1-2 General Information
Section 1: General Information
The following list contains some general warnings that you should follow when you work on a
vehicle.
WARNING:
• Always wear safety glasses for eye protection.
• Use safety stands whenever a procedure requires you to be under the vehicle.
• Make sure that the ignition switch is always in the OFF position, unless otherwise
required by the procedure.
• Set the parking brake when working on the vehicle. The gear selector should be set in
PARK unless instructed otherwise for a specific operation. Place wood blocks (4 in x 4 in
or larger) against the front and rear surfaces of the tires to help prevent the vehicle from
moving.
• Operate the engine only in a well-ventilated area to avoid the danger of carbon monoxide
poisoning.
• Keep yourself and your clothing away from moving parts when the engine is running,
especially the drive belts.
• To reduce the risk of serious burns, avoid contact with hot metal parts such as the
radiator, exhaust manifold, tailpipe, catalytic converter and muffler.
• Do not smoke while working on a vehicle.
• To reduce the risk of injury, always remove rings, watches, loose hanging jewelry and
loose clothing before beginning to work on a vehicle.
• When it is necessary to work under the hood, keep hands and other objects clear of the
radiator fan blades.
• Failure to follow these instructions may result in personal injury.
Making Safety Devices and Elements Inoperative
The vehicle contains many safety features required by Federal or Canadian Motor Vehicle Safety
Standards. These features, which include the key-in-ignition chime and brake lights, should never
be disabled or modified.
Section 30122 of 49 USC states that ‘‘A manufacturer, distributor, dealer or motor vehicle repair
business may not knowingly make inoperative any part of a device or element of design installed
on or in a motor vehicle or motor vehicle equipment in compliance with an applicable motor vehicle
safety standard prescribed under this chapter unless the manufacturer, distributor, dealer or repair
business reasonably believes the vehicle or equipment will not be used (except for testing or a
similar purpose during maintenance or repair) when the device or element is inoperative.’’
