Some fuel stations, particularly those inhigh altitude areas, offer fuels posted asregular unleaded gasoline with an octanerating below 87. We do not recommendthese fuels.
For best overall vehicle and engineperformance, premium fuel with an octanerating of 91 or higher is recommended. Theperformance gained by using premium fuelis most noticeable in hot weather as wellas other conditions, for example whentowing a trailer. See Towing (page 182).
Do not be concerned if the enginesometimes knocks lightly. However, if theengine knocks heavily while using fuel withthe recommended octane rating, contactan authorized dealer to prevent any enginedamage.
Do not use any fuel other than thoserecommended because they could lead toengine damage that will 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-basedadditives, including manganese-basedcompounds.
•Fuels containing the octane boosteradditive, methylcyclopentadienylmanganese tricarbonyl (MMT).
•Leaded fuel, using leaded fuel isprohibited by law.
The use of fuels with metallic compoundssuch as methylcyclopentadienylmanganese tricarbonyl (commonly knownas MMT), which is a manganese-basedfuel additive, will impair engineperformance and affect the emissioncontrol system.
We recommend Top Tier detergentgasolines to help minimize engine depositsand maintain optimal vehicle and engineperformance. For additional information,refer to www.toptiergas.com.
FUEL FILLER FUNNEL
LOCATION
The fuel filler funnel is in the glovecompartment.
RUNNING OUT OF FUEL
Running out of fuel can cause damage notcovered by the vehicle Warranty.
If your vehicle runs out of fuel:
•Add a minimum of 1.3 gal (5 L) of fuelto restart the engine.
•You may need to switch the ignitionfrom off to on several times afterrefueling to allow the fuel system topump the fuel from the tank to theengine. When restarting, cranking timetakes a few seconds longer thannormal.
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 pumpnozzle can produce static electricity.This can cause a fire if you are fillingan ungrounded fuel container.

CATALYTIC CONVERTER
WARNINGS
Do not park, idle or drive your vehicleon dry grass or other dry groundcover. The emission system heats upthe engine compartment and exhaustsystem, creating the risk of fire.
The normal operating temperatureof the exhaust system is very high.Never work around or attempt torepair any part of the exhaust system untilit has cooled. Use special care whenworking around the catalytic converter.The catalytic converter heats up to a veryhigh temperature after only a short periodof engine operation and stays hot after theengine is switched off.
WARNINGS
Exhaust leaks may result in entry ofharmful and potentially lethal fumesinto the passenger compartment. Ifyou smell exhaust fumes inside yourvehicle, have your vehicle inspectedimmediately. Do not drive if you smellexhaust fumes.
Your vehicle has various emission controlcomponents and a catalytic converter thatenables it to comply with applicableexhaust emission standards.
To make sure that the catalytic converterand other emission control componentscontinue to 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 190).
•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.
The scheduled maintenance items listedin scheduled maintenance information areessential to the life and performance ofyour vehicle and to its emissions system.
If you use anything other than Ford,Motorcraft or Ford-authorized parts formaintenance replacements or for serviceof components affecting emission control,such non-Ford parts should be equivalentto genuine Ford Motor Company parts inperformance and durability.

Your vehicle may not pass the I/M test ifthe service engine soon indicator is on ornot working properly (bulb is burned out),or if the OBD-II system has determinedthat some of the emission control systemshave not been properly checked. In thiscase, the vehicle is not ready for I/Mtesting.
If the vehicle’s engine or transmission hasjust been serviced, or the battery hasrecently run down or been replaced, theOBD-II system may indicate that thevehicle is not ready for I/M testing. Todetermine if the vehicle is ready for I/Mtesting, turn the ignition key to the onposition for 15 seconds without crankingthe engine. If the service engine soonindicator blinks eight times, it means thatthe vehicle is not ready for I/M testing; ifthe service engine soon indicator stays onsolid, it means that your vehicle is readyfor I/M testing.
The OBD-II system checks the emissioncontrol system during normal driving. Acomplete check may take several days.
If the vehicle is not ready for I/M testing,you can perform the following driving cycleconsisting of mixed city and highwaydriving:
1.15 minutes of steady driving on anexpressway or highway followed by 20minutes of stop-and-go driving with atleast four 30-second idle periods.
2.Allow your vehicle to sit for at leasteight hours with the ignition off. Then,start the vehicle and complete theabove driving cycle. The vehicle mustwarm up to its normal operatingtemperature. Once started, do not turnoff the vehicle until the above drivingcycle is complete.

