Drive carefully to the nearest authorized
Audi dealer or other qualified workshop and have the malfunction corrected.
- If the brake warning/indicator light does
not go out after a few seconds and the
park ing brake is released, or lights up
wh ile you are driving, the fluid level in
the brake fluid reservoir is too low.

immediately at low speed to the nearest
au thorized Audi dealer or qualified work ­
shop and have the brake system inspect­
ed.
-Always keep in m ind that afte r several
brake applications, yo u will need greater
pressure on the brake peda l to stop your
vehicle. Do not re ly on stra ined brakes to
respond w ith maximum stopp ing power
in critical situations. You must a llow for
increased brak ing dista nces. The extra
distance used up by fad ing brakes could
lead to an acc ident.

Your vehicle is equipped with an electrome­
chanical parking brake. The parking brake is
designed to prevent the vehicle from rolling unintentionally and replaces the hand brake.
In addition to the normal functions of a tradi­
tional hand brake, the electromechanical
parking brake provides various convenience
and safety functions .
When starting from rest
- The integral starting assist helps you when
driving by automatically releasing the park­
ing brake ¢
page 88, Starting from rest.
-When starting on inclines , the starting as-
sist prevents the vehicle from unintentional-
ly rolling back. The braking force of the
parking brake is not released until sufficient

page 89, Emergency braking .
8_ WARNING
If a gear or a drive range (automatic trans­
mission) is engaged with the vehicle sta­
tionary and the engine running, you must in no instance accelerate or release the
clutch* carelessly. Otherwise the vehicle
will start to move immediately -risk of an
accident .
(D Tips
-If the parking brake is applied with the
ignition switched off, the indicator lights
i n the sw itch and -(USA models)/ .
(Canada models) in the instrument clus­
ter will go out after a certain per iod of
time .
- Occas iona l noises when the park ing
brake is applied and re leased a re no rma l
and are not a ca use for concern.
- Wh en the vehicle is parked, the parking
brake goes through a se lf-test cycle a t
regular intervals. Any assoc iated noises
are no rma l.
Parking
.. Press the brake peda l to stop the v ehicle .
.. Pull the switch @c::>
pag e 87, fig. 101 to set
the parking brake .
.. Automatic transmiss ion: Move the selector
lever to P .
.. Turn the eng ine off c::>
&_ .
.. Manua l transm ission: Shift into 1st gear .
.. When on incl ines or decli nes, tu rn the steer ­
i ng wheel so th at the vehicle will roll into
the curb if it begins to move .
8_ WARNING
-When you leave your vehicle -even if on­
ly briefly -always remove the ignition
key . Th is applies particularly whe n chil­
dren remain in the vehicle . Otherwise the
children could star t the eng ine , release
the par king brake or operate electrical
equipme nt (e.g. power windows). There
is the risk of an accident.
- W hen the veh icle is locked, no one -pa r­
ticularly not children should remain in
the vehicle . Locked doors make it more
difficult for emergency worke rs to get in­
to the vehicle -putting lives at risk .
· Starting from rest
The starting assist function ensures that the
parking broke is rel eased automatically upon
starting.
Stopping and appl ying parking brake
.. Pull the sw itch @c::> page 87 , fig. 101 to ap-
p ly the parking bra ke.
Starting and automatically releasing the
parking brake
.. When you start to dr ive as usual, the p ark ­
ing bra ke is automatica lly released and your
vehicle begins to move .
When stopping at a t raffic signal or stopping
in city t raffic on vehicles with an a utomatic
t ransmission, the parking brake can be ap­
plied. The vehicle does not have to be held
with the footbrake . The parking brake elimi­
nates the tendency to creep w ith a dr ive range
engaged. As soon as you drive off as usual,
the parking brake is re leased automat ically
and the vehicle starts to move .
Starting on slop es
When starting on inclines, the starting assist
prevents the vehicle from un in tent ionally roll­
ing back. The braking force of the parking
brake is not released until suffic ient driving
force has been built up at the wheels .

@ Tips
For safety reasons, the par king brake is re­
leased au tomatically only when the dr iv­
er 's safety belt is engage d in the buckle.
Starting off with a trailer
To prevent rolling back unintentionally on an
incline , do the following:
~ Keep the switch @¢ page 87, fig . 101
pulled and depress the accelerator. The
park ing brake stays app lied and prevents
the vehicle from rolling backward.
~ You can release the switch @once you are
sure that you are develop ing enough dr iv ing
force at the wheels by depress ing the accel­
erator .
Depending on the weight of the r ig (vehicle
and trailer) and the severity of the incl ine, you
may roll backwards as you start . You can pre­
ve nt rolling backwards by holding the parking
b rake sw itch @pulled out and accelerating -
jus t as you would whe n starting on a hill with
a conventional hand brake.
Emergency braking
In the event that the conventional brake sys ­
tem fails or locks.
~ I n an eme rgency, pull the sw itch @
¢page 87, fig. 101 and continue to p ull it
to s low your vehi cle down wi th the pa rk ing
brake .
~ As soon as you release the switch @ or ac-
ce lerate, the braking process stops.
I f you pull the switch @and ho ld it above a
speed of about 5 mph (8 km/h), the emergen ­
cy braking function is initiated . The vehicle is
braked at a ll four wheels by activating the hy­
draulic brake system. T he brake performance
is similar to making an emergency stop ¢
&. .
In order not to activate the emergency brak ­
ing by m istake, an a udible warning tone (buz­
zer) sounds when the switch @is pulled. As
soon as the switch @ is released, or the accel-
On th e ro ad 89
erator peda l is depressed, eme rgency braking
stops.
A WARNING
Emergency braking should only be used in
an emergency, when the norma l foot brake
has fa iled or the brake pedal is obstructed.
Using the parking brake to perform emer­
gency b rak ing will slow your vehicle down
as if you had made a full bra ke application .
T he laws of physics cannot be suspended
even with ESC and its asso ciated compo­
nents (ABS, ASR , EDS) . In corners and
when road or weathe r conditions are bad,
a full brake application can ca use the vehi­
cle to sk id or the rear end to break away -
risking an accident.
Speed warning system
Overv iew
The speed warning system helps you to keep
your driving speed below a set speed limit.
The speed warn ing system warns if the driver
exceeds a previous ly stored max imum speed.
A war ning tone w ill so und as soon as the vehi­
cle speed exceeds the set speed by about 3 mph (3 km/h). At the same time, a warn ing
symbol appears in the display. The symbo l's
appearance might be different in some mod ­
els.
T he speed wa rn ing system has one or two*
warning thresholds that func tion independ ­
en tly of each othe r and that have somewhat
different purposes:
Speed warning 1
You can use speed warn ing 1 to set the maxi­
mum speed while you are d riving. This se tting
will re ma in in effec t unti l yo u t urn
off the ig ni­
tion, assuming that yo u have no t changed or
reset the setting.
