& WA RNING (c on tinued )
• Never let a child stand or kneel on an y seat , for e xample the
front seat.
• Never let a child ride in the cargo area of your vehicle .
• Always remember that a child leaning forward , sitting s ide­
ways or out of position in any way during an accident can be struck
by a deploying airbag . This will result in se rious personal injury or
death.
• If you must install a booster seat on the front passenger seat
because of exceptional circumstance s the PASSENGER AIR BAG
OFF light must come on and stay on , whenever the ign ition is
switched on.
• If the PASSENGER AIR BAG OFF l ight does not come on and
s tay on , perform the checks described =>

T he safety belts emergency locking retractors for the rear seats
safety belts and for the front passenge r's se at safety belt have a
convertible locking retractor for child restrai nts. The safety belt must
be locked so that belt webbing canno t unreel. The retra ctor can be
act ivated to lock the safety belt and prevent the safety belt webb ing
fr om loosen ing up du ring normal dr iv ing. A child sa fe ty sea t can on ly
be properly installed when the safety belt is locked so that the child
and child safety sea t will s tay in place .
Always remembe r: Even tho ugh yo ur vehicle is equipped w ith a n
Advanced Airbag system, all ch ildren, espec ia lly those 12 yea rs and
younge r, should a lways ride in t he back seat properly res tra ined for
their age and size.
& WARNING
Improperly in stalled child safety seats increase the risk of serious
personal injury and death in a collision .
• Always make sure that the safety belt retractor is locked when
installing a chi ld safety seat . An unlocked safety belt retractor
cannot hold the child safety seat in place during normal driving or
in a crash .
• Always buckle the child safet y seat firmly in place even if a
child is not sitting in it. A loose child safety seat can fly around
during a sudden stop or in a colli sion.

& WARNING (cont inued)
• If the backrest is not securely latched, the child and the child
restraint will be thrown forward together with the backrest and
will strike parts of the vehicle interior. The child can be seriously
injured or killed.
• Never install rear-facing child safety seats or infant carriers on
the front passenger seat. A child will be seriously injured and can be killed when the passenger airbag inflates.
• The inflating airbag will hit the child safety seat or infant
carrier with great force and will smash the child safety seat and
child against the backrest, center armrest, door or roof .
• Always install rear-facing child safety seats or infant carriers
on the rear seat.
• Forward-facing child safety seats or infant carriers installed on
the front passenger's seat may interfere with the deployment of
the airbag and cause serious injury to the child.
• It is safer to install a forward -facing child safety seat on the
rear seat.
• Always read and heed all WARNINGS whenever using a child
restrained in a vehicle is being used~
page 219. Special precau­
tions apply when installing a child safety seat on the front
passenger seat~
page 199, "Child restraints on the front seat -
some important things to know".
L1}. WARNING
Always take special precautions if you must install a forward or
rearward -facing child restraint on the front passenger's seat in
exceptional situations:
• Whenever a forward or rearward-facing child restraint is
installed on the front passenger seat, the PASSENGER AIR BAG
OFF light must come on and stay on whenever the ignition is
switched on.
& WARNING (co ntinued )
• If the PASSENGER AIR BAG OFF light does not come on and
stay on, perform the checks described
~ page 208, "Monitoring
the Advanced Airbag System".
• Take the child restraint off the front passenger seat and install
it properly at one of the rear seat positions if the PASSENGER AIR
BAG OFF light does not stay on whenever the ignition is switched
on.
• Improper installation of child restraints can reduce their effec­
tiveness or even prevent them from providing any protection.
• An improperly installed child restraint can interfere with the
airbag as it deploys and seriously injure or even kill the child.
• Always carefully follow the manufacturer's instructions
provided with the child safety seat or carrier.
• Never place additional items on the seat that can increase the
total weight registered by the weight-sensing mat and can cause injury in a crash.
L1}. WARNING
Forward-facing child restraints:
• Always make sure the forward-facing seat has been designed
and certified by its manufacturer for use on a front seat with a
passenger front and side airbag .
• Never put the forward-facing child restraint up, against or very
near the instrument panel.
• Always move the passenger seat into its rearmost position in
the seat's fore and aft adjustment range, as far away from the airbag as possible before installing the forward-facing child
restraint . The backrest must be adjusted to an upright position.
• Make sure that the PASSENGER AIR BAG OFF light comes on
and stays on all the time whenever the ignition is switched on . _.

