shock and be seriously or even fatally injured. G
WARNING
Any device that you connect must have a suit- able plug and meet U.S. standards. Never pull at a cable to disconnect a plug from a 115 V
AC power socket. Never use a damaged con-
nection cable. The 115 V AC power socket
must never be connected to another 115 V AC power source. Do not use a converter with anearthed plug for the 115 V AC power socket.
This could cause serious injury to you and/or
other people. G
WARNING
If the 115 V AC power socket is damaged or
pulled out of the trim, do not use or touch the 115 VAC power socket. The use of a 115 VAC
power socket that has been damaged or
pulled out of the trim could cause serious
injury to you or others. 115 V power socket
:provides an AC volt-
age of 115 Vso that small electronic devices
can be connected. These devices, such as
games consoles, chargers and laptops,
should not consume more than a maximum of 150 W altogether.
Requirements for operation of these devices:
R the 12 V sockets in the rear compartment
and the cargo compartment are opera-
tional (Y page 257).
R the plug of the electronic device is plugged
into 115 V power socket :.R
the on-board power supply is within a per-
missible voltage range.
R the electronic device's maximum power
output does not exceed 150 W.
X Open flap =.
X Switch on the ignition.
X Insert the plug of the electronic device into
115 V power socket :.
Indicator lamp ;lights up.
If indicator lamp ;does not light up,
please read the section on malfunctions.
X To turn off: disconnect the plug from 115 V
power socket :.
Ensure that you do not pull on the cord.
X Close flap =.
Possible causes of malfunctions:
R the on-board power supply is not within a
permissible voltage range.
R the temperature of the DC/AC converter is
temporarily too high.
R some small electronic devices have a con-
stant nominal power of less than 150 W,
but a very high switch-on current. In that
case, there is a possibility that these devi-
ces will not function properly as 115 V
socket :is not able to provide a high
enough current.
X If indicator lamp ;still does not light up,
contact a qualified specialist workshop. mbrace
