Driving with a trailer
General information
Your Audi was designed primarily for passenger
transportation.
If you plan to tow a trai ler, please remember that
the additional load will affect durability, econo my and performance.
Trailer towing not on ly places more stress on the
vehicle, it also calls for more concentration from the driver .
F or this reason, always follow the operating and
driving instructions provided and use common
sense.
Technical requirements
Tr aile r h itch
Use a weight-carrying hitch conforming to the
gross trailer weight. The hitch must be suitable
for your vehicle and trailer and must be mounted
securely on the veh icle's chassis at a technically
sound
location . Use only a trai ler hitch w ith a re
movable bal l mount . Always check with the tra il
er h itch man ufacturer to make sure that you are
using the co rrect hitch.
D o not u se a bump er hit ch.
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 brake systems .
From time to time, check that all hitch mounting
bolts remain securely fastened .
When you are not towing a trailer, remove the
trailer h itch ball mount. This prevents the hitch
from causing damage should your vehicle be struck from behind ¢ .&, .
Trailer bra kes
If your trailer is equipped with a braking system,
check to be sure that it conforms to all regula
tions.
204
The trailer hydraulic brake system must not be di
rect ly connected to the vehicle's hydraulic brake
system ¢.&, .
Safet y ch ain s
Always use safety chains betwee n your veh icle
and the trai ler .
Tr aile r lights
Trailer lights must meet all regulations. Be sure
to check w ith your author ized Audi dealer for cor
rect w iring, sw itches, and relays .
Mirro rs
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.
&, WARNING
-If a trailer has electrical brakes p lease note
that these brakes are not activated by the
factory -fitted contro l unit -risk of accident!
- After removing the t railer hitch, do not store
it in your vehicle . In case of sudden braking,
the hitch could fly forward and injure you or
your passengers.
- Never install a "weight distributing" or "load equalizing" trailer hitch on your vehi
cle. The vehicle was not designed for these
kinds of tra iler hitches. The hitch attach
ment can fail, causing the tra iler to tear
loose from the veh icle.
- The Gross Vehicle Weight Rating for your ve
hicle, found on the safety compliance label
on the driver's side B-p illar, must never be
exceeded under any circumstances . Exceed
ing the Gross Vehicle We ight Rating of your
veh icle is likely to damage your vehicle, and
such damage will not be covered by your Limited New Vehicle Warranty. Exceeding
the Gross Vehicle Weight Rating will also
change the performance and handling char
acteristics of your vehicle, wh ich could cause
a crash resulting in serious injury or death .

Fig. 189 Pe rmi tted ba ll pos it ion of the trailer hitc h
Trailer towing weights
With a factory-installed or an aftermarket trailer
hitch, the maximum permissible trailer weight is
4,400 lbs (2,000 kg) . T he maximum permissible
unbraked trailer weight is 1,650 lbs (750 kg) .
These specifications apply when dr iv ing on roads
having an inclin e of less than 12%.
Permissible tongue load
For best vehicle handling under these changed
conditions, adjust the traile r load so that the
tongue load is at the maximum allowable or
slightly lower. You can get an approximat ion of
the tongue load w ith a bathroom scale or you can
measure the load at a trucking company or
weighing station.
With a
factory-installed or an aftermarket trailer
hitch, the maximum permissible load on the ball
hitch may not exceed 440 lbs (200 kg). It is rec
ommended to use the maximum permissible
l oad.
Trailer load distribution
Be sure the load in the tra iler is held securely in
place to prevent it from shifting forward, back
ward or sideways .
Never allow a passenger to ride in a trailer c::> .&.
in Driving instructions on page 206.
Ball mount
The trailer hitch may only be used with suitable
ball mount and ball
c::> fig. 189 . Installation of
the hitch ball must be carr ied out in accordance
with the manufacturer's instructions .
Trailer mode
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 s ure that
the cooling system has enough fluid .
Tire pressure
When towing a trailer, inflate the tires of your ve
hicle to the cold tire pressure listed under "Full
load" on the tire pressure label. The tire pressure
label is located on the driver's side B·pillar. In·
flate trailer tires to trailer and tire manufactur
ers' specifications.
Lights
T he headlight settings sho uld be checked with
the trai ler 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 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.
Driving instructions
Driving with o trailer always requires extra core
and consideration .
To obtain the best possible handling of vehicle
and trailer, please note the fo llowing :
.. Do not tow a loaded trailer when your car itse lf
is not loaded.
.. Be especially careful when passing other
vehicles .
.. Observe speed lim its .
.. Do not drive at the maximum permissible
speed.
.. Always apply brakes early .
.. Mon itor the temperature gauge .

Trailer mode
Weight distribution
Towing a loaded trai ler with an empty car res ults
in a high ly unstable distribution of weight. If this
cannot be avoided , drive at very low speeds only
to avoid the 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 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 permiss ible speed. Reduce
your speed even more if load, weathe r or wind
conditions are unfavorable - particularly 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.
Observe speed limits. In some areas, speeds for
veh icles towing trailers are lower than for regular
ve hicles .
A lways app ly brakes ear ly. When driving down
hill, shift into a lower gear to use the engine
brak ing effect to slow the vehicle. Use of the
brakes alone can cause them to overheat and fa il.
Coolant temperature
The coolant temperature gauge c::> page 10 must
be observed carefully.
If the need le moves close
to the upper end of the scale, reduce speed im
mediately and/or turn off the a ir condit ioner.
If the coo lant temperature warning light in the
instr ument cluster starts flashing •• pu ll off
the road, stop and let the engine
idle for about
two minutes to prevent heat build-up.
A WARNING
Anyone not properly restrained in a moving
vehicle is at a much greater r isk in an acc i-
206
-
dent. Never let anyone ride in your car who is
not properly wearing the restraints provided
by Audi.
Trailer mode notes
Important to know
Your vehicle handles differently when towing a
trai ler because of the additiona l weight and dif
ferent we ight distribution . Safety, performance
and economy will greatly depend on how careful
l y you load your trailer and operate your rig.
Before you actua lly tow your trai ler, practice
turning, stopping and backing up in an area away
from traffic . Keep practicing until you have be
come comp lete ly familiar with the way your vehi
cle-trailer comb inat ion behaves and responds.
Backing up is difficult and requires practice. Back
ing up with a trai ler generally requires steering
action opposite to that when backing up your ve
hicle without a tra iler.
Maintain a greater distance between your vehicle
and the one in front of you. Yo u will need more
room to stop. To compensate for the trailer, you
will need a larger than normal turn ing radius.
When passing, remember that you cannot accel
erate as fast as you norma lly wou ld because of
the added load. Make sure you have enough room
to pass. After passing, allow plenty of room for
your tra iler before changing lanes again.
Avoid jerky starts , sharp t urns or rapid lane
changes.
@ Tips
- Do not tow a trailer during the break-in peri
od of your vehicle.
- If you tow a trailer, your Audi may requi re
more frequent maintenance due to the ex
