Fig. 190 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 4,400 lbs (2,000 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 440 lbs
(200 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 214.
Ball mount
The trailer hitch may only be used with suita­
ble ball mount and ball¢
fig. 190. Installa­
tion of the hitch ball must be carried out in ac-
Trailer towing 213
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
care 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.

234 Checking and filling
-Apply the parking brake.
- Move selector lever of automatic trans- mission to P (Park).
- Always let the engine cool down. Hot components will burn skin on contact.
- To reduce the risk of being burned, never
open the hood if you see or hear steam
or coolant escaping from the engine
compartment. Wait until no steam or
coolant can be seen or heard before care­
fully opening the hood.
- Keep children away from the engine com­ partment.
- Never spill fluids on hot engine compo­
nents. They can cause a fire.
- Never touch the radiator fan. The auxili­
ary electric fan is temperature controlled
and can switch on suddenly.
- Never open the coolant reservoir cap
when the engine is still warm. The cool­
ant system is pressurized and hot cool­ ant could spray out .
- Protect your face, hands and arm from
steam or hot engine coolant by placing a
thick rag over the cap when you open the
coolant reservoir .
- Do not remove the engine cover under
any circumstances. This increases the
risk of burns.
- If work on the fuel system or the electri­
cal system is necessary:
- Always disconnect the battery.
- Never smoke or work near heaters or
open flames. Fluids in the engine com­
partment could start a fire.
- Keep an approved fire extinguisher im­
mediately available.
- To avoid electrical shock and personal in­
jury while the engine is running or being
started, never touch:
- Ignition cables
- Other components of the high voltage
electronic ignition system.
- If you must perform a check or repair
with the engine running: -
First, fully apply the parking brake,
move selector lever of automatic trans­
mission to P (Park).
- Always use extreme caution to prevent
clothing, jewelry, or long hair from get­
ting caught in the radiator fan, V-belts
or other moving parts, or from contact­ ing hot parts. Tie back hair before
starting, and do not wear clothing that
will hang or droop into the engine.
- Minimize exposure to emission and
chemical hazards

Before you check anything in the engine
compartment, always read and heed all
WARNINGS ¢&. in Working in the engine
compartment on page 233.
Engine oil
Engine oil specifications
The engine oil used in your Audi needs the
right kind of oil .
The engine in your Audi is a sophisticated
power plant that was bu ilt to exacting specifi­
cations. This eng ine needs the right k ind of
engine oil that meets specifications regarding
quality and viscosity so that it can run
smooth ly and reliab ly. Choosing the right oil
and changing oil within the time and mileage
intervals printed in your vehicle's Warranty
&
Maintenance booklet matters a lot more to­
day than it did years ago . Audi has developed
a specia l quality standard for engine oil that
will help assure that your vehicle's engine will
get the lubrication it needs for proper opera-
tion. .,..

24 2 Ch ecking and filling
-If you drain the coolant, it must be
caught and safely stored in a p roper
conta iner clearly marked "poison".
(D Note
- Coolant pollutes the env ironment and
could cause an engine fire . Excess coo l-
ant will be forced out through the pres­
sure relief valve in the cap when the en­
gine becomes hot.
- If, in an emergency, only water can be
added , the correct ratio between water
and antifreeze¢
page 240 must be re­
stored as soon as possible .
@ For the sake of the environment
Drained coolant should not be reused. Al­
ways dispose of used coolant while observ­ ing all environmental regulations.
Radiator fan
The radiator fan switches on automatically by
itself
The radiator fan is driven by the engine via the
V-be lt . The viscous clutch regulates the speed
of the fan accord ing to t he temperature of the
coolant.
An auxiliary electric radiator fan* switches on
a nd off depending on coolant temperature
and other ve hicle operating conditions.
After you switch the engine off, the auxiliary
fan can cont inue running for up to 10 minutes
- even with the ignition off. It can even switch
on again later by itself¢&. , if
- the temperature of the engine coolant rises
due to the heat build-up from the engine in
the engine compartment, or
- the engine compartment heats up because
the veh icle is parked in intense sunlight.
_&. WARNING
- To reduce the r isk of personal injury nev­
er to uch the radiator fa n. -
The a uxiliary electric fan is temperat ure
controlled and can switch on suddenly
even when the engine is not running.
- The auxiliary radiator fan switches on a u­
tomatically when the engine coolant reaches a certai n temperature and will
continue to ru n until the coolant temper­
ature drops.
Brake fluid
Checking brake fluid level
The brake fluid level can be checked with a
quick glance.

