!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 outlet (
page 291) in your vehicle when-
ever possible.
