WARNING
Any device that you connect must have a
suitable 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
connection cable. The 115 V AC power socket
must never be connected to another 115 V
AC power source. Do not use a converter with
an earthed 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 V AC power socket. The use of a 115 V
AC 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
voltage of 115 V so 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
operational ( Y page 271).
R the

plug of the electronic device is plugged
into 115 V power socket :.
R the on-board power supply is within a
permissible 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
constant nominal power of less than
150 W, but a very high switch-on current.
In that case, there is a possibility that these
devices will not function properly as 115 V
socket : is not able to provide a high
enough current.
