Economical and environ­
mentally-friendly driving
General
Your personal style of driving will determine the
economy of your vehicle, as well as exhaust and
noise levels.
F ue l economy, environmenta l impact, and we ar
on your engine, brakes and tires la rgely depend
on three factors :
- you r persona l dr iving sty le
- operating conditions
- technical lim itations
If you anticipate what you need to do next and
drive economically, you can eas ily cut your fue l
consumption by
10-15 percen t. This section will
g ive you some tips on how you can help the envi ­
ronment and yo ur pocketbook .
(!) Tips
The consumpt ion estimates as published by
ENVIRONMENTAL PROTECTION AGENCY (EPA) and Transport Canada may not cor re­
spond to your actual consumption on the
road, which will va ry depending upon vehicle
load and speed, road and wea ther condi tions,
t rip length, etc.
Drive smoothly and keep a lookout ahead
Vehicles use the most fuel when they are acceler­
ating.
" Avoid unnecessary accelerating a nd braking .
Veh icles use the most fuel when they are acceler ­
ating . If you anticipate what is going to happen
next , you will need to brake less and, thus, accel­
e rate less . let the vehicle coast wheneve r possi ­
b le -fo r example when yo u see that the next traf­
fic light is red.
Driving and the envir onment
Avoid full throttle
Driving at moderate speeds saves fuel and im­
proves your mileage .
"Try and keep well below your car 's maximum
speed.
Acce lerating gently reduces fuel consumption,
engine wear, and does not disturb the environ­
ment.
Fuel consumption, exhaust emissions and engine
noise increase disproport ionately at high speeds.
If you drive at approximately three quarters of
top speed, fuel consumption will be reduced by
one half. Never drive faster than the posted
speed limit and weather cond itions permit .
Reducing unnecessary idling
Even when your car is jus t idling it burns up fuel.
" Shut the eng ine off when you are not driving
the vehicle.
" Do not warm up the vehicle by lett ing the en-
gine run at idle.
It makes sense to shut off the engine in traffic
jams, when waiting for trains to pass at railroad cross ings, or at traff ic lights that have long waits
on red . Turning the engine off for just
30 -40 sec ­
onds saves more f uel than is burned starting the
. . engine again.
It takes a long time for the eng ine to warm up
fully when it is running at idle . However, wear
and noxious emissions are especially h igh when
the engine is warming up . So yo u should dr ive
away as soon as you start the eng ine and avoid
runn ing at high rpms w hile the engine is st ill
warming up .
(D Note
Do not leave eng ine idling unattended after
s tart ing. If wa rning lights sho uld come on to
i ndicate improper operation, they would go
unheeded . Extended idling also prod uces
heat, which could resu lt in overheating or
other damage to the vehicle or other proper­
ty .

Trailer towing Driving with a trailer
General information
Your Audi was designed primarily for passenger
transportation .
If you plan to tow a trailer, please remember that
the additional load will affect durability, econo­
my and performance.
Trailer towing not only places more stress on the
vehicle, it also calls for more concentration 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 suitable
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 re­
movable ball mount . Always check with the trail­
er hitch manufacturer to make sure that you are
using the correct hitch.
Do not use a bumper hitch.
The hitch must be installed in such a way that it
does not interfere with 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 mounting
bo lts remain securely fastened.
When you are not towing a trailer,
remove the
tra iler hitch ball mount . This prevents the hitch
from causing damage shou ld your vehicle be
struck from beh ind ¢
,&. .
Trailer brakes
If your trailer is equipped with a braking system,
gi check to be sure that it conforms to all regula-......
~ tions . N ...... 0

LL 00
Trailer towing
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
T ra iler lights must meet all regulations . Be sure
to check w ith your author ized Audi dealer for cor­
rect wiring, switches, and relays.
Mirrors
If you are unable to see the traffic behind you us­
ing the regular outside mirrors, then you
must in­
stall extended mirrors. It is important that you
always have clear vision to the rear.
,8. WARNING
-If a tra iler has electr ical brakes please note
that these bra kes 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 in­
jure you or your passengers.
Operating instructions
Maximum trailer weight
A trailer for your vehicle is limited to a typical
class 1 or class 2 trailer.
Trailer load distribution
Be sure the load in the trailer is held sec ure ly in
place to prevent it from shifting forward, back­
ward or sideways.
Never allow a passenger to ride in a trailer¢.&.
in Driving instructions on page 180.
Engine cooling system
Towing a trailer makes the engine work harder . It
is important that the cooling system's perform ­
ance is up to the additional load . Make sure that
the cool ing system has enough fluid. .,..