Child Safety -
-------------------"'---
& WARNING
Rearward-facing child restraints:
• A child in a rearward-facing child safety seat installed on the
front passenger seat will be seriously injured and can be killed if
the front airbag inflates -even with an Advanced Airbag System.
• The inflating airbag will hit the child safety seat or infant
carrier with great force and will smash the child safety seat and
child against the backrest, center armrest, door or roof.
• Always be especially careful if you must install a rearward
facing child safety seat on the front passenger seat in exceptional
circumstances.
• A tight tether strap on a rearward-facing child restraint
attached to the front passenger seat can put too much pressure on
the weight-mat in the seat and register a heavier weight in the
Advanced Airbag System. The heavier weight registered can make
the system work as though an adult were on the seat and deploy
the Advanced Airbag when it must be suppressed causing serious
or even fatal injury to the child.
• 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, immediately install the rear-facing child safety seat in a
rear seating position and have the airbag system inspected by
your Audi dealer. •
Activating the convertible Locking retractor
Use the convertible locking retractor to secure a child
restraint.
Always heed the child safety seat manufacturer's instruc­
tions when installing a child restraint in your vehicle. To acti­
vate the convertible locking retractor:
Controls and equip­
ment Safety first Vehicle operation
-
Place the child restraint on a seat, preferably on the rear
seat.
- Slowly pull the belt
all the way out.
- Route it around or through the child restraint belt path
=>& .
- Push the child safety seat down with your full weight to
get the safety belt really tight.
- Insert the belt tongue into the buckle for that seating
position.
- Guide the safety belt back into the retractor until the belt
lies flat and snug on the child safety seat.
- You should hear a "clicking" noise as the belt winds back
i nto the inertia reel. Test the convertible locking retractor
by pulling on the belt. You should no longer be able to pull
the belt out of the retractor. The convertible locking
retractor is now activated.
- Make sure that the red release button is facing away from
the child restraint so that it can be unbuckled quickly.
- Pull on the belt to make sure the safety belt is properly
tight and fastened so that the seat cannot
move forward
or sideways more than one inch (2.S cm).
& WARNING
Using the wrong child restraint or an improperly installed child
restraint can cause serious personal injury or death in a crash.
• Always make sure that the safety belt retractor is locked when
installing a child safety seat. An unlocked safety belt retractor
cannot hold the child safety seat in place during normal driving or
in a crash. ._

fore-and-aft and lateral directions, the brake pressure and the
steering angle are all measured.
The direction in which the driver wishes to travel is determined with
the aid of the steering angle and vehicle speed and is continually
compared with the actual behavior of the vehicle. If the two do not
match, for example , when the vehicle starts hydroplaning on a wet
road, ESP will automatically brake the appropriate wheel to correct
the problem.
The vehicle is then stabilized by the forces acting on the wheel during
braking. If the vehicle is
oversteering (rear tends to skid out of the
turn), the brakes are mainly applied on the wheel that is on the
outside of the curve. In the case of a vehicle that is
understeering
(tendency to slide out of the curve), the brakes are applied at the rear
wheel that is on the inside of the curve. An acoustic signal indicates
when ESP brake application cuts in =>
&.
The system operates across the entire speed range in combination
with the ABS system=>
page 246. If the Anti-Lock Brake System
(ABS) malfunctions, the ESP will be out of action as well.
Activating
When you turn on the engine, ESP will automatically be activated and
will perform a self-test . As soon as the test is completed, the system
is in normal operating mode.
You can activate a deactivated ESP or deactivated ESP/ ASR if required
by pressing the=>
page 242, fig. 201 button. When they are acti­
vated, the message
ESP/ASR on appears briefly in the display .
Deactivating
The ESP should normally be activated all the time. If necessary , you
can deactivate Anti-Slip Regulation (ASR) or the Electronic Stabiliza­
tion Program (ESP) by pressing the button =>
page 242, fig. 201.
• Deactivating ASR: Tap the but ton . In certain excep tional situa­
tions (e.g. driving with tire chains) , the Anti-Slip Regulation (ASR) can
be deactivated=>
page 244 . The message ASR off appears in the
display as well.
Controls and equip­ ment Safety first Vehicle operation •
Deactivating ESP/ASR
Press the button for more than 3 seconds .
With the ESP/ASR deactivated, the ESP check light comes on, see
=>
page 14. The message ESP switched off appears in the display as
well.
& WARNING
The Electronic Stabilization Program is nevertheless subject to the laws of physics. It is particularly important to pay attention to
this fact on wet and slippery roads. It is therefore important that
you always adapt your driving to the condition of the road and traffic conditions. Do not allow the increased safety provided by
the Electronic Stabilization Program system to lull you into
accepting additional safety risks. •
Electronic differential lock (EDL)
The electronic differential lock monitors the rotational
speed of the drive wheels.
General notes
The electronic differential lock (EDL) helps the car to start moving,
accelerate and climb a gradient on surfaces providing poor or almost
no grip . Without EDL, this would be difficult, if not impossible .
How the system works
The EDL operates automatically . It monitors the rotational speed of
the drive wheels on an axle with the help of the ABS sensors
=>
page 246 . If a noticeable difference in rotational speed between
the drive wheels on one axle is detected (e.g. on slippery ground
on
one side),
the spinning wheel is braked, thereby transferring power to
the othe r drive wheel or wheels (all-wheel drive). This is done up to a
speed of about 60 mph (100 km/h) . Noises from the brake system
signal that wheel spin is being controlled.

