General Safety Guidelines to follow
when working on vehicles
• Always wear approved eye protection.
• Always operate the vehicle in a well ventilated area.
Do not inhale exhaust gases – they are very poisonous!
• Always keep yourself, tools and test equipment away from all
moving or hot engine parts.
• Always make sure the vehicle is in park (Automatic transmis-
sion) or neutral (manual transmission) and that the parking
brake is firmly set. Block the drive wheels.
• Never leave vehicle unattended while running tests.
• Never lay tools on vehicle battery. You may short the terminals
together causing harm to yourself, the tools or the battery.
• Never smoke or have open flames near vehicle.
Vapors from gasoline and charging battery are highly flam-
mable and explosive.
• Always keep a fire extinguisher suitable for gasoline/electrical/
chemical fires handy.
• Always turn ignition key OFF when connecting or disconnect-
ing electrical components, unless otherwise instructed.
• Always follow vehicle manufacturer’s warnings, cautions and
service procedures.
CAUTION:
Some vehicles are equipped with safety air bags.
You must follow vehicle service manual cautions when working
around the air bag components or wiring. If the cautions are not
followed, the air bag may open up unexpectedly, resulting in
personal injury. Note that the air bag can still open up several
minutes after the ignition key is off (or even if the vehicle battery
is disconnected) because of a special energy reserve module.
