GENERAL INFORMATION
WARNINGS
Extended idling at high enginespeeds can produce very hightemperatures in the engine andexhaust system, creating the risk of fire orother damage.
Do not park, idle or drive your vehicleon dry grass or other dry groundcover. The emission system heats upthe engine compartment and exhaustsystem, creating the risk of fire.
Do not start the engine in a closedgarage or in other enclosed areas.Exhaust fumes can be toxic. Alwaysopen the garage door before you start theengine.

If you disconnect the battery, your vehiclemay exhibit some unusual drivingcharacteristics for approximately 5 miles(8 kilometers) after you reconnect it. Thisis because the engine management systemmust realign itself with the engine. You candisregard any unusual drivingcharacteristics during this period.
The powertrain control system meets allCanadian interference-causing equipmentstandard requirements regulating theimpulse electrical field or radio noise.
When you start the engine, avoid pressingthe accelerator pedal before and duringoperation. Only use the accelerator pedalwhen you have difficulty starting theengine.
If your vehicle is operated in a heavy snowstorm or blowing snow conditions, theengine air induction may become partiallyclogged with snow and ice. If this occurs,the engine may experience a significantreduction in power output. At the earliestopportunity, clear all the snow and iceaway from the air induction inlet.

2. Fully press the accelerator pedal andhold it there.
3. Start the engine.
Stopping the Engine When YourVehicle is Stationary
1. When your vehicle has stopped, shiftinto park (P) and switch the ignitionoff.
2. Apply the parking brake.
Stopping the Engine When YourVehicle is Moving
WARNING
Switching off the engine when thevehicle is still moving will result in aloss of brake and steering assistance.The steering will not lock, but higher effortwill be required. When the ignition isswitched off, some electrical circuits,including air bags, warning lamps andindicators may also be off. If the ignitionwas turned off accidentally, you can shiftinto neutral (N) and re-start the engine.

2. When your vehicle has stopped, shiftinto park (P) and switch the ignitionoff.
3. Apply the parking brake.
Cold Weather Starting (FlexibleFuel Vehicles Only)
The starting characteristics of all gradesof E85 ethanol make it unsuitable for usewhen ambient temperatures fall below-0°F (-18°C). Consult your fuel distributorfor the availability of winter grade ethanol.As the outside temperature approachesfreezing, ethanol fuel distributors shouldsupply winter grade ethanol, the same aswith unleaded gasoline.
If summer grade ethanol is used in coldweather conditions, -0°F (-18°C), you mayexperience increased cranking times, roughidle or hesitation until the engine haswarmed up.
You may experience a decrease inperformance when the engine is cold whenoperating on E85 ethanol.
Do not use starting fluid such as ether inthe air intake system. Such fluid couldcause immediate explosive damage to theengine and possible personal injury.
If you should experience cold weatherstarting problems on E85 ethanol, andneither an alternative brand of E85 ethanolnor an engine block heater is available, theaddition of unleaded gasoline to your tankimproves cold starting performance. Yourvehicle is designed to operate on E85ethanol alone, unleaded gasoline alone, orany mixture of the two.
If the Engine Fails to Start Using thePreceding Instructions (Flexible FuelVehicles Only)
1. Press the accelerator pedal downone-third to one-half of its travel, andthen crank the engine.
2. When the engine starts, release thekey, then gradually release theaccelerator pedal as the engine speedincreases. If the engine still does notstart, repeat Step 1.

STARTING A DIESEL ENGINE -
6.7L DIESEL
Read all starting instructions carefullybefore you start your vehicle.
For temperatures below 32°F (0°C), theuse of the correct grade engine oil isessential for proper operation. Refer toengine oil specifications for moreinformation. See Capacities andSpecifications (page 427).
Your vehicle may have a cold weatherstarting strategy that prevents severeengine damage by assisting in enginelubrication warm-up. In extremely coldambient temperatures, this strategyactivates and prevents the acceleratorpedal from being used for 30 seconds afteryou start your vehicle. A message appearsin the information display as your vehiclewarms up. By not allowing the acceleratorpedal to be used, the engine oil is allowedto properly lubricate the bearings
preventing engine damage due to lack ofproper lubrication. After the 30 secondwarm-up period, the accelerator pedal willbe operational again and a messageappears informing you the vehicle is ok todrive.
When you start the engine in extremelycold temperatures -15°F (-26°C), werecommend that you allow the engine toidle for several minutes before you drivethe vehicle.
Before starting the engine check thefollowing:
•Make sure all occupants have fastenedtheir seatbelts.
•Make sure the headlamps andelectrical accessories are off.
•Make sure the parking brake is on.
•Make sure the transmission is in park(P).
Note:Do not press the accelerator duringstarting.
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 uses the enginecoolant temperature, barometric pressuresensor and environmental temperature