Driv ing off
When driving off, always be sure to keep road conditions in mind as
you acce lerate. If one d rive w heel spins because it is on a surface with
less grip, gradua lly inc rease the press ure on the accelerator pedal
un til the car sta rts to move .
Overheating of brakes
To prevent the disc brake of the braked wheel from overheating if
subjected to excessive loads o n this whee l, t he EDL cuts out tem po­
ra rily. The vehicle rema ins operat iona l a nd be haves in the same way
as a ve hicle wit hout EDL.
As soon as the bra ke has coo le d down , ED L swit ches on again au to­
matically.
& WARNING
• When accelerating on slippery surfaces , such as on i ce or snow ,
alway s be careful when depre ssing the accelerator pedal. Even
with the EDL work ing , the drive wheels can spin and reduce your
ability to control your car. Risk of crash!
• The increased safety afforded by EDL does not mean that you
can take safety ri sks . Always adapt your driving style to the road
conditions and traffic situation.
(I) Tips
If a fa ult occurs i n the ABS, the EDL is also not f unct io ni ng . This is
indic ated by t he A BS war ning ligh t=>
page 17.
Anti-Slip Regulation System (ASR)
The Anti- S lip Re gula tio n Sy stem preven ts the dr iven
w heels from spin ning w hen t he car is accelerating .
General notes
The Anti-S lip Reg ulation Sys tem (AS R) is in tegr ate d in the ele ctroni c
stabilization program (ESP) . When the ve hicle starts up and acceler­
at es, the whee ls are p reven ted from sp inning by adjust ing t he engine
power to match the amount of grip avai lable from the road surface.
How the system works
ASR performs automatically, i.e. witho ut the driver 's intervent ion.
W ith the a id of t he ABS sensors=>
page 246, ASR moni to rs the speed
of the dr iven wheels. If the wheels start to spin , th e engine torque is
redu ced a utomatically unti l the t ires find enou gh gr ip to lock onto
the road surface. T he system is active across the entire speed range .
Th e ASR works in conjunction with the ABS. If a malfunction sho uld
occ ur in th e ABS, th e AS R w ill also be out of action.
Activating
The ESP is automatically activated whe n the engine is started and it
performs a se lf-test. You can act ivate a deact ivate d ASR if required by
press ing the=>
pag e 242, fig. 201 button. Whe n it is act ivated, t he
message
ESP/ASR on appears briefly in t he disp lay. Vehicles with
front-wheel d rive a dea ct iva te d ASR a uto mat icall y re-ac tiva tes i tself
at a speed of 40 mp h (70 km/h) .
Deactivating
You can deact ivate t he ASR if required by pressing t he button (for less
t han 3 se conds) =>
page 242, fig . 2 0 1. Wi th the ASR dea ct ivated, the
ESP check light comes on, see=>
page 14. The message ASR off

How the ABS system works
An au tom ati c c heck is m ade w hen a speed of about 4 mp h (6 km /h) is
reac hed. When th is happens, a pump ing no ise can be heard.
If an indivi dual w heel beg ins to rot ate too s low ly in relat ion to vehi cle
speed and tends to lock, t he A BS a utomat ically reduces brake pres­
sure to prevent that w heel from loc king .
Thi s au tom atic adju stm ent pr oces s w ill c au se a
slight vibration of
the brake pedal and some noises to alert you that vehicle speed must
be ad apted to exis tin g road and traff ic c ondi tio ns.
& WARNING
Although the ABS is very effective, always remember that braking
capability is limited by tire traction. Always adjust your driving
speed according to the road and traffic conditions. Do not let the
extra safety afforded by the ABS tempt you into taking extra risks.
The ABS cannot overcome the laws of physics.
[ i J Tips
• If A BS is no t fu nct ion ing prope rly, a w arn ing ligh t will come on .
See
