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 110 voltAC electrical source.
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 BLOCKHEATER
Make sure the receptacle terminals areclean and dry prior to use. Clean them witha dry cloth if necessary.
The heater uses 0.4 to 1.0 kilowatt-hoursof energy per hour of use. The system doesnot have a thermostat. It achievesmaximum temperature afterapproximately three hours of operation.Using the engine block heater longer thanthree hours does not improve systemperformance and unnecessarily useselectricity.

HYBRID ELECTRIC VEHICLEINFORMATION – FREQUENTLYASKED QUESTIONS
What should I do if the vehicle runs outof fuel and the high voltage battery isout of charge?
Refuel and start your vehicle normally.The engine will recharge the highvoltage battery.
Why does the engine sometimes startat key-on?
The vehicle's computer determines ifan engine start is required at key-on.It starts the engine when necessary forcabin heating, windshield defrost, or ifthe outside temperature is low.
Can I put E15 or E85 in my vehicle, andhow will it affect my fuel economy?
Your hybrid vehicle can use E15 (15%ethanol, 85% gasoline) fuel, but youmay notice slightly reduced fueleconomy because ethanol containsless energy per gallon than gasoline.Your hybrid vehicle is not designed touse E85 (85% ethanol).
Why does it take a long time before theengine shuts down?
There are several reasons the enginestays on for an extended amount oftime when you first start it. Onecommon reason is to make sure thatthe emissions components are warmenough to minimize tailpipe emission.As the climate gets cooler, theengine-on time is extended.
Why does my engine stay on when it isextremely cold outside?
In order to make sure that the climatecontrol system can begin heating thecabin or defrosting the windshield assoon as a driver requests it, the enginecoolant temperature has to be keptsufficiently hot. Keeping the engine onis required to maintain the correctcoolant temperature.

ENGINE OIL CAPACITY ANDSPECIFICATION
For filling information, please refer to theCapacities and Specifications section ofyour owner's manual. See Engine OilCapacity and Specification (page 367).
CHECKING THE COOLANT
When the engine is cold, check theconcentration and level of the coolant atthe intervals listed in the scheduledmaintenance information. See ScheduledMaintenance (page 450).
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 within48% to 50%, which equates to a freezepoint between -29°F (-34°C) and -35°F(-37°C). Coolant concentration should bechecked using a refractometer. We do notrecommend the use of hydrometers orcoolant test strips for measuring coolantconcentration.
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 capwith a thick cloth to prevent thepossibility of scalding and slowly removethe cap. Failure to follow this instructioncould result in personal injury.
WARNING: Do not add coolantwhen the vehicle is on or the coolingsystem is hot. Failure to follow thisinstruction could result in personal injury.

2023 Maverick (CFE) Canada/United States of America, enUSA, Edition date: 202208, First-PrintingMaintenance

WARNING: Do not add coolantfurther than the MAX mark.
WARNING: Do not put coolant inthe windshield washer reservoir. Ifsprayed on the windshield, coolant couldmake it difficult to see through thewindshield.
WARNING: Do not allow the fluidto touch your skin or eyes. If thishappens, rinse the affected areasimmediately with plenty of water andcontact 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 predilutedcoolant approved to the correctspecification in order to avoid plugging thesmall passageways in the engine coolingsystem. See Capacities andSpecifications (page 363). Do not mixdifferent colors or types of coolant in yourvehicle. Mixing of engine coolants or usingan incorrect coolant may harm the engineor cooling system components and couldvoid the vehicle Warranty.
Note:If prediluted coolant is not available,use the approved concentrated coolantdiluting it to 50/50 with deionized ordistilled water. See Capacities andSpecifications (page 363). Using water thathas not been deionized may contribute todeposit formation, corrosion and pluggingof the small cooling system passageways.
To top up the coolant level do thefollowing:
1.Unscrew the cap slowly. Any pressureescapes as you unscrew the cap.
2.Add enough prediluted coolant toreach the 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 step2.
If you have to add more than 1.1 qt (1 L) ofengine coolant per month, have yourvehicle checked as soon as possible.Operating an engine with a low level ofcoolant can result in engine overheatingand possible engine damage.
In case of emergency, you can add a largeamount of water without engine coolantin order 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 enginedamage from 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 ofthe coolant.

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%decrease the overheat protectioncharacteristics of the coolant and couldcause engine damage.
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%decrease the overheat and corrosionprotection characteristics of the coolant andcould cause engine damage.
Coolant Change
WARNING: Do not dispose ofcoolant in the household refuse or thepublic sewage system. Use an authorizedwaste disposal facility.
Change the coolant at specific mileageintervals. Refer to the scheduledmaintenance information. See NormalScheduled Maintenance (page 453).
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 ambienttemperature, vehicle load and terrain.
How Fail-Safe Cooling Works
WARNING: If you continue to driveyour vehicle when the engine isoverheating, the engine could stopwithout warning. Failure to follow thisinstruction could result in the loss ofcontrol of your vehicle.
If the engine begins to overheat,the coolant temperature gaugemoves toward the red zone:
A warning lamp illuminates anda message may appear in theinformation display.
If the engine reaches a presetover-temperature condition, the engineautomatically switches to alternatingcylinder operation. Each disabled cylinderacts as an air pump and cools the engine.
When this occurs, your vehicle stilloperates, 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, youcan re-start the engine. Have your vehiclechecked as soon as possible to minimizeengine damage.
When Fail-Safe Mode Is Activated
WARNING: Fail-safe mode is foruse during emergencies only. Operateyour vehicle in fail-safe mode only aslong as necessary to bring your vehicleto rest in a safe location and seekimmediate repairs. When in fail-safemode, your vehicle will have limited
