Engine Oil Pressure Gauge
Indicates engine oil pressure. The needleshould stay in the normal operating range(between L and H). If the needle fallsbelow the normal range, stop your vehicle,turn off the engine and check the engineoil level. Add oil if needed. If the oil level iscorrect, have your vehicle checked by anauthorized dealer.
Engine Coolant TemperatureGauge
WARNING
Never remove the coolant reservoircap when the engine is running orhot.
Indicates engine coolant temperature. Atnormal operating temperature, the levelindicator will be in the normal range. If theengine coolant temperature exceeds thenormal range, stop your vehicle as soon assafely possible, switch off the engine andlet the engine cool.
Fuel Gauge
Note:The fuel gauge may vary slightlywhen your vehicle is moving or on a gradient.
Switch the ignition on. The fuel gauge willindicate approximately how much fuel isleft in the fuel tank. The arrow adjacent tothe fuel pump symbol indicates on whichside of your vehicle the fuel filler door islocated.
The needle should move toward F whenyou refuel your vehicle. If the needle pointsto E after adding fuel, this indicates yourvehicle needs service soon.
After refueling some variability in needleposition is normal:
•It may take a short time for the needleto reach F after leaving the gas station.This is normal and depends upon theslope of pavement at the gas station.
•The fuel amount dispensed into thetank is a little less or more than thegauge indicated. This is normal anddepends upon the slope of pavementat the gas station.
•If the gas station nozzle shuts offbefore the tank is full, try a differentgas pump nozzle.
Low Fuel Reminder
A low fuel reminder triggers when thedistance to empty value reaches 50 mi(80 km) to empty, with additionalwarnings at 25 mi (40 km), 10 mi (20 km)and 0 mi (0 km) to empty, provided themessage is cleared each time. Anadditional warning at 75 mi (120 km) toempty is provided when the MyKey is beingused.
Variations:
Note:The distance-to-empty warning can appear at different fuel gauge positions dependingon fuel economy conditions. This variation is normal.

Guarding Against Exhaust Fumes
WARNING
Exhaust leaks may result in entry ofharmful and potentially lethal fumesinto the passenger compartment. Ifyou smell exhaust fumes inside yourvehicle, have your vehicle inspectedimmediately. Do not drive if you smellexhaust fumes.
Important Ventilating Information
If you stop your vehicle and then leave theengine idling for long periods of time, werecommend that you do one of thefollowing:
•Open the windows at least 1 inch (2.5centimeters).
•Set your climate control to outside air.
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

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.
•If operating in arctic temperatures of-20°F (-29°C) or lower, consult yourtruck dealer for information aboutspecial cold weather equipment andprecautions.
