FUEL QUALITY
Choosing the Right Fuel
Your vehicle is designed to operate onregular unleaded gasoline with a minimumpump (R+M)/2 octane rating of 87.
Some fuel stations, particularly those in highaltitude areas, offer fuels posted as regularunleaded gasoline with an octane ratingbelow 87. The use of these fuels could resultin engine damage that will not be coveredby the vehicle warranty.
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 well asother conditions, for example when towinga trailer. See Towing (page 298).
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.
We recommend Top Tier detergentgasolines, where available to help minimizeengine deposits and maintain optimal vehicleand engine performance. For additionalinformation, refer to www.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-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.
FUEL FILLER FUNNEL LOCATION
The fuel filler funnel is in the spare wheelstorage tray.

Shifting To or From 4L - 4X4 LOW
Note:4L mode is not intended for use on drypavement.
1. Bring the vehicle to a rolling speed of3 mph (5 km/h) or less.
2. Place the gearshift in neutral (N).
3. Rotate the drive mode knob to desiredmode.
The information display shows a messageindicating a 4X4 shift is in progress. Theinformation display shows the system modeselected. If any of the previous shiftconditions are not present, the shift does notoccur and the information display shows theinformation guiding the driver through theproper shifting procedures. If the previousconditions are not satisfied in 30 seconds,the system reverts back to the previous 4WDmode or drive mode.
If Shift Delayed Pull Forward displays in theinformation display, transfer case gear toothblockage is present. To alleviate thiscondition, place the transmission in a forwardgear, move the vehicle forwardapproximately 5 ft (2 m), and shift thetransmission back to neutral (N) to allow thetransfer case to complete the range shift.
Operating 4WD Vehicles With Spareor Mismatched Tires
On four-wheel drive vehicles, the size of thespare tire can affect the 4X4 system. If thereis a significant difference between the sizeof the spare tire and the remaining tires, youmay have limited four-wheel drivefunctionality.
When driving with the full-size dissimilarspare wheel and tire assembly, it isrecommended that you do not:
•Exceed 50 mph (80 km/h) with a 4WDmode turned on.
•Turn on a 4WD mode unless the vehicleis stationary.
•Use a 4WD mode on dry pavement.
Use of a dissimilar spare wheel and tireassembly may lead to impairment of thefollowing:
•Comfort and noise.
•Winter weather driving capability.
•Wet driving capability.
•Four-wheel drive capability.
How Your Vehicle Differs From OtherVehicles
WARNING: Vehicles with a highercenter of gravity (utility and four-wheeldrive vehicles) handle differently thanvehicles with a lower center of gravity(passenger cars). Avoid sharp turns,excessive speed and abrupt steering inthese vehicles. Failure to drive cautiouslyincreases the risk of losing control of yourvehicle, vehicle rollover, personal injuryand death.

WARNING: You are responsible forcontrolling your vehicle at all times. Thesystem is designed to be an aid and doesnot relieve you of your responsibility todrive with due care and attention. Failureto follow this instruction could result in theloss of control of your vehicle, personalinjury or death.
Active park assist is a multi-step process andmay require you to shift the transmissionmultiple times. Follow the onscreeninstructions until the parking maneuver iscomplete.
If you are uncomfortable with the proximityto any vehicle or object, you may choose tooverride the system by grabbing the steeringwheel, or by taking full control of your vehicleafter pressing the active park assist button.
Keep your hands, hair, clothing and anyloose items clear of the steering wheel whenusing active park assist.
The sensors are on the front and rearbumpers.
Note:Keep the sensors free from snow, iceand large accumulations of dirt.
Note:Do not cover up the sensors.
Note:Do not clean the sensors with sharpobjects.
Note:The sensors may not detect objectswith surfaces that absorb ultrasonic waves.The sensors may falsely detect objects dueto ultrasonic interference caused bymotorcycle exhausts, truck air brakes orhorns, for example.
Note:If you change any tires, the systemmust recalibrate and may not correctlyoperate for a short time.
The system may not correctly operate in anyof the following conditions:
•You use a spare tire or a tire that issignificantly worn more than the othertires.
•One or more tires are incorrectly inflated.
•You try to park on a tight curve.
•Something passes between the frontbumper and the parking space. Forexample, a pedestrian or cyclist.
•The edge of the neighboring parkedvehicle is high off the ground. Forexample, a bus, tow truck or flatbedtruck.
•The weather conditions are poor. Forexample, during heavy rain, snow, fog,high humidity and high temperatures.
Do not use the system if:
•You have attached an add-on accessoryclose to the sensors on the front or rearof your vehicle. For example, a bike rackor trailer.
•You have attached an overhangingobject to the roof. For example, asurfboard.
•The front bumper, rear bumper or theside sensors are damaged.
•The correct tire size is not in use on yourvehicle. For example, a mini-spare tire.

