■

Starting the hybrid system when the 12-volt battery is discharged

The hybrid system cannot be started by push-starting.

■

To prevent 12-volt battery discharge

●

Turn off the headlights and the audio system while the hybrid system is off.

●

Turn off any unnecessary electrical components when the vehicle is running at a

low speed for an extended period, such as in heavy traffic.

■

Charging the 12-volt battery

The electricity stored in the 12-volt battery will discharge gradually even when the

vehicle is not in use, due to natural discharge and the draining effects of certain elec-

trical appliances. If the vehicle is left for a long time, the 12-volt battery may dis-

charge, and the hybrid system may be unable to start. (The 12-volt battery recharges

automatically while the hybrid system is operating.)

■

When recharging or replacing the 12-volt battery

●

Make sure the key is not inside the vehicle when recharging or replacing the 12-volt

battery to prevent the doors from being locked with the key left inside the vehicle

when the alarm operates.

●

In some cases, it may not be possible to unlock the doors using the smart access

system with push-button start when the 12-volt battery is discharged. Use the wire-

less remote control or the mechanical key to lock or unlock the doors.

●

The hybrid system may not start on the first attempt after the 12-volt battery has

recharged but will start normally after the second attempt. This is not a malfunction.

●

The “POWER” switch mode is memorized by the vehicle. When the 12-volt battery

is reconnected, the system will return to the mode it was in before the 12-volt bat-

tery was discharged. Before disconnecting the 12-volt battery, turn the “POWER”

switch off.

If you are unsure what mode the “POWER” switch was in before the 12-volt battery

discharged, be especially careful when reconnecting the 12-volt battery.
