Jump Starting
WARNING
Batteries can emit explosive gases. To avoid personal
injury, always ventilate the compartment before
servicing the batteries. To avoid arcing, remove the
negative (-) battery cable first and attach the
negative(-) battery cable last.
CAUTION
When using jumper cables to start the engine, make
sure to connect the cables in parallel: Positive (+) to
positive (+) and negative(-) to negative (-). When using
an external electrical source to start the engine, turn
the disconnect switch to the OFF position. Remove
the key before attaching the jumper cables.
CAUTION
To avoid damage to engine parts, do not connect
jumper starting or battery charging cable to any fuel
system or electronic component.
This illustration shows a typical parallel battery
connection. This arrangement doubles the cranking
amperage.
NOTE: Always reference the relevant OEM literature for
jump starting procedures. Failure to follow correct
procedures can result in damage to the ECM and other
electrical equipment.
This illustration shows a typical series battery connection.
This arrangement, positive (+) to negative (-), doubles the
voltage.
NOTE: Always reference the relevant OEM literature for
jump starting procedures. Failure to follow correct
procedures can result in damage to the ECM and other
electrical equipment.
Cold Weather Starting
General Information
CAUTION
To reduce the possibility of damage to the lubricating
oil pan, due to the composite materials used in the
manufacture of the lubricating oil pan, under no
circumstances should an external heat source be
applied directly or indirectly to the lubricating oil pan.
Follow the Normal Starting Procedure in this section. If
equipped with an intake air heater, the Wait-To-Start lamp
will stay on longer.
Refer to the OEM service manual for any additional cold
weather starting procedures.
