& WARNING
-Always observe the wa rning in
¢
page 179, before opening the hood
and checking the engine coolant level.
- Never open the engine hood if you see or
hear steam, or if you see engine coolant
dripping from the engine compartment.
You could burn yourself. Let the engine cool off first so that you cannot hear or
see any steam or engine coolant.
(D Note
- Mounting additional lights or accessories
in front of the air inlets reduces the cool­
i ng effect of the rad iator. At h igh outside
temperatures or high eng ine load, the
engine could overheat.
- The front spo iler has been designed to
proper ly distr ib ute the cooling air when
the veh icle is moving.
If the spoiler is
damaged, this cou ld redu ce the cooling
effect and the engine co uld then over­
heat. Ask yo ur autho rized Aud i de aler f or
assistance.
Tachometer (engine rev counter)
The tachometer indicates the engine RPM
(revolutions per minutes).
If engine R PM drops be low 1,500, you should
downshift to the next lower gear. The red area
at the e nd of the sca le ind icates maximum
permissible engine RPM after the break- in pe­
riod. Before reaching this area, move these­
l ector lever to position D/S or ease your foot
off the accelerator peda l.
(D Note
The tachometer needle@¢ page 10,
fig. 3 sho uld only briefly be in the red
zone: you could damage your engine! The
beg inning of the red zone varies depend­
ing on the engine.
@) For the sake of the environment

ately contact your authorized Audi dealer or
qua lified workshop to have all brake pads in­
spected
¢ page 17.
When the light comes on, an audib le warning
signal is also given .
.&_ WARNING
- Always observe the warnings in
¢ page 179, before opening the hood
and checking the brake fluid.
- Driv ing with low brake fluid is a safety
hazard. Stop the car and get professional
assistance.
- If the . (USA models) . (Canada
models) brake system indicator light
turns on together with the ABS and ESC
indicator lights, the ABS/ESC regu lating
function may have failed. Functions that
stabilize the vehicle are no longer availa­
ble. Th is could cause the vehicle to
swerve and increase the risk of sliding .
Drive carefully to the nearest a uthorized
Audi dealer or other qualified workshop
and have the malfunction corrected.
- If the brake warning/indicator light does
not go out after a few seconds and the
park ing brake is released, or lights up
wh ile you are driving, the fluid level in
the brake fluid reservoir is too low .
If you
believe that it is safe to do so, proceed
immediately at low speed to the nearest
authori zed Audi dealer o r qualified wo rk­
shop and have the bra ke system inspect­
ed.
- Always keep in m ind that after several
brake applicat ions, yo u will need greater
pressure on the brake peda l to stop your
vehicle. Do not re ly on strained brakes to
respond with maxim um stopping power
in critical situations. You must allow for
increased brak ing distances. The extra
distance used up by fad ing brakes could
lead to an acc ident.
PARK !<®> Electromechanical parking brake

Warm and cold Climate control
Description
The climate control system warms, cools and
adds humidity to the a ir in the veh icle inter io r.
It is the most effect ive when the windows and
sunroof are closed . If the re is a build-up of
h eat inside the vehicle, ventilation can help to
speed up the cooling process .
Condensat ion from the cooling sys tem can
drip and form a puddle of water under the ve­
hicle. This is normal and does not mean there
is a leak .
Pollution filter
The po llution filte r removes impuri ties, such
as dus t and po llen, from the air.
The air pollutants filter must be changed at
the intervals spec ified in you r Wa rra nty
&
M aintenance book let, so tha t the air condi­
tioner can prope rly work .
If you drive your vehicle in an area with h igh
a ir po llution, the fi lter may need to be
changed more frequent ly than specified in
your Aud i Warr anty
& Ma intenance booklet. If
in doubt, ask your authorized A udi Service Ad ­
visor for advice .
A WARNING
Reduced visibility is dangero us and can
cause accidents.
-
- For safe dr iv ing it is very important that
all windows be free of ice, snow and con­
densation.
Warm and c old 63
-Comp letely fam iliarize yourse lf with the
proper use and f unct ion of the heat ing
a nd venti lation system and especially
how to defog and defrost the w indows.
- Never use the windshield wiper/washer
system in freez ing weather unt il you
have warmed the w indshield first, using
the heating and ve ntilation system. The
washer sol ution may freeze on the wi nd­
shie ld and re duce visib ility.
0 Note
- If you suspect that the air conditioner
has been damaged, switch t he system
off to avoid furt her damage and have it
in spec ted by a q ual ified dea lership.
- Repairs to the Audi air conditioner re­
quire specia l te ch nical know ledge and
speci al to ols. Conta ct an autho rized Aud i
dea ler fo r ass istance.
(® For the sake of the environment
B y reducing the a mou nt of f uel you use,
you also reduce the amount of pollu tants
emitted in to the air.
(D Tips
- Keep the air intake s lots ( in fro nt of the
w indshield) free from ice, snow and de­
br is in order to maintain the proper f unc ­
t ion of the climate control sys tem.

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.

186 Checking and filling
Engine cooling system
Coolant
The engine coolant performs two functions: it
keeps the engine from overheating and it pro ­
tects the engine from freezing in the winter .
The cooling system is sealed and generally re­
qu ires little attention .
The cooling system has been filled at the fac­
tory with a permanent coo lant which does not
need to be changed. The coolant consists of a
mixture of spec ially conditioned water and the
manufacturer's glycol-basedcoolant addi-
tive G13 antifreeze with ant icorros ion addi­
tives (50% for USA models; 60% for Ca nada
models) . This mixture both assures the neces­
sary frost protection and protects metal com­
ponents in the engine's cooling system from
corrosion and scaling.
It a lso raises the boil­
ing point of the coo lant.
Do not reduce the concentration o f the coo l­
ant in the summer by adding plain water .
The
proportion of coolant additive must be at
least 50% but not more than 60%
to main­
tain antifree ze protection and cooling efficien­
cy. If the coolant frost protect ion is too low,
the coolant could freeze and damage the veh i­
