With a factory-installed trai ler hitch, the maximum permissible
trai ler weight is 6,615 lbs (3,000 kg). The maximum permissible
unbraked trailer weight is 1,650 lbs (750 kgl. With an
aftermarket
tr ailer h itch , the maxi mum pe rm iss ib le tra iler weigh t is 5,51 2 lb s (2,500
kg). These specifications apply when driv ing on roads having
an in cli ne of less t han 12% .

company or weig hing s tati on.
Wtih a
factory -installed trailer hi tch, the max imum perm issib le load
on the ball hitch may not exceed 66 2 lbs (300 kg) . With an
after
market
t ra iler hitc h, the max imum pe rmi ssible loa d on the ball h itch
may not exceed 55 1 lbs (250 kg). It is recommended to use the
m aximum p ermi ssi ble l oad.
Trailer load distribution B e sure the load in the trai ler is he ld securel y in place to prevent it
from shifting forward, backward or sideways.
Never allow a passenger to ride in a trailer=> & in "D riving ins truc
tions" on page 307.
Ball mount
T he trai ler hitch may only be used with suitab le ball mount and ball
=> fig. 276 . In sta llati on of t he hitch ball must be ca rr ie d o ut i n a ccor
dance with the manufacturer's instructions. At the height dimen
s io n of 1 .5 in (38 .5 mm) a tole ran ce o f+/- 0 .5 in (12 .7 mm) is pe rmis
sib le.
Engine cooling system
T owing a trai ler makes the engine work harder. It is important that
th e c ooli ng system 's per forman ce is u p to the a ddi tiona l loa d. Ma ke
sure that the coo ling s ystem has enough f luid.
Tire pressure
When towing a trailer, inflate the tires of your vehic le to the cold tire
p re ssure l is ted unde r "Full load" on th e tire press ure l abe l. On USA
vehic les, the tire pressure label is located on the driver's side 8 -
Page 309 of 426

pillar. On Canada vehicles, the tire pressure label is located either on
t he driver's side 8 -pillar or inside the fuel fil ler flap. Inflate trailer
tires to trailer and tire manufacturers' specifications.
L ight s
The head light settings should be checked with the trailer attached
before driving off . Check to make sure both vehicle and trai ler lights
are working properly.
Sa fety c hain s
Be sure trailer safety chains are properly connected from the trailer
to the hitch on the vehicle . Leave enough slack in the chains to
permit turning corners. When you insta ll safety chains, make sure
they will not drag on the road when you are driving .
The chains should cross under the tra iler tongue to prevent it from
dropping in case of separation from the hitch.
0 Note
If you are going to tow a traile r, you must activate the trailer opera
tion mode =>
page 211, "Towing a trailer" .
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 i tse lf is not
loaded .
- Be especia lly careful when passing other vehicles .
- Observe speed l imits.
- Do not drive at the maximum permiss ible speed .
Controls and equip
ment Safety first Vehicle operation
Tr
aile r t owing
Always apply brakes early .
- Monitor the temperature gauge .
Weigh t dis tr ibution
Towing a loaded trailer wi th an empty car results in a highly
unstable dis tribution of weight . If this 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 vehicle should be loaded to the extent possible and permis
sib le, while keeping the trailer as light as possib le under the circum
stances . Whenever possible, transfer some cargo to the luggage
compartment of the tow vehicle whi le observing tongue load
requirements and vehicle loading considerations .
Speed
The higher th e speed, the more difficu lt it becomes for the driver to
control the rig . Do not drive at t he maximum pe rmissible speed.
Reduce your speed even more
if load, weather or wind conditions
a re unfavorable -particularly when going downhil l.
Reduce vehicle speed
i mmedi ate ly if the trailer shows the slightest
sign of swaying.
Do not tr y to s top the swaying by accelerating .
Observe speed limits . In some areas, speeds for vehicles towing
trailers are lower than for regular vehicles .
Always apply brakes early. When driving downhill, shift into a lower gear to use the engine braking effect to slow the vehicle. Use of the
brakes alone can cause them to overheat and fa il.
Coo lant t emperatu re
The coolant temperature gauge=> page 13 must be obse rved care
ful ly. If the need le moves close to the upper end of the sca le , reduce
speed immediately and/or turn off the air conditioner .
If the coolant temperature warning light in the instrument cluster
starts f lashing
- f- , pul l off the road, stop and let the engine idle for
about two minutes t o prevent heat build -up.

