Do not use the diagnostic connector for
personal use. Incorrect usage can cause
malfunctions, which can increase the risk
of a coll is ion!
Electronic speed limiter
-
Your veh icle may be factory equipped with
tires that are rated for a maximum speed of
130 mph (210 km/h) . T his is less than the
maximum speed o f yo ur vehicle. To reduce the
risk of s udden tire failure and loss o f control if
the vehicle is operated at excessive speeds,
your vehicle also has an electronic speed limit­
er. The electronic speed limiter prevents your
veh icle from going faster than the tire speed
rating. For more informat ion ¢
page 207 .
If the engine control unit rece ives fau lty vehi­
cle roadspeed signa ls, the Ma lfunction Indica­
tor Light (MIL)

Climate controls
Controls
The air conditioning automatically maintains the selected temperature in the vehicle interior
throughout each season .
Fig. 68 Climate contro ls
We recommend the following sett ing :
> Rotate the knob ¢ fig. 68 @to the right to
switch on the air conditioning .
> Set the temperature to 72 °F (22 °() .
> Press the !AUTO I ¢ fig . 68 button .
Using the previously recommended setting is
the quickest way to achieve a comfortable cli ­
mate in the vehicle . This setting should there­
fore only be changed when persona l comfort
l eve ls or ce rtain circumstances requi re it .
The climate controls are a combination of au ­
tomatic heating and ventilation systems and a
coo ling system which dehumidifies and coo ls
the air ins ide the veh icle.
The climate controls automatically maintain a temperature once it has been set . The tem­
perat ure of the air from the vents, fan speed
(air vol ume) and ai r d ist ribution are also auto­
mat ical ly adjusted . The system also takes into
account strong s unshine so that manua l ad­
justment is not necessary. So in almost all cases,
a ut om at ic mode offers the best cond i­
tions for the comfort of the occupants at all
times of the year ¢
page 69.
Please not e:
In cooling mode , relative humidity in the inte­
rior is reduced . This prevents the w indows
from fogg ing up.
When relative hum idity and temperatures
outside are high ,
conden sati on can drip from
the a ir condition ing evaporator and form a
pool of water under the vehicle. This is normal
and not an ind ication of a leak!
When outs ide temperatures are low, the fan
does not switch to a higher speed until the
coolant has reached an adequate tempera ­
tu re, with the exception of the defrost set­
t ing.
When accelerating at wide-open throttle, the air conditioning compressor is temporarily
switched off to ma intain full engine power .
In order to ensure engine cooling under ex­
treme engine loads, the compressor is switch­ ed off if coolant temperatures climb too high.
Funct ions are set by turning the rotary knob
or switched on and off by tapp ing the buttons.

Pollutant filter
The po llutant filter (particle filter) ensures
that contaminants in the outs ide a ir (such as
dust or pollen) are greatly reduced or stop­ ped. The air is also f iltered in recirculation
mode .
The pollutant filter element must be changed according to the intervals spec ified in the
maintenance schedule so that the air cond i­
tioning system's pe rformance is not adversely
affected.
If the filter's effect iveness is weakened by
driving the vehicle in areas with heavily pollut­
ed outs ide a ir, the fi lter element should also
be changed in between the listed services.
,&. WARNING
For safety reasons, it is impo rtant that all
w indows are free o f ice, snow, a nd conden­
sation . Only then is good visib ility ensured .
Please fami liarize yourse lf wit h the correct
operation of the air conditioning and how
to deh umidify/defrost the windows.

A WARNING
-Indiv iduals with reduced sens itivity to pain
or temperature could develop burns when
using the seat heating function . To reduce
the r isk of injury, these ind ividuals should
not use seat heating.
~ Note
To avoid damage to the heating elements
in the seats, do not kneel on the seats or
place heavy loads on a small area of the
seat.

