18 Instrument s and w arn ing /indic ato r light s
See your authorized Audi dealer as soon as
possible .
A WARNING
-If the B warning light does not go
out, or if it comes on while driv ing, the
ABS system is not working properly. The
vehicle can then be stopped only with
the brakes operating without ABS sup­ port . You will not have the protection
ABS provides. Contact you r A udi dealer
as soon as possible.
- USA models: If both, the~ warning
light and the Bwarning light come
on at the s ame t ime, the rear wheels
cou ld lock up first under hard braking.
Lock-up of the rear whee l brakes can
cause loss of vehicle control and an acci­
dent. Have yo ur vehicle repaired immed i­
ately by your authorized Audi dealer or a
qualified workshop. Dr ive slowly and
avo id sudden, hard brake applicat ion .
-Canada models: If both, the brake warn­
ing light . and the ABS warning light
II] come on at the same t ime, the rear
wheels co uld lock up first unde r hard
braking. Loc k-up of the rear wheel b rakes
can ca use loss of vehicle control and a n
acc iden t. Have you r vehicle repaired im­
me diately by your authorized Audi dealer
or a q ualified workshop. Drive slowly and
avo id sudden, hard brake applicat ion
~ Electro-mechanical power assist
If the indicator light illuminates w hile you are
driving, there is a malfunction i n the electro­
mechanical steering. If the ind icator light is
show ing
E'2:'~ . the re may be a red uction in pow­
e r stee ring assist. If the ind icator light is
show ing • • the re may be a tota l loss of pow­
e r steering assis t. T he steering must be in ­
spected immediate ly by a q uali fied wor ks hop
¢ .&, .With the engine not running (e.g . when
the car is being towed), there is a lso no powe r
assist ava ilable.
A WARNING
-
If there is a ma lfunction, the indicator
light for the electro-mechanical power as­
sist illuminates. Seek professional assis­
tance.

You should always lock the steering whenever
you leave your vehicle . This makes a vehicle
theft even more difficu lt ¢ & .
Ignition ke y safe ty lock
After switching off the ignition, the ig nit ion
key can only be removed from the ign ition
l ock 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.
Ignition on @
If it is difficult to turn the key after 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 mechan ism and
you will be able to turn the key freely and start the engine.
Starting the engin e@
In this position the engine starts . While the
engine is starting, the power supply to the headlights and other e lectr ica l consumers is
tempo rarily interrupted to conserve battery
power . After the engine has started, release
the key and it will return to posit io n @ .
Before the starter can be operated again the
key must be turned back to position@. The
non-r epeat lock prevents you from damag ing
the sta rter when the engine is runn ing .
A WARNING
-Never remove the key from the ign ition
lock whi le the vehicle is moving. The
steering wheel will lock causing loss of
control.
- If you have to leave your ve hicle -even
f or just a m in ute -always remove the ig­
ni tion key and take it with you. This is es­
pecially important if yo u a re going to
leave chi ldren behind in the vehicle. The
children cou ld 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 @ 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 ,& .
.,. Tu rn the ignition key to position ®
~ page 80, fig. 90 -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 contain 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 with 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 engine cannot be started by pushing
or towing the vehicle . .,..

86 On the road
Audi magnetic ride
Applies to vehicles: wit h magnet ic ride
Damping can be adjusted to the driver's pref­
erence and it adapts automatically to the cur­
rent driving situation.
Fig. 94 Cente r console: Switch for Audi magnetic r ide
" Press the sw itch r=) fig. 94 to tu rn spo rt set-
t ing o n or off.
Aud i magnetic ride is an electron ically con­
trolled damp ing system . Th is chassis system
assists the driver by adapti ng to the par ticular
situatio n th rough imper cep tible con trol p roc­
esses. The
damping provides individual mod u­
l ation of damping forces. For example, with
dampi ng characterist ics set to p rovide greater
comfort, damping is set somewhat harder for
a brief period only as required, when rounding
a curve and when braking.
Standard setting
Select the standard sett ing if you prefer a sus­
pension setting emphasizing comfort.
Sport setting
Select the sport setti ng if you prefe r a sporty
suspe nsio n setting . The LED in the sw itch
E
comes on to indicate spo rt setting .
@ Tips
The warning/indicator light E in the instru­
men t clus ter comes on in the even t of a
malf unction . Drive to the closest au thor ­
ized Audi dealer as soon as possible and
have the malfunction repaired.
Sport mode
Applies to veh icles: w ith Sport bu tton
Fig . 95 Button in t he ce nter console
.,. To switch sport mode on, press the button
in the center console. The indicator light
t ur ns on .
" To swit ch spor t mode off, press the but ton
in the center console again. The indicator
light turns on .
A mo re agile and spo rty d riv ing style is possi­
ble when driving the vehicle in "sport mode".
T his mode affec ts thrott le response and the
sound of the engine, the steering characteris­
t ics for a more direct power steering response
and the damping characteristics of the Audi
magnetic ride for dynam ic suspension tu ning.
(D Tips
If there is a malfunction in the retractable
rear spoiler* or the Aud i magnetic ride *, it
may not be poss ible to activate sport
mode.

