you leave your vehicle. This makes a vehicle
theft even more difficult ¢ .&. .
Ign ition key safety lock
Afte r switch ing off the ignition, the ig nit ion
key ca n only be removed from the ig nition
l ock when the se lector lever is in the "P"
(Park) position . After you have removed the
key, the selector lever is locked and cannot be
moved.
Ign ition on (D
If it is diffic ult to turn the key afte r you have
inse rted it into the ignition lock, turn the
steering whee l back and forth. This will take
the load
off the steering lock mechanism and
you will be able to turn the key freely and start the engine.
Starting th e engine @
In this position the engine starts . While the
engine is starting, the power supply to the headlights and other e lectrica l consumers is
temporari ly interrupted to conserve battery
power. After the engine has started, release
the key and it will return to posit io n
(D .
Before the starter can be operated again the
key must be turned back to position @. The
non-repeat lock prevents you from damaging
the starter when the engine is runn ing .
A WARNING
-Never remove the key from the ign ition
lock whi le the vehicle is mov ing . The
steering wheel will lock causing loss of
co ntrol.
- If you have to leave your veh icle - even
for just a m inute - a lways remove t he ig­
ni tion key and take it with you. This is es­
pecially important if you are going to
leave ch ildren behind in the vehicle. The
children co uld start the engine or use
other vehicle controls. Unsupervised use
of vehicle controls (for example, power
windows) can cause serious personal in­
jur ies .

(D Tips
If the vehicle battery has been disconnect­
ed and then reconnected, then yo u must
l eave the key in posit ion
(D for about 5
seconds before you can start the engine.
Starting and stopping
the engine
' Starting the engine
The engine can only be started with an origi­
nal Audi key .
.,. Se t the par king brake.
.,. Move the selector lever in P or
N q .&_ .
.,. Turn the ignition key to position @
~ page 72, fig. Bl -do not depress the gas
peda l 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 bu ild ing up the oil pressure. Th is nor­
mal 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.
A WARNING
-Never start or let the eng ine run in a con-
fined o r enclosed area . Exhaust fumes
from the engine co ntain carbon monoxide,
a colorless and odo rless gas. Ca rbon mon ­
oxide can be f atal if inhaled.
- Never leave the engine id ling unattend­
ed. An una ttended veh icle w ith a runn ing
engine poses a danger o f personal injury
or theft .
(D Note
-Avo id high engine speeds, fast accelera ­
tion or heavy engine loads while the en­
gine is still cold. This could damage the
engine.
- The e ngine cannot be started by pushing
or towing the vehicle . .,..

7 4 On the road
@ For the sake of the environment
To avoid unnecessary engine wear and to reduce exhaust emissions, do not let your
veh icle stand and warm up. Be ready to
drive off immediately after start ing your
veh icle. Maintain moderate speed until the
engine is comp letely warm. Remember,
the engine performs best at operating
temperature.
Stopping the engine
• Turn the ign ition key to position@
~ page 72, fig. 81.
&_ WARNING
-Never turn off the engine before the ve­
hicle has come to a complete stop. The
full function of the brake booster and the
power steering is not guaranteed. You
must use more force to turn or brake if
necessary. Because you cannot steer and
brake as you usually would, this could
lead to crashes and serious injuries.
- The radiator fan can continue to run for
up to 10 minutes even after you have
turned off the engine and removed the
ignition key . The radiator fan can also
turn on again if the engine coolant heats up because of intense sunlight or heat
build-up in the engine compartment.
(D Note
Do not stop the engine immediate ly after
hard or extended driving. Keep the engine
running for approximately two minutes to
prevent excessive heat build-up.
Parking brake
Parking brake
When the parking brake is set, it prevents the
vehicle from rolling away unintentionally.
Fi g. 82 Center console: Park ing brake set
Setting the parking brake
• Pull the pa rking brake lever all the way up.
Releasing the parking brake
• Pull the parking brake lever up slightly and
press the release button at the same time
~fig. 82 -arrow-.
• Keep the release button pressed and lower
the parking brake~.&,.
If you should drive off with the parking brake
still set, a warning tone will sound and the
fol low ing will appear in the instrument clus­
ter to remind you to release the parking
brake:
Parking brake set
The parking brake warning comes on only af­
ter you have driven for longer than 3 seconds
and faster than 3 mph (5 km/h).
The parking brake warning light . (USA)/ .
(CON) illuminates when the parking brake is
set and you switch on the ignition.
&_ WARNING
Always release the park ing brake com-
pletely. A partially engaged brake will
overheat the rear brakes, reduce their ef­
fectiveness and cause excessive wear. This
could lead to brake failure and an accident. .,..

