0 co .... N ,..... N .... 0 0 :c ' A WARNING ,~
The sockets and the electrical accessories con­
nected to them only function when the igni­
tion is switched on . Incorrect usage can lead
to serious injuries or burns. To reduce the risk
of injur ies, never leave children unattended in
the vehicle with the vehicle key.
0 Note
- Never connect any accessories that provide
power (such as solar panels or battery
charger for the vehicle battery) to the ciga­ rette lighter. They can damage the vehicle
electrical system.
- To reduce the risk of damage to the sockets,
only use plugs that fit correctly.
115 volt socket
Appl ies to: vehicles with 115 volt socket
The 115 volt socket can be used when the igni­
tion is switched on
c::> ,& . When you push the con­
nector all the way into the socket, the child safe­
ty mechanism releases and current flows through
the socket .
Connectable devices
Elect rical devices can be connected to the 115
volt socket in the vehicle. The device connected
to the socket must not use more than 150 watts
of power (300 watts peak power). Check the
power usage of the connected device on the type
label.
LED on the socket
- Th e socket is ready for use when the LED is
green.
- There is a malfunction if the LED is blinking red.
The socket will switch off automatically due to
overcurrent or overheating. The socket will
switch on again automatically after a cool­
down period. Any devices that are connected
and switched on will activate again automati­
cally
c::> .&. .
Seats and storage
A WARNING
-The sockets and the electrical accessories
connected to them only function when the
ignition is switched on. Incorrect usage can
lead to serious injuries or burns. To reduce
the risk of injuries, never leave children un­
attended in the vehicle with the vehicle key.
- If devices or connectors that are heavy (for
example a power supply unit) are attached
directly to the socket, the holder can be­
come damaged, which increases the risk of inj ury.
- 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 if involved a crash.
- 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 sock­
et again.
- Devices connected to the vehicle behave dif­
ferently than when they are connected to a
regular power supply. Therefore, connected
devices can become hot during operation,
which can increase the risk of injury.
- There is a risk of injury when using adapters and extension cords, because the child safe­
ty on the socket is switched off and the
socket is powered with current.
- 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 injury, switch off any
connected electrical devices if the socket has switched off due to overheating.
0 Note
-Also read the operating manuals for the
connected devices.
- Do not connect any lamps that contain neon
tubes. Due to technical reasons, this can
cause malfunctions in the lamp.
- Do not connect any 230 volt devices to the
115 volt socket . The device can be dam­
aged. Check the permitted voltage of the
device according to the type label.
