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 on page 5-44 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.
Also, for your audio system, see Theft-Deterrent Feature
on page 3-109.
Jump Starting
If the vehicle’s battery has run down, you may want to
use another vehicle and some jumper cables to start
your vehicle. Be sure to use the following steps to do
it safely.
{ CAUTION:
Batteries can hurt you. They can be dangerous
because:
• They contain acid that can burn you.
• They contain gas that can explode or ignite.
• They contain enough electricity to burn you.
If you do not follow these steps exactly, some or
all of these things can hurt you.