Parking Aids

Your vehicle may be equipped with atemporary or conventional spare tire. Atemporary spare tire is different in size(diameter or width), tread-type (All-Seasonor All-Terrain) or is from a differentmanufacturer than the road tires on yourvehicle. Consult information on the tire labelor Safety Compliance label for limitationswhen using.
Launching or Retrieving a Boat orPersonal Watercraft (PWC)
Note:Disconnect the wiring to the trailerbefore backing the trailer into the water.
Note:Reconnect the wiring to the trailerafter removing the trailer from the water.
When backing down a ramp during boatlaunching or retrieval:
•Do not allow the static water level to riseabove the bottom edge of the rearbumper.
•Do not allow waves to break higher than6 in (15 cm) above the bottom edge ofthe rear bumper.
Exceeding these limits may allow water toenter vehicle components:
•Causing internal damage to thecomponents.
•Affecting driveability, emissions, andreliability.
Replace the rear axle lubricant anytime therear axle has been submerged in water.Water may have contaminated the rear axlelubricant, which is not normally checked orchanged unless a leak is suspected or otheraxle repair is required.
TOWING THE VEHICLE ON FOUR
WHEELS
WARNING: If your vehicle has asteering wheel lock make sure the ignitionis in the accessory or on position whenbeing towed.
Recreational Towing
Note:Put your climate control system inrecirculated air mode to prevent exhaustfumes from entering your vehicle. SeeClimate Control (page 151).
Follow these guidelines if you have a needfor recreational towing, such as towing yourvehicle behind a motorhome. Theseguidelines are designed to prevent damageto your transmission.
Two-wheel Drive Vehicles
You cannot tow a two-wheel drive vehiclewith any wheels on the ground as vehicle ortransmission damage may occur. You musttow your vehicle with all four wheels off theground, for example when using acar-hauling trailer.

GENERAL INFORMATION
Use only approved wheel and tire sizes,using other sizes could damage your vehicle.If you change the diameter of the tires fromthat fitted at the factory, the speedometermay not display the correct speed. If youintend to change the size of the wheels fromthat fitted by the manufacturer, you cancheck the suitability with an authorizeddealer.
Additional information related to thefunctionality and maintenance of your tirescan be found later in this chapter. See TireCare (page 394).
You can find the recommended tire inflationpressures can on the Tire Label, which is onthe B-pillar or the edge of the driver door.You can also find this information on theSafety Compliance Certification Label, affixedto either the door hinge pillar, door-latchpost, or the door edge that meets the doorlatch post; next to the driver seating position.
We strongly recommend maintaining thesetire pressures at all times. Failure to followthe tire pressure recommendations cancause uneven treadwear patterns, reducedfuel economy, and adversely affect the wayyour vehicle handles.
Note:Check and set the tire pressure at theambient temperature in which you areintending to drive your vehicle and when thetires are cold.
Note:Check your tire pressures at least onceper month.
If your vehicle has a spare tire, set thepressure to the highest value given for yourvehicle and tire size combination.
Notice to utility vehicle and truckowners
WARNING: Utility vehicles have asignificantly higher rollover rate than othertypes of vehicles.
WARNING: Vehicles with a highercenter of gravity (utility and four-wheeldrive vehicles) handle differently thanvehicles with a lower center of gravity(passenger cars). Avoid sharp turns,excessive speed and abrupt steering inthese vehicles. Failure to drive cautiouslyincreases the risk of losing control of yourvehicle, vehicle rollover, personal injuryand death.
WARNING: In a rollover crash, anunbelted person is significantly more likelyto die than a person wearing a seatbelt.
WARNING: Do not becomeoverconfident in the ability of four-wheeldrive vehicles. Although a four-wheel drivevehicle may accelerate better than atwo-wheel drive vehicle in low tractionsituations, it won't stop any faster thantwo-wheel drive vehicles. Always drive ata safe speed.

