manently stretched around the tether
strap . This applies especia lly to leather
seats.
Using tether straps on rearward-facing
child restraints
Cu rrently, few rear-facing child restraint sys
tems come with a tether. Please read and
heed the child restraint system manufactur
er's instructions carefully to determine how to
properly install the tether.

Trailer towing Driving with a trailer
General information
Your Audi was designed primarily for passen
ger transportation .
If you plan to tow a trailer, please remember
that the additional load will affect durability,
economy and performance .
T railer towing not only places more stress on
the vehicle, it also calls for more concentra
tion from the driver.
For 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 trailer weight. The hitch must be suita
ble for your vehicle and trailer and must be
mounted securely on the vehicle's chassis at a
technically sound location. Use only a trailer
hitch with a removable ball mount. Always
check with the trailer hitch manufacturer to
make sure that you are using the correct
hitch.
Do not use a bumper hitch.
T he hitch must be installed in such a way that
it does not interfere with the impact-absorb
ing bumper system. No modifications should
be made to the vehicle exhaust and brake sys
tems . From time to time, check that all hitch
mounting bolts remain securely fastened.
When you are not towing a trailer, remove the
trailer hitch ball mount. This prevents the
hitch from causing damage should your vehi
cle be struck from behind
¢ &. .
Trailer brakes
If your trailer is equipped with a braking sys
tem, check to be sure that it conforms to all
regulations .
Trailer towing 213
The trailer hydraulic brake system must not be
directly connected to the vehicle's hydraulic
brake system
¢ &. .
Safety chains
Always use safety chains between your vehicle
and the trailer.
Trailer lights
Trailer lights must meet all regulations . Be
sure to check with your authorized Audi dealer
for correct wiring, switches, and relays.
Mirrors
If you are unable to see the traffic behind you
using the regular outside mirrors, then you
must install extended mirrors.
It is important
that you always have clear vision to the rear .
.8, WARNING
- If a trailer has electrical brakes please
note that these brakes are not activated
by the factory-fitted control unit -risk of
accident!
- After removing the trailer 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 ve
hicle. The vehicle was not designed for
these kinds of trailer hitches . The hitch
attachment can fail, causing the trailer
to tear loose from the vehicle .
- The Gross Vehicle Weight Rating for your
vehicle, found on the safety compliance
label on the driver's side B-pillar, must
never be exceeded under any circumstan
ces. Exceeding the Gross Vehicle Weight
Rating of your vehicle 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 per
formance and handling characteristics of
your vehicle, which could cause a crash resulting in serious injury or death.

Fig. 189 Pe rmi tted ball posit ion of the tra iler h itch
T ra ile r tow ing weight s
With a factor y-insta lled or an afte rm arket
trailer h itch, the max imum permissib le trailer
weight is 4,400 lbs (2,000 kg). The maximum perm iss ible unbraked trailer weight is 1,650
lbs (750 kg). These spec ifications apply when
driving on roads hav ing an incl ine of less than
12%.
P erm is s ible tongue load
For best vehicle handling under these
changed condit ions, adjust the trailer load so
that the tongue load is at the maximum al
l owable or slightly lower . You can get an ap
p rox imation of the tongue load w ith a bath
room scale or you can measure the load at a
tr ucking company or weighing sta tion.
W ith a
fact ory -in stall ed or an aftermarket
trailer h itch, the max imum pe rm issible load
on the ball hitch may not exceed 440 lbs (200 kg).
It is recommended to use the maxi
mum permissible load .
Trailer lo ad distribut ion
Be sure the load in the trai ler is held securely
in place to prevent it from shifting fo rward,
backward or s ideways.
N eve r allow a p assenger to rid e in a trail er
¢ .&. in Driving instructions on page 215.
Ball mount
The trailer hitch may only be used with su ita
ble ball mount and ball¢
fig. 189. Installa
tion of the hitch ball must be carr ied out in ac- cordance with the manufacturer's instruc
tions.
Eng ine cooling system
T owing a t railer makes the engine work hard
er . It is important that the cooling system's
performance is up to the additional load .
Make sure that the cooling system has enough
fluid.
Tire pressur e
When towing a trailer, inflate the tires of your
vehicle to the cold tire pressu re listed under
" F u ll load" on the tire pressure label. The tire
pressure label is located on the driver's side B·
pillar. Inflate trailer tires to trailer and tire
manufacturers' spec ificat ions.
Lights
T he headlight settings shou ld be checked wi th
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 con
nected from the tra iler to the hitch on the ve
hicle . Leave enough slack in the chains to per
mit turning corners . When you install safety
chains, make sure they will not drag on the
road when you are driving.
T he chains should cross under the trailer
tongue to prevent it from dropping in case of separation from the hitch .
Driving instructions
Driving with a trailer always requires extra
core and consideration.
T o obtain the best possible handling of vehicle
and t railer, please note the fo llowing :
.,. Do not tow a loaded t railer when you r ca r it
self is not loaded .
.. Be especially caref ul when passing ot her
vehicles.
.. Observe speed limits.

