ENGINE BLOCK/TRANSMISSION HEATER — IF
EQUIPPED
To ensure reliable starting/operating at these tempera-
tures, use of an externally powered electric engine block/
transmission heater (available from your authorized
dealer) is recommended.
The engine block heater warms engine coolant and
permits quicker starts in cold weather. The transmission
heaters warm gearbox oil and hydraulic actuation system
oil to operate in cold weather. Connect the heater cord to
a ground-fault interrupter protected 110–115 Volt AC
electrical outlet with a grounded, three-wire extension
cord.
Its use is recommended for environments that routinely
fall below -10°F (-23°C). It should be used when the
vehicle has not been running overnight or longer periods
and should be plugged in two hours prior to start. Its use
is required for cold starts with temperatures under -17°F
(-27°C).
In the case of LOW temperature after Starting, the
Automated Manual Transmission may not be able to
engage first gear. In this case a message
⬙
Shift not
allowed
⬙
appears. In this situation use the engine block
heater.
WARNING!
Remember to disconnect the cord before driving.
Damage to the 110–115 Volt electrical cord could
cause electrocution.
NOTE: The block heater will require 110 Volts AC and
6.5 Amps to activate the heater element.
