"' " "' .... 0 0 :r Trailer mode Driving with a trailer
Gen eral 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 .
T ra iler towing not only p laces more stress on the
vehicle, it a lso calls for more concentration from
the driver.
For this reason, always follow the operating and
driving instr uctions provided and use common
sense.
(D Note
If you are going to tow a trailer, you must ac­
tivate the tra iler operation mode
<=> page 89, Operating instructions.
Technical requirements
Tr ailer hitch
Use a weight-carrying hitch conforming to the
gross tra iler weight. The h itch must be suitab le
for your vehicle and tra iler and must be mounted
securely on the vehicle's chassis at a
technically
sound
location . Use on ly a trailer hitch with a re­
movable ba ll mount . Always chec k w ith the t rail­
er hitch manufac turer to make sure that you are
using the correct hitch .
Do not u se 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 ifications should be
made to the vehicle exhaust and b rake systems .
Fr om t ime to t ime, check that al l hitch mo un ting
bol ts rem ain securely fastened.
When you are not towing a trailer, remove the tra iler hi tch ba ll mount . This preven ts the hitch
from causing damage shou ld your vehicle be
struck from beh ind
C? _&. .
Tr ailer mod e
Trailer brakes
If your trai ler is equ ipped with a b raking system,
check to be sure that it conforms to a ll regu la ­
tions.
T he trai ler hydra ulic bra ke sys tem must not be
directly connected to the vehicle's hydra ulic
brake system.
Safety chains
Always use safety chains between your vehicle and the tra iler .
Tra iler lights
Trailer lights must meet all regulations. Be sure
to check w ith your Audi dealer for correct wir ing,
switches and relays .
Mirror s
If you are unable to see the traffic behind you us­
ing the regular outside mirrors, 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 hitch, do not sto re
i t in you r vehicle. In case of sudden brak ing,
t he hitch could fly fo rward and inju re you or
your passengers.

Trailer mode
Trailer load distribution
Be s ure the load in the trailer is held securely in
p lace to prevent it from shifting forward, back­
ward or sideways .
Never allow a passenger to ride in a trailer¢.&.
in Driving instructions on page 91.
Engine cooling system
Towing a trailer makes the eng ine 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 eno ugh fluid.
Tire pressure
When tow ing a tra iler, inflate the tires of your
veh icle to the tire pressure listed under "Full
load " on the label ¢
page 293 . Inflate trailer
tires to trailer and tir e 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 cha ins, make
sure they w ill 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 adjust ing the
tongue weight. The vehicle must be in
auto or
comfort driving mode and not raised
o:,;, page 110, o:,;, 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 adjust ing the tongue we ight ¢ page 112.
([) 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 app licab le .
Driving instructions
Driving with a trailer always requires extra care
and consideration.
Weight distribution
Towing a loaded trailer with an empty car results
i n a high ly unstable distribution of we ight . If this
cannot be avoided, drive at very low speeds only
to avoid t he risk of losing steering contro l.
A "balanced " rig is easier to operate and control.
This means that the tow vehicle should be loaded
to the extent possible and permissib le, wh ile
keeping the trailer as light as possible under the
circumstances. Whenever possible, transfer
some cargo to the luggage compartment of the
tow veh icle 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 cond it ions are unfavorable - particularly when
go ing downh ill.
Reduce vehicle speed
immediately if the trailer
shows the slightest sign of sway ing.
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. ..,.

0 co .... N ,..._
N .... 0 0 :c ' Air suspension*
When driv ing 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:
ICARI function button > (Ca r)* systems control
button
> Vehicle settings > Air susp.: towing >
On.
Coolant temperature
The coolant temperature gauge¢ page 9 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
i mmed iately if the LEDs in the top part of the dis­
p lay turn on.

A WARNING
Anyone not properly restrained in a moving
vehicle is at a much greater risk in an acci­
de nt. Never let anyone ride in you r car who is
not properly wearing the restraints p rovided
by Audi.
Trailer mode notes
Important to know -
Your veh
icle handles differently when tow ing a
tra iler because of the additional weight and d if ­
ferent weight distr ibut ion. Safety, performance
and economy will greatly depend on how careful­
ly yo u load you r trailer and operate your rig.
Before you actually tow your trailer, practice
turning, stopp ing and back ing up in a n area away
from traffic. Keep practicing until you have be­
come completely fami liar with the way your vehi­
cle-trailer comb inat io n behaves and responds.
Backing up is difficult and requires pract ice.
Backing up with a trailer gene rally requires steer­
ing action opposite to tha t when backing up your
ve hicl e without a trailer .
Maintain a greater d istance between your vehicle
and the one in front of you . You w ill need more
Trailer mode
room to stop . To compensate for the trailer, you
will need a larger than normal turning radius .
When passing, remember that you cannot accel­
erate as fast as you normally wo uld because of
the added load. Make sure you have enough room
to pass. After passing, allow p lenty of room for
your trailer before changing lanes again .
Avo id jerky starts, sharp turns or rapid lane
changes.
(D Tips
- Do not tow a trailer during the break-in peri­
od of your veh icle.
-If you tow a trailer, your Audi may requ ire
more frequent maintenance due to the ex­
tra load ¢

Parking on a slope
Do not park on a slope with a trailer. If it cannot
be avoided, do so only after doing the following:
When parking:
" Apply the foot brake .
" Have someone place chocks under both the ve­
hicle and the trailer wheels.
"W ith chocks in place, slowly release the brakes
until the wheel chocks absorb the load.
" Tur n the whee ls towards the curb.
" App ly the parking brake.
" Select the P selector lever position.
When restarting after parking:
"App ly the foot brake.
" Start the engine .
"S elect the D selector lever position .
" Release the parking brake and slowly pull out
and away from the wheel chocks.
" Stop and have someone retrieve the wheel
chocks.
(D Tips
If you move the selector lever of the automat­
i c transmission to P before applying the park­
in g brake and before blocking the wheels, you
may have to use more force later to move the
lever out of the P posit ion.
