Description
Applies to: vehicles with Audi adaptive cruise contro l
Fig. 96 Instrument cluster: approach warning
Braking guard uses radar sensors and a video
camera. It also functions within the limits of the
system when adaptive cruise control is switched
off.
What can braking guard do?
When detected in time, the system can assess
situations when a vehicle ahead brakes suddenly
or if your own veh icle is traveling at a high speed
and approaching a vehicle up ahead that is mov­
ing more slowly. Braking guard does not react if
it cannot detect the si tuat ion.
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 . T he indicator light .
in the d isplay comes on .
- The
approach warning is given when a detected
vehicle up ahead in your lane is moving much
more slowly than you are or if it brakes sharply.
When this warning is g iven, it may only be pos­
s ib le to avoid a collision by swerving or braking
sharp ly. The indicator light. and indicator in
the display will warn yo u about the danger
¢
fig. 96. You will also hear an acoustic signa l.
If you do not react fast enough or do not react at
all to the situation, braking guard will intervene
by braking.
N "' ll This is not available in some countries . ......
-If a collision is imminent, the system wi ll first
provide an
acute warning by briefly and sharply
apply ing the brakes .
- If you do not react to the acute warning, brak­
ing guard can brake with increas ing force with­
in the limits of the system. This reduces the ve­
hicle speed in the event of a collision.
- The system can initiate maximum braking
shortly before a collision
1 ). Full dece leration at
high speeds occurs only in vehicles with adap­
tive cruise control and side assist (pre sense plus).
- If the braking guard senses that you are not
braking hard enough when a collision is immi­
nent, it can increase the braking force.
- The pre sense functions also engage when a
collision is imm inent ¢
page 177.
Which functions can be controlled?
You can switch braking guard and the distance/
approach warning on or off in the MMI
¢ page 86, Settings in the Infotainment sys­
tem .
A WARNING
--
Lack of attention can cause collisions, other
accidents and serious personal injuries. The
braking guard is an assist system and cannot
prevent a collision by itself . Th e driver must
always intervene. The driver is always respon­
sib le for b raking at the co rrect time.
- Always pay close attention to traffic, even
when the braking guard is switched on. Be
ready to intervene and be ready to take
complete control whenever necessary. Al­
ways keep the safe and legal distance be­
tween your vehicle and vehicles up ahead.
- Brak ing guard works with in limits and will
not respond outside the system limits, for
example when approach ing a stopped vehi­
cle or stationary obstacle (end of a traffic
jam or vehicle that has broken down in traf­
f ic).
- Always remember that the radar sensor for
the 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 detected
at all.
- Reflective surfaces including crash barriers
or tunnel entrances may impair the function
of the radar sensor.
@ Tips
- You can cancel the braking with increasing
force that is initiated by the system by brak­
ing yourself, by accelerating noticeably or
by swerving .

page 86.
- Keep in mind that braking guard can brake
unexpectedly. Always secure any cargo or
objects that you are transporting to reduce
the risk of damage or injury.

Automatic transmission tiptronic
Introduction
The automat ic transmission is controlled e lec­
tron ically. The transmission upshifts or down­
shifts automatically depending on wh ich drive
p rogram is selected.
When a
moderate driving style is used , the
transmission selects the most economical driving
mode.
It will then change up early and delay the
downshifts to give bette r fu el economy .
The transm iss ion switches to a sporty mode after
a kick-down or when the driver uses a
sporty
driving style
character ized by quick accelerator
pedal movements, heavy acceleration, frequent
changes in speed and traveling at the maximum
speed.
If desired, the dr iver can also select the gears
manually (tiptronic mode) ¢page 105.
In the tiptron ic transmission, power is transfer­
red by a torque converte r.
Selector lever positions

