REFUELING
WARNINGS
Fuel vapor burns violently and a fuelfire can cause severe injuries.
Read and follow all the instructionson the pump island.
WARNINGS
When refueling always shut theengine off and never allow sparks oropen flames near the fuel tank fillervalve. Never smoke or use a cell phonewhile refueling. Fuel vapor is extremelyhazardous under certain conditions. Avoidinhaling excess fumes.
Stay outside your vehicle and do notleave the fuel pump unattendedwhen refueling your vehicle.
Keep children away from the fuelpump. Never let children pump fuel.
Wait at least 10 seconds beforeremoving the fuel pump nozzle toallow any residual fuel to drain intothe fuel tank.
Stop refueling after the fuel pumpnozzle automatically shuts off for thesecond time. Failure to follow thiswill fill the expansion space in the fuel tankand could lead to fuel overflowing.
Do not remove the fuel pump nozzlefrom its fully inserted position whenrefueling.
The fuel system may be underpressure. If you hear a hissing soundnear the fuel filler inlet, do not refueluntil the sound stops. Otherwise, fuel mayspray out, which could cause seriouspersonal injury.
Easy Fuel™ Capless System
Your vehicle has an auto-sealing featurethat locks the fuel tank refueling valve andthe fuel filler door. Before you can refuelyour vehicle, you must press the fuel fillerdoor release button on the instrumentpanel. Pressing the button unlocks the fueltank refueling valve and opens the fuelfiller door.

4. Pull the manual fuel filler door releaselever.
5. Switch the ignition off and refuel yourvehicle within 20 minutes. If more than20 minutes is required, fully close thefuel filler door and repeat theprocedure.
FUEL CONSUMPTION
The advertised capacity is the maximumamount of fuel that you can add to the fueltank after running out of fuel. Included inthe advertised capacity is an emptyreserve. The empty reserve is anunspecified amount of fuel that remainsin the fuel tank when the fuel gaugeindicates empty.
Note:The amount of fuel in the emptyreserve varies and should not be relied uponto increase driving range.
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
Do not measure fuel economy during thefirst 1,000 mi (1,600 km) of driving (this isyour engine’s break-in period). A moreaccurate measurement is obtained after2,000 mi (3,200 km) to 3,000 mi(4,800 km). Also, fuel expense, frequencyof fill ups or fuel gauge readings are notaccurate ways to measure fuel economy.
1.Fill the fuel tank completely 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 (city or highway).This provides an accurate estimate of yourvehicle's fuel economy under currentdriving conditions. Keeping records duringsummer and winter will show howtemperature impacts fuel economy.
Conditions
•Heavily loading your vehicle reducesfuel economy.
•Carrying unnecessary weight in yourvehicle may reduce fuel economy.
•Adding certain accessories to yourvehicle such as bug deflectors, rollbarsor light bars, running boards and skiracks may reduce fuel economy.
•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.

BREAKING-IN
You need to break in new tires forapproximately 300 mi (480 km). Duringthis time, your vehicle may exhibit someunusual driving characteristics. The enginealso needs to break in. Avoid hardaccelerations and driving too fast for thefirst 1,000 mi (1,600 km). If possible, avoidcarrying heavy loads up steep gradesduring the break-in period.
ECONOMICAL DRIVING
Your fuel economy depends on:
•How you drive your vehicle.
•How you maintain your vehicle.
•The conditions you drive your vehiclein.
You may improve your fuel economy bykeeping these in mind:
•Drive your vehicle at reasonablespeeds. Traveling at 65 mph(105 km/h) uses about 15% less fuelthan traveling at 75 mph (121 km/h).
•Drive at steady speeds withoutstopping.
•Anticipate stops. Slowing down yourvehicle may eliminate the need to stop.
•Keep the tires properly inflated and useonly the recommended size.
•Switch off the heater if you do not needit. When you have the heater on, keepit at the lowest blower andtemperature setting necessary to becomfortable.
•When it is cold outside, park in a sunnylocation or a climate-controlledenvironment. This may save fuel byreducing the energy needed to heat thecabin.
•Switch off the air conditioning if you donot need it. When you have the airconditioning on, keep it at the lowestblower and highest temperaturesetting necessary to be comfortable.
•When it is hot or sunny outside, parkingin a shaded or climate-controlledenvironment will save fuel by reducingthe energy needed to cool the cabin.
•For Plug-In Hybrid vehicles, usepreconditioning to improve your fueleconomy. See High Voltage Battery(page 151).
•Switch off the heated seats if you arenot using them.
•Switch off the defroster when you nolonger need it for visibility.
•For Plug-In Hybrid vehicles, plug in andrecharge the high voltage batterywhenever possible.
•Use ECO Cruise Control, especially inhilly terrain. See Cruise Control (page177).
•Shift into low gear (L) when enhancedengine braking is needed. Otherwise,use drive gear (D) shift position.
•Combine errands and minimizestop-and-go driving. A warmed upengine works more efficiently. Whenrunning errands, go to the farthestdestination first and then work yourway back home.
•Close the windows for high-speeddriving.
•Use the recommended engine oil. SeeCapacities and Specifications (page282).
•Perform all regularly scheduledmaintenance. See ScheduledMaintenance (page 441).
•Use the coach and brake coach displayto get feedback on your economicaldrive style. See Information Displays(page 92).

Low Engine Use (If Equipped)
The low engine use mode is equipped onEnergi models only. The low engine usemode keeps the engine oil quality in goodcondition when you drive your vehicle withlimited engine use. If your vehicle is in lowengine use mode when you start thevehicle, a message appears in theinformation display. When your vehicle isin low engine use mode, your vehicle runsthe engine as necessary.
Selecting EV Now mode when your vehicleis in the low engine use mode suspendsthe low engine use mode for as long as youcontinue driving your vehicle. The lowengine use mode resumes the next timeyou start your vehicle.
Changing the engine oil and resetting theoil life monitoring system suspends the lowengine use mode.
Operating in Cold Climates andShort Driving Cycles
Some gasoline engines may experience abuildup of moisture in the engine oil ifrepeatedly operated in cold weather andshort driving cycles that do not fully warmthe engine.
When you see a thick milky substanceunder the oil cap, this indicates moistureis present.
This condition can be more prevalent ingas electric hybrid vehicles that run the gasengine for very short driving cycles.
To prevent engine damage under theseconditions customers should follow thesesteps:
•Drive your vehicle at full enginetemperature for 15 to 30 minutes.
•Drive your vehicle at highway speeds.
•Drive your vehicle with the defroster(hybrid vehicles) at full.
We recommend frequent oil changes.Follow severe duty cycle in themaintenance guide. This helps remove themoisture contaminated oil from the engine.
Cold Weather Operation
To determine if the shortened oil changeinterval or warming of the engine issufficient, clean and check the oil fill capon a regular basis. This will confirm thatthe thick milky substance is not returning.
When extreme cold weather and sub-zeroconditions exist, fuel may be found in theengine oil. This is caused by the engine notreaching its full engine temperature.
In this situation, carry out the above stepsto prevent engine damage.
