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 408).
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.

Note:The engine block heater is mosteffective when outdoor temperatures arebelow 0°F (-18°C). We recommend the useof engine block heater to improve enginecold start performance.
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.
STOPPING THE ENGINE
STOPPING THE ENGINE WHEN YOURVEHICLE IS STATIONARY
1.Shift into park (P).
2.Apply the parking brake.
3.Wait until the engine reaches idle speed.
4.Press the push button ignition switch.
STOPPING THE ENGINE WHEN YOURVEHICLE IS MOVING
WARNING: Switching off the enginewhen your vehicle is still moving results ina significant decrease in brakingassistance. Higher effort is required toapply the brakes and to stop your vehicle.A significant decrease in steeringassistance could also occur. The steeringdoes not lock, but higher effort could be
required to steer your vehicle. When youswitch the ignition off, some electricalcircuits, for example airbags, also turn off.If you unintentionally switch the ignitionoff, shift into neutral (N) and restart theengine.
1.Press and hold the push button ignitionswitch until the engine stops, or press itthree times within two seconds.
2.Shift into neutral and use the brakes tobring your vehicle to a safe stop.

WHAT IS THE CATALYTIC
CONVERTER
The catalytic converter is part of yourvehicle's emissions system and filters harmfulpollutants from the exhaust gas.
CATALYTIC CONVERTER
PRECAUTIONS
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: The normal operatingtemperature of the exhaust system is veryhigh. Never work around or attempt torepair any part of the exhaust system untilit has cooled. Use special care whenworking around the catalytic converter.The catalytic converter heats up to a veryhigh temperature after only a short periodof engine operation and stays hot after theengine is switched off.
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.
To avoid damaging the catalytic converter:
•Do not crank the engine for more than10 seconds at a time.
•Do not run the engine with a spark pluglead disconnected.
•Do not push-start or tow-start yourvehicle. Use booster cables. See JumpStarting Precautions (page 318).
•Use the correct fuel. See Fuel andRefueling (page 203).
•Do not switch the ignition off when yourvehicle is moving.
•Avoid running out of fuel.
•Have the items listed in scheduledmaintenance information performedaccording to the specified schedule.
Note:Do not make any unauthorizedchanges to your vehicle or engine. By law,vehicle owners and anyone whomanufactures, repairs, or services a fleet ofvehicles are not permitted to intentionallyremove an emission control device orprevent it from working.

Note:The pre-collision assist systemdisables when you select four-wheel drivelow or manually disable AdvanceTrac™.
Note:Brake support and automaticemergency braking are active at speeds upto 75 mph (120 km/h). If the vehicle has aradar sensor included with adaptive cruisecontrol, then brake support and automaticemergency braking are active up to themaximum speed of the vehicle.
Pedestrian Detection Limitations
Pedestrian detection is active at speeds upto 50 mph (80 km/h).
Pedestrian detection functions optimallywhen detected hazards are clearlyidentifiable. System performance may reducein situations where pedestrians are running,partly obscured, have a complexbackground, or cannot be distinguished froma group.
LOCATING THE PRE-COLLISION
ASSIST SENSORS
Camera.1
Radar sensor (if equipped).2
If a message regarding a blocked sensor orcamera appears in the information display,something is obstructing the radar signals orcamera images. The radar sensor is behindthe fascia cover in the center of the lowergrille. With a blocked sensor or camera, thesystem may not function, or performancemay reduce. See Pre-Collision Assist –Information Messages (page 292).
Note:Proper system operation requires aclear view of the road by the camera. Haveany windshield damage in the area of thecamera's field of view repaired.
Note:If something hits the front end of yourvehicle or damage occurs and your vehiclehas a radar sensor, the radar sensing zonecould change. This could cause missed orfalse vehicle detections. Have your vehicleserviced to have the radar checked forproper coverage and operation.
Note:If your vehicle detects excessive heatat the camera or a potential misalignmentcondition, a message could display in theinformation display indicating temporarysensor unavailability. When operationalconditions are correct, the messagedeactivates. For example, when the ambienttemperature around the sensor decreasesor the sensor recalibrates successfully.