Utility vehicles and trucks handle differentlythan passenger cars in the various drivingconditions that are encountered on streets,highways and off-road. Utility vehicles andtrucks are not designed for cornering atspeeds as high as passenger cars any morethan low-slung sports cars are designed toperform satisfactorily under off-roadconditions.
Study your owner's manual and anysupplements for specific information aboutequipment features, instructions for safedriving and additional precautions to reducethe risk of an accident or serious injury.
Four-wheel drive system (If Equipped)
WARNING: Do not becomeoverconfident in the ability of four-wheeldrive vehicles. Although a four-wheel drivevehicle may accelerate better than atwo-wheel drive vehicle in low tractionsituations, it won't stop any faster thantwo-wheel drive vehicles. Always drive ata safe speed.
A vehicle equipped with four-wheel drive,when selected, has the ability to use all fourwheels to power itself. This increases tractionwhich may enable you to safely drive overterrain and road conditions that aconventional two-wheel drive vehicle cannot.
Power is supplied to all four wheels througha transfer case or power transfer unit.Four-wheel drive vehicles allow you to selectdifferent modes as necessary. Forinformation on transfer case operation andshifting procedures, See Four-Wheel Drive(page 216). For information on transfer casemaintenance, See Maintenance (page 361).You should become thoroughly familiar withthis information before you operate yourvehicle.
On some four-wheel drive vehicles, the initialshift from two-wheel to four-wheel drivewhen the vehicle is moving can cause amomentary clunk and ratcheting sound.These sounds are normal and are not causefor concern.
In four-wheel drive vehicles, the size of thespare tire relative to the remaining tires canhave an effect on the 4x4 system. If there isa significant difference between the size ofa spare and the remaining tires, four-wheeldrive functionality may be limited. See UsingFour-Wheel Drive (page 216).
How your vehicle differs from othervehicles
Sport utility vehicles and trucks can differfrom some other vehicles in a few noticeableways. Your vehicle may be:
393
Navigator (TB9) Canada/United States of America, enUSA, Edition date: 201708, Third-Printing-
Wheels and Tires

•Higher - to allow higher load carryingcapacity and to allow it to travel overrough terrain without getting hung up ordamaging underbody components.
•Shorter - to give it the capability toapproach inclines and drive over thecrest of a hill without getting hung up ordamaging underbody components. Allother things held equal, a shorterwheelbase may make your vehiclequicker to respond to steering inputsthan a vehicle with a longer wheelbase.
•Narrower - to provide greatermaneuverability in tight spaces,particularly in off-road use.
As a result of the above dimensionaldifferences, Sport utility vehicles and trucksoften have a higher center of gravity and agreater difference in center of gravitybetween the loaded and unloaded condition.These differences that make your vehicle soversatile also make it handle differently thanan ordinary passenger car.
TIRE CARE
Information About Uniform Tire QualityGrading
Tire Quality Grades apply to newpneumatic passenger car tires. TheQuality grades can be found whereapplicable on the tire sidewall betweentread shoulder and maximum sectionwidth. For example: Treadwear 200Traction AA Temperature A.
These Tire Quality Grades aredetermined by standards that the UnitedStates Department of Transportation hasset.
Tire Quality Grades apply to newpneumatic passenger car tires. They donot apply to deep tread, winter-typesnow tires, space-saver or temporaryuse spare tires, light truck or LT typetires, tires with nominal rim diameters of10 to 12 inches or limited production tiresas defined in Title 49 Code of FederalRegulations Part 575.104 (c)(2).
U.S. Department of Transportation Tirequality grades: The U.S. Department ofTransportation requires us to give youthe following information about tiregrades exactly as the government has
written it.

