COLD WEATHER STARTING
Perform the following to assure efficient starting in cold weather:
• Use the proper grade oil for your climate. Refer to your engine
operator's manual for proper grade oil.
• Test the battery more frequently to assure ample power for starting.
• All electrical connections should be tight and in good condition to
prevent losses through loose or corroded connections.
USING THE ENGINE BLOCK HEATER (IF EQUIPPED)
An engine block heater warms the engine coolant, which improves
starting, warms up the engine faster and allows the heater-defroster
system to respond quickly. Use of an engine block heater is strongly
recommended if you live in a region where temperatures reach -23°C
(-10°F) or below.
For best results, plug the heater in at least three hours before starting
the vehicle. Using the heater for longer than three hours will not harm
the engine, so the heater can be plugged in the night before starting the
vehicle.
To prevent electrical shock, do not use your heater with
ungrounded electrical systems or two-pronged (cheater) adapters.
ENGINE SHUTDOWN SYSTEM (IF EQUIPPED)
This system is designed to help prevent engine damage that could result
from operating the engine during a prolonged period of low engine oil
pressure, high engine coolant temperature or low coolant level. If any of
these conditions occur, a warning light will illuminate and a chime will
sound warning the operator that the engine will shutdown in 30 seconds.
This is to allow time for the operator to move the vehicle off the road. If
additional time is required, the engine can be restarted and run each
time for approximately 30 seconds.
Do not attempt to use this restarting feature to drive the vehicle, serious
engine damage could result.
