tra iler tires to trailer and tire manufacturers'
specif ications.
Lights
Check to make sure both vehicle and t railer lights
are working p roper ly.
Safety chains
Be sure t railer safety chains are properly connect­
ed from the trai le r to the hi tch on the veh icle.
L eave enough sla ck in the cha ins to permi t turn­
ing corners. When yo u install safety chains, ma ke
sure they wi ll not drag on the road when yo u are
driving .
The cha ins s hou ld cross under the trailer tongue

from the h itch .
Driving instructions
Driving with a trailer always requires extra care
and consideration .
To obtain t he best poss ible handling of vehicle
and traile r, please note the fo llow ing :
.,. Do not tow a loaded trailer when your car itself
is not loaded.
.. Be especi ally ca ref ul when pass ing othe r
vehicles.
.. Observe speed limi ts .
.. Do not d rive at the maximum permissible
speed.
.. Always apply brakes early.
.. Monitor the temperature gauge .
Weight distribution
Towing a loaded t railer w ith an empty car res ults
in a high ly unstable distribution of weight . If this
cannot be avoided, drive at very low speeds on ly
to avoid the risk of losing steering control.
A "balanced" rig is easie r to operate and cont rol.
This means that the tow vehi cle should be loaded
to the extent possible and permissible, while
keep ing the tra iler as light as possib le under the
circumstances. Whenever possible, transfer
some cargo to the l uggage compartment of the
128
tow veh icle wh ile observing tong ue load require ­
ments and vehicle loading considerations.
Speed
The higher the speed, the mo re diff icu lt i t be­
comes for the driver to con trol the r ig. Do not
drive at t he maxim um permissible speed. Reduce
you r speed even more if load, weather or wind
con dit ions are unfavorab le - partic ularly when
go ing downh ill.
Reduce vehicle speed
immediately if the trailer
shows the slightest sign of swaying.
Do not try
to stop the swaying by accelerating.
Observe speed limi ts. In some areas, s peeds fo r
vehicles towing trailers are lower than for regular
vehicles .
A lways apply bra kes early. Whe n driving down­
hill, shift in to a lower gea r to use the engine
b raki ng effect to slow the vehi cle. Use of the
brakes alone ca n cause them to over heat and fai l.
Coolant temperature
The coolant temperature gauge 9 page 12 must
be obse rved caref ully. The coolant temperature
c a n incre ase if yo u drive o n long incl ines in a low
gear a t high engine speeds . Red uce your speed
immediately if the LE Ds in the top part of the dis­
play turn on .

A WARNING
-
Anyone not prope rly restrai ned in a moving
vehicle is at a much greate r risk in an acci ­
dent. Never let anyone ride in your car who is
not properly wear ing the restraints provided
by Aud i.
Trailer mode notes
Important to know
Your vehicle handles differen tly when towing a
trailer because o f the additiona l weight and di f­
ferent weight distribution. Safety, performance
and economy will g reatly depend on how caref ul-
l y you load your trai ler and operate you r rig. ..,_

Electronic speed limiter
Applies to vehicles: with electronic speed limite r
Your vehicle may be factory equipped wi th tires
that are rated for a maximum speed of 130 mph (210 km/h). This is less than the maximum speed
of your vehicle. To reduce the risk of sudden tire
fa ilure and loss of control if the veh icle is operat­
ed at excessive speeds, your vehicle also has an
electron ic speed limiter. The electron ic speed
lim iter prevents your veh icle from going faster
than the t ire speed rating. For mo re information
~page 260.
If the engine control unit receives faulty vehicle
road speed s ignals, the Ma lfunction Ind icator
L amp (MIL)
¢;5 will illum inate. If this occurs,
con ta ct the nearest au thori zed A ud i d ealer for
assis tance.
A WARNING
Always observe the posted speed limits and
adjust your speed to s uit prevailing road, traf­
fic and weather cond itions. Never drive your
vehicle faster than t he maximum speed rat ing
of the tires installed.
Speed warning system
Introduction
The speed warning system helps you to stay un­
der 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 wa rning tone when your speed ex­
ceeds the stored va lue by app roxima tely 3 mph
(3 km/h). The. (U SA mode ls)/ . (Canada
models) ind ic a tor light and the message
Speed

appear in the inst rument cluste r
disp lay at the same time. The./. indicato r
light t urns off when the speed decreases be low
the stored maximum speed.
Se tting a thresho ld is recommended if you would
like to be reminded when yo u reach a certain
maximum speed. Situations where you may want
to do so include driving in a country wit h a gener-
130
al speed limit or if there is a spec ified maximum
speed for winter tires.
(D Tips
Regar dless o f th e speed war ning system, you
shou ld always monitor your spee d using the
speedometer and make s ure yo u are fo llow ing
the legal speed limit .
Setting the threshold
You can set, change and delete the threshold in
the MMI .

