Safe driving
on the safety compliance sticker on the left
door jamb. Exceeding permissible weight
standards can cause the vehicle to slide and handle differently .
- Please observe information on safe driving
9 page 179.
A WARNING
To help prevent poisonous exhaust gas from
being drawn into the vehicle, always keep the
rear lid closed while driving.
- Never transport objects larger than those
fitting completely into the luggage area be­ cause the rear lid cannot be fully closed .
- If you absolutely must drive with the rear lid open, observe the following notes to reduce
the risk of poisoning:
- Close all windows,
- Close the convertible top,
- Open all air outlets in the instrument pan-
el,
- Switch off the air recirculation,
- Set the fresh air fan to the highest speed .
A WARNING
.
-
Always make sure that the doors, all win­
dows, the convertible top and the rear lid are
securely closed and locked to reduce the risk
of injury when the vehicle is not being used.
- After closing the rear lid , always make sure
that it is properly closed and locked.
- Never leave your vehicle unattended espe­
cially with the rear lid left open . A child
could crawl into the vehicle through the lug­
gage compartment and close the rear lid be­
coming trapped and unable to get out. Be­
ing trapped in a vehicle can lead to serious
personal injury.
- Never let children play in or around the vehi­
cle.
- Never let passengers ride in the luggage compartment. Vehicle occupants must al­
ways be properly restrained in one of the ve­
hicle's seating positions.

@ Tips
- Air circulation helps to reduce window fog­
ging. Stale air escapes to the outside
through vents in the trim panel, on the left
side of the luggage compartment. Be sure
to keep these slots free and open.
- The tire pressure must correspond to the
load. The tire pressure is shown on the tire
pressure label. The tire pressure label is lo­
cated on the driver's side B-pillar . The tire
pressure label lists the recommended cold
tire inflation pressures for the vehicle at its
maximum capacity weight and the tires that
were on your vehicle at the time it was man­
ufactured. For recommended tire pressures
for normal load conditions , please see chap­
ter ¢page255.
Tie -downs
The luggage compartment is equipped with four
tie-downs to secure luggage and other items.

In a collision, the laws of physics mean that even
smaller items that are loose in the vehicle will
become heavy missiles that can cause serious in­
jury. Items in the vehicle possess energy which
vary with vehicle speed and the weight of the
item . Vehicle speed is the most significant factor.
For example , in a frontal collision at a speed of
30 mph (48 km/h), the forces acting on a 10 lbs
(4.5 kg) object are about 20 times the normal
weight of the item. This means that the weight
of the item would suddenly be about
...

Safety belts
Why safety belts?
Frontal collisions and the law of physics
Frontal crashes create very strong forces for peo­
ple riding in vehicles .
Fig . 153 Unbelted occupants in a veh icle headi ng fo r a wall
Fig. 154 T he vehicle c rashes into the wall
The physical principles are simple. Both the vehi­
cle and the passengers possess energy which var­
ies w ith vehicle speed and body weight. Engi­
neers call this energy "k inetic energy."
The higher the speed of the vehicle and the
greater the vehicle's weight, the more energy
that has to be "absorbed" in the crash.
Vehicle speed is the most significant factor .
If
the speed doubles from 15 to 30 mph (25 to 50
km/h), the energy increases 4 times!
Because the passengers of this vehicle are not us­
i ng safety belts
c::>fig. 153, they will keep moving
at the same speed the vehicle was moving just
before the crash, unti l something stops them -
here, the wall
c::> fig . 154.
The same principles apply to people sit ting in a
vehicle that is involved in a frontal collision . Even
at c ity speeds of 20 to 30 mph (30 to 50 km/h),
the forces acting on the body can reach one ton
188
(2,000 lbs, or 1,000 kg) or more . At higher
speeds, these forces are even greater.
People who do not use safety belts are also not
attached to their vehicle. In a frontal collis ion
they will also keep moving forward at the speed
their vehicle was travelling just before the crash.
Of course, the laws of physics don't just apply to
frontal collisions, they determine what happens
in all kinds of accidents and collisions .
What happens to occupants not wearing
safety belts?
In crashes unbelted occupants cannot stop
themselves from flying forward and being in­
jured or killed . Always wear your safety belts!
Fig. 155 A drive r not wea ring a safety belt is vio len tly
t hrow n fo rward
Unb elted occupants are not able to resist the tre­
mendous forces of impact by holding tight o r
bracing themselves . Without the benefit of safe­
ty restraint systems, the unrestrained occupant
will slam violently into the steering wheel, in­
strument panel, windshield, or whatever else is
i n the way
c::> fig . 155 . This impact w ith the vehi ­
cle inter ior has all the energy they had just be­
fore the crash.
Never rely on a irbags alone for protection . Even
when they deploy, a irbags provide only addit ional
protection. Airbags are not supposed to deploy in
all kinds of accidents. Although your Audi is
equipped with airbags, all veh icle occupants, in ­
cluding the driver, must wear safety belts cor­
rectly in order to minimize the risk of severe in­
ju ry or death in a crash .
Remember too, that airbags will deploy only
once and that your safety be lts are always there
IJJ,,

