Instruments and warning/indicator lights
Anti-lock brake system
~ _ (USA models)/ .... (Canada models)
This warning/indicator light monit ors the A BS and the
electronic differenti al lock (EO L).
The ,I<-warning light wi ll come on for a few seconds when the igni ­
tion is switched on. The light will go out after an automatic check
sequence is completed.
There is a malfunction in the ABS when:
• t he war ning/in dicat or li ght does not illuminate when yo u switc h
on the ignition .
• th e warning/indicator l ig ht doe s no t go out after a few sec onds.
• the warning/indicator light illum inates while driving.
Without the electronic assistance of the ABS , the brake system will
still respond and br ake the car. Have the brake system che cked and
restored to its full performance by an authorized Audi dealer a s
soon as possible.
For more information regarding the ABS see
=> page 192 .
Since any malfunction of the ABS also affe cts the ESP, that system's
warning symbol •
=> page 13 will light up along with the A8~/
I':!. (Canada models) warning light.
Unspecific malfunction in the brake system
If bo th the brake warn ing lig ht=> page 15and the wa rn ing l ight
il luminate when the parking brake is released, the likely cause is a
serious m alfun ction in t he brake system beyond an inoperative ABS
=> & .
If an unspec ific defect in the brake sys te m i s indica ted, the e ntire
brake system is likely to be affected and you
must expect degraded
bra ke response and performance.
Since any malfunc tion of the ABS a lso effects the ESP, that system's
warning symbol ~=> page 13 will light up along with the ~1

Aud i dea ler as soon as poss ib le.
& WARNING
• If the / .t (Canada models} warning light does not go out ,
or if it comes on while driving , the ABS system is not working
properly . The veh icle can then be stopped only with the brakes
operating without ABS support . You will not have the protection
ABS provides. Contact your authori zed Audi dealer as soon a s
possible .
• USA models : If both the BRAKE warning light and the
warning light come on at the same time, the rear wheels could
lock up first under hard braking. Rear wheel brake lock -up can
cause loss of veh icle control and an accident . Have your vehicle
repaired immediately by your authorized Audi dealer or a qualified
workshop . Drive slowly and avoid sudden , hard brake application .
• Canada models : If both the brake wa rning light {(j)) and the ABS
warning light come on at the same time , the rear wheels could

Steering
Adjustable steering wheel
The height and reach of the steering wheel can be
adjusted.
First, adjust the driver's seat correctly.
Fig. 107 Lever under
the steering column
-Push the leve r~ fig. 107 down as far as it will go~&.
- Move the steering wheel to the desired positi on.
- Push the leve r back up as fa r as it will go.
There must be at least 10 inches (25 cm) between your chest and the
center of the steering wheel. If you cannot sit more than 10 inches
(25 cm) from the steering wheel, see if adaptive equipment is avail ­
able to help you reach the pedals and increase the distance from the
steering wheel.
Fo r detailed information on how to adjust the driver 's seat, see
=> page
75, "Power seat adjustment".
T he steering wheel can be adjusted even when the ignition is turned
off.
Controls and equip ­
ment
& WARNING
Improper use of steering wheel adjustment and improper seating
position can cause serious personal injury.
• Adjust the steering wheel column only when the vehicle is not
moving to prevent loss of vehicle control.
• Always make sure that the adjustment lever is securely pushed
up so that the position of the steering wheel cannot be changed
unintentionally when the vehicle is moving .
• Adjust the driver's seat or steering wheel so that there is a
minimum of 10 inches (25 cm ) between your breastbone and the
steering wheel=> page 126 , fig. 124 . If you cannot maintain this
minimum distance, the airbag system cannot protect you prop ­
erly .
• If physical limitations prevent you from sitting 10 inches {25
cm ) or more from the steering wheel , check with your authorized
Audi dealer to see if adaptive equipment is available.
• Pointing the steering wheel toward your face decreases the
ability of the supplemental driver's airbag to protect you in an
accident . Always make sure that the steering wheel is pointed
towards your chest.
• Always hold the steering wheel on the outside of the steering
wheel rim with your hands at the 9 o'clock and 3 o'clock positions
to help reduce the risk of personal injury if the driver's airbag
inflates .
• Never hold the steering wheel at the 12 o'clock position or with
your hands at other positions inside the steering wheel rim or on
the steering wheel hub. Holding the steering wheel the wrong way
can cause serious injuries to the hands, arms and head if the
driver's airbag inflates. •

Proper occupant seating positi ·ons
Proper seating position for the driver
The proper driver seating position is important for safe,
relaxed driving.

Fig . 125 Correct head
restraint position for
driver
For your own safety and to reduce the risk of injury in the
event of an accident, we recommend that you adjust the
driver's seat to the following position:
- Adjust the driver's seat so that you can easily push the
pedals all the way to the floor while keeping your knee(s)
slightly bent=:>& . - Adjust the angle of the seatback so that
it is in an upright
position so that your back comes in full contact with it
when you drive.
- Adjust the steering wheel so that there is a distance of at
least 10 inches (25 cm) between the steering wheel and
your breast bone=:> fig. 124. If not possible, see your
authorized Audi dealership about adaptive equipment.
- Adjust the steering wheel so that the steering wheel and
airbag cover points at your chest and not at your face.
- Grasp the top of the steering wheel with your elbow(s)
slightly bent.
- Adjust the head restraint so that the upper edge is as
even with the top of your head as possible but no lower
than eye level and so that it is as close to the back of your
head as possible=:> fig. 125.
- Fasten and wear safety belts correctly=:>
page 139.
- Always keep both feet in the footwell so that you are in
control of the vehicle at all times.
For detailed information on how to adjust the driver's seat, see
=>
page 73, "Adjusting front seats manua lly" or=> page 74,
"Adjusting the power seat".
& WARNING
Drivers who are unbelted, out of position or too close to the airbag
can be seriously injured by an airbag as it unfolds. To help reduce
the risk of serious personal injury:
• Always adjust the driver's seat and the steering wheel so that
there are at least 10 inches (25 cm} between your breastbone and
the steering wheel. .,_

