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 255).
•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.

If you see any corrosion on the battery orterminals, remove the cables from theterminals and clean with a wire brush. Youcan neutralize the acid with a solution ofbaking soda and water.
Because your vehicle’s engine iselectronically-controlled by a computer,some engine control settings are maintainedby power from the battery. Some enginecomputer settings, like the idle trim and fueltrim strategy, optimize the driveability andperformance of the engine. The clock andradio station presets are also maintained inmemory by power from the low-voltagebattery. These settings are erased when atechnician disconnects and connects thelow-voltage battery.
To restore the settings, do the following:
Note:Until you switch the ignition to the onposition, you will receive a message in yourinformation display stating that your vehicleis not in park.
1. Apply the parking brake.
2. Shift into park (P) or neutral (N).
3. Switch off all accessories.
4. Press the brake pedal and start yourvehicle.
5. Run the engine until it reaches normaloperating temperature. While the engineis warming up, complete the following:Reset the clock. See Audio Unit (page365). Reset the power windowsbounce-back feature. See PowerWindows (page 95). Reset the radiostation presets. See Audio Unit (page365).
6. Allow the engine to idle for at least oneminute.
7.Drive the vehicle at least 10 mi (16 km) tocompletely relearn the idle trim and fueltrim strategy.
Note:If you do not allow the engine torelearn the idle and fuel trim strategy, theidle quality of your vehicle may be adverselyaffected until the engine computereventually relearns the idle trim and fuel trimstrategy.
Note:Certain features may not operate ifthe battery monitor system is not reset witha scan tool following a jump start or batteryreplacement. Normal electrical accessoryoperation should resume after your vehicleis left undisturbed for 8 hours.
Make sure that you dispose of old batteriesin an environmentally friendly way. Seekadvice from your local authority aboutrecycling old batteries.
If storing your vehicle for more than 30 dayswithout recharging the battery, werecommend that you disconnect the batterycables to maintain battery charge for quickstarting.
