& WARNING
• Never remove the key from the ignition lock while the vehicle
is moving. The steering wheel will lock , cau sing loss of control.
• If you ha ve to leave your vehicle, even for ju st a minute, alw ays
remove the ignition key and take it with you. This i s especially
important if you are going to leave children unattended in the
vehicle. The children could start the engine or use other vehicle c ontrols . Unsupervised us e of vehicle controls (for example, power
windows) can cause serious personal inju ries.
0 Note
• If the ~ symbol in the display blinks, there is a malfunction in the
electronic stee ring column lock. Follow the instr uctions in
~ page 28, "Steering malfu nction i" .
• If the ~ symbol in the display blinks, there is a malfunction in the
electronic ignition lock . Follow the instr uctions in~

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.

these circ umstances, it is especially importa nt that you dr ive slowly
a nd wi th grea t ca re .
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
~ page 17 .
• If a f ault o ccur s in the A BS, the EDL is also not func tio ning. T his is
ind icated by the ABS war ning light.

as soon as you re lease the brake pedal.
The brake assistant will not be operative i f th ere is a ma lf u nction in

& WARNING
Please remember that the accident risk always increases if you
drive too fast, especially in corners or on a slippery road , or if you
follow the vehicle ahead of you too clo sely. Increa sed risk of an
accident cannot be compensated for even by the brake assistant ,
so always maintain a safe speed .•

steering support force that is no longer proportionate to the vehicle
speed. This is most noticeable when turning the steering wheel at low
speeds (for example when parking), - more effort will be required
than usual.
• Be aware of the different than usual steering response and adjust
your steering force accordingly.
• Have the prob lem checked and set right by an Audi dealer as soon
as possible.
[ i ] Tips
• When the engine is running, never hold the steering wheel turned
all the way to the right or to the left for longer than 15 seconds . The
power steering pump will overheat the hydraul ic fluid if you keep
holding the steering wheel turned all the way . This is likely to damage
the power steering system.
• If the power steering system should fail entirely, or if the engine
is not running (for examp le, while be ing towed), you will still be able
to steer the vehicle. However,
considerably more effort will be
required to do so.
• If the power steering system should have a leak, or is not func­
tioning properly, contact your authorized Audi dealer immediately.
• The power steering system requires a specially formulated
hydra ulic fluid. The power steering reservoir is the one located most
forward on the left side of the engine compartment=>
page 280. The
correct fluid level in the reservoir is important for proper functioning
of the power steering . •
A pp lies to veh icles: with All W heel Dr ive
Driving with your quattro®
With All Wheel Drive, all four wheels are driven.
General information
With All Wheel Drive, power is distributed to all four wheels . This
happens automatically depending on your driving style and the road
conditions at the time . See also=:>
page 243, "Electronic different ial
lock ( EDL)".
Winter tires
When driving in the winter, your vehicle with A ll Wheel Drive has an
advantage , even w ith regular t ires . In winter road condit ions it may
be advisable to mount winter tires (or all-season tires) fo r improved
dr iveability and braking: these tires must be mounted on
all four
wheels.
See also =:> page 311, "Winter tires".
Tire chains
Where tire chains are mandatory on certain roads, this normally also
applies to vehicles with A ll Whee l Drive=:>
page 312, "Snow chains".
Replacing wheels/tires
Vehicles with All Wheel Drive must always have tires of the same size .
Also avoid tires with different tread depths . For details see page
=:>
page 307, "New tires and replacing tires and wheels ".
Off-Road driving?
Your Audi does not have enough ground clearance to be used as an
off-road vehicle . It is therefore best to avoid rough tracks and uneven
terrain as much as possible. Also refer to=>
page 252.
& WARNING
Always adjust your driving to road and traffic conditions. Do not
let the extra safety afforded by All Wheel Drive tempt you into
taking extra risks.
