Ignition k ey sa fe ty int erlock
The key cannot be removed from the ignition
un less the se lector lever is in the P park posi­
tion . When the ign ition key is removed, the
selector lever will be locked in the P pos ition.
Kick-down
App lies to vehicles: with multitronic or tiptro nic
The kick-down features allows maximum ve­
hicle acceleration.
Appli es to v eh icl es with a multit ronic ®
t ran sm ission
When you depress the acce lerator pedal be ­
yond the resistance point, the transmission downshifts into a lower gear ratio depending
on the vehicle speed and engine speed . As
long as the accelerator pedal is depressed, the
engine speed is automat ica lly regulated for
max imum ac celeration.
Applie s to veh icles with a tiptronic
transmission
When you depress the accelerator pedal be­
yond the resistance po int, the automat ic
transmission downshifts into a lower gear, de­
pending on vehicle speed and engine speed .
The upshift into the next higher gear takes
p lace once the maxim um specified engine
speed is reached.
_&. WARNING
Please note that the drive whee ls can spin
if kick-down is used on a smooth slippery
road -there is a risk of skidding.
Tran sm iss ion 87
Dynamic shift program (DSP)
App lies to vehicles: wit h m ultitro nic or t iptronic
The automatic transmission is electronically
controlled .
The transm iss ion is self adapting and will
a u­
tomati call y select the best sh ift program suit­
ed to the driving conditions and driv ing style.
The transmission wi ll select one of the
eco no­
m y
programs when you drive at a steady
speed or a gradually changing speed w ithout
heavy acceleration . This achieves optimum
fuel eff iciency, with early upshifting and de­
l ayed downshift ing .
The transm iss ion w ill automatically select the
sporty sh ift programs w hen you drive at high ­
er speeds, or with heavy acceleration and fre­ quently changing speeds. Upsh ifts are delayed
to make full use of e ngine power. Downshift­
ing takes place at highe r engine speeds than
in the economy programs .
T he selection of the most suitable sh ift pro­
gram is a continuous, automatic process . The
drive r can a lso make the transm iss ion sw itch
to a sporty program by
quickl y pressing down
the gas pedal.
T h is causes the t ransm ission to shift down to
a lowe r gear to ach ieve rapid acce le rat ion, e.g.
f or quickly passing another vehicle . You do not
need to press the gas pedal into the kick-down
range . After the transmission has upshifted,
the or iginal program is selected according to
your driving style .
Vehicles with mult itronic t ransmission: when
driving on hills and mountains, the gear ratio
continuously adapts to the grade . The trans­
mission downshifts automatically when driv­
ing downh ill if the brake pedal is pressed . As a
result, the engine braking effect inc reases.
Vehicles with tiptron ic transm issions: when
driv ing on hills and mountains, the gear se lec­
tion adapts to the grade. This prevents con­
stant upshift ing and downsh ifting when driv ­
i ng uphill.

A WARNING
-Never leave your vehicle with the engine
running while in gear. If you must leave
your veh icle when the engine is running,
activate the pa rking brake and move the
selecto r lever to P .
- Powe r is still transmitted to the w heels
when the engine is runn ing at idle. To
p revent the vehicle from "c reeping", you
m ust keep your foot on the brake when
the engine is running and the selector
lever is in D/S or R or "t iptronic" mode is
selected.
- Do not press the accelerator pedal when changing the se lector lever position
while the veh icle is stationary and the
engine is running.
- Never sh ift into R or
P while driving .
- Before driving down a steep s lope, re-
duce your speed and shift into a lower
gear with "tiptronic".
- Do not ride the brakes o r press the bra ke
pedal too often or too long. Constant
brak ing ca uses the brakes to overheat
and substantially reduces braking per­
formance, increases braking d istance or
causes complete failure of the brake sys­
tem.
- To preve nt the vehicle from ro lling back
when stopp ing on inclines, always hold it
in place with the b rake pedal or parking
b rake.
- Never hold the vehicle on an incline with
a slipping clutc h. T he clutch opens auto­
mat ica lly when it becomes too hot from

ed .
(D Note
-When s topping on an incl ine, do no t try
to hold t he vehicle in place by pressing
the acce lerator pedal while a driving gear
is se lected. This can cause the S t ron ic
transm ission to overheat and can dam­
age it. Activate t he parking brake or

press the brake pedal to prevent the ve ­
hicle from rolling .
- Allow ing the ve hicl e to roll when the en­
gine is stopped and the selector lever is i n N will dama ge the S tronic transm is­

When acce lerating, the transmiss ion will au­
tomatically shift into the next gear before the
engine reaches its maximum RPM.
I f you apply a ligh t throttle when accelerat­
ing, tiptronic will automatically shift from 1st
to 2nd gear to save fuel. If you app ly a heavy
thrott le, the transmission will stay in 1st gear
unti l near maximum RPM is reached, or unt il
the dr iver shifts into 2nd gear.
If you take your foot off the accelerator peda l
when dr iving down a steep incline, tiptronic
will downshift from the selected gear into the next lower gear until it reaches 1st gear,
based on road speed and eng ine RPM . Auto ­
mat ic downshifti ng is interrupted as soon as
you apply the th rottle aga in .
(D} Tips
- When you sh ift into the next lower gear,
the transmiss ion will downshift only
when there is no possibility of over-rev­
v ing the engine.
- When the kick-down comes on, the
transmission will sh ift down to a lower
gear, depending on vehicle and engine
speeds.
- Tiptronic is inope rat ive when the t rans­
mission is in the fail-sa fe mode.
Kick-down
A pp lies to vehicles: with S tro nic tr ansmiss ion
Kick-down enables maximum acceleration.
When you press the acce lerator pedal down
beyond the resistance po int, the automatic
transmission downshifts into a lower gear, de­
pending on vehicle speed and engine RP M.
It
shifts up into the next h igher ge ar once the
max imum specified engine RPM is reached.
& WARNING
Please note that the wheels could spin on
slick or slippery roads when kick-down is
active.

