Never attempt to place the vehicle
in motion, or run the engine with
batteries disconnected
Keep the battery clean and dry
Look for any signs of damage
Battery terminals should not be
coated with improper grease. Use
a commercially available,
noncorrosive, non-conductive
terminal coating, or petroleum jelly.
Never use a fast charger as a
booster to start the engine. This
can seriously damage sensitive
electronic components such as
relays, radio, etc., as well as the
battery charger. Fast charging a
battery is dangerous and should
only be attempted by a competent
mechanic with the proper
equipment.

In Cab Battery Access
Your vehicle may be equipped with
Absorbed Glass Mat (AGM) batteries

allows batteries to be positioned in any
orientation without risk of leaking.

passenger side seat base to the
battery box assembly.
3. Remove the seat and seat base as

batteries.
