Infiniti QX: Engine block heater (if so equipped)
Engine block heaters are used to assist in cold temperature starting. The engine block heater should be used when the outside temperature is 208F (−78C) or lower.
To use the engine block heater
1. Turn the engine off. 2. Open the hood and unwrap the engine block heater cord. 3. Plug the engine block heater cord into a grounded 3-wire, 3-pronged extension cord. 4. Plug the extension cord into a Ground Fault Interrupt (GFI) protected, grounded 110-volt AC (VAC) outlet. 5. The engine block heater must be plugged in for at least 2 - 4 hours, depending on outside temperatures, to properly warm the engine coolant. Use an appropriate timer to turn the engine block heater on. 6. Before starting the engine, unplug and properly store the cord to keep it away from moving parts.
WARNING
► Do not use your engine block heater with
an ungrounded electrical system or a 2-
pronged adapter. You can be seriously
injured by an electrical shock if you use
an ungrounded connection.

block heater cord before starting
the engine. Damage to the cord could
result in an electrical shock and can
cause serious injury.
► Use a heavy-duty 3-wire, 3-pronged

Plug the extension cord into a Ground
Fault Interrupt (GFI) protected, grounded
110-VAC outlet. Failure to use the proper
extension cord or a grounded outlet can
result in a fire or electrical shock and
cause serious personal injury.
