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 > @.
118

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.

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 >

New tires or wheels
Audi recommends having all work
on tires or wheels performed by
an authorized Audi dealer or au-
thorized Audi Service Facility.
These facilities have the proper
knowledge and are equipped with
the required tools and replace-
ment parts.
>New tires do not yet have the
optimal gripping properties.
Drive carefully and at moderate
speeds for the first 350 miles
(500 km) with new tires.
> Only use tires with the same de-
sign, size (rolling circumfer-
ence), and as close to the same
tread pattern as possible on all
four wheels.
> Applies to: RS models: Only use
tires with the same design, size
(rolling circumference), and the
same tread pattern on all four
wheels.
>Do not replace tires individually.
At least replace both tires on the
same axle at the same time.
263

Wheels

Tire rotation
Rotating the tires regularly is rec-
ommended to ensure the tires
wear evenly. To rotate the tires,
install the tires from the rear axle
on the front axle and vice versa.
This will allow the tires to have
approximately the same length of
service life.
For unidirectional tires, make sure
the tires are installed according to
the running direction indicated on
the tire sidewall > page 291.
Hidden damage
Damage to tires and rims can of-
ten occur in locations that are hid-
den. Unusual vibrations in the ve-
hicle or pulling to one side may
indicate that there is tire damage.
Reduce your speed immediately.
Check the tires for damage. If no
damage is visible from the out-
side, drive slowly and carefully to
the nearest authorized Audi deal-
er or authorized Audi Service Fa-
cility to have the vehicle inspect-
ed.


Z\ WARNING
Tread that has worn too low or
uneven tread depths on the
tires can reduce driving safety.

266

This can increase the risk of an
accident because it has a nega-
tive effect on handling, driving
through curves, and braking,
and because it increases the
risk of hydroplaning when driv-
ing through deep puddles.

Determining correct load
Talis
Use the example below to calcu-
late the total weight of the pas-
sengers and luggage or other
things that you plan to transport
so that you can make sure that
your vehicle will not be overload-
ed.
Steps for Determining Correct
Load Limit
1. Locate the statement “THE
COMBINED WEIGHT OF OCCU-
PANTS AND CARGO SHOULD
NEVER EXCEED XXX KG OR XXX
LBS” on your vehicle’s placard
(tire inflation pressure label)
=> page 266, fig. 168.
2. Determine the combined
weight of the driver and pas-
sengers that will be riding in
your vehicle.
3. Subtract the combined weight
of the driver and passengers
from “XXX” kilograms or “XXX”
pounds shown on the sticker
=> page 266, fig. 168.
4. The resulting figure equals the
available amount of cargo and
luggage load capacity. For ex-
ample, if the “XXX” amount
equals 1400 lbs. and there will
be five 150 lbs. passengers in
your vehicle, the amount of
available cargo and luggage
load capacity is 650 lbs.
(1400-750 (5 x 150) = 650
lbs.)
5. Determine the combined
weight of luggage and cargo
being loaded on the vehicle.
That weight may not safely ex-
ceed the available cargo and
luggage load capacity calculat-
ed in Step 4.
6. If your vehicle will be towing a
trailer, load from your trailer
will be transferred to your vehi-
cle. Consult this manual to de-
termine how this reduces the
available cargo and luggage
load capacity of your vehicle.
>Check the tire sidewall
(=> page 257, fig. 165) to deter-
mine the designated load rating
for a specific tire.
Wheel bolts and rims
Wheel bolts
Wheel bolts must be clean and loosen/tighten
easily.
Rims
Rims with a bolted rim ring* or with bolted wheel
covers* consist of multiple pieces. These compo-
nents were bolted together using special bolts
and a special procedure. You must not repair or
disassemble them > A\.
