Tire pressure
When towing a trailer, inflate the tires of your
vehicle to the tire pressure listed under "Full
load" on the label ¢ page 221. Inflate trailer
tires to trailer and tire manufacturers'
specifica-
tions .
Lights
Check to make sure both vehicle and trailer lights
are working properly.
Safety chains
Be sure trailer safety chains are properly connect-
ed from the trailer to the hitch on the vehicle.
Leave enough slack in the chains to permit turn-
ing corners. When you install safety chains, make
sure they will not drag on the road when you are
driving.
The chains should cross under the trailer tongue
to prevent it from dropping in case of separation
from the hitch.
Adjusting the Audi drive select
Make sure the vehicle is on a level surface before
hitching up the trailer and before adjusting the
tongue weight. The vehicle must be in auto or

Driving instructions
Driving with a trailer always requires extra care
and consideration .
Weight distribution
Towing a loaded trailer with an empty car results
in a highly unstable distribution 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 permissible, while
keeping the trailer as light as possible under the
circumstances . Whenever possible, transfer
some cargo to the luggage compartment
of the
tow vehicle while observing tongue load require-
ments and vehicle loading considerations.
Speed
The higher the speed, the more difficult it be-
comes for the driver to control the rig . Do not
drive at the maximum permissible speed. Reduce
your speed even more if load, weather or wind
conditions are unfavorable - 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 down -
hill, 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 fail.
Air suspension*
When driving with a trailer, activate the trailer
mode of the air suspension. Switch the air sus -
pension trailer mode on when you are towing a
trailer. This will limit the regulation by the air
suspension while driving . Select in the MMI:
