The battery is located in front of the rear
seat bench and below the cup holder.
Jump starting terminals are located on the
driver’s side of the engine compartment
(
page 398).
The battery should always be sufficiently
charged in order to achieve its rated
service life. Refer to Maintenance Booklet
for battery maintenance intervals.
If you use your vehicle mostly for
short-distance trips, you will need to have
the battery charge checked more
frequently.
