562 5-2. Steps to take in an emergency
■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 turned
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, etc.
■ When the battery is removed or discharged
●The power back door must be initialized ( P. 6 4 )
● The tire inflation pressure warning system must be initialized. ( P. 480)
■ 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.)
Vehicles without smart key system:
Maintain the engine speed of the second vehicle, and turn
the engine switch to the “ON” position, then start the vehi-
cle's engine.
Vehicles with smart key system:
Maintain the engine speed of the second vehicle, and turn
the “ENGINE START STOP” switch to IGNITION ON mode,
then start the vehicle's engine.

cables in the exact reverse order in which they were con-
nected.

dealer as soon as possible.STEP4
