 - 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, etc.

 - 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.)

CAUTION

 - Avoiding battery fires or explosions

Observe the following precautions to prevent accidentally igniting the flammable gas that may be emitted from the battery:

• Make sure the jumper cable is connected to the correct terminal and that it is not unintentionally in contact with any part other than the intended terminal.

• Do not allow the + and - clamps of the jumper cables to come into contact with each other.

• Do not smoke, use matches, cigarette lighters or allow open flame near the bat- tery.

 - Battery precautions

The battery contains poisonous and corrosive acidic electrolyte, while related parts contain lead and lead compounds. Observe the following precautions when han- dling the battery:

• When working with the battery, always wear safety glasses and take care not to allow any battery fluids (acid) to come into contact with skin, clothing or the vehi- cle body.

• Do not lean over the battery.

• If the battery fluid comes into contact with the skin or eyes, immediately wash the affected area with water and seek medical attention.

Place a wet sponge or cloth over the affected area until medical attention can be received.

• Always wash your hands after handling the battery support, terminals, and other battery-related parts.

• Do not allow children near the battery.

NOTICE

 - When handling jumper cables

When connecting the jumper cables, ensure that they do not become entangled in the cooling fans or belt.
