I n a coll is ion, the laws of phys ics mean that
even smaller items that are loose in the vehi­
cle will turn into heavy missiles that can cause
serious injury . Items in the vehicle pick up ki­
netic energy which varies with the vehicle and
the weight of the item. Vehicle speed is the
most s ignificant factor.
F or example, in a frontal collis ion at a speed
of 30 mph (48 km/h), the forces acting on a
10-lb (4.5 kg) object are about
20 times the
normal weight of the item. This means that
the we ight of the item would suddenly be the
Seats and storage 69
equivalent of about 200 lbs (90 kg). One can
easily imagine the injuries that an item of that
weight flying freely through the passenger compartment can cause in a collision at a
speed considered relatively low.
A WARNING
Weak, damaged or improper straps used
to secure items to tie-downs can fail dur­
ing hard braking or in a collision and cause
serious personal injury.
-Al ways use su itable retaining straps and
prope rly secure items to the tie-downs in
the lu ggage compartment to help pre­
vent items from shifting or flying for­
ward.
- Never attach a child seat tether strap to
a tie-down.
- For strength-related reasons, the mount­
ing hooks can only be used to secure ob­
jects weighing up to 10 lb. (5 kg). Heavi­
er objects will not be adequately secured
- there is a risk of injury.

A WARNING
-The ski sack is intended only for the
transportation of skis and other light ob­
jects. To reduce the risk of serious per­
sonal injury, never transport heavy or pointed objects in the ski sack.
- When brak ing rapidly or during an acci­
dent, the load could be displaced and
cause injury to occupants.
- Sharp edges on the load must be covered
for protect ion. Always fasten the belt
t ightly around the sack and its contents
~fig. 73.
-For safety reasons, do not transport
more than two pairs of skis in the ski
sack.
- You must secure the ski sack with the strap after loading.
- Make sure all objects that you are trans­
porting in the pass-th rough a re secured.
Otherwise they cou ld slide around during
s u dden braking maneuvers and cause in­
jury.
(D Tips
- Never stow the sk i sack away when it is
still wet or damp ( for example, snow
melting from skis). Allow it to dry com­
plete ly before stowing it away.
- Position skis in the ski sack w ith the
pointed ends facing the front and ski
po les w ith the pointed ends facing the
rear.

spaces -danger of asphyx iation.
- Never turn off the engine until the vehi­
cle has come to a complete stop.
- The brake booster and power steering
only work when the engine is running. If
the engine is off, you have to use more
force when steering or braking. Because
you cannot steer and brake as you usual­
ly would, this could lead to crashes and
serio us injuries.

A WARNING
-Always pay attention to traffic even when
the cruise control is switched on . You are
always responsible for your speed and
the distance between your vehicle and other vehicles.
- For safety reasons, the cruise control

when road conditions are poor (such as
ice, fog, grave l, heavy rain and hydro ­
planing) -risk of accident .
- Turn off the cruise control temporari ly
when entering 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 cruise control is overridden
by the driver's acce leration.
- If a brake system malfunction such as
overheating occurs when the cruise con­
trol system is sw itched on, the braking
function in the system may be switched

Audi adaptive cruise
control and braking
guard
Introduction
App lies to vehicles: with Audi adaptive cruise control
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 helps to make driv­
ing more comfortable both on long highway
stretches and in stop-and-go traffic.
The braking guard system can warn you about
an impending collision and initiate braking
maneuvers ¢
page 99.
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
Applies to vehicles: with Audi adaptive cruise control
Fig. 93 Front of the vehicle: sensors and video came ra
The areas that contain the radar and ultrason ­
ic sensors and the v ideo camera ¢
fig. 93
must neve r be covered by stickers or other ob­
jects or obstructed with dirt, insects, snow or
ice that will interfere with the adaptive cruise
control system and braking guard. For infor­
mation on cleaning, refer to ¢
page 218. The same applies for any modifications made in
the front area.
T he function of the adaptive cru ise contro l
system and braking guard is limited under
some conditions:
- Objects can on ly be detected when they are
w ith in sensor range
¢page 95, fig. 96 .
-The system has a limited ability to detect
objects that are a shor t distance ahead,
off
t o the side of your vehicle or moving into
your lane.
- Some kinds of ve hicles 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 94 .
- Stationary objects¢ page 94.
& WARNING
Always pay attent ion to traffic when adap ­
tive cruise control is switched on and brak­ ing g uard is active. As the driver, you are
still respons ible for starting and for ma in­
taining speed and distance to other ob­
jects . Braking guard is used to assist you .
The driver must always take action to avo id
a collision. The driver is always responsible
for braking at the co rrect time.
- Improper use of adaptive cru ise control
can cause collisions, other acc idents and
serious pe rsonal in jury.
- Never let the comfort and conven ience
that adaptive cruise control and braking
guard offer d istract you from the need to
be alert to traffic condit ions and the
need to rema in in full control of your ve­
hicle at all times,
- Always remember that the adaptive
cruise control and braking guard have
limits -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 .

control
Description
Applies to vehicles: with Audi adaptive cruise co ntrol
Fig. 96 Detectio n range
What can adaptive cruise control do?
The adaptive cruise control system uses video,
radar and ultrasound . Moving vehicles ahead
can be recognized up to about 650 feet (200 m) away.
On open roads w ith no traff ic, adaptive cruise
control works like a regular cruise control sys­
tem. The stored speed is maintained . When
approaching a moving vehicle detected up
ahead, the adaptive cruise control system au­
tomatically slows down to match that vehi­
cle's speed and then maintains the distance
that the driver previously stored. As soon as
the system does not detect a vehicle up
ahead, adaptive cruise control accelerates
back up to the stored speed.
In stop-and-go traffic, adaptive cruise control
can brake until the vehicle stops and acce ler­
ate again under certain conditions and if this
is possible within the system 's limits and ca­
pabilities
c> page 97 . Adaptive cruise control
will not make an emergency stop .
Which functions can be controlled?
When you switch adaptive cruise contro l on,
you can set the current speed as the "control speed"
c> page 95, Switching on and off.
When driving, you can stop cruise control

wheel vibration
Applies to vehicles: with lane assist
You can adjust individual settings in the MMI.
.. Se lect: ICARI function button> Car systems
control button > Driver assist > Audi lane
assist .
Setting the warning point
Early: With this setting, a warning is provided
before a wheel touches the detected lane
boundary line . The warning depends on the
angle in which the veh icle is approaching the
line. The distance at which the warning is giv­
en increases as the angle becomes sharper. If
you dr ive towa rd a boundary line at a very
sha rp angle, the warning will come just before
a wheel touches the line.
Medium : With this setti ng, the warn ing po int
is adapted to the course of the road, the lane
width and the speed. You wi ll sti ll be warned
if you cross slightly over a dotted line when
driving on curves.
Late : This setting has the same properties as
medium. You will only be warned once a
wheel crosses a detected line.
Setting the steering wheel vibration
The steering wheel v ibration can be set to
Low , Medium or Strong . Selecting each of the
settings will cause the steering wheel to vi­
b rate so you can check the strength of the vi­
bration in that setting.
(D Tips
Your settings are automatically stored and
assigned to the remote contro l key being
used .
