SAFETY PRECAUTIONS
WARNINGS
Do not overfill the fuel tank. Thepressure in an overfilled tank maycause leakage and lead to fuel spray andfire.
The fuel system may be underpressure. If you hear a hissing soundnear the fuel filler inlet, do not refuel until thesound stops. Otherwise, fuel may spray out,which could cause serious personal injury.
Fuels can cause serious injury or deathif misused or mishandled.
Fuel may contain benzene, which is acancer-causing agent.
When refueling always shut the engineoff and never allow sparks or openflames near the fuel tank filler valve. Neversmoke or use a cell phone while refueling.Fuel vapor is extremely hazardous undercertain conditions. Avoid inhaling excessfumes.
Follow these guidelines when refueling:
•Extinguish all smoking materials and anyopen flames before refueling yourvehicle.
•Always switch the engine off beforerefueling.
•Automotive fuels can be harmful or fatalif swallowed. Fuel is highly toxic and ifswallowed can cause death or permanentinjury. If fuel is swallowed immediatelycall a physician, even if no symptoms areimmediately apparent. The toxic effectsof fuel may not be apparent for hours.
•Avoid inhaling fuel vapors. Inhaling fuelvapor can lead to eye and respiratorytract irritation. In severe cases, excessiveor prolonged breathing of fuel vapor cancause serious illness and permanentinjury.
•Avoid getting fuel in your eyes. If yousplash fuel in your eyes, immediatelyremove contact lenses (if worn), flush withwater for 15 minutes and seek medicalattention. Failure to seek proper medicalattention could lead to permanent injury.
•Fuels can be harmful if absorbed throughthe skin. If you splash fuel on your skin,clothing or both, promptly removecontaminated clothing and thoroughlywash your skin with soap and water.Repeated or prolonged skin contactcauses skin irritation.
•Be particularly careful if you are takingAntabuse or other forms of Disulfiram forthe treatment of alcoholism. Breathingfuel vapors could cause an adversereaction, serious personal injury orsickness. Immediately call a physician ifyou experience any adverse reactions.
FUEL QUALITY
Choosing the Right Fuel
168
MKZ (CC9) Canada/United States of America, enUSA, Edition date: 201706, First Printing
Fuel and RefuelingE161513

We recommend regular unleaded gasolinewith a minimum pump (R+M)/2 octane ratingof 87. Some stations offer fuels posted asregular with an octane rating below 87,particularly in high altitude areas. We do notrecommend fuels with an octane ratingbelow 87. To provide improved performance,we recommend premium fuel for severe dutyusage such as trailer tow.
Do not use any fuel other than thoserecommended because they could lead toengine damage that may not be covered bythe vehicle Warranty.
Note:Use of any fuel other than thoserecommended can impair the emissioncontrol system and cause a loss of vehicleperformance.
Do not use:
•Diesel fuel.
•Fuels containing kerosene or paraffin.
•Fuel containing more than 15% ethanolor E85 fuel.
•Fuels containing methanol.
•Fuels containing metallic-based additives,including manganese-based compounds.
•Fuels containing the octane boosteradditive, methylcyclopentadienylmanganese tricarbonyl (MMT).
•Leaded fuel (using leaded fuel isprohibited by law).
The use of fuels with metallic compoundssuch as methylcyclopentadienyl manganesetricarbonyl (commonly known as MMT), whichis a manganese-based fuel additive, willimpair engine performance and affect theemission control system.
Do not be concerned if the enginesometimes knocks lightly. However, if theengine knocks heavily while using fuel withthe recommended octane rating, contact anauthorized dealer to prevent any enginedamage.
FUEL FILLER FUNNEL LOCATION
The fuel filler funnel is under the luggagecompartment floor covering.RUNNING OUT OF FUEL
Running out of fuel can cause damage notcovered by the vehicle Warranty.

