!The lighter socket can be used to ac-
commodate 12V DC electrical acces-
sories (up to a maximum of 85 W)
designed for use with the standard
“cigarette lighter” plug type. Keep in
mind, however, that connecting acces-
sories to the lighter socket (for exam-
ple extensive connecting and
disconnecting, 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) posi-
tion, or the lighter may pop out too ear-
ly with the lighter not hot enough.
To help avoid damaging the cigarette
lighter socket, we recommend con-
necting 12V DC electrical accessories
designed for use with a standard “ciga-
rette lighter” plug type to the 12V pow-
er outlets in your vehicle whenever
possible.
iThe power outlet can be used to
accommodate 12V DC electrical ac-
cessories (e.g. air pump, auxiliary
lamps) up to a maximum of 180 W.
An additional power outlet is located on
the left side in the cargo compartment.