Intelligent technology Notice about data
recorded by vehicle
control modules
Your vehicle is not equipped with an Event Da­
ta Recorder (EDR), installed by some manu­
facturers for the express purpose of capturing
data for retrieval after an accident or crash
event. EDR's are sometimes called "crash re­
corders".
Some state laws restrict the retr ieval or down­
loading of data stored by EDR's that were in­
stalled in a vehicle for the express purpose of
retrieving data after an accident or crash
event without the owner's consent.
Although your vehicle is not equipped with an
EDR, it is equipped with a number of electron­
ic control modules for various vehicle systems
such as, for examp le, engine function, emis­
sion control, as well as for the airbags and
safety belts.
These electronic control modules also record
vehicle-related data during norma l vehicle op­
eration for diagnostic and repair purposes.
The recording capacity of the electronic con­
trol modules is limited to data (no sound is re­
corded) and only a small amount of data is ac­
tually recorded over a very limited period of
time and stored when a system fault or other
condition is sensed by a control unit. Some of
the data then stored may relate to vehicle
speed, direction, braking as we ll as restraint
system use and performance in the event of a
crash or other condition. Stored data can only be read and downloaded with special equip­
ment.
Electronic Stabilization
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of
skidding and loss of veh icle control. It works
only when the engine is running. ESC detects
Intelligent technology 141
certain difficult driving situations, including
when the vehicle is beginning to spin (yaw)
out of control and helps you to get the veh icle
back under control by se lectively braking the
wheels, and/or reducing engine power and
providing steering ass istance to help hold the
vehicle on the driver's intended course. The in­
dicator light
B.J in the instrument cluster
blinks when ESC is taking action to help you
control the vehicle.
ESC has limitations .
It is important to remem­
ber that ESC cannot overcome the laws of
physics.
It will not always be able to help out
under all conditions you may come up against.
For example, ESC may not always be able to
help you master situations where there is a
sudden change in the coefficient of friction of
the road surface. When there is a section of dry road that is suddenly covered with water,
slush or snow, ESC cannot perform the same
way it would on the dry surface. If the vehicle
hydroplanes (rides on a cushion of water in­
stead of the road surface), ESC will not be
able to help you steer the vehicle because con­
tact with the pavement has been interrupted
and the vehicle cannot be braked or steered .
During fast cornering, particularly on winding
roads, ESC cannot always deal as effectively
with difficu lt driving situations as at lower
speeds.
Always adjust your speed and driving style to
road, traffic §&and weather conditions. ESC
cannot override the vehicle's physical limits,
increase the available traction, or keep a vehi­
cle on the road if road departure is a result of
driver inattention. Instead, ESC improves the
poss ibility of keeping the vehicle under con­
trol and on the road dur ing extreme maneu­
vers by usin g the driver's steering inputs to
help keep the vehicle going in the intended di­
rection. If you are traveling at a speed that
causes you to run off the road before ESC can
provide any assistance, you may not experi­
ence the benefits of ESC.
ESC includes and/or works together with the
anti- lock brake system (ABS), brake assist sys -
tem and anti-slip regu lation (ASR). ESC is

A WARNING
-You should perform brak ing maneuvers
for the purpose of cleaning the brake
system only if road cond it ions permit .
Other road users must not be put at r isk -
yo u may cause an acc ident!
- Before descending a steep grade, reduce
speed and shift transm iss ion into a lowe r
gear or lowe r driving range. Do not ride
the brakes or hold the pedal down too
long or too often . This cou ld cause the
brakes to get hot and diminish braking
efficiency.
- Do not "ride the b rakes" by resting your
foot on the pedal when yo u do not intend
to brake . Th is may cause the brakes to
overheat, premature wear and increased
stopp ing distance.
- Under certain climat ic and operating
condit ions such as passing throug h wa­
ter, driving in heavy rai n or after wash ing
the vehicle, the effect iveness of the
brakes can be reduced. In winter, ice can
accumulate on the brake pads, lini ngs,
discs and d rums. Carefully apply brakes
f or a test . B rakes wi ll dry and ice coat­
ings wi ll be cleaned
off after a few ca re ­
ful brake applications.
- Driv ing for an ex tended pe riod of time on
salt -covered roa ds without using your
brakes can also affect braking efficiency.
Clean
off accumulated salt coating from
brake discs and pads with a few cautious
brake applicat ions.
- If you damage the front spoiler, or if you install a different spoiler, be sure the air
flow to the front brakes is not obstruct­
ed . Otherwise the brake system could
overheat reducing the eff ectiveness of
the ent ire brake system.
- Failure of one bra ke c ircuit will impair
the brak ing capability resulting in an in­
cr eased stopp ing distan ce. Avoid dr iv ing
the ve hicle and have it towed to the near­
est Aud i dea le r or q ualified workshop .
- Never le t the vehicle ro ll to a stop w ith
the engine shu t off.
Int ellig ent technolog y 145
-If the brake booster is not working, the
brake peda l must be pressed considera­
bly harder to make up for the lack of
booster assistance.
Electro-mechanical
power assist
The ele ctro-mechanical power assist helps
the driver when steering .
The degree of power assist is electronically
matched to veh icle speed.
The powe r steering system assists the driver
so that he can steer the vehicle with reduced
physical effort.
Power steer ing will not work if the engine is
off . As a result, the steering wheel will be hard
to turn .
A WARNING
If the system develops a problem, you
must seek qualified professiona l assis­
tance.
(D Note
-
If there is an electronic malfunction, ser­
votronic
will still function like a conven­
tiona l powe r steering system, providing a
constant steering support force tha t is no
l onger proportionate to the vehicle speed.
This is most noticeable when t urning the
steering wheel at low speeds (for example
when parking), - more effort w ill be re­
quired than usual.
- Be aware of the different than usual
steering response and adjust your steer­
ing force accordingly.
- Have the problem checked and set right
by an authori zed Aud i dea ler as soon as
possible.
- If a steering malfunction occurs, th is is
signa led w ith the
ls4 or .• indicator
lights and a warn ing tone, see. •

