Power sources
When the ignition is switched on, you may be
able to use multiple power sources for external
devices, depending on the vehicle equipment.
12 volt sockets
You can connect electrical accessories to the 12
volt sockets. The power usage must not exceed
120 watts.
The 12 volt sockets are labeled with the 12V
symbol. They are located in the front center con-
sole, in the rear* and on the side trim panel in the
luggage compartment*.
USB ports
Applies to: vehicles with USB port
You can charge mobile devices using the USB
ports. The USB ports are labeled with the «<> or
(4 symbol or CHARGE ONLY.
115 volt socket
Applies to: vehicles with 115 volt socket
The socket is located in the center console in the
rear and can be used for electrical devices > A\.
The power usage must not exceed 150 watts.
When you push the device connector all the way
into the socket, the child safety mechanism re-
leases and there is electric current.
—If the LED on the socket is green or flashes
slowly, then the socket is ready for use.
—If the LED is red and flashes quickly, there is a
malfunction in the connected device or the
socket is too hot. The socket will switch off for
safety reasons. To reactivate the socket, remove
the device connector. Connect the device after
correcting the malfunction or reconnect after a
brief cool-down period.

— Incorrect usage can lead to serious injuries
or burns. To reduce the risk of injuries, never
leave children unattended in the vehicle
with the key.


Z\ WARNING
Applies to: vehicles with 115 volt socket
—To reduce the risk of fatal injury, do not in-
sert any conductive objects, such as knitting
needles, into the contacts on the socket.
—To reduce the risk of fatal injury, do not spill
any fluids on the socket. Should any mois-
ture enter the socket, make sure that it has
dried out completely before using the socket
again.
— If devices or connectors that are heavy (such
as a power supply unit) are attached directly
to the socket, the holder can become dam-
aged, which increases the risk of injury.
— Using adapters and extension cables in-
creases the risk of injury because they over-
ride the safety devices for the socket.
—To reduce the risk of injury, remove the con-
nector of the connected device if the socket
has switched off due to a malfunction.


Z\ WARNING
—To reduce the risk of fatal injury, store all
connected devices securely when driving so
that they do not move around inside the ve-
hicle when braking or in the event of an acci-
dent.

@) Note
— Read the operating manuals for the con-
nected devices.
—To reduce the risk of damage to the vehicle
electrical system, never attempt to charge
the vehicle battery by connecting accesso-
ries that provide power to the power sour-
ces.
— Do not connect any device whose network
class (voltage) does not match the network
class designed for the socket.
— Disconnect the connectors from the power
sources carefully to reduce the risk of dam-
aging them.
(i) Tips
Applies to: vehicles with 115 volt socket
— Devices that are not shielded or devices near
the rear window antenna can cause mal-
functions in the radio, TV, or vehicle electri-
cal system.

Stowing and using

— Holders for a notepad and a pen in the glove
compartment
— Storage compartments in the door trim panel
— Net in the front passenger's footwell
— Storage compartments under the center arm-
rest
— Compartments on the backrests of the front
seats
— Garment hooks in the rear
— Cell phone holder in the right rear door
— Bag hooks in the luggage compartment
— Net in luggage compartment
— Umbrella holder
> Stow heavy luggage as far forward in the lug-
gage compartment as possible.
> Use non-elastic cords attached to the tie-downs
to secure objects.


ZA WARNING
— To reduce the risk of injury, make sure all
storage compartments are always closed
while driving.
— Loose objects can be thrown around the ve-
hicle interior during sudden driving or brak-
ing maneuvers, which increases the risk of
an accident. Store objects securely while
driving.
— Only use the storage compartments in the
door trim panels to store small objects that
will not stick out of the compartment and
impair the function of the side airbags.
— Only lightweight clothing should be hung
from the garment hooks in the vehicle. Do
not use clothes hangers to hang clothing.
The pockets of the clothing must not con-
tain any heavy, breakable, or sharp-edged
objects. This could impair the effectiveness
of the side curtain airbags.
— Make sure your view toward the rear is not
blocked, for example by hanging clothing or

objects in the vehicle.

Luggage compartment
General information
All pieces of luggage or objects must be securely
fastened in the luggage compartment. Note the
following to maintain good vehicle handling:
> Distribute the load evenly in the luggage com-
partment.
100

ZX WARNING
— Loose objects can be thrown around the ve-
hicle interior during sudden driving or brak-
ing maneuvers, which increases the risk of
an accident. Always stow objects securely in
the luggage compartment and secure them
at the tie-downs. Use straps suitable for
heavy objects.
— If pieces of luggage or objects are secured
to the tie-downs with unsuitable or dam-
aged straps, this can increase the risk of in-
jury during braking maneuvers or accidents.
— When transporting heavy objects, the vehi-
cle characteristics will change due to the
shift in the center of gravity, which increases
the risk of an accident. You may need to
adapt your driving style and speed to the
current conditions.
— The cargo net is only strong enough to se-
cure light objects. Heavy objects are not ade-
quately secured. Attempting to secure heavy
objects increases the risk of injury.
— Never exceed the permitted axle and load
and vehicle weight > page 342.
— Never secure a child safety seat to the tie-
downs.
— Never leave your vehicle unattended, espe-
cially if the luggage compartment lid is
open. Children could enter the luggage com-
partment and close the luggage compart-
ment lid from the inside. This creates the
risk of fatal injury, since the children would
be locked in and may not be able to escape
by themselves.
— Do not allow children to play in or on the ve-
hicle. Close and lock the luggage compart-
ment lid as well as all other doors when you
leave the vehicle.
— Never transport passengers in the luggage
compartment. Every passenger must be cor-
rectly secured with the safety belts in the
vehicle > page 82.

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.

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).

If you cannot shift out of “P”, for example be-
cause the vehicle has no power, you may need to
use the emergency release for the parking lock
=> page 116.
Selecting the driving program
Various driving programs can be selected when in
the “D” gear. The programs influence when the
transmission shifts and how the accelerator ped-
al responds.
The selected driving program is displayed in the
instrument cluster.
— D (Drive): normal driving mode
— S (Sport): sporty driving mode
If you select the Dynamic mode in Audi drive se-
lect*, the “S” driving program will be activated.
