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 ••
turns off when the speed decreases below the
stored maximum speed.
Sett ing a thresho ld is recommended if you
wou ld like to be reminded when you reach a
cer tain maximum speed. Situations where you
may want to do so include driving in a country
On the road 91
with a general speed limit or if there is a
specified max imum speed for winter tires .
@ Tips
Even though your vehicle is eq uipp ed w ith
a speed warning system, you should still
watch the speedometer to make sure you
are not dr iv ing faster than the speed limit.
Setting the threshold
You can set, change and delete the threshold
in the MMI.
.. Select: !CAR I function button> Car systems
cont rol button > Driver assist > Speed warn·
ing .
You can set any threshold between 20 mph

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¢
page 100.
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. 93 Front of th e veh icle: senso rs and video camera
The areas that conta in the radar and ultrason­
ic sensors and the v ideo camera ¢
fig. 93
must never be covered by stic kers or other ob­
jects or obstructed w ith dirt, insects, snow or
i ce that will interfere with the adaptive cruise
control system and braking guard. For infor­
mation on cleaning, refer to¢
page 216. 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¢
page 96, fig. 96.
- 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

-Stat ionary objec ts ¢page 95.
& 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
for 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.

also responds to the driving behavior of the
veh icle ahead in a more conservative or sporty
manner.
Engine sound*
The sound of the engine is adapted to the se­
l ected mode and ranges from subtle to sporty.
(D Note
- Make sure there is enough clearance
above and below the vehicle when park­
i ng. The height of the vehicle can change
once it is parked due to temperature
fluctuations, changes to the load cond i­
tions and changes to the dr iv ing modes,
which can affect clearance.
- When transporting the veh icle on a car
carrier, tra in, ship or by other means, on­
ly tie the veh icle down at the running
surface of the tires, which is the outer
circumference. Secur ing the vehicle at
the axle components, s uspension struts
or towing eyes is not permitted because
the pressure in the air suspension struts
can change during transport . The vehicle
may not be sec ured s ufficient ly if this
happens.
- If you are going to tow a trailer, you
must activate the trailer operation mode
C? poge 212.
@ Tips
- In some models, the maximum vehicle
speed can only be reached in the
auto
and dynamic modes.
- Selecting the
dynamic mode results in
sporty shifting characteristics . The S
gear position engages automatically.
- In vehicles that have dynamic steering*,
operating noise is heard when starting or
stopping the engine. Th is does not indi­
cate a problem.

Universal remote
control
General information
Applies to vehicles: with Home link unive rsal remote con­
tro l
The Homelink universal remote control can
be programmed with hand -held transmitters
from existing equipment
Using the Homelink universal remote control,
you can operate equ ipment such as garage
doors, property gates and house lights from inside your vehicle .
Using the Homelink universal remote control,
you can replace up to three separate hand ­
held transmitters for equipment on your
property with just one universal remote con­
trol. Most of these transmitters a re used to
operate ga rage doors and property gates. The
individual transmitters are programmed at
the front bumper. That is where the control
module is located.
The transmitters must be programmed first in
order to operate systems using the Homelink
universal remote control.
A WARNING , .,.
- Never use the Homelink transmitter
with any garage door opener that does
have not the safety stop and reverse fea­
ture as required by federal safety stand­
ards . Th is includes any garage door open ­
er model manufactured before April 1,
1982.
- A garage door opener which cannot de­
tect an object, signaling the door to stop
and reverse does not meet current feder­
al safety standards . Us ing a garage door
opener without these features increases
risk of serious injury or death.
- For safety reasons never release the
parking brake or start the engine while
anyone is standing in front of the vehicle .
- A garage door or an estate gate may sometimes be set in motion when the
