Setting the distance and driving
program
App lies to vehicles: with adaptive cruise control
Fig. 89 Opera ting lever: set ting the distance
The distance at which the adaptive cruise con­
trol fo llows a vehicle in front is determined by
time intervals. A time interval to a vehicle in
front is established and maintained. This pro­
duces a speed-dependent interval. The higher
the speed, the greater the safety interval in
yards (meters)

Setting the distance
• Tap the switch to disp lay the current set dis­
tance

Setting the distance
When approaching a moving vehicle up ahead,
the adaptive cruise control system automati­
cally brakes to match that object's speed and
then maintains the stored distance. When this
happens , the actual d istance may briefly be
less than the stored distance.
If the vehicle
ahead accele rates, adaptive cruise control will
also accelerate up to the stored speed. T
he higher the speed, the g reate r the distance
in yards (meters)

is recommended.
T he distances provided are specified va lues .
Depending on the driving situation and the
how the vehicle ahead is driving, the actua l
distance may be more or less than these tar­
get distances .

Setting the driving program
You can select Dynamic , Standard or Comfort
driving programs. Depending on the selected
driving program and distance, driving behav ­
ior when accelerating wi ll vary from dynamic
to comfortab le.
A WARNING
Following other vehicles too closely in­
creases the risk of collis ions and ser ious
personal injury .
- Sett ing short distances to the traffic
ahead reduces the time and distance
availab le 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 distance for the traffic, road and
weather conditions.

Audi braking guard
Descript ion
Applies to vehicles: with adaptive cruise contro l
Fig. 90 Instrument cluster: approach warning
Audi braking guard uses radar sensors and a
video camera. It is active at speeds above
about 6.2 mph (10 km/h) and also works
within system limits when adaptive c ruise
control is switched off.
On vehicles w ith adaptive cru ise control and
Audi side assist (Aud i pre sense plus), system
functions also engage when a collision is im­
minent
c::> page 182.
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 veh icle is traveling at a
h igh speed and approaching a veh icle up
ahead that is moving more slowly . Audi brak­
in g guard does not react if it cannot detect
the situation.
The system advises you of various s ituations:
- 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 coll is ion . The ind icator
light
I in the disp lay comes on. Take imme- diate action to avoid
the collision and in­
crease the distance to the vehicle up ahead.
- The
approach warning is given when a de­
tected vehicle up ahead in your lane is mov­
ing much more slowly that you are or if it
brakes sharp ly. When this warning is given,
it may only be possible to avoid a collision
by swerving or braking sharply. The indicator
light
I and the symbol in the display will
warn you about the danger
c::> fig . 90 . You
w il l also hear an acoustic signal.
If you do not react fast enough or do not react
at all to the situation, Audi braking guard w ill
intervene by braking and the message
braking
guard intervention
will appear.
- If a collision is imminent, the system will
first provide an
acute warning by braking
sharply.
- If you do not react to the acute warning, Au­
di braking guard will brake w ith increased
force in severa l stages to reduce the speed
in a poss ible collis ion. On veh icles with
adaptive cruise control and Audi side assist
(Audi pre sense plus), the system can brake
with increasing force up to maximum dece l­
eration shortly before a sensed collision
c::>page 182.
-If the Audi braking guard senses that you
are not brak ing hard enough when a colli­
sion is imminent, it can increase the braking
force.
Audi braking guard takes the driver's reaction
time into consideration in order to provide
timely warnings. The system reaction time de­
creases automatically in some situations, for
example when it detects acce lerator pedal use
or steering input . The Audi braking guard in­
tervent ion stops in certa in situations, for ex­
amp le if you press the accelerato r pedal to
pass the vehicle moving ahead of you in your
lane .
Which functions can be controlled?
You can switch Audi braking guard and the
distance/approach warning on or
off i n the
MM I ¢ page 86, Settings in the MMI.

