Programming the Garage Door Openerto your Gate Opener Motor
Gate Operator / Canadian Programming
Canadian radio-frequency laws requiretransmitter signals to time-out (or quit) afterseveral seconds of transmission – which maynot be long enough for HomeLink to pick upthe signal during programming. Similar tothis Canadian law, some U.S. gate operatorsare designed to time-out in the same manner.
Note:If programming a garage door openeror gate operator, it is advised that youunplug the device during the cycling processto prevent possible overheating.
1.Press and release your handheldtransmitter, every two seconds, until theHomeLink indicator flashes rapidly or iscontinuously on.
2.Release the handheld transmitter button.
3.Press and hold the HomeLink functionbutton you want to program for twoseconds, then release. You may need todo this twice to activate the door.
Note:If the indicator stays on, theprogramming is complete.
Note:If the HomeLink indicator flashesrapidly, repeat Step 3.
4.To program additional buttons, repeatSteps 1–4.

ELECTRIC POWER STEERING
HOW DOES ELECTRIC POWERSTEERING WORK
The electric power steering system assiststhe brake system to help operate advancedstability control and accident avoidancesystems.
If your vehicle loses electrical power ordetects a concern when you are driving thesystem switches off and you retain normalsteering function. Additionally, whenever thebattery is disconnected or a new battery isinstalled, you must drive your vehicle a shortdistance before the system relearns thestrategy and reactivates all systems.
ELECTRIC POWER STEERINGPRECAUTIONS
WARNING: The electric powersteering system has diagnostic checks thatcontinuously monitor the system. If a faultis detected, a message displays in theinformation display. Stop your vehicle assoon as it is safe to do so. Switch thevehicle off. After at least 10 seconds, switchthe vehicle on and watch the informationdisplay for a steering system warningmessage. If a steering system warningmessage returns, have the system checkedas soon as possible.
WARNING: If the system detects anerror, you may not feel a difference in thesteering, however a serious condition mayexist. Have your vehicle checked as soonas possible. Failure to do so may result inloss of steering control.
Adapt your speed and driving behavioraccording to reduced steering assist.
Extreme continuous steering may increasethe effort to steer. This occurs to preventinternal overheating and damage to thesteering system. If this occurs, you will notlose the ability to steer your vehicle manuallynor will it cause damage to the system.Normal steering and driving allows thesystem to cool down and steering assistreturns to normal.
Note:There is no fluid reservoir to check orfill.

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.
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 467). 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 467). 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.
419
2023 Navigator (TB9) Canada/United States of America, enUSA, Edition date: 202207, DOMMaintenance

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 533).
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.
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.
421
2023 Navigator (TB9) Canada/United States of America, enUSA, Edition date: 202207, DOMMaintenanceE103308 E67028

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).
