A WARNING ... -
-The ski sack is intended only for the
transportation of skis and other light ob­
jects. To reduce the risk of ser io us 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 disp laced and
cause injury to occupants.
- Sharp edges o n the load must be covered
for protection. Always fasten the belt
tightly around the sack and its contents. _...

7 2 Seats and storage
-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-through are secured.
Otherwise they could slide around during
sudden braking maneuvers and cause in­
jury.
Q) 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 .
- Position skis in the ski sack with the
pointed ends facing the front and ski
poles with the pointed ends facing the
rear.
Roof rack
Description and mounting locations
Additional cargo can be carried with a roof
luggage rack.
Fig. 77 Roof rack attac hment points
,. Always read and follow the instructions pro­
vided by the roof rack manufacturer when
installing the roof rack system .
If luggage or cargo is to be carried on the
roof, you must observe the following:
- To enhance the vehicle's streamlined design,
rain gutters have been molded into the roof.
It is not possible to use normal roof racks.
Only install a roof rack specifically designed for your model AB. Contact the nearest Audi
dealer for information on approved modular
roof racks for your vehicle.
- Only use roof racks approved for your vehi­
cle. These approved roof racks are the basis
for a complete roof rack system. Additional
attachments or carrier systems are needed
to transport luggage and sports equipment.
We recommend using roof racks from the
Audi original accessories program .
- When installing the roof rack, make sure it
is only mounted on the designated locations
on the roof~
fig. 77 .
- We recommend that you keep the installa­
tion instructions for your roof rack system
together with your Owner's literature in the
vehicle .
When should the roof rack be removed?
-Before going through an automatic car wash
(it is best to ask the car wash operator for
advice)
- When not in use, to reduce fuel consump­
tion, wind noise and to guard against theft .
8,. WARNING
-Use of an unapproved roof rack or incor­
rect mounting of an approved roof rack
can cause the roof rack or the items at­
tached to it to fall off the roof onto the
road.
- Objects falling from the roof of a vehicle
can cause a crash and personal injury.
- Only mount the roof rack on the desig­
nated locations on the roof¢
fig. 77.
- The roof rack system must be installed
exactly according to the instructions pro­
vided.
- When driving with a roof rack system,
changes to the center of gravity and wind
resistance can change the vehicle han­
dling and lead to a collision. Always
adapt your driving and your speed to the
current conditions.

A WARNING
- Never allow the engine to run in confined
spaces -danger of asphyxiat ion.
- 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
serious injuries.
(D Note
- Avo id h igh engine rpm, full throttle and
heavy engine loads until the eng ine has
reached operating temperature -other­
w ise you risk engine damage .
- T he engine cannot be started by pushing
or towing the vehicle.
(0 Tips
- After a co ld eng ine is started, there may
be a brief period of inc reased no ise be­
cause oil pressure must first build up i n
the hydraulic valve adjusters. This is nor­
ma l and not a cause for conce rn.
- If you leave the veh icle with the ignition
switched on , the ign ition w ill switch off
after a certain period of time . Please
note that electrical equ ipment such as
exterior lights will sw itch off as well
when that happens.
Stopping the engine
• Bring your vehicle to a complete stop.
• Move the selector lever to the P or
N posi ­
tion.
• Pr ess the I START ENGINE STO P I button

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 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
c:::> page 98.
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.

The areas that conta in the radar and ultrason­
ic sensors and the v ideo camera
c:::> fig. 96
must neve r be cove red by stic kers or other ob­
jects or obstructed w ith dirt, insects, snow or
i ce that will interfere with the adaptive cruise
control system and braking guard. For infor­
mation on cleaning, refer to
c:::> page 214. 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 cond itions:
- Objects can only be de tected when they are
w ith in sensor range
c:::> page 94, fig. 99.
- The system has a limited ability to detect
objects that are a short d istance ahead, off
to the side of your vehi cle or mov ing into
your lane.
- Some kinds of veh icles are hard to detect;
for examp le motorcycles, veh icles 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 93 .
-Stat ionary objec ts c:::>page 93.
& WARNING
A lways pay attention to traffic when adap­
tive cruise contro l is switched on and brak­
ing g uard is active. As the driver, you are
still respons ible for starting and for main­
taining speed and distance to other ob­
jects. Braking guard is used to assist you .
The dr iver must a lways take action to avo id
a collis ion . The driver is a lways respons ible
fo r braking a t the co rrec t 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 convenience
that adaptive cruise control and braking gua rd offer d istract you from the need to
be alert to traffic condit ions and the
need to remain in fu ll control of your ve­
hicle at a ll 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 o r disabled vehicle.

Audi adaptive cruise
control
Description
Applies to vehicles: with Audi adaptive cruise control
Fig. 99 Detectio n range
What can adaptive cruise control do?
The adaptive cruise control system uses video,
radar and ultrasou nd . Moving vehicles ahead
can be recognized up to about 650 feet (200 m) away.
On open roads w ith no traffic, 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 s lows down to match that vehi­
cle's speed and then maintains the distance
that the driver previous ly 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, adapt ive cru ise control
can brake until the vehicle stops and acceler ­
ate again under certain conditions and if this
is possible within the system's limits and ca­
pabilities ¢
page 96. Adaptive cru ise 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" ¢
page 94, Swi tching on and off.
When driving, you can stop cruise control
¢
poge 96 or change the speed ¢ page 95
at any time.
You can also set the distance to the object
ahead and set the adaptive cruise control driv­
ing program ¢