actual vehicle behavior. If the two do not match, for example when
th e vehicle begins to skid, ESP brakes the appropriate wheel auto­
matical ly .
The vehicle is stabilized again by the forces acting on the wheel
during braking. With an oversteering vehicle (tendency for the rear
end to skid out of the curve), the brake application is mainly at the
front wheel on the outside of the curve, with an
understeering
vehicle (tendency to run wide in the curve) at the rear wheel on the
inside of the curve or additionally at the other wheels as needed.
This brake application is accompanied by noises.
ESP works in conjunction with ABS=>
page 192. If there is malfunc ­
tion in the ABS, ESP is also inoperative.
Activating
The ESP is automatica lly activated when the engine is started, and
it performs a self-test. As soon as the test is completed, the system
is in normal operating mode. With ASR deactivated, or with ESP/ASR
deactivated, pressing the button=>
page 188, fig. 158 returns the
system to normal operation.
Deactivating
ESP should normally be activated at all times because this ensures
optimum vehicle stability. Only in certain exceptional cases it does
make sense to deactivate Anti-Slip Regulation (ASR) or the Elec­
tronic Stability Program (ESP) by pressing the button =>
page 188,
fig. 158. Both deactivation stages can only be activated from normal
mode .
Deactivating ASR
Tap the switch. Deactivation is indicated by slow flashing of the ESP
lamp in the instrument cluster. In certain situations (e .g. driving
with snow chains, in deep snow or on loose ground, or when
rocking the car free), it may be necessary to deactivate ASR.
Deactivating ESP/ASR
Press the button for more than 3 seconds. Deactivation is indicated
by the ESP lamp in the ins trument cluster staying on permanently.
Controls and equip­
ment Safety first Vehicle operation
Intelligent technology
This
deactivates the Electronic Stability Program (ESP) in addition to
ASR. No Elec tronic Stability System operation and no Anti -Slip
Regulation is available across the entire speed range; ASR and ESP
are activated only when the brakes are used for the duration of the
braking action and remain active until a stable vehicle condition has
been reached. There is no driving situation which requires ESP to be
deactivated, so this should only be done if the driver's skill and the
traffic situation permit.
& WARNING
• The limits of physics cannot be suspended by ESP. Even in vehi­
cles with ESP. you should always adapt your driving to road and
traffic conditions. This is particularly true on a slippery and wet
road . Do not be tempted by the increased safety provided to take
risks -danger of an accident!
• Please note that when ASR or ESP /ASR is deactivated , the drive
wheels can spin on icy and slippery roads and the vehicle can
break away -danger of skidding!
Electronic differential lock CED1
.)
The electronic differential lock monitors the rotational
speed of the drive wheels.
General notes
The elect ronic differential lock (EDU helps the car to start moving,
accelerate and c limb a gradient on surfaces providing poor or
a lmost no grip. Without EDL, this would be difficult, if not impos ­
s ible.
How the system works
The EDL operates automatical ly. It monitors the rotationa l speed of
the drive wheels on an axle with the help of the ABS sensors
=>
page 192. 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
Vehicle care Do-it-yourself service Technical data

How the ABS system works
An aut omatic check is made whe n a speed of ab out 4 mph (6 km/h)
is reached. When this happens, a pumping noise can be heard.
I f an individua l wheel begins to rotate too slowly in relation to
ve hicle speed and ten ds to lock, the A BS automatical ly reduces
brake pressure to prevent that wheel from locking.
T his auto matic adjust ment p rocess wil l cause a
slight vibration o f
the brake peda l and some noises to alert you that veh ic le speed
must be ada pted to e xisting roa d and traff ic c onditions.
& WARNING
Although the ABS is very effective , always remember that braking
c apability is limited by tire tra ction . 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 e xtra risks .
The ABS cannot overcome the laws of physics.
[ i ) Tips
• I f ABS is not functioning properly, a warning light wil l come on.
See
=> page 16.
• I f a fau lt occurs in the ABS, the E DL is als o not fu ncti onin g. This
is indicated by the ABS warning light. •
Brake assistant
The brake a ssi st ant is de sig ned to a chieve th e opti mum
b ra kin g eff ec t.
The brake assistant helps to increase the effective braking power
and thus to ac hieve a s horte r stop ping dis tance. If the drive r
presses the brake pedal very quick ly, the brake assistant automati ­
ca lly b oosts the braki ng force to the maximu m level, up to th e point
where the anti -loc k brake function (A BS) intervenes to stop the
whee ls from loc king. You should then keep the brake pedal pressed

until
the vehicle has braked to the required speed . The brake assis ­
t an t swi tc h es itse lf o ff as s oon as you r eleas e the b rake pe dal.
The brake assistant wi ll not be operative if there is a malfunction in
the ABS .
& WARNING
Please remember that the accident risk always increases if you
drive too fast , espe cially in corners or on a slippery road , or if you
follow the vehicle ahead of you too closely . An increased accident
risk cannot be compensated even by the brake assistant , so
always maintain a safe speed. •
ciectro-mechanical power assist
Th e e le ctr o-me ch anic al pow er assis t helps the driv e r

The degree of powe r ass ist is electronically matched to veh icle