Anti-lock brake system (ABS)
ABS prevents the wheels from locking under braking.
The anti-lock brake system (ABS) makes a ma­
jor contribution to increasing active dr iving
safety. You should not expect that braking d is ­
tances will be
shortened under all circumstan­
ces with ABS. Braki ng d istance may even be­
come somewhat
longer, for example, on grav­
e l or in new snow on slippery g round, even if
you are driving care fully and s low ly.
ABS operation
When a vehicle speed of about 10 mph (20
km/h) is reached, an automatic test sequence
is run. Some noise from the pump may be au­
d ible.
I f the speed of a wheel slows down too much
r e lative to veh icle speed and it starts to lock,
brake pressure to this wheel is reduced. This
ad justment process can be felt as a
pul sin g
moti on of the br ake pedal , accompanied by
some noises. You as the driver are intentiona l­
ly being given the information that the whee ls
are tending to lock (ABS control range). In or ­
der for ABS to be able to operate optimally in
this range, you must keep the brake pedal de­ pressed - do not "pump the brakes ".
Brake a ssist ant
The brake power assist unit increases the
pressure that you generate with the brake
pedal. It works only w hen the eng ine is run­
ning .
Automatic full br ak ing
This function allows full brak ing in spite of
high brake pedal forces (e.g. when the brakes
are severely stressed because the vehicle is
fully loaded) . The driver notices th is function
throug h a reduction of pedal force and in ­
creased pedal travel. When the brake pedal is released, fu ll braking assist switches off again
automatically .
Intellig ent technolog y 153
If there is an ABS failure, the b rake assistant
and automatic fu ll braking assist are not avail­
able.
A WARNING
- ABS cannot suspend the laws of physics.
You should keep th is in mind in particu­
lar on an icy or wet road . If ABS control
of braking intervenes, you should adjust
your speed immed iately to road and traf­
fic conditions. Do not be tempted by the increased safety provided to take risks -
danger o f an accident .
- Please keep in mind tha t the risk of an
accident is increased by driving too fast,
particularly in bends and on icy or wet
roads, and by driving too close to the ve­
hicle ahead . The increased risk of an acci­
dent cannot be reduced by the brake as­
sistant - danger of an accident.
(D Tips
If a malfunction occurs in the ABS, this is
s ignalled by an indicator light, see
<=:> page 17.
Electro-mechanical
power assist
The electro-mechanical power assist helps
the driver when steering .
The degree of power assist is electronically
matched to vehicle speed.
The power steering system assists the driver
so that he can steer the vehicle with reduced physical effort .
Power steering 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.

154 Intelligent technology
If there is an electronic malfunction, ser­
votronic
w ill st ill function like a conven­
tional power steer ing system, prov iding a
constant steer ing support force that is no
longer proportionate to the ve hicle speed .
This is most noticeable when turning the
steer ing whee l at low speeds (for examp le
when par kin g), -more effo rt will be re­
qui red th an usual.
- Be aware of the different than usual
stee ring response and adjust you r steer­
i ng force a ccord ingly.
- Have the p roblem chec ked and set right
by an authori zed Audi dealer as soo n as
poss ib le.
- If a stee ring malfunct io n occu rs, this is
s ignaled with the
42J or .• indic ator
li ghts and a wa rning tone, see.
(D Tips
- If the power steering system shou ld fa il,
or if the eng ine is no t runn ing (fo r exam ­
ple, while being towed), yo u wi ll st ill be
able to stee r the veh icle. However, more
effort will be req uired to do so .
- If the power steer ing system is not func ­
tioning p roperly , contact your a uthorized
A udi dealer immediate ly .
Driving with your
quattro ®
With All Wheel Drive, all four wheels are driv­
en.
General inform ation
W ith All Whee l Dr ive, power is d istributed to
all four wheels. This happens automatically
depending on your dr iv ing sty le and the road
conditions at the t im e. See also ¢
page 149,
E lectronic differential lock (EDL) .
Winter tires
When driving in the winter, your vehicle w it h
All Wheel Drive has an advantage, even with regular t ires. In winter road co nditions it may
be adv isable to mount winter tires (o r all-sea- son tires) for
improved driveability and brak ­
ing : these tires must be mounted o n
all four
wheel s.
See also ¢ page 209, Winter tires .
Snow chains
Where tire chains a re m andatory o n certa in
roads, this no rma lly also app lies to ve hicles
wi th All Wheel Drive
¢ page 210, Snow
chains.
Replacing wheels /tires
Vehicles wi th A ll Wheel D rive mus t always
have t ires of the same s ize. A lso avoid tires
with different tread depths . For deta ils see
page ¢
page 205, New tires and replacing
tires and wheels .
Off-Road driving?
Your Aud i does not have enough g ro und clea r­
an ce 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 158.
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 Dr ive tempt you into
taking ext ra ris ks.
- 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 s urfa ces.
- On wet road surfaces, be careful not to
drive too fast because the front whee ls
could begin to slide o n top of the wate r
(aquapla ning). 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 veh icle. Always drive at
speeds which are su ited to the road con­
d itions. -risk of crash.

-Never mount used tires on yo ur vehicle if
you 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.
