2018 LINCOLN MKX coolant reservoir

Low Fuel Reminder
A low fuel level reminder displays andsounds when the distance to empty reaches50 mi (80 km) to empty for MyKey, and at35 mi (60 km), 25 mi (40 km), 10 mi (20 km)and 0 mi (0 km) for all vehicle keys.
Variations:
Note:The low fuel reminder can appear atdifferent fuel gauge positions depending onfuel economy conditions. This variation isnormal.
Engine Coolant Temperature Gauge
Indicates engine coolant temperature. Atnormal operating temperature, the levelindicator will be in the normal range. If theengine coolant temperature exceeds thenormal range, stop the vehicle as soon assafely possible, switch off the engine and letthe engine cool.
WARNING
Never remove the coolant reservoircap when the engine is running or hot.
WARNING LAMPS AND
INDICATORS
The following warning lamps and indicatorsalert you to a vehicle condition that maybecome serious. Some lamps illuminatewhen you start your vehicle to make surethey work. If any lamps remain on afterstarting your vehicle, refer to the respectivesystem warning lamp for further information.
Note:Some warning indicators appear inthe information display and operate thesame as a warning lamp but do notilluminate when you start your vehicle.
Adaptive Cruise Control Indicator (If
Equipped)
It illuminates when you switch thesystem on.
It illuminates white when thesystem is in standby mode. It illuminatesgreen when you set the adaptive cruisespeed.
See Using Adaptive Cruise Control (page230).
Adaptive Steering (If Equipped)
The adaptive steering systemindicator illuminates if the systemdetects a fault during thecontinuous diagnostic checks.
Adaptive Steering Initialization (yellow,flashing): The adaptive steering system hasdetected a difference between steeringwheel angle and the desired road wheelangle. The steering wheel adjusts itself tocorrect this difference. This adjustment ispart of normal system operation.
Adaptive Steering Off (yellow, solid): Theadaptive steering system is off. It is possiblethat the steering wheel may not be straightwhen the vehicle is driving straight ahead. Ifthis message persists, see an authorizeddealer.
Adaptive Steering Loss (red, solid): Theadaptive steering system integrity cannot beverified. Do not drive the vehicle and contactan authorized dealer immediately. SeeSteering (page 250).

ENGINE COOLANT CHECK
WARNINGS
Never remove the coolant reservoircap when the engine is running or hot.
Do not put coolant in the windshieldwasher reservoir. If sprayed on thewindshield, coolant could make it difficult tosee through the windshield.
To reduce the risk of personal injury,make sure the engine is cool beforeunscrewing the coolant pressure relief cap.The cooling system is under pressure. Steamand hot liquid can come out forcefully whenyou loosen the cap slightly.
WARNINGS
Do not add coolant further than theMAX mark.
When the engine is cold, check theconcentration and level of the coolant at theintervals listed in the scheduled maintenanceinformation. See Scheduled Maintenance(page 517).
Note:Make sure that the coolant level isbetween the MIN and MAX marks on thecoolant reservoir.
Note: Coolant expands when it is hot. Thelevel may extend beyond the MAX mark.
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
WARNINGS
Do not add engine coolant when theengine is hot. Failure to follow thisinstruction could result in personal injury.
Never remove the coolant reservoircap when the engine is running or hot.
Note: Automotive fluids are notinterchangeable. Take care not to putengine coolant in the windshield washer fluidreservoir or windshield washer fluid in theengine coolant reservoir.
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.
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 381). 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 may not becovered by the vehicle Warranty.
Note:If prediluted coolant is not available,use the approved concentrated coolantdiluting it to 50/50 with distilled water. SeeCapacities and Specifications (page 381).Using water that has not been deionisedmay contribute to deposit formation,corrosion and plugging of the small coolingsystem passageways.
Note: Coolants marketed for all makes andmodels may not be approved to Fordspecifications and may cause damage tothe cooling system. Resulting componentdamage may not be covered by the vehicleWarranty.
If the coolant level is at or below theminimum mark, add prediluted coolantimmediately.
To top up the coolant level do the following:
1. Unscrew the cap slowly. Any pressureescapes as you unscrew the cap.
2. Add prediluted coolant approved to thecorrect specification. See Capacities andSpecifications (page 381).
3.Add enough prediluted coolant to reachthe correct level.
4. Replace the coolant reservoir cap, turnit clockwise until you feel a strongresistance.
5. Check the coolant level in the coolantreservoir the next few times you driveyour vehicle. If necessary, add enoughprediluted engine coolant to bring thecoolant level to the correct level.
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.

Maintenance

Coolant Change
At specific mileage intervals, as listed in thescheduled maintenance information, thecoolant should be changed. Add predilutedcoolant approved to the correct specification.See Capacities and Specifications (page381).
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
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
WARNINGS
Fail-safe mode is for use duringemergencies only. Operate yourvehicle in fail-safe mode only as long asnecessary to bring your vehicle to rest in asafe location and seek immediate repairs.When in fail-safe mode, your vehicle will havelimited power, will not be able to maintainhigh-speed operation, and may completelyshut down without warning, potentially losingengine power, power steering assist, andpower brake assist, which may increase thepossibility of a crash resulting in seriousinjury.
Never remove the coolant reservoircap when the engine is running or hot.
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 mayoperate poorly.
Remember that the engine is capable ofautomatically shutting down to preventengine damage. In this situation:
