Trailer towing
Trailer towing
Driving with a trailer
General information
Your Audi was designed primarily for passenger
transportation.
If you plan to tow a trailer, please remember that
the additional load will affect durability, econo­
my and performance.
Trailer towing not on ly places more stress on the
ve hicle, it also ca lls for more concentration from
the dr iver.
F or this reason, always follow the operating and
driving instructions provided and use common
sense.
Technical requirements
Trailer hitch
Use a weight-carrying hitch conforming to the
gross tra iler weight. The hitch must be suitab le
for your veh icle and tra iler and must be mounted
securely on the vehicle's chassis at a technically
sound
locat ion . Use on ly a trailer hitch with a re­
movable ba ll mount . Always che ck with the t rail ­
er hitch man ufac tur er to make s ure t hat you are
using the co rrect hi tc h.
Do not use a bumper hitch.
The hitch must be installed in such a way that it
does not interfere with the impact -absorbing
bumper system. No mod ificat ions should be
made to the vehicle exhaust and b rake systems .
Fr om t ime to t ime, che ck that all hitch mo unti ng
bol ts rem ain securely f aste ned.
W hen you are not tow ing a tra iler, remove the
tra ile r hitc h ba ll mount . This prevents the hit ch
from caus ing damage s hou ld your veh icle be
s truck from be hind
¢ ,&. .
Trailer brakes
If you r trailer is equipped with a brak ing system,
check to be su re that it conforms to all regula­
tions .
104
The t rai ler hydraulic bra ke system must not be
directly connected to the vehicle's hydraulic
bra ke
system ¢&. .
Safety chains
Always use s afety chains be tween you r vehi cle
and t he tra ile r.
Trailer lights
Traile r lights must meet all regula tions . B e s ure
to check w ith your author ized Audi dealer for cor­
r ec t wir ing, swi tches and relays.
Mirrors
If you are unable to see t he traffic behind you us­
i ng t he regular outs ide mirrors, then yo u
must in­
stall ex tended mirrors . It is impo rtant that you
al ways have clear vision to the rear.
.&_ WARNING
Afte r remov ing the tra ile r hi tc h, do not s tore
it i n y our vehicle. In case o f su dden brak ing,
the hitch could fly fo rward and injure you or
your passengers.
Operating instructions
Maximum trailer weight
A tra iler f or yo ur vehicle is lim ite d to a typical
class 1 or class 2 trailer.
Trailer load distribution
Be sure the load in the t rai le r i s he ld se curely in
pla ce to p reve nt i t from shi fting forwar d, bac k­
ward or si deways.
Never allow a passenger to ride in a trailer ¢ &.
in Driver messages on page 105.
Engine cooling system
Towi ng a tra iler makes the engine work harder. It
is important that the cooling system's perform ­
ance is up to the additional load . Make sure tha t
the coo ling system has enoug h flu id.
Tire pressure
When towing a trailer, inflate the tires of your
vehicle to the tire p ressure listed under "Full
load" on the label

tires to trailer and tire manufacturers' specifica­
tions.
Lights
The headlight settings should be checked with
the trailer attached before driving off. Check to
make sure both vehicle and trailer lights are
working properly.
Safety chains
Be sure trailer safety chains are properly connect­
ed from the trailer to the hitch on the vehicle.
L eave enough slack in the chains to permit turn­
ing corners . When you install safety chains, make
sure they will not drag on the road when you are
driving .
The cha ins shou ld cross under the trailer tongue
to prevent it from dropping in case of separat ion
from the hitch.
Driver messages
Driving with a trailer requires extra caution.
Weight distribution
Towing a loaded trailer with an empty car results
in a high ly unstable distribution of weight .
If this
cannot be avo ided, drive at very low speeds only
to avoid the risk of losing steering control.
A "balanced" rig is easier to operate and control.
This means that the tow vehicle should be loaded to the extent possible and permissible, whi le
keep ing the trailer as light as possible under the
circumstances . Whenever possible, transfer
some cargo to the luggage compartment of the
tow vehicle whi le observ ing tongue load require­
ments and vehicle loading considerations.
Speed
The highe r the speed, the more difficult it be­
comes for the driver to control the rig. Do not
drive at the maximum permissible speed. Reduce
your speed even more if load, weather or wind conditions are unfavorable
-particularly when
going downhill.
Tra iler towing
Reduce vehicle speed immediately if the trailer
shows the slightest sign of swaying.
Do not try
to stop the swaying by accelerating.
Observe speed limits. In some areas, speeds for
vehicles towing trailers are lower than for regular
vehicles .
Always apply brakes early. When driving down­
hill, shift into a lower gear to use the engine
braking effect to slow the vehicle . Use of the
brakes alone can cause them to overheat and fail.
Coolant temperature
T he coo lant temperature gauge ~ page 11 must
be observed carefully. The coolant temperature
can increase if you drive on long inclines in a low
gear at high engine speeds . Reduce your speed
immediately if the LEDs in the top part of the dis­
play turn on.
For more information about indicator lights, re­
fer
to . ~page 30 .
A WARNING
=
Anyone not properly restrained in a moving
vehicle is at a much greater risk in an acci­
dent. Never let anyone ride in your car who is
not properly wearing the restraints provided
by Aud i.
Trailer towing
information
Important to know
-
Your vehicle handles differently when towing a
trailer because of the addit ional weight and dif­
ferent weight distribution . Safety, performance
and economy will greatly depend on how careful­
ly you load your trailer and operate you r rig.
Before you actually tow your trailer, pract ice
turning, stopping and backing up in an area away
from traffic . Keep pract ic ing until you have be­
come complete ly familiar w ith the way your vehi­
cle-trailer combination behaves and responds.