& WARNING
The Audi braking guard is an assist system
and cannot prevent a collision by itself.
The driver must always intervene . The driv­
er is always responsible for braking at the
correct time.
- Always pay close attention to traffic, even when the Audi braking guard is
switched on. Be ready to intervene and
be ready to take comp lete control when­
ever necessary. Always keep the safe and
legal distance between your vehicle and
vehicles up ahead.
- Audi braking guard works within limits
and w ill not respond outs ide the system
limits, for examp le when approaching a
stopped vehicle or stationary obstacle
(end of a traffic jam or vehicle that has
broken down in traffic).
- Always remember that the radar sensor
for the Audi braking guard works only
within defined detection and range limits
that may prevent the proper detection of
other vehicles.
- The radar sensor's function and range
can be reduced by rain, snow and heavy
spray. moving vehicles up ahead may not
be promptly detected or may not be de­
tected at all.
- Reflective surfaces includ ing crash barr i­
ers or tunnel entrances may impair the
function of the radar sensor .
(D Tips
Lack of attention can cause coll is ions, oth­
er accidents and ser ious personal injuries.
- You can stop the Audi braking guard in- tervention w ith increas ing braking force
by applying the brakes yourself or by ac­
celerat ing rapidly .

Before you move the selector lever from the P
posit ion, you must always apply the brake
peda l before and while depressing the button
in the handle of the selector lever.
_&. WARNING
- Unintended vehicle movement can cause
serious injury .
- When the selector lever is in a driving
pos ition, the vehicle may creep, even at
idle speed. Therefore do not release
the parking brake or foot brake unti l
you are ready to move, because power
is transmitted to the wheels as soon as
a driving position is engaged.
- Do not accelerate while selecting a
driving position. At this time the en­
gine must be at idle speed so that un­
due stress is not placed on the clutches
in the transmission .
- Remember: Even when stopped briefly with the automatic transmission in D/S
or R, engine power is being transmit·
ted to the wheels. Your veh icle cou ld

"creep" forward or backward. When
stopped, keep the brake pedal fully de­
pressed and use the park ing brake if
necessary to keep the veh icle from roll­
ing.
- If the selector lever is unintentionally
moved into N wh ile you are driving, take
your foot off the accele rator pedal and
wait for the engine to return to idle speed before selecting a d riving position.
- Never shift into R or P when the vehicle is in motion.
- Never get out of the driver's seat when
the engine is running.
- If you must get out of the vehicle, move
the se lector lever securely into the P po­
sit ion and apply the par king brake firm ly.
- If the engine must remain running , never
have any driv ing position engaged when
chec king under the hood. Make sure the
selector lever has securely engaged and is locked in P with the parking bra ke
firmly set ¢

prod uce maximum vehicle acce leration as
l ong as you continue to press the accelerator
pedal beyond this resistance point.
A WARNING
Be careful when using the k ick-down fea­
ture o n slippe ry roads . Rapid accelerat ion
may cause the veh icle to skid .
Dynamic shift program (DSP}
Applies to vehicles: with tiptronic
The au tomatic transmission is electronically

selec t the best shift progr am suit­
ed to the driving condit ions and driving style .
T he transmission will se lect one of the
econo­
m y
programs when you drive at a steady
speed or a gradually changing speed without heavy acceleration . T his achieves optimum
fuel efficiency, with early upshifting and de­ layed downshifting .
The transmission will automat ically select the
s porty shift programs when you drive at high­
e r speeds, or with heavy acceleration and fre­
quent ly chang ing speeds . Upshifts are de layed
to make fu ll use of eng ine power. Downsh ift­
i ng takes p lace a t higher engine speeds than
i n the e conomy programs.
The selection of the most su itab le shift p ro­
g ram is a cont inuous, automatic p rocess. The
d river can al so make the transmission switch
to a sporty program by
quickl y pressing down
the gas pedal.
This causes the transmission to shift down to
a lower gear to achieve rap id acceler ation, e.g.
fo r q ui ckly passing another veh icle. You do not
need to press the gas peda l into the kick -down
range . After the transmission has upshifted,
the original program is se lected according to
your driving style.

An additional sh ift program allows the auto­
matic transmission to select the p roper gear
for uphill and downhi ll grad ients.
T his keeps the transm ission from shift ing up
