Electromechanical
parking brake
Operation
The electromechanical parking broke replaces
the hand broke.
Fig. 81 Center console: Park ing brake
.. Pull on the switch (®) c::> fig. 81 to apply the
parking brake. The indicator light in the
switch illuminates .
.. Step on the brake pedal or the acce lerator
pedal and press the switch(®) at the same
time to release the parking brake. The indi
cator light in the switch goes out.
Your vehicle is equipped w ith an electrome
chanica l park ing brake. The parking brake is
designed to prevent the vehicle from rolling
un intentionally and rep laces the hand brake.
I n addition to the normal functions of a tradi
tional hand brake, the electromechanica l
parking brake provides various convenience
and safety functions.

- When start ing on inclines, the starting as
sist p revents the vehicle from unintentional
ly rolling back. The braking force of the
parking brake is not re leased until sufficient
driving force has been built up at the
wheels.

An emergency brake ensures that the vehicle
can be slowed down even if the

A WARNING
- When you leave your veh icle -even if on

with you. This applies partic ularly when
c hildren remain in the ve hicle. Otherw ise

Additional information
The engine wi ll switch off in the P, D, N and S
positions as well as in manua l mode . In the P
position, the engine wi ll also remain off if you
take your foot off the brake pedal. The engine
starts again when you select another se lector
lever position and take your foot off the brake
pedal.
If you select the R pos ition during a Stop
phase, the engine will start again.
Shift from D to P quickly to prevent the engine
from start ing unintentionally when shifting
through R.
You can determine for yourself if the engine
will stop or not by reducing or increasing the
amount of force you use to press the brake
pedal. For example, if you only lightly press
on the brake pedal in stop-and and-go traffic
or when turni ng, the engine will not switch off
when the vehicle is stationa ry . As soon as you
press the brake down harder, the engine will
switch off.

not be switched off in the
following situations :
- The engine has not reached the minimum
requ ired temperature for Start-Stop-mode.
- The interior temperat ure se lected by the A/C
system has not been reached.
- The outside temperatu re is extremely high/

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
prox imately 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
a;m
turns off when the speed decreases below the
stored maximum speed.
Sett ing a th resho ld is recommended if you
wou ld 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.
(1} 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.

86 Audi adapti ve cruise control and bra king gu ard
Audi adaptive cruise
control and braking
guard
Introduction
App lies to vehicles: with Audi adaptive cruise co ntrol
The adaptive cruise control system assists the
driver by regu lat ing vehicle speed and helping
to maintain a set distance to the vehicle
ahead, within the limits of the system.
If the
system detects a moving vehicle up ahead,
adaptive cruise control can brake and then ac
celerate your vehicle. This helps to make driv
ing more comfortable both on long highway
stretches and in stop-and-go traffic.
The braking guard system can warn you about
an impending collision and initiate braking
maneuvers
c:::> page 92.
Adaptive cruise control and braking guard
have technical limitations that you must
know, so please read this section carefully, un
derstand how the system works and use them
properly at all times.

Fig. 87 Front of th e veh icle: senso rs and video camera
The areas that conta in the radar and ultrason

c:::> fig. 87
must neve r be cove red by stic kers or other ob

i ce that will interfere with the adaptive cruise
control system and braking guard. For infor
mation on cleaning, refer to
c:::> page 213. The same applies for any modifications made in
the front area.
T he function of the adaptive cru ise contro l
system and braking guard is limited under
some cond itions:
- Objects can only be de tected when they are
w ith in sensor range
c:::> page 88, fig. 90.
- The system has a limited ability to detect
objects that are a short d istance ahead, off
to the side of your vehi cle or mov ing into
your lane.
- Some kinds of ve hicles are hard to detect;
for examp le motorcycles, veh icles with high
ground clearance or overhanging loads may
be detected when it is too late or they may
not be detected at all.
-When driving through curves

& WARNING
A lways pay attention to traffic when adap
tive cruise contro l is switched on and brak
ing g uard is active. As the dr iver, you are
still respons ible for starting and for main
taining speed and distance to other ob
jects. Braking guard is used to assist you .
The dr iver must a lways take action to avo id
a collis ion . The driver is a lways respons ible
fo r braking a t the co rrec t time.
- Imp roper use of adaptive cru ise control
can cause collisions, other acc idents and
serious pe rsonal in jury.
- Never let the comfort and convenience
that adaptive cruise control and braking gua rd offer d istract you from the need to
be alert to traffic condit ions and the
need to rema in in fu ll control of your ve
h icle at a ll times,
- Always remember that the adaptive
cruise control and braking guard have
limits -they will not s low the vehicle
down or maintain the set distance when
you drive towards an obstacle or some
thing on or near the road that is not
mov ing, such as vehicles stopped in a
traffic jam, a stalled o r disabled vehicle.
