Description of front airbags
The airbag system can provide supplemental
protection to properly restrained front seat occu­
pants .
Fig. 121 Location of d river airbag : in steer ing w hee l
Fig. 122 Location of front passenger's airbag: in the in­
strument panel
Your veh icle is equipped with an "Advanced Air­
bag System" in compliance with Un ited 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
safety belts for the seats have "pretensioners"
that help to take slack out of the belt system .
The pretensioners are also activated by the elec­
tronic control unit for the airbag system.
The front safety be lts also have load limiters to
help reduce the forces applied to the body in a
crash.
The airbag for the driver is in the steering wheel
hub <=>
fig. 121 and the airbag for the front pas­
senger is in the instrument panel
<=>fig. 122. The
general location of the airbags is marked "AIR­
BAG".

There is a lot you need to know about the airbags
in your vehicle . We urge you to read the detai led
i nformation about airbags, safety belts and ch ild
safety in this and the other chapters that make
up the owner's literature. Please be sure to heed
the WARNINGS -they are extremely important
for your safety and the safety of your passengers,
especially infants and small children .
.&_ WARNING -
Never rely on airbags alone for protection.
- Even when they deploy, airbags provide only
supp lemental protection.
- Airbag work most effectively when used
with properly worn safety belts .
- Therefore, always wear your safety belts and make sure that everybody in your vehicle is
properly restrained .
.&_ WARNING
A person on the front passenger seat, espe­
cially infants and small ch ildren, wi ll receive
serious injuries and can even be killed by be­
ing too close to the airbag when it inf lates.
- 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
heav ier than the typical one-year old ch ild is
on the front passenger seat and the other
conditions for airbag deployment are met.
- Accident statistics have shown that children
are generally safer in the rear seat area than
in the front seating pos ition.
- For their own safety, all children, especially
12 years and younger, should always ride in
the back properly restrained for their age
and size.

exceptional circumstances and the
PASS ENGER AIR BAG OFF light does not
come on and stay on, immed iately install
the rear-fac ing ch ild safety seat in a rear
seating pos it ion and have the airbag system
inspected immediately by your Audi dealer .
A WARNING
If, in exceptio nal circumstances, you must in­
stall a forward-facing chi ld restraint on the
front passenger's seat:
- Always make sure the forward-fac ing seat
has been designed and ce rtified by its man­
ufact urer fo r use on a front seat with a pas­
senger front and side airbag .
- Always follow the manufact urer's instruc­
tions prov ided with the ch ild safety seat or
carrier.
- Always move the passenger seat into its
rearmost position in the seat's fore and aft
adjustment range, as far away from the air­
bag as possib le before installing the child
restraint. The backrest must be adjusted to
an upr ight position.
- Always make sure that the
PA SSENGER AIR
BAG OFF
light comes on and stays on all the
t ime whenever the ignition is switched on.
{D) Tips
Always replace chi ld restraints that were in­
stalled in a vehicle dur ing a crash . Damage to
a child restraint that is not visible could cause
it to fail in another collision situation.
Advanced front airbag system and children
Your veh icle is equipped with a front "Advanced
Airbag System " in compliance w ith United States
F edera l Moto r Vehicle Safety Standard (FMVSS)
208, as well as Canada Motor Ve hicle Safe ty
Stand ard (CMVSS) 208 as appli cable at the t ime
your vehicle was manufactured .
The Advanced Airbag system in your ve hicle has
been ce rtified to meet the "low-risk " requ ire­
ments for 3 -and 6-year old children on the pas­
senger side and small adults on the driver side .
The low risk deployment criteria are intended to
Ch ild safety
reduce the risk of injury through interaction with
the airbag that can occur, for example, by being
too close to the steering wheel and instr ument
panel when the airbag inflates. In addition, the
system has been cert ified to comply with the
"suppression" requirements of the Safety Stand ­
ard, to turn off the front airbag for infants up to
12 months who are restrained on the front pas­
senger seat in ch ild rest raints that are lis ted in
the S tanda rd .
Even thoug h your veh icle is equipped with an Ad­
vanced Airbag system, all ch ildren, especially
those 12 yea rs and younger, sho uld a lways ride
i n the back seat properly restra ined for their age
and size . The airbag on the passenger side makes
the front seat a potentia lly dangerous p lace for a
child to ride. The front seat is not the safest place
for a ch ild in a forward-fac ing ch ild safety seat. It
can be a very dangerous place for an infant or a
larger ch ild in a rearward-facing seat .
Advanced Airbags and the weight -sensing
mat in the front seat
T he Advanced A irbag System in you r vehicle de­
tects the presence of a n in fan t or child in a ch ild
restra int on the front passenger seat using the
weight-sensing mat in the seat cushion and the sensor below the safety belt latch on the front
passenger seat that measures the tension on the
safety belt.
The weight-sensing mat measures total weight
of the child and the chi ld safety seat and a child
blanket on the front passenger seat. The weight
on the front passenger seat is related to the de­
s ign of the child restra int and its "footprint" , the
s ize and shape of the bottom of the c hild re ­
straint as it s its on the seat. The weight of a chi ld
r estra int and its "footprint " va ry for different
k inds of child restra ints and for the different
models of the same kind of ch ild rest raint of ­
fered by child restraint manufacturers.
T he weight ranges for the individ ual types,
makes and mode ls of chi ld restrain ts that the
N HT SA has spec ified in the Safety Standard to­
gether with the weight ranges o f typical infants
and typical 1 year-old chi ld have been stored in .,.