to offer protection in those accidents in which
airbags are not supposed to deploy or when they
have a lready deployed. Unbelted occupants can
also be thrown out of the vehicle where even
more severe or fatal injuries can occur.
Safety belts protect
People think it's possible to use the hands to
brace the body in a minor collision. It's simply
no t true!
Fig. 156 Drive r is correctly restra ined in a s udde n brak ing

Safety belts used properly can make a big differ­
ence. Safety belts help to keep passengers in
their seats, gradually reduce energy levels ap ­
p lied to the body in an accident , and he lp prevent
the uncon trolled movement tha t can cause seri­
ous injur ies. In addi tion , safety belts reduce the
danger of being thrown out of the veh icle.
Safety belts attach passengers to the car and give
them the benefi t of bei ng slowed down more
gent ly or "softly" through the "give" i n the safe ty
be lts, crush zones and other safety features engi­
neered into today's vehicles . By "absorbing" the
kinetic energy ove r a longer period of time, the
safety belts make the forces on the body more
"to lerable" and less likely to cause injury.
Although these examples are based on a fronta l
coll is ion, safety belts can also substantially re­
duce th e risk of inj ury in other kinds of crashes.
So, whether you're on a long trip or just going to
the corner store, always buckle up and make sure
others do, too . Accident stat istics s how that vehi­
cle occupants properly wearing safety belts have
a lower risk of being in ju red and a much better
chance of s urviv ing a n accide nt. Prope rly us ing
Safet y bel ts
sa fety belts also great ly increases the ability of
the supp lemental airbags to do their job in a col­
li sion . For this reason, wearing a safety belt is le­
gally required in most countries including much
of the United States and Canada.
Although your Audi is equipped with airbags, you still have to wear the safety belts p rovided . Front
airbags, for example, are activated only in some
frontal collisions. The front airbags are not acti­
vated in a ll frontal collisions, i n side and rear col­
lis ions, in rollovers o r in cases where there is not
enough decelerat ion through impact to the front
of the veh icle. The same goes for the othe r air bag
systems in your Aud i. So, always wear yo ur safe ty
belt an d make sure everybody in your vehicle is
prope rly restrained!
Important safety instructions about safety
belts
Safety belts must always be correctly positioned
across the strongest bones of your body.
.,. Always wear safety belts as i llustrated and de ­
scribed in this chapter.
.,. Make sure that your saf ety be lts are always
ready for use and are not damaged.
A WARNING
Not wear ing safety be lts o r wearing t hem im­
p roperly increases the r is k of serious personal
i njury and death . Safety belts can work only
when used correctly.
- Always fasten your safety belts co rrectly be­
fore d riving off and make sure a ll passen­
ge rs a re co rrectly res trained.
- For maximum protection, safety belts must
always be positioned properly o n the body .
- Never strap more than one person, includ­
ing smal l children , into any belt .
- Never p lace a safety belt over a child sitting
on yo ur lap .
- Always keep feet in the footwe ll in front of
the seat while the veh icle is being driven .
- Never let any person ride with the ir feet on
the instrument panel or stick ing out the
window or on the seat.

