!
The lighter socket can accommodate 12V
DC electrical accessories (up to a maximum of
85 W) designed for use with the standard “ciga-
rette lighter” plug type. Keep in mind, however,
that connecting accessories to the lighter socket
(for example extensive connecting and discon-
necting, or using plugs that do not fit properly)
can damage the lighter socket. With the socket
damaged, the lighter may no longer be able to be
placed in the heating (pushed-in) position, or the
lighter may pop out too early with the lighter not
hot enough.
To help avoid damaging the cigarette lighter
socket, we recommend connecting 12V DC elec-
trical accessories designed for use with the stan-
dard “cigarette lighter” plug type to the
12V power outlets (
컄
page 314) in your vehicle
whenever possible.
!
The cigarette lighter is not designed for use
with the electric air pump (
컄
page 499). Use a
power outlet (
컄
page 314) for electric air pump
operation.
i
If the engine is off, and the cigarette lighter
is being used extensively, the vehicle battery
may become discharged.
!
If you use all power outlets in the vehicle,
make sure that the maximum current drawn
does not exceed 55 A.
i
The power outlets can be used to
accommodate 12V DC electrical accessories
(e.g. air pump, auxiliary lamps) up to a maximum
of 240 W.
If the engine is off and the power outlets are
being used extensively, the vehicle battery may
become discharged.
i
You can use the power outlets, except for
the power outlet in the front center console,
even if the ignition is switched off.
An emergency shut-off feature ensures that the
vehicle’s electrical voltage does not fall below a
minimum level. If the voltage drops to this mini-
mum level, the power outlets are automatically
switched off. This ensures that enough power
remains to start the engine.
