FUSES
General Information
The fuses protect electrical systems against excessive current. When a device does not work, you must check the electrical circuit inside the fuse for a break/melt.
Also please be aware that using power outlets for extended periods of time with the engine off may result in vehicle battery discharge.
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 property damage.
- Before replacing a fuse, make sure that the ignition is off and that all the other services are switched off and/or disengaged.
- If the replaced fuse blows again, contact an authorized dealer.
- If a general protection fuse for safety systems (air bag system, braking system), power unit systems (engine system, gearbox system), steering system or Body Control Module (BCM) blows, contact an authorized dealer.

BULB REPLACEMENT
General Information
- Before you replace a bulb, check the contacts to be sure they are not oxidized.
- Replace the bulbs with the same type and wattage.
- After replacing a light bulb, always check the correct orientation.
- Before replacing a bulb that is not functioning, check that the fuse is intact.
NOTE:
Lens fogging can occur under certain atmospheric conditions. This will usually clear as atmospheric conditions change to allow the condensation to change back into a vapor. Turning the lamps on will usually accelerate the clearing process.
