more detail. If the driver message Parking brake! appears, there is an
operat ing malfunction in the parking brake which you should have
repaired immediately by an authorized Audi dealer or other qualified
workshop ~
page 28.
[I] Tips
• You can apply the parking brake at any time -even with the igni­
tion turned off. The ig nition must be turned on in order to release the
parking brake.
• Occasional noises when the parking brake is applied and released
are normal and are not a cause for concern.
• When the vehicle is parked, the parking brake goes through a self­
test cycle at regular intervals . Any associated noises are normal. •
Parking
Various rules apply to prevent the parked vehicle from
rolling away accidentally.
Parking
-Stop the vehicle with the foot brake.
- Pull the switch to apply t he parking brake.
- Move the selector lever to P.
- Turn the engine off::::>&.
In addition on inclines and grades
-Turn the steering wheel so that your vehicle will ro ll
against the curb in case it should start to move.
_& WARNING
• When you leave your vehicle -even if only briefly· always
remove the ignition key. This applies particularly when children

ment Safety first
& WARNING
(continued )
remain in the vehicle. Otherwise the children could start the
engine, release the parking brake or operate electrical equipment
(e.g. power windows). There is the risk of an accident.
• When the vehicle is locked, no one -particularly not children
should remain in the vehicle. Locked doors make it more difficult
for emergency workers to get into the vehicle -putting lives at
risk. •
Starting from rest
The starting assist function ensures that the parking
brake is released automatically upon starting.
Stopping and applying parking brake
-Pull the switch to apply the parking brake.
Starting and automatically releasing the
parking brake
- When you start to drive as usual, the parking brake is auto -
matically released and your vehicle begins to move.
Whe n stopping at a tra ffic signal or stopping in city traffic on ve hicles
with an automatic transmission, the parking brake can be applied.
Th e vehicle does not have to be held with the footbrake. The parking
brake eliminates the tendency to creep with a drive range engaged.
As soon as you drive off as usual, the parking brake is released auto­
matically and the vehicle starts to move.
Starting on slopes
When starting on inclines, the starting assist prevents the vehicle
from unintentionally rolling back. The braking force of the parking
brake is not released until sufficient driving force has been built up at
the whee ls. ..,

(I] Tips
For s afety reasons, t he pa rking br ake is r eleased automatically only
when the driver 's safety belt is engaged in the buck le .•
Starting off with a trailer
To prevent rolling back unintenti onally on an incline, do
the following :
-Keep the switch pu lled and depress the accelerator. T he
parking brake stays a pp lied and prevents the vehic le from
ro lling backward.
- You can re lease the switch once you are sure tha t you are
deve lopi ng enough driving force at t he wheels by
depressing the accelerator .
Depending on the we ight of the rig (vehicle and trailer) and the
sever ity o f the in cl ine, you may roll backwa rds as you start . You can
prevent roll ing backwards by holding the park ing brake sw itch pulled
out and accele ra ting -just as you wou ld when starting on a hill wi th a
conventional hand brake .•
Emergency braking
In the event that the conventional brake system fails or
locks .
-In an emergen cy , pull t he sw itch and contin ue to pull it to
slow your vehic le down with t he p arking brake.
- As soon as you re lease t he swi tch or acce lerate, the
bra king process s tops.
If you pull the switch and hold it above a speed of about 5 mph (8
km/h), the emergency braking fu nction is initiated . The vehicle is braked at all four wheels by activating the
hydraulic brake system.
Th e b rake pe rformance is s imila r to mak ing an eme rge ncy sto p .=>
&
In order not to act ivate the emergency brak ing by m istake, an audib le
warning tone (buzzer) sounds when the switch is pulled. As soon as
t he swi tch is re leased, or the acce lerator pedal is dep ressed , emer ­
gency braking stops .
& WARNING
Emergency braking should only be used in an eme rgency , when
the normal foot brake has failed or the brake pedal is obstructed .
Using the parking brake to perform emergency braking will slow
your vehicle down as if you had made a full brake application . The
laws of physics cannot be suspended e ven with ESP and its associ ·
at ed components (ABS, ASR, EDS ). In corners and when road or
weather conditions are bad , a full brake application can cause the
vehicle to skid or the rear end to break away· ri sking an accid ent. •

Adaptive cruise control
Speed and distance control system
Applies to veh icl es : w it h adaptive c ruise contro l
Description
The adaptive cruise control driver assistan ce program is a
combined speed and distance control system .
Fig. 113 Front
bum per : Po sitio n of
ra dar sen sor
Any speed betwee n about 20 mph (30 km/h) and about 95 mph
( 1 50 km/ h) can be set and held with the adaptive cruise control. The
system also regu lates a pre-set distance from the vehicle ahead
w ith in the limits of the system described.
Driv ing c an be more relaxed, particularly o n long tr ips on inter states
or on other highways that a re generally straig ht.
How does it work?
Yo u ca n operate the adaptive c ruise contro l using the leve r o n the
steer ing wheel column:::,
page 119, "H ow is the speed sto red? " and
=:> pag e 121, "How is the distance (time interval) set?".
Driver information
Important info rmation is brought up in the speedometer and in the
instrumen t cluster dis play as the ve hicl e is be ing driven :::,
page 122,
"Driver in format ion ".
What is important for you to know
The adaptive cru ise cont rol is set with system-specified lim its, that is,
a s a driver, yo u will h ave to adju st the speed and dist an ce to the
vehicle ahead in some instances :::,
page 126, "Driver inte rvention
promp t" and =>
page 127, "Sy stem limi ta tions ".
& WARNING
Improper u se of the adaptive cruise control can cause colli sion s,
othe r accidents and serious personal injury.
• Never drive at speeds that are too high for traffic, road and
weather condition s.
• Never follow the vehicle in front so closely that you cannot stop
your vehicle safel y. The adaptive cruise control cannot brake the
vehicle safely when you follow another vehicle too closely . Alway s
remember that the adapti ve cruise control has a braking power
that i s only about 25% of the vehicle 's maximum br aking ability,
the automatic b rak ing function cannot bring the vehicle to a stop.
• Never use adaptive cruise control on roads where you cannot
drive safely at a steady speed , including city , stop-and-go or heavy
traffi c, on winding road s or when road cond ition s are poor (for
e x ample , on ice, gravel, in fog, heavy rain or on wet roads that
in crea se the risk of hydroplaning).
• The rada r sensor' s
vis io n can be reduced by rain, snow and
heavy spray . This can re sult in vehicle s driving ahead being inade­
qu ately detected or, in some circumstances , not detected at all. If
necessary, t ake action yourself! ..,

____________________________________________ A_ d_ a.._p _t_ i_ v _e_ c_r_u _ i_ s _e_ c_o_ n_ t_r _o _l __ ffl'II
& 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
st ill ch eck befor e dr iv in g to make s ure i t is free of ice and s now. If
necessary, clean the area nea r the rada r sensor carefully=>

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". •
