A WARNING
- Always pay attention to the traffic
around you when the cruise control is in
operation . You are always responsible for
your speed and the distance between
your veh icle and other vehicles . .,,.

82 On the road
-For reasons of safety, cruise contro l
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, gravel, heavy rain and hydro­
planing) - risk of accident .
- Turn off the cruise control temporar ily
when ente ring turn lanes, highway exit
lanes or in construction zones.
- Please note that inadvertently "rest ing"
yo ur foot on the accelerator peda l causes
the cruise control not to brake. This is
because the cr uise con trol is overridden
by the d river 's acce lerat ion.
- If a bra ke system malfunction such as
overheat ing occurs when the cru ise con­
tro l system is sw itched on, the braking
function in the system may be switched
off. The othe r cruise control f unctions re­
ma in active as long as the indicator light
@;rn~i~ (US models) !lB (Canadian mod­
els) is on.
The brake lights illuminate as soon as the brakes apply automatically.
Changing speed

010 direction unti l the de­
s ired speed is d isplayed.
You can also press the accelerator pedal down
to increase your speed, e.g. if you want to
pass someone. The speed yo u saved earl ier
will resume as soon as you let off of the accel ­
erator pedal.
I f, however, you exceed your saved speed by
6 mph ( 10 km/h) for longe r than 5 m in utes,
the cruise cont ro l w ill be turned off tempo ra­
rily. The green symbol in the display turns
white. The saved speed remains the same.

speed.
A WARNING "'---
You shou ld only return to the saved speed
if it is not too fast for the current traffic
conditions - r isk of an accident!

86 Transmission
-Unintended vehicle movement can cause
serious injury .
- Never leave your vehicle with the engine
running while in gear. If you must leave
your vehicle when the engine is running,
activate the parking brake and move the
selector lever to P .
- Power is still transmitted to the wheels
when the engine is running at idle. To
prevent the vehicle from "creeping", you
must keep your foot on the brake when
the engine is running and the selector
lever is in D/S or R or "tiptronic" mode is
selected.
- Do not press the accelerator pedal when
changing the selector lever position
while the vehicle is stationary and the
engine is running.
- Never shift into
R or P while driving.
- Before driving down a steep slope, re-
duce your speed and shift into a lower
gear with "tiptronic".
- 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
braking distance or causes complete fail­
ure 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 auto­
matically when it becomes too hot from
the overload . An indicator lamp
l'§J illu­
minates and a driver message appears
Q page 88 when the clutch is overload­
ed.
- If the engine must remain running, never
have any driving position engaged when
checking under the hood. Make sure the
selector lever has securely engaged and
is locked in P with the parking brake set
Q page 195. Otherwise, any increase in
engine speed may set the vehicle in mo- tion
, even with the parking brake ap­
plied.
@ Note
- When stopping on an incline, do not try
to hold the vehicle in place by pressing
the accelerator pedal while a driving gear is selected. This can cause the transmis­
sion to overheat and can damage it. Acti­
vate the parking brake or press the brake
pedal to prevent the vehicle from rolling .
- Allowing the vehicle to roll when the en­
gine is stopped and the selector lever is
in N will damage the transmission be­
cause it is not lubricated under those cir­
cumstances.
(D Tips
For safety reasons, the parking brake is re­
leased automatically only when the driv­
er'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 these ­
lector lever is in D/S and you press the brake
pedal. The transmission automatically selects
a gear that is suitable for the incline. Hill de ­
scent control tries to maintain the speed ach­
ieved at the time of braking, within physical
and technical limitations. It may st ill be nec­
essary to adjust the speed with the brakes.
Hill descent control switches off once the de­
cline levels out or you press the accelerator
pedal.
On vehicles with the cruise control system*
Q page 81 , hill descent control is also activat­
ed 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

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 regulating 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
c:::> page 96.
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 co ntrol
Fig. 103 Front of the vehicle: Position of radar senso r
The area that contains the radar sensor
c:::> fig. 103 must never be cove red by stickers
or other objects or obstructed with dirt, in­
sects, snow or i ce that will interfere with the
adaptive cruise control system and braking
guard. For information on cleaning, refer to
c:::> page 184. The same applies for any modifi­
cations made in the front area . T
he function of the adaptive cruise cont rol
system and braking guard is limited under
some condit ions:
- Objects can only be detected when they are
within sensor range
c:::>page 92, fig . 106.
-The system has a limited ability to detect
objects that are a short d istance 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
c:::> page 91.
-Stat ionary objects c:::> page 91 .
A WARNING
-
Always pay attention to traffic when adap-
tive cruise contro l is switched on and brak­
ing guard is active. As the driver, you are
still respons ible for starting and for main­
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 col lision. The driver is always responsible
for braking at the correct time.
- Im proper use of adaptive cruise con trol
can cause collisions, other accidents and
serio us personal injury.
- Never let the comfor t and convenience
that adaptive cruise control and braking
guard offer distract you from the need to
be alert to traffic conditions and the
need to remain in full control of your ve­
h icle at a ll times,
- Always remember that the adaptive
cru ise contro l and brak ing guard have
lim its -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 or disabled vehicle.
If registered by the radar sensor, vehicles
or obsta cles that are not moving can
trigger a co llision warning and if