GENERAL INFORMATION
Wet brakes result in reduced brakingefficiency. Gently press the brake pedal afew times when driving from a car wash orstanding water to dry the brakes.
Note: Occasional brake noise is normal. Ifa metal-to-metal, continuous grinding orcontinuous squeal sound is present, thebrake linings may be worn-out. Have thesystem checked by an authorized dealer. Ifyour vehicle has continuous vibration orshudder in the steering wheel while braking,have it checked by an authorized dealer.
Note:Brake dust may accumulate on thewheels, even under normal drivingconditions. Some dust is inevitable as thebrakes wear and does not contribute tobrake noise. See Cleaning the Wheels(page 241).
Note:Depending on applicable laws andregulations in the country for which yourvehicle was originally built, the brake lampscould flash during heavy braking. Followingthis, the hazard lights could also flash whenyour vehicle comes to a stop.
Brake Over Accelerator
In the event that the accelerator pedalbecomes stuck or entrapped, apply steadyand firm pressure to the brake pedal toslow your vehicle and reduce enginepower. If you experience this condition,apply the brakes and bring your vehicle toa safe stop. Move the transmission to park(P), switch the engine off and apply theparking brake. Inspect the acceleratorpedal for any interference. If none arefound and the condition persists, have yourvehicle towed to the nearest authorizeddealer.
Brake Assist
Brake assist detects when you rapidlybrake by measuring the rate at which youpress the brake pedal. It providesmaximum braking efficiency as long as youpress the pedal, and can reduce stoppingdistances in critical situations
Anti-Lock Brake System
This system helps you maintain steeringcontrol during emergency stops by keepingthe brakes from locking.
If it illuminates when you aredriving, this indicates amalfunction. Your vehiclecontinues to have normal braking withoutthe anti-lock brake system function. Haveyour vehicle checked as soon as possible.
It also momentarily illuminates when youswitch the ignition on to confirm the lampis functional. If it does not illuminate whenyou switch the ignition on, or begins toflash at any time, have the system checkedby an authorized dealer.
It illuminates when you engagethe parking brake and theignition is on.
If it illuminates when your vehicle ismoving, make sure the parking brake isdisengaged. If the parking brake isdisengaged, this indicates low brake fluidlevel or a brake system fault. Have yourvehicle immediately checked.
It also momentarily illuminates when youswitch the ignition on to confirm the lampis functional. If it does not illuminate whenyou switch the ignition on, or begins toflash at any time, have the system checkedby an authorized dealer.

The system makes it easier to pull awaywhen your vehicle is on a slope without theneed to use the parking brake.
When the system activates, your vehicleremains stationary on a slope for a fewseconds after you release the brake pedal.This allows you time to move your footfrom the brake to the accelerator pedal.The brakes release when the engine hasdeveloped sufficient torque to prevent yourvehicle from rolling down the slope. Thisis an advantage when pulling away on aslope, for example from a car park ramp,traffic lights or when reversing uphill intoa parking space.
The system activates on any slope thatcauses your vehicle to roll.
Note:There is no warning lamp to indicatethe system is either on or off.
Using Hill Start Assist
1.Press the brake pedal to bring yourvehicle to a complete standstill. Keepthe brake pedal pressed and shift intofirst gear when facing uphill or reverse(R) when facing downhill.
2.The system activates if the sensorsdetect that your vehicle is on a slope.
3.When you remove your foot from thebrake pedal, your vehicle remains onthe slope without rolling away for a fewseconds. This hold time increases if youare in the process of driving off.
4.Pull away in the normal manner.
