Roof rack
Description and mounting locations
Additional cargo can be carried with a roof
luggage rack .
Fig. 75 Seda n: Roof ra ck atta chmen t po ints
Fig. 76 allroa d: Roof ra ck atta chm ent po ints
~ 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:
- Only use roof racks approved for your vehi ­
cle. These approved roof racks are the basis
for a complete roof rack system. Additional
attachmen ts or carrier systems are needed
to transport luggage a nd sports equ ipment .
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. 75 or¢ fig. 76 .
- We recommend that you keep the installa­
tion instructions for your roof rack system
together with your Owner 's literature in the
veh icle .
Sea ts a nd s to rage 69
When sh ould th e ro of rac k be r emo ved ?
-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 cons ump­
tion, wind noise and to guard against theft.
A 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
i:> fig . 75.
- The roof rack system must be installed
exactly according to the instruct ions 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
cur ren t conditions.
(D Note
- Your vehicle warranty does not cover any
damages to the veh icle caused by using
roof racks or mounting structures not
approved by Aud i for your veh icle. The
same app lies to damage resulting from
incorrect roof rack installation.
- Always check the roof rack mountings
and hardware before each trip and d ur­
ing a trip to make sure everything is se­
curely tightened. If necessary, retighten
the mountings and check the entire sys­
tem from time to time.
- After mounting a roof rack system, or
when you transport objects on the roof
of your vehicle, the height of the veh icle
is naturally increased. Be careful when
dr iving under low bridges or in parking
garages for example . This cou ld cause

@ Tips
For safety reasons, the par king brake is re­
leased au tomatically only when the dr iv­
er 's safety belt is engage d in the buckle.
Starting off with a trailer
To prevent rolling back unintentionally on an
incline , do the following:
~ Keep the switch @¢ page 87, fig . 101
pulled and depress the accelerator. The
park ing brake stays app lied and prevents
the vehicle from rolling backward.
~ You can release the switch @once you are
sure that you are develop ing enough dr iv ing
force at the wheels by depress ing the accel­
erator .
Depending on the weight of the r ig (vehicle
and trailer) and the severity of the incl ine, you
may roll backwards as you start . You can pre­
ve nt rolling backwards by holding the parking
b rake sw itch @pulled out and accelerating -
jus t as you would whe n starting on a hill with
a conventional hand brake.
Emergency braking
In the event that the conventional brake sys ­
tem fails or locks.
~ I n an eme rgency, pull the sw itch @
¢page 87, fig. 101 and continue to p ull it
to s low your vehi cle down wi th the pa rk ing
brake .
~ As soon as you release the switch @ or ac-
ce lerate, the braking process stops.
I f you pull the switch @and ho ld it above a
speed of about 5 mph (8 km/h), the emergen ­
cy braking function is initiated . The vehicle is
braked at a ll four wheels by activating the hy­
draulic brake system. T he brake performance
is similar to making an emergency stop ¢
&. .
In order not to activate the emergency brak ­
ing by m istake, an a udible warning tone (buz­
zer) sounds when the switch @is pulled. As
soon as the switch @ is released, or the accel-
On th e ro ad 89
erator peda l is depressed, eme rgency braking
stops.
A WARNING
Emergency braking should only be used in
an emergency, when the norma l foot brake
has fa iled or the brake pedal is obstructed.
Using the parking brake to perform emer­
gency b rak ing will slow your vehicle down
as if you had made a full bra ke application .
T he laws of physics cannot be suspended
even with ESC and its asso ciated compo­
nents (ABS, ASR , EDS) . In corners and
when road or weathe r conditions are bad,
a full brake application can ca use the vehi­
cle to sk id or the rear end to break away -
risking an accident.
Speed warning system
Overv iew
The speed warning system helps you to keep
your driving speed below a set speed limit.
The speed warn ing system warns if the driver
exceeds a previous ly stored max imum speed.
A war ning tone w ill so und as soon as the vehi­
cle speed exceeds the set speed by about 3 mph (3 km/h). At the same time, a warn ing
symbol appears in the display. The symbo l's
appearance might be different in some mod ­
els.
T he speed wa rn ing system has one or two*
warning thresholds that func tion independ ­
en tly of each othe r and that have somewhat
different purposes:
Speed warning 1
You can use speed warn ing 1 to set the maxi­
mum speed while you are d riving. This se tting
will re ma in in effec t unti l yo u t urn
off the ig ni­
tion, assuming that yo u have no t changed or
reset the setting.
T he . (USA models)/ . (Canada models)

Audi adaptive cru ise control and brakin g guar d 103
Vehicles with manual transmission
Applies to vehicles: with Audi adaptive cruise control
The adaptive c ruise control is avai lab le from
the 2nd gear through the 6th gea r in the cus­
tomary RPM.
When the adapt ive cruise control is turned on,
you must p ress the clutch to shift gears (as
usual) . When sh ifting normally or when press­
ing the cl utch, the adap tive c ruise control re­
mains turned on.
Afte r you have engaged the gear, you do
not
need to press the gas peda l. The adaptive
cru ise control accelerates automat ica lly if nec­
essary.
I f you press dow n on the clutch fo r too long or
shift/coup le improperly, the adaptive cruise
control may turn off automat ically.
{D) Tips
You cannot tu rn on the adapt ive cru ise
contro l during a sh ifting operation.
Audi adaptive cruise
control
Description
App lies to vehicles: with Audi adaptive cruise control
Fig. 1 16 Detect ion range
What can Audi a dapt ive crui se cont rol d o?
The adaptive cruise control works in conjunc ­
tion with a radar sensor installed in the front
of the vehicle
¢page 101, fig. 113, which is
subject to designated system limits
<=:> page 103 . Stationary objects are disregard­
ed . On open roads with no traffic, adaptive cruise
control works like a regular cruise contro l sys­
tem. The stored speed is maintained . When
approaching a moving vehicle detected up
ahead, the adaptive cruise control system au­
tomat ically 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 detec t a vehicle up
ahead, adaptive cruise contro l ac celerates
back up to the stored speed .
Which functions can be controlled ?
When you switch adaptive cruise control on,
you can set the current speed as the "contro l
speed "
¢ page 104, Switching on and off.
When dr iving, you can stop cru ise control
¢ page 105 or change the speed ¢page 105
at any time.
You can also set the distance to the object
ahead and set the adapt ive cru ise control driv ­
ing program
