Speed warning system
Introduction
The sp eed warning system helps you to stay
und er 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 mode ls) in
the instrumen t cluster display also t urns 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 res hold is re commended if yo u
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
specif ied max imum speed for winter tires.
(1} Tips
Even tho ugh your vehicle is equipped with
a speed warning system, you should st ill
watch the speedometer to make sure you are not driving faster than the speed lim it.
Setting the threshold
You can set, change and delete the threshold
in the
MMI.

_& WARNING
=
- Always pay a ttent ion to traffic even when
the cruise control is switched on . You are
always responsib le for your speed and .,.

the distance between your vehicle and
other vehicles.
- For safety reasons, the cruise control
should not be used in the city, in stop­
and-go traff ic, on twisting roads and
when road conditions are poor (such as
ice, fog, grave l, heavy rain and hydro­
planing) -risk of acc ident .
- Turn off the cruise control temporari ly
when entering turn lanes, highway exit lanes or in const ruction zones .
- Please note that inadvertent ly "rest ing"
yo ur foot on the accelerato r peda l causes
the cruise control not to brake. This is
because t he cr uise con trol is overr idden
by the driver's a cce le rat ion.
- If a brake system malfunction such as
overheat ing occurs when the cruise con­
t ro l system is sw itche d on, t he braking
f unction in the system may be switched
off. The other cr uise control f unctions re ­
main active as long as the indicator light
(~j(O~i4 (US models) !Iii (Canad ian mod­
els) is on.
The brake lights illuminate as soon as the brakes decelerate automat ica lly.

Audi adaptive cruise control and braking guard 89
When approaching a moving vehicl e up ahead,
the adaptive cruise contro l system automati­
cally brakes to match that object's speed and
then maintains the stored distance.
If the ve­
hicle ahead accelerates, adaptive cruise con­
trol will also accelerate up to the stored
speed .
The higher the speed, the greater the distance
in yards (meters) ¢.&. . The
Distance 3 setting
is recommended .
The distances prov ided are specified values .
Depending on the driving situation and the
how the vehicle ahead is driving, the actual
distance may be more or less than these tar ­
get distances.

A WARNING
Following other vehicles too closely in­
creases the risk of collisions and serious
personal injur y.
- Setting short distances to the traffic
ahead reduces the time and distance
available to bring your vehicle to a safe
stop and makes it even more necessary
to pay close attention to traffic. -
Always obey applicable traffic laws, use
good judgment, and select a safe follow­
ing d istance for the traff ic, road and
weather conditions .
(D Tips
-Distance 3 is set automatically each time
you switch the ignition on.
- Your standard settings are automatically
stored and assigned to the remote con­
trol key being used.

In certain situations, the system will prompt
yo u to take action . This could happen, for ex­
amp le, if braking by the adaptive cruise con­
trol system is not enough to maintain enough
distance to the veh icle ahead .

Audi braking guard
Descript ion
Applies to vehicles: with Audi adaptive cruise control
Fig. 93 Instrument cluster: approach warn ing
Braking guard uses radar sensors and a video
camera . It also functions within the limits of
the system when adapt ive cruise control is
switched off .
What can 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 . Brak ing
guard does not react if it cannot detect the
situation.
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
I in the display comes on .
- The
approach warning is given when a de­
tected veh icle up ahead in your lane is mov ­
i ng much more slowly than you are or if it
brakes sharply . When this warning is given,
it may only be possible to avoid a collision
by swerving or braking sharply. Th e indicator
light
I and indicato r in the display will warn
you about the danger¢
fig. 93. You will a lso
hear an acoustic signal.
ll This is not ava ilable in some co un tri es .
If you do not react fast enough or do not react
at all to the situation, braking guard will inter·
vene by braking.
- If a coll is ion is imminent, the system will
first provide an
acute warning by briefly and
sharply applying the brakes.
- If you do not react to the acute warning,
braking g uard can brake wit h increas ing
force w ith in the limits of the system . This
reduces the vehicle speed in the event of a
collision.
- The system can initiate maximum braking
short ly before a collision
1l . Full deceleration
at high speeds occurs only in vehicles with
adapt ive cruise control and side assist (pre
sense plus).
- If the braking guard senses that you are not
braking hard enough when a collision is im·
m inent, it can increase the braking force.
- The pre sense functions also engage when a
collision is imminent¢
page 192.
Which functions can be controlled?
You can switch braking guard and the dis­
tance/approach warning on or off in the MMI
¢ page 91, Settings in the MMI.
A WARNING
Lack of attention can cause collisions, oth­
er accidents and serious personal injuries.
The braking guard is an assist system and
cannot prevent a collision by itself. The
driver must always intervene. The driver is
always respons ible for braking at the cor­
rect time.
- Always pay close att ent ion to traffic,
even when the braking guard is switched
on. Be ready to intervene and be ready to
take comp lete control whenever necessa­
ry . Always keep the safe and legal dis­
tance between your vehicle and vehicles up ahead.
- Braking guard works within limits and
will not respond outside the system lim· its, for example when approaching a ..,.

Automatic Transmission
multitronic, S tronic,
tiptronic
Introduction
App lies to vehicles: with multit ro nic/S tronic/t ipt ronic
The automat ic transm iss ion is controlled elec­
tronically . The transmiss ion ups hifts or down­
shifts automatically depend ing o n which drive
p rog ram is se lect ed.
When a
moderate driving style is used, the
tra nsmission selects the most econom ica l
d riving mode .
It will then change up early and
de lay the downshifts to g ive bette r fu el econ­
omy.
The transmission switches to a sporty mode after a k ick- down or when the drive r uses a
sporty driving style ch aracte rized by quick ac­
celerator peda l movements, heavy ac celera­
tion, frequent ch anges in speed and traveling
at the maximum spee d.
I f desired, the drive r can a lso se lect the gears
manually ( tiptronic mode ) ¢ page 111.
Various automat ic transm issions may be in ­
stalled, depend ing o n the mode l:
multitronic transmi ssion
The mult itron ic transm ission is a continuously
variable transmission. Power is transferred us­ i n g a mu ltidisk clutch . In contrast to conven­
tional automat ic transm iss ions using shift ing
ope rations, the transmiss ion ratio in the con­
tinuously va riab le transm iss io n is changed
con tinuously. Th is op timi zes the com fort level
a nd co nserves fuel.
S tronic transmission
The S tronic is a dual -clutch transmission .
P owe r is transfe rred using two clutches that
wo rk ind ependen tly from one a nother. They
r e pl ace the tor qu e conve rter u sed in co nven­
tional a utoma tic transm iss io ns an d allow t he
ve hicl e to accelerate without a no ticeable in ­
ter ruption in traction.

The Automatic Shift Lock only functions when
the vehicle is stationary or at speeds below
1 mph (2 km/h).
At speeds above about 1 mph (2 km/h) the
Automatic Shift Lock is automatically deacti­
vated in the N position.
A time delay element prevents the se lector
l eve r from locking when it is moved thro ugh
the N position (going from R to 0/5). The lock­
ing e lement will lock the selector lever if the
lever is left in N (Neutral) for more than ap­
prox imately 2 second, without the brake ped­
al being pressed.
