the lighter socket (for example extensive
connecting and disconnecting, or using
plugs that do not fit properly) can damage
the lighter socket. With the socket
damaged, the lighter may not function
properly any longer.

to prevent the vehicle's on-board voltage
in its socket
from dropping below a minimum level. If
the on-board voltage drops to this
minimum level, the power outlets are
automatically switched off, to help
preserve engine starting power.

make sure that the maximum current
drawn does not exceed 55 A.
! The power outlets in the passenger
footwell and cargo compartment are not
designed for use with the electric air pump.
Use the power outlet in the second-row
footwell for electric air pump operation.
The power outlets can be used to
accommodate 12V DC electrical accessories
(e.g. mobile phone chargers, auxiliary lamps)
up to a maximum of 20 A (240 W).
If the engine is off and the power outlets are
being used extensively, the vehicle battery
may become discharged.