COLD WEATHER PRECAUTIONS
The functional operation of somecomponents and systems can be affected attemperatures below approximately -13°F(-25°C).
BREAKING-IN
You need to break in new tires forapproximately 300 mi (480 km). During thistime, your vehicle may exhibit some unusualdriving characteristics.
DRIVING ECONOMICALLY
The following helps to improve fuelconsumption:
•Drive smoothly, accelerate gently andanticipate the road ahead to avoid heavybraking.
•Regularly check your tire pressures andmake sure that they are inflated to thecorrect pressure.
•Follow the recommended maintenanceschedule and carry out therecommended checks.
•Plan your journey and check the trafficbefore you set off. It is more efficient tocombine errands into a single tripwhenever possible.
•Avoid idling the engine in cold weatheror for extended periods. Start the engineonly when you are ready to set off.
•Do not carry unnecessary weight in yourvehicle as extra weight wastes fuel.
•Do not add unnecessary accessories tothe exterior of your vehicle, for examplerunning boards. If you use a roof rack,remember to fold it down or remove itwhen not in use.
•Do not shift into neutral when you arebraking or when your vehicle is slowingdown.
•Shut all windows when driving at highspeeds.
•Switch off all electric systems when notin use, for example air conditioning. Makesure that you unplug any accessoriesfrom the auxiliary power points when notin use.
DRIVING IN SPECIAL CONDITIONS
DRIVING THROUGH MUD AND WATER
Mud
Be cautious of sudden changes in vehiclespeed or direction when you are driving inmud. Even all-wheel drive and four-wheeldrive vehicles can lose traction in mud. Ifyour vehicle slides, steer in the direction ofthe slide until you regain control of yourvehicle. After driving through mud, clean offresidue stuck to rotating driveshafts and tires.Excess residue can cause an imbalance thatcould damage drive components.

Severe Climates
If you drive in extremely cold climates, youmay need to increase the coolantconcentration above 50%.
Note:A coolant concentration of 60%provides improved freeze point protection.Coolant concentrations above 60% decreasethe overheat protection characteristics ofthe coolant and could cause enginedamage.
If you drive in extremely hot climates, youmay need to decrease the coolantconcentration to 40%.
Note:A coolant concentration of 40%provides improved overheat protection.Coolant concentrations below 40% decreasethe overheat and corrosion protectioncharacteristics of the coolant and couldcause engine damage.
Coolant Change
WARNING: Do not dispose of coolantin the household refuse or the publicsewage system. Use an authorized wastedisposal facility.
Change the coolant at specific mileageintervals. Refer to the scheduledmaintenance information. See NormalScheduled Maintenance (page 474).
Note:Dispose of used coolant in theappropriate manner.
Follow your community's regulations andstandards for recycling and disposing ofautomotive fluids.
Fail-Safe Cooling
Fail-safe cooling allows you to temporarilydrive your vehicle before any incrementalcomponent damage occurs. The fail-safedistance depends on ambient temperature,vehicle load and terrain.
How Fail-Safe Cooling Works
WARNING: If you continue to driveyour vehicle when the engine isoverheating, the engine could stop withoutwarning. Failure to follow this instructioncould result in the loss of control of yourvehicle.
If the engine begins to overheat,the coolant temperature gaugemoves toward the red zone:
A warning lamp illuminates and amessage may appear in theinformation display.
If the engine reaches a presetover-temperature condition, the engineautomatically switches to alternating cylinderoperation. Each disabled cylinder acts as anair pump and cools the engine.
When this occurs, your vehicle still operates,however:
•Engine power is limited.
•The air conditioning system turns off.
351
2023 Nautilus (CD9) Canada/United States of America, enUSA, Edition date: 202207, DOMMaintenanceE103308 E67028

