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 194 .
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

& 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

Ignition on G)
If it is difficult to turn the key af ter you have inserted i t into the igni­
tion lock, turn the steering wheel back and forth . This will take the
load off the steering lock mechanism and you wil l be able to turn the
key freely and start the engine .
Starting the engine @
In this position the engine starts . Whi le the engine is starting, the
power supply to the headlights and o ther elec trical consumers is
temporari ly interrupted to conserve battery power . After the engine
has started, release the key and it will return to position
G).
Before the starter can be operated again the key must be turned
back to posi tion

Proper occupant seating positi ·ons
Proper seating position for the driver
The proper driver seating position is important for safe,
relaxed driving.
Fig . 128 The correct
distance between
driver and steering
wheel
Fig . 129 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. 128. 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. 129.
- Fasten and wear safety belts correctly=:>
page 141.
- 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 75, "Adjusting front seats manua lly" or=> page 76,
"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. .,_

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

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

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 problem checked and set right by an authorized Audi
dealer as soon as possible.
• If a steering malfunction occurs, this is signaled with the or.
@ indicator lights and a warning tone, see.
[ i) Tips
• If the power steering system should fail, or if the engine is not
running (for example, while being towed), you will still be able to
steer the vehicle. However, more effort will be required to do so.
• If the power steering system is not functioning properly, contact
your authorized Audi dealer immediately.
Applies to vehicles: with All Wheel Drive
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 191, "Electronic differ­
ential lock (EDU".
Winter tires
When driving in the winter, your vehicle with All Wheel Drive has an
advantage, even with regular tires. In winter road conditions it may
be advisable to mount winter tires (or all -season tires) for improved
driveability and braking: these tires must be mounted on
all four
wheels.
See also ::::, page 260, "Winter ti res".
Snow chains
Where snow chains are mandatory on certain roads, this normally
also applies to vehicles with all-wheel drive:::::,
page 261, "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 255, "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 199.
& WARNING
Always adjust your driving to road and traffic conditions. Do not
let the extra safety afforded by the all-wheel drive tempt you into
taking extra risks.
• Although the quattro ®all-wheel drive is very effective, always
remember that braking capacity is limited by tire traction. You
should therefore not drive at excessive speeds on icy or slippery
road surfaces.
• On wet road surfaces, be careful not to drive too fast because
the front wheels could begin to slide on top of the water (hydro­ planing). If this should occur, you will have no warning from a
sudden increase in engine speed as with a front-wheel drive
vehicle. Always drive at speeds which are adjusted to the road
conditions -risk of crash!
n

-~_T_ ir_e_ s_ a_ n_d _ w_ h_ e_e _l_s _________________________________________________ _
& WARNING (continued)
crashes and serious personal injuries . Have worn or damaged tires
replaced immediately.
• Tires age even if they are not being used and can fail suddenly,
especially at high speeds. Tires that are more than 6 years old can
only be used in an emergency and then with special care and at
low speed.
Glossary of tire and loading terminology
Accessory weight
means the combined weight (in excess of those standard items
which may be replaced) of automatic transmission, power steering,
power brakes, power windows, power seats, radio, and heater, to
the extent that these items are available as factory-installed equip­
ment (whether installed or not).
Aspect ratio means the ratio of the height to the width of the tire in percent.
Numb ers of 55 or lower indicate a low sidewall for improved
steering response and better overall handling on dry pavement.
Bead
means the part of the tire that is made of steel wires, wrapped or reinforced by ply cords and that is shaped to fit the rim.
Bead separation means a breakdown of the bond between components in the bead.
Cord
means the strands forming the plies in the tire.
& WARNING (continued)
• Never mount used tires on your vehicle if you are not sure of
their "previous history." Old used tires may have been damaged
even though the damage cannot be seen that can lead to sudden
tire failure and loss of vehicle control.
• If you notice unusual vibration or if the vehicle pulls to one side
when driving, always stop as soon as it is safe to do so and check
the wheels and tires for damage . •
Cold tire inflation pressure
means the tire pressure recommended by the vehicle manufacturer
for a tire of a designated size that has not been driven for more than
a couple of miles (kilometers) at low speeds in the three hour period
before the tire pressure is measured or adjusted .
Curb weight means the weight of a motor vehicle with standard equipment
including the maximum capacity of fuel, oil, and coolant, air condi­
tioning and additional weight of optional equipment.
Extra load tire
means a tire designed to operate at higher loads and at higher infla ­
tion pressures than the corresponding standard tire . Extra load tires
my be identified as "XL",
"xi", "EXTRA LOAD", or "RF" on the side ­
wall.
Gross Axle Weight Rating ("GAWR")
means the load-carrying capacity of a single axle system, measured
at the tire -ground interfaces .
Gross Vehicle Weight Rating ("GVWR"l
means the maximum total loaded weight of the vehicle.
