WARNING!(Continued)
Seat belt assemblies must be replaced after a colli-
sion if they have been damaged (i.e., bent retractor,
torn webbing, etc.).
FUSES
WARNING!
•When replacing a blown fuse, always use an
appropriate replacement fuse with the same amp
rating as the original fuse. Never replace a fuse
with another fuse of higher amp rating. Never
replace a blown fuse with metal wires or any
other material. Failure to use proper fuses may
result in serious personal injury, fire and/or prop-
erty damage.
• Before replacing a fuse, make sure that the igni-
tion is off and that all the other services are
switched off and/or disengaged.
• If the replaced fuse blows again, contact an au-
thorized dealer.
(Continued)
WARNING! (Continued)
•If a general protection fuse for safety systems (air
bag system, braking system), power unit systems
(engine system, gearbox system) or steering sys-
tem blows, contact an authorized dealer.
Interior Fuses
The interior fuse panel is part of the Body Control
Module (BCM) and is located on the driver’s side under
the instrument panel.

VEHICLE STORAGE
The preferred way of storing your vehicle for a long
period of time is to leave it attached to a Level 1 or Level
2 charger. The vehicle has a wake-up feature that will
wake the system every 3 weeks and do a maintenance
charge on the 12 Volt battery and also top off the high
voltage battery if necessary. Anytime you store your vehicle, or keep it out of service
(e.g., vacation) for two weeks or more, run the air
conditioning system at idle for about five minutes in the
fresh air and high blower setting. This will ensure
adequate system lubrication to minimize the possibility
of compressor damage when the air conditioning sys-
tem is started again.
