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 tha t 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
c> ,&. .
Trailer brakes
If your trailer is equipped with a brak ing system,
check to be su re that it conforms to all regula­
tions .
120
The t rai ler hydraulic bra ke system must not be
directly connected to the vehicle's hydraulic
bra ke system.
Safety chains
A lways use s afety chains between 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 Aud i dea le r fo r cor rect wir ing,
switches and relays .
Mirrors
If you are unable to see t he traffic behind you us­
i ng t he regular outs ide mir rors, then yo u
must in­
stall extended mirro rs . It is impo rtant that you
always have clear vision to the rear.
&, WARNING
Afte r remov ing the tr ailer hi tch, do not s to re
i t i n yo ur vehicle. In case o f su d den braking,
the hitch could fly fo rwa rd 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 revent i t from shi fting forward, bac k­
ward or si deways.
Never allow a passenger to ride in a trailer c> &.
in Driving instructions on page 121.
Engine cooling system
Towing 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, inf late the tires of your
vehicle to the tire pressure listed under "Full load" on the label
c> page 336. Inflate trailer

CXl CXl .... N ,.__
N .... 0 N > 00
tires to trailer and tire manufacturers' specifica­
tions.
Lights
Check to make sure both vehicle and trailer lights
are working p roperly.
Safety chains
Be sure trailer safety chains are properly connect ­
ed from the tra iler to the hitch on the vehicle.
Leave enough slack in the chains to permit turn­
in g corners . When you install safety cha ins, ma ke
sure they w ill not drag on the road when yo u are
driving .
The chains shou ld cross under the trailer tongue
to prevent it from dropping in case of separat ion
from the hitch.
Driving instructions
Driving with a trailer always requires extra care
and consideration.
Weight distribution
Towing a loaded trailer w ith an empty car results
in a highly 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, while
keep ing the tra iler as light as possib le under the
circumstances. Whenever possib le, t ransfer
some cargo to the luggage compartment of the
tow vehicle whi le observing tongue load require­
ments and vehicle loading considerations .
Speed
The higher 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
-particu larly when
going downhill.
Reduce vehicle speed
immediately if the trailer
shows the s lightest sign of swaying .
Do not try
to stop the swaying by accelerating.
Tra iler towing
Observe speed limits. In some a reas, 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 fa il.
Coolant temperature
T he coo lant tempe rature 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 28.
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 g reatly depend on how careful­
ly you load your trailer and operate yo ur rig.
Before you actually tow your trailer, pract ice
turning, stopping and backing up in an area away
from traffic. Keep practic ing until you have be­
come complete ly familiar w ith the way your vehi­
cle-trailer combination behaves and responds.
Backing up is difficult and requires practice.
Backing up with a t railer genera lly requires steer ­
i ng action opposite to that when backing up your
vehicle without a tra iler.
Maintain a greater distance between your vehicle
and the one in front of you. You will need more
.,,.

Assistance systems Electronic speed limiter
Applies to: vehicles with electronic speed lim iter
Your vehicle may be factory equipped with 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
failure and loss of control if the vehicle is operat­
ed at excessive speeds, your vehicle also has an
electronic speed lim iter . The electronic speed
limiter prevents your vehicle from going faster
than the tir e speed rating. For more information
¢page 335.
If the engine control unit receives faulty vehicle
road speed s ignals, the Malfunction Indicator
L amp (MIL)
II! will illuminate . If this occurs,
contact the nearest authorized 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 rat ing
of the tires installed.
Speed warning system
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 warning tone will sound as soon as your speed
exceeds the stored value slightly . The
101 (USA
models) /
[01 (Canada mode ls) indicator light
and the corresponding message appear in the in ­
strument cluster display at the same time. The
[OJ (USA models)/ (•j (Canada models) indicato r
light and the message turn
off when the vehicle
speed drops 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 gener-

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
r isk of an accident.
- Switch the cruise control off temporar ily
when driving in turn ing lanes, h ighway exits
or in construction zones.
- Please note that unconsciously "resting" yo ur foot on the accelerator pedal prevents
the cruise control from braking. This is be­
ca use p ressing the acce le rato r pedal ove r­
rides the c ruise contro l system.
- If a bra ke system ma lf u nction such as over­
heating occu rs when the c ruise contro l sys­

Audi pre sense
Introduction
Appl ies to : vehicles wit h Aud i pre sense
Within t he limits of the system, the pre sense
f unct ions can initiate measures in pa rtic ularly
dange rous situations to protect the vehicle pas-
sengers and other road users.
..,.
133

Assistance systems
-Due to the interlinking of various vehicle sys­
tems, critica l driving situations can be detected
by
pre sense basic and measures for preventa­
tive occupant protection are can be initiated.
-The pre sense front uses the data from the ra­
dar sensors and calcu lates the probability of an
accident
c> page 127. An impending collision
with vehicles can be detected within the limits
of the system . In this case, the system warns
the driver visually, acoustically and with a jerk
on the brakes if necessary. If needed, it can i ni­
tiate a partia l or full dece le rat ion to reduce the
collision speed o r to avoid the coll ision unde r
ce rtain c ircumstances. In conjunction with pre
sense basic, the front safety belts are also re­
versib ly tensioned when needed . The pre sense
front is also active when adaptive cruise con­
trol* is sw itched off.
.,&. WARNING
Also follow the general instructions found in
c> .&. in General information on page 127.
(i) Tips
-Certain pre sense functions switch off when
driving in reverse.
-The pre sense functions may not be availa­ ble if there is a malfunction in the ESC sys­
tem or the airbag contro l module.
-Note that the reversible belt tensioner on
the front passenger's side deactivates when
the front passenger's a irbag is deactivated .
-Switch the pre sense off when you are not
us ing public streets or when loading the ve­
hicle onto a vehicle carr ier, train, ship or
other type of transportation. This can pre­
vent an undes ired intervention from the pre
sense system.
