■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 running
at a low speed for an extended period, such as in heavy traffic.
■ When recharging or replacing the battery
●Vehicles with a smart key system: In some cases, it may not be possible to
unlock the doors using the smart key system when the battery is dis-
charged. Use the wireless remote control or the mechanical key to lock or
unlock the doors.
● Vehicles with a smart key system: The engine may not start on the first
attempt after the battery has recharged but will start normally after the sec-
ond attempt. This is not a malfunction.
● Vehicles with a smart key system: The engine switch mode is memorized by
the vehicle. When the battery is reconnected, the system will return to the
mode it was in before the battery was discharged. Before disconnecting the
battery, turn the engine switch off.
If you are unsure what mode the engine switch was in before the battery dis-
charged, be especially careful when reconnecting the battery.
● Vehicle with power back door: The power back door must be initialized.
(P. 672)
■ 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.)