Fuel and RefuelingE162864

If your vehicle runs out of fuel:
•Add a minimum of 1.3 gal (5 L) of fuel torestart the engine.
•You may need to switch the ignition fromoff to on several times after refueling toallow the fuel system to pump the fuelfrom the tank to the engine. Whenrestarting, cranking time takes a fewseconds longer than normal.
Note:If your vehicle is on a steep slope,more fuel may be required.
Filling a Portable Fuel Container
WARNING
Flow of fuel through a fuel pump nozzlecan produce static electricity. This cancause a fire if you are filling an ungroundedfuel container.
Use the following guidelines to avoidelectrostatic charge build-up, which canproduce a spark, when filling an ungroundedfuel container:
•Only use an approved fuel container totransfer fuel to your vehicle. Place thecontainer on the ground when filling it.
•Do not fill a fuel container when it isinside your vehicle (including the cargoarea).
•Keep the fuel pump nozzle in contactwith the fuel container when filling it.
•Do not use a device that holds the fuelpump nozzle lever in the fill position.
Adding Fuel From a Portable FuelContainer
WARNINGS
Do not insert the nozzle of a fuelcontainer or an aftermarket funnel intothe fuel filler neck. This may damage the fuelsystem filler neck or its seal and cause fuelto run onto the ground.
WARNINGS
Do not try to pry open or push openthe capless fuel system with foreignobjects. This could damage the fuel systemand its seal and cause injury to you or others.
Do not dispose of fuel in the householdrefuse or the public sewage system.Use an authorized waste disposal facility.
When refueling the vehicle fuel tank from afuel container, use the fuel filler funnelincluded with your vehicle. See Fuel FillerFunnel Location (page 169).
Note:Do not use aftermarket funnels as theymay not work with the capless fuel systemand can damage it.
When refueling the vehicle fuel tank from afuel container, do the following:
1. Fully open the fuel filler door.
2. Fully insert the fuel filler funnel into thefuel filler inlet.

6. Clean the fuel filler funnel and place itback in your vehicle or correctly disposeof it.
Note:Extra funnels can be purchased froman authorized dealer if you choose todispose of the funnel.
REFUELING
WARNINGS
When refueling always shut the engineoff and never allow sparks or openflames near the fuel tank filler valve. Neversmoke or use a cell phone while refueling.Fuel vapor is extremely hazardous undercertain conditions. Avoid inhaling excessfumes.
The fuel system may be underpressure. If you hear a hissing soundnear the fuel filler inlet, do not refuel until thesound stops. Otherwise, fuel may spray out,which could cause serious personal injury.
Do not remove the fuel pump nozzlefrom its fully inserted position whenrefueling.
Do not overfill the fuel tank. Thepressure in an overfilled tank maycause leakage and lead to fuel spray andfire.
WARNINGS
Stop refueling when the fuel pumpnozzle automatically shuts off for thefirst time. Failure to follow this will fill theexpansion space in the fuel tank and couldlead to fuel overflowing.
Wait at least 10 seconds beforeremoving the fuel pump nozzle to allowany residual fuel to drain into the fuel tank.
Do not try to pry open or push openthe capless fuel system with foreignobjects. This could damage the fuel systemand its seal and cause injury to you or others.

3. Pull the manual override lever.
4. Switch the ignition off.
5. Complete the refueling process within20 minutes.
FUEL CONSUMPTION
The advertised capacity is the maximumamount of fuel that you can add to the fueltank after running out of fuel. Included in theadvertised capacity is an empty reserve. Theempty reserve is an unspecified amount offuel that remains in the fuel tank when thefuel gauge indicates empty.
Note:The amount of fuel in the emptyreserve varies and should not be relied uponto increase driving range.
Filling the Fuel Tank
For consistent results when refueling:
•Turn the ignition off before fueling; aninaccurate reading results if the engineis left running.
•Use the same fill rate (low-medium-high)each time the tank is filled.
•Allow no more than one automaticshut-off when refueling.
Results are most accurate when the fillingmethod is consistent.
Calculating Fuel Economy
Do not measure fuel economy during thefirst 1,000 mi (1,600 km) of driving (this is yourengine’s break-in period). A more accuratemeasurement is obtained after 2,000 mi(3,200 km) to 3,000 mi (4,800 km). Also, fuelexpense, frequency of fill ups or fuel gaugereadings are not accurate ways to measurefuel economy.
1. Fill the fuel tank completely and recordthe initial odometer reading.
2.Each time you fill the fuel tank, record theamount of fuel added.
3. After at least three fill ups, fill the fueltank and record the current odometerreading.
4. Subtract your initial odometer readingfrom the current odometer reading.
To calculate L/100 km (liters per 100kilometers) fuel consumption, multiply theliters used by 100, then divide by kilometerstraveled. To calculate MPG (miles per gallon)fuel consumption, divide miles traveled bygallons used.
Keep a record for at least one month andrecord the type of driving (city or highway). This provides an accurate estimate of yourvehicle's fuel economy under current drivingconditions. Keeping records during summerand winter will show how temperatureimpacts fuel economy.