A. T: Indicates a type of tire, designatedby the Tire and Rim Association, that isintended for temporary service on cars,sport utility vehicles, minivans and lighttrucks.
B. 145: Indicates the nominal width ofthe tire in millimeters from sidewall edgeto sidewall edge. In general, the largerthe number, the wider the tire.
C. 80: Indicates the aspect ratio whichgives the tire's ratio of height to width.Numbers of 70 or lower indicate a shortsidewall.
D. D: Indicates a diagonal type tire.
R: Indicates a radial type tire.
E. 16: Indicates the wheel or rimdiameter in inches. If you change your
wheel size, you will have to purchasenew tires to match the new wheeldiameter.
Location of the Tire Label
You will find a Tire Label containing tireinflation pressure by tire size and otherimportant information located on theB-Pillar or the edge of the driver's door.See Load Carrying (page 288).
Inflating Your Tires
Safe operation of your vehicle requiresthat your tires are properly inflated.Remember that a tire can lose up to halfof its air pressure without appearing flat.
Every day before you drive, check yourtires. If one looks lower than the others,use a tire gauge to check pressure of alltires and adjust if required.
At least once a month and before long
trips, inspect each tire and check the tirepressure with a tire gauge (includingspare, if equipped). Inflate all tires to theinflation pressure recommended by us.
You are strongly urged to buy a reliabletire pressure gauge, as automaticservice station gauges may beinaccurate. We recommend the use ofa digital or dial-type tire pressure gaugerather than a stick-type tire pressuregauge.
Use the recommended cold inflationpressure for optimum tire performanceand wear. Under-inflation orover-inflation may cause uneventreadwear patterns.
WARNING: Under-inflation is themost common cause of tire failuresand may result in severe tire cracking,tread separation or blowout, withunexpected loss of vehicle control andincreased risk of injury. Under-inflationincreases sidewall flexing and rollingresistance, resulting in heat buildup

Wheels and Tires

Note:If you are checking tire pressurewhen the tire is hot, (for example, drivenmore than 1 mile [1.6 kilometers]), neverbleed or reduce air pressure. The tiresare hot from driving and it is normal forpressures to increase aboverecommended cold pressures. A hot tireat or below recommended cold inflationpressure could be significantlyunder-inflated.
Note:If you have to drive a distance toget air for your tire(s), check and recordthe tire pressure first and add theappropriate air pressure when you getto the pump. It is normal for tires to heatup and the air pressure inside to go upas you drive.
2. Remove the cap from the valve on
one tire, then firmly press the tire gaugeonto the valve and measure thepressure.
3. Add enough air to reach therecommended air pressure.
Note:If you overfill the tire, release airby pressing on the metal stem in thecenter of the valve. Then recheck thepressure with your tire gauge.
4. Replace the valve cap.
5. Repeat this procedure for each tire,including the spare.
Note:Some spare tires operate at ahigher inflation pressure than the othertires. For T type mini-spare tires, see theDissimilar spare wheel and tireassembly information for a description.Store and maintain at 60 psi (4.15 bar).For full-size and dissimilar spare tires,see the Dissimilar spare wheel and tireassembly information for a description.Store and maintain at the higher of thefront and rear inflation pressure as
shown on the Safety ComplianceCertification Label or Tire Label.
6. Visually inspect the tires to make surethere are no nails or other objectsembedded that could poke a hole in thetire and cause an air leak.
7. Check the sidewalls to make surethere are no gouges, cuts or bulges.
Inspecting Your Tires and Wheel ValveStems
Periodically inspect the tire treads foruneven or excessive wear and removeobjects such as stones, nails or glassthat may be wedged in the treadgrooves. Check the tire and valve stemsfor holes, cracks, or cuts that may permitair leakage and repair or replace the tireand replace the valve stem. Inspect thetire sidewalls for cracking, cuts, bruisesand other signs of damage or excessivewear. If internal damage to the tire issuspected, have the tire demounted andinspected in case it needs to be repairedor replaced. For your safety, tires that
are damaged or show signs of excessivewear should not be used because theyare more likely to blow out or fail.