seat backrests; never place them between
these areas and you or any other person in
the vehicle.
- Never attach objects to the windshield
above the passenger front airbag, such as
accessory GPS navigation units or music
players. Such objects could cause serious in ­
jury in a collision, especially when the air­ bags inflate .
A WARNING
A person on the front passenger seat, espe­
cially infants and small children, will receive
serious injuries and can even be killed by be­
ing too close to the airbag when it inflates.
- Although the Advanced Airbag System in
-
your vehicle is designed to turn off the front
passenger airbag if an infant or a small child
is on the front passenger seat, nobody can
absolutely guarantee that deployment un­
der these special conditions is impossible in
all conceivable situations that may happen
during the useful life of your vehicle.
- The Advanced Airbag System can deploy in accordance with the "low risk" option under
the U .S . Federal Standard if a child that is
heavier than the typical one-year old child is
on the front passenger seat and the other
conditions for airbag deployment are met.
- For its own safety, a child should always ride
properly restrained for its age and size.
Advanced front airbag system
Your vehicle is equipped with a front Advanced
Airbag System in compliance with United States
Federal Motor Vehicle Safety Standard (FMVSS)
208, as well as Canada Motor Vehicle Safety
Standard (CMVSS) 208 as applicable at the time
your vehicle was manufactured.
The front Advanced Airbag System supplements
the safety belts to provide additional protection
for the driv er's and front passenger's heads and
upper bodies in frontal crashes . The airbags in­
flate only in frontal impacts when the vehicle de­
celeration is high enough.
Airbag system
The front Advanced Airbag System for the front
seat occupants is not a substitute for your safety
belts. Rather, it is part of the overall occupant re­
straint system in your vehicle. Always remember
that the airb ag system can only help to protect
you, if you are sitting upright, wearing your safe­
ty belt and wearing it properly . This is why you
and your passengers must always be properly re­
strained, not just because the law requires you to
be.
The Advanced Airbag System in your vehicle has
been certified to meet the "low risk" require­
ments for 3 and 6 year-old children on the pas­
senger side and very small adults on the driver
side. The low risk deployment criteria are intend­
ed to help reduce the risk of injury through inter­
action with the front airbag that can occur, for
example, by being too close to the steering wheel
and instrument p anel when the airbag inflates.
In addition, the system has been certified to
comply with the "suppression" requirements of
the Safety Standard, to turn off the front airbag
for infants 12 months old and younger who are
res trained on the front passenger seat in child re­
straints that are listed in the Standard
~page 218, Child restraints and Advanced front
airbag system .
"Suppression" requires the front airbag on the
passenger side to be turned off if:
- a child up to about one year of age is restrained
on the front passenger seat in one of the rear­
facing or forward-facing infant restraints listed in Federal Motor Vehicle Safety Standard 208
with which the Advanced Airbag System in your
vehicle was certified . For a listing of the child
restraints that were used to certify your vehi­
cle's compliance with the US Safety Standard

- When a person is detected on the front passen­
ger seat that has an electrical capacitance that
is more than the total electrical capacitance of
a child that is about 1 year old restrained in one
of the rear-facing or forward-facing infant re­
straints (listed in Federal Motor Vehicle Safety
Standard 208 with which the Advanced Airbag
System in your vehicle was certified), the front

airbag on the passenger side may or may not
deploy.
The
PAS SENGER AIR B AG OFF ~; light comes o n
when the e lectron ic control un it detects a total
e lectrica l capacitance on the front passenger seat
that requires the front airbag to be turned
off . If
the
PASSENGER AIR BAG OFF '1; light does not
come on, the front airbag on the passenger side has not been turned
off by the control unit and
can deploy if the control unit senses an impact
that meets the conditions stored in its memory .
If the tota l electrical capac itance registered on
the front passenger seat is more than that of a
typical 1 year -old, but less than the weight of a
small adult , the front airbag on the passenger
side may deploy (the

For exampl e, th e airbag may d eploy if:
- a small child that is heavier than a typical 1
year-old ch ild is on the front passenger seat
(regardless of whether the child is in one of the
ch ild seats listed
r=;,page 218),
- a chi ld who has outgrown child restraints is on
the front passenger seat .
If the front passenger airbag is turned off , the
P ASS ENGER AIR BA G OFF~; light in the head­
liner will come on and stay on .
I f the front passenger airbag dep loys, the Feder ­
a l Standard requires the airbag to meet the "low
risk" deployment criteria to help reduce the risk
of injury through interaction with the airbag.
"Low risk" deployment occurs in those crashes
that take place at lower decelerations as def ined

front passenger's seat:
- Always make sure the forward -fa cing sea t
has bee n des igned and certified by its man ­
ufacturer for use on a front seat with a pas ­
senge r front and side airbag.
- Never put the fo rward -facing chi ld restrain t

