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
.,,.
