HYBRID INFORMATION

383
Charging current Charging current is used to charge the hybrid battery and precondition the vehicle. Charg-ing is performed by connecting a chargingcable between the vehicle's charging socketand a 120/240 V electrical socket (alternat-ing current).
When the charging cable is activated, a mes- sage will be displayed in the instrument paneland an indicator light in the vehicle's chargingsocket will illuminate. Charging current is pri-marily used for battery charging, but is alsoused for preconditioning. The vehicle's startbattery is charged along with the hybrid bat-tery.
CAUTION
Never detach the charging cable from the 120/240 V outlet (AC, alternating current)while charging is in progress – the120/240 V outlet could be damaged insuch circumstances. Always interruptcharging first and then disconnect thecharging cable – first from the vehicle'scharging socket and then from the120/240 V outlet.
NOTE
In extremely cold or hot weather, part of the charging current is used to heat/cool the hybrid battery and the passen-ger compartment, resulting in a longercharging time.
The charging time is longer if precondi-tioning has been selected. The timerequired depends primarily on theambient temperature.
FuseThere are normally several 120/240 V power consumers in one fuse circuit, which meansthat more than one power consumer (e.g.lighting, vacuum cleaner, electric drill, etc.)may use the same fuse.

Jump starting using another battery If the start battery is discharged, current from another battery can be used to start the vehi-cle.
Jumper cable connecting points.
CAUTION
The charging point of the vehicle is only intended for jump starting the vehicle inquestion. The charging point is notintended for jump-starting another vehicle.Using the charging point to start anothervehicle could cause a fuse to blow, whichwould cause the charging point to stopworking.
If a fuse has blown, 12 V Battery Fuse failure
Service required will be displayed in the instrument panel. Volvo recommends contact- ing an authorized Volvo workshop. To avoid short circuits or other damage, the following steps are recommended when jumpstarting the battery:
1. Put the ignition in mode
0.
2. Make sure the auxiliary battery (the bat- tery used to jump start the discharged battery) has a voltage of 12 volts.
3. If the auxiliary battery is in another vehicle, turn off that vehicle's engine and makesure that the vehicles are not touchingeach other.
4. Clamp the red jumper cable onto the auxil- iary battery's positive (+) terminal (1).
CAUTION
Connect the jump cable carefully to pre- vent short circuits with other componentsin the engine compartment.
5. Fold back the cover over your vehicle'spositive (+) jump start terminal (2).
6. Clamp the other end of the red jumper cable to your vehicle's positive (+) jump start terminal (2).
7. Clamp the black jumper cable onto the auxiliary battery's negative (-) terminal (3). 8. Clamp the other end of the black jumper
cable to your vehicle's negative (-) groundpoint (4).
9. Make sure the jumper cables are securely attached to help prevent sparks whilejump starting.
10. Start the engine of the assisting vehicle and let it run for a few minutes at a higheridling speed than normal, about1500 rpm.

Engine compartment overview
This overview shows some service-related components.
Some of the components included in the vehi- cle's electric drive system are located in theengine compartment. Exercise caution whenaccessing the engine compartment and onlytouch what is required for normal mainte-nance.
WARNING
Orange wiring may only be handled by qualified personnel.
WARNING
A number of electrical components in Twin Engine Plug-in Hybrid vehicles use high-voltage current and can be extremely dan-gerous if handled incorrectly.
Do not touch anything that is not clearly described in this Owner's Man-ual.
Be careful when checking/filling fluidsin the engine compartment.
The layout of the engine compartment may vary depending on model and engine variant.
Coolant expansion tank
Brake fluid reservoir (located on the driv- er's side)
Washer fluid filler pipe 12
Fusebox
Air filter
Engine oil filler pipe
WARNING
Bear in mind that the cooling fan (located at the front of the engine compartmentbehind the radiator) may start or continuerunning automatically up to about6 minutes after the engine is turned off. Always entrust engine washing to a work- shop – an authorized Volvo workshop isrecommended. If the engine is hot, there isa risk of fire.
WARNING
The ignition system works with extremely high and dangerous voltages. The vehicleelectrical system should always be in igni-tion mode
0 when work in being per-
formed in the engine compartment. Do not touch any spark plugs or ignition coils when the vehicle electrical system isin ignition mode II or when the engine is
warm.

Positive connection point
Negative connection point
CAUTION
It is not possible to charge another vehi- cle's battery by supplying current throughthe charging points. Using the chargingpoints to charge another vehicle's batterycould cause a fuse to blow, which wouldcause the charging points to stop working.
CAUTION
Only a modern battery charger with con- trolled charge voltage should be used tocharge the starter battery. The rapid charg-ing function should not be used as thiscould damage the battery.
NOTE
If both the starter battery and the hybrid battery are discharged, both batteries
must be charged. In such cases, it is notpossible to charge only the hybrid batteryfirst. The starter battery must have a certain level of charge for it to be possible tocharge the hybrid battery.
CAUTION
Failure to observe the following could cause the infotainment energy save modeto temporarily stop working and/or a mes-sage in the driver's display regarding thestate of charge of the starter battery maybe temporarily incorrect after an externalstarter battery or battery charger has beenconnected:
The negative battery terminal of thevehicle's starter battery must
never be
used to connect an external starterbattery or battery charger – only thevehicle's negative charging pointshould be used as a grounding point.