~ Do not drive at the maximum permissible
speed.
~ Always apply brakes early.
~ Monitor the temperature gauge.
Weight distribution
Towing a loaded tra iler with an empty ca r re
sults 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 control.
A "balanced" rig is easier to operate and con
trol. This means that the tow vehicle should
be loaded to the extent possible and permiss i
ble, while keeping the trailer as light as possi
ble under the circumstances. Whenever possi
ble, transfer some cargo to the luggage com
partment of the tow vehicle wh ile observing
tongue load requirements 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. Re
duce your speed even more if load, weather or
wind conditions are unfavorable -part icularly
when going downhill.
Reduce vehicle speed
immediately if the trail
er shows the slightest 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 vehicles.
Always apply brakes early . When driving
downhill, shift into a lower gear to use the en
g ine braking effect to slow the vehicle . Use of
the brakes alone can cause them to ove rheat
and fail.
Coolant temperature
T he coolant temperature gauge c:> page 10
must be observed carefully . If the needle
moves close to the upper end of the scale, re
duce speed immed iate ly and/or turn off the
air cond itioner.
Trailertowin g 215
If the coolant temperature warning light in
the instr ument cluster starts flashing., pull
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 mov
ing vehicle is at a much greater risk in an
accident. Never let anyone ride in your car
who is not properly wearing the restraints
prov ided by Audi .
Trailer towing tips
Important to know
Your vehicle handles differently when towing
-
a trailer because of the additional weight and
different weight distr ibut ion. Safety, perform
ance and economy will greatly depend on how
carefully you load your trailer and operate
your rig.
Before you actually tow your tra iler, practice
turning, stopping and backing up in an area
away from traffic. Keep practicing until you
have become completely familiar w ith the way
your vehicle-tra ile r combination behaves and
responds.
Backing up is difficult and requires practice .
Backing up with a trailer generally requires
steering action opposite to that when backing
u p you r vehicle without a trailer.
Maintain a greater d ista nce between your ve
hicle and the one in front of you. You w ill need
more room to stop. To compensate fo r the
trailer, you w ill need a larger than normal
turning radius.
When passing, remember that you cannot ac
celerate as fast as you normally would be
cause of the added load. Make sure yo u have
enough room to pass. After passing, a llow
plenty of room for your trailer before chang
ing lanes again.
Avoid jerky starts , sharp t urns or rapid lane
changes.

Tires and wheels
Tires
General notes
Tires may be the least appreciated and most
abused parts of a motor vehicle .
Tires may be the least appreciated and most
abused parts of a motor vehicle . Tires are,
however, one of the most important parts of a
vehicle, particularly considering the compara
tively small patch of rubber on each tire that
assures that a ll- important contact between
you, your vehicle and the road.
Maintaining the correct tire pressure, mak ing
sure that your vehicle and its tires do not have
to carry mo re weight than they can safely han
d le, avoiding damage from road hazards and
r eg ularly inspect ing t ires for damage i nclud
ing cuts, slashes irregu la r wear and ove rall
condition are the most important things that
you can do to he lp avoid sudden tire failure in
cluding tread separat ion and blowouts.
A voidin g damage
If you have to d rive over a curb or similar ob
stacle, drive very slow ly and as close as possi
b le at a right angle to the curb.
A lways keep chemicals includ ing grease, o il ,
gasoline and brake fluid off the t ires .
I nspect the t ires regularly for damage (cuts,
cracks or b listers, etc.). Remove any fo reign
bod ies embedde d in the treads.
Storing tires Mark tires when you remove them to indicate
the direction of rotation . T his ensures you to
be ab le to mount them correctly when you re
i nstall them .
When removed, the wheels or t ires should be
sto red in a cool, d ry and preferably dark place .
Store tires in a vertical pos ition if they are not
mounted on rims, in a horizontal pos it ion if
they are mounted on rims .
Tires an d wheel s 24 7
New tires
New ti res have to be broken in¢& .
The tread depth of new t ires may vary, accord
ing to the type a nd make of t ire and the tread
patte rn.
H idden damage
Damage to tires and r ims is ofte n not readily
visible . If you notice unusual v ib rat ion or the
vehicle pulls to one s ide, th is may ind icate
that one of the t ires has been damaged . T he
ti res m ust be chec ked immed iate ly by an au
thorized Audi dea le r or q ua lified wor kshop .
Unidirectional tires
A un idirectional tire can be identified by ar
rows on the sidewa ll, that po int in the direc
tion the t ire is designed to rotate. You mus t
f ol low the specified di rection o f rotation . T his
is necessary so that these tires can develop
their optimum characteristics regarding grip, road noise, wear and hydrop laning resistance.

A WARNING
New tires or t ires that are o ld, worn or
damaged cannot provide maximum con
trol and braking ability .
-
-New tires tend to be slippery and must
also be b roken-in. To reduce the risk of
losing control, a collision and serious
pe rsonal injuries, drive w it h special care
for the first 350 miles (560 km).
- Driving with worn or damaged tires can
lead to loss of control, sudden tire fail

248 Tire s and whee ls
- Never mount used tires on yo ur vehicle if
you are not sure of their "previous histo
ry." Old used tires may have been dam
aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss of vehicle control.
- If you notice unusual vibration or if the
vehicle pulls to one side when driving, al
ways stop as soon as it is safe to do so and check the wheels and tires for dam
age.
