Stowing and using

Depending on the equipment, the refrigerator
may be located in the rear behind the center arm-
rest or the sunshade. It refrigerates or freezes
only when the ignition is switched on.
The maximum load capacity is 5.5 lbs (2.5 kg).
Opening and closing
> Pull the release lever (2) to open the refrigera-
tor.
> To close the refrigerator, push the cover back
until it clicks into place.
Switching on and off
> Press the button (@) to switch the cooling func-
tion on or off.
>» Press the button (8) to switch the freezer func-
tion on or off.


Z\ WARNING
— Never overfill the refrigerator. Leave it
closed while driving. There is a risk of injury
in the event of a collision or sudden braking.
— Never store flammable fluids, gas contain-
ers, or similar objects in the refrigerator due
to the risk of an explosion. This also applies
to goods and products that can emit volatile
or flammable gases.
— Fluids may freeze at temperatures of 32° F
(0 °C) and lower. Glass containers could ex-
plode, increasing the risk of injury.

@) Note
The ventilation openings for the refrigerator
are at the rear panel trim panel in the luggage
compartment and must not be covered.
@ Tips
— When the temperature in the luggage com-
partment is high, there may only be a limit-
ed cooling effect. The refrigerator will auto-
matically switch off if the temperature in
the luggage compartment exceeds 131° F

Roof rack
General information
Applies to: vehicles with roof rack mount

B4H-0334

Fig. 94 Roof: mounting points
If luggage or cargo is to be carried on the roof,
you must observe the following:
— These roof racks are the basis for a complete
roof rack system. Only roof racks that are suita-
ble for your vehicle may be used. Roof racks and
attachments from the Audi Genuine Accesso-
ries program are recommended.
— Make sure the roof rack is mounted on the vehi-
cle only at the specified locations > fig. 94.
— Note the permitted axle load, permitted total
weight, and permitted roof load of your vehicle
=> page 342. The roof load is the total of the
weight of the roof rack, the attachments and
the cargo you are carrying. However, you must
also note the permitted load of the carrier sys-
tem being used.

ZA WARNING
— Follow the installation instructions provided
with the roof rack system. If you do not se-
cure the roof rack system and objects on the
roof correctly, they could come loose from
the vehicle and cause an accident.
— The risk of an accident increases when using
a roof rack system, because it changes the
driving characteristics by shifting the center
of gravity and/or the increasing the surface
area exposed to wind. You may need to
adapt your driving style and speed to the
current conditions. We recommend that you
do not drive faster than 80 mph (130
km/h).

Trailer towing

Trailer towing
Driving with a trailer
General information
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.

Z\ 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 > @.
CG) 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.
Operating instructions
Towing capacity
Your vehicle can only be operated with class 1 or
class 2 trailers.
Load distribution
Poor cargo load and distribution can negatively
impact vehicle handling. Load the trailer based
on the following criteria as much as possible:
— Store objects in the vehicle luggage compart-
ment, if possible. The vehicle should always
carry the heaviest possible load and the trailer
should have the lightest possible load.
— Distribute the load in the trailer so that the
heavy objects are as close to the axle as possi-
ble.
— 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 299. 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
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
Follow the legal regulations for lighting on your
trailer that are applicable in the country where

exceed 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 290, fig. 189) 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. You will need a special adapter to loosen
the anti-theft wheel bolts* > page 319.
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\.

ZA WARNING
Wheel bolts that are tightened or repaired in-
correctly can become loose and result in loss
of vehicle control, which increases the risk of
an accident. For the correct tightening specifi-
cation, see > page 322, Finishing.
— Always keep the wheel bolts and the threads
in the wheel hub clean and free of grease.
— Only use wheel bolts that fit the rim.
— Always have damaged rims repaired by an
authorized Audi dealer or authorized Audi
Service Facility. Never repair or disassemble

rims yourself, because this increases the risk
of
an accident.
Loose wheel warning
Applies to: vehicles with loose wheel warning

Within the limits of the system, the loose wheel
warning in the instrument cluster warns you if
one or more wheels are loose.
Using the ABS sensors, the loose wheel warning
system compares the vibration characteristics of
the individual tires. If one or more wheels are
loose, it will be indicated in the instrument clus-
ter display with the fi indicator light and a mes-
sage. If only one wheel is affected, the location
of that wheel will be indicated.
Messages
fi Wheel bolts loose. Please safely stop the ve-
hicle and check all wheel bolts!
Loose wheel warning for at least one wheel > A\.
Check the wheel bolts on all wheels with the
wheel wrench (vehicle tool kit). Have the tighten-
ing specification checked as soon as possible with
a torque wrench. Drive carefully until then. For
the correct tightening specification, see
=> page 322, Finishing.
fi Wheel assessment active. Please continue
driving carefully
After this message appears and you have checked
the wheel bolts, the assessment phase begins
when the vehicle is in motion. This may take sev-
eral minutes.

owner's manual
There is a system malfunction. Drive immediately
to an authorized Audi dealer or authorized Audi
Service Facility to have the malfunction repaired.

ZA\ WARNING
Wheel bolts that are tightened incorrectly can
become loose and result in loss of vehicle con-
trol, which increases the risk of an accident.
