Battery
Your vehicle has a maintenance free battery. When it is
time for a new battery, see your dealer/retailer for
one that has the replacement number shown on the
original battery’s label.
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.
The battery is located under the rear seat cushion.
To access the battery, see “Removing the Rear Seat
Cushion” underRear Underseat Fuse Block on
page 5-108. You do not need to access the battery to
jump start your vehicle. SeeJump Starting on
page 5-48.{CAUTION:
A battery that is not properly vented can let
sulfuric acid fumes into the area under the rear
seat cushion. These fumes can damage your
rear seat safety belt systems. You may not be
able to see this damage, and the safety belts
might not provide the protection needed in a
crash. If a replacement battery is ever needed,
it must be vented in the same manner as the
original battery. Always make sure that the
vent hose is properly reattached before
reinstalling the seat cushion.