Changing brake fluid
Have the brake fluid changed by an experi­
enced technician .
Brake fluid absorbs moist ure from the a ir. If
the water con tent in the brake fluid is too
h igh, corrosion in the brake system may resul t
after a per iod of t ime . The bo iling po int of the
brake fluid w ill also decrease considerably and
decrease b raking performance .
There fore, the brake flu id must be changed
e very two years . Always use new brake fluid
which conforms to Fede ral Motor Vehicle
Standard "FMVSS 116 DOT 4 ".
The brake flu id reservoir can be difficult to
reac h, therefore , we recommend that you
h ave the brake flu id changed by your author­
iz ed
Audi dealer . Your deale r has the co rrect
too ls, the right b rake fluid and the know-how
to do this fo r you.
_& WARNING ,~
- Brake fluid is po isonous. I t must be s to r­
ed only in the closed orig inal container
o ut o f the reac h of c hildren!
- Brake fa ilure can resu lt from old o r inap ­
propriate b rake fluid. Observe these pre­
cautions :
- Use o nly bra ke fluid t hat meets SAE

256 Tire s and wheel s
-If the tire is not flat and you do not have
to change a wheel immed iately, drive at
reduced speed to the nearest service sta­
t ion to check the tire pressure and add
air as required .
(D Note
Driving without va lve stem caps can cause
damage to the t ire valves . To prevent this,
always make sure that factory installed
valve stem caps on all wheels are securely mounted on the
valve .
@) For the sake of the environment
Underinf lated tires will a lso increase the
fue l consumption .
Tires and vehicle load limits
There are limits to the amount of load or
weight that any veh icle and any t ire ca n car ry.
A vehicle that is overloaded w ill not ha ndle
well a nd is more difficult to stop. Over load ing
can not on ly lead to loss of vehicle contro l,
but can a lso damage important parts of the
ve hicle and can lead to sudden tire failure , in­
cluding a blowout and sudden deflation that
can cause the veh icle to crash .
Your safety and that of yo ur passenge rs a lso
depends on making sure that load limits are not exceeded. Vehicle load includes everybody
a nd everyth ing in and on the vehicle . T hese
load limits are tech nica lly refe rred to as the
ve hicle 's
Gross V ehicle Weight Rating
("GVWR").
The "GVWR" includes the we ight of the basic
vehicle, all factory insta lled accesso ries, a full
tank of fuel, oi l, coo la nt and othe r fluids pl us
maximum load. The maxim um load includes
the number of passengers that t he vehi cle is
intended to carry ("seating capacity") w ith an
assumed weight o f 150 lbs (6 8 kg) for each
passenger at a designated seating pos ition
and the tota l weight of any l uggage in th e
ve­
hicle. If you tow a trailer, the weight of the
trailer hitch and the tongue weig ht of the loaded tra
ile r must be included as part of the
vehicle load .
T he
Gro ss Axle Weight Rating (" GAWR") is
the max imum load th at can be applied at e ach
of the vehicle's two axles .
T he Gross Vehicle Weight Rat ing and the
G ross Ax le Weight Ra ting are listed on the
sa fety comp liance s ticke r label lo cated on the
driver's side B-pillar. Your Audi has 5 seat ing
positions, 2 in the front and 3 in the rear fo r
total seat ing capac ity of 5. Each seating posi ­
t ion has a seat be lt
c:> page 149, Safety bel ts.
The fact that there is an upper limit to yo ur
vehicle's G ross Vehicle Weight Rating means
that the total weight of whatever is being car­
ried in the vehicle ( includ ing the weight of a
tra iler hitch and the tongue weight of the
loaded tra iler) is lim ited . The more passen ­
gers in the vehicle or passenge rs w ho are
heavier than th e standard we ights assumed
mea n tha t less we ight can be carried as lug­
gage .
T he t ire pressure label on your Aud i also lis ts
the max imum combi ned weig ht of a ll of the
occupants and luggage or other cargo that
the vehi cle can carry . For t he lo ca tion of the
label <=>page 252, fig. 203.
A WARNING
Overloading a vehicle can cause loss of ve ­
hi cle cont ro l, a c rash or other accident, se­
rious personal injury, and even death.
- Ca rrying more we ight than your veh icle
was des igned to carry wi ll prevent the
veh icle from handling pr operly and in­
crease the risk of the loss of vehicle con­
trol.
- The brakes on a vehicle that has been
overloaded may not be able to stop the
veh icle w ith in a safe distance.
- Tires on a vehicle that has been overload­
ed can fail s uddenly, including a blowout
a nd sudden defla tion, causing loss of
contro l and a c rash .
~

A WARNING
Sudden tire failure can lead to loss of con­
trol, a crash and serious personal injury!
- Never drive a vehicle when the tread on
any tire is worn down to the wear indica­
tors.
- Worn tires are a safety hazard, they do
not grip well on wet roads and increase
your risk of "hydroplaning" and loss of
control.
- Always keep chemicals that can cause
tire damage, such as grease, oil, gasoline
and brake fluid away from t ires.
- Tires age even if they are not be ing used
and can fail suddenly, especially at high
speeds . Tir es that are more than 6 years
old can only be used in an emergency
and then with special care and at lower
speeds.
- Never mount used tires on your 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. Tires and wheels 259
