Permissible tongue load
For best ve hicle handl ing un der t hese ch ange d co ndition s, adju st the
tra ile r l oad so that the tongue load is at the maxim um a llowab le or
sligh tly lower. You can get an app roxim atio n of the tongue load w it h
a bat hroom scale or you ca n measure the load at a t ruc king company
or we ighing st ation.
W it h a

on t he ba ll hitc h may not exceed 662 lbs (300 kg). W it h an
after­
market
tra ile r hi tc h, t he ma ximum pe rm issi ble loa d on the b all hi tch
may not exceed 551 lbs (250 kg). It is recommended to use the
maxim um permi ssible loa d.
Trailer load distribution
Be su re the load in t he tra ile r i s held se curely in p lace to p revent it
from shi fting forward, backwa rd or sideways.
Never allow a passenger to ride in a trailer=> & in "Dr ivin g in struc­

page 2 71.
Ball mount
The tra ile r hitch may on ly be used w ith suitable ball mount and ball
=> fi g. 221. I nstallat ion of the hi tch b all mus t be c arrie d out in acco r­
dance with the manufacturer's instructions . At the height d imension
of 1. 5 in (38 .5 mm) a toler ance of+/- 0.5 in ( 12. 7 mm ) is per miss ible
Engine cooling system
Towing a trailer makes t he eng ine work harder. It is impo rtant that
t he cooling system 's performan ce is up to the addi tional loa d. Mak e
sure that the coo ling system has enough fluid .
Tire pressure
When towing a trailer, inf late the tires ofyourvehicle to the cold tire
pre ssure listed unde r "Full lo ad" on t he tire pre ssu re lab el. Th e tire ...

pressure label is located o n the dr iver's side B-pillar. Inflate trailer
t ires to tra ile r and t ire ma nufacturers' spec ifications.

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:::::>
page 366. •
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.
- M ove th e selector le v er to
P.
When restarting after parking:
- A pply the foot brake .
- Start the engine .
- Mov e th e s elector lever to
D .
- Release the par king brake a nd s low ly pull o ut and away
fro m the w heel chocks.
- Stop a nd have someone retr ieve the w heel chocks .
(I) Tips
If you move the se lector lever of the a utomat ic t ransmiss ion to P

Cleaning and protection
General information
Regular care preserves vehicl e val ue.
Any automobile is exposed to industria l fumes, co rrosive road salt,
m ud dy dog fee t, e tc. A well c ared for Audi can look like new many
years after p urchase . Regular and correct care will contribute to
m aint aining the bea uty and val ue of your Audi.
Furthermore, good care may be a condition for substantiating a
warranty claim should corrosion damage or paint defects occur.
Y ou r au thor ized Audi d eale r h as a var iety of dedicated vehicle-care

co rrectly .
& WARNING
• Cleaning agents may be poisonous . Keep them out of the reach
of children.
• Heed all caution labels .
• Always read directions on the container before using any
product. Follow the directions carefully.
• Most chemical cleaners are concentrated and have to be
diluted .
• Use spot removing fluids only in well ventilated areas.
• Do not use gasoline, kero sene , diesel fuel , nail polish remover

shaped spray".
- Do
not hold the spr ay nozz le too close t o soft ma ter ials .
When cle ani ng the vehicle wi th a p owe r w ashe r always follow the
operat ing instruct ions . T his applies part icu larly to the
operating
pressure
and the spraying distance. M ain tain a suffic ien t distan ce to
so ft mater ia ls such as rubber hoses and sound/vibration deaden ing
materials (particularly on the unde rside o f the engine hood). Do no t
use a jet wh ic h sprays water in a
