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
WARNINGS
Do not park, idle or drive your vehicleon dry grass or other dry ground cover.The emission system heats up the enginecompartment and exhaust system, creatingthe risk of fire.
The normal operating temperature ofthe exhaust system is very high. Neverwork around or attempt to repair any part ofthe exhaust system until it has cooled. Usespecial care when working around thecatalytic converter. The catalytic converterheats up to a very high temperature afteronly a short period of engine operation andstays hot after the engine is switched off.
Exhaust leaks may result in entry ofharmful and potentially lethal fumesinto the passenger compartment. If you smellexhaust fumes inside your vehicle, have yourvehicle inspected immediately. Do not driveif you smell exhaust 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 268).
•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.
