CHILD RESTRAINTS RECOMMENDATION
Recommended Restraint TypeChild Size, Height, Weight, or Age
Use a child restraint (sometimescalled an infant carrier, convertibleseat, or toddler seat).
Children weighing 40 lb (18 kg) or less (generallyage four or younger).
Use a belt-positioning boosterseat.
Children who have outgrown or no longer properlyfit in a child restraint (generally children who areless than 57 in (1.45 m) tall, are greater than agefour and less than age 12, and between 40 lb (18 kg)and 80 lb (36 kg) and upward to 100 lb (45 kg) ifrecommended by your child restraint manufacturer).
Use a vehicle seatbelt having thelap belt snug and low across thehips, shoulder belt centered acrossthe shoulder and chest, and seatbackrest upright.
Children who have outgrown or no longer properlyfit in a belt-positioning booster seat (generally chil-dren who are at least 57 in (1.45 m) tall or greaterthan 80 lb (36 kg) or 100 lb (45 kg) if recommendedby child restraint manufacturer).
You are required by law to properly usechild restraints for infants and toddlers inthe United States, Canada and Mexico.
Many states and provinces require thatsmall children use approved booster seatsuntil they reach age eight, a height of 57 in(1.45 m) tall, or 80 lb (36 kg). Check yourlocal and state or provincial laws forspecific requirements about the safety ofchildren in your vehicle.
When possible, properly restrain children12 years of age and under in a rear seatingposition of your vehicle. Accident statisticssuggest that children are safer whenproperly restrained in the rear seatingpositions than in a front seating position.
When installing a rear facing child restraint,adjust the vehicle seats to avoidinterference between the child restraintand the vehicle seat in front of the childrestraint.

STARTING AND STOPPING
THE ENGINE – PRECAUTIONS
WARNING: Extended idling at highengine speeds can produce very hightemperatures in the engine and exhaustsystem, creating the risk of fire or otherdamage.
WARNING: Do not park, idle ordrive your vehicle on dry grass or otherdry ground cover. The emission systemheats up the engine compartment andexhaust system, creating the risk of fire.
WARNING: Do not start the enginein a closed garage or in other enclosedareas. Exhaust fumes are toxic. Alwaysopen the garage door before you startthe engine. Failure to follow thisinstruction could result in personal injuryor death.
WARNING: Do not use startingfluid, for example ether, in the air intakesystem. Such fluid could causeimmediate explosive damage to theengine and possible personal injury.
WARNING: Exhaust leaks mayresult in entry of harmful and potentiallylethal fumes into the passengercompartment. If you smell exhaustfumes inside your vehicle, have yourvehicle inspected immediately. Do notdrive if you smell exhaust fumes.
The powertrain control system meets allCanadian interference-causing equipmentstandard requirements regulating theimpulse electrical field or radio noise.
Note:If you use your vehicle regularly abovethe altitude of 5,000 ft (1,524 m) and underthe temperature of -4.0°F (-20°C), it isrecommended to use the alternative engineoil. See Capacities and Specifications(page 520).
If you stop your vehicle and leave theengine idling for long periods, werecommend that you do one of thefollowing:
•Open the windows at least 1 in(2.5 cm).
•Set your climate control to outside air.

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 a Trailer(page 365).
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.
We recommend Top Tier detergentgasolines, where available to help minimizeengine deposits and maintain optimalvehicle and engine performance.
For additional information, visitwww.toptiergas.com.
Note:Use of any fuel for which the vehiclewas not designed can impair the emissioncontrol system, cause loss of vehicleperformance, and cause damage to theengine which may not be covered by thevehicle Warranty.
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, which is amanganese-based fuel additive, will impairengine performance and affect theemission control system.
SELECTING THE CORRECT FUELFOR COLD WEATHER
Choosing the Right Fuel: VehiclesOperated Where Ultra Low SulfurDiesel Fuel Is Required (UnitedStates/Canada/Puerto Rico/U.S.Virgin Islands And Other Locales)
Note:Your Warranty will not cover damagecaused by using an improper type of fuel orfuel additive.
Note:Do not blend used engine oil withdiesel fuel under any circumstances.Blending used oil with the fuel significantlyincreases your vehicle’s exhaust emissionsand reduce engine life due to increasedinternal wear.
We recommend Top Tier diesel fuel whereavailable to help minimize engine depositsand maintain optimal vehicle and engineperformance.
For additional information, visitwww.toptiergas.com.
You should use ultra-low sulfur diesel fueldesignated as number 1-D or 2-D with amaximum of 15-ppm sulfur in your dieselvehicle. You can operate your vehicle ondiesel fuels containing up to 20%biodiesel, also known as B20. These fuelsshould meet the ASTM D975 diesel or theASTM D7467 B6-B20 biodiesel industryspecifications. Outside of North America,use fuels meeting EN590 or equivalentlocal market standard.

