Starting the Engine
The pre-heating time is adjusted to suit the engine
temperature, and can last for up to 50 seconds both
before and after starting.
The starter motor connection time is maximized to 20
seconds. After that, the starter motor circuit is
temporarily cut to protect the starter motor against
overheating.

Starting in Extreme Cold
Certain preparations must be made to enable engine
starting in extreme cold, and in some cases to make
starting possible at all:
•
Use a fuel that is approved for the prevailing
temperature. This reduces the risk of paraffin wax
precipitation in the fuel system.
•
Use a synthetic engine oil of a viscosity
recommended for the prevailing temperature to
achieve satisfactory lubrication. Refer to
Viscosity, page 83. Synthetic lubricants are able
to handle a wider temperature range than mineral-
based lubricants.
•
Pre-heat the coolant with a separately installed
electric engine heater. In extreme cases, a diesel-
fired engine heater may be necessary. Ask your
Volvo Penta dealer for advice.
•
Make sure the cooling system is filled with a glycol
mixture. Refer to Maintenance, page 65.
•
The batteries must be in good condition. Cold
weather reduces battery capacity. Increased battery
capacity may be necessary.
