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
tra load

Parking on a slope
Do not pork on a slope with a trailer. If it cannot
be avoided, do so only ofter doing the following:
When parking:
.. Apply the foot brake .
.. Have someone place chocks under both the ve­
hicle and the trailer wheels .
.. With chocks in p lace, slowly re lease the brakes
unt il the w heel chocks absorb the load .
.. Turn the wheels towa rds the curb .
.. Apply the pa rking bra ke .
.. Move the selec tor lever to P .
When restarting after parking:
.. Apply the foot brake .
.. Start the eng ine .
.. Move the se lecto r lever to 0/5 .
.,. Re lease the par king b rake a nd slow ly pull ou t
and away from the whee l cho cks .
.. Stop and have someone re trieve the w heel
chocks .
(D Tips
If you move the selector lever of the a utomat­
ic transmission to P before applying the par k­
ing brake and before blocking the wheels, you
may have to use more force later to move the
lever out of the P position .

wash operator to reduce the risk of acci­
dents.
- To reduce the risk of cuts, protect yourself
from sharp metal components when wash­
ing the underbody or the inside of the wheel
housings.
- After washing the vehicle, the braking effect
may be delayed due to moisture on the
brake rotors or ice in the w inter. The brakes
must be dried first w ith a few careful brake
applications.
- If you wash the vehicle in an automatic car
wash, you must fold the exterior m irrors in
to reduce the risk of damage to the mirrors.
Power folding exterior mirrors* must only
be fo lded in and out us ing the power folding
funct ion.
- To reduce the risk of damage to the rims
and tires, compare the width between the
whee ls on your vehicle w ith the distance be­
tween the g uide rails in the car wash .
- To red uce the risk of damage, compare the
height and width of yo ur vehicle with the

- T o prevent paint damage, do not wash the
vehicle in direct sunlight.
- To reduce the ris k of damage to the sur face,
do not use insect remov ing sponges, kitchen
sponges o r similar items.
- Matte finish painted veh icle components:
- To reduce the risk of damage to the sur-
face, do not use polishing agents or hard
wax.
- Never use protective wax. It can destroy
the matte finish effect.
- Do not place any stickers or magnetic
signs on vehicle parts painted w ith matte
finish paint. The paint could be damaged
when the stickers or magnets are re­ moved.
@ For the sake of the environment
Only wash the vehicle in facilities spec ially de­
s igned for that purpose. Th is w ill reduce the
r isk of dirty water contaminated w ith oil from

Wheels
passengers that the vehicle is in­
tended to carry ("seating capaci­
ty") with an assumed weight of 150 lbs. (68 kg) for each passen­
ger at a designated seating posi­
tion and the total weight of any
luggage in the vehicle. If you tow
a trailer, the weight of the trailer
hitch and the tongue weight of
the loaded trailer must be includ­
ed as part of the vehicle load.
The
Gross Axle Weight Rating
("GAWR") is the maximum load
that can be applied at each of the
vehicle's two axles.
The fact that there is an upper limit to your vehicle's Gross Vehi­
cle Weight Rating means that the
total weight of whatever is being
carried in the vehicle (including
the weight of a trailer hitch and
the tongue weight of the loaded
trailer) is limited. The more pas­
sengers in the vehicle or passen­
gers who are heavier than the
standard weights assumed mean
that less weight can be carried as
luggage.
The Gross Vehicle Weight Rating
and the Gross Axle Weight Rating
are listed on the safety compli­
ance sticker label located on the
248
driver's side B-pillar ~ page 245,
fig. 206.
~ WARNING
Overloading a vehicle can cause
loss of vehicle control, a crash
or other accident, serious per­
sonal injury, and even death.
-Carrying more weight than your vehicle was designed to carry will prevent the vehicle
from handling properly and in­
crease the risk of the loss of
vehicle control.
-The brakes on a vehicle that
has been overloaded may not
be able to stop the vehicle
within a safe distance.
-Tires on a vehicle that has
been overloaded can fail sud­
denly, including a blowout and
sudden deflation, causing loss
of control and a crash.
-A lways make sure that the to­
tal load being transported -
including the weight of a trail­
er hitch and the tongue
weight of a loaded trailer -
does not make the vehicle
heavier than the vehicle's
Gross Vehicle Weight Rating.
