Connect a positive jumper cable clamp to the positive (+) battery terminal on
your vehicle.
Connect the clamp on the other end of the positive cable to the positive (+)
battery terminal on the second vehicle.
Connect a negative cable clamp to the negative (-) battery terminal on the
second vehicle.
Connect the clamp at the other end of the negative cable to a solid, stationary,
unpainted metallic point away from the battery and any moving parts, as
shown in the illustration.
Start the engine of the second vehicle. Increase the engine speed slightly and

as possible.
■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 stopped. (Vehicles with a Stop & Start system: except when the engine is stopped by the Stop &
Start system.)
●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 beunable to start. (The battery recharges automatically during driving.)
