Trail er to wing
If you have to drive th rough diffic ult road condi­
tions, you can raise the vehicle again after hitch ­
ing the trai ler or after adjust ing the tongue
weight .
{QJ Note
Applies to: vehicles with air suspension
-Changes in temperature or load can affect
the he ight of the vehicle.
- Set the a ir suspension to the standard vehi­
cle heig ht, otherwise the applicab le tongue
weig ht no longer applies to your vehicle .
(D Tips
-Use chocks when parking on incl ines if the
trailer is loaded.
- We recommend also having the vehicle in­ spected between the inspection intervals if
you are towing a trai ler frequently.
- Avo id driving wit h a trailer du ring the vehi­
cle break-i n period .
Driving with a trailer
Driving with a trailer requires extra caution.
Speed
Adhere to the legal speed l imi ts. Follow t he lega l
regulations specif ic to the country.
As the speed inc reases, the d riving stability of
the t railer dec reases . The refore you sho uld not
exceed t he max imum legal speed limit when
there are unfavorable road, weather and/or wind
conditions. This especially applies when driving
downhill.
You must a lways reduce yo ur speed as soon as
you not ice even the s lightest swinging motion of
the trailer . Never try to "straighten out" the trail ­
er by accelerating.
The weig ht dis trib ution is very poo r if t he ve hicle
is empty and the trailer is loaded. However if you
must drive under these circumstances, t hen drive
especia lly slowly.

Brak es
Brake in a time ly manner. Downs hift be fo re dr iv ­
i ng down hill so that the engine can assist with
braking ~&, .
When using a t railer w it h over run bra kes, fi rst
brake ge ntly t hen q uickl y. This red uces the r isk o f
jerking while braking if the trailer wheels lock up .
Engine coolant temperatur e
Pay attention specifically to the coolant tempera­
ture display when there a re high outs ide temper­
at ures , and whe n driving on long i nclines
~ page 11. Shift to a highe r gear in a t imely man­
ner .
A WARNING
Constant braking causes the b rakes to over­
h eat and substantially reduces bra king per ­
formance, increases b raking distance o r caus­
es complete failure of the brake system.

Description
App lies to: vehicles with speed warning system
The speed warning system helps you to stay be­
low a specified maximum speed that can be set,
changed or deleted in the Infotainment system .
The speed warning system warns you if you are
exceeding the maximum speed that you have set .
A warning tone will sound as soon as your speed
exceeds the stored value slightly . The indicator

p lav
[0] (USA models)/ [81 (Ca nada models) and
a message. The indica tor l igh t
[0]/ [OJ and the
message turn off if the speed fa lls back be low
the stored maximum speed.
Sett ing a threshold is recommended if you would
like to be reminded when yo u reach a certa in
maximum speed . Situations where you may want
to do so include driving in a country with a gener ­
al speed lim it or if there is a specified maximum
speed for winter tires.

::r ' Description
The predictive cont rol 1 l uses the map info rma ­
tion from the navigation system in order to react proactive ly when driving. Information from the
cam era-based traffic sign recognition * is a lso ap ­
plied to recognize traffic signs¢ page 97. When
coming up to areas wi th speed limits or changes
in the course of the road (such as curves, inter­
sections or traffic c ircles), the system brakes au ­
tomatically and then accelerates back up to the
set speed .
Overriding control
The driver can override the predict ive control at
a ny time by press ing the accelerator or brake
pedal. If the system changes the vehicle speed to
adapt to speed limits, you ca n cha nge the speed
usi ng the lever ¢page 106, fig. 100 .
Always switch off the predictive control in
the following situations:
-When increased atte ntion is needed from the
drive r.
- In poor weat her cond it ions such as snow or
heavy ra in.
- When driving on roads in poor condition .
Indicator in the instrument cluster display
When switching on the adaptive cru ise cont rol
for the first time, the message

A WARNING
-
- Read the wa rnin gs on ¢.&. in General infor­
mation on page 103 and on¢
& in De­
scription on page 97.
- Pay attent ion to traffic and the a rea around
your veh icle when pred ictive cont rol is
sw itched on. The driver is always responsi­
ble for assessing the traffic situation.
- There is an increase in the risk of an acci­
dent, because the system does not consider
"right of way" rules and also does not re ­
spond to traffic lights .
- The system only cons iders t raff ic signs that
g ive a speed lim it .
- The permitted speed can be exceeded if the
adaptation to a speed lim it is incorrect . The
d river is responsible for adher ing to the pe r­
mitte d speed .
- The s peed at w hich a curve is dr iven th rough
does not necessarily match your own driving
s tyle. Brake the vehicle yo urself whe n need­
e d t o redu ce the risk of an a ccid en t.
0) Tips
- If a speed lim it is detected, the stored
speed is also adjusted in the speedometer LE D line when the ada ptive cru ise control is
n ot a ctive .
- The adaptat ion by the system depends on
t he driving mode se t in dr ive se lec t*.
- Switching off predict ive con trol, fo r exam­
ple whe n driving in low t raff ic zones, does
101