EMISSION LAW
WARNING
Do not remove or alter the originalequipment floor covering or insulationbetween it and the metal floor of the vehicle.The floor covering and insulation protectoccupants of the vehicle from the engineand exhaust system heat and noise. Onvehicles with no original equipment floorcovering insulation, do not carry passengersin a manner that permits prolonged skincontact with the metal floor. Failure to followthese instructions may result in fire orpersonal injury.
U.S. federal laws and certain state lawsprohibit removing or rendering inoperativeemission control system components. Similarfederal or provincial laws may apply inCanada. We do not approve of any vehiclemodification without first determiningapplicable laws.
Tampering with emissions controlsystems including related sensorsor the Diesel Exhaust Fluid systemcan result in reduced engine power and theillumination of the service engine soon light.
Tampering With a Noise ControlSystem
Federal laws prohibit the following acts:
•Removal or rendering inoperative by anyperson other than for purposes ofmaintenance.
•Repair or replacement of any device orelement of the design incorporated intoa new vehicle for the purpose of noisecontrol prior to its sale or delivery to theultimate purchaser or while it is in use.
•The use of the vehicle after any personremoves or renders inoperative anydevice or element of the design.
The U.S. Environmental Protection Agencymay presume to constitute tampering asfollows:
•Removal of hood blanket, fender apronabsorbers, fender apron barriers,underbody noise shields or acousticallyabsorptive material.
•Tampering or rendering inoperative theengine speed governor, to allow enginespeed to exceed manufacturerspecifications.
If the engine does not start, runs rough,experiences a decrease in engineperformance, experiences excess fuelconsumption or produces excessive exhaustsmoke, check for the following:
•A plugged or disconnected air inletsystem hose.
•A plugged engine air filter element.
•Water in the fuel filter and waterseparator.
•A clogged fuel filter.
•Contaminated fuel.
•Air in the fuel system, due to looseconnections.

Engine Emission Control

•An open or pinched sensor hose.
•Incorrect engine oil level.
•Incorrect fuel for climatic conditions.
•Incorrect engine oil viscosity for climacticconditions.
Note:Some vehicles have a lifetime fuel filterthat is integrated with the fuel tank. Regularmaintenance or replacement is not needed.
Note:If these checks do not help you correctthe concern, have your vehicle checked assoon as possible.
Noise Emissions Warranty, ProhibitedTampering Acts and Maintenance
On January 1, 1978, Federal regulationbecame effective governing the noiseemission on trucks over 10,000 lb (4,536 kg)Gross Vehicle Weight Rating (GVWR). Thepreceding statements concerning prohibitedtampering acts and maintenance, and thenoise warranty found in the Warranty Guide,are applicable to complete chassis cabs over10,000 lb (4,536 kg) GVWR.
CATALYTIC CONVERTER
WARNINGS
Do not park, idle or drive your vehicleon dry grass or other dry ground cover.The emission system heats up the enginecompartment and exhaust system, creatingthe risk of fire.
The normal operating temperature ofthe exhaust system is very high. Neverwork around or attempt to repair any part ofthe exhaust system until it has cooled. Usespecial care when working around thecatalytic converter. The catalytic converterheats up to a very high temperature afteronly a short period of engine operation andstays hot after the engine is switched off.
Exhaust leaks may result in entry ofharmful and potentially lethal fumesinto the passenger compartment. If you smellexhaust fumes inside your vehicle, have yourvehicle inspected immediately. Do not driveif you smell exhaust fumes.
Your vehicle has various emission controlcomponents and a catalytic converter thatenables it to comply with applicable exhaustemission standards.
To make sure that the catalytic converter andother emission control components continueto work properly:
•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 the Vehicle (page 268).
•Use only the specified fuel listed.
•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:Resulting component damage maynot be covered by the vehicle Warranty.