-Never install seat covers or replacement
upholstery over the front seatbacks that
have not been specifically approved by
Aud i.
- Never use add itiona l seat cushions that
cover the areas where the s ide airbags in­
flate.
- Damage to the origina l seat covers or to
the seam in the area of the side airbag module must always be repaired immedi­
ately by an authorized Audi dealer.
- The airbag system can deploy only once . Af­
ter an airbag has been deployed, it must be
rep laced with new rep lacement parts de­
signed and approved especially fo r you r
Audi mode l version. Replacement of com­
plete airbag systems or airbag components
must be performed by qualified workshops
only . Make sure that any airbag service ac­
tion is entered in your Audi Warranty

Maintenance booklet under AIRBAG RE­
PLACEMENT RECORD.
- For safety reasons in severe accidents, the
alternator and starter are separated from
the vehicle battery with a pyrotechn ic circuit
interrupter.
-Work on the pyrotechnic circu it interrupt­
er must only be performed by a qualified
technicians who have the experience, in­
formation and special tools necessary to perform the work safely.
-If the vehicle or the circuit interrupter is
scrapped, all app licab le safety precautions
must be followed.

Airbag syste m
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag System
performs in a crash. For example, using tire-rim
combinations not approved by Audi, lowering the
vehicle, changing the stiffness of the suspension, including the springs, suspension struts, shock
absorbers etc . can change the forces that are
measured by the airbag sensors and sent to the
electronic cont rol u nit. Some suspension c hanges
can, for example, increase the fo rce leve ls meas­
u red by the sensors and make t he a irbag system
deploy in crashes in which it wou ld not deploy if
the changes had not been made. Other kinds of
changes may reduce the force levels measured by
the sensors and prevent the a irbag from deploy­
ing when it should.
A WARNING
-
Changing the vehicle's suspension including use of unapproved tire-rim combinations can
change Advanced Airbag perfo rmance and in­
crease the risk of serious personal injury in a
crash.
- Never install suspension components that
do not have the same performance charac­
ter istics as the components o riginally instal­
led on your vehicle .
-Never use tire-rim combin ations that have
not been approved by Audi .

Child safety
The vehicle 's safety belts alone will not fit most
chi ldren until they are at least 4
ft 9 in (57 in/
1.45 m) tall and weigh about 80 lbs (36 kg) .
Booster seats raise these children up so that the
safety belt will pass properly 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 restrain
a child on a booster seat .
.. The shoulder belt must lie as close to the cen­
ter of the child's collar bone as poss ible and
must lie flat and s nug 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 tight ­
en if necessary .
Chi ldren up to at least 8 years old (over 40 lbs or
18 kg) are best protected in chi ld safety seats de­
signed for their age and weight . Experts say that
the skeleta l structure, particularly the pelvis, of
these children is not fully developed, and they
must not use the vehicle safety belts without a
suitable child restraint.
It is usually best to put these children in appro­
priate booster seats. Be sure the booster seat
meets all applicable safety standards .
Booster seats raise the seating position of the
child and repos ition both the lap and shoulder
parts of the safety be lt so that they pass across
the child's body in the right places. The rout ing of
the belt over the child's body is very important
for the child's protection, whether or not a boos­
ter seat is used.
Never use the lap belt portion of the vehicle's
safety belt alone to restrain any child, regardless
of how big the child is. Always remember that
chi ldren do not have th e pronounced pelvic struc­
ture required fo r the proper function of lap belt
port ion of the vehicle's three point lap and
shoulder belts. The child's safety absolute ly re ­
quires that a lap belt portion of the safety belt be
fastened snugly and as low as possible around the pelvis . Never let the lap belt portion of the
224
safety belt pass ove r the child's stomach or abdo­
men .
In a crash, airbags must inflate w ith in a blink of
an eye and with considerable force. In order to do
its job, the airbag needs room to inflate so that it
will be there to protect the occupant as the occu ­
pant moves forward into the airbag .
A ve hicle occ upant who is o ut of pos it io n and too
close to the airbag gets in the way of an inflating
airbag . When an occupant is too close, he or she
will be struck vio lent ly and w ill rece ive serious or
possibly even fatal injury.
In order for the airbag to offer protection, it is
important that all vehicle occupants, especially
any ch ildren, who m ust be in the front seat be­
cause of exceptional c ircumstances, be properly
restrained and as far away from the airbag as
possible . By keeping room between the child 's
body and the front of the passenger compart­
ment, the a irbag can inflate completely and pro­
v ide supplementa l protection in certa in frontal
collisions.
_& WARNING
Not using a booster seat, using the booster
seat improperly, incorrect ly installing a boos­
ter seat or using the ve hicle safety belt im­
properly increases the r isk of serious personal
injury and death in a collision or other emer­
gency situation. To he lp reduce the risk of se­
rious personal injury and/or death:
- The shou lder belt must lie as close to the
center of the child' s collar bone as possible
and must 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 that the belt lies flat and snug .
P ull on the belt to tighten if necessary .
- Failur e to properly route safety belts over a
child's body will cause severe injuries in an
accident or other emergency situation
¢page 187.
- The rear side of the child safety seat should
be positioned as close as possible to the
backrest on the ve hicle seat .
-

