2016 FORD F SERIES MOTORHOME AND COMMERCIAL CHASSIS fuel reserve

•It may take a short time for the needleto reach F after leaving the gas station.This is normal and depends upon theslope of the pavement at the gasstation.
•The fuel amount dispensed into thetank is a little less or more than thegauge indicated. This is normal anddepends upon the slope of thepavement at the gas station.
•If the gas station nozzle shuts offbefore the tank is full, try a differentgas pump nozzle.
•There is a small reserve left in the tankwhen the fuel gauge reaches empty.
Low Fuel Reminder
A low fuel reminder triggers when the fuelgauge needle is at one-sixteenth or about50 miles (80 km) to empty, whicheveroccurs first.
Variations:
Note:The low fuel warning and distance-to-empty warning can appear at different fuelgauge positions depending on fuel economy conditions. This variation is normal.
Distance-to-emptyFuel gauge positionDriving type (fuel economyconditions)
30 miles to 80 miles (48 kmto 129 km)1/16thHighway driving
10 miles to 35 miles (16 kmto 56 km)1/16th-1/4Severe duty driving (trailertowing, extended idle)
WARNING LAMPS AND
INDICATORS

Brake System
Illuminates when you engage theparking brake with the ignitionon.
If it illuminates when you are driving, checkthat the parking brake is not engaged. Ifthe parking brake is not engaged, thisindicates low brake fluid level or a brakesystem malfunction. Have the systemchecked immediately by your authorizeddealer.
WARNING
Driving your vehicle with the warninglamp on is dangerous. A significantdecrease in braking performancemay occur. It will take you longer to stopyour vehicle. Have your vehicle checked byyour authorized dealer immediately. Drivingextended distances with the parking brakeengaged can cause brake failure and therisk of personal injury.
Brake Reserve System (If Equipped)
Illuminates to indicate normalhydromax booster reservesystem activation when theengine is off and the service brake pedal isapplied.
This light may also illuminate momentarilyif the engine is running and the driver turnsthe steering wheel fully in one directionwhile braking.
If the light remains on while the engine isrunning, this indicates inadequate hydraulicbooster pressure or reserve pump systemfailure. Stop the vehicle as soon aspossible and seek service immediately byyour authorized dealer.
Cruise Control (If Equipped)
Illuminates when you switch thisfeature on. See Using CruiseControl (page 37).
Direction Indicator
Illuminates when the left or rightdirection indicator or the hazardwarning flasher is turned on. Ifthe indicators stay on or flash faster, checkfor a burned out bulb.
Electronic Throttle Control
Illuminates when the engine hasdefaulted to a limp-homeoperation. See your authorizeddealer as soon as possible.
Fasten Safety Belt
It will illuminate and a chime willsound to remind you to fastenyour safety belt.
High Beam
Illuminates when you switch thehigh beam headlamps on. It willflash when you use theheadlamp flasher.
Service Engine Soon
If the service engine soonindicator light stays illuminatedafter the engine is started, itindicates that the On-Board Diagnostics(OBD-II) system has detected amalfunction of the vehicle emissionscontrol system.

5.To install the cap, align the tabs on thecap with the notches on the filler pipe.
6.Turn the filler cap clockwise 1/4 of aturn clockwise until it clicks at leastonce.
If the Check Fuel Cap light or a Check FuelCap message appears in the instrumentcluster and stays on after you start theengine, you may not have installed the fuelfiller properly.
If the fuel cap light remains on, at the nextopportunity, safely pull off of the road,remove the fuel filler cap, align the capproperly and reinstall it. The check fuel caplight or Check fuel cap message may notreset immediately. It may take severaldriving cycles for the indicators to turn off.A driving cycle consists of an enginestart-up (after four or more hours with theengine off) followed by normal city andhighway driving.
FUEL CONSUMPTION
Empty reserve is the amount of fuelremaining in the tank after the fuel gaugeindicates empty. The amount of usablefuel in the empty reserve varies and shouldnot be relied upon to increase driving range.
•The usable capacity of the fuel tank isthe amount of fuel that can be addedinto the tank after the gauge indicatesempty
•The advertised capacity is the total fueltank size. See Capacities andSpecifications (page 118). It is thecombined usable capacity plus theempty reserve.
•Due to the empty reserve, you may notbe able to refuel the full amount of theadvertised capacity of the fuel tankeven when the fuel gauge reads empty.
Filling the Tank
For consistent results when filling the fueltank:
•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 tankis filled.
•Allow no more than two automaticclick-offs when filling.
Results are most accurate when the fillingmethod is consistent.
Calculating Fuel Economy
Do not measure fuel economy during thefirst 1000 miles (1600 kilometers) ofdriving (this is your engine’s break-inperiod); a more accurate measurement isobtained after 2000 miles - 3000 miles(3200 kilometers - 4800 kilometers). Also,fuel expense, frequency of fill ups or fuelgauge readings are not accurate ways tomeasure fuel economy.
1.Fill the fuel tank completely and recordthe initial odometer reading.
2.Each time you fill the tank, record theamount of fuel added.
3.After at least 3 to 5 tank fill ups, fill thefuel tank and record the currentodometer reading.
4.Subtract your initial odometer readingfrom the current odometer reading.
5.Calculate fuel economy by dividingmiles traveled by gallons used (ForMetric: Multiply liters used by 100, thendivide by kilometers traveled).

When washing:
•Take care when using a power washerto clean the engine. The high-pressurefluid could penetrate the sealed partsand cause damage.
•Do not spray a hot engine with coldwater to avoid cracking the engineblock or other engine components.
•Spray Motorcraft Engine Shampoo andDegreaser on all parts that requirecleaning and pressure rinse clean. InCanada, use Motorcraft EngineShampoo.
•Never wash or rinse the engine while itis hot or running; water in the runningengine may cause internal damage.
•Never wash or rinse any ignition coil,spark plug wire or spark plug well, orthe area in and around these locations.
•Cover the battery, power distributionbox, and air filter assembly to preventwater damage when cleaning theengine.
CLEANING THE ALLOY
WHEELS (If Equipped)
Note:Do not apply a cleaning chemical towarm or hot wheel rims and covers.
Note:Some automatic car washes maycause damage to the finish on your wheelrims and covers.
Note:Industrial-strength or heavy-dutycleaners in combination with brush agitationto remove brake dust and dirt, could wearaway the clear coat finish over a period time.
Note:Do not use hydrofluoric acid-basedor high caustic-based wheel cleaners, steelwool, fuels or strong household detergents.
Note:If you intend parking your vehicle foran extended period after cleaning thewheels with a wheel cleaner, drive yourvehicle for a few minutes before doing so.This will reduce the risk of increasedcorrosion of the brake discs.
Alloy wheels and wheel covers are coatedwith a clear coat paint finish. To maintaintheir condition we recommend that you:
•Clean the wheels weekly usingMotorcraft Wheel and Tire Cleaner.Apply using manufacturer'sinstructions.
•Use a sponge to remove heavydeposits of dirt and brake dustaccumulation.
•Rinse thoroughly with a strong streamof water when you have completed thecleaning process.
•To remove tar and grease, useMotorcraft Bug and Tar Remover.
