Safety Precautions 1-3
NOTE
When the ignition switch is set to the OFF
position, the electrical components are not
energized except for the MCM (Master
Chassis Module), the battery equalizer, the
preheater system and some electronic
modules; which are energized during 15
minutes after the ignition has been set to the
OFF position. Prior to working on one of
these electrical components, set the battery
master switch in
compartment to the OFF position. If the
vehicle will not be operated for a long period
(more than 2 weeks), it is recommended, in
order to prevent the
discharging, to trip the main circuit breakers
located in the main power compartment to
stop the small current drawn by the radio
preset station memory, the MCM memory
and the instrument cluster clock. Note that
the radio station presets will be erased,
same thing for the diagnostic codes history
and the instrument cluster clock will have to
be reset.
