CLIMATE CONTROL HINTS
General Hints
•Prolonged use of recirculated air maycause the windows to fog up.
•You may feel a small amount of air fromthe footwell air vents regardless of theair distribution setting.
•To reduce humidity build-up inside yourvehicle, do not drive with the systemswitched off or with recirculated airalways switched on.
•Do not place objects under the frontseats as this may interfere with theairflow to the rear seats.
•Remove any snow, ice or leaves from theair intake area at the base of thewindshield.
•To improve the time to reach acomfortable temperature in hot weather,drive with the windows open until youfeel cold air through the air vents.
Automatic Climate Control
•Adjusting the settings when your vehicleinterior is extremely hot or cold is notnecessary. Automatic mode is bestrecommended to maintain settemperature.
•The system adjusts to heat or cool theinterior to the temperature you select asquickly as possible.
•For the system to function efficiently, theinstrument panel and side air ventsshould be fully open.
•If you press AUTO during cold outsidetemperatures, the system directs air flowto the windshield and side window airvents.In addition, the blower motor mayrun at a slower speed until the enginewarms up.
•If you press AUTO during hottemperatures and the inside of thevehicle is hot, the system usesrecirculated air to maximize interiorcooling. Blower motor speed may alsoreduce until the air cools.

Your vehicle may have a temporary orconventional spare tire. A temporary sparetire is different in diameter or width,tread-type, or is from a different manufacturerthan the road tires on your vehicle. Consultinformation on the tire label or SafetyCompliance label for limitations when using.
When towing a trailer:
•Obey country specific regulations fortowing a trailer.
•Do not drive faster than 70 mph(113 km/h) during the first 500 mi(800 km).
•Do not make full-throttle starts.
•Check your hitch, electrical connectionsand trailer wheel lug nuts thoroughly afteryou have traveled 50 mi (80 km).
•When stopped in congested or heavytraffic during hot weather, place thetransmission in park (P) to aid engine andtransmission cooling and to help A/Cperformance.
•Turn off the speed control with heavyloads or in hilly terrain. The speed controlmay turn off when you are towing onlong, steep slopes.
•Shift to a lower gear when driving downa long or steep hill. Do not continuouslyapply the brakes, as they may overheatand become less effective.
•If your transmission has Grade Assist orTow/Haul, use this feature when towing.This provides engine braking and helpseliminate excessive transmission shiftingfor optimum fuel economy andtransmission cooling.
•Your vehicle has AdvanceTrac with rollstability control. When towing a trailer,additional loads could cause theAdvanceTrac system to engage duringcornering maneuvers. Reduce corneringspeeds to make sure that you canmaintain control of the vehicle and trailerif the AdvanceTrac system engages.
•Allow more distance for stopping with atrailer attached. Anticipate stops andgradually brake.
•Avoid parking on a slope. However, ifyou must park on a slope, turn thesteering wheel to point your vehicle tiresaway from traffic flow, set the parkingbrake, place the transmission in park (P)and place wheel chocks in front and backof the trailer wheels.
Note:Chocks are not included with yourvehicle.

ENGINE OIL CAPACITY ANDSPECIFICATION
For filling information, please refer to theCapacities and Specifications section of yourowner's manual. See Engine Oil Capacityand Specification (page 414).
CHECKING THE COOLANT
When the engine is cold, check theconcentration and level of the coolant at theintervals listed in the scheduled maintenanceinformation. See Scheduled Maintenance(page 470).
Note:Make sure that the coolant level isbetween the minimum and maximum markson the coolant reservoir.
Note: Coolant expands when it is hot. Thelevel may extend beyond the MAX mark.
If the coolant level is at or below theminimum mark, add prediluted coolantimmediately.
Maintain coolant concentration within 48%to 50%, which equates to a freeze pointbetween -29°F (-34°C) and -35°F (-37°C).Coolant concentration should be checkedusing a refractometer. We do not recommendthe use of hydrometers or coolant test stripsfor measuring coolant concentration.
Adding Coolant
WARNING: Keep your hands andclothing clear of the cooling fan.
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.
WARNING: Do not add coolant whenthe vehicle is on or the cooling system ishot. Failure to follow this instruction couldresult in personal injury.
WARNING: Do not add coolantfurther than the MAX mark.
WARNING: Do not put coolant in thewindshield washer reservoir. If sprayed onthe windshield, coolant could make itdifficult to see through the windshield.

2023 Nautilus (CD9) Canada/United States of America, enUSA, Edition date: 202207, DOMMaintenance

WARNING: Do not allow the fluid totouch your skin or eyes. If this happens,rinse the affected areas immediately withplenty of water and contact your physician.
Note: Do not use stop leak pellets, coolingsystem sealants, or non-specified additivesas they can cause damage to the enginecooling or heating systems. Resultingcomponent damage may not be covered bythe vehicle Warranty.
Note:Automotive fluids are notinterchangeable.
It is very important to use prediluted coolantapproved to the correct specification in orderto avoid plugging the small passageways inthe engine cooling system. See Capacitiesand Specifications (page 408). Do not mixdifferent colors or types of coolant in yourvehicle. Mixing of engine coolants or usingan incorrect coolant may harm the engine orcooling system components and could voidthe vehicle Warranty.
Note:If prediluted coolant is not available,use the approved concentrated coolantdiluting it to 50/50 with deionized or distilledwater. See Capacities and Specifications(page 408). Using water that has not beendeionized may contribute to depositformation, corrosion and plugging of thesmall cooling system passageways.
To top up the coolant level do the following:
1.Unscrew the cap slowly. Any pressureescapes as you unscrew the cap.
2.Add enough prediluted coolant to reachthe correct level.
Note:We do not recommend the use ofrecycled coolant.
3.Replace the coolant reservoir cap. Turnthe cap clockwise until it contacts thehard stop.
4.Check the coolant level in the coolantreservoir the next few times you driveyour vehicle. If necessary, repeat step 2.
If you have to add more than 1.1 qt (1 L) ofengine coolant per month, have your vehiclechecked as soon as possible. Operating anengine with a low level of coolant can resultin engine overheating and possible enginedamage.
In case of emergency, you can add a largeamount of water without engine coolant inorder to reach a vehicle service location.Service your vehicle as soon as possible.
Water alone, without engine coolant, cancause engine damage from corrosion,overheating or freezing.
Do not use the following as a coolantsubstitute, as they can cause engine damagefrom overheating or freezing:
•Alcohol.
•Methanol.
•Brine.
•Any coolant mixed with alcohol ormethanol antifreeze.
Do not add extra inhibitors or additives tothe coolant. These can be harmful andcompromise the corrosion protection of thecoolant.

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.
