Pa rking br ake: syste m fault! Ple ase c ont act
deale r
-If the indicator ligh t and the message ap­
pear
w hen stationar y or aft er sw itchin g the
ign it io n on ,
check if you can release the
park ing brake . After re leas ing the parking
brake, carefu lly drive to your authori zed
Audi dealer immed iately to have the mal­
function corrected. If you cannot re lease the
parking brake, seek professional assistance .
- If the indicator light and the message ap­
pear
w hile dr ivin g, the emergency braking
function may not be ava ilable . It may not be
poss ible to set the parking brake o r release
it once it has b een set. Seek professional as­
s istance.
(USA models): If the warning light
1111 and
the warning light
EiJ appear together, imme­
d iate ly contact your authorized Aud i dealer or
qua lified workshop to have all b rake pads in­
spected
Q page 20 .
When the light comes on, an audible warning
signal is also give n.
A WARNING
- Always observe the wa rnings in
Q page 231, before opening the hood
and checking the brake fluid .
- Driv ing with low b rake fluid is a safety
haza rd. S top the car and get professional
assista nee .
- If the
1111 (USA models)/ . (Canada
mode ls) b rake system indicator light
turns on together with the ABS and ESC indicator lights, the ABS/ESC regu lating
function may have failed. F unctions that
stabilize the vehicle are no longer availa­
ble. Th is could cause the vehicle to
swerve and increase the risk of sliding .
Drive carefully to the nearest authorized
Audi dealer or other qualified workshop
and have the malfunction cor rected.
- If the brake warning/indicator light does
not go out afte r a few seconds and the
par king brake is released, or ligh ts up while you are driving, the fluid leve
l in
the brake fl uid reservo ir is too low. If you
believe that it is safe to do so, proceed
immed iate ly at low speed to the nearest
author ized Audi dealer or qualified repair
facility and have the brake system in­ spected.
- Always keep in mind that after severa l
brake applications, you will need greater
pressu re on the brake pedal to stop you r
veh icle. Do not rely on st rained bra kes to
respond with maximum stopping powe r
in critical situations . You must allow for
increased braking distances . The extra
distance used up by fading brakes could
lead to an accident.
PARK/( ®) Electromechanical parking
brake
The warning/indicator light monitors the
electromechanical parking brake .
If the indicator light - (USA models) /.
(Canada models) turns on, th@ parking brake
was set. If the parking brake is set when the
ignition is off, the indicator light turns off af­
ter about 20 seconds.
The warning/indicator light will go out when
the parking brake is re leased.
- (USA model s) ,. (Canada model s)
Caut io n: Vehicle parked too steep
If the indicator light blinks and the message
appears, there is not enough braking power to
keep the vehicle from rolling. The brakes have
overheated. The vehicle could roll away even
on a small incl ine .

Ill Parking brake!
If the II indicator light turns on and this
message appears, there is a parking brake
malfunction. Drive to your authorized Aud i
dealer or qualified wo rkshop immediately to
have the ma lf u nction corrected .
-l Engine cooling system malfunction
A malfunction in the engine cooling system
must be repaired as soon as possible.
• Switch off engine and check coolant level
If the indicator light turns on and the mes­
sage appears, the coolant temperature is too
high or the coolant level is too low.
• Pull off the road.
• Stop the vehicle.
•Turnoff the engine.
• Check coolant level ¢
page 240.
• Add coolant if necessary ¢ page 240.
• Continue driving only after the eng ine cool­
ant warning/ indicator light goes o ut.
• Contact your authorized Audi deale r for as-
sistance if necessary .
If the engine coolant level is correct, then the
radiator fan may be the cause of the malfunc­
tion.
• Coolant temperature too high! Please let
engine run with vehicle stationary
If the indicator light turns on and the mes ­
sage appears in trailer mode*, let the engine
run at id le for a few m inutes to cool down.
A WARNING
-If your vehicle should break down for
mechanical or other reasons, park at a
safe distance from moving traffic, turn
off the engine and turn on the hazard
wa rning lights ¢
page 47, Emergency
flasher.