Assistance systems Electronic speed limiter
Your vehicle may be factory equipped with t ires
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
failure and loss of control if the vehicle is operat­
ed at excessive speeds, your vehicle also has an
electronic speed limiter . The electronic speed
limiter prevents your vehicle from going faster
than the t ire speed rating. For mo re information
~page 341.
If the engine control unit receives faulty vehicle
road speed s ignals, the Malfunction Indicator
L amp
(MIL) ¢..ij will illuminate. If this occurs,
contact the nearest autho rized Audi dealer for
assistance.
_& WARNING
Always observe the posted speed limits and
adjust your speed to suit prevailing road, traf­
fic and weather conditions. Never drive your
vehicle faster than the max imum speed rating
of the tires installed.
Speed warning system
Introduction
Applies 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 wa rning tone will sound as soo n as yo ur speed
exceeds the s tored value sligh tly. The
[01 (USA
models)/
[01 (Canada models) indicator light
and a message appear in the instrument cluster
display at the same time. The
HI] / [0] indicator
light and the message turn off if the speed falls
back below the stored maximum speed.
Setting a threshold is recommended if you would l ike to be reminded when yo u reach a certain
maximum speed. Situations where you may want
to do so include driving in a country with a gen er-
Ass is ta nce syst ems
al speed limit or if there is a specified maximum
speed for winter tires.

A WARNING
-~
- Always pay attention to the traffic around
you when the cruise control system is in
107

Ass is tan ce sys tems
operation. You are always responsible for
your speed and the distance between your
vehicle and other vehicles.
- For safety reasons, cruise control should not
be used in the city, in stop-and-go traffic, on
winding roads and when road condit ions are
poor (such as ice, fog, gravel, heavy rain and
hydroplaning), because th is increases the
risk of an accide nt.
- Switch the cru ise control off temporar ily
when driving in turn ing lanes, h ighway exits
o r in construction zones.
- Please note that u nconsciously "resting"
your foot on the accelerator pedal prevents
the cruise control from braking. This is be­
ca use p ressing the acce le rato r pedal
over­
rides the cruise contro l system.
- If a brake system ma lf u nction such as over­
heating occu rs when the c ruise control sys­
tem is switched on, the braking function in
the system may be switched off . The rest of
the cruise control system functions remain
act ive as long as the
tij;jl)~i# (USA models) /
ii (Canada models) indicator light is on.
(D Note
Before driving downhill a long distance on a
steep hill, decrease your speed and select a
lower gear. Th is makes use of the eng ine
braking effect and relieves the brakes.
(D Tips
- Applies to: vehicles with manual transmis­
sion: The set speed can on ly be reached if
the engaged gear permits it so that the en­
gine is not over-rewed and will run smooth­ ly. Therefore, sh ift into the higher or lower
gear in a timely manner .
- The brake lights turn on when the brakes are applied automatically.
Changing the speed

Assistance systems
Predictive control
(efficiency assist)
Description
Applies to: vehicles with Audi adaptive cruise control and pre·
dict ive efficiency assist
Fig. 122 Instrument cluster: predictive control
General information
The predictive control 1l uses the map informa·
tion from the navigation system in order to react
proactively when driving. Information from the
camera -based traffic sign recognition* is also ap·
plied to recognize traffic signs
r::!> page 109.
When coming up to areas with speed limits or
changes in the course of the road (such as curves,
inte rsections or traffic circles), the system brakes
automatically and then accelerates back up to
the set speed.
When adaptive cruise cont rol is switched off, the
system only provides notificat ions without con­
trolled intervent ions
r::!> page 112 .
The driver can override the predictive control at
any time by pressing the accelerator or brake
pedal. If the system changes the vehicle speed to
adapt to speed limits, you can ch ange the speed
using the lever
<:!> page 117 , fig . 117 .
Always switch off the predictive control in
the following situations:
- When increased attention is needed from the
driver .
- In poor we ather condit ions such as snow or
heavy rain .
- When driving on roads in poor condition.
l) This is no t a vail able in som e coun trie s.

Indicator in the instrument cluster display
When switching on the adaptive cruise control
for the first time, the message
ACC: 1111 + B ac­
tive
in the instr ument cluster indicates the avail­
ability of the predictive control.
The symbol appears when the system
i s regulating the speed to match a speed limit .
If
this is the case, the system is regulating a speed
of 50 mph (80 km/h). The speed is then taken
over by the adaptive cruise control. The speed in
the speedometer LED ring adjusts to the speed to
be maintained

A WARNING
- Read the warnings on c> .& in General infor­
mation on page 114
and on r::!> .& in Descrip­
tion an page 109 .
-Pay attention to traffic and the area around
your vehicle when predictive control 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.
