WARNING: Batteries normally produce explosive gases which can cause personal injury. Therefore, do not allow flames, sparks or lighted substances to come near the battery. When charging or working near a battery, always shield your face and protect your eyes. Always provide ventilation.

WARNING: Keep body from under the auxiliary or secondary battery when disconnecting or reconnecting the auxiliary or secondary battery safety straps since the battery weighs 50 pounds and bodily injury can result.

CAUTION: Failure to accurately follow the battery disconnect procedures outlined in this section will result in vehicle or component damage.

NOTE: The preferred method of service requires the use of a floor hoist to lift the vehicle overhead, and a transmission jack to support and lower the auxiliary or secondary battery case.

NOTE: The auxiliary or secondary battery can be charged while the auxiliary or secondary battery safety straps are connected to the vehicle. Follow the procedures up to and including disconnection of the auxiliary or secondary battery cables.

Disable the vehicle electrical supply; refer to DUAL BATTERY DISCONNECT - GASOLINE or DUAL BATTERY DISCONNECT - DIESEL in General Procedures.
