Steering
Adjusting the steering wheel column
The height and reach of the steering wheel can be
adjusted.
Fig . 142 Lever under
the steering column
First, adjust the driver's seat correctly.
- Push the
lever => fig. 142 -Arrow- =>& .
Move the steering wheel to the desired position.
- Push the lever against the steering column unt il it locks.
There must be at least 10 inches (25 cm) between your breastbone
and the center of the steering wheel. If you cannot sit more than 10
inches (25 cm) from the steering wheel,
we recommend that you
investigate whether adaptive equipment is available to help you
reach the pedals and increase your seating distance from the
steering wheel. For detailed information on how to adjust the driver's seat, see
=> page 97, "Power seat adjustment"
.
& 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 168, fig. 162. If you cannot maintain this
minimum distance the airbag system cannot protect you properly.
• 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.

Power steering
Power steering makes it easier to steer the vehicle when
the engine is running.
If the engine is not running the power steering does not work and
you will find it more difficult to turn the steering wheel.
Whenever the steering wheel is turned all the way to the left or right
a lo t of stress is placed on the power steering pu mp. When this
happens you will hear a noise coming from the power steering
pump .
0 Note
Never hold the steering wheel turned all the way to the left or right
longer than 15 seconds when the en gine is running -damage to
the power steering system is likely! •

the steering wheel in either direction un til you hear it lock in to
place. You shou ld always lock the steering whenever you leave your
vehicle. This makes a vehicle theft even more
difficult =>& .
Ign iti on on @
If it is d iff icult to turn the key after you have inserte d it into the igni ­
tion lock, turn the steering whee l back and forth . This will take the
load off the s teering lock mechanism and you will be able to turn the
key free ly and start the engine.

temporarily interrupted to conserve battery power. After the engine
has started, release the key and it will return to position
0-
Before the starter can be operated again the key must be turned
back to position
G) . The non-repeat lock prevents you from
damaging the starter when the engine is running.
_& WARNING
• Never remove the key from the ignition lock while the vehicle is
moving. The steering wheel will lock causing loss of control.
• If you have to leave your vehicle-even for just a minute- always
remove the ignition key and take it with you. This is especially
important if you are going to leave children behind in the vehicle.
The children could start the engine or use other vehicle controls.
Unsupervised use of vehicle controls (for example, power
windows) can cause serious personal injuries.
[ i] Tips
If the vehicle battery has been disconnected and then reconnected,
then you must leave the key in position
0 for about 5 seconds
before you can start the engine. •
Ignition key safety lock
The ignition key can only be removed when the selector
lever is in the
"P" (Park) position.
After switching off the ignition, the ignition key can only be
removed from the ignition lock when the selector lever is in the
"P"
(Park) position. After you have removed the key, the selector lever is
locked and cannot be moved. •
Starting and stopping the engine
Starting the engine
The engine can only be started with your original Audi
key.
-Set the parking brake.
-Move the selector lever to the neutral position (automatic
transmission: selector lever in P or N)
=> & .
-On vehicles with manual transmission, fully depress the
clutch pedal.
-Turn the ignition key to position 0 => page 135, fig. 143
- do not depress the gas pedal when starting the engine!
-Let go of the key as soon as the engine starts.
A cold engine may at first be loud after it has been started. This is
due to the hydraulic valves building up the oil pressure . This is
normal and no need for concern.
If the engine does not start immediately, stop trying after 10
seconds and then try to restart the engine about 30 seconds later.
What to do if the engine does not start
• ~ page 330
• ~ page 332, "Emergency towing with commercial tow truck"
_& WARNING
Never start or let the engine run in a confined or enclosed area.
Exhaust fumes from the engine contain carbon monoxide, a color­
less and odorless gas. Carbon monoxide can be fatal if inhaled.
• Never leave the engine idling unattended. An unattended
vehicle with a running engine poses a danger of personal injury or
theft.

