vehicle. Follow the local legal regulations for in-

Engine cooling system
Driving with a trailer means a higher load on the
engine and the cooling system. Make sure the
cooling system contains enough coolant.
Engine coolant temperature
Pay attention specifically to the coolant tempera-
ture display when there are high outside temper-
atures, and when driving on long inclines
© page 16. Shift to a higher gear in a timely man-
ner.
Tires
Set the tire pressure on your vehicle for a “full
load”; see the tire pressure sticker page 246. If
necessary, also adjust the tire pressure on the
trailer according to the manufacturer's specifica-
tions.
The trailer and the vehicle should be equipped
with winter tires when driving in winter tempera-
tures.
Overrun brakes
If your trailer is equipped with an overrun brake,
it must be correctly adjusted and function cor-
rectly. When using a trailer with overrun brakes,
first brake gently then quickly. This reduces the
risk of jerking while braking if the trailer wheels
lock up.
Constant braking causes the brakes to over-
heat and can substantially reduce braking per-
formance, increase braking distance, or cause
complete failure of the brake system.
Attachments retrofitted on the vehicle may
cause damage, especially on the trailer hitch
ball head. In cases of damage, have the func-
tion checked by an authorized Audi dealer or
authorized Audi Service Facility.
— Block the wheels with chocks when parking
on inclines if the trailer is loaded.
~ Audi recommends having the vehicle in-
spected between the inspection intervals if
you tow a trailer frequently.
— Avoid driving with a trailer during the vehi-
cle break-in period.
Trailer hitch
Introduction
Only use a trailer hitch with a removable ball
hitch mount and ball hitch. The trailer hitch must
be permitted for the vehicle, the trailer and the
permitted total weight of the trailer being
pulled. Above all, it must be securely and safely
attached to the vehicle trailer.
Never mount a trailer hitch on the bumper. The
trailer hitch must be mounted in a way that does
not impair the function of the bumper. Do not
make any changes to the exhaust system and the
brake system.
Check regularly if the trailer hitch is securely
mounted. Always follow the instructions given by
the trailer hitch manufacturer.

Trailer brakes
If the trailer has its own brake system, then fol-
low the manufacturer specifications. However,
the brake system on the trailer must never be
connected to the vehicle brake system.
Safety chains
Make sure the safety chains are correctly applied
when pulling a trailer. The chains should hang
enough so that the trailer can drive around
curves. However, they must not touch the
ground.
If the trailer is equipped with electronic
brakes, these brakes cannot be activated by a
