•An open or pinched sensor hose.
•Incorrect engine oil level.
•Incorrect fuel for climatic conditions.

Noise Emissions Warranty, ProhibitedTampering Acts and Maintenance
On January 1, 1978, Federal regulationbecame effective governing the noiseemission on trucks over 10,000 lb (4,536 kg)Gross Vehicle Weight Rating (GVWR). Thepreceding statements concerning prohibitedtampering acts and maintenance, and thenoise warranty found in the Warranty Guide,are applicable to complete chassis cabs over10,000 lb (4,536 kg) GVWR.
CATALYTIC CONVERTER
WARNING: Do not park, idle or driveyour vehicle on dry grass or other dryground cover. The emission system heatsup the engine compartment and exhaustsystem, creating the risk of fire.
WARNING: The normal operatingtemperature of the exhaust system is veryhigh. Never work around or attempt torepair any part of the exhaust system untilit has cooled. Use special care whenworking around the catalytic converter.The catalytic converter heats up to a veryhigh temperature after only a short periodof engine operation and stays hot after theengine is switched off.
WARNING: Exhaust leaks may resultin entry of harmful and potentially lethalfumes into the passenger compartment. Ifyou smell exhaust fumes inside yourvehicle, have your vehicle inspectedimmediately. Do not drive if you smellexhaust fumes.
Your vehicle has various emission controlcomponents and a catalytic converter thatenables it to comply with applicable exhaustemission standards.
To make sure that the catalytic converter andother emission control components continueto work properly:
•Do not crank the engine for more than10 seconds at a time.
•Do not run the engine with a spark pluglead disconnected.
•Do not push-start or tow-start yourvehicle. Use booster cables. See JumpStarting the Vehicle (page 329).
•Use only the specified fuel listed.
•Do not switch the ignition off when yourvehicle is moving.
•Avoid running out of fuel.
•Have the items listed in scheduledmaintenance information performedaccording to the specified schedule.
Note:Resulting component damage maynot be covered by the vehicle Warranty.

Engine Emission Control

BREAKING-IN
You need to break in new tires forapproximately 300 mi (480 km). During thistime, your vehicle may exhibit some unusualdriving characteristics.
Avoid driving too fast during the first 1,000 mi(1,600 km). Vary your speed frequently andchange up through the gears early. Do notlabor the engine.
Do not tow during the first 1,000 mi(1,600 km).
REDUCED ENGINE PERFORMANCE
WARNING: If you continue to driveyour vehicle when the engine isoverheating, the engine could stop withoutwarning. Failure to follow this instructioncould result in the loss of control of yourvehicle.
If the engine coolant temperature gaugeneedle moves to the upper limit position, theengine is overheating. See Gauges (page112).
You must only drive your vehicle for a shortdistance if the engine overheats. Thedistance you can travel depends on ambienttemperature, vehicle load and terrain. Theengine continues to operate with limitedpower for a short period of time.
If the engine temperature continues to rise,the fuel supply to the engine reduces. Theair conditioning switches off and the enginecooling fan operates continually.
1. Gradually reduce your speed and stopyour vehicle as soon as it is safe to doso.
2. Immediately switch the engine off toprevent severe engine damage.
3. Wait for the engine to cool down.
4. Check the coolant level. See EngineCoolant Check (page 366).
5. Have your vehicle checked as soon aspossible.
ECONOMICAL DRIVING
Fuel economy is affected by several thingssuch as how you drive, the conditions youdrive under and how you maintain yourvehicle.
There are some things to keep in mind thatmay improve your fuel economy:
•Accelerate and slow down in a smooth,moderate fashion.
•Drive at steady speeds.
•Anticipate stops; slowing down mayeliminate the need to stop.
•Combine errands and minimizestop-and-go driving (When runningerrands, go to the furthest destinationfirst and then work your way back home).
•Close the windows for high-speeddriving.
•Drive at reasonable speeds.
•Keep the tires properly inflated and useonly the recommended size.
•Use the recommended engine oil.
•Perform all regularly scheduledmaintenance.

ENGINE OIL CHECK
To check the engine oil level consistentlyand accurately, do the following:
1.Make sure the parking brake is on. Makesure the transmission is in park (P) orneutral (N).
2. Run the engine until it reaches normaloperating temperature.
3. Make sure that your vehicle is on levelground.
4.Switch the engine off and wait 15 minutesfor the oil to drain into the oil pan. Checking the engine oil level too soonafter you switch the engine off may resultin an inaccurate reading.
5. Open the hood. See Opening andClosing the Hood (page 361).