Wheels
Because the spare tire* is differ­
ent from the regular tires instal­ led on the vehicle (such as winter
tires or wide tires), only use the
spare tire* temporarily in case of
emergency and drive carefully
while it is in use. It should be re­ placed with a regular tire as soon
as possible.
Applies to: vehicles with all wheel
drive: all four wheels must be
equipped with tires that are the
same brand and have the same
construction and tread pattern so
that the drive system is not dam­
aged by different wheel speeds.
For this reason, in case of emer­
gency, only use a spare tire* that
is the same circumference as the
regular tires.
& WARNING ~ -
-Only use tire/rim combina­
tions and suitable wheel bolts
that have been approved by
Audi. Otherwise, damage to
the vehicle and an accident could result.
-For technical reasons, it is not
possible to use tires from oth­
er vehicles - in some cases,
you cannot even use tires from
the same vehicle model.
252
-Make sure that the tires you
select have enough clearance
to the vehicle. Replacement
tires should not be chosen simply based on the nominal
size, because tires with a dif­
ferent construction can differ greatly even if they are the
same size. If there is not
enough clearance, the tires or
the vehicle can be damaged and this can reduce driving
safety and increase the risk of
an accident.
-Only use tires that are more
than six years old when abso­
lutely necessary and drive
carefully when doing so.
-Do not use run-flat tires on
your vehicle. Using them when not permitted can lead to ve­
hicle damage or accidents.
- If you install wheel covers on
the vehicle, make sure they al­ low enough air circulation to
cool the brake system. If they
do not, this could increase the
risk of an accident.

Tire pressure monitoring system
(J_) General notes
Each tire, incl uding the spare (if provided),
should be checked month ly when co ld and inflat­
ed to the inf lation pressure recommended by the
ve hicle manufacturer on the vehicle placard or
tire inflat ion pressure label. (If your vehicle has
tires of a d ifferent s ize tha n the s ize indicated on
the veh icle placa rd or t ire inflation pressure la­
be l, you s hou ld determine the prope r tir e infla­
tion pressure fo r th ose tires).
As an added safety feature, your ve hicle has been
equ ipped w ith a t ire pressu re monito ring system
(TPMS) that ill uminates a low tire p ress ure tell­
tale whe n one or more of yo ur t ires is sign ificant ­
l y unde r-infla ted. Accord ingly, whe n the low tire
p ressure tellta le illuminates, yo u should stop and
check your tires as soon as possible, and inflate
them to the proper press ure. D riving on a signifi ­
cantly under-inflated tire causes the tire to ove r­
h eat and can lead to t ire failure. Under-inflation
a lso reduces fuel efficiency and ti re tread life,
and may affect the veh icle's handling and stop­
p ing ability .
P lease note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re­
sponsib il ity to ma inta in correct tire pressure,
even if u nder-inflation has not reached t he leve l
to tr igger illum inat io n of t he TPM S low tire p res ­
sure telltale.
Your veh icle has also been equ ipped w ith a TPMS
malfunct ion ind icator to indicate when the sys­
tem is not operat ing properly. The TPMS ma l­
f u nction ind icator is combined w ith the low tire
p ressure tellta le. Whe n the system det ects a
mal function, the te lltale wi ll flash fo r approxi ­
mate ly one mi nute and then remain continuous ly
illum inated. This sequence will continue upon
subseq uent ve hicle start-ups as long as the ma l­
function ex ists .
W hen t he malfunctio n indicator is ill uminated,
the system may not be ab le to detect or signa l
low t ire press ure as intended. TPMS ma lfunctions
may occur for a var iety of reasons, including the
Wheels
insta llation o f replacement or alternate tires or
whee ls on the vehicle that prevent the TPMS
from functioning p roperly . Always check the
TPMS ma lfunction te lltale after replac ing one or
more tires or wheels on you r vehicle to ensure
t h at the rep lacement or a lternate tires a nd
wheels allow t he TPMS to continue to function
prope rly.
