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.
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 .
90
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 91.
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 fluid.
Tire pressure
When towing a trailer, inflate the tires of your
vehicle to the cold tire p ressure listed under "Full
load" on the t ire press ure label. The t ire pressure
1111-

label is located on the driver's side B-pillar. In­
f late trai ler tires to trailer and tire manufactur­
ers' specifications.
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 tra iler 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 wi ll not drag on the road when you are
driving.
The chains shou ld cross under the trailer tongue
to prevent it from dropping in case of separation
from the hitch.
Driver messages
Driving with a trailer requires extra caution .
Weight distribution
Towing a loaded trailer w ith an empty car results
in a high ly unstable dist ribution 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 cont rol.
This means that the tow vehicle should be loaded
to the extent possible and permissible, while
keeping th e trailer as light as possib le under the
circumstances . Whenever possib le, transfer
some cargo to the luggage compartment of the
tow vehicle whi le observing tong ue load require­
ments and vehicle loading considerations.
Speed
The higher the speed, the more difficult it be­
comes for the driver to contro l 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 a,
;::; going downhill. ,....

3 a,
Trailer 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 eng ine
braking effect to slow the vehicle . Use of the
brakes alone can cause them to overheat and fail.
Coolant temperature
T he coolant temperature gauge~ page 11 must
be obse rved 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 31 .
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.
91

Trailer towing
Backing up is difficult and requires practice .
Backing up with a trailer generally requires steer­
ing action oppos ite to that when backing up your
veh icle w ithout a trailer .
Maintain a g reater distance between your vehicle
and the one in front of you. You w ill need more
room to stop. To compensate for the tra iler, you
will need a larger than normal turn ing radius.
When passing, remember that you cannot accel ­
erate as fast as you norma lly would because of
the added load. Make sure you have enough room
to pass. After passing, allow plenty of room for
your tra iler before chang ing lanes again .
Avoid jerky starts , sharp turns or rapid lane
changes .
@ Tips
- Do not tow a trailer during the break -in per i­
od of your vehicle.
- If you tow a trailer, your Audi may require
more frequent maintenance d ue to the ex ­
tra load
~ page 363.
Parking on a slope
Do not pork on a slope with a trailer. If it cannot
be avoided, do so only o~er doing the following:
When parking:
.. Apply t he foo t brake .
.. Have someone place chocks under both t he ve­
hicle and the tra ile r whee ls .
.. With chocks in p lace, slowly release t he brakes
u ntil the whee l chocks absorb the load .
.. Turn the wheels towards the curb .
.. Apply the parking brake .
.. Move the selector lever to P .
When restarting after pa rking:
.. Apply the foot brake .
.. Start the engine .
.. Move the selector lever to D/S .
.. Release the parking brake and slowly pull out
and away from the wheel chocks .
.. Stop and have someone retrieve t he wheel
chocks .
