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.
