Starting and Stopping the Engine

Your vehicle has a fuel and water separatorthat recirculates fuel from the engine tohelp prevent fuel filter clogging. To avoidengine fuel starvation during cold weatheroperation of 32°F (0°C) or below, werecommend that the fuel level in your tankshould not drop below ¼ full. This helpsprevent air from entering the fuel systemand stalling the engine.
Your vehicle has a selective catalyticreduction system that uses Diesel ExhaustFluid (DEF) to operate properly. You needto replenish your vehicle’s DEF at certainintervals. When filling your vehicle’s DEFtank in cold weather, take special care toprevent damage to the tank. SeeSelective Catalytic Reduction System(page 188).
In cold weather below 32°F (0°C), theengine may slowly increase to a higher idlespeed if you leave it idling in park (P). Asthe engine warms-up, the engine soundlevel decreases due to the activation ofPCM-controlled sound reduction features.
If you operate your vehicle in a heavysnowstorm or blowing snow conditions,snow and ice can clog the engine airinduction. If this occurs, the engine mayexperience a significant reduction in poweroutput. At the earliest opportunity, clearall the snow and ice away from inside theair filter assembly. Remove the air cleanercover and the air filter and remove anysnow or ice. Remove any debris, snow orice, on the foam filter by brushing thesurface with a soft brush. Once you havecleared all of the debris, reinstall the airfilter and cover.
Do not use water, solvents, or a hard brushfor cleaning the foam filter.
WARNING
To reduce the risk of vehicle damageand personal burn injuries, do notstart your engine with the air cleanerremoved and do not remove it while theengine is running.
In order to operate the engine intemperatures of 32°F (0°C) or lower, readthe following instructions:
•Make sure that the batteries are ofsufficient size and are fully charged.Check other electrical components tomake sure they are in optimumcondition.
•Use the proper coolant solution at theconcentration recommendedprotecting the engine against damagefrom freezing.
•Try to keep the fuel tank full as muchas possible at the end of operation toprevent condensation in the fuelsystem.
•Make sure you use proper cold weatherengine oil and that it is at its properlevel. Also, if necessary, make sure tofollow the engine oil and filter changeschedule found under the Specialoperating conditions section listed inthe scheduled maintenanceinformation.
•At temperatures of -9°F (-23°C) orbelow, it is recommended that you usean engine block heater to improve coldengine starting.

present, 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. No additional vehicleservice is required.
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 (bulb is burned out),or if the OBD-II system has determinedthat some of the emission control systemshave not been properly checked. In thiscase, the vehicle is not ready for I/Mtesting.
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 thevehicle is not ready for I/M testing. Todetermine if the vehicle is ready for I/Mtesting, turn the ignition key to the on
position 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.
