Lights
T he headl ight settings shou ld be chec ked with the tr ailer attached
before driving off. Check to make sure both vehicle and trailer lights
are wo rking properly.
Safety chains
Be sure tra ile r safety cha ins are p roperly connected from the t rai ler
to the hitch on the vehicle. Leave enough slack in the chains to perm it
tu rning corners . When you install sa fe ty ch ains, ma ke sure they will
not drag on the road when you are driving.
T he chains should cross under the trai ler tongue to prevent it from
dropping in case of separation from the h itch .

Driving instructior,s
Driving with a trailer always requires e xtra care and
consideration.
To obtain the best possib le handling of ve hicle a nd trailer ,
please note the following :
- Do not tow a loaded trailer when your car itself is not
loaded.
- Be especia lly careful when pass ing other vehicles .
- Observe speed limi ts.
- Do not drive at the maximum pe rmissible speed.
Controls and equip­
ment Safety first Vehicle operation
- Always apply brakes early.
- Mo
nitor the temperature gauge.
Weight distri but ion
T owing a loaded trailer with an empty car results in a highly unstable
distribution of we ight . If t his cannot be avoided , drive at very low
speeds only to avoid the risk of losing steering control.
A "balanced" rig is easier to operate and control. This means that the
tow veh icle shou ld be loaded to the extent poss ible and permissib le,
wh ile keeping the tra ile r as lig ht as poss ible unde r the ci rc u mstances.
Whe never possible, transfer some cargo to the luggage compart ­
me nt o f the tow vehicle while observing tongue load requirements
and vehicle loading considerations.
Speed
The higher the speed, the more d ifficult it becomes for the driver to
control the r ig . Do not dr ive at the maxim um permiss ible speed .
Reduce your speed eve n more if load, weather or w ind conditions are
unfavorable -particular ly when going downhill.
Reduce vehicle speed
immed iately if the tra ile r shows the slightest
sign of swaying.
Do not tr y to stop the s wayi ng by a ccele rating .
Observe speed lim its. In some areas, speeds for veh icles towing
trailers are lowe r than for regular veh icles .
Always apply brakes early. When driving downhi ll, shift into a lower
gear to use the engine brak ing effect to slow t he ve hicle . Use of the
brakes alone can cause them to overheat and fa il.
Coolant temperatur e
The coo lant temperature gauge=> page 10 must be observed care­
fu lly. If the needle moves close to the upper end of the sca le, reduce
speed immediately and/or turn off the air conditioner.
If the coo lant temperature warning light in the instrument clus ter
starts flash ing
- F- , pull off the road, stop and let the engine idle for
about two m inutes to prevent hea t buil d-up.

Trailer towing tips
Important to know
Your vehicle handles differe ntly when tow ing a tra iler because of the
additiona l weight and different we ight distribution. Safety, perfor­
man ce and economy w ill greatly depend on how ca refu lly yo u load
your trailer and operate your rig.
Be fore you actua lly tow your tra ile r, prac tice turning, stopp ing and
back ing u p in a n area away from traffic. Keep pract ic in g until you have
become completely familiar with the way your vehicle -trailer combi­
nation behaves and responds .
Backing up is diff icult and requ ires pract ice. Backing up w ith a trailer
gene rally requires s teer ing a ction opposi te to th at when ba cki ng up
your vehicle witho ut a trailer.
Maintain a greate r d istance between your ve hicl e and the one in front
of yo u. You will need more room to stop . T o compensate fo r the
trai ler, you will need a larger than normal turning radius .
W hen p assing, remember that you c annot acceler ate as fast as yo u
normally wou ld because of the added load. Make sure yo u have
enoug h room to pass. After passi ng, allow plen ty of room fo r yo ur
tra iler before changing lanes again .
Avoid jerky starts, sharp turns or rapid lane changes .
[ i ] Tips
• Do not tow a trai ler d uring the brea k-in perio d of your vehicle. •
If you tow a tra iler, your Aud i may require more frequent mai nte­
n an ce due to the ex tra load:::::>

Parking on a slope
Do not park on a slope with a trailer. If it cannot be
av oided, do so only after doing the following:
When parking:
- Apply the foot brak e.
- Have someone p lac e chocks un der bo th the vehicle and t he
traile r w he els .
- With c hoc ks i n place, slowly release the brakes u ntil the
wheel c hoc ks absorb t he load.
- Turn the w hee ls towards t he curb .
- A pply the parking brake.

