Warning: Battery posts, terminals, and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and reproductive harm. Wash hands after handling.

Vehicle Storage

Caution: Batteries have acid that can burn you and gas that can explode. You can be badly hurt if you are not careful. See Jump Starting for tips on working around a battery without getting hurt.

Infrequent Usage: If the vehicle is driven infrequently, remove the black, negative (-) cable from the battery. This helps keep the battery from running down.

Extended Storage: For extended storage of the vehicle, remove the black, negative (-) cable from the battery or use a battery trickle charger. This helps maintain the charge of the battery over an extended period of time.

If a new 36-volt hybrid battery system is needed, see your dealer/retailer.

Vehicle Storage

Infrequent Usage: If the vehicle is driven infrequently, remove the 12-volt battery black, negative (-) cable, the one that is exposed. This helps keep the battery from running down.

Extended Storage: For extended storage of the vehicle, remove the 12-volt battery black, negative (-) cable from the battery or use a battery trickle charger. This helps maintain the charge of the battery over an extended period of time.

Remember to reconnect the battery when ready to drive the vehicle.

Notice: The 36-volt hybrid battery system should be serviced only by a qualified facility to avoid battery system damage. See your dealer/retailer if service is needed.

Notice: If the vehicle is not driven for over two months, the 36-volt hybrid battery can be permanently damaged.

The 36-volt battery is located behind the rear seat, in the trunk. If the vehicle is stored for an extended period of time, drive the vehicle every two months for about half an hour to keep the 36-volt hybrid battery charged and in good working condition.
