Grounding instructions
Audi charging systems must be grounded. If it
should malfunction or break down, grounding
provides a path of least resistance for electric
current to reduce the risk of electric shock. Audi
charging systems are equipped with a cord hav-
ing an equipment grounding conductor and a
grounding plug. The plug must be plugged into
an appropriate outlet that is properly installed
and grounded in accordance with all local codes
and ordinances.

ZA WARNING
Improper connection of the equipment-
grounding conductor is able to result in a risk
of electric shock. Check with a qualified elec-
trician or serviceman if you are in doubt as to
whether the product is properly grounded. Do
not modify the plug provided with the product
— if it will not fit the outlet, have a proper out-
let installed by a qualified electrician.

Trailer towing

— Secure objects so that they do not slide.
— Utilize the maximum permitted tongue weight
if possible.
Tires
Set the tire pressure on your vehicle for a “full
load”; see the tire pressure sticker > page 251. 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.
Outside mirrors
Make sure that you can also observe the traffic
area behind the vehicle using the exterior mir-
rors, and use additional exterior mirrors if neces-
sary. Adjust the additional exterior mirrors so
that you have a sufficient visibility behind the ve-
hicle. Follow the local legal regulations for instal-
ling additional exterior mirrors.
Exterior lighting
Follow the legal regulations for lighting on your
trailer that are applicable in the country where
you are operating the vehicle. Contact an author-
ized Audi dealer or authorized Audi Service Facili-
ty for more information.
Before you start driving, check all lighting equip-
ment on the trailer while it is hitched to the vehi-
cle.
The headlight range control automatically ad-
justs the light range of the headlights.
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.
Air suspension
Applies to: vehicles with air suspension
The Audi drive select* comfort mode > page 102
must be selected before you adjust the tongue
weight on the trailer and hitch the trailer >@,
=> page 103.
The air suspension trailer mode must be switched
on.
Applies to MMI: select on the home screen: VE-
HICLE > Settings & Service > Air suspension:
trailer.
Switch trailer mode off again when you are no
longer towing a trailer.
For vehicles with a factory-installed trailer hitch,
the air suspension trailer mode will automatically
switch on if you connect the trailer connector to
the socket.
When using rear carrier systems that are mount-
ed directly on the trailer hitch ball head, you can
also switch trailer mode off manually.
If you must drive on roads that are in poor condi-
tion, you can raise the vehicle again after hitching
the trailer or after adjusting the tongue weight
=> page 103.
You can also increase ground clearance by select-
ing the Audi drive select* offroad or allroad
modes > page 102.
Vehicle levels below the values set in the comfort
level will no longer be available, even if you are
lowering the vehicle manually.

ZA WARNING
Applies to: vehicles with air suspension
— Never turn off trailer mode while driving
when a trailer is hitched, because then the
restrictions for controlling the vehicle level
will be turned off.
— Driving with a trailer on unpaved roads when
the vehicle is raised may change the vehicle
handling. Adapt your speed.
— Note that the vehicle will lower automatical-
ly at certain speeds if you have lifted the ve-
hicle manually.
@) Note
— Applies to: vehicles with air suspension: Se-
lect the Audi drive select* comfort mode.

127

Trailer towing

Otherwise, the tongue load specified for
your vehicle will no longer be applicable.
— Attachments retrofitted on the vehicle may
cause damage, especially on the trailer
hitch ball head. In cases of damage, have
the function checked by an authorized Audi
dealer or authorized Audi Service Facility.
@) Tips
— 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.
Driving with a trailer
Driving with a trailer requires extra caution.
Speed
Adhere to the legal speed limits. Follow the legal
regulations that are applicable in the country
where you are operating the vehicle.
As the speed increases, the driving stability of
the trailer decreases. Therefore you should not
exceed the maximum legal speed limit when
there are unfavorable road, weather, and/or wind
conditions. This especially applies when driving
downhill.
Hill
When you start driving uphill or downhill, trailers
may tilt or sway sooner than when driving ona
level surface. If small swaying movements have
already occurred, you can stabilize the trailer by
firmly braking immediately. Never attempt to
“straighten out” the trailer by accelerating.
reduce the speed and use the recuperation brak-
ing effect > page 94 to relieve the brakes > A\.
Brakes
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.
128


AN WARNING
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.