The selector lever position engaged appears next
to the selector lever as well as in the instrument
cluster display .
P -Park
In th is selector lever pos ition the transm iss ion is
mechanically locked . Engage P only when the ve­
hicle is
completely stopped¢.&. in Driving the
automatic transmission on page 103.
Automatic transmission
T o shift in or out of position P, you must first
press and hold the brake pedal and then press
the release button in the selector lever handle
while moving the selector lever to or from P . You
can shift out of this position only with the igni­
tion on .
R - Reverse
Select R only when the vehicle is at a full stop
and the engine is running at idle speed¢ & in
Driving the automatic transmission on
page 103.
Before you move the selector lever to R, press
both the button in the hand le of the selector lev­
er
and the brake pedal at the same time.
When the ignition is on, the backup lights illumi­
nate when the selector lever is moved into R .
N -Neutral
The transmission is in neutra l in this position .
Shift to this position for standing with the brakes
applied
¢ & in Driving the automatic transmis­
sion on page 103 .
When the vehicle is stat ionary or at speeds be low
1 mph (2 km/h) , you must always apply the foot­
brake before and whi le moving the lever out of N.
DIS -Normal position for driving forward
In the D/S position, the transmission can be op­
erated either in the normal mode Dor in the
sport mode S. To select the sport mode S, pull
the selec tor lever back briefly. Pulling the leve r
back again will select the normal mode D . The in­
strument cluster display shows the selected driv­
ing mode.
In the normal mode D, the transmission auto­
matically selects the suitable gear ratio. It de­
pends on engine load, vehicle speed and drivin g
style.
Select the sport mode S fo r spo rty driving. The
vehicle makes full use of the engine 's powe r.
Shifting may become noticeable when accelerat­
ing.
When the vehicle is stat ionary or at speeds below
1 mph (2 km/h), you must always apply the foot ..,.

vehicle is sta tionary or at speeds below 1 mph
(2 km/h) .
At speeds above about 1 mph (2 km/h) the Auto ­
matic Shift Lock is automatically deactivated in
the N position.
A t ime delay element prevents the selector lever
from locking when it is moved through the N po­
sition (going from R to D/S). The locking element
will lock the selector lever if the lever is left in N
(Neutral) for more than approximately 2 second,
without the brake pedal being pressed .
Release button
The release button on the selector lever prevents
the lever from being accidentally shifted into cer­
tain positions . Depending on the direction of the
shift, the selector lever locks at different posi­
tions . The positions are highlighted in the illus ­
tration

celerate.
Stopping temporarily
.. Keep the vehicle stationary using the braking
pedal, for example at traffic lights.
.. Do not press the accelerator pedal when doing
this .
.. To prevent the vehicle from rolling when you
start driving, set the parking brake wh en stop ­
ping on steep inclines¢,& .
.. The parking brake will release au tomatically
and the vehicle will start moving once you press
the accelerator pedal.
Stopping/ parking
If the selector lever is not in the P position when
you open the drive r's door, the vehicle could roll.
The message

.. Select the P selector lever position ¢ ,& .
Automatic transmission
Stopping on an incline
.. Always press the brake pedal to hold the vehi­
cle in pla ce and prevent it from "ro lling back"
¢ ,& . Do
not try to prevent the vehicle from
"rolling back" when a gear is engaged by in ­
creasing the engine speed ¢CI) .
Starting on an incline
.. Activate the parkin g brake .
.. With the driving gear selected, press the accel­
erator pedal carefully. The parking brake will
releas e automatically if your seat belt is fas­
tened.
Under certain circumstances, such as driving in
the mountains, it may be useful to switch tempo­
rarily to the manual shift program in order to ad­
ju st the gears to the driving conditions by hand
¢ page 105 .
On slopes, activate the parking brake first and
then move the selector lever to the P position .
This prevent s too much stress from being placed
on the locking mechanism.
A WARNING
=
- The vehicle can also roll when the eng ine is
stopped .
- Unintended vehicle movement can cause se­
rious injury .
- Never leave your veh icle w ith the engine
running while in gear . If you must leave
your veh icle when the engine is running, ac­
tivate the parking brake and move the selec­
tor lever to P.
- Power is still transmitted to the wheels
when the engine is runn ing at idle. To pre­
vent the vehicle from "creeping", yo u must
keep your foot on the brake when the en­
gine is running and the selector lever is in D/
5 or R or "tiptronic" mode is selected .
- Do not press the accelerator pedal when
changing the se lector lever position while
the vehicle is stationary and the engine is running .
- Never shift into R or P whi le driving.
103

