alig nment chec ked by an autho rized A udi deale r or q ualif ied
workshop .
All Wheel Drive
Vehicles with quattro ® must always have tires of the same si ze ,
cons tructi on and tread type . For details see => page 218 .
& WARNING
Sudden tire failure can lead to loss of control, a crash and serious
personal injury!
• Never drive a vehicle when the tread on any tire is worn down
to the wear indi cators .
• E specially in wet and slick driving situations , a preferably large
profile depth of the tires is necessary , and an approximately
similar profile depth of the front and rear axle tire s.
• The diminished driving safety , caused by too small of a tire
profile , is negatively perceivable especially in handling , in danger
of hydroplaning when driving through deep puddles and ponds ,
when driving around curve s, and in braking behavior.
• Worn t ires are a safety hazard , they do not grip well on wet
roads and increase your risk of "hydroplaning " and loss of control.
• Always keep chemicals that can cause tire damage , such a s
grease , oil , gasoline and brake flu id away from tires.
• Tires age even if they are not being used and can fail suddenly ,
espe cially at high speeds . Tires that are more than 6 years old can
only be used in an emergency and then with special care and at
lowe r speeds.
• Never mount used tire s on your vehicle if you are not sure of
their "previous history ." Old u sed tires may have been damaged
even though the damage cannot be seen that can lead to sudden
tire failure and los s of vehicle control. •

The tires and rims are essential parts of the vehicle's design. The
tires and rims approved by Audi are specially matched to the char­ acteristics of the vehicle and can make a major contribution to good
road holding and safe handl ing when in good condition and prop ­
erly inflated =>& .
We recommend that al l work on tires and wheels be performed by
an authorized Audi dealer . They are familiar with recommended
procedures and have the necessary special too ls and spare parts as
we ll as the proper facilities for disposing of the o ld tires .
Authorized Audi dealers have the necessary information about tech ­
n ical requirements for insta lling o r changing tires and rims .
Repl ac ing t ires and wheels
Tires should be replaced at least in pairs and not individually (for
example both front tires or both rear tires together).
On vehicles with tire pressure moni toring system*, be sure to read
and heed the information=>
page 287.
Always buy replace ment radia l tires tha t have the same specifica ­
tions as the tires approved for your vehicle by Audi . Replacement
tires must always have the same load rating specification as the
original equipment or approved optional tires listed in the table
=>
page 271.
A udi -appr oved specificat ion tires a re specially matched t o your
vehic le and its load limits, and can contribute to the important road- holding, driving characteristics, and safety of the vehicle

models covered by your Owner's Literature.
The tire pressure label located either on driver's side B -pi llar or
insi de the fuel filler flap(=>
page 271, fig. 208) lists the specifica ­
tions of the original equipment tires installed on your vehicle at the
time it was manufactured.
Federa l law requires tire manufacturers to place standardized infor ­
mation on the sidewa ll of all tires=>
page 279, fig. 211. This informa ­
tion identifies and descr ibes the fundamenta l characteristics, the
quality grade of the tire and a lso prov ides a tire identification

Wheel bolts
Wheel bolts must always be tightened to the correct
torque .
The design of wheel bo lts is matched to the factory installed rims . If
different rims are fitted, the correct wheel bolts with the right length
and correctly shaped bolt heads must be used. This ensures that
whee ls are fitted securely and that the brake system functions
correctly .
I n certain circumstances, you may not use wheel bolts from a
different vehicle -even if it is the same model~ page 318.
& WARNING
Improperl y tightened or maintained wheel bolt s can be come loose
c au sing lo ss of control , a co llis ion and seriou s personal injur y.
• Alwa ys keep the wheel bolt s and the th reads in the wheel hubs
c lean so the wheel bolt s can turn ea sily and be properl y tightened.
• Never gre ase or oil the wheel bolt s and the thre ad s i n the wheel
hub s. They can become lo ose while drivin g if gre ased or oiled ,
e ven if tig hten ed to th e specifi ed torque .
• Onl y use wheel bo lt s th at bel ong to the rim being in sta lled.
• Nev er use differ ent wheel s bolt s on your vehicle.
• Alway s m aintai n the corre ct t ightenin g to rq ue for the whee l
bo lt s to r edu ce the ri sk of a whe el los s. If the tighten ing torque of
t h e w heel bolt s is too l ow, they c an loose n a nd com e out when th e
v ehicl e is mov ing . If th e tighte ning torque is t oo high, the whe el
b ol ts an d threads can be dam ag ed and the whee l can become
loo se .
0 Note
The specified torque for the wheel bolts is 90 ft lb (120 Nm) with a
tolerance of ± 7,4 ft lb(± 10 Nm). Torque whee l bolts diagonally.
After changing a wheel, the torque must be checked as soon as possible with a torque wrench
-preferably by an authorized Audi
dea ler or qua lified workshop .•
Low aspect ratio tires
Your Audi is fac tory-equipped with low aspect ratio tires. These tires
have been thorough ly tested and been selected specifically for your
model for their superb performance, road feel and hand ling under
a variety of driving conditions . Ask your authorized Audi dealer for
more details.
The low aspect ratio of these t ires is ind icated by a numera l of 55 or
l e ss in the tire's size designation . The numera l represents the ratio
of the tire's sidewa ll height in relat ion to its tread w idth expressed
in percentage. Conventiona l tires have a height/width ratio of 60 or
more .
T he perform ance of lo w-as pect-rati o tire s is part ic ul arl y s ensit ive to
improp er infla tion pr essure. It i s there fore important that low
a s pect ra tio tir es are inflated to the sp ec ified pre ssure an d th at th e
i nfl ation pre ssure is regularl y checked and m aintained . T ir e pres ­
s ure s should b e checked a t lea st once a month and alw ays before a
long trip~ page 274, "Checking tire pressure".
What you can d o to avoid tire a nd rim dama ge
Low aspect ratio tires can be damaged more easi ly by impact with
potho les, curbs, gull ies or ridges on the road, particularly if the tire
is underinflated.
In order to minimize the occurrence of impact damage to the tires
of your vehic le, we recommend that you observe the fo llowing
precautions:
• Always maintain recommended inflation pressures . Check your
tire pressure every 2,000 miles (3,000 km) and add air if necessary .
• Drive careful ly 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 . .,_
