WARNING
•The charging cable must be grounded when in use. It is equipped with a cordwith a grounding conductor and agrounding plug. The plug must beinserted into an appropriate outlet that isproperly installed and grounded inaccordance with all local codes and ordi-nances and is not damaged in any way
• Children should be supervised when inthe vicinity of the charging cable when itis plugged in
• High voltage is present in your electricmeter housing and power distributionservice panel. Contact with high voltagecan cause death or serious personalinjury
• Do not use the charging cable if it isdamaged in any way
• Always position the charging cable sothat it will not be driven over, stepped on,tripped over or otherwise damaged, orcause personal injury
• Disconnect the charger from the wall out-let before cleaning it
• Never connect the charging cable to anextension cord or a multiple plug socket
•If the hybrid battery needs to be replaced, this may only be done by Volvo retailer orauthorized Volvo workshop
Also, refer to the manufacturer's instructions for using the charging cable and its compo-nents.
CAUTION
• Never unplug the charging cable from a 120-/240-volt socket while the hybridbattery is being recharged. This couldresult in damage to the socket. Alwaysstop the charging process before unplug-ging the charging cable
• To clean the charging cable, wipe it witha clean cloth dampened with water or amild detergent solution suitable for useon automobile paint. Do not use chemi-cals or solvents. Do not submerge thecharging cable

Hybrid charging cable circuit breakerThe charging cable has a circuit breaker that helps protect against current overloads andelectrical shocks.
If the charging cable's residual current breaker is triggered, the blue indicator light in the chargecoupler will not illuminate when the cable is plug-ged into a 120-/240-volt socket or the red indi-cator light will glow steadily. Have the socketchecked by a licensed electrician or try usinganother 120-/240-volt wall socket.
WARNING
• Charging the hybrid battery may only be done from approved, grounded 120-/240-volt sockets. If the electrical circuitor electrical socket's capacity is notknown, let a licensed electrician inspectthe electrical circuit's capacity. Using acharge level that exceeds the electricalcircuit's or electrical outlet's capacity maystart a fire or damage the electrical cir-cuit.
• The charging cable's residual currentbreaker helps protect the vehicle's charg-ing system but cannot ensure that an cur-rent overload will never occur.
• Never use visibly worn or damaged elec-trical sockets. Doing so could lead to firesor serious injury.
• Never connect the charging cable to anextension cord.
• Maintenance or replacement of the hybridbattery may only be performed by atrained and qualified Volvo service techni-cian.

Also, refer to the manufacturer's instructions for using the charging cable and its compo-nents.
Prior to chargingThe charging cable and any of its components should not be wet or submerged in any liquid. The charge module or its plug should not be exposed to direct sunlight. This could cause theunit's overheating protector to reduce or stop thehybrid battery charging process. Be sure the 120-/240-volt socket used has ade- quate current for charging electrically poweredvehicles. Have the socket checked by an licensedelectrician if you are uncertain.

Put the cover back in position and close the doorin reverse order.
Stopping hybrid battery charging
Stop hybrid battery charging by unlocking the vehicle, disconnecting the charging cable fromthe vehicle's charging socket and then unplug-ging the cable from the 120-/240-volt socket.
NOTE
Always unlock the vehicle to stop the charg- ing process before disconnecting the charg-ing cable from the vehicle's charging socketand then unplugging it from the120-/240-volt socket. The cable must be disconnected from the vehicle's charging socket before it isunplugged from the 120-/240-volt socketto help prevent damage to the chargingsystem.
Unlock the vehicle with the remote key.
Press the release button on the charge cou- pler to release it and disconnect the couplerfrom the vehicle's charging socket. Removethe cable from the vehicle. Put the socket'scover back in place and close the chargerdoor.
