diately by your authorized Audi dealer or a qualified workshop .
Drive slowly and avoid sudden , hard brake applications.
• If the brake warning /indicator light does not go out after a few
second s and the parking brake released , or lights up while you are
driving , the fluid level in the brake fluid reservoir i s too low. If you
believe that it is safe to do so , proceed immediately at low speed
to the neare st authorized Audi dealer or qualified repair facility
and have the brake system inspected .
• Always keep in mind that after several brake applications, you
will need greater pressure on the brake pedal to stop your vehicle.

the switch at the same time to release the parking brake.
The indicator light in the switch goes out.
Your vehicle is equipped with an electromechanical parking brake.
The parking brake is designed to prevent the vehicle from rolling
unintentiona lly and replaces the hand brake. In addition to the normal functions of a traditional hand brake, the
electromecha
nical parking brake provides various convenience and
safety functions.
When starting from rest
• The integral starting assist helps you when driving by automati­
cally releas ing the parking brake=>
page 111, "Starting from rest".
• When starting on inclines, the starting assist prevents the vehicle
from unintentionally ro ll ing back. The braking fo rce of the parking
brake is not released until suff icient driving force has been built up at
the whee ls.
Emergency brake function
An emergency brake ensures that the vehicle can be slowed down
even if the
normal brakes fail=> page 112, "Emergency braking" .

& WARNING (continued)
• Please note that unconsciously "resting" your foot on the
accelerator pedal causes cruise control not to brake. This is due to
the control system being overridden by the driver's acceleration.
• If a brake system malfunction such as overheating occurs when
the cruise control system is switched on, the braking function in
the system may be switched off. The other cruise control functions remain active as long as the indicator light
CRUISE (US model) / (;f
(Canadian model) is on.
(I) Tips
The brake lights illuminate as soon as the brakes apply
automatically. •

& WARNING (co ntinued )
• Always turn off adaptive crui se control when entering turn
lanes, highway ex it lanes and con struction zones or similar situa­
tions because the vehicle will automatically accele rate to the
stored speed .
• Never rest your foot on the accelerator pedal, especially when
the adaptive cruise control is being u sed because doing so will
override the braking function and prevent the brakes from being
applied by the system when it detect s a situation when the brake s
must be applied.
• Alway s remember that the adaptive cruise control has limits -
it does not react when you drive towards an obstacle or something
else on or near the road that is not moving, such as vehicles
stopped in a traffic jam , a stalled or disabled vehicle .
• Always remember that the adaptive cruise control cannot
detect a veh icle th at i s driving towards you in your traffic lane and
that it cannot detect narrow vehicles such as motorcycles and bicy­
cles .
[ i] Tips
• For safety reasons, the stored speed is deleted when the ignition
is turned off.
• The Electronic Stabilization Program (ESP) and the Ant i-Slip Regu ­
la tio n (A SR) c anno t be de activated when the adaptive cruise cont rol
is sw itched on .
If the ESP and the Anti -S lip Regulation (ASR) has been
de activ at ed an d yo u the n switch on the ad apt ive cruise cont rol, the
ESP fu nction w ill also be activated automatically.
• Dam age cau sed by accide nts (e.g. if the vehicle is dam age d whe n
park ing) can affect the rada r sensor settings. This can cause t he
sys tem to malfunc tion or switch off comple tely.
• The radar sensor cover is heated. In w inter conditions, you should

Driving in traffic
If a vehicle driving ahead is detected, the adaptive cruise control
decelerates (within the limits of the system)=>
page 126, "Driver
intervention prompt" and=>
page 127, "System limitations" to its
speed and after adjusting, tries to mainta in the set distance from the
vehicle ahead. The vehicle may temporarily drive slower than the set
speed wh ile adjusting::::>
& in "Description" on page 116 .
If the vehicle in front accelerates, adaptive cruise control also accel­
erates up to the speed that you have set.
Situation requiring driver intervention
In some situations you will have to use the footbrake to slow the
vehicle down in order to keep a safe distance from vehicle in front of
you o r to avoid a rear-end co llision. In this situation, a symbo l
appears and a warning tone sounds=>
page 126.
Passing another vehicle
If you move into the passing lane and no vehicle is detected ahead,
the adaptive cruise control accelerates to the speed you have set and
maintains it .
Override
You can increase your speed at any time by stepping on the acceler­
ator pedal. After you release the accelerator pedal, the system
adjusts back down to the speed you previously set .
[ i ] Tips
Please note that the amount of acceleration the adaptive cruise
control uses depends on the Distance setting selected. DISTANCE 1
gives you accelerat ion that is dynamic and sporty. DISTANCE 4, on the
other hand, gives more moderate acceleration . For more information
about the time intervals=>
page 121, "H ow is the distance (time
interval) set?".
• Please note that if the adaptive cruise control has begun braking
the vehicle and the driver chooses to brake the vehicle additionally, the brakes may
feel "hard". This is simply due to the pressure build­
up of the initial braking.
• Adaptive cruise contro l is switched off after pressing the foot­
brake. The speed saved up this point can be resumed. To resume the
saved speed, release the brake pedal and pull the control lever
=>
page 120, "Tu rning adaptive cruise control off temporarily". •