Steering recommendation
The ESC helps to stabilize the veh icle by changing
the steering torque.
Selective wheel torque control
Selective wheel torque control is used when driv ­
i n g on curves . The front wheel on the inside of
the c urve or both wheels on the inside of the
curve are braked selectively as needed. This al­
lows more precise driving in curves.
Automatic post-collision braking system
The "Automatic post-collision brak ing system"
can help to reduce the r isk of slid ing and of other
coll is ions after an accident . If the airbag control
module detects a collision above a certain vehicle
speed, the vehicle is braked by the ESC.
The vehicle does not brake automatically if :
- the driver presses the accelerator pedal, or
- the braking force generated by the pressed
brake pedal is greater than the braking force
that would be initiated by the system, or
- the ESC, the brake system or the vehicle electri­
cal system are not functioning.
A WARNING
- The ESC and its integrated systems cannot
overcome the limits posed by natural physi-
Switching on and off
cal laws. This is especially important on slip­
pery or wet roads. If the systems beg in act­
ing to stabilize your vehicle, you should im­
mediately alter your speed to match the
road and traffic conditions. Do not let the
increased safety provided tempt you into
taking risks. This could increase your risk of
a collision.
- Please note the risk of a collision increases
when dr iv in g fast, especially through curves
and on slippery or wet roads, and when dr iv­
ing too close to objects ahead. The ESC and
its integrated systems cannot always pre­
vent collisions -there is still a risk of acci­
dents!
- Press the accelerator peda l carefully when
accelerating on even, slippery surfaces such
as ice and snow. The drive wheels can spin
even when these control systems are instal­
led and this can affect driving stability and
increase the risk of a collision .
@ Tips
-ABS and ASR only function correctly when
all four wheels are equipped with identical
tires. Different tire sizes can lead to a reduc­
tion in engine power.
- You may hear noises when the systems de­
scribed are working.
£SC turns on automatically when you start the engine .

The ESC is designed to function in levels. Depend­
i ng on the level that is selected, the stabilization
function of the ESC is limited or switched off. The amount of stabilization control will differ de­
pending on the level.
The following examples are unusual situations
where it may make sense to switch offroad mode
on to allow the wheels to spin:
- Rocking the vehicle to free it when it is stuck
- Dr iving in deep snow or on loose ground

New tires or wheels
Audi recommends having all work
on tires or wheels performed by
an authorized Audi dealer or au­
thorized Audi Service Facility.
These facilities have the proper knowledge and are equipped with
the required tools and replace­
ment parts.
.,.New tires do not yet have the
optimum adhesion properties. Drive carefully and at moderate
speeds for the first 350 miles (500 km) with new tires .
.,.Use tires of the same construc­
tion, size (rolling circumference)
and as close to the same tread
pattern as possible on all four
wheels .
198
.,.Do not replace tires individually.
At least replace both tires on the
same axle at the same time.
.,.Audi recommends that you use
Audi Original equipment tires. If
you would like to use different
tires, please note that the tires may perform differently even if
they are the same size ¢
,&.
.,. If you would like to equip your
vehicle with a tire/rim combina­
tion that is different from what
was installed at the factory, con­
sult with an authorized Audi dealer or authorized Audi Service
Facility before making a pur­
chase ¢&, .
If the spare tire is different from
the regular tires installed on the
vehicle -for example, if winter
tires or wide tires are installed -
then only use the spare tire tem­
porarily in case of emergency and
drive carefully while it is in use. It
should be replaced with a regular
tire as soon as possible.
On
all wheel drive vehicles, 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 damaged by .,.

different tire speeds. For this rea­son, in case of emergency, only
use a spare tire that has 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.
-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.
Wheels
-Only use tires that are more
than 6 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.
