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 100.
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
and t he tra ile r.
Trailer lights
Trailer lights must meet all regulations. Be sure
to check w ith your author ized Audi dealer for cor­
r ect wir ing , sw itches and relays .
Mirrors
If you are unab le to see the traffic behind you us­
i ng the regular outs ide mirrors, then you
must in­
stall extended mirro rs. It is important that you
always have clear vision to the rear.
A WARNING

Operating instructions
Trailer towing weights
The maximum permissible unbraked trailer
weight is 1,650 lbs (750 kg) .
The maximum permissible braked trailer weight
is:
- Q7 2.0: 5,500 lbs (2,500 kg)
- Q7 3 .0: 7,700 lbs (3,500 kg)
These specifications apply when driving on roads having an incline of less than 12% .
Permissible tongue load
For best vehicle handling under these changed
conditions, adjust the trailer load so that the
tongue load is at the maximum allowable or
slightly lower . You can get an approximation of
the tongue load with a bathroom scale or you can
measure the load at a trucking company or
weighing station.
The maximum permissible load on the ball hitch may not exceed:
- Q7 2.0: 550 lbs (250 kg)
- Q7 3 .0: 770 lbs (350 kg)
It is recommended to use the maximum permis­
sible load. Please also observe the information
¢page 343, ¢page 347.
Trailer load distribution
Be sure the load in the trailer is held securely in
place to prevent it from shifting forward, back­
ward or sideways.
Never allow a passenger to ride in a trailer¢.&.

Ball mount
The trailer hitch may only be used with suitable ball mount and ball. Installation of the hitch ball
must be carried out in accordance with the manu­
facturer's instructions .
Trailer towing
Engine cooling system
Towing a trailer makes the engine work harder. It
is important that the cooling system's perform­
ance is up to the additional load. Make sure that
the cooling system has enough fluid.
Tire pressure
When towing a trailer, inflate the tires of your
vehicle to the tire pressure listed under "Full
load" on the label <:!;>
page 343. Inflate trailer
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 .
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.
Setting drive select(air suspension)*
Make sure the vehicle is on a level surface before
hitching the trailer and before adjusting the
tongue weight. The driving mode must be in
Au­
to or Comfort ¢page 134, ¢ (D
If you would like to drive in the Dynamic driving
mode, then you must select this mode before
hitching the trailer and before adjusting the
tongue weight. Please note that your vehicle will
lower and the ground clearance is reduced.
If you have to drive through difficult road condi­
tions, you can raise the vehicle again after hitch­
ing the trailer or after adjusting the tongue
weight

Messages
Driving with a trailer requires extra caution .
Weight distribution
Towing a loaded trailer with an empty car res ults
i n a hig hly unstable dist ribution of weight. If this
cannot be avo ided, drive at ve ry low speeds o nly
to avoid the risk of lo sing s teeri ng con trol.
A "balanced" rig is eas ie r to operate and cont rol.
T his means that the tow veh icle should be loaded
to the exte nt poss ible a nd permiss ible , while
keep ing the tra ile r as lig ht as possib le unde r th e
circumstances . Whenever possible, transfer
some cargo to the l uggage compa rtment of the
tow vehicle whi le observ ing tongue load req uire­
ments and ve hicle loading considerat ions.
Speed
T he higher the spee d, the more d ifficult i t be­
comes for the drive r to co ntro l the rig. Do not
drive at the maximum permissible speed. Reduce
your speed even more if load, weather or w ind
conditions a re unfavorable -part icularly when
going downhill.
Re du ce veh icle spee d
immediately if the trai le r
shows the s lightest sign o f swaying.
Do not try
to stop the sway ing by accele rating .
Observe speed lim its. In some areas, speeds for
ve hicles towing trai lers are lower than for reg ular
veh icles.
A lways app ly b rakes early. When dr iv ing down ­
hi ll, shift into a lower gear to use the engine
braking effect to slow the veh icle. Use of the
brakes a lone can cause them to ove rheat and fail.
Air suspension*
If you are connecting a trailer to a fa cto ry -ins tal­
led trai ler hitch, trai ler mode a utomat ic all y
switches on in the ai r suspensio n. This will limit
the reg ulation by the a ir s usp ension whi le dr iv -

ing . If you want to swi tch off tra iler mode wh ile
driving, for example when using a bicycle rack system, se lect in the Infota inment system :
IM ENUI button> Vehicle > left control button>
Vehicle settings > Air suspension: trailer .
If the vehicle has a retrofitte d tra iler hitc h, the
trailer mo de might not switch on automatically .
In this case, switch the tra iler mode on before
hitc hing the tra iler and switch it off after un­
hitc hing the tra ile r.
Coolant tempe rature