Audi adaptive cruise control and braking guard 97
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 lating 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 he lps to make driv­
ing more comfortable on long highway
stretches.
The braking guard system can warn you about
an impending collision and initiate braking
maneuvers ¢
page 103.
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.
General information
General information
Applies to vehicles: with Audi adaptive cruise control
Fig. 96 Front of the veh icle: Pos ition of radar sensor
The area that contains the radar sensor
¢
fig. 96 must never be covered by st ickers or
other objects or obstructed with dirt, insects,
snow or ice that will interfere with the adap­
tive cruise control system and Audi braking
guard. For information on cleaning, refer to
¢
page 201. The same applies for any modifi­
cations made in the front area . The
function of the adaptive cruise contro l
system and braking guard is limited under
some cond itions:
- Objects can only be detected when they are
within sensor range
¢page 99, fig . 99.
-The system has a limited ability to detect
objects that are a short distance ahead, off
to the side of your vehicle or moving into
your lane.
- Some kinds of vehicles are hard to detect;
for examp le motorcycles, vehicles 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¢
page 98.
-Stationary objects¢ page 98.
A WARNING
-Always pay attention to traffic when adap-
tive cruise control is switched on and brak­ ing guard is active. As the dr iver, you are
still responsible for starting and for ma in­
tain ing speed and distance to other ob­
jects. Braking guard is used to assist you.
The driver must always take action to avoid
a collision. The driver is always responsible
for braking at the correct time.
- Improper use of adaptive cruise con trol
can caus e collisions, other accidents and
serious personal injury .
- Never let the comfort and convenience
that adaptive cruise control and Audi
braking guard offer distract you from the
need to be alert to traff ic conditions and
the need to remain in full control of yo ur
veh icle at a ll times,
- Always remember that the adaptive
cru ise contro l and Aud i brak ing guard
have lim its -they will not slow the vehi­
cle down or maintain the set d istance
when you drive towards an obstacle o r
someth ing on or nea r the road that is not
moving, such as vehicles stopped in a
traffic jam, a stalled or disabled vehicle.
If registered by the radar sensor, vehicles
or obstacles that are not moving can
trigger a collision warning and if .,.

98 Audi adaptive cruise control and braking guard
confirmed by the video camera, an acute
collision warning.
- For safety reasons, do not use adaptive
cruise control when driving on roads with
many curves, when the road surface is in
poor condition and/or in bad weather
(such as ice, fog, gravel, heavy rain and
hydroplaning). Using the system under
these conditions could result in a colli­
sion.
- Switch adaptive cruise control off tempo­
rarily when driving in turning lanes, on
expressway exits or in construction
zones. This prevents the vehicle from ac­
celerating to the set speed when in these
situations.
- The adaptive cruise control system will
not brake by itself if you put your foot on
the accelerator pedal. Doing so can over­
ride the speed and distance regulation.
- When approaching stationary objects
such as stopped traffic, adaptive cruise
control will not respond and braking
guard will have limited function.
- The adaptive cruise control system and
braking guard do not react to people, an­
imals, objects crossing the road or on­
coming objects .
- The function of the radar sensor can be
affected by reflective objects such as
guard rails, the entrance to a tunnel,
heavy rain or ice.
- Never follow a vehicle so closely that you cannot stop your vehicle safely. The
adaptive cruise control cannot slow or
brake the vehicle safely when you follow
another vehicle too closely . Always re­
member that the automatic braking
function cannot bring the vehicle to a sudden or emergency stop under these
conditions.
- To prevent unintended operation, always
switch ACC
off when it is not being used.
{[) Note
The sensor can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. That could affect the adaptive cruise control system and braking guard.
Have your authorized Audi dealer or au­
thorized Audi Service Facility check their
function.
, In curves
App lies to vehicles: wi th Audi ada ptive c ruise contro l
Fig. 97 Example: d riving i nto a curve
When driving into a curve ~ fig. 97 and out of
a curve, the adaptive cruise control may react
to a vehicle in the next lane and apply the
brakes. You can override or prevent the brak­
ing by pressing the accelerator pedal briefly.
Stationary objects
Applies to vehicles : wi th Audi adapt ive crui se contro l
Fig. 98 Example: object changing lanes a nd stat ionary
object
The adaptive cruise control system only reacts
to objects that are moving or that the system
has already detected as moving. For example,
if a vehicle @, which has already been detect­
ed by the adaptive cruise control, turns or
changes lanes and another stationary vehicle
@ is located in front of that vehicle, the sys­
tem will not react to the stationary vehicle.
