to reduce the risk of injury when the vehi­
cle is not be ing used.
- After closing the rear lid, always make
sure that it is properly closed and locked.
- Never leave your vehicle unattended es­
pecially with the rear lid left open . A
child could crawl into the vehicle through
the luggage compartment and close the
rear lid becoming trapped and unable to
get out. Be ing trapped in a vehicle can
lead to serious persona l injury.
- Never let children play in or around the vehicle .
- Never let passe ngers r ide in the luggage
compartment . Ve hicle occupants must
always be properly restrained in one of
the vehicle's seating positions.
(D Tips
- Air c irculation helps to reduce window
fogging. Sta le air escapes to the outside
th rough vents in the trim pane l. Be su re
to keep these slots free and open.
- The t ire pressure must correspond to the
load. The t ire pressur e is shown o n the
tire p ress ure label. The tire pressure la­
bel is loc ated on the d river's s ide B-pi ll a r.
The t ire pressure label lists the recom­
mended cold ti re inflat ion pressu res for
the vehicle at its maximum capacity
weig ht and the tires that were on you r
vehicle at the time it was manufactured.
For recommended t ire pressures fo r nor­
mal load conditions, please see chap ter
c:>page 199.
Tie-downs
The luggage compartment is equipped with
four tie-downs to secure luggage and other
items .
Use the tie-downs to secure your cargo prop­
erly
c:> page 100, Loading the luggage com­
partment.
In a coll is ion, the laws of phys ics mean that
even smalle r items that are loose in the vehi­
cle will become heavy missiles that can cause
Dr iving S afel y 101
serious injury. Items in the ve hicle possess en ­
ergy which vary with vehicle speed and the
weight o f the item . Vehicle speed is the most
s ignificant factor.
Fo r example, in a fronta l collision at a speed
of 30 mph (48 km/h), the forces acting on a
10 -lb (5 kg) object a re about 20 times the
no rmal weight of the item. This means that
the weight of the item would sudden ly be
about 200 lbs. (90 kg) . You can imag ine the
i njur ies that a 200 lbs . (90 kg) item flying
fr eely th ro ugh the passenger compar tme nt
c ould cause in a co lli sion like this.
A WARNING
We ak, dam aged or improper str aps used
to secure items to tie -downs can fail dur­
ing hard braking or in a collision and cause
serious personal injury .
-Always use s uita ble mount ing stra ps and
properly secu re items to the tie-downs in
the l uggage compa rtme nt to he lp pre­
vent items from shift ing or f ly ing fo r­
ward as dangerous missiles .
-When the rea r seat backrest is folded
down, a lways use suitable mounting
straps and properly secure items to the
tie-downs in the luggage compartment
to hel p prevent items from fly ing for­
ward as dangerous missiles into the pas­
s enger compartment.
- Never attach a chi ld safety seat te th er
strap to a t ie- down .

Fig. 139 Permit ted ball position of the trailer hitch
Trailer towing weights
With a factory-installed or an aftermarket
trailer hitch, the maximum permissible trailer
weight is 2,200 lbs (1,000 kg). The maximum permissible unbraked trailer weight is 1,650
lbs (750 kg) . These specifications apply when
driving on roads having an incline of less than
12%.
Permissible tongue load
For best vehicle handling under these
changed conditions, adjust the trailer load so
that the tongue load is at the maximum al­
lowable or slightly lower . You can get an ap­
proximation of the tongue load with a bath­
room 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 220 lbs
(100 kg).
It is recommended to use the maxi­
mum permissible load.
Trailer load distribution
Be sure the load in the trailer is held securely
in place to prevent it from shifting forward,
backward or sideways.
Never allow a passenger to ride in a trailer
¢.&. in Driving instructions on page 168.
Ball mount
The trailer hitch may only be used with suita­
ble ball mount and ball¢
fig. 139. Installa­
tion of the hitch ball must be carried out in ac-
Trailer towing 167
cordance with the manufacturer's instruc­
tions.
Engine cooling system
Towing a trailer 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 pressure
When towing a trailer, inflate the tires of your
vehicle 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. Inflate trailer tires to trailer and tire
manufacturers' 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 con­
nected from the trailer 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.
The 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.
To obtain the best possible handling of vehicle
and trailer, please note the following :
.,. Do not tow a loaded trailer when your car it­
self is not loaded.
.,. Be especially careful when passing other
vehicles.
.,. Observe speed limits.

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 eac h tire that
assures that a ll- important contact between
you, you r vehicle and the road.
Ma intaining 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 inspec ting t ires for damage i nclud­
ing cuts, slashes irreg ular wear and ove ra ll
condition are the most important things that
you can do to he lp avoid sudden tire failure in­
cluding tread separat ion and blowouts.
Avoiding 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 whee ls 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 .

New tires
New tires h ave 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
pa tte rn.
Hidden damage
Damage to tires and rims is ofte n not readily
visible . If you notice unusual v ib rat io n or the
vehicle p ulls 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
t horized 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 d irection 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.
For more information
¢page 223.
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
ure, including a blowout and sudden de­
fl ation, c ras hes and se riou s personal in­
juries . Have wo rn or damaged t ires re­
placed immediate ly.
- Ti res age even if they are no t being used
an d can fai l sudden ly, especially at hig h
spee ds. Tires that are more than 6 years
old can only be used in an emergency
and then w ith special care and at low
speed.

196 Tire s and wheel s
-Never mount used tires on yo ur vehicle if
yo u 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 t ire 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.

is measured or adjusted .
Curb weight
means the we ight of a motor ve hicl e w ith
standard equipment including the maximum
capac ity of fuel, oi l, and coolant, air condi­
tion ing and additional weig ht o f optiona l
equipment.
E x tra load tire
