Roof rack
Description and mounting locations
Additional cargo can be carried with a roof luggage rack .
Fig. 53 Roof rack attachment po in ts
.,. Always read and follow the instructions pro­
vided by the roof rack manufacturer when
insta lling 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. Add itional
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 c:;>fig. 53.
-We recommend that you keep the installa·
t ion instructions for your roof rack system
together with your Owner's literature in the
vehicle.
Wh en shoul d th e r oof rack b e re mo 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 fue l consump ­
tion, wind noise and to guard against theft.
A WARNING
- Use of an unapproved roof rack or incor·
rect mount ing of an approved roof rack
S ea ts a nd s to rage 59
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.
- On ly mount the roof rack on the desig­
nated locations on the roof¢
fig. 53.
- 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
current conditions .
(D Note
- Your vehicle warranty does not cover any
damages to the vehicle caused by using
roof racks or mounting structures not
approved by Aud i for your veh icle. The
same app lies to damage resul ting from
incor rect roof rack insta llation.
- Always check the roof rack mountings
and hardware before each trip and dur­
ing a trip to make s ure everyth ing 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 vehicle
is naturally increased. Be careful when
dr iving under low bridges or in parking
garages for example . This could cause
damage to the load and even the vehicle
itself.
- Make sure the open rear lid and the sun· roof* do not come into contact with the
roof rac k.

-Starting on inclines in stop-and-go traf­
fic: To help prevent the vehicle from roll­
ing back when starting, press and hold
the brake pedal for several seconds when
the vehicle is stationary .
(D Tips
You can find out if your vehicle is equipped
with Hill Hold by checking at an authorized
Audi dealer or qualified repair facility .
Speed warning system
Introduction
The speed warning system helps you to stay
under a specified maximum speed.
The speed warning system warns you if you
are exceeding the maximum speed that you
have set. You will hear a warning tone when
your speed exceeds the stored value by ap­ proximately 3 mph (3 km/h). An indicator
light . (USA models) . (Canada models) in
the instrument cluster display also turns on at
the same time. The indicator light./.
turns
off when the speed decreases below the
stored maximum speed .
Setting a threshold is recommended if you
would like to be reminded when you reach a
certain maximum speed. Situations where you may want to do so include driving in a country
with a general speed limit or if there is a
specified maximum speed for winter tires .
@ Tips
Even though your vehicle is equipped with
a speed warning system, you should still
watch the speedometer to make sure you
are not driving faster than the speed limit.
Setting the threshold
You can set, change and delete the threshold
in the MMI.
"' Select: Systems or Car systems > Driver as­
sist> Speed warning .
Driving 79
You can set any threshold between 20 mph (30 km/h) and 150 mph (240 km/h). Settings
can each be adjusted in increments of 6 mph
(10 km/h).
Cruise control system
Description
Applies to vehicles: with cruise control system
The cruise control system makes it possible to
drive at a constant speed starting at 15 mph
(20 km/h).
The speed is kept constant by modifying en­
gine power or through an active brake inter­
vention.
.&_ 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 vehicle and other vehicles.
- For reasons of safety, cruise control
should not be used in the city, in stop­
and-go traffic, on winding roads and
when road conditions are poor (such as ice, fog, gravel, heavy rain and hydro­
planing) -you could have an accident.
- Switch the cruise control
off temporarily
when driving in turning lanes, highway
exits or in construction zones.
- Please note that unconsciously "resting"
your foot on the accelerator pedal pre­
vents the cruise control from braking.
This is due to the control system being
overridden by the driver's acceleration.
- If a brake system malfunction such as
overheating occurs when the cruise con­
trol system is switched on, the braking
function in the system may be switched
off. The other cruise control functions re­
main active as long as the indicator light
II (US models) !l'I (Canadian models)
ison.

to the stored distance . If the object detected
ahead accelerates, adaptive cru ise control w ill
also accelerate up to the stored speed .
The hig her the speed, the greater the distance
in meters ¢

ommended. That is equal to the general rec­
ommendation of "half the speed shown on
the speedometer ".
The distances provided are example values. Depending on the driving situation, the cur­
rent speed and the way the object detected
ahead is driving, the actual distance may be
more o r less than these target distances .

Fig . 87 Driving situations
I AUDI
Fi g. 88 Rear of the vehicle: sensor posit ions
Side assist functions at speeds above approx i­
mately 19 mph (30 km/h).
@ Vehicl es th at ar e 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 roaches, t he sooner the display in the exteri­
or m irror will t urn on.
@ V ehicles traveling with you
Vehicles traveling w ith you are indicated in the
exterior m irror if they are classified as cr itical
for a lane change. All vehicles detec ted by
side assist are indicated by the time they en­
t er your "blind spot", at the latest.
Audi side assist 99
© Veh icles left behind
If you s low ly pass a vehi cle that s ide assist has
detected (the difference in speed between the
vehicle and you r vehicle is less than 9 mph or
15 km/h), the display in the exterio r mir ro r
turns on as soon as the vehicle enters your blind spot.
T he disp lay will not t urn on if you quickly pass
a vehicle that side assist has detected (the dif­
ference in speed between the veh icle and your
vehicle is greater than 9 mph or 15 km/h).
Functional limitations
The radar sensors are designed to detect the
left and right adjacent lanes when the road
lanes are the normal width. In some sit ua­
tions, 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 for 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 lane that is
not adjacent to you r
current lane .
-If you are dr iving through a curve . S ide as­
sis t may react to a vehicle that is one lane
over from the adjacent lane.
- If side assist reacts to other objects (such as
high or d isp laced guard rails) .
- In poor weather conditions. The side assist
functions are limited .
Do not cover the radar sensors
c> fig. 88 with
stickers, depos its, bicycle wheels or other ob­
jects, because this will affect the funct ion. For
information on cleaning, see
c> page 201 .
A WARNING
-Always pay attention to traffic and to the
a rea a round your ve hicl e. Side assi st can­
not repla ce a d river's attention. The driv ­
er a lone is always responsible for la ne
cha nges and s imilar dr iv ing ma ne uvers.
- In some si tua tions, the system may not
function or its function may be limited.
F or examp le:

100 Audi side assist
-If vehicles are approaching or being
left behind very quickly. The display
may not turn on in time.
- In poor weather conditions such as
heavy rain, snow or heavy mist.
- On very wide lanes, in tight curves, or if
there is a rise in the road surface.
Vehicles in the adjacent lane may not
be detected because they are outside
of the sensor range.
- Side assist cannot detect all vehicles un­
der all conditions- danger of accident!
- Please note that side assist indicates
there are approaching vehicles, or
vehicles in your blind spot, only after
your vehicle has reached a driving speed
of at least 19 mph (30 km/h).
- In certain situations, the system may not
function or its function may be limited.
For example:
- if vehicles are approaching or being left
behind very quickly. The display may
not turn on in time.
- in poor weather conditions such as heavy rain, snow or heavy mist.
- on very wide lanes, in tight curves or if
there is a rise in the road surface.
Vehicles in the adjacent lane may not
be detected because they are outside
of the sensor range.
The sensors can be displaced by impacts or damage to the bumper, wheel housing and
underbody. This can affect the system. Have your authorized Audi dealer or quali­
fied repair facility check their function.
(D Tips
-If the window glass in the driver's door
or front passenger's door has been tint­
ed, the display in the exterior mirror may
