210 Trailer towing
Make sure that the cooling system has eno ugh
fluid .
Tire p res sure
When tow ing a trai le r, inflate the t ires of your
vehi cle to the co ld tire pressure listed under
"Full load" on the label located on the driver's
side B-pillar (visible when the door is open) .
Inflate trailer t ires to trai ler and tire manufac­
turers' specifications.
Lights
Chec k to make s ure both veh icle and trailer
lights are working properly.
Safety chains
Be sure tra iler safety cha ins are properly con­
nected from the trailer to the hitch on the ve­
h icle. Leave enough slack in the chains to per ­
mit turn ing corners . When you install safety
cha ins, make su re they wi ll not drag on the
road when yo u are driving.
The chains shou ld cross under the tra iler
tongue to prevent it from dropping in case of
separation from the hitch.
Adjusting the Audi drive select
Make sure the vehicle is on a level su rface be­
for e
hitching up the tra ile r and b efor e adjust­
ing the tongue weight. The vehicle must be in

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 fo llow ing:
.,. Do not tow a loaded trailer when your car it­
self is not loaded.
.,. Be especially carefu l when passing other
veh icles.
.,. Observe speed lim its .
.,. Do not dr ive at the maximum permissible
speed.
.,. Always app ly brakes early .
.,. Monitor the temperatu re ga uge.
Weight distribut ion
T owing a loaded trailer with an empty car re­
su lts in a highly unstab le distribution of
we ight. If this cannot be avoided, drive at very
low speeds on ly to avoid t he risk of losing
steering con trol.
A "ba lanced " rig is easier to operate and con­
tro l. This means that the tow vehicle should
be loaded to the exten t possible and permissi­
ble, while keep ing the trai ler as light as possi­
ble under the c ircumstances . Whenever poss i­
ble, transfer some cargo to the luggage com ­
partment of the tow veh icle while observing
tong ue load requirements and vehicle load ing
considerations.
Speed
The higher the speed, the more difficu lt it be ­
comes for the driver to control the rig . Do not
drive at the maximum permissible speed. Re­
duce your speed even more if load, weather or
wind conditions are unfavorable -particularly
whe n going downhill.
Red uce veh icle speed
immediately if the trail­
er shows the slightest s ign of sway ing .
Do not
try to stop the swa ying b y accelerating .
Observe speed limits . In some a reas, speeds
for vehicles tow ing trai lers are lower than for
regular veh icles . .,.

Always apply brakes early. When driving
downhill, shift into a lower gear to use the en­
g ine braking effect to slow the vehicle . Use of
the brakes a lone can cause them to overheat
and fail.
Coolant temperature
The coolant temperature gauge ¢ page 11
must be observed carefully. The coo lant tem­
perature can increase if you drive on long in­
clines in a low gear at high engine speeds. Re­
duce your speed immediately if the LEDs in
the top part of the display turn on .
For more information about indicator lights,
refer to.