146 Intellig ent technolog y
-If the power steering system should fail,
or if the eng ine is not running (for exam­
ple, while being towed), yo u wi ll st ill be
able to steer the veh icle. However, more
effort will be requ ired to do so .
- If the power steering system is not func­
tioning properly, contact your authorized
Audi dealer immediately .
Driving with your
quattro
App lies to vehicles: with all-wheel drive
With all-wheel drive, all four wheels are driv­
en.
General information
W ith all-whee l drive , power is distributed to
a ll four wheels . This happens automa tica lly
depending on your dr iv ing sty le and the road
conditions at the time. See also ~
page 141.
The all-wheel drive concept is designed for
high engine powe r. You r vehicle is exception­
ally powerful and has ex ce ll ent dr iving charac ­
teristics bot h under normal driving conditions
and on snow and ice. Always read and fo llow
safety precautions ¢
.&..
Winter ti re s
When dr iving in the w inte r, your ve hicle w ith
a ll-wheel d rive has an advantage, even with
regular tires . In winter road conditions it may
be advisable to mount winter tires (or all-sea­
son tir es) for improv ed driveability and brak­
ing: these tires must be mounted on
a ll fo ur
wheels . See also ¢ page 195, Win ter tires.
Snow cha in s
Where tire chains are mandatory on certain roads, this normally a lso applies to vehicles
with a ll-wheel drive¢
page 196, Snow
chains.
Replacing whe els /t ires
Vehicles wit h all-wheel drive mus t always
have tires of the same size . Also avoid tires
with different tread depths. For details see page
q page 191, New tires and replacing
tires and wheels .
Off-Road driving ?
Your Aud i does no t have enough g round clear­
ance to be used as an off-road vehicle. It is
therefore bes t to avoid rough tracks and un­
even terrain as much as possib le . Also refer to
¢ page 150 .
A WARNING
-Always ad just your dr iv ing to road and traf-
f ic conditions. Do not let the extra safety
afforded by all-wheel drive tempt you into
taking extra risks.
- Although the all-wheel drive is very ef­
fective, always remember that braking capacity is lim ited by tire t raction . You
should therefore not d rive at excessive
speeds on icy or slippe ry road surfaces.
- On wet road surfaces, be careful not to
d rive too fast because the front whee ls
could begin to slide o n top of the water
(aquaplan ing). If th is should occur, yo u
will have no warning from a s udden in ­
crease in eng ine speed as wit h a front ­
wheel drive vehicle. Always drive at
speeds which are su ited to the road con­
d itions. -risk of crash.
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 per iod of t ime, the bat­
te ry is discharged by idling cur rent consume rs
(e .g. immobili zer) . In cert ain circumstances it
can resu lt in the re being insufficient energy
available to start the eng ine.
Intelligent energy management in you r vehi­
cle h andles the dis trib ution of e lectr ica l ene r­
gy. Start ing ability is ma rkedly improved and
the life of the battery is extended . .,._

-Never mount used tires on yo ur vehicle if
yo u are not sure of their "previous histo­
ry." Old used tires may have been dam­
aged 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 d riving, al­
ways stop as soon as it is safe to do so
and check the wheels and tires for dam­
age .
(D Note
-Please note that summer and winter
tires are designed for the cond itions that
are typ ic al in those seasons. Aud i recom­
