Audi dealer or authorized Audi Service Facili­
ty. If you can release the parking brake and
the message still appears, see an authorized
Audi dealer or authorized Audi Service Facili­
ty immediately to have the malfunction cor­
rected.
- If the indicator light and message appear
while driving, the hill start assist or emer­

-Follow the warnings on c::;, page 217,
Working in the engine compartment
be­
fore opening the hood and checking the

engine, release the pa rking brake o r op ­
erate electrical equipment such as power
windows, which increases the risk of an

84 Driving
-For reasons of safety, cruise control
should not be used in the city, in stop­
and-go traffic, on winding roads and
when road conditions are poor (such as
ice, fog, gravel, heavy rain and hydro­
planing) -you could have an accident .
- Switch the cruise control off temporarily
when driving in turning lanes, highway
exits or in construction zones.
- Please note that unconsciously "resting"
your foot on the accelerator pedal pre­
vents the cruise control from braking.
This is due to the control system being
overridden by the driver's acceleration.
- If there is a brake system malfunction
such as overheating when the speed
warning system is switched on, the brak­
ing function in the system will be deacti­
vated. The remaining speed warning sys­
tem functions will remain active, as long
as the
B (USA models)/ ii (Canada
models) indicator light is on.
@ Tips
- The cruise control system is ideal for
stretches with speed limits. The driver is
responsible for adhering to the correct
speed.
- The cruise control remains active when
shifting gears.
- The brake lights turn on when the brakes
are activated.

Overriding the speed
You can press the accelerator pedal down to
increase your speed, for example if you want
to pass someone. The speed you saved earlier
will resume as soon as you release the acceler­ ator pedal.
If, however, you exceed your saved speed by 5
mph (10 km/h) for longer than 6 minutes, the
cruise control turns off temporarily. The
II
(USA models) / Bl (Canada models) indicator
light in the instrument cluster turns off and
the stored speed is retained .

-When approaching stationary objects
such as stopped traffic, adaptive cruise
control will not respond and pre sense
front will have limited function.
- The adaptive cruise control system and
pre sense front do not react to people,
animals, objects crossing the road or on­
coming objects.
- The function of the radar sensors can be
affected by reflective objects such as
guard rails, the entrance to a tunnel,
heavy rain or ice.
- Never follow a vehicle so closely that you
cannot stop your vehicle safely. The
adaptive cruise control cannot slow or
brake the vehicle safely when you follow
another vehicle too closely. Always re­
member that the automatic braking
function cannot bring the vehicle to a
sudden or emergency stop under these
conditions.
- To prevent unintended operation, always
switch ACC off when it is not being used.
(D Note
The sensor can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. The adaptive cruise control
and pre sense front may become impaired
as a result. Have an authorized Audi dealer
or authorized Audi Service Facility check
their function.
In curves
Applies to vehicles: with Audi adaptive cruise control and
Audi pre se nse front
Fig. 76 Example: driv ing into a curve
Audi adaptive crui se control 87
When driving into a curve q fig. 76 and out of
a curve, the adaptive cruise control may react
to an object in the neighboring lane and apply
the brakes. You can prevent that by pressing
the accelerator pedal briefly.
Stationary objects
Applies to vehicles: with Audi adaptive cruise control and
Aud i pre sense front
Fig. 77 Example : object changing lanes and stat ionary

Adaptive cruise control
The adaptive cruise control system only reacts
to objects that are moving or that the system
has already detected as moving. For example,
if a detected vehicle @turns or changes
lanes, the adaptive cruise control will not re­
act to a stopped vehicle@. Press the brake
pedal to slow your vehicle down .
Pre sense front
Pre sense front only reacts to stationary ob­
jects at low speeds.

On ope n roads w ith no t raff ic, i t fun ctions like
a cruise co ntro l system . Th e stored s peed is
main taine d. When approach ing an object
ahead and the system detects it, the ada ptive
cr uise control system automatically brakes to
match that ob ject's speed and then maintains
the stored d istance. As soon as the system
does not detect an object ahead, adaptive
cru ise control accelerates up to the s to red
speed .
W ith in the lim its of the system, adaptive
cru ise contro l can brake in stop-and-go traff ic
u ntil t he vehicle is stationary and then begin

Which functions can be controlled?
When you sw itch adaptive cruise cont ro l on,
you can set the cur rent speed as the "control
