■
Starting the engine when the battery is discharged
The engine cannot be started by push-starting.
■ To prevent battery discharge
●Turn off the headlights and the audio system while the engine is off.
● Turn off any unnecessary electrical components when the vehicle is run-
ning at a low speed for an extended period, such as in heavy traffic.
■ When the battery is removed or discharged
●The power sliding door (if equipped) must be initialized. ( P. 74)
● The power back door (if equipped) must be initialized. ( P. 87)
● Make sure that the key is not inside the vehicle when recharging or
replacing the battery. The key may be locked in the vehicle if the alarm is
activated. ( P. 165)
■ Charging the battery
The electricity stored in the battery will discharge gradually even when the
vehicle is not in use, due to natural discharge and the draining effects of cer-
tain electrical appliances. If the vehicle is left for a long time, the battery may
discharge, and the engine may be unable to start. (The battery recharges
automatically during driving.)
