• 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 rearward-facing child safety seat in a
rear seating position and have the airbag system inspected by
your authorized 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
activate the convertible locking retractor:
- 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.
- Gu ide the safety belt back into the retractor until the belt
lies flat and snug on the child safety seat.
Controls and equip­
ment Safety first Vehicle operation
- You should
hear a "clicking" noise as the belt winds back
into the inertia reel. Test the convertible locking retractor
by pul ling 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 (2.5 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.
• Always buckle the child safety 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 crash.
• Always make sure the seat backrest to which the child restraint
is installed is in an upright position and securely latched into place
and cannot fold forward. Otherwise, the seat back with the child
safety seat attached to it could fly forward in the event of an acci­
dent or other emergency situation.
• Always read and heed all WARNINGS whenever using a child
restrained in a vehicle is being used=>

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.

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

& 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. •

How the ABS system works
An au tomatic check is made when a speed of about 12 mph (20
km/h) is reached. When this happens, a pumping no ise can be
heard .
I f an individua l wheel begins to ro tate too s low ly in relation to
vehic le speed and tends to lock, the ABS automatical ly reduces
b rake pressure t o preven t tha t whee l from locking.
This automatic adjustment process wil l cause a

Although the ABS is very effe ctive , always remember that braking
c apability is limited by tire traction. Always adjust your driving
speed a ccording to the road and traffi c conditions. Do not let the
extra safety afforded by the ABS tempt you into taking extra risks.

Energy management
Starting ability is optimized
Energy management controls the distribution of electrical
energy and thus optimizes the availability of electrical
energy for starting the engine .
If a vehicle with a conventional energy system is not driven for a
long period of time , the battery is discharged by idling current
consumers (e.g . immobilizer) . In certain circumstances it can result
in there being insufficient energy available to start the engine.
Intelligent energy management in your vehicle handles the distribu ­
tion of electrical energy. Starting ability is markedly improved and
the life of the battery is extended.
Basically, energy management consists of
battery diagnosis, idling
current management
and dynamic energy management .
Battery diagnosis
Battery diagnosis continuously determines the state of the battery.
Sensors determine battery voltage, battery current and battery
temperature. This determines the current state of charge and the
power of the battery.
Idling current management
Idling current management reduces energy consumption while the
vehicle is standing . With the ignition switched off, it controls the
energy supply to the various electrical components. Data from
battery diagnosis is considered.
Controls and equip­ ment Safety first Vehicle operation
Intelligent technology
Depending
on the battery's state of charge, individual consumers
are gradually turned off to prevent excessive discharge of the
battery and thus maintain starting capability.
Dynamic energy management
While the vehicle is being driven, dynamic energy management
distributes the energy generated according to the needs of the indi­
vidual components. It regulates consumption, so that more elec­
trical energy is not being used than is being generated and ensures
an optimal state of charge for the battery.
[ i] Tips
• But even energy management cannot negate the limits of
physics. Consider that the power and life of a battery are limited.
• If starting ability is threatened, you are informed by a warning
~ page 242, "Driver notification in the instrument cluster
display". •
What you should know
The highest priority is given to maintaining starting capa­
bility.
The battery is severely taxed in short-distance driving, in city traffic
and during the cold time of year. Abundant electrical energy is
required, but only a little is generated. It is also critical if the engine
is not running and electrical components are turned on. In this
instance energy is being consumed but none is being generated.
It is in precisely these situations that you will notice energy manage ­
ment actively regulating the distribution of energy.
Vehicle stands for an extended period
If you do not drive your vehicle over a period of several days or
weeks, electrical components are gradually cut back or switched off.
This reduces energy consumption and maintains starting capability
over a longer period.

Driving and environment
The first 1,000 miles (1,500 km) and afterwards
!\Jew engine
The engine needs to be run-in during the first 1,000 miles
(1,500 km).
F o r th e fir st 600 mil es (1,000 kilomet ers):
Do not use full throttle.
- Do not drive faster than 3/4 of the top speed marked on
the speedometer.
- Avoid high engine speeds .
From 600 t o 1,000 mil es (1,000 t o 1,500
kil om eter s):
- Speeds can gradually be increased to t he maximum
permiss ible road or engine speed .
During and aft er br eak-in p eri od
- Do not rev the engine up to high speeds when it is cold. This applies whether the transm ission is in N (Neutral) or
1n gear.
Aft er the br eak-in p eriod
- D o not exceed max imum e ngine speed unde r any
circumstances.
- Upshift into the next higher gear before reaching the red
area at the end of the tachome ter scale
~ page 8 .
Controls and equip­
ment Safety first Vehicle operation
Dri
ving and environm ent
During the first few hours of driving, the eng ine's internal friction is
higher than later when all the moving parts have been broken in.
How well this break -in process is done depends to a considerable
extent on the way the vehicle is driven during the first 1,000 miles
(1,500 ki lometers).
0 Not e
Extreme ly high engine speeds are automatically reduced. However,
these rpm limits are programmed for an engine well run-in, not a
new engine .
~ For the sake of the environment
Do not drive with unnecessarily high engine speeds -upshifting
early saves fuel, reduces noise and protects the environment .
New tires
If your v ehic le is running on new tires, drive very careful ly
for the first 350 mi les (500 k ilometers) after fitt ing .