Trailer towing
Tire pr essure
When tow ing a tra iler, inflate the tires of yo ur
veh icle to the tire pressure listed under " Fu ll
load" on the label ¢
page 217. Inflate trai ler
tires to trai ler and tire manufacturers' specifica­
tions.
Lights
The headlight settings should be chec ked with
the trailer attached before driving off . Check to
make sure both vehicle and trailer lights are
working properly.
Safety chains
Be s ure t railer safety chains are properly connect­
ed from the trailer to the hitch on the vehicle .
L eave enough slack in the chains to permit turn ­
ing corners. When you install safety chains, make
sure they wi ll not drag on the road when you are
driving.
The chains shou ld 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 .
Weight distribution
Towing a loaded trailer with an empty car res ults
in a high ly unstable distribution of weight . If this
cannot be avo ided, drive at very low speeds on ly
to avoid the risk of losing steering control.
A "balanced" rig is easie r to operate and cont rol.
This means that the tow vehicle should be loaded
to the extent possible and permissible, while keeping the trai ler as light as possib le under the
circumstances . Whenever possible, transfer
some cargo to the luggage compartment of the
tow vehicle while observ ing tongue load requ ire­
ments and vehicle loading considerat ions .
Spe ed
The higher the speed, the more difficult it be­
comes for the driver to contro l the rig. Do not
drive at the maximum permiss ible speed. Reduce
your speed even more if load, weather or w ind
180
conditions are unfavorab le -particularly when
going downhi ll.
Reduce vehicle speed
immediate ly if the trailer
shows the slightest sign of sway ing.
Do not try
to st op the swaying by accele rating.
Observe speed limits. In some a reas, speeds fo r
vehicles towing tra ilers are lower tha n for regular
vehicles.
A lways apply brakes ear ly . When driving down­
hill, shift into a lower gea r to use the engine
braki ng effect to slow the vehicle. Use of the
brakes alone ca n cause them to overheat and fa il.
Coolant temperature
The coolant temperature gauge¢ page 8 must
be observed carefully. If the needle moves close
to the upper end of the scale, reduce speed im­
med iate ly and/or tu rn off the a ir cond itioner .
If the coolant temperatu re warning light . in
the instrument cluster starts flashing, p ull off
the road, stop and let the engine
idle for about
two minu tes to p revent heat build-up .
.&, WARNING
Anyone not properly res trained in a moving
vehicle is at a much greater risk in an acci ­
dent . Never let anyone ride in your car who is
not properly wear ing the restraints provided
by Aud i.
Trailer towing
information
Important to know
-
Your vehicle handles differently when towing a
trailer because of the addit iona l weight and dif­
ferent weight distribution. Safety, performance
and economy will greatly depend on how careful­
ly you load your tra iler and operate your rig.
Before you actually tow your trailer, pract ice
turning, stopping and backing up in an area away
from traffic. Keep pract icing u nti l you have be­
come completely fam iliar w ith the way your vehi-
cle-tra ile r combination behaves and respo nds . .,.

- To reduce the risk of cuts, protect yourself
from sharp metal components when wash­
ing the underbody or the inside of the wheel
housings .
- After washing the vehicle, the brak ing effect
may be delayed due to mo isture on the
brake rotors or ice in the w inter . This in­
c reases the risk of an acc ident. The bra kes
must be d ried fi rst w ith a few careful b rake
applications.
(D Note
- If you wash t he vehicle in an automatic car
wash, yo u m ust fold the exte rior m irrors in