[ i ] Tips
T he b rake fl uid reservoir is located unde rneath t he cover. •
Changing brake fluid
Have the b rake fluid chan ged by an exp eri enc ed t echni ­
cian.
B ra ke flui d absorbs mois ture fro m th e air . If the w ater con ten t in the
brake fl uid is too high, corros io n in th e brake system may result afte r
a p eriod of time. The boil ing po int of the br ake fl uid will also de cre as e
cons iderab ly and decr ease brak ing performa nce.
Th erefo re, the brake fl uid m ust be changed
every two years. Always
use new br ake fluid w hich conforms to Federal Motor Veh icle Stan­
dard "FMVSS 1 16 DOT
4" .
The b rake fl uid reservo ir can be diffi cult to rea ch, there fore, we
recommend that you have the brake fluid c hanged by your author ized
Audi dealer. Your dea ler has the correct tools, the rig ht b rake f luid
and the k now-how to do t his for you .
& WARNING
• Brake fluid is poisonous. It must be stored only in the closed
original container out of the rea ch of children!
• Brake failure can result from old or inappropriate brake fluid.
Observe these precautions:
-Use only brake fluid that meets SAE specification
J 1703 and
conforms to Federal Motor Vehicle Standard 116. Alway s check
with your authorized Audi dealer to make sure you are using
the correct brake fluid. The correct type of brake fluid is also indicated on the brake fluid reservoir .
& WARNING (co ntinued )
-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.

& WARNING (continued)
• Carrying more weight than your vehicle was designed to carry
will prevent the vehicle from handling properly and increase the risk of the loss of vehicle control.
• The brakes on a vehicle that has been overloaded may not be
able to stop the vehicle within a safe distance.
• Tires on a vehicle that has been overloaded can fail suddenly,
including a blowout and sudden deflation, causing loss of control
and a crash.
• Always make sure that the total load being transported -
including the weight of a trailer hitch and the tongue weight of a
loaded trailer -does not make the vehicle heavier than the
vehicle's Gross Vehicle Weight Rating. •
Determining correct Load Limit
Use the example below to calculate the
total weight of the passengers and luggage or other things that you plan to transport so
that you can make sure that your vehicle
will not be overloaded.
Safety first
Tires and wheels 11111
Steps for Determining Correct
Load Limit
1.Locate the statement "THE COMBINED
WEIGHT OF OCCUPANTS AND CARGO
SHOULD NEVER EXCEED XXX KG OR XXX LBS"on your vehicle's placard (tire infla­
tion pressure label)==>
page 322,
fig. 241.
2. Determine the combined weight of the driver and passengers that will be riding
in your vehicle.
3. Subtract the combined weight of the driver and passengers from
"XXX" kilo­
grams or
"XXX" pounds shown on the
sticker==>
page 322, fig. 241.
4. The resulting figure equals the available amount of cargo and luggage load
capacity. For example, if the
"XXX"
amount equals 1400 lbs. and there will be five 150 lbs. passengers in your
vehicle, the amount of available cargo
and luggage load capacity is 650 lbs.
(1400-750 (5
X 150) = 650 lbs.) •

& WARNING
• Using incorrect or unmatched tires and/ or wheels or improper
tire and wheel combinations can lead to loss of control , collis ion
and seriou s personal injury.
& WARNING (co ntinued )
• Always use tires, rims and wheel bolts that meet the specifica­
tions of original factory-installed tires or other combinations that have been specifically app roved by the vehicle manufacturer.
• Tires age even if they are not being used and can fail suddenly,
especially at high speeds . Tires that a re 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 history ." Old used tires may have been damaged
eventhoughthedamagecannotbeseenthatcanleadtosudden
tire failure and loss of vehicle control.
• All four wheels must be fitted with radial tires of the same
type , size (rolling circumference) and the same tread pattern.
Driving with different tires reduces vehicle handling and can lead
to a loss of control.
• If the spare tire is not the same as the tires that are mounted
on the vehicle - for example with winter tires - only use the spare
tire for a short period of time and drive with extra care . Refit the
no rmal road wheel as soon as safely possible .
• Never drive faster than the maximum speed for which the tires
on your vehicle are rated because tires that are driven faster than
their rated speed can fail suddenly .
• Ove rloading tire s cause heat build-up, sudden tire failure,
including a blowout and sudden deflation and loss of control.
• Temperature grades apply to tires that are properly inflated
and not over or underinflated.
• For technical rea sons it is not always possible to use wheels
from other vehicles- in some cases not even wheels from the same
vehicle model.
• If you install wheel trim discs on the veh icle wheels, make sure
that the air flow to the brakes is not blocked . Reduced airflow to
the brakes can them to overheat , increasing stopp ing distances
and causing a colli sion.
