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 tankis filled.
•Allow no more than one automaticshut-off when refueling.
Results are most accurate when the fillingmethod is consistent.
Calculating Fuel Economy
Your vehicle calculates fuel economyfigures through the trip computer averagefuel function. See Information Displays(page 96).
The first 1,000 mi (1,500 km) of driving isthe break-in period of the engine. A moreaccurate measurement is obtained after2,000 mi (3,000 km).
1.Completely fill the fuel tank and recordthe initial odometer reading.
2.Each time you fill the fuel tank, recordthe amount 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 pergallon) fuel consumption, divide milestraveled by gallons used.
Keep a record for at least one month andrecord the type of driving, for example cityor highway. This provides an accurateestimate of your vehicle’s fuel economyunder current driving conditions. Keepingrecords during summer and winter showshow temperature impacts fuel economy.
Conditions
•Heavily loading your vehicle reducesfuel economy.
•Carrying unnecessary weight in yourvehicle may reduce fuel economy.
•Avoid adding accessories that increaseaerodynamic drag to your vehicle suchas bug deflectors, car top carriers andski or bike racks.
•Using fuel blended with alcohol maylower fuel economy.
•Fuel economy may decrease with lowertemperatures.
•Fuel economy may decrease whendriving short distances.
•You will get better fuel economy whendriving on flat terrain than when drivingon hilly terrain.

Please consult your warranty informationfor complete details.
On-Board Diagnostics (OBD-II)
Your vehicle has a computer known as theon-board diagnostics system (OBD-II) thatmonitors the engine’s emission controlsystem. The system protects theenvironment by making sure that yourvehicle continues to meet governmentemission standards. The OBD-II systemalso assists a service technician in properlyservicing your vehicle.
When the service engine soonindicator illuminates, the OBD-IIsystem has detected amalfunction. Temporary malfunctions maycause the service engine soon indicator toilluminate. Examples are:
1.Your vehicle has run out of fuel—theengine may misfire or run poorly.
2.Poor fuel quality or water in thefuel—the engine may misfire or runpoorly.
3.The fuel fill inlet may not have closedproperly. See Refueling (page 153).
4.Driving through deep water—theelectrical system may be wet.
You can correct these temporarymalfunctions by filling the fuel tank withgood quality fuel, properly closing the fuelfill inlet or letting the electrical system dryout. After three driving cycles without theseor any other temporary malfunctionspresent, the service engine soon indicatorshould stay off the next time you start theengine. A driving cycle consists of a coldengine startup followed by mixed city andhighway driving. You do not requireadditional vehicle service.
If the service engine soon indicator remainson, have your vehicle serviced at the firstavailable opportunity. Although somemalfunctions detected by the OBD-II maynot have symptoms that are apparent,continued driving with the service enginesoon indicator on can result in increasedemissions, lower fuel economy, reducedengine and transmission smoothness andlead to more costly repairs.

Readiness for Inspection andMaintenance (I/M) Testing
Some state and provincial and localgovernments may haveInspection/Maintenance (I/M) programsto inspect the emission control equipmenton your vehicle. Failure to pass thisinspection could prevent you from gettinga vehicle registration.
If the service engine soonindicator is on or the bulb doesnot work, your vehicle may needservice. See On-Board Diagnostics.
Your vehicle may not pass the I/M test ifthe service engine soon indicator is on ornot working properly, for example, the bulbdoes not work, or if the OBD-II system hasdetermined that some of the emissioncontrol systems have not been properlychecked. In this case, the vehicle is notready for I/M testing.
If you have just serviced the vehicle’sengine or transmission or the battery hasrecently run down or you have replaced it,the OBD-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.
If the vehicle is still not ready for I/Mtesting, you need to repeat the abovedriving cycle.

Sport Mode (S)
Switch on sport mode by shifting thetransmission selector lever to sport (S). Insport (S), the transmission selects theoptimum gear for best performance. Thisgear selection is typically lower than thatof drive (D), and the shifts are faster.
Tow Mode
To switch on tow mode, pressthe button on the center consoleuntil tow mode is active. Theindicator light illuminates in the instrumentcluster when the system becomes active.
The tow mode feature:
•Moves upshifts to higher engine speedsto reduce the frequency oftransmission shifting.
•Provides engine braking in all forwardgears, which slows your vehicle andassists you in controlling your vehiclewhen descending a slope.
•Depending on driving conditions andload conditions, may downshift thetransmission, slow your vehicle andcontrol your vehicle speed whendescending a hill, without pressing theaccelerator pedal. The amount ofdownshift braking provided variesbased upon the amount you press thebrake pedal.
The tow mode feature improvestransmission operation when towing atrailer or a heavy load. All transmissiongear ranges are available when using towmode.
To switch off the tow mode feature andreturn to normal driving mode, press thebutton on the center console twice. Theindicator light turns off when the systemturns off. Tow mode also turns off whenyou power down your vehicle.
SelectShift™ AutomaticTransmission
This feature gives you the ability to changegears up or down as desired.
If the engine speed does not exceed themaximum allowable limit, the vehicleallows the downshifts. SelectShiftautomatically downshifts at low enginespeeds to prevent engine stalls.
Note:Engine damage could occur if youmaintain excessive engine revving withoutshifting.
SelectShift does not automatically upshift,even if the engine is approaching the RPMlimit.
For 10 speed transmissions - with thetransmission selector lever in sport (S)position:
•Press the (+) button on thetransmission selector lever to upshift.
•Press the (-) button on thetransmission selector lever todownshift.