Trailer towing tips
Important to know
Your vehicle handles differently when towing a trailer because of
the additional weight and different weight distribution. Safety,
performance and economy will greatly depend on how carefully you
load your trailer and operate your rig.
Before you actually tow your trailer, practice turning, stopping and
backing up in an area away from traffic. Keep practicing until you
have become completely familiar with the way your vehicle -trailer
combination behaves and responds.
Backing up is difficult and requires practice. Backing up with a
trailer generally requires steering action opposite to that when
backing up your vehicle without a trailer.
Maintain a greater distance between your vehicle and the one in
front of you. You will need more room to stop. To compensate for
the trailer, you will need a larger than normal turning radius.
When passing, remember that you cannot accelerate as fast as you normally would because of the added load. Make sure you have
enough room to pass. After passing, allow plenty of room for your
trailer before changing lanes again.
Avoid jerky starts, sharp turns or rapid lane changes.
[ i] Tips
• Do not tow a trailer during the break-in period of your vehicle. • If you tow
a trailer, your Audi may require more frequent mainte
nance due to the extra load~
page 401. •
Parking on a s1ope
Do not park on a slope with a trailer. If it cannot be
avoided , do so only after doing the following:
When parking:
-Apply the foot brake.
- Have someone place chocks under both the vehicle 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.
- Move the selector lever to
P.
When restarting after parking:
- Apply the foot brake.
- Start the engine.
- Move the selector lever to
D.
-Release the parking brake and slowly pull out and away
from the wheel chocks.
- Stop and have someone retrieve the wheel chocks.
[ i] Tips
I f you move the selector lever of the automatic transmission to P
before applying the parking brake and before blocking the wheels, II-

you may have to use more force later to move the lever out of the P
position .•

Windows
Clear vision to all sides.
Clean all windows regularly to remove road film and
carwash wax buildup.
- Remove snow from windows using a brush.
- Use a plastic ice scraper to remove ice from windows and
mirrors.
- Remove other residue on the windows with a spray-on
glass cleaner.
- Wipe the windows dry with a clean piece of cloth or
kitchen paper towel.
The best way to remove snow from windows and mirrors is to use a
brush. Use a non-abrasive plastic ice scraper -better still, a spray
deicer -to remove
ice from windows and mirrors .
The windows must not be cleaned with insect remover or wax since
these can interfere with the function of the windshield wiper blades (chatter).
Oil, grease , or silicone residue can be removed with glass cleaner or
silicone remover. However, wax residue requires the use of a
specially formulated solvent. Please contact your authorized Audi
dealer for advice on safe products for wax removal.
Windows should also be cleaned on the inside at regular intervals.
Never dry windows with the same chamois that you use to dry
painted surfaces. Wax residue on the chamois can impair vision
through the windows .
& WARNING
• Always read and heed all WARNINGS and other information
=> page 312.
& WARNING (continued)
• The windshield must not be treated with water-repellent mate
rials. They can increase glare under poor visibility conditions such
as wetness, darkness, or when the sun is low on the horizon. In
addition, they can cause the windshield wipers to chatter.
0 Note
• Never use warm or hot water to remove snow and ice from
windows and mirrors. This could cause the glass to crack.
• To prevent damage to the wires of the rear defogger, do not place
any adhesive stickers on the inside of the rear window over the
wires.
• To help prevent dirt from scratching the window, always scrape
in a forward direction -pushing the scraper away from you -never
back and forth .•
Weatherstrips
Complete car core includes the weatherstrips as well.
Apply a suitable rubber conditioner to the weatherstrips
from time to time.
To be able seal properly, the weatherstrips around the hood, doors,
rear lid, etc. must remain pliable. Spray the weatherstrips with sili
cone or coat them with talcum powder or glycerine to retain the
flexibility of the rubber and to protect them against freezing in the
winter.
& WARNING
Always read and heed all WARNINGS and other information

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

5. Determine the combined weight of luggage and cargo being loaded on the
vehicle. That weight may not safely exceed the available cargo and luggage
load capacity calculated in Step 4.
6. If your vehicle will be towing a trailer, load from your trailer will be transferred
to your vehicle. Consult this manual to determine how this reduces the avail
