NOTE
If the starter battery becomes discharged too many times, it will shorten its servicelife. The service life of the starter battery is affected by several factors, such as drivingconditions and climate. The startingcapacity of the battery reduces graduallyover time. The battery must therefore berecharged if the vehicle is not used or along period of time or if it is only drivenshort distances. Severe cold further limitsthe starting capacity. To keep the starter battery in a good condi- tion, the vehicle should be driven at least15 minutes per week or the battery shouldbe connected to a battery charger withautomatic trickle charging. A starter battery that is always kept fully charged has the maximum service life.Location
The start battery is located in the cargo compart- ment.
WARNING
If the starter battery is disconnected, the function for automatic opening and closingmust be reset to function correctly. A resetis required in order for the pinch protectionto work.
CAUTION
On certain models, the battery is secured with a tensioning strap. Make sure that thetensioning strap is always securely tight-ened.

Hybrid battery The vehicle's electric motor is powered by a rechargeable, maintenance-free, lithium-ionhybrid battery.
NOTE
The vehicle cannot be started if the hybrid battery is discharged.
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.
WARNING
Hybrid battery replacement may only be performed by a workshop – an authorizedVolvo workshop is recommended.
CoolantThe hybrid battery's cooling system has its own expansion tank.
CAUTION
Filling the hybrid battery coolant should only be performed by a workshop – anauthorized Volvo workshop is recom-mended.
Specifications for hybrid batteryType: Lithium-ion
Power reserve: 11.6 kWh.
NOTE
The capacity of the hybrid battery decrea- ses with age and use, which could result inincreased use of the combustion engine,leading to higher fuel consumption andreduced electric motor range.

Fuses and fuseboxes All electrical functions and components are protected by a number of fuses in order toprotect the vehicle's electrical system fromdamage by short circuiting or overloading.
WARNING
Never use a foreign object or a fuse with a higher amperage than that specified toreplace a fuse. This could cause significantdamage to the electrical system and possi-bly lead to a fire.
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 the vehicle's Owner's Manual.
If any electrical component or function is not responding, the component may have blown a fuse due to temporary overload. If the same fuse blows repeatedly, there may be a prob-lem with the component. Volvo recommendscontacting an authorized Volvo workshop tohave the component checked.

Replacing fuses
All electrical functions and components are protected by a number of fuses in order toprotect the vehicle's electrical system fromdamage by short circuiting or overloading.
1. Refer to the fuse diagram to locate the fuse.
2. Pull out the fuse and examine it from the side to determine if the curved metal wire in the fuse is intact.
3. If the wire is broken, replace the fuse with a new fuse of the same color and amper-age.
WARNING
Never use a foreign object or a fuse with a higher amperage than that specified toreplace a fuse. This could cause significantdamage to the electrical system and possi-bly lead to a fire.
WARNING
Contact an authorized Volvo workshop for assistance replacing fuses not listed in theOwner's Manual. If fuse replacement isperformed incorrectly, significant damagecan be caused to the electrical system.