Automatic transmission
-Before driving down a steep slope, reduce
your speed and shift into a lower gear with
"tiptron ic".
- Do not ride the brakes or press the brake
pedal too often or too long when driving
down a hill. Constant braking causes the
brakes to overheat and substantially re­
duces braking performance, increases brak­
ing distance or causes complete failure of
the brake system.
- To prevent the vehicle from rolling back
when stopping on inclines, always hold it in
place with the brake pedal or parking brake.
- Never hold the vehicle on an incline with a
slipping clutch. The clutch opens automati­
cally when it becomes too hot from the
overload. An indicator lamp
[i'J illuminates
and a driver message appears
¢ page 105
when the clutch is overloaded.
- If the engine must remain running, never
have any driving position engaged when
checking under the hood. Make sure these­
lector lever has securely engaged and is
locked in P with the parking brake set
¢ page 203. Otherwise, any increase in en ­
gine speed may set the vehicle in motion,
even with the parking brake applied .
@ Note
-When stopping on an incline, do not try to
hold the vehicle in place by pressing the ac­
celerator pedal while a driving gear is se­
lected . This can cause the transmission to
overheat and can damage it . Activate the
parking brake or press the brake pedal to
prevent the vehicle from rolling.
- Allowing the vehicle to roll when the engine
is stopped and the selector lever is in N will
damage the transmission because it is not
lubricated under those circumstances.
(D Tips
For safety reasons, the parking brake is re­
leased automatically only when the driver's
safety belt is engaged in the buckle.

· Hill descent control
The hill descent control system assists the driver
when driving down declines .
Hill descent control is activated when the selec­
tor lever is in D/S and you press the brake pedal.
The transmission automatically selects a gear
that is suitable for the incline. Hill descent con­
trol tries to maintain the speed achieved at the
time of braking, within physical and technical
limitations. If may still be necessary to adjust the
speed with the brakes.
Hill descent control switches off once the decline
levels out or you press the accelerator pedal.
On vehicles with the cruise control system*
Q page 77, hill descent control is also activated
when the speed is set.
A WARNING
Hill descent control cannot overcome physical
limitations, so it may not be able to maintain
a constant speed under all conditions. Always be ready to apply the brakes.

Manual shift program
Using the manual shift program you can man­
ually select gears.

Automatic transmission
using the shift paddles, move the selector lever
to the right out of the D/S position.
When accelerating, the transmission does
not
automatica lly shift to the next gear shortly be­
fore the maximum permitted engine RPM is
reached.
If you have selected a lower gear than the current
one, the automatic transmission will shift down
only when the engine wi ll not be over-revved.
With kick-down, the transmission shifts into a
lower gear depending on speed and engine RPM.
@ Tips
Tiptronic is inoperative when the transmission
i s in the fail-safe mode.
Kick-down
Kick-down enables maximum acceleration .
When you depress the accelerator pedal beyond
the resistance point, the automat ic transmission
downsh ifts into a lower gear, depending on vehi­
cle speed and engine speed. The upsh ift into the
next higher gear takes place once the maximum
specified engine speed is reached.
& WARNING
Please note that the drive wheels can spin if
kick-down is used on a smooth slippery road -
there is a risk of skidding.
Transmission malfunction
DI Transmission: Press brake pedal and select
gear again
Press the brake pedal and select the desired se­
lector lever position again. You can then continue
driv ing.
DI Transmission overheating: Please drive con­
servatively
T he transmission temperature has increased sig­
nificantly due to the sporty driv ing manner. Drive
in a less sporty manner until the temperature re­
tu rns to the normal range and the indicator light
switches of.
