Important Ventilating Information
If you stop your vehicle and leave theengine idling for long periods of time, werecommend you either open the windowsat least 1 in (3 cm) or set the climatecontrol to outside air.
STARTING A DIESEL ENGINE
Read all starting instructions carefullybefore you start your vehicle.
The 6.7L diesel engine incorporates a delaybetween a crank command and starterengagement to crank the engine. Thisdelay ensures robust starting performancein all environmental conditions includingextreme cold. The crank command isinitiated by the operator by turning theignition key. The delay varies with enginecoolant temperature. There is no delay forhot coolant temperature. The delayincreases at colder coolant temperatures.Maximum delay of 2.5 seconds isexperienced below -13.0°F (-25°C).
Diesel Engine Fast Start Glow PlugSystem
The diesel engine glow system consists of:
•Eight glow plugs, one per cylinder.
•Glow plug control module.
•Engine coolant temperature sensor.
•Barometric pressure sensor.
•Environmental temperature sensor.
The powertrain and glow plug controlmodules electronically control the glowplug system. After you switch the ignitionon, the glow plug control moduleimmediately energizes the glow plugs. Theglow plug control module, using the enginecoolant temperature, barometric pressuresensor and environmental temperaturesensor, determines how long the glowplugs stay energized. The required time forthe glow plugs to be energized decreasesas the coolant temperature, barometricpressure and environmental temperatureincrease.
Before starting the engine, check thefollowing:
•Make sure all occupants fasten theirseatbelt.
•Make sure the headlamps andelectrical accessories are off.
•Make sure the parking brake is on.
•Make sure the transmission is in park(P) or neutral (N).
•Turn the ignition key to the on position.
Note:Do not press the accelerator duringstarting.
1.Fully press the brake pedal.
2.Turn the key to the start position tostart the engine. Release the key whenthe engine starts.

We recommend that you do the followingfor a safe and correct operation:
•Use a 16-gauge outdoor extension cordthat is product certified byUnderwriter’s Laboratory (UL) orCanadian Standards Association(CSA). This extension cord must besuitable for use outdoors, in coldtemperatures, and be clearly markedSuitable for Use with OutdoorAppliances. Do not use an indoorextension cord outdoors. This couldresult in an electric shock or become afire hazard.
•Use as short an extension cord aspossible.
•Do not use multiple extension cords.
•Make sure that when in operation, theextension cord plug and heater cordplug connections are free and clear ofwater. This could cause an electricshock or fire.
•Make sure your vehicle is parked in aclean area, clear of combustibles.
•Make sure the heater, heater cord andextension cord are firmly connected.
•Check for heat anywhere in theelectrical hookup once the system hasbeen operating for approximately 30minutes.
•Make sure the system is unplugged andproperly stowed before starting anddriving your vehicle. Make sure theprotective cover seals the prongs of theblock heater cord plug when not in use.
•Make sure the heater system ischecked for proper operation beforewinter.
Using the Engine Block Heater
Make sure the receptacle terminals areclean and dry prior to use. Clean them witha dry cloth if necessary.
The heater uses 0.4 to 1.0 kilowatt-hoursof energy per hour of use. The system doesnot have a thermostat. It achievesmaximum temperature afterapproximately three hours of operation.Using the heater longer than three hoursdoes not improve system performance andunnecessarily uses electricity.

RUNNING OUT OF FUEL -
DIESEL
Avoid running out of fuel. This allows air toenter the fuel system and may make itdifficult to restart your vehicle.
If your vehicle runs out of fuel:
•Normally adding 4–5 gal (15–19 L) offuel is enough to restart the engine. Ifyour vehicle is out of fuel and on asteep grade, more than 5 gal (19 L)may be required.
•You must purge trapped air from thesystem before restarting the engine.
Purging Air From the System
Switch the ignition on for 30 seconds andthen switch the ignition off. Repeat thisoperation six times in a row to purge anytrapped air from the fuel system.
Any remaining air in the system self-purgeswhen the engine starts. The engine mayrun rough or produce white smoke whenair remains in the fuel system. This isnormal and stops after a short period. Ifthe engine continues to run rough, haveyour vehicle checked as soon as possible.
Starting the Engine
Do not crank the engine for more than 10seconds as starter damage may occur. Ifthe engine fails to start, switch the ignitionoff and wait 30 seconds before crankingthe engine again. See Starting a DieselEngine (page 103).
RUNNING OUT OF FUEL -
GASOLINE
Avoid running out of fuel because thissituation may have an adverse effect onpowertrain components.
If you run out of fuel:
•You may need to switch the ignitionfrom off to on several times afterrefueling to allow the fuel system topump the fuel from the tank to theengine. When restarting, cranking timetakes a few seconds longer thannormal. With keyless ignition, just startthe engine. Crank time will be longerthan usual.
•Normally, adding 1 gal (3.8 L) of fuel isenough to restart the engine. If thevehicle is out of fuel and on a steepgrade, more than 1 gal (3.8 L) may berequired.
•The service engine soon indicator maycome on. See Warning Lamps andIndicators (page 67).
REFUELING - DIESEL
WARNING: Fuel vapor burnsviolently and a fuel fire can cause severeinjuries.
WARNING: Read and follow all theinstructions on the pump island.
WARNING: When refueling alwaysshut the engine off and never allowsparks or open flames near the fuel tankfiller valve. Never smoke or use a cellphone while refueling. Fuel vapor isextremely hazardous under certainconditions. Avoid inhaling excess fumes.
WARNING: Stay outside yourvehicle and do not leave the fuel pumpunattended when refueling your vehicle.
WARNING: Keep children awayfrom the fuel pump. Never let childrenpump fuel.

1.When your vehicle has stopped, shiftinto neutral (N) or park (P).
2.Apply the parking brake and switch theignition off.
3.Turn the fuel filler capcounterclockwise and remove it.
4.Refuel your vehicle as required.
5.Replace the fuel filler cap, turn itclockwise until you feel a strongresistance.
If the fuel cap warning lamp or a warningmessage appears in the instrument cluster,you may not have installed the fuel fillercap correctly.
If the fuel cap warning lamp remains on,at the next opportunity, safely pull off ofthe road, remove the fuel filler cap, alignthe cap properly and reinstall it. The checkfuel cap warning lamp or warning messagemay not reset immediately. It may takeseveral driving cycles for the indicators toturn off. A driving cycle consists of anengine start-up (after four or more hourswith the engine off) followed by normalcity and highway driving.
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.
