Trailer towingL _____________________________________________ _
ment of the tow vehicle while observing tongue load requirements
and vehicle loading considerations.
Speed
The higher the speed, the more difficult it becomes for the driver to
control the rig. Do not drive at the maximum permissible speed. Reduce your speed even more under unfavorable load, weather or
wind conditions -particularly when going downhill.
Reduce vehicle speed
immediately if the trailer shows the slightest
sign of swaying .
Do not try to stop 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 lower
gear to use the engine braking effect to slow down the vehicle. Use of
the brakes alone can cause them to overheat and fail.
Coolant temperature
The coolant temperature gauge~ page 9 must be observed care­
fully. If the needle moves close to the upper end of the scale, reduce
speed immediately and/or switch off the air conditioner .
If the coolant temperature warning light in the instrument cluster
starts flashing
-t-, pull off the road , stop and let the engine idle for
about two minutes to prevent heat build-up.
& WARNING
Anyone not properly restrained in a moving vehicle is at a much
greater risk in an accident. Never let anyone ride in your car who is
not properly wearing the restraints provided by Audi. •
Trailer towing tips
Important to know
-------------
Your vehicle handles differently when towing a trailer because of the
additional weight and 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
completely become familiar with the way your vehicle-trailer combi­
nation behaves and responds.
Backing up is difficult and requires practice. Backing up with a trailer
generally requires steering action opposite of 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 299. •

Parking on a slope
Do not park with a trailer on a slope. 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 wheel
blocks absorb the load.
- Turn the wheels towards the curb.
- Apply the parking brake.
- Place an automatic transmission in
P, respectively a
manual transmission in first or reverse gear.
When restarting after parking:
- Start the engine .
- Shift transmission into gear .
- Release the parking brake and slowly pull out and away from the wheel blocks .
- Stop and have someone retrieve the wheel blocks.
[I] Tips
If you move the selector lever of the automatic transmiss ion to P
before applying the parking brake and before blocking the wheels,
you may have to use more force later to move the leve r out of the
P
position. •

(I] Tips
Keep silicone sprays off the windshield to avoid wiper smear in rain.•
Applies to vehicles: with steel whee ls (e.g. if refitted with winte r tir es)
Steel wheels
The wheels also have to be cleaned.
-Always include the hub caps and wheel rims when washing
your vehicle to remove road dirt, salt sprays and brake
dust.
If necessary, use a commercial wheel cleaner to remove accumulated
brake dust.
The wheel rims are easier to keep clean if they are regularly coated
with liquid wax.
Paint scratches should be touched up as soon as possible to prevent
corrosion~ page 210, "Touch-up paint".
& WARNING
• Moisture and ice on brakes may affect braking efficiency -
~ page 191, "General information". Test the brakes carefully
after each vehicle wash.
• Always read and heed all WARNINGS and the information
~page206. •
Applies to veh icles: w ith Cas t alloy whee ls
Cast (light) alloy wheels
Cast (light) alloy wheels require special care.
-Wash the wheels with a sponge or hose brush every other
week. -
For deep cleaning afterwards, use only a dedicated
acid­
free cast alloy wheel cleaner.
- Rub a coat of
liquid wax onto the rims every three month.
Be sure to reach and treat all parts of the rim.
To preserve the decorative appearance of the cast alloy wheels, some
special care is necessary. In addition to road dirt and salt, brake dust
is also corrosive.
If left on for too long, brake dust can cause pitting.
Use only special
acid-free cleaners formulated for alloy rims. Safe
products are available at your authorized Audi dealer. Never leave the
cleaner on the rims longer than specified on the label. If not rinsed
off promptly, the acid contained in some cleaners can attack the
threads on the wheel bolts.
Never use abrasive or metal polishing cleaning agents.
If the protec­
tive coating has been chipped, e.g. by kicked up road dirt, touch it up
as soon as possible.
& WARNING
• Moisture and ice on brakes may affect braking efficiency
~ page 191, "General information". Test the brakes carefully
each time you wash the vehicle.
• Always read and heed all WARNINGS and other information
~page 206. •
Body cavity sealing
The body cavity sealing does not need to be checked.
All body cavities which could be affected by corrosion have been thor­
oughly protected at the factory.
This sealing does not require any inspection or additional treatment.
If any wax should seep out of the cavity when the ambient tempera­
ture is high, it can be removed with a plastic scraper and a suitable
solvent. ..,
