iQ EV
ADDITIONAL INFORMATION
Introduction
The iQ EV is equipped with 2 types of batteries:
• Electric Vehicle (EV) Traction Battery
• 12-volt Auxiliary Battery
If the iQ EV is put into storage, the state of charge (SOC) of the EV battery and auxiliary battery
will gradually decrease. To prevent the auxiliary battery from becoming discharged during storage,
proper maintenance is necessary.
Please perform the following maintenance service for the EV battery and 12-volt auxiliary battery.
NOTE
• Before disconnecting the auxiliary battery, confirm the shift lever is in the “P” position and
apply the parking brake completely. The shift lever CANNOT be shifted from the “P” position
with the 12-volt auxiliary battery disconnected.
• When the negative (–) terminal of the auxiliary battery is reconnected, the EV system may not
operate if the vehicle is already in “Ready On” state. If this occurs, push the Start/Stop switch
to re-initiate the “Ready On” mode. The “Ready” light should illuminate on the Instrument
Panel. If the EV system will not “Ready On”, refer to the Repair Manual for diagnosis.
