The catalytic converter is part of yourvehicle's emissions system and filters harmfulpollutants from the exhaust gas.
CATALYTIC CONVERTER
PRECAUTIONS
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.
To avoid damaging the catalytic converter:
•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 Precautions (page 318).
•Use the correct fuel. See Fuel andRefueling (page 203).

Is brake dust on the wheels normal?
Brake dust could accumulate on thewheels, even under normal drivingconditions. Some dust is inevitable asthe brakes wear and does not contributeto brake noise. See Cleaning Wheels(page 367).
Will wet driving conditions effect mybraking abilities?
Wet brakes result in reduced brakingefficiency. Gently press the brake pedala few times when driving from a carwash or standing water to dry thebrakes.
Is brake noise considered normal?
Occasional brake noise is normal. If ametal-to-metal, continuous grinding orcontinuous squeal sound is present, thebrake linings may be worn-out and anauthorized dealer should check them.If the vehicle has continuous vibrationor shudder in the steering wheel whilebraking, an authorized dealer shouldcheck your vehicle.
When should you replace the brake fluid?
