Noise Emissions Warranty,Prohibited Tampering Acts andMaintenance
On January 1, 1978, Federal regulationbecame effective governing the noiseemission on trucks over 10,000 lb(4,536 kg) Gross Vehicle Weight Rating(GVWR). The preceding statementsconcerning prohibited tampering acts andmaintenance, and the noise warrantyfound in the Warranty Guide, areapplicable to complete chassis cabs over10,000 lb (4,536 kg) GVWR.
CATALYTIC CONVERTER
WARNING: Do not park, idle ordrive your vehicle on dry grass or otherdry ground cover. The emission systemheats up the engine compartment andexhaust system, creating the risk of fire.
WARNING: The normal operatingtemperature of the exhaust system isvery high. Never work around or attemptto repair any part of the exhaust systemuntil it has cooled. Use special care whenworking around the catalytic converter.The catalytic converter heats up to a veryhigh temperature after only a shortperiod of engine operation and stays hotafter the engine is switched off.
WARNING: Exhaust leaks mayresult in entry of harmful and potentiallylethal fumes into the passengercompartment. If you smell exhaustfumes inside your vehicle, have yourvehicle inspected immediately. Do notdrive if you smell exhaust fumes.
Your vehicle has various emission controlcomponents and a catalytic converter thatenables it to comply with applicableexhaust emission standards.
To make sure that the catalytic converterand other emission control componentscontinue to 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 293).
•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.

GENERAL INFORMATION
Note: Occasional brake noise is normal. Ifa metal-to-metal, continuous grinding orcontinuous squeal sound is present, thebrake linings may be worn. Have your vehiclechecked. If the vehicle has continuousvibration or shudder in the steering wheelwhile braking, have your vehicle checked.
Note: Brake dust may accumulate on thewheels, even under normal drivingconditions. Some dust is inevitable as thebrakes wear and does not contribute tobrake noise. Wet brakes result in reducedbraking efficiency. Gently press the brakepedal a few times when driving from a carwash or standing water to dry the brakes.
See Cleaning the Wheels (page 344).
Brake Over Accelerator
In the event the accelerator pedalbecomes stuck or entrapped, apply steadyand firm pressure to the brake pedal toslow the vehicle and reduce engine power.If you experience this condition, apply thebrakes and bring your vehicle to a safestop. Switch the engine off, move thetransmission to park (P) and apply theparking brake. Inspect the acceleratorpedal and the area around it for any itemsor debris that may be obstructing itsmovement. If none are found and thecondition persists, have your vehiclechecked. If your vehicle has to be towed,we recommend that you contact aprofessional towing service.
Emergency Brake Assist
Emergency brake assist detects when youbrake heavily by measuring the rate atwhich you press the brake pedal. Itprovides maximum braking efficiency aslong as you press the pedal. Emergencybrake assist can reduce stopping distancesin critical situations.
Anti-lock Brake System
This system helps you maintain steeringcontrol during emergency stops by keepingthe brakes from locking.
This lamp illuminatesmomentarily when you switchthe ignition on to confirm thelamp is functional.
If the warning lamp does not illuminateduring start up, remains on or flashes, thesystem may be disabled. Have the systemchecked. If the anti-lock brake system isdisabled, normal braking is still operational.
See Warning Lamps and Indicators(page 105).
Note:Indicators vary depending on region.
This lamp illuminatesmomentarily when you switchthe ignition on to confirm thelamp is functional. If it does notilluminate when you switch theignition on, or if it begins to flashat any time except the time during applyingor releasing the parking brake, have thesystem checked.
Regenerative Braking System
This feature simulates the engine brakingof an internal combustion engine andassist the standard brake system whilerecovering some of the energy of motionand storing it in the battery to improve fueleconomy. The standard brake system isdesigned to fully stop the car ifregenerative braking is not available.During regenerative braking, the motor isspun as a generator to create electricalcurrent. This recharges the battery andslows the vehicle. Once the acceleratorpedal is released, the motor changes froman energy user to an energy producer.