112 Airbag system
-An improperly installed child restraint
can interfere with the airbag as it de ­
ploys and seriously injure or even kill the
child -even with an Advanced Airbag
System .
- Always carefully follow the manufactur­
er's instructions provided with the child
safety seat or carrier.
- Never place additional items on the seat
that can increase the total weight regis­ tered by the weight-sensing mat and can
cause i njury in a crash .
Front airbags
Description of front airbags
The airbag system con provide supplemental
protection to properly restrained front seat
occupants.
Fig. 104 Location of driver airbag: in stee ring wheel
Fig. 105 Location of front passenger's air bag : in the in ­
st rume nt panel
Your veh icle is equipped with an "Advanced
A irbag System" in compliance w ith United
States Federal Motor Vehicle Safety Standa rd
(FMVSS) 208 as applicab le at the time your
vehicle was manufactured. The safety belts
for the front seats have "pretensioners" that
help to take slack out of the belt system. The pretensioners are a
lso activated by the e lec­
tronic contro l unit for the airbag system.
T he front safety belts also have lo ad lim ite rs
to help reduce the fo rces applied to the body
in a crash .
T he airbag for the d river is in the steering
wheel hub~
fig. 104 and the ai rbag for the
fron t passenger is in the instrument panel
~ fig. 105 . The general locat ion of the ai rbags
is marked "AIRBAG".
T he re is a lot you need to know about t he a ir­
bags in you r vehicle. We urge yo u to read the
detailed information abo ut airbags, safety
belts and child safety in this and the other
chapters that make up the owner's literature .
P lease be sure to heed the WARNINGS - they
are extremely important for your safety and
the safety of your passengers, especially in ­
fants and small children .
A WARNING
Never rely on airbags alo ne for protection .
- Even when they deploy, airbags provide
only supplemental protect ion.
- Airbag work most effective ly when used
with properly worn safety belts.
- Therefore, always wear your safety belts
a nd make sure that eve rybody in your ve­
h icle is p roperly rest rained.
A WARNING
A person on the front passenger seat, es­
pec ially infants and sma ll children, w ill re­
ceive serio us injuries and can even be kil-
l ed by be ing too close to the ai rbag when
i t inflates .
- Al tho ugh the Advanced Airbag System in
your veh icle is designed to tur n
off the
front passenge r airbag if an infant or a
small child is on the front passenger
seat, nobody can absolutely guarantee
that deployment under these special
conditions is impossible in all conceiva­
b le situat ions 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 de­
ployment are met .
-Accident statistics have shown that chil­
dren are generally safer in the rear seat
area than in the front seating position.
- For their own safety, all children, espe­
cially 12 years and younger, should al­
ways ride in the back properly restrained
for their 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
208 as applicable at the time your vehicle was
manufac tured.
The front Advanced Airbag System supple­ ments the safety belts to provide additional
protection for the driver's and front passeng­
er's head s and upper bodies in frontal crashes.
T he airbags inflate only in frontal impacts
when the vehicle deceleration is high enough.
T he front Advanced Airbag System for the
front seat occupants is not a substitute for
your safety belts . Rather, it is part of the over­
all occupant restraint system in your vehicle.
Always remember that the airbag system can
only help to protect you, if you are sitting up­
right , wearing your safety belt and wearing it
properly . This is why you and your passengers
must always be properly restrained, not just
because the law requires you to be.
The Advanced Airbag System in your vehicle has been certified to meet the "low risk" re­
quirements for 3 and 6 year-old children on
the passenger side and very small adults on
the driver side. The low risk deployment crite­
ria are intended to help reduce the risk of in­
jury through interaction with the front airbag that can occur, for example, by being too
Airbag system 113
close to the steering wheel and instrument
panel 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 restrained on the front passenger
seat in child restraints that are listed in the
Standard ¢
page 132 , Child restraints and
Advanced Airbags .
"Suppression" requires the front airbag on the
passenger side to be turned off if:
- a child up to about one year of age is re­
strained 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 Ad­
vanced Airbag System in your vehicle was
certified . For a listing of the child restraints
that were used to certify your vehicle's com­ pliance with the US Safety Standard
¢page 132,
-weight less than a threshold level stored in
the control unit is detected on the front pas­
senger seat.
When a person is detected on the front pas­ senger seat, weighing more than the total
weight of a child that is about 1 year old re­
strained in one of the rear-facing or forward­
facing infant restraints (listed in Federal Mo­
tor Vehicle Safety Standard 208 with which
the Advanced Airbag System in your vehicle
was certified), the front airbag on the passen­ ger side may or may not deploy.
The
PASSENGER AIR BAG OFF light comes on
when the electronic control unit detects a to­
tal weight on the front passenger seat that re­
quires the front airbag to be turned off. If the
PASSENGER AIR BAG OFF 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 total weight on the front passenger
seat is more than that of a typical 1 year-old , ..,. •

