overview: installation
of the seat using the
vehicle's safety belt
system
- When using the vehicle safety belt to install a child safety
seat, you must first activate the convertible locking
feature on the safety belt to prevent the child safety seat
from moving ==>
page 223 or install the seat using the
LATCH attachments
- Push the child safety seat down with your full weight to
get the safety belt really tight so that the seat cannot
move forward or sideways more than one inch (2.5 cm)
==> page 223.
If the child safety seat is equipped with a tether strap,
attach it to the tether anchors==>
page 230.
A toddler or child is usually too large for an infant restraint if it is
more than one year old and weighs more than 20 lbs. (9 kg) .
Toddlers and children who are older than one year up to about 4
years old and weigh more than 20 lbs. (9 kg) up to 40 lbs . (18 kg)
must always be properly restrained in a child safety seat certified for
their size and weight~
page 219, fig. 205 and~ page 220, fig. 206.
The airbag on the passenger side makes the front seat a potentially
dangerous place for a child to ride. The front seat is not the safest
place for a child in a forward-facing child safety seat . It is a very
dangerous place for an infant or a larger child in a rearward -facing
seat.
& WARNING
Not using a child safety seat, using the wrong child safety seat or
improperly installing a child restraint increases the risk of serious
personal injury and death in a collision or other emergency situa­
tion.
• Children on the front seat of any car, even with Advanced
Airbags, can be seriously injured or even killed when an airbag
inflates. 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 install rearward-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 circumstances and
the PASSENGER AIR BAG OFF light does not come on and stay on,
immediately install the rearward-facing child safety seat in a rear
seating position and have the airbag system inspected by your
authorized Audi dealer .
• Always read and heed all WARNINGS whenever using a child
restrained in a vehicle is being used~
page 179, "Safety belts",
~ page 188, "Airbag system" and~ page 213, "Important things
to know".
& WARNING
If exceptional circumstances require the use of a forward-facing
child restraint on the front passenger's seat, the child's safety and
well-being require that the following special precautions be taken:
• Make sure the forward-facing seat has been designed and certi­
fied by its manufacturer for use on a front seat with a passenger
front and side airbag.
~

& WARNING !continued)
• Always follow the manufacturer's instructions provided with
the child safety seat or infant carrier.
• Always move the front passenger seat into the rearmost posi­
tion of the passenger seat's fore and aft adjustment range, and as
far away from the airbag as possible before installing the child
restraint.
• Always make sure that nothing prevents the front passenger's
seat from being moved to the rearmost position in its fore and aft
adjustment range .
• Always make sure the backrest is in 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.
• If the light does not stay on, perform the checks~
page 199,
uMonitoring 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. •

Child Safety
Booster seats and safety be lts
Properly used booster seats can help protect children
weighing between about 40 lbs. and 80 lbs. (18 kg and
36 kg) who are less than 4
ft. 9 in. (57 inches/1.45 meters)
tall.
Fig . 207 Rear seat :
child properly
restrained in a booster
seat
The vehicle 's safety belts alone will not fit most children
until they are at least 4 ft. 9 in. (57 inches/1.45 meters) 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.
- Always position the shoulder portion of the safety belt midway over the child's shoulder. If you must transport
an older child in a booster seat on the front passenger
seat , you can use the safety belt height adjustment to
help adjust the shoulder portion properly.
- Always make sure that the shoulder portion of the safety
belt never rests against or across the child's neck.

