STARTING AND STOPPING THE
ENGINE – PRECAUTIONS
WARNING: Extended idling at highengine speeds can produce very hightemperatures in the engine and exhaustsystem, creating the risk of fire or otherdamage.
WARNING: Do not park, idle or driveyour vehicle on dry grass or other dryground cover. The emission system heatsup the engine compartment and exhaustsystem, creating the risk of fire.
WARNING: Do not start the enginein a closed garage or in other enclosedareas. Exhaust fumes are toxic. Alwaysopen the garage door before you start theengine. Failure to follow this instructioncould result in personal injury or death.
WARNING: Do not use starting fluid,for example ether, in the air intake system.Such fluid could cause immediateexplosive damage to the engine andpossible personal injury.
WARNING: Exhaust leaks may resultin entry of harmful and potentially lethalfumes into the passenger compartment. Ifyou smell exhaust fumes inside yourvehicle, have your vehicle inspectedimmediately. Do not drive if you smellexhaust fumes.
The powertrain control system meets allCanadian interference-causing equipmentstandard requirements regulating theimpulse electrical field or radio noise.
Note:If you use your vehicle regularly abovethe altitude of 7,500 ft (2,286 m) and underthe temperature of -4.0°F (-20°C), it isrecommended to use the alternative engineoil. See Capacities and Specifications(page 467).
If you stop your vehicle and leave the engineidling for long periods, we recommend thatyou do one of the following:
•Open the windows at least 1 in (2.5 cm).
•Set your climate control to outside air.

1.Fully press the brake pedal.
Note:Do not touch the accelerator pedal.
2.Press the push button ignition switch.
Note:The engine may continue cranking forup to 15 seconds or until it starts.
Note:The engine takes longer to start atlower temperatures. It may crank for severalseconds when very cold.
RESTARTING THE ENGINE AFTERSTOPPING IT
The system allows you to start the enginewithin 10 seconds of switching it off, even ifit does not detect a valid passive key.
Within 10 seconds of switching the engineoff, fully press the brake pedal and press thepush button ignition switch. After 10 seconds,you can no longer start the engine if thesystem does not detect a valid passive key.

ENGINE BLOCK HEATER (IF EQUIPPED)
ENGINE BLOCK HEATERPRECAUTIONS
WARNING: Failure to follow engineblock heater instructions could result inproperty damage or serious personalinjury.
WARNING: Do not use your heaterwith ungrounded electrical systems ortwo-pronged adapters. There is a risk ofelectrical shock.
WARNING: Do not fully close thehood, or allow it to drop under its ownweight when using the engine blockheater. This could damage the power cableand may cause an electrical short resultingin fire, injury and property damage.
We recommend that you do the following fora safe and correct operation:
•Use a 16-gauge outdoor extension cordthat is product certified by Underwriter’sLaboratory (UL) or Canadian StandardsAssociation (CSA). This extension cordmust be suitable for use outdoors, in coldtemperatures, and be clearly markedSuitable for Use with OutdoorAppliances. Do not use an indoorextension cord outdoors. This couldresult in an electric shock or become afire hazard.
•Use as short an extension cord aspossible.
•Do not use multiple extension cords.
•Make sure that when in operation, theextension cord plug and engine blockheater cord plug connections are freeand clear of water. This could cause anelectric shock or fire.
•If the engine block heater cord is underthe hood, do not remove the wiring fromits original location. Do not close thehood on the extension wiring.
•Park your vehicle in a clean area, clearof combustible materials.
•Firmly connect the engine block heatercord and the extension cord.
•Check the extension cord for heatanywhere when the system has beenoperating for approximately 30 minutes.
•Unplug and properly stow the systembefore starting and driving your vehicle.The protective cover seals the terminalsof the engine block heater cord plugwhen not in use.
•Check the engine block heater systemfor proper operation before winter.
HOW DOES THE ENGINE BLOCKHEATER WORK
The engine block heater warms the enginecoolant. This allows the climate controlsystem to quickly respond. The equipmentincludes a heater element installed in theengine block and a wire harness. You canconnect the system to a grounded 220-240volt AC electrical source.
203
2023 Navigator (TB9) Canada/United States of America, enUSA, Edition date: 202207, DOMStarting and Stopping the Engine

Note:The engine block heater is mosteffective when outdoor temperatures arebelow 0°F (-18°C).
USING THE ENGINE BLOCK HEATER
Make sure the receptacle terminals are cleanand dry prior to use. Clean them with a drycloth if necessary.
The heater uses 0.4 to 1.0 kilowatt-hours ofenergy per hour of use. The system does nothave a thermostat. It achieves maximumtemperature after approximately three hoursof operation. Using the engine block heaterlonger than three hours does not improvesystem performance and unnecessarily useselectricity.
