Power outlets

!

The lighter socket can accommodate

12V DC electrical accessories (up to a maximum
of 180 W) designed for use with the standard
“cigarette lighter” plug type. Keep in mind, how-
ever, that connecting accessories to the lighter
socket (for example extensive connecting and
disconnecting, or using plugs that do not fit prop-
erly) can damage the lighter socket. With the
socket damaged, the lighter may no longer be
able to be placed in the heating (pushed-in) posi-
tion, 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 (

page 287) in your vehicle

whenever possible.

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, the battery may become dis-
charged if used for long periods of time.

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 re-
mains to start the engine.
