A WARNING
- USA models: If the 1111 warning l ight
and
the m warning light come on to ­
gether, the rear wheels could lock up
first under hard braking . Rear wheel lock ­
up can cause loss of vehicle control and
an acc ident. Have your vehicle repaired
immediately by your authorized Audi
dealer or a qualified workshop . Dr ive
slowly and avoid sudden, hard brake ap·
plicat ions.
- Canada models: If the brake warn ing
light . and the ABS warning light

.
lock up first under hard braking . Rear
wheel lock-up can cause loss of vehicle
control and an accident . Have your vehi­
cle repaired immed iately by your author·
ized Audi dealer or a qualified workshop .
Drive s low ly and avoid sudden, hard
brake applications.
- If the brake warning/ind icator light does
not go ou t after a few seconds and the
pa rking brake released, or lights up wh ile
you are driv ing, the fluid level in the
brake fluid reservoir is too low. If yo u be ­
lieve that it is safe to do so, proceed im­
mediately at low speed to the nearest
author ized Audi dealer or qualif ied repair
facility and have the brake system in·
spected.
- Always keep in mind that after severa l
brake applications, you will need greater
pressure on the brake pedal to stop your
veh icle. Do not rely on strained brakes to
respond with max imum stopping power
in critical s ituations. You must allow fo r
increased braking dis tances. The extra
distance used up by fading brakes could
lead to an accident.

driving by automatically releasing the park ­
ing brake ¢
page 98, Starting from rest.
-When starting on inclines, the starting as­
sist prevents the vehicle from unintentional­
l y rolling back. The braking force of the
parking brake is not released until sufficient
driv ing force has been built up at the
wheels .

(D Tips
-You can apply the parking brake at any
time -even with the ign ition turned off.
The ignit ion must be turned on in order
to release the par king b rake .
- Occasional noises when the parking
brake is applied and released are normal
and are not a cause fo r conce rn.
- When the vehicle is parked, the park ing
brake goes throug h a self-test cycle at
regu lar inte rva ls. Any associated noises
are normal.
Parking
Various rules apply to prevent the parked ve­
hicle from rolling away accidentally.
Parking
"' Stop the vehicle with t he foot brake .
"' Pull the switch to apply the parking brake.
"' Automatic transmission*: Move the selector
lever to
P .
"' Tur n the engine off¢_&.
"' Ma nual transmiss ion: Shift into 1s t gear.

start to move.
A WARNING
- When you leave you r vehicle -even i f on­
ly briefly -always remove t he ignition
key. This app lies pa rticularly when chil­
dren remain in the vehicle. Otherwise t he
children could start the eng ine, release
the park ing brake or operate electrical

102 Adapti ve crui se control
Adaptive cruise control
Speed and distance
control system
Description
Applies to vehicles: with Audi adaptive cruise co ntrol
The adaptive cruise control driver assistance
program is a combined speed and distance
control system.
F ig. 110 Front bumper: Positio n of radar sensor
Any speed between about 20 mph (30 km/h)
and about 95 mph (150 km/h) can be set and
held with the adaptive cruise control. The sys­
tem also regulates a pre -set distance from the
vehicle ahead within the limits of the system described.
Driving can be more relaxed, particularly on
long trips on interstates or on other highways
that a re generally straight .
H ow do es it work?
You can operate the adaptive cruise contro l
using the lever on the steering wheel column
c::> page 104, How is the speed stored? and
c::> page 106, How is the distance (time inter ­
val) set? .
Driver inform ation
Important information is brought up in the
speedometer and in the instrument cluster
d isplay as the vehicle is being driven
c:::, page 107, Driver information .
What is imp orta nt fo r you to kn ow
The adaptive cruise control is set with system­
specified limits, that is, as a driver, you will have to adjust the speed and distance to the vehicle ahead in some instances
c:::,
page 111,
Driver intervention prompt
and c::, page 112,
System limitations.
A WARNING
--
Improper use of the adaptive cruise con­
trol can cause collisions, other accidents
and serious personal injury.
- Never drive at speeds that are too high
for traffic, road and weather conditions.
- Never follow the vehicle in front so close­ ly that you cannot stop your veh icle safe­
ly . The adaptive cruise control cannot
brake the vehicle safely when you follow
another vehicle too closely. Always re­
member that the adaptive cruise control
has a braking powe r that is only about
25% of the veh icle's maximum braking
abi lity, the automatic braking 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 traffic, on winding roads or
when road cond it ions are poor (for exam­
p le, on ice, gravel, in fog, heavy rain or
on wet roads that increase the risk of hy­
d rop laning) .
- The radar sensor 's
vision can be reduced
by rain, snow and heavy spray. This can
resu lt in veh icles dr iving ahead be ing in­
adequately detected or, in some circum­
stances, not detected at a ll.
If necessary,
t ake action yourself!
- Always turn off adap tive c ruise control
when en ter ing turn la nes, highway exit
lanes and construction zones or similar
situations beca use the vehicle will a uto­
mat ically acce le rate to the stored speed.
- Never rest your foot on the accelerator pedal, especially when t he adaptive
cruise contro l is being used because do­
ing so will override the braking function
and prevent the brakes from being ap­ plied by the system when it detects a sit­
uation when the brakes must be applied.
- Always remember that the adaptive
cru ise contro l has limits -it does not

104 Adapti ve crui se control
keep a safe distance from vehicle in front of
you or to avoid a rear-end collision . In this sit­
uation, a symbol appears and a warning tone
sounds
¢ page 111.
Passi ng anoth er vehicl e
If you move into the passi ng lane and no veh i­
cle is detected ahead, the adaptive cruise con­
trol accelerates to the speed you have set and maintains it.
Overrid e
You can increase your speed at any t ime by
stepp ing on the acce lerator pedal. After yo u
re lease the accelerator pedal, the system ad­
justs back down to the speed you previously set .
@ Tips
Please note that the amount of accelera­
tion the adaptive cruise control uses de­ pends on the Distance setting selected.
DISTANCE 1 gives you accelerat ion that is
dynamic and sporty . DISTANCE 4, o n the
other hand, g ives more moderate accelera­
tion . For more information about the time
intervals ¢
page 106, How 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 vehi­
cle add itionally, the brakes may fee l
"hard" . This is simply due to the pressure
build- up of the initial braking.
- Adaptive cruise control is sw itched off af ­
ter pressing the footbrake . The speed
saved up this point can be resumed. To resume the saved speed, release the
brake pedal and pull the control lever
