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

A WARNING
-When driving, do not leave any hard ob­
jects on the rear window shelf or allow
your pet to sit on the shelf. They could
become a hazard for vehicle occupants in
the event of sudden braking or a crash .
- Always remove objects from the instru­
ment panel. Any items not stored could
slide around inside the vehicle while driv­
ing or when accelerating or when apply­
ing the brakes or when driving around a
corner.
- When you are driving make sure that
anything you may have placed in the cen­
ter console or other storage locat ions
cannot fall out into the footwells. In case
of sudden braking you would not be able
to brake or accelerate.
- Any articles of clothing that you have
hung up must not interfere with the driv­
er's view. The coat hooks are designed
only for lightweight clothing. Never hang
any clothing with hard, pointed or heavy
objects in the pockets on the coat hooks.
During sudden braking or in an accident -
especially if the airbag is deployed - these objects could injure any passen­
gers
inside the vehicle.
- To reduce the risk of personal injury in an
accident or sudden stop, always keep the
glove compartment closed while driving.
- Read and follow all WARNINGS
c:> page 173, Important safety instruc­
tions on the side airbag system.

not impair the driver's vision.
- The coat hooks must only be used for
lightweight clothing. Do not leave any
heavy or sharp edged objects in the pock­
ets which may interfere with the side cur­
tain airbag deployment and can cause personal injury in a crash.
- Do not use coat hangers for hanging clothing on the coat hooks as this can in­
terfere with proper deployment of the
side curta in airbags in an acc ident.
- Do not hang heavy objects on the coat
hooks, as they could cause personal in­
jury in a sudden stop.

vehicles or obstacles that are not moving
can trigger a collision warning and if con­
firmed by the video camera, an acute col­ lis ion warn ing.
- For safety reasons, do not use adaptive
cruise control when driving on roads with
many curves, when the road surface is in
poor condit ion and/or in bad weather
(such as ice, fog, gravel, heavy rain and
hydroplan ing). Using the system under
these cond itions cou ld result in a co lli ­
sion .
- Switch adaptive c ruise control off tempo­
rar ily when driv ing in turning lanes, on
expressway exits or in construction
zones . This prevents the vehicle from ac­
celerating to the set speed when in these
situations .
- The adapt ive cru ise control system w ill
not brake by itse lf if you put your foot on
the accelerator pedal. Doing so can over­ ride the speed and distance regulation .
- When approaching stationary objects such as stopped traffic, adaptive cruise
control will not respond and braking
guard w ill have limited function.
- The adapt ive cruise control system and
braking guard do not react to people , an­
ima ls, objects crossing the road o r on­
coming objects .
- The function of the radar sensors can be
affected by reflective objects such as
guard ra ils, the entra nce to a tunnel,
heavy rain or i ce.
- Never follow a veh icle so closely that you
cannot stop your vehicle safe ly. The
adaptive cruise cont ro l c anno t slow or
brake the veh icle safely when you follow
another vehicle too closely. Always re­
member that the automatic braking
funct ion cannot bring the veh icle to a
sudden or emergency stop under these
conditions .
- To prevent unintended operation, always
switch ACC off when it is not be ing used. (D Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. That cou ld affect the adaptive
cruise control system and brak ing guard .
Have your authorized Aud i dea le r or a u­
thorized Audi Serv ice Facility check their
funct ion.
