{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 don’t 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 wouldn’t be covered
by your warranty.
Trying to start your vehicle by pushing or pulling it
won’t 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 system isn’t a 12-volt system
with a negative ground, both vehicles can be
damaged.
2. Get the vehicles close enough so the jumper cables
can reach, but be sure the vehicles aren’t touching
each other. If they are, it could cause a groundconnection you don’t want. You wouldn’t be able to
start your vehicle, and the bad grounding could
damage the electrical systems.
To avoid the possibility of the vehicles rolling, set
the parking brakefirmly on both vehicles involved in
the jump starting procedure. Put an automatic
transaxle in PARK (P) or a manual transaxle
in NEUTRAL before setting the parking brake.
Notice:If you leave your radio on, it could be badly
damaged. The repairs wouldn’t be covered by
your warranty.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter or in the accessory power outlet(s). Turn
off the radios and all lamps that aren’t needed. This
will avoid sparks and help save both batteries.
And it could save your radio!
4. Open the hoods and locate the batteries. Find the
positive (+) and negative (−) terminals on each
vehicle.
You will not need to access your battery for jump
starting. Your vehicle has a remote positive (+) jump
starting terminal for that purpose. The terminal is
located under a tethered cap at the front of the
underhood fuse and relay center. SeeEngine
Compartment Overview on page 5-10for more
information on location.

Headlamp Wiring
The headlamp wiring is protected by an internal circuit
breaker in thefloor console fuse block. An electrical
overload will cause the lamps to go on and off, or
in some cases to remain off. If this happens, have your
headlamp wiring checked right away.
Windshield Wiper Fuses
The windshield wiper motor is protected by an internal
circuit breaker and a fuse. If the motor overheats due to
heavy snow, etc., the wiper will stop until the motor
cools. If the overload is caused by some electrical
problem, be sure to get itfixed.
Power Windows and Other Power
Options
Circuit breakers in thefloor console fuse block protect
the power windows and other power accessories. When
the current load is too heavy, the circuit breaker
opens and closes, protecting the circuit until the problem
isfixed.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses, circuit breakers
and fusible thermal links.
Look at the silver-colored band inside the fuse. If the
band is broken or melted, replace the fuse. Be sure you
replace a bad fuse with a new one of the identical
size and rating.
If you ever have a problem on the road and don’t have
a spare fuse, you can borrow one that has the same
amperage or use one of the spare fuses in the
underhood fuse and relay center. Just pick some
feature of your vehicle that you can get along
without–like the radio or cigarette lighter - and use its
fuse, if it is the right amperage. Replace it as soon
as you can.
There are two fuse blocks in your vehicle: thefloor
console fuse block and the underhood fuse and relay
center.