Cruise control system
· Description
Applies to vehicles: with cruise control system
The cru ise cont rol system ma kes it possib le to
dr ive at a constan t speed starti ng at 15 mph
(2 0 k m/h).
The speed is kep t constant by mod ifying engine
power or through an active bra ke interven tion.
A WARNING
- Always p ay att ention to the tr affi c ar ou nd
you whe n the cruise co ntro l is in opera tion.
Y ou are always responsible fo r your speed
and the distance between your veh icle and
other vehicles.
- For safety reasons, cruise cont rol should not
be used in the city, in stop-and-go traff ic, on
winding roads and when road conditions a re
poor (such as ice, fog, g ravel, heavy ra in and
hyd roplaning), because this inc reases the
ris k of an accident.
- Switch the cruise control off temporarily
when dr iv ing in turning lanes, highway exits
or in constr uct ion zones.

General information
Appl ies to vehicles: with Audi adaptive cruise contro l an d Audi
p re se nse front
Fig. 116 Front o f ve hicle: sensor
The general information applies to adaptive
cruise control* and pre sense front*¢
page 139.
The radar sensor area¢ fig. 116 must not be cov­
ered with stickers, deposits or any other obstruc­
tions as it may impair the function of the adap­
tive cruise control and the pre sense front. For in­
formation on cleaning, refer to
c:> page 2 74. The
same applies for any modifications made in the
front area .
The function of the adaptive cruise control sys­ tem and pre sense front is limited in some condi­
tions :
- Objects can only be detected when they are
within the sensor range
¢ page 132, fig. 115.
- The system has a limited ability to detect ob­
jects that are a short distance ahead, off to the side of your vehicle or moving into your lane.
- Objects that are difficult to detect such as mo ­
torcycles, vehicles with high ground clearance
or an overhanging load are detected late or not detected at all.
- When driving through curves
c:> page 134.
-With stationary objects c!;> page 134.
A WARNING
Always pay attention to traffic when adaptive
cruise control is switched on and the pre
sense front is active
c:> page 139 . As the driv­
er, you are still responsible for starting and
for maintaining speed and distance to other objects. The pre sense front is used to assist
you. The driver must always take action to
Assist
avoid a collision. The driver is always responsi­ ble for braking at the correct time.
- Using adaptive cruise control incorrectly can
cause collisions, other accidents and serious
injuries.
- For safety reasons, do not use adaptive
cruise control when driving on roads with
many curves, when the road surface is in
poor condition and/or in bad weather (such
as ice, fog, gravel, heavy rain and hydroplan­
ing) . Using the system under these condi­
tions could result in a collision.
- Switch adaptive cruise control off tempora­
rily when driving in turning lanes, on ex­
pressway exits or in construction zones. This
prevents the vehicle from accelerating to
the set speed when in these situations.
- The adaptive cruise control system will not
brake by itself if you put your foot on the ac­
celerator pedal. Doing so can override the
speed and distance regulation.
- When approaching stationary objects such
as stopped traffic, adaptive cruise control
will not respond and pre sense front will
have limited function.
- The adaptive cruise control system and pre
sense front do not react to people, animals,
objects crossing the road or oncoming ob­
jects.
- 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 .
- Always maintain enough distance from
vehicles ahead so that you can still brake
your vehicle safely . The adaptive cruise con­
trol cannot safely slow your vehicle or brake it to a stop if you are driving too close be­
hind a vehicle. Please note that the auto­
matic braking function cannot brake sud­
denly or apply the brakes fully under these
conditions.
- To reduce the risk of unintended actions,
switch the ACC off when you a re not actively
using it.

Introduction
Applies to vehicles: with Audi pre sense basic or Audi pre sense front
With in the limits of the system, p re sense basic
and pre sense front can in it iate steps to protect
vehicle occupants in certain dangerous s itua­
tions .
Critical driving situat ions can be recogn ized by
the pre sense front via a network of different ve­ hi cle systems and can take steps to prepare the
ve hicl e o ccupants for a potential collis ion.
The pre sense front works w ith a radar sensor
and a video camera*. It also functions within the limits of the system when adaptive c ruise con­

Description
Applies to vehicles: with Audi pre sense basic
The function of the pre sense basic is activated at
a speed of 20 mph (30 km/h) or h igher .
The following functions can be triggered under certain condit ions w ith in the lim its of the sys­
tem:
- Tensioning of the safety belts (for examp le,
during heavy braking): the front safety belts have reversib le be lt tens ioners. If a collision
does not occur, the safety belts loosen slightly
and are ready to tr igger aga in.
- Closing the windows and the sunroof* (for ex­
ample when over- or understeering): the win­
dows close until the re is only a small gap open
and the s unroof* closes all the way .

Audi pre sense front
Description
A pp lies to veh icles: with Audi pre sense front or Audi adapt ive

Pre sense front informs you if the distance to the
vehicle ahead falls below the safe distance for an
extended period of time.
It c an warn of a poss i­
b le co llision and initiate braki ng maneuve rs,
within the limits of the system.
When detected in time, the system can assess
dangerous s ituations where an object ahead
b rakes suddenly or if your own vehi cle is t raveling
at a high speed and approaching an object that is
mov ing more slowly. If detect ion is not possible,
then pre sense front does not react.
