Operation CHARM: Car repair manuals for everyone.

Customer Safety Information


1. Ignition systems present a shock hazard. Do not touch ignition system parts (spark plug wires, spark plugs etc...) with the engine running.
2. Keep all sparks, lighted matches, and open flames away from the battery. If hydrogen gas escaping from cap vents is ignited, it will ignite gas trapped in the cells and cause the battery to explode.
3. Catalytic converters routinely reach operating temperatures of 650°C (1200°F). Do not park the vehicle over any object or material that could ignite (i.e. dry leaves, cardboard, puddles of oil, or other combustibles). Catalytic converters stay hot for some time after the engine has been shut off.
4. Parts of the exhaust gases (carbon monoxide) are toxic. Do not run the engine in confined areas or breathe concentrated exhaust gases. Breathing exhaust gases may cause loss of consciousness or even death.
5. Repair exhaust system leaks as soon as possible. Hot gases escaping from leaks can ignite flammable materials and may set the vehicle on fire. Also, exhaust entering the passenger compartment may cause symptoms such as throat, sinus and eye irritation, light headedness, headaches, and increased irritability. This is especially hazardous while driving with windows closed.
6. Be alert for fuel odors and excessive tailpipe emission (black smoke etc...). These are problem indicators.