Cruise control
General information
The cruise control system allows you to maintain a
constant speed.
The cruise control system allows you to maintain and constant
driving speed when driving faster than 18 mph (30 km/h) -to the
extent this is possible with the given engine power and braking
characteristics. This allow you to take your foot off the "gas" and
rest it, especially on long trips .
The indicator light CRUISE (USA)/
•l'l (CDNl in the instrument cluster
illuminates when the system is on .
& WARNING
• To help keep the vehicle under control, do not use the cruise
control system when driving on winding or slippery roads (as
caused by heavy rain or loose gravel on the road surface), or in
heavy or varying traffic.
• Only use the cruise control when traffic, road and weather
co nd itions allow you to drive at a steady speed.
[ i] Tips
The cruise control cannot maintain a constant speed when driving
downhill. The vehicle will accelerate under its own weight. Down­
shift to a lower gear or use the brakes to slow down .•
Storing a speed
You must set and then store a vehicle speed using the
cruise control.
Fig. 145 Cruise control
switches
- Accelerate until you reach the driving speed you want to
store.
- Pull
lever © towards the steering wheel G) => fig. 145 to
switch the system on.
- Press button
@.
After you release button @, the current vehicle speed is stored and
maintained .•
Changing a stored speed
You can change a stored speed.
Accelerate (faster)
-Lift lever © toward 0 => fig. 145 .
- Release the lever to store the new speed.

&, WARNING (continued )
• Before des cending a steep grade , reduce speed and shift trans­
mi ssion into a lo wer gear or lower driving po sition . Do not ride the
brake s or hold the pedal down too long or too often . This could
cau se the brake s to get hot and dimini sh braking efficiency .
• Do not ride the brakes by resting your foot on the ped al when
you do not intend to brake. This may cause the brakes to overheat, premature wear and in creased stopping distan ce.
• Under certain climati c and operating conditions such a s
passing through water, driving in heavy rain or after washing the
v ehicle , the effectiveness of the brakes can be reduced . In winter ,
ice can a ccumulate on the brake pads , linings , discs and drums .
Cautiously apply brakes for a te st. Brakes will dry and ice coating s
will be cleaned off after a few cautious brake applicat ions .
• Driving for an extended period of time on salt-co vered roads
without using your brakes can also affect braking effi ciency . Clean
off accumulated salt coating from brake discs and pads with a few
c autious brake appli cations .
• If you damage the front spoiler , or if you install a different
spoiler , be sure the air flow to the front brakes is not obstructed .
Otherwise the brake system could overheat reducing the effective ­
ness of the entire brake system .
• Failure of one brake circuit will impair the braking capability
resulting in an increased stopping distance . Avo id driving the
vehicle and have it towed to the nearest Audi dealer or qualified
workshop .•
Brake booster
T he brake booster add s ex tra braking power.
The bra ke booster works wit h vacuum pressure which is created
only whe n th e e ng in e is
runn ing=> &,.
& WARNING
• Never let the vehi cle roll to a stop with the engine shut off .
• If the brake booster is not working , for example when towing
your vehicle , or because the brake booster has somehow been
damaged, the brake pedal must be pre ssed considerably harder to
make up for the lack of booster assistance . •
Functioning of Anti-Lock Brake System (ABS)
A BS preven ts th e wh eels fr om lock ing up und er b rak ing.
T he ABS contributes effectively to vehicle contro l since it prevents
th e w heels from
lo cki ng w he n t he brakes a re a ppli ed. T h is mea ns
that the vehicle remains steerable and is less likely to skid.
With ABS you do not need to pump the brake . Just hold the brake
pedal down .
However, do not expect that the ABS shortens braking distance
u nder all circum sta nces. Whe n driving o n gravel or on newly fa lle n
snow on top of icy surfaces, braking distance may be even longer,
t herefore, under these ci rcums tances, it is espec ial ly i mpo rtant th at
you driv e slowly and with great care.
How the ABS system works
An automatic check is made when a speed of about 4 mph (6 km/h)
i s r eac hed . Wh en th is happe ns, a pumpi ng noi se can be hea rd.
I f a n indiv idual wheel be gins to rotat e too slowly i n relation to
vehic le speed and tends to lock, the ABS automatical ly reduces
brake pressur e to prevent tha t whee l from loc king .
Th is a utomatic adjustment process wi ll cause a
slight vibration of
t he brake peda l a nd s om e noi ses t o a lert y ou th at ve hicle spee d
must be adapted to existing road and traffic conditions. _..