A WARNING
Sitting in the wrong position can increase
the risk of serious injury in crashes.
- To reduce the risk of injury when the air­
bags inflate, the driver and passengers
must always sit in an upright position,
must not lean against or place any part
of the ir body too close to the area where
the a irbags are located .
- Occupants who are unbelted, out of posi ­
t ion or too close to the airbag can be se­
riously injured by an airbag as it unfolds
with great force in the blink of an eye
~page 110.
A WARNING
-
A child in a rearward -facing child sa fety
seat insta lled on the front passenger seat
w ill be seriously injured and can be ki lled if
the front airbag inflates - even wit h an Ad­
vanced Airbag System.
-The inflating ai rbag will hit the child
safety seat or infant carrier with g reat
force and w ill smash the ch ild safety seat
and child against the backrest, ce nter
arm rest, door o r roof.
- Always install rear-facing child safety
seats on the rear seat.
- If you must install a rearward facing child safety seat on the front passenger
seat because of exceptional circ umstan­
ces and the
PASSENGER AIR BAG OFF
light does not come on and stay on, im­
med iately install the rea r-facing child
safety seat in a rear seating po sition and
have the airb ag sys tem inspec ted by you r
Audi dealer .
A WARNING
Objects between you and the a irbag will
increase the risk of in jury in a c rash by in­
terfering with the way the airbag unfolds
or by being pushed into yo u as the a irbag
inf lates. -
Never hold things in you r hands o r on
your lap when the veh icle is in use.
- Never transpo rt items on or in t he a rea
of the front passenger seat. Objects
could move into the area of the front air­
bags during braking or other sudden ma­
neuver and become dangerous p rojec­
tiles that can cause ser ious personal in­
jury if the a irbags inf late .
- Never p lace or attach accesso ries o r oth ­
er objects (such as cup hold ers, te le­
phone b ra ck ets, large, heavy or bulky ob­
jects) on the doors, ove r o r ne ar the are a
marked "AIRBAG" on the s teer ing whee l,
instr ument panel, sea t bac krests o r be ­
tween those areas and yourself. These
objects could ca use in jury in a crash, es­
pecially when the airbags inflate.
- Never recline the front passenger 's seat
to transport objects. Items can a lso
move into the area of the s ide airbag or
the front a irbag during braki ng or in a
sudden maneuve r. Objects near the air­
bags can become projectiles and cause
in jur y, partic ularly when the seat is re­
clined.
- Never tilt the front passenger seat back­
rest forwar d w hen the vehi cle is moving.
An in flating airbag w il l force the ba ck­
rest backwar d an d can injure rear seat o c­
cupants.
A WARNING
=
The fine dust create d when air bags deploy
can cause breathing prob lems fo r people
with a history of asthma or other breath­
i ng cond itions.
- To reduce the risk of breathing problems ,
those with asthma or other respiratory
conditions shou ld get fresh air right
away by getting o ut o f the veh icle or
open ing windows or doors.
- If you are in a collision in which airbags
deploy , wash your hands and face with
mild soap and wate r before eating .
- Be ca reful not to get the dust into your
eyes, o r into any c uts or sc ratches .
