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, economy 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.
@ Note
If you are going to tow a trailer, you must ac
tivate the tra ile r operation mode
¢ page 82, Operating instructions.
Technical requirements
Traile r hitch
Use a weight-carrying hitch conforming to the
gross trai ler weight. The hitch must be suitab le
for your ve hicle 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 chec k w it h t he t rail
er hitch man ufactur er to make s ure t hat you a re
using the co rrect hi tc h.
Do not use a bumper hitch.
The hitch m ust be installed i n such a way that it
does not interfere with the impact -absorbing
bumper sys tem . N o mod ificat ions should be
made to the vehicle exhaust and b rake systems .
Fr om t ime to t ime, che ck t hat all hitch mo unti ng
bol ts rem ain securely faste ned.
W hen you are not tow ing a tra iler, remove the
tra ile r hitc h ba ll mount . This prevents the hitch
from ca using damage shou ld your veh icle be
s truck from behind¢ &..

Trailer brakes
If your trailer is equipped wi th a bra king sys tem,
c h ec k t o be sure that it con forms to all regu la
tions.
The trailer hydrau lic br ake system mus t not be
directly connecte d to the vehicle's hydr auli c
brake system .
Safety chains
Always use safety chains between your vehicle
a nd t he tra ile r.
Trailer lights
Trailer lights must meet all regulations. Be sure
to check w ith your Aud i dea ler for correct wir ing,
switches and relays.
Mirrors
If you a re unab le to see the traffic behind you us
i ng the regular outs ide mir rors, then you
must in
stall extended mirrors. It is important that you
always have clear vision to the rear.
A WARNING
Afte r remov ing the tra ile r hi tch, do not s to re
i t in yo ur vehicle. In cas e of sudden brak ing,
the hit ch could fly fo rwa rd and injure you or
your pas sengers.
Operating instructions
Maximum trailer weight
A tra ile r f or yo ur vehicle is lim ite d to a typical
cla ss 1 or class 2 trailer.
Trailer load distribution
Be sure the load in the trai ler is held sec urely in
place to p revent it from shifting forward , back
ward or si deways .
Never allow a pas senger to ride in a trailer ¢ &.
in Driving instructions on page 84.
Engine cooling system
Towing a tra ile r makes the engine wor k harder . It
i s impo rtant that the cooling system's perform
ance is up to the additional load. Ma ke sure that
the cooling system has enoug h fluid.

When towing a trailer, inflate the tires of your
vehicle to the tire pressure listed under "Full
load" on the label
¢page 221. Inflate trailer
tires to trailer and tire manufacturers' specifica
tions .
Lights
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. Leave 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 chains should cross under the trailer tongue
to prevent it from dropping in case of separation
from the hitch.
Adjusting the Audi drive select
Make sure the vehicle is on a level surface before
hitching up the trailer and before adjusting the
tongue weight. The vehicle must be in
auto or
comfort driving mode and not raised
¢page 105, ¢0 .
Make sure that the vehicle is lowered. In Info
tainment , select:
ICARI function button> Lower
control button.
If you must drive under poor road conditions , you
can raise the vehicle
after coupling the trailer or
after adjusting the tongue weight ¢page 107.
0 Note
-Changes in temperature or load can affect
the height of the vehicle.
- Always select
auto or comfort mode. Other
wise, the tongue load specified for your ve
hicle will no longer be applicable.
Trailer towing
Driving instructions
Driving with a trailer always requires extra care
and consideration .
Weight distribution
Towing a loaded trailer with an empty car results
in a highly unstable distribution of weight. If this
cannot be avoided, 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 keeping the trailer as light as possible under the
circumstances . Whenever possible, transfer
some cargo to the luggage compartment of the
tow vehicle while 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 -particularly when
going downhill.
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.
Air suspension*
When driving with a trailer, activate the trailer
mode of the air suspension. Switch the air sus
pension trailer mode on when you are towing a
trailer. This will limit the regulation by the air
suspension while driving . Select in the MMI:
I CAR ! function button > (Car)* systems control
button
> Vehicle settings > Air susp.: towing >

Coolant t emperatur e
The coolant temperatu re gauge <=? page 9 must
be observed ca refully. The coo lant tempe rature
can increase if you drive on long inclines in a low
gear at high engine sp eeds. Reduce your sp eed
immed ia te ly if the LEDs in the top part of the dis
p lay turn on.
For more information abo ut indicator lights, re
fe r to . <=?
page 14.
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 Audi.

_&. WARNING
- Improper use of adaptive cruise control can
cause collis ions, other accidents and serious
personal injury .
- Never let the comfort and convenience that
adaptive cruise control and braking guard
offer d istract you from the need to be alert
to traff ic conditions and the need to rema in
in full control of your vehicle at all times,
- Always remember that the adaptive cruise
contro l and braking guard have limits - they
will not slow the veh icle down or ma intain
the set distan ce when you drive towards a n
obstacle or something on or near the road
that is not moving, such as vehicles stopped in a traffic jam, a stalled or disabled vehicle .
If registered by the radar sensors, vehicles
or obstacles that are not moving can trigger
a collision warn ing and if confirmed by the
video camera, a n acute collision warning .
- Never follow a veh icle so closely that you
cannot stop your vehicle safe ly . The adap
t ive cr uise control cannot slow or brake the
vehicle safely when you fo llow another veh i
cl e too close ly. Always remember that the
automa tic braking func tion cannot br ing the
vehicle to a sudden or emergency stop un
der these condit ions .
- T o prevent unintended operation, always
switch ACC off when it is not being used .
(U) Note
The sensors can be displaced by impacts or
damage to the bumpe r, whee l housing and
underbody. That cou ld affect t he adaptive
cruise control system and braking guard .
