8_ WARNING
-When you leave your vehicle -even if on­
ly briefly -always remove the ignition
key . Th is applies particularly whe n chil­
dren remain in the vehicle . Otherwise the
children could star t the eng ine , release
the par king brake or operate electrical
equipme nt (e.g. power windows). There
is the risk of an accident.
- W hen the veh icle is locked, no one -pa r­
ticularly not children should remain in
the vehicle . Locked doors make it more
difficult for emergency worke rs to get in­
to the vehicle -putting lives at risk .
· Starting from rest
The starting assist function ensures that the
parking broke is rel eased automatically upon
starting.
Stopping and appl ying parking brake

When stopping at a t raffic signal or stopping
in city t raffic on vehicles with an a utomatic
t ransmission, the parking brake can be ap­
plied. The vehicle does not have to be held
with the footbrake . The parking brake elimi­
nates the tendency to creep w ith a dr ive range
engaged. As soon as you drive off as usual,
the parking brake is re leased automat ically
and the vehicle starts to move .
Starting on slop es
When starting on inclines, the starting assist
prevents the vehicle from un in tent ionally roll­
ing back. The braking force of the parking
brake is not released until suffic ient driving
force has been built up at the wheels .

may vary, depending on the type of display in
your vehicle.
The speed is kept constant by modifying en­ gine power or through an active brake inter­
vention.
A WARNING
- Always pay attention to the traffic around you when the cruise control is in
operation . You are always responsib le for
your speed and the distance between
your vehicle and other vehicles.
On th e road 91
-For reasons of safety, cruise control
should not be used in the city, in stop­
and-go traffic, on twisting roads and
when road conditions are poor (such as ice, fog, gravel, heavy ra in and hydro­
plan ing) -risk of accident .
- Turn off the cruise control temporarily when enter ing turn lanes, highway exit
lanes or in construction zones.
- Please note that inadvertently ''resting" your foot on the accelerator pedal causes
the cruise control not to brake. This is
because the cruise control is overridden
by the driver's accelera tion.
- I f a brake system malfunction such as
overhea ting occurs when the cruise con­
trol system is switched on, the braking
function in the system may be switched
off . The other cruise contro l functions re­
main active as long as the indicator light
lij;(i )~14 (US models) ;a (Canad ian mod­
els) is on.
(D Tips
- Vehicles with manual transmission: You
can attain the set speed only if the gear
that is currently engaged will allow it, or
if it does not tax the engine and allows it
to run smoothly . Therefore shift into a
higher or lower gear in a timely manner .
- The brake lights illuminate as soon as
the brakes apply automatically.
Chang ing speed

Audi braking guard
Description
Applies to vehicles: with Audi adaptive cruise control
Fig. 123 Instr ument cluster: approach warning
Braking guard uses a radar sensor. It also
functions within the limits of the system
when adapt ive cruise control is switched off.
What can Audi braking guard do?
When detected in time, the system can assess
situations when a vehicle ahead brakes sud­
denly or if your own vehicle is traveling at a
high speed and approaching a vehicle up
ahead that is moving more slowly. Braking
guard does not react if it cannot detect the
s ituation.
The system advises you of various situations:
- The
distance warning is given if you are too
close to the vehicle ahead for a long time. If
the vehicle ahead brakes sharply, you will
not be able to avoid a collision . The indicator
light . in the display comes on .
- The
approach warning is given when a de­
tected vehicle up ahead in your lane is mov­
ing much more slowly than you are or if it
brakes sharply. When thi s war ning is given,
it may on ly be possible to avoid a co llision
by swerving or brak ing sharp ly. The indicator
light . and indicator in the display will
warn you about the danger
r=.> fig. 123. You
wi ll also hear an acoustic signal.
If you do not react fast enough or do not react
at all to the situation, Braking guard will in­
te rvene by brak ing and the message
