If nothing is hung on the hooks, they will fold
back in by themselves.
In a collision, the laws of physics 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 p ick up ki­
netic energy which varies with the vehicle and
the weight of the item . Vehicle speed is the
most significant factor .
For example, in a frontal collision at a speed
of 30 mph (48 km/h), the forces acting on a 10-lb (5 kg) object a re about
20 times the
normal weight of the item. This means that
the weight of the item would suddenly be the
equ ivalent 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 .
8_ 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.
- Always use suitable retaining straps and
properly secure items to the tie-downs in
the luggage 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 r isk of injury.
Tie-downs
Applies to vehicles: with tie-downs
Four tie-downs for securing luggage pieces
and two for hanging bags , sacks, etc. are
lo­
cated in the luggage compartment.

· Bag hooks
Applies to vehicles: with bag hooks
Light objects can be secured on the hooks.

You can also use the hooks to hang light purs­
es, bags, etc.
_&. WARNING
The hooks can hold a maximum weight of
3 kg. Heavier objects are not adequately
secured. There is risk of personal injury.

.,. Slide the ski sack from the luggage com­
partment through the pass-through with
the z ipper at the rear ¢.&. -
Securing
.,. Insert the ski sack strap @ ¢fig. 91 in the
center buckle @.
.,. Pull the safety belt taut on the free end of
the belt @.
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 braking 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 protection. Always fasten the belt
tightly around the sack and its contents
¢fig. 91.
- 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 that all objects you are trans­
porting in the pass-through are secured.
Otherwise they could slide around during
sudden braking maneuvers and cause in­
juries.
(D} Tips
- Never stow the ski sack away when it is
still wet or damp (for example, snow
melting from skis). Allow it to dry com­
pletely before stowing it away.
- When transporting skis or snowboards,
tighten the securing strap between the
bindings. -
Position skis in the ski sack with the
pointed ends facing the front and ski
poles with the pointed ends facing the
rear.
- Sedan: You can lock or unlock the pass­
through using the mechanical key. This
prevents any access to the luggage com­
partment from the vehicle inte rior.

Audi adaptive cruise control and braking guard 101
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 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 107.
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. 113 Front of the vehicle: Position of radar sensor
The area that contains the radar sensor
c::;, fig. 113 must never be covered by stickers
or other objects or obstructed with dirt, in­
sects, snow or ice that will interfere with the
adaptive cruise control system and braking
guard. For information on cleaning, refer to
c::;, page 202. The same applies for any modifi­
cations made in the front area . The
function of the adaptive cruise control
system and braking guard is limited under
some cond itions:
- Objects can only be detected when they are
within sensor range
.:!>page 103 , fig. 116.
-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
c::;, page 102.
-Stationary objects c::;, page 102.
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 respons ible for start ing 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 collision. The driver is always responsible
for braking at the correct time.
- Improper use of adaptive cruise con trol
can cause collisions, other accidents and
serious personal injury .
- Never let the comfort and convenience
that adaptive cruise control and braking
guard offer d istract you from the need to
be alert to traffic conditions and the
need to remain in fullcontrolofyourve­
hicle at all times,
- Always remember that the adaptive
cru ise contro l and braking guard have
limits -they will not slow 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
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 .,.

@ V ehicles that are approaching
In certain cases, a vehicle will be classified as
cr itical for a lane change
even if it is still
somewhat far away. The fas ter a vehicle ap­
p ro aches, the sooner the disp lay in the exteri­
or m irror will t urn on.
@ Vehicles traveling with you
Vehicles traveling w ith you are indicated in the
exterior m irror if they are classified as cr it ical
for a lane change. All vehicles detec ted by
side assis t are in dicated by the time they en­
ter your "blind spot", at the latest.
© Vehicles left behind
If you s low ly pass a ve hicl e tha t sid e ass ist has
dete cted ( the difference in s peed between the
vehicle and you r vehicle is less than 9 mph
(15 km/h)), the display in the exter io r mirro r
turns on as soon as the vehicle enters your blind spot.
The disp lay wi ll not t urn on if you quickly pass
a vehicle that s ide assist has detected (t he d if ­
f erence in speed between the ve hicle and your
vehicle is greater than 9 mph (15 km/h)).
Functional limitations
T he radar senso rs are des igned to detect the
left and right adjacent lanes whe n the road
l anes a re the normal width. In certain situa­
t ions, the d isp lay in the exterior mirror may
turn on
even though there is no ve hicle locat­
ed in the area that is cr itical fo r a lane cha nge.
For example:
- if the lanes are narrow or if your are driving on the edge of your lane. If this is the case,
the system may have detected the vehicle in
another la ne that is
not adjacent to your
cur rent lane .
- if you a re driving through a c urve . Side assis t
may react to a vehicle that is one lane ove r
from the ad jacent lane .
- if side assist reacts to other objects (such as
high or d isp laced gua rd rails) .
- In poor weather conditions. The side assist fu nctions are limited .
Do not
cover the radar sensors c:;, fig. 127 with
stickers, depos its, bicycle wheels or other ob­
jects , because this will affect the funct ion. Do
not use s ide ass ist when tow ing a trail er. For
