• Starting the engine when the battery is discharged
  The engine cannot be started by push-start-ing.
• 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.
• 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 certain 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.)
• When the battery is removed or dis- charged 
  • In some cases, it may not be possible to unlock the doors using the smart access system with push-button start when the battery is discharged. Use the wireless remote control or the mechanical key to lock or unlock the doors.
  • The engine may not start on the first attempt after the battery has recharged but will start normally after the second attempt. This is not a malfunction.
  • 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 discharged, be especially careful when reconnecting the battery.
  • Some systems may require initialization.

WARNING
Avoiding battery fires or explosions

• Make sure each jumper cable is connected to the correct terminal and that it is not unintentionally in contact with any other than the intended terminal.
• Do not allow the other end of the jumper cable connected to the “+” terminal to come into contact with any other parts or metal surfaces in the area, such as brackets or unpainted metal.
• Do not allow the + and – clamps of the jumper cables to come into contact with each other.
