Battery
This 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, seeRear Underseat Fuse Block
on page 5-98. Access to the battery is not necessary to
jump start the vehicle. SeeJump Starting on page 5-38.{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 the rear
seat safety belt systems. You might 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.
