STARTING A GASOLINE
ENGINE
When you start the engine, the idle speedincreases helping to warm up the engine.If the engine idle speed does not slowdown, have your vehicle checked as soonas possible.
Before starting the engine check thefollowing:
•Make sure all occupants fasten theirseatbelts.
•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 pedal.
1.Fully press the brake pedal.
2.Turn the key to the start position tostart the engine. Release the key whenthe engine starts.
Note:The engine may continue crankingfor up to 15 seconds or until it starts.
Note:If you cannot start the engine on thefirst try, wait for a short period and try again.
Failure to Start
If you cannot start the engine after threeattempts, wait 10 seconds and follow thisprocedure:
1.Fully press the brake pedal.
2.Shift into park (P).
3.Fully press and hold the acceleratorpedal.
4.Attempt to start your vehicle and waituntil the engine stops cranking.
5.Release the accelerator pedal.
6.Start the engine.
Stopping the Engine When YourVehicle is Stationary
1.Shift into park (P) or neutral (N).
2.Turn the key to the off position.
3.Apply the parking brake.
Stopping the Engine When YourVehicle is Moving
WARNING: Switching off theengine when your vehicle is still movingresults in a significant decrease inbraking assistance. Higher effort isrequired to apply the brakes and to stopyour vehicle. A significant decrease insteering assistance could also occur. Thesteering does not lock, but higher effortcould be required to steer your vehicle.When you switch the ignition off, someelectrical circuits, for example airbags,also turn off. If you unintentionally switchthe ignition off, shift into neutral (N) andrestart the engine.
1.Switch the ignition off to stop theengine.

2.Put the transmission into neutral (N)and use the brakes to bring your vehicleto a safe stop.
3.When your vehicle has stopped, shiftinto park (P).
4.Apply the parking brake.
Guarding Against Exhaust Fumes
WARNING: Exhaust leaks mayresult in entry of harmful and potentiallylethal fumes into the passengercompartment. If you smell exhaustfumes inside your vehicle, have yourvehicle inspected immediately. Do notdrive if you smell exhaust fumes.
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.