•Follow the recommended servicemaintenance intervals. See GeneralMaintenance Information (page 594).
•Do not store biodiesel fuel in the fueltank for more than 1 month.
•Consider changing brands or reducingbiodiesel content if you have coldtemperature fuel gelling issues or afrequently appearing LOW FUELPRESSURE message.
Use of biodiesel in concentrations greaterthan 20% can cause damage to yourvehicle, including engine and/or exhaustafter-treatment hardware (exhaustcatalyst and particulate filter) failures.Concentrations greater than 20% can alsocause fuel filter restrictions that couldresult in a lack of power or damage to fuelsystem components, including fuel pumpand fuel injector failures.
We recommend SAE 5W-40 oil for fuelswith greater than 5% biodiesel (B5). Formore information about oil changeintervals and other maintenance whenoperating on biodiesel. See SpecialOperating Conditions ScheduledMaintenance (page 603).
Look for a label on the fuel pump toconfirm the amount of biodiesel containedin diesel fuel. Ask the service stationattendant to confirm the biodiesel contentof diesel fuel, if you do not see a label onthe fuel pump.
If you plan to park or store your vehicle formore than 1 month, then you should emptyyour vehicle fuel tank of biodiesel fuel. Youshould fill the tank with a purepetroleum-based diesel fuel and run yourvehicle for a minimum of 30 minutes.
Note:Degraded or oxidized biodiesel candamage fuel system seals and plastics andcorrode steel parts.
During cold weather, if you have problemsoperating on biodiesel, you may need touse diesel fuel with lower biodieselcontent, try another brand or discontinuethe use of biodiesel.
Diesel Fuel Additives
It should not be necessary to add anyaftermarket additives to your fuel if youuse a high-quality diesel fuel that conformsto ASTM industry specifications.Aftermarket additives can damage the fuelinjector system or engine.
Use Motorcraft® cetane booster or anequivalent cetane booster additive if yoususpect fuel has low cetane. UseMotorcraft® anti-gel and performanceimprover or an equivalent additive if thereis fuel gelling.
Do not use alcohol-based additives toimprove cetane quality, to prevent fuelgelling or any other use. The use of alcoholadditives could result in damage to the fuelinjectors and system.
Your Warranty may not cover repairsneeded to correct the effects of using anaftermarket product that does not meetour specifications in your fuel.
RUNNING OUT OF FUEL
FILLING A PORTABLE FUELCONTAINER

HOW DOES FOUR-WHEEL
DRIVE WORK
Using the Electronic Shift On theFly System (If Equipped)
This four-wheel drive system utilizes a2-speed Electronic Shift On the Fly (ESOF)transfer case which is also known as apart-time system. This system offers thedriver two-wheel drive high, four-wheeldrive high, and four-wheel drive low asavailable modes of operation. When youselect either four-wheel drive high orfour-wheel drive low, the system providesmechanically locked four-wheel drivepower to both the front and rear wheelsfor use in off-road or slippery conditionssuch as deep snow, sand or mud. Whenyou select four-wheel drive low, the systemprovides additional gearing for increasedtorque multiplication for conditions likedeep sand, steep slopes, or pulling heavyobjects. Additionally, the system is capableof recreational flat towing by putting thetransfer case into a neutral position. SeeRecreationally Towing Your Vehicle(page 427).
There is further information available ondriving in unique driving conditions. SeeOff-Road Driving (page 412).
Your vehicle has manual hub locks on thedriver side and passenger side of yourvehicle. For proper operation, make surethat each hub is fully engaged and thatboth hub locks are set to the same position(both set to lock or both set to auto). Toengage lock, turn the hub locks completelyclockwise. To engage auto, turn the hublocks completely counterclockwise.
The ESOF four-wheel drive system:
•Provides 4x4 High engagement anddisengagement while the vehicle ismoving.
•Operates by a push button controllocated on the instrument panel thatallows you select 4x2, 4x4 High or 4x4Low operation.
•Uses auto-manual hub locks. When setto auto, the hubs engage anddisengage automatically based on the4x4 mode you select. When set to lock,the hubs remain engaged at all times.
•Increases fuel economy when used inthe hub lock's recommended automode.
Note:Auto-manual hub locks manuallylock by rotating the hub lock control fromauto to lock.
Note:Hub locks should be in auto modewhen in 4x2 mode. If hub locks are in lockmode in 4x2 mode, there will be additionalnoise from the front axle.
