Starting and Stopping the Engine

If your vehicle runs out of fuel:
•Add a minimum of 1.3 gal (5 L) of fuel torestart the engine.
•You may need to switch the ignition fromoff to on several times after refueling toallow the fuel system to pump the fuelfrom the tank to the engine. Whenrestarting, cranking time takes a fewseconds longer than normal.
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 pump nozzlecan produce static electricity. This cancause a fire if you are filling an ungroundedfuel container.
Use the following guidelines to avoidelectrostatic charge build-up, which canproduce a spark, when filling an ungroundedfuel container:
•Only use an approved fuel container totransfer fuel to your vehicle. Place thecontainer on the ground when filling it.
•Do not fill a fuel container when it isinside your vehicle (including the cargoarea).
•Keep the fuel pump nozzle in contactwith the fuel container when filling it.
•Do not use a device that holds the fuelpump nozzle lever in the fill position.
Adding Fuel From a Portable FuelContainer
WARNINGS
Do not insert the nozzle of a fuelcontainer or an aftermarket funnel intothe fuel filler neck. This may damage the fuelsystem filler neck or its seal and cause fuelto run onto the ground.
WARNINGS
Do not try to pry open or push openthe capless fuel system with foreignobjects. This could damage the fuel systemand its seal and cause injury to you or others.
Do not dispose of fuel in the householdrefuse or the public sewage system.Use an authorized waste disposal facility.
When refueling the vehicle fuel tank from afuel container, use the fuel filler funnelincluded with your vehicle. See Fuel FillerFunnel Location (page 169).
Note:Do not use aftermarket funnels as theymay not work with the capless fuel systemand can damage it.
When refueling the vehicle fuel tank from afuel container, do the following:

FUEL CONSUMPTION
The advertised capacity is the maximumamount of fuel that you can add to the fueltank after running out of fuel. Included in theadvertised capacity is an empty reserve. Theempty reserve is an unspecified amount offuel that remains in the fuel tank when thefuel gauge indicates 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 tank is 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 is yourengine’s break-in period). A more accuratemeasurement is obtained after 2,000 mi(3,200 km) to 3,000 mi (4,800 km). Also, fuelexpense, frequency of fill ups or fuel gaugereadings are not accurate ways to measurefuel economy.
1. Fill the fuel tank completely and recordthe initial odometer reading.
2.Each time you fill the fuel tank, record theamount 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 per gallon)fuel consumption, divide miles traveled bygallons 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 current drivingconditions. Keeping records during summerand winter will show how temperatureimpacts fuel economy.

Fuel and Refueling

•An open or pinched sensor hose.
•Incorrect engine oil level.
•Incorrect fuel for climatic conditions.
•Incorrect engine oil viscosity for climacticconditions.
Note:Some vehicles have a lifetime fuel filterthat is integrated with the fuel tank. Regularmaintenance or replacement is not needed.
Note:If these checks do not help you correctthe concern, have your vehicle checked assoon as possible.

CATALYTIC CONVERTER
WARNINGS
Do not park, idle or drive your vehicleon dry grass or other dry ground cover.The emission system heats up the enginecompartment and exhaust system, creatingthe risk of fire.
The normal operating temperature ofthe exhaust system is very high. Neverwork around or attempt to repair any part ofthe exhaust system until it has cooled. Usespecial care when working around thecatalytic converter. The catalytic converterheats up to a very high temperature afteronly a short period of engine operation andstays hot after the engine is switched off.
Exhaust leaks may result in entry ofharmful and potentially lethal fumesinto the passenger compartment. If you smellexhaust fumes inside your vehicle, have yourvehicle inspected immediately. Do not driveif you smell exhaust fumes.
Your vehicle has various emission controlcomponents and a catalytic converter thatenables it to comply with applicable exhaustemission standards.
To make sure that the catalytic converter andother emission control components continueto 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 268).
•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.

Engine Emission Control

If the service engine soon indicator remainson, have your vehicle serviced at the firstavailable opportunity. Although somemalfunctions detected by the OBD-II may nothave symptoms that are apparent, continueddriving with the service engine soon indicatoron can result in increased emissions, lowerfuel economy, reduced engine andtransmission smoothness and lead to morecostly repairs.
Readiness for Inspection andMaintenance (I/M) Testing
Some state and provincial and localgovernments may haveInspection/Maintenance (I/M) programs toinspect the emission control equipment onyour vehicle. Failure to pass this inspectioncould prevent you from getting a vehicleregistration.
If the service engine soon indicatoris on or the bulb does not work,your vehicle may need service.See On-Board Diagnostics.
Your vehicle may not pass the I/M test if theservice engine soon indicator is on or notworking properly (bulb is burned out), or ifthe OBD-II system has determined that someof the emission control systems have notbeen properly checked. In this case, thevehicle is not ready for I/M testing.
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 the vehicleis not ready for I/M testing. To determine ifthe vehicle is ready for I/M testing, turn theignition key to the on position for 15 secondswithout cranking the engine. If the serviceengine soon indicator blinks eight times, itmeans that the vehicle is not ready for I/Mtesting; if the service engine soon indicatorstays on solid, it means that your vehicle isready for 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, youcan perform the following driving cycleconsisting of mixed city and highway driving:
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 least eighthours with the ignition off. Then, start thevehicle and complete the above drivingcycle. The vehicle must warm up to itsnormal operating temperature. Oncestarted, do not turn off the vehicle untilthe above driving cycle is complete.
If the vehicle is still not ready for I/M testing,you need to repeat the above driving cycle.