The system operates across the entire speed range in combination
with the ABS system. If the Anti -Lock Brake System (ABS) ma lfunc­
tions, the ESP wil l also shut down .
How the system works
The Anti -Lock Brake System (ABS), Electronic Differential Lock (EDU
and the Anti -Slip Regulation System (ASR) are integrated in the elec­
tronic stabilization program. In addition to the data provided by
th ese functions, the ESP control unit requires additional measure ­
ment data provided by high performance sensors . The rotational
speed of the vehicle about its vertica l axis, vehicle acceleration in
the 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 continua lly
compared with the actual behavior of the vehicle. If the two do not
match, for example, when the vehicle starts hydrop laning on a wet
road, ESP will automatically brake the appropriate whee l to correct
the prob lem.
The vehicle is then stabi lized by the forces acting on the whee l
during braking. If the vehicle is
oversteering (the vehicle turns too
sharply and the rear wheels slide toward th e ou tside of a curve), the
brakes are main ly app lied on the wheel that is on the outside of the
curve . In the case of a vehicle that is
understeering (the vehicle does
not turn sharply enough and pushes out of a curve), the brakes are
applied as needed on the wheel that is on the inside of the curve or
additional ly on the other wheels. An acoustic signal indicates when
ESP brake app lication cuts in=>&.
T he system operates across the entire speed range in combination
with the ABS system =>
page 238. 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 automatica lly be activated
and will perform a se lf-test. As soon as the test is comp leted, the
system is in norma l operating mode.
Controls and equip­
ment Safety first Vehicle operation
Intelligent technology
You
can activate a deactivated ESP or deactivated ESP/ASR if
required by pressing the::::>
page 234, fig. 215 ::::> page 234, fig. 214
button . When they are activated, the message
ESP /ASR on appears
briefly in the display .
Deactivating
The ESP should normally be activated al l the time. If necessary, you
can deactivate Anti -Slip Regu lation (ASR) or the Electronic Stabiliza­
tion Program (ESP) by pressing the button=>
page 234, fig. 215.
• Deactivating ASR: Tap the button . In certain exceptional situa­
tions (e .g. driving with tire chains), the Anti-Slip Regulation (ASR)
can be deactivated =>

& 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 Elec­
tronic 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 (EDU helps the car to start moving,
acc elerate and c limb a gradient on surfaces providing poor or

almost no grip. Without EDL, this would be difficult, if not impos­
sible.
How the system works
The EDL operates automatically. It monitors the rotational speed of
wheels with the help of the ABS sensors=:,
page 238 . If a noticeable
slip is detected at the wheels (e.g. on slippery ground on one side),
the spinning wheels are braked and power is transferred to the
other wheels. 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.
Driving off
When driving off, always be sure to keep road conditions in mind as
you accelerate. If one drive wheel spins because it is on a surface
with less grip, apply
plenty of throttle until the car starts to move.
Overheating of brakes
To prevent the disc brake of the braked wheel from overheating if
subjected to excessive loads on this wheel, the EDL cuts out tempo­ rarily. The vehicle remains operational and behaves in the same way
as a vehicle without EDL.
As soon as the brake has cooled down, EDL switches on again auto ­
matically.
& WARNING
• When accelerating on slippery surfaces, such as on ice or snow,
always be careful when depressing the accelerator pedal. Even
with the EDL working, 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 risks. Always adapt your driving style to the road
conditions and traffic situation.
[ i] Tips
If a fault occurs in the ABS, the EDL is also not functioning . This is
indicated by the ABS warning light=:,
page 15. •
Anti-Slip Regulation System (ASR)
The Anti-Slip Regulation System prevents the driven
wheels from spinning when the car is accelerating.
General notes
The Anti-Slip Regulation System (ASR) is integrated in the electronic
stabilization program (ESP) . When the vehicle starts up and acceler ­
ates, the wheels are prevented from spinning by adjusting the
engine power to match the amount of grip available from the road
surface.
How the system works
ASR performs automatically , i.e. without the driver's intervention .
With the aid of the ABS sensors=:,
page 238, ASR monitors the
speed of the driven wheels. If the wheels start to spin, engine torque
is reduced automatically until the tires find enough grip to lock onto
the road surface. The system is active across the entire speed range.
The ASR works in conjunction with the ABS. If a malfunction should
occur in the ABS, the ASR will also be out of action.
Activating
The ESP is automatically activated when the engine is started and it
performs a self-test . You can activate a deactivated ASR if required
by pressing the=:,
page 234, fig. 215 button. When it is activated,
the message
ESP/ASR on appears briefly in the display.
