Tongue weight
The maximum pe rmitt ed tongue weight of the
trailer drawbar on the trailer hitch ball head may
not be exceeded .
If the tongue we ight is too low , this affects the
trailer's handling . For dr iving safety, we recom-
mend to always utilize the maximum permitted
tongue weight, but not exceed it. You can reach
it, for example , by distributing the cargo in the
trailer correctly.
You can determine the tongue weight, for exam-
ple, with a bathroom scale or a public weigh sta -
tion .
The permitted tongue we ight of your veh icle can
be found in the vehicle documentation or in
¢ page 376.
Load distribution
Poor cargo load and distribution can negatively
impact vehicle handl ing .
- Store objects preferably in the vehicle luggage
compartment . The vehicle shou ld always carry
the heaviest possible load and the trailer
shou ld have the lightest possible load.
- Distribute the load in the tra iler so that the
heavy objects are as close to the ax le as possi-
ble.
- Secure objects from slid ing out of place.
- Utilize the maximum permitted tongue we ight
if possible .
Tires
Set the tire pressure on your vehicle for a "full
load"; see the t ire pressure sticker¢
page 340 .
If necessary, also adjust the tire pressure on the
trailer according to the manufacturer's recom-
mendation .
The tire pressure must be increased an addi t ional
3 PSI (0 .2 bar) for towing loads over 6,600 lbs
(3,000 kg) .
Winter tires shou ld be mounted on the vehicle
and on the trailer during winter temperatures .
Trailer towing
Outside mirrors
If you cannot see the traffic behind the trailer
with the standard exterior mirrors, then you
must attach additional exterior mirrors. Adjust
them so you have a sufficient visibility behind
you.
Exterior lighting

ing equipment on your trailer. Contact an author-
ized Audi dea ler or authorized Audi Service Facili-

ment on the hitched trailer.
The headl ight range cont rol adj usts automat ical-
ly to the light ran ge of the headlights .
Safety chains
Make sure the safety chains are correctly applied
when pulling a trailer . The cha ins should hang
enough so that the trailer can drive around
curves . Howeve r, they must not touch the
ground.
Air suspension
Applies to: vehicles with air suspension
The air suspens ion must be at the standard vehi -
cle he ight before you set the tongue we ight on
the tra iler and hitch the trailer ¢ @,