A WARNING
Anyone not properly restrained in a mov­
ing vehicle is at a much greater risk in an
accident . Never let anyone r ide in your car
who is not properly wearing the restra ints
provided by Aud i.
Trailer towing tips
Important to know
Your vehicle hand les different ly when towing
-
a trailer because of the additional weight and
d ifferent weight distribution . Safety, perform­
ance and economy w ill greatly depend on how
carefully you load your trailer and operate
your rig .
Before you actually tow your trailer, practice
turning, stopp ing and backing up in an area
away from traffic . Keep practicing until you
have become completely familiar with the way
your veh icle-trailer comb ination behaves and
responds .
Backing up is diff icult and requires practice .
Backing up with a tra iler genera lly requires
steer ing action opposite to that when backing
up your vehicle without a trailer.
Maintain a greater distance between your ve­
hicle and the one in front of you. You will need
more room to stop. To compensate for the
Trailer towing 211
trailer, you wi ll need a larger than normal
turning radius.
When passing, remember that you cannot ac­
ce lerate as fast as you norma lly would be­
cause of the added load. Make sure you have
enough room to pass. After passing, allow
plenty of room for your trailer before chang­
ing lanes again.
Avoid jerky starts, sharp turns or rapid lane
changes.
(0 Tips
- Do not tow a trailer during the break-in
period of your vehicle.
- If you tow a trailer, your Audi may re­
quire more frequent maintenance due to
the extra load¢
page 289.
Parking on a slope
Do not pork on a slope with a trailer . If it can­
not be avoided, do so only after doing the fol­
lowing:
When parking:
"' App ly the foot brake .
.,. Have someo ne p lace chocks under both the
veh icle and the trailer wheels.
"' With chocks in place, slowly release the
brakes until the wheel chocks absorb the
load .
.,. Turn the wheels towards the curb .
.,. Apply the parking brake.
.,. Select the P selector lever posit ion .
When restarting after parking:
.,. Apply the foot brake.
.,. Start the engine .
.,. Select the D/S se lector lever position .
.,. Release the parking brake and slowly pull
out and away from the wheel chocks.
.,. Stop and have someone retr ieve the wheel
chocks .

Cleaning and protect ion
General information
Regular core preserves vehicle value.
Any automobile is exposed to industrial
fumes , corrosive road salt, etc. A well cared
for Audi can look like new many years after
purchase . Regu lar and correct care w ill con­
tr ibute to maintaining the beauty and value of
your Aud i.
F u rth ermor e, good c are may be a conditi on

Your authorized Audi dealer has a variety of
dedic ated veh icle-car e products and can ad ­
vise which ones to use for cleaning the exter i­
or and interior of your vehicle.
Whether you use products recommended by
Aud i or other commercially available clean ing
agents, please make sure you apply them cor­
rectly .
A WARNING
-Cleaning agents may be poisonous. Keep
them out of the reach of children.
- Heed all caut ion labels.
- Always read directions on the container
before using any product. Follow the di­
rect ions carefu lly.
- Most chemical cleaners are concentrated
and have to be diluted .
- Use spot removing fluids only in well
ventilated areas.
- Do not use gasoline, kerosene, d iesel
fuel, nail polish remover or other volatile
fluids. They may be toxic, flammab le or
haza rdous in other ways. Do not wash,
wax or dry the vehicle with the ign it ion
on or the engine running.
- Do not clean the undersides of chassis,
fenders, wheel covers, e tc. w ithout pro­
tecting your hands and arms. You may c u t yourself on sharp -edged metal parts .
Cleaning and protec tion 213

Care of exterior
Washing
Frequent washing protects the vehicle .
The best protection against environmental i n­
fluences is
frequent washing and waxing . How
often t his is required depends on:
- How much the veh icle is used
- Where the veh icle is parked (garage, in the
open under trees, etc.)
- The seasonal and weather conditions
- Environmental infl uences
T he longer b ird droppings, insects, tree resin,
road and indus tria l gr ime, ta r, soot, road salt
and other materials remain on the vehicle
body, the more lasting their destructive ef­
fects wi ll be . High temperatures caused by ex­
posure to intense sun light intens ify the corro­
s ive effect, particularly when humid ity is high
as well.
Under certain circumstances,
weekl y washing
may be necessary. Under other cond itions, a
monthly washing and waxing may be ade­
quate .
After the winter, the underside of the vehicle
should be thoroughly washed, preferab ly in a
professional car wash .

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
powerplant that was built to exacting specifi­
cations . This engine needs the right kind of
engine oil that meets specifications regarding
quality and viscosity so that it can run
smoothly and reliably . Choosing the right oil
and changing oil within the time and mileage
intervals printed in you r vehicle's Warranty
&
Maintenance booklet matters a lot more to­
day than it did years ago . Audi has developed
a special quality standard for engine oil that
will help assure that your vehicle's engine wi ll
get the lubrication it needs for proper opera-
tion. ..,.

scalding from hot coo lant by following
these steps.
- Turn
off the engi ne and a llow it to cool
down.
- Protect your face, hands and arms from
escapi ng fl uid and steam by cover ing
the cap with a large, thick rag .
- Turn the cap slowly and very ca refully

a pply ing lig ht, downwa rd p ress ure on
the top of the cap.
- To avo id being burned, do no t sp ill an­
tifree ze o r coolan t on t he exh aust sys­
tem or ho t engine parts . Un der certain
conditions, the ethylene glyco l in en­
gine coolant can catch fire .
- Antifree ze is poisono us. Always store an­
tifreeze in its or iginal co ntainer and we ll
o ut o f the reac h of children.
- If you drain the coolant , it must be
caught and safely stored in a p roper con ­
tainer clear ly marked "poison".
(D Note
- Coolant po llutes the env ironment and
could ca use a n engine fire . Excess coo l­
ant wi ll be forced out through the pres ­
sure re lief va lve 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 237 must be re­
stored as soon as possib le .
@ For the sake of the environment
Drained coolant should not be re used . Al­
ways dispose of used c oolant while observ­
ing all envir onmental regulations .
Radiator fan
The radiator fan switches on automa tically by
itself
An auxiliary e lectric radiator fa n switches on
and
off depending on coolant temperature
and other ve hicle operating conditions.
Checkin g and fillin g 239
After you switch the engine off, the auxi liary
fan can continue running for up to 10 minutes
- even w ith the ign ition off. It can even switch
o n again later by itself¢.& , if
- the temperature of the engine coo lant rises
due to the heat build- up from the engine in
the engi ne compartment, or
- the engine compa rtment heats up because
the vehicle is parked in intense sunlight.

low the "MIN" mark, the brake warning/ind i­
cator light
1111 (U .S . models)/ . (Canadian
models) will come on¢
page 15. Do not con­
tinue to operate the vehicle. The comp lete
brake system shou ld be thoroughly checked
by an au thorized Audi dealer or other quali­
fied facility and the cause corrected . If the
brake fluid level is too low, the brake warn ing/
indicator light w ill illuminate . Contact an au­
thor ized Audi dealer
imm ediatel y.
Changing brake fluid
Have the brake fluid changed by an experi­
enced technician .
Brake fluid absorbs moisture from the a ir . If
the water content in the brake fluid is too
h igh , corros ion in the brake system may result
after a per iod of t ime . The bo iling po int of the
brake fluid w ill also decrease considerably and
dec rease braking performance.
Therefore, the brake flu id must be changed
ev ery two year s. Always use new b rake fluid
which conforms to Fede ral Motor Vehicle
Standard "FMVSS
116 DO T 4".
The brake flu id reservoir can be difficult to
r each, therefo re , we recommend that you
have the brake fl uid changed by yo ur author­
ized
Audi d ealer. Your dea ler has the correct
too ls, the right brake fluid and the know -how
to do this for you .
A WARNING
-Brake fluid is poisonous . It must be stor ­
ed only in the closed orig inal container
out of the reach of children!
- Brake fa ilure can result from old or inap­
propriate brake fluid. Observe these pre­
caut ions: -
Use only brake fluid that meets SAE
specification
J 1703 and conforms to
Federa l Motor Vehicle Standard
116.
Always check with your authorized Audi
dealer to make sure you are using the
correct brake fluid . The correct type of
brake f lu id is also ind icated on the
brake flu id reservoir.
- T he brake fluid must be new. Heavy use
of the bra kes ca n cause a vapo r lock if
the b rake fluid is left in the system too
l ong . This can seriously affect the effi ­
c iency of the brakes as well as your
safety. This co uld resu lt in an accident.
(D Note
Bra ke fluid will damage the paint of you r
vehicle .
(® For the sake of the environment
Because of the p rob lem of p roper disposal
of b ra ke fluid as well as the spec ial too ls
r equired and the necessary expertise, we
re commend that you have the brake fluid
changed by yo ur authorized Aud i dea ler.
