SmartKey from the ignition lock. Always take
the SmartKey with you and lock the vehicle.
Do not leave children unattended in the
vehicle, even if they are secured in a child
restraint system, or with access to an
unlocked vehicle. A child's unsupervised
access
to a vehicle could result in an accident
and/or serious personal injury. The children
could:
R injure themselves on parts of the vehicle
R be seriously or fatally injured through
excessive exposure to extreme heat or cold
R injure themselves or cause an accident with
vehicle equipment that can be operated

direct sunlight. The child restraint system's
metal parts, for example, could become very
hot, and the child could be burned on these
parts.

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

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
