Trailer towing

Trailer towing
Driving with a trailer
er else)
Your vehicle is primarily intended for transport-
ing people and luggage. However, if you drive
with a trailer, follow the technical requirements,
the operation and driving tips, and the legal reg-
ulations.
Driving with a trailer affects the vehicle's energy
usage, performance, and wear. It also requires
higher concentration from the driver.

ZA\ WARNING
Do not transport any people in a trailer due to
the risk of fatal injury.
Technical requirements
Trailer hitch

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.
Engine cooling system
Driving with a trailer means a higher load on the
engine and the cooling system. The cooling sys-
tem must be designed for additional load and
contain enough coolant > @.
120

ZA\ WARNING
— Never mount a "weight-distributing" or
"load-balancing" trailer coupler as the trailer
hitch. The vehicle was not designed for
these types of trailer hitches. The trailer
hitch can malfunction and the trailer can
break off from the vehicle.
— If the trailer is equipped with electronic
brakes, these brakes cannot be activated by
a factory-installed control system, which in-
creases the risk of an accident.
—To reduce the risk of injury, always remove
the ball hitch mount if no trailer is mount-
ed
@) Note
Longer inclines cannot be driven without a
suitable cooling system, especially if the out-
side temperatures are high. Otherwise, this
increases the risk of engine damage.
ey emia aCe
Towing capacity

The permitted towing capacity must not be ex-
ceeded under any circumstances > page 314.
You can drive up larger inclines if you are not us-
ing the maximum towing capacity.
The specified towing weights only apply at eleva-
tions up to 3,200 feet (1,000 m) above sea level.
As the elevation increases, the engine power de-
creases due to the decreasing air pressure. This
reduces the hill climbing ability and towing ca-
pacity. For every additional 3,200 feet (1,000 m),
the maximum permitted towing weight must be
reduced by approximately 10%. The permitted
towing weight is the combined weight of the
(loaded) vehicle and the (loaded) trailer.
Tongue weight
The maximum permitted tongue weight of the
trailer drawbar on the trailer hitch ball head must
not be exceeded.
For driving safety, Audi recommends always us-
ing
the maximum permitted tongue weight, but
do not exceed this weight. Distributing the cargo >

Trailer towing

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 114.
You can also increase ground clearance by select-
ing the Audi drive select* offroad or allroad
modes > page 113.
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.
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.
— Avoid driving with a trailer during the vehi-
cle break-in period.
Driving with a trailer
Driving with a trailer requires extra caution.
122
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.
Downshift before driving on hills to utilize the en-
gine braking effect > 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.
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 14. Shift to a higher gear in a timely man-
ner.

ZA\ 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.

to cool down sufficiently.
— Maintain enough distance when you are re-
moving the oil drain plug. While doing this,
keep your forearm parallel to the ground to
reduce the risk of hot oil dripping down your
arm.
— Drain the oil into a container designed for
this purpose that is large enough to hold the
full amount of oil in your engine.
— Engine oil is poisonous. Always store out of
reach of children.
— Prolonged contact of used engine oil with
the skin may cause skin damage. Always
wash oil off immediately with soap and wa-
ter to protect your skin.

@) Note

Additives may cause engine damage that is
not covered by your New Vehicle Limited War-
ranty.
@ For the sake of the environment
— Before changing the engine oil, make sure
you can dispose of the used engine oil cor-
rectly.
— Engine oil must always be disposed of cor-
rectly. Do not dump it in the yard, in the for-
est, or in open water, river channels, or sew-
ers.
— Have your used engine oil recycled by bring-
ing it to a used oil collection site or contact
a gas station.
Cooling system
The engine cooling system is filled with a mixture
of purified water and coolant additive at the fac-
tory. This coolant must not be not changed.
The coolant level is monitored using the || indi-
cator light. However, occasionally checking the
coolant level is recommended.

Coolant loss usually indicates that there is a leak.
Immediately drive your vehicle to an authorized
Audi dealer or authorized Audi Service Facility
and have the cooling system inspected. If the
cooling system is not leaking, coolant loss can re-
sult from the coolant boiling due overheating
and then being forced out of the cooling system.

ZA\ WARNING
— The engine compartment in any vehicle is a
potentially dangerous area. Stop the engine,
switch the ignition off, and allow the engine
to cool before working in the engine com-
partment. Always follow the information
found in > page 245, General information.
— Never open the hood if you can see or hear
steam or coolant escaping from the engine
compartment. This increases the risk of
burns. The cooling system is under pressure.
When you no longer see or hear steam or
coolant escaping, you may open the engine
compartment with caution.
— When working in the engine compartment,
remember that the radiator fan can switch
on even if the ignition is switched off, which
increases the risk of injury.
— Coolant additive and coolant can be danger-
ous to your health. For this reason, store the
coolant in the original container and away
from children. There is a risk of poisoning.
