Avoid damaging the vehicle
When you are driving on poor roads, or over curbs, steep ramps,
etc., make certain that low -lying parts such as spoilers and exhaust
system parts do not bottom out and get damaged.
This is especially true for vehicles with low -slung chassis (sports
chassis) and fu lly loaded vehicles.
Operate your vehicle economically
and minimize pollution
General
Your personal style of driving will determine the economy
o f your vehicle, as well as exhaust and noise levels.
Fuel economy, environmental impact, and wear on your engine,
brakes and tires largely depend on three factors:
• your personal driving style
• operating conditions
• technical limitat ions
If you anticipate what you need to do next and drive economically,
you can easily cu t your fue l consumption by 10 -15 percent . This
section will give you some tips on how you can help the environ­
ment and your pocketbook .
[ i ) Tips
The consumption estimates as published by ENVIRONMENTAL
PROTECT ION AGENCY (EPA) and Transport Canada may not corre­
spond to your actua l consumption on the road, which wi ll vary
depending upon vehic le load and speed, road and weather condi ­
tions, trip length, etc.
Drive smo~thly and keep a lookout ahead
Vehicles use the m ost fuel when they are accelerating.
Avoid unnecessary accelerating and braking.
Vehicles use the most fue l when they are accelerating . If you antici­
pate what is going to happen next, you will need to brake less and,
thus, accelerate less. Let the vehicle coast whenever possible -for
example when you see that the next traffic light is red.
Avoid full throttle
Driving at moderate speeds saves fuel and improves your
mileage.
-Try and keep we ll below your car's maximum speed.
Acce lerating gently reduces fuel consumption, engine wear, and
does not disturb the environment .
Fuel consumption, exhaust em issions and engine noise increase
disproportionately at high speeds. If you drive at approximately
three quarters of top speed, fuel consumption wil l be reduced by
one half. Never drive faster than the posted speed limit and weather
conditions permit .•
Reducing unnecessary idling
E ven when your car is just idling i t burns up fuel.
- Sh ut the eng ine off when you are not driving the vehicle.
- Do not warm up th e vehicle by letting the eng ine r un at
idle.
I t m akes sense to shut off the engine in traffic jams, when waiting
for trains to pass at rai lroad crossings, or at traffic lights that have

Trailer towing
Driving with a trailer
General information
Your Audi was designed primarily for passenger transpor­
tation.
If you plan to tow a trailer, please remember that the additional load
wi ll affect durability, economy and performance.
Trai ler towing not on ly p laces more stress on the vehicle, it a lso ca lls
for more concentration from the driver.
For this reasons, always fo llow the operating and driving instruc ­
tions provided and use common sense. •
Technical requirements
Traile r hit ch
Use a weight -carrying hitch conforming to the gross trailer weight.
The hitch must be suitab le for your vehicle and tra iler and must be
mounted secure ly on the vehicle's chassis at a
technically sound
location . Use only a trailer hitch w ith removable ball mount. A lways
check with the trai ler hitch manufacturer to make sure that you are
using the correct hitch .
Do not use a bumper hit ch .
The hitch must be installed in such a way that it does not interfere
w ith the impact-absorbing bumper system . No modifications
should be made to the vehicle exhaust and brake systems. From
time to time, check that all hitch mount ing 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
vehic le be struck from behind
=:> & .
Tire pre ssure
When towing a trailer, inflate the tires of your vehic le to the cold tire
pressure listed under "Full load"on the sticker on the right door­
jamb. Inflate trai ler tires to trai ler and tire manufacturers' specifica ­
tions.
Lights
The head ligh t settings should be checked wit h the trai ler attached
before driving off. Have the head lights adjusted as necessary so
t hat you can see the road ahead but not blind oncoming traffic.
Check to make sure both vehicle and trailer lights are working prop ­
erly.
Engin e cool ing sy stem
Towing a t rai ler makes the engine wo rk ha rder . It is important that
the cooling system's performance stands up to the additiona l
strain. Make sure that the coo ling syste m has enoug h fluid.
Traile r br akes
If your traile r is equipped wi th a braking system, check to be sure
that it conforms to al l regu lations.
T he trailer hydraulic brake system must not be directly connected to
the vehic le's hydrau lic brake sys tem.
Safety chai ns
Be sure trailer safety chains are properly connected from the trailer
to the h itch on the vehicle. Leave enough slack in the chains to
permit 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. _.

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 impor­
tant that you
always have clear vision to the rear .
& WARNING
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 .

against shifting, be it forward, backward or sideways.
Never allow a passenger to ride in a trailer:::::, & in "Driving instruc­
tions".
Tire pressure
When towing a trailer, inflate the tires of your vehicle to the cold tire
pressure listed under "Full load" on the sticker on the right door­
jamb. Inflate trailer tires to trailer and tire manufacturers' specifica­
tions.

T he best way to remove snow from windows and mirrors is to use a
brush . Use a non -abrasive
pla stic ice scraper -better still, a spray
deicer -to remove
ice from w indows and mirrors .
The windows must not be cleaned with insect remover or wax since
these can inter fere with the function of the w inds hie ld w iper blades
(chatter).
Oil, grease o r sil icone residue can be removed with
glass cleaner or
s ilicone remover . However, wax residue requires the use of a
spec ially fo rmulated so lvent . Please contac t your authorized Audi
dea ler for advice on safe products for wax removal.
Windows should also be c leaned on the inside at regular interva ls .
Never dry windows with the same chamois that you use to dry
painted surfaces . Wax residue on the chamois can impair vision
t hrough the windows .

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, particu larly considering the comparatively small patch
of rubber on each tire that assures that all -important contact
between you, your vehic le and the road.
Maintaining the correct tire pressure, making sure that your vehicle
and its tires do not have to carry more weight than they can safely
handle, avoiding damage from road hazards and regularly inspecting tires for damage inc luding cuts, s lashes irregular wear
and overa ll condition are the most important things that you can do
to help avoid sudden tire failure including tread separation and
blowouts.
A vo iding d am age
If you have to drive over a curb or similar obstac le, drive very slowly
and as close as possible at a right angle to the curb.
A lways keep chemica ls including grease, oi l, gaso line and brake
fluid off the tires.
Inspect the ti res regu larly for damage (cuts, cracks or b listers, etc.l .
Remove any foreign bodies embedded in the treads.
Storing tir es
Mark tires when you remove them to indicate the direction of rota ­
t ion. This ensures you to be able to mount them correctly when you
reinstal l them. When removed, the wheels or tires shou
ld be stored in a coo l, dry
and preferably dark place.
S tore tires in a vertical pos it ion if they a re not mounted on r ims, in
a horizonta l position if they are mounted on rims.
New tir es
New tires have to be broken in=>&.
The tread depth of new ti res may vary, according to the type and
make of tire and the tread pattern.
H idd en damage
Damage to tires and rims is often not readily visible. If you notice
unusual vibration or the vehicle pu lls to one s ide, this may indicate
that one of the tires has been damaged . The tires must be checked
immediately by an authorized Audi dealer or qualified workshop .
Unidire cti ona l t ires
A unidirectional tire can be identif ied by arrows on the sidewa ll, that
point in the direction the tire is designed to rotate . You must fo llow
t he specified directio n of rotation . This is necessary s o that these
tires can develop their optimum characteristics regarding grip, road noise, wear and hydrop laning resistance . For more information