Ass is tanc e system s
not cause the adaptive cruise control to
switc h off .
- After switching on t he ignit ion, the system
initially adj usts to a speed of 80 mph
(130 km/h) when driving onto highways
without a speed limit. Then the system ad­
justs to the last speed stored by the driver.
- There is no adaptation to speed limits when
driving thro ugh h ighway interchanges and
when driving on or off the expressway.
- There is no pred ictive control at speed limits
under 20 mph (30 km/h).
- If a speed limit is only detected by the cam ­
era and the actua l speed is significantly
higher, then the speed limit will blink in the
display u ntil you have reached the requ ired
speed

- Incorrect values from the camera-based
traffic s ign recogn ition* or outdated naviga­
tion system map data can lead to incorrect
or implausible co ntro l.
- When route guidance is switched on, the system adapts to the route provided by the
navigation system. Driving w ithout route

Audi adaptive cruise control
Description
Applies to: vehicles with Audi adaptive cruise control
Fig. 94 Detect ion ra nge
The adaptive cru ise cont rol system is a comb ina­
t ion of speed and dis tance regu lation .
It assists
t h e d river by bo th regu lating the speed and
maintain ing a d istance to the vehicle driv ing
ahead, within the limits of the system.
If the sys­
tem detects a vehicle d riving ahead, the adaptive
cruise contro l can brake and accelerate your vehi ­
cle. T his makes driving more comfortable both
o n long stretches of highway and in stop -and-go
traffic.
What can adapti ve cruise control do?
The adaptive cru ise control system uses video, ra­
dar, ultrasound and navigation data . Vehicles
driv ing ahead can be recognized up to 650 ft
(200 m) away .
Pred ictive functions offer the driver additional
comfort and contr ibute to the reduct ion in fuel
consumption and

:E ' On open roads with no traffic, it functions like a
cruise control syst em . Th e stored spe ed is main­
tained. When approach ing a veh icle driving
ahead, the adaptive c ruise control system auto­
mat ica lly brakes to mat ch that vehicle's speed
and then maintains the set distance . As soon as
the system does not detect a vehicle driving ahead, adaptive cruise contro l accelerates up to
the stored speed.
In stop -and -go traff ic, adaptive cru ise control can
brake unt il the vehicle is stat io nary and then can
also start driving again automatically under cer­
tain condi tions ¢

Which function s can be contr olled ?
When you switch adapt ive cruise control on, you
can set the current speed as the "control speed"
¢ page 104, Swi tching on/off.
When driving, you can stop c ruise contro l

In some dr iving situations, the adap tive c ruise
contro l func tion is restricte d:
- Veh icles can on ly be detected when they are
w ith in the sensor detection zones
¢ page 102,
fig. 94 .
-The system has a limited ability to detect
ve hicles that are a short dis tance ahead, off to
t he s ide of your veh icle or moving i nto yo ur
lane.
- Objects that are d ifficult to detect s uch as mo­
tor cycles, veh icles with high gro und clea rance
or an overhanging load are detected late or not
detected at all.
- When driving through curves

-W hen the veh icle is sta tionary ¢ page 104 .
A WARNING
Always pay atten tion to the traffic around you
when adaptive cru ise con trol is switched on .
As the driver, you are still responsible for your
own speed and the distance to other veh icles.
The adaptive cruise control is used to ass ist
you. The driver must always take action to
avoid a collision . The driver is always responsi ­
b le for braking at the correct time.
- For safety reasons , do not use adaptive
cru ise cont rol when the road surface is in
poor condi tion and/or in bad weather condi­
tions (such as ic e , fog, gravel, heavy rain and
hyd roplani ng) . Using the system under
these co ndi tions i ncreases the ris k of an a c­
cident.
- Sw itch adaptive cru ise cont rol off tempo ra­
r ily when dr iving in tu rning lanes, on e x­
p re ssw ay ex its (except if pre dictive control
is switched on) or in construct io n zones .
This prevents t he vehicle f rom acce le rating
to the stored speed when in these situa­
tions.
- The adaptive cruise contro l system will not
brake by itself if you put yo ur foot on the ac­
celerator pedal. Doing so can over ride the
speed and d istance regulat ion .

Assistance systems
-When approaching stationary obstacles
such as stopped traffic, adaptive cruise con­
trol will respond with limited function.
- Adaptive cruise control does not respond to
people, animals, or cross ing or oncoming
objects.
- The function of the radar sensors can be af­
fected by reflective objects such as guard
rails, the entrance to a tunnel, heavy rain or
ice.
(D Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and
underbody . Th is can impair the adaptive
cruise control. Have an authorized Audi dealer
or authorized Audi Service Facility check their
function.
