BRAKE/ This warning/indicator light illuminates when
the brake fluid level is too low or when there
is a malfunction in the ABS, or when the park ­
ing brake is set.
If the - (USA models)/ . (Canada
models) symbol flashes in the disp lay with the
parking brake released, there is a ma lfuncti on
in the brake system . In addition to the sym­
bol, one of two messages appears in the dis­
play:
Stop vehicle and check brake fluid level
Stabilisation program and ABS fault! See
Owner's manual
.. Pull off the road and stop the vehicle.
.. Obtain professional ass istance.
USA models: if there is a malfunction in the
ABS system, the
r.1il warning/indicator light
illuminates along with the - system
malfunct ion warn ing/ indicator light
q ,&..
Canada models: if there is a malf unction in
the ABS system, the
ll] warning/ind icator
light illuminates together with the. brake
system malfunction warning/indicator light
c::>,&. .
The light - (USA)/ . (Canada) illumi­
nates when the ign ition is turned on . It goes
out after the engine has been started and the
parking brake is fu lly released . This indicates that the brake
warning light is functioning
properly.
If the brake warning light does not light up
when the engine is cranking or the parking
brake is applied, there may be a malfunction
in the electrical system. In this case, contact
your Audi deale r.
If the ABS fails, the ABS warn ing/ indicator
light
r.1il (USA models) /ll] (Canada models)
flashes together with the brake system warn­ ing/ indicator light
i:::> .&..
(USA mode ls): If the warn ing light - and
the warning light
EiJ illuminate together, im­
mediate ly contact your authorized Audi dea ler
or qualified workshop to have all brake pads
inspected
i:::> page 19.
When the light comes on, an audible warning
signal is also given.
Parking brake set
The parking brake war ning ligh t-·
(Canada models) illuminates when the park­
ing brake is set. In addition, a warning tone

A WARNING
-Always observe the warnings in
¢page 187, Engine comportment, be­
fore opening the engine hood and check­
ing the brake fluid.
- Driving with low brake fluid is a safety
hazard! Stop the car and get profess ional
assistance.
- USA models:: If both, the 1111 warning
light and
the m warning light come
on at the same time, the rear wheels
could lock up first under hard braking.
Lock-up of the rear wheel brakes can
cause loss of vehicle cont rol and an acci­
dent. Have your vehicle repaired

22 Instruments and warning /indicator lights
When this symbo l ml illuminates, it means
that Adaptive Light is defective. Go to a quali­
fied workshop to have the headlights or the
control unit for the Adaptive L ight repaired.
@, o Light/rain sensor defective
App lies to vehicles: with automat ic headlights
The indicator light indicates a defect in the
automatic headlights/automatic wiper sys ­
tem .
If the symbo l illuminates, the light sensor has
failed. For safety reasons , the low beams are
turned on permanently with the switch in
AU­
TO . However, you can continue to turn the
lights on and off using the light switch . In the
case of a defect in the rain sensor , the w ind­
sh ield wiper lever functions are st ill available .
H ave the light/ra in sensor checked as soon as
possible at an authorized Audi dealer.
; Audi magnetic ride
Appl ies to vehicles: with Audi magnetic ride
The indicator light monitors vehicle damping.
The indicator light E illuminates when the ig­
nition is switched on as a function check.
@ Tips
If the indicator lamp illuminates while you
are driving, there is a malfunct ion in the
veh icle damping. The chass is should be in­
spected immediately by an authorized Au­
di dealer.
~ Diesel particulate filter clogged
Applies to vehicles: with diesel engine and diesel particu­
late fi lter
1/1 Particulate filter ! See owner's manual
If the indicator light II in the instrument
cluster comes on, the diesel particulate filter has become blocked with soot as the result of
constant short-distance driving. When the
II symbol illuminates, you can alter your
driving style to assist the filter self-clean ing
p rocess. Drive for approximately 15 minutes
in 4th or 5th gear (automatic transmission with the se
lector lever in the S position) at a
minimum speed of 37 mph (60 km/h) and an
engine speed of approx imately 2,000 RPM .
The temperature increase that will result from
this can burn off the soot in the filter. The
symbol will switch off when the cleaning is
successful. After a successful cleaning, there
is no need to bring the car to an authorized
dealer or qualified workshop because this is
part of normal vehicle operation .
If the symbol
DI does not switch off, see
your autho rized dea ler or other qualified
workshop to have the problem corrected .
As long as the indicator light
11!1 remains on
(diesel part iculate filte r plugged), you ca n ex­
pect increased fuel consumption and possibly
also a loss of engine performance.
For more information on the diesel particu­
late filter, refer to~
page 171 .
A WARNING ,__
Always adapt your speed to the current
weather, road and traffic conditions. You
should never disobey traffic laws in order
to follow driving recommendations .
¢ ¢Turn signals
-
The indicator light blinks when you use either
turn signal.
Whenever you use the left B or the right fl
turn s ignal, the indicato r light blinks . When
you use the emergency f lasher, both indicator
lights flash.
If one of the turn signal light bulbs burn out,
the turn signal will blink twice as fast as nor­
mal.