Driving in Special Conditions withFour-Wheel Drive
Four-wheel drive vehicles are suitable fordriving on sand, snow, mud and roughroads and have operating characteristicsthat are somewhat different fromconventional vehicles, both on and off thefreeway.
When driving at slow speeds off road underhigh load conditions, use a low gear whenpossible. Low gear operation maximizesthe engine and transmission coolingcapability.
Basic Operating Principles
When driving your vehicle on surfacesmade slippery by loose sand, water, gravel,snow or ice, proceed with care.
Sand
When driving over sand, try to keep all fourwheels on the most solid area of the trail.Shift to a lower gear and drive steadilythrough the terrain. Apply the acceleratorslowly and avoid excessive wheel slip.
Do not drive your vehicle in deep sand foran extended period of time. This can causethe system to overheat.
To resume operation, switch the ignitionoff and allow the system to cool down fora minimum of 15 minutes.
When driving at slow speeds in deep sandunder high outside temperatures, use a lowgear when possible. Low gear operationmaximizes the engine and transmissioncooling capability.
Avoid driving at excessive speeds, thiscauses vehicle momentum to work againstyou and your vehicle could become stuckto the point that you could requireassistance from another vehicle.Remember, you may be able to back outthe way you came if you proceed withcaution.
Mud and Water
Mud
Be cautious of sudden changes in vehiclespeed or direction when you are driving inmud. Even four-wheel drive vehicles canlose traction in slick mud. If your vehicledoes slide, steer in the direction of the slideuntil you regain control of your vehicle.
After driving through mud, clean off residuestuck to rotating driveshafts and tires.Excess mud stuck on tires and rotatingdriveshafts can cause an imbalance thatcould damage drive components.
Water
If you must drive through high water, driveslowly. Water may limit traction or brakecapability.
When driving through water, determine thedepth and avoid water higher than thebottom of the hubs. If the ignition systemgets wet, your vehicle could stall.
Once through water, try the brakes. Wetbrakes do not stop your vehicle aseffectively as dry brakes. Drying improvesby applying light pressure to the brakepedal when slowly moving.
Note:Driving through deep water maydamage the transmission. If you submergethe front or rear axle in water, have the axlelubricant and power transfer unit lubricantchecked, and change if necessary.

“Tread Lightly” is an educational programdesigned to increase public awareness ofland-use regulations and responsibilitiesin our nation's wilderness areas. We jointhe U.S. Forest Service and the Bureau ofLand Management in encouraging you tohelp preserve our national forest and otherpublic and private lands by “treadinglightly.”
Driving on Hilly or Sloping Terrain
Although natural obstacles may make itnecessary to travel diagonally up or downa hill or steep incline, you should drivestraight up or straight down.
Note: Avoid turning on steep slopes or hills.A danger lies in losing traction, slippingsideways and possible vehicle roll over. Donot drive over the crest of a hill withoutseeing what conditions are on the other side.Do not drive in reverse over a hill without theaid of an observer. Whenever driving on ahill, determine beforehand the route youintend to use.
When climbing a steep slope or hill, startin a lower gear rather than downshifting toa lower gear from a higher gear once theascent has started. This reduces strain onthe engine and the possibility of stalling.
If your vehicle stalls, do not try to turnaround because this could cause vehicleroll over. It is better to reverse back to asafe location.
Apply just enough power to the wheels toclimb the hill. Too much power could causethe tires to slip, spin or lose traction,resulting in loss of vehicle control.
Descend a hill in the same gear you woulduse to climb up the hill to avoid excessivebrake application and brake overheating.Do not descend in neutral (N). Move thetransmission selector lever to a lower gear.When descending a steep hill, avoidsudden hard braking as you could losecontrol. Make sure the front wheels areturning so you can steer your vehicle.
If your vehicle has anti-lock brakes, steadilyapply the brakes. Do not pump the brakes.
Driving on Snow and Ice
WARNING: If you are driving inslippery conditions that require tirechains or cables, then it is critical thatyou drive cautiously. Keep speeds down,allow for longer stopping distances andavoid aggressive steering to reduce thechances of a loss of vehicle controlwhich can lead to serious injury or death.If the rear end of your vehicle slides whilecornering, steer in the direction of theslide until you regain control of yourvehicle.
Note:Excessive tire slippage can causetransmission damage
