Vehicle Storage
If you are not going to drive your vehicle for 25 days
or more, remove the black, negative (
−
) cable from
the battery. This will help keep your battery from
running down.
{ 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 5-43 for tips on working around a battery
without getting hurt.
Also, for your audio system, see Theft-Deterrent
Feature on page 3-132.
Jump Starting
If your 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.
Notice: Ignoring these steps could result in costly
damage to your vehicle that would not be covered
by your warranty.
Trying to start your vehicle by pushing or pulling it
will not work, and it could damage your vehicle.
1. Check the other vehicle. It must have a 12-volt
battery with a negative ground system.
Notice: If the other vehicle’s system is not a 12-volt
system with a negative ground, both vehicles can
be damaged. Only use vehicles with 12-volt systems
with negative grounds to jump start your vehicle.
