MAINTENANCE AND SERVICE
Hybrid battery
The vehicle's electric motor is powered by a
rechargeable, maintenance-free, lithium-ion
hybrid battery.
NOTE
The vehicle cannot be started if the hybrid
battery is discharged.
NOTE
If both the starter battery and the hybrid bat-
tery are discharged, both batteries must be
charged. In such cases, it is not possible to
charge only the hybrid battery first.
The starter battery must have a certain level
of charge for it to be possible to charge the
hybrid battery.
WARNING
Hybrid battery replacement may only be per-
formed by a workshop – an authorized Volvo
workshop is recommended.
Coolant
The hybrid battery's cooling system has its own
expansion tank.

CAUTION
Filling the hybrid battery coolant should only
be performed by a workshop – an authorized
Volvo workshop is recommended.