Continued operation increases the enginetemperature, causing the engine tocompletely shut down. Your steering andbraking effort increases in this situation.
When the engine temperature cools, you canre-start the engine. Have your vehiclechecked as soon as possible to minimizeengine damage.
When Fail-Safe Mode Is Activated
WARNING: Fail-safe mode is for useduring emergencies only. Operate yourvehicle in fail-safe mode only as long asnecessary to bring your vehicle to rest ina safe location and seek immediate repairs.When in fail-safe mode, your vehicle willhave limited power, will not be able tomaintain high-speed operation, and maycompletely shut down without warning,potentially losing engine power, powersteering assist, and power brake assist,which may increase the possibility of acrash resulting in serious injury.
WARNING: Do not remove thecoolant reservoir cap when the engine ison or the cooling system is hot. Wait 10minutes for the cooling system to cooldown. Cover the coolant reservoir cap witha thick cloth to prevent the possibility ofscalding and slowly remove the cap.Failure to follow this instruction could resultin personal injury.
Your vehicle has limited engine power whenin the fail-safe mode, drive your vehicle withcaution. Your vehicle does not maintainhigh-speed operation and the engine couldoperate poorly.
Remember that the engine is capable ofautomatically shutting down to preventengine damage. In this situation:
1.Pull off the road as soon as safelypossible and switch the engine off.
2.If you are a member of a roadsideassistance program, we recommend thatyou contact your roadside assistanceservice provider.
3.If this is not possible, wait for a shortperiod of time for the engine to cool.
4.Check the coolant level. If the coolantlevel is at or below the minimum mark,add prediluted coolant immediately.
5.When the engine temperature cools, youcan re-start the engine. Have your vehiclechecked as soon as possible to minimizeengine damage.
Note:If you continue to drive your vehicle infail-safe mode without repairing it, you willdamage your engine.
Engine Coolant TemperatureManagement (If Equipped)
WARNING: To reduce the risk ofcrash and injury, be prepared that thevehicle speed may reduce and the vehiclemay not be able to accelerate with fullpower until the coolant temperaturereduces.

If you tow a trailer with your vehicle, theengine may temporarily reach a highertemperature during severe operatingconditions, for example ascending a long orsteep grade in high ambient temperatures.
At this time, you may notice the coolanttemperature gauge moves toward the redzone and a message may appear in theinformation display.
You may notice a reduction in vehicle speedcaused by reduced engine power in orderto manage the engine coolant temperature. Your vehicle may enter this mode if certainhigh-temperature and high-load conditionstake place. The amount of speed reductiondepends on vehicle loading, grade andambient temperature. If this occurs, there isno need to stop your vehicle. You cancontinue to drive.
The air conditioning may automatically turnon and off during severe operatingconditions to protect the engine fromoverheating. When the coolant temperaturedecreases to the normal operatingtemperature, the air conditioning turns on.
If the coolant temperature gauge moves fullyinto the red zone, or if the coolanttemperature warning or service engine soonmessages appear in your information display,do the following:
1.Stop your vehicle as soon as it is safe todo so. Fully apply the parking brake, shiftinto park (P) or neutral (N).
2.Leave the engine running until thecoolant temperature gauge needlereturns to the normal position. If thetemperature does not drop after severalminutes, follow the remaining steps.
3.Switch the engine off and wait for it tocool. Check the coolant level.
4.If the coolant level is at or below theminimum mark, add prediluted coolantimmediately.
5.If the coolant level is normal, restart theengine and continue.
ENGINE AIR FILTER
CHANGING THE ENGINE AIR FILTER -2.0L
WARNING: To reduce the risk ofvehicle damage and personal burn injuries,do not start your engine with the aircleaner removed and do not remove itwhile the engine is running.
Change the air filter element at the properintervals.
When changing the air filter element, useonly the air filter element listed. SeeCapacities and Specifications (page 408).
Note:Failure to use the correct air filterelement could result in severe enginedamage that the vehicle warranty may notcover.