switch the sys tem on.
• Drive at the speed you wish to set .
• Press b utton @ to set that speed .
The display
¢fig. 106 will show the set s peed .
The display may v ary depending on t he type o f
display in yo ur vehicle. The indicator
light

will also light up in the instrument cluster.
A WARNING
- Always pay attention to traffic even when
the cruise control is switched on . You are
always responsible for your speed and
the distance between yo ur vehicle and
othe r vehicles .
- For safety reasons, the c ruise control
sho uld not be used in the city, in stop­
and -go traff ic, on twist ing roads an d
when ro ad conditions are poo r (such as ice,
fog, gravel, heavy rain and hydro­
plan ing) -risk of accident.
- Turn off the cruise contro l temporarily
when enter ing turn lanes, highway exit
lanes or in construction zones.
- Please note that inadvertently "resting"
your foot on the accelerator pedal causes
the cruise co ntrol not to brake. This is
because the cruise control is over ridden
by the dr ive r's acceleration.
(D Tips
- Veh icles with man ual transmiss ion: You
can attai n the set speed only if the cur­
rently engaged gear allows it and the en­
gine is not stressed . Sh ifting to a highe r
o r low er gea r promptly will a llow the en­
gine to r un smooth ly.
- The cr uise control can not mainta in a

lever pressed down, you will alter your speed
in S mph (10 km/h) increments.
You can also press t he accelerator pedal down
to increase your speed, e.g. if you want to
pass someone. The speed you saved earlier
will resume as soon as you release the acceler­
ator pedal.
If, however , you exceed yo ur saved speed by
5 mph (10 km/h) for longer than 5 minutes,
the cru ise control will turn off temporari ly.

Audi magnetic ride
Applies to vehicles: with magnetic ride
Damping can be adjusted to the driver's pref­
erence and it adapts automatically to the cur­
rent driving situation .
Fig. 107 Center console: Sw itch for Aud i magnet ic ride
.,. Press the switch c:> fig. 10 7 to turn sport
sett ing on or off.
Audi magnet ic r ide is an electronically con­
trolled damping system . This chassis system
ass ists the driver by adapting to the particular
s ituat ion through imperceptible control proc­
esses. The
damping provides individual modu­
lation of damping forces. For example, with
damping characteristics set to provide greater
comfort, damping is set somewhat harder for
a brief period on ly as required, when rounding
a curve and when braking.
Standard setting
Select the standard setting if you prefer a sus­
pension setting emphasizing comfort.
Sport setting
Select the sport setting if you prefer a sporty
suspension setting. The L ED in the switch
E
comes on to ind icate sport setting .
(D Tips
The warning/indicator light E in the instr u­
ment cluster comes on in the event of a
malfunction. Drive to the closest author­
i zed Audi dealer as soon as possible and
have the ma lfunction repa ired.

Stopp ing on an incline
"' Always hold the vehicle with the footbrake
or parking b rake in order to p revent "roll ­
back"
¢ A . Do not try to prevent the vehi­
cle from rolling back by revving the engine
while it is in gear.
St artin g on a h ill
"' Apply the hand brake fi rm ly.
"' With the engine in gear, gradua lly acce ler-
ate and release the hand brake.
The engine can only be
s tar te d with the selec ­
tor lever in P o r N
c::> page 90 . At low ambient
temperatures
(14 °F /-10 °C), it is only possi­
b le to start the engine with the selector lever
in
P.
When parking on level ground , it is sufficient
to p lace the se lector lever in
P. On a steeply
sloping road, you should first apply the park­
ing brake firmly and then place the selector
lever in
P. This way, you do not overload the
pawl mechanism and it is eas ier to move the
selector lever out of P .
A WARNING
-Never leave your vehicle with the eng ine
running wh ile in gear. If you must leave
yo ur vehicle wi th the engine running, set
the parking bra ke and engage the pa rk
lock.
- When the engine is running and the
transmission is in gear (D, Sor
R) or in
"tiptronic" mode, it is essentia l that you
stop the vehicle with the footbrake .
When idling, the transmission of power
does not stop completely -the vehicle
"creeps".
- Do not accelerate when you change the selector lever position with the vehicle
stationary and the engine running - risk
of an accident!
- Never place the selector lever in the R or
N position while the vehicle is moving -
risk of an accident!
- If you have to bring your vehicle to a stop
wh ile on an incl ine, keep the foot brake
Tran sm iss ion 99
depressed all the way down so that the
veh icle does not sta rt to roll backward.
You should never ho ld the vehicle us ing
the clutch if you are going to be stopped
on an incl ine.
If you do, the clutch w ill
start to slip when it ove rheats caused by
the constan t overload. This is dangerous
bec ause if the vehicle starts to roll bac k­
ward, yo u co uld cause an acc iden t.
If the
clutch should start to slip, you wi ll feel
the vehicle "jerk" and the se lector lever
disp lay w ill start blink ing.
- Before driving down a steep slope , re­
duce your speed and shift into a lower
gear with "tiptronic".
- Do not ri de the brakes or apply the brake
pedal too often or too long. Constant
brak ing causes the brakes to overheat
and substantially reduces braking per­
formance, increases braking d istance or
causes complete fa ilu re of the brake sys­
t e m .
, Hill Descent Assist
App lies to vehicles : wi th S tronic t ra nsmi ssio n and H ill
D escent Ass ist
Hill Descent Assist helps the driver when driv ­
ing down inclines.
Hill Descent Assist is activated by pressing the
brake while descending when the se lector lev­
er is in
0 /5 . The S tronic transmission auto­
matically shifts down to a gear suitable for
the incline. H ill Descent Assist attempts to
maintai n the current veh icle speed w hen the
braking occu rs, as far as physical and techn i­
ca l lim its allow .
It may be necessa ry to adjust
the speed using the bra kes.
Hill Descent Assist sw itches off when the in­
cli ne leve ls out o r when the gas peda l is p ress ­
ed.
On vehicles with cruise control*
