this case, park the vehicle on level ground and secure it by placing these­
lector lever in the P position (automatic
transmission). See your authorized Audi dealer or qualified repair facility.
(D Note

-even with the ignition turned
off. To re-
lease the parking brake, the ignition
must be turned on and the brake pedal
must be pressed.
- If driver 's door is opened while the igni­
tion is switched on, the parking brake
sets automatically. This prevents unin­
tended rolling of the vehicle .
- Occasional noises when the parking
brake is set 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 noises associated
with this are normal.

curb if the vehicle starts moving.
& WARNING ~ -
-Always take the vehicle key with you
when leaving the vehicle, even for a short period of time. This applies partic­
ularly when children remain in the vehi­
cle. Otherwise children could start the
engine, release the parking brake or op ­
erate electrical equipment such as power
windows, which increases the risk of an
accident .
- No one should remain in the vehicle
when it is locked, especially children.
Locked doors make it more difficult for
emergency workers to get into the vehi­
cle, which puts lives at risk.

Speed warning system
Introduction
The speed warning system helps you to stay
under a specified maximum speed.
The speed warning system warns you if you
are exceeding the maximum speed that you
have set. You will hear a warning tone when
your speed exceeds the stored value by ap­ proximately 3 mph (3 km/h). An indicator
light . (USA models) . (Canada models) in
the instrument cluster display also turns on at
the same time. The indicator light./.
turns
off when the speed decreases below the
stored maximum speed .
Setting a threshold is recommended if you
would like to be reminded when you reach a
certain maximum speed. Situations where you may want to do so include driving in a country
with a general speed limit or if there is a
specified maximum speed for winter tires .
@ Tips
Even though your vehicle is equipped with
a speed warning system, you should still
watch the speedometer to make sure you
are not driving faster than the speed limit.
Setting the threshold
You can set, change and delete the threshold
in the MMI.
"' Select: Systems or Car systems > Driver as­
sist> Speed warning .
Driving 79
You can set any threshold between 20 mph (30 km/h) and 150 mph (240 km/h). Settings
can each be adjusted in increments of 6 mph
(10 km/h).
Cruise control system
Description
Applies to vehicles: with cruise control system
The cruise control system makes it possible to
drive at a constant speed starting at 15 mph
(20 km/h).
The speed is kept constant by modifying en­
gine power or through an active brake inter­
vention.
.&_ WARNING ~
- Always pay attention to the traffic
around you when the cruise control is in
operation. You are always responsible for
your speed and the distance between
your vehicle and other vehicles.
- 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 a brake system malfunction such as
overheating occurs when the cruise con­
trol system is switched on, the braking
function in the system may be switched
off. The other cruise control functions re­
main active as long as the indicator light
II (US models) !l'I (Canadian models)
ison.

Adaptive cruise control
Description

)
Fig. 73 Detect ion range
What can ad apti ve crui se contr ol do ?
The adaptive cruise contro l system uses radar
and a video camera. The radar is subject to
designated system limits¢
page 82.
On open roads with no traffic, it functions like
a cruise contro l system. The stored speed is
maintained. When approaching an object
ahead and the system detects it, the adapt ive
cru ise control system automatically brakes to
match that object's speed and then maintains
the stored d istance. As soon as the system
does not detect an object ahead, adaptive
cr uise contro l accelerates up to the stored
speed.
Applies to vehicles w ith an automatic trans­
miss ion*: Within the limits of the system,
adap tive cr uise control ca n bra ke in stop-and­
go traffic until t he vehi cle is station ary and
then begin driving again under cer tain condi­