Ca re and cleaning
- To re duce the risk of damage to the surface,
do not use insect removing sponges, kitchen
sponges or s imilar items .
- Matte finish painted veh icle components:
- To reduce the risk of damage to the sur-
face, do not use po lishing agents or hard
wax.
- Never use protective wax . It can destroy
the matte finish effect .
- Do not place any stickers or magnetic
signs on vehicle parts painted with matte
finish paint . The paint cou ld be damaged
when the stickers or magnets are re­

and "MAX " markings.
The brake fluid reservoir is located at the rear
partition of the engine compartment on the left
side
¢ page 195.
The fluid level may drop slightly after some time
due to the automatic adjustment of the brake
pads . This is not cause for alarm .
If the brake fluid level falls
considerably below
the ' 'MIN" mark, the brake warning/indicator
light (U .S. models:
1111 , Canadian models: 1111)
will come on¢ page 13 . Do not continue to oper­
ate the vehicle . The complete brake system
should be thoroughly checked by an authorized
Aud i dealer or qualified workshop and the cause
corrected . If the brake fluid level is too low, the
brake warning/indicator light w ill illuminate.
Contact an author ized Audi dealer
immediately.
(D} Tips
The brake fluid reservoir is located under­
neath the cover.
202
Changing brake fluid
Have the brake fluid changed by an experienced
technician .
Brake fluid absorbs moisture from the air. If the
water content in the brake fluid is too high, cor­
rosion in the brake system may result after ape­
riod of time . The boiling po int of the brake fluid
will a lso decrease considerably and decrease
braking performance.
Therefore , the brake fluid must be changed
every
two years .
Always use new brake fluid which con­
forms to Feder-al Motor Vehicle Standard "FMVSS
116 DOT 4 ".
The brake fluid reservoir can be difficult to reach ,
therefore, we recommend that you have the
brake fluid changed by your author ized
Audi
dealer .
Your dealer has the correct tools, the
right brake fluid and the know-how to do this for
you.
A WARNING
- Brake fluid is poisonous. It must be stored
only in the closed original container out of
the reach of children!
- Brake fai lure can result from o ld or inappro­
priate brake fluid. Observe these precau­
tions:
- Use only brake fluid that meets SAE speci­
fi cation
J 1703 and conforms to Federal
Motor Veh icle Standard 116. Always check
with your authorized Audi dealer to make
sure you are using the correct brake f luid .
The correct type of brake f luid is also indi­
cated on the brake fluid reservoir.
- The brake fluid must be new . Heavy use of
the brakes can cause a vapor lock if the
brake fluid is left in the system too long .
This can seriously affect the efficiency of
the brakes as well as your safety. This
could result in an accident.

Battery
General information
Under normal operating conditions, the battery
in your Audi does not need any maintenance.
With
high outside temperatures or long daily
drives we recommend that you have the electro­
lyte level checked by an authorized Audi dealer or
qualified workshop. The electrolyte level should
also be checked each time the battery is charged
¢ page 205.
Have the battery checked when you take your ve­
hicle in for serv ice. You are well advised to re­
place a battery t hat is older than 5 years.
Disconnecting the battery terminals
Some vehicle functions (power window regula­
tors, for example) are lost if the battery termi­ nals are disconnected. These functions have to be
relearned after the battery terminals are con­
nected again. To prevent th is, the battery should
only be disco nnected from the vehicle e lectr ica l
system when abso lutely necessary for repairs.
Vehicles not driven for long periods
If you do not drive your vehicle over a period of
several days or weeks, electrical components are
gradually cut back or sw itched off. This reduces
energy consumption and maintains starting ca ­
pability over a longer period¢
page 173.
Some of the conven ience functions may not oper­
ate, such as the interior lights or the power seat
adjustment. The convenience functions will be
available again when you turn on the ignition and
start the engine.
Winter operation
During the winter months, battery capacity tends
to decrease as temperatures drop . T his is be-
Checking and Filling
cause more power is also consumed while start­
ing, and the headlights, rear window defogger,
etc., are used more often.
Avo id unnecessary power consumption, particu­
larly in city traff ic or when traveling only short
distances . Let your authorized Audi dealer check
the capacity of the vehicle battery before winter
sets in ¢
page 205. A well charged battery will
not only prevent starting problems when the
weather is cold, but will also last longer .
(D Tips
If your vehicle is left standing for several
weeks at extremely low temperatures, the ve­
hicle battery should be removed and stored
where it w ill not freeze. This will prevent it
from be ing damaged and having to be re­
placed.
Working on the battery
Be especially careful when working on or near
the battery.
The battery is located in the luggage compart­
ment under the floo r. Before you check anything
in the luggage compartment,
read and heed all
