- Summary
- SERVICE INFORMATION For QX60 Hybrid Vehicles, go to page 4. Q50, Q70, and M35 Hybrid Vehicles The internal combustion (IC) engine in the Q50, Q70, and M35 Hybrid vehicles is started using a high voltage motor that is integrated into the transmission. The high voltage motor gets its power from the high voltage Lithium-Ion (Li-ion) battery that is mounted between the trunk room and the rear seat. The Li-ion battery cannot be recharged using an external battery charger; therefore it is very important that the battery state of charge (SOC) is properly maintained during extended storage periods. Action must to be taken in order to prevent excessive discharge of the high voltage Li-ion battery during an extended storage period. If the reserve capacity of the Li-ion battery is not sufficient, the hybrid system cannot be started. Perform the Battery Discharge Prevention During Extended Storage procedure in this bulletin once a month (every 30 days). NOTE: A discharged high voltage Li-ion battery is not a warrantable issue. See this bulletin for further detail.