A WARNING
-==
- When you leave your vehicle -even if on-
ly briefly -always take the ignition key
with you. This applies particularly when
children remain in the vehicle. Otherwise
the children cou ld start the engine, re­
lease the parking brake or operate elec­
trical equipment (e.g. powe r wi ndows).
T here is the r is k of an accident.
- When the veh icle is locked, no one -par­
ticularly not children should rema in in
the vehicle. Locked doors ma ke i t mo re
diff icult for emergency wo rke rs to ge t in­
to the veh icle -putt ing lives at risk.
Starting from rest
The starting assist function ensures that the
parking broke is released automatically upon starting.
Stopping and applying park ing brake
.. Pull the sw itch(®) to apply the parking
brake .
Starting and automatic ally releasing the
parking brake
.. When you sta rt to dr ive as usual, the park­
ing brake is automatically released and your
veh icle begi ns to move.
When stopping at a traffic signal or stopping in city traff ic, the parking brake can be ap-
plied . The vehicle does not have to be he ld

with the footbrake . The parking brake elimi­
nates the tendency to creep with a drive range
engaged . As soon as you dr ive off as usual,
the park ing brake is released automatically
and the vehicle starts to move.
Starting on slop es
When starting on inclines, the starting assist
prevents the vehicle from unintentiona lly ro ll­
ing back. The braking force of the parking
brake is not released until sufficient driving
force has been bu ilt up at the wheels.
For safety reasons, the park ing brake is re­
leased automatically only when the dr iv­
er's safety belt is engaged in the buckle.
Starting off with a trailer
To prevent rolling back unintentionally on an
incline, do the following:
.. Keep the switch(®) pulled and depress the
acce lerator. The parking brake stays applied
and prevents the vehicle from ro lling back­
ward.
.. You can release the switch (®) once you are
sure that you are develop ing enough for­
ward momentum at the wheels as you de­
press the accelerator.
Depending on the weight of the r ig (vehicle
and tra iler) and the severity of the incl ine, you
may roll bac kwards as you sta rt. You can pre­
vent roll ing backwards by holding the parking
b rake switch (®) p ulled out and acce lerat ing -
just as you would when starting on a hill with a conventional hand brake.
Emergency braking
In the event that the conventional brake sys ­
tem fails or locks .
.. In an emergency, pull the switch(®) and
contin ue to p ull it t o slow your vehicle down
with the parking brake.
.. As soon as you release the switch (®) or ac­
ce lerate, the braking process stops.
If you pull the switch(®) and hold it above a
speed of about 5 mph (8 km/h), the emergen­
cy bra king f unct ion is initiated. The vehicle is
braked at all four whee ls by activating the hy­
draulic brake system. The brake performance
is simila r to making an emergency stop
c> .&. .
In order not to act ivate the emergency brak­
ing by mistake, an audib le warning tone (buz­
zer) sounds when the switch(®) is pulled. As
soon as the sw itch (®) is re leased, or the accel­
erato r pedal is depressed, eme rgency braking
stops .
.&, WARNING
E mergency braking should only be used in
a n emergen cy, when t he norma l foot bra ke
has fa iled or the brake pedal is obstructed.
Using the par king brake to perform emer ­
gency b raking will s low your vehicle down
as if you had made a full brake application.
The laws of physics cannot be suspended
even with ESC and its associated compo­ nents (ABS, ASR, EDL). In corners and
when road o r weathe r cond itions are bad,
a full brake application can cause the v ehi­
cle to s kid or the rear end to break away -
r isking an a cci den t.
Start-Stop-System
Description
Appl ies to vehicles : wit h Start-Stop-System
The Start-Stop-System can help increase fuel
economy and reduce CO2 emissions .
In the Start -Stop -mode, the engine shuts off
automat ica lly when the veh icle is stopped,
such as at a traffic light. The ignition remains
switched on during this stop phase. The en­
gine wi ll be automat ica lly restarted when
needed .
The last Start-Stop-System setting (on/off us­
ing the button
l 0a• I) will be restored when the
ignition is turned on. The LED in the !09 ~1 but­
ton turns on when the Start-Stop-System is swit ched off manually.
