Safety Information
For your own safety and the safety of others, and to prevent damage to the device
and vehicles upon which it is used, it is important that the safety instructions
presented throughout this manual be read and understood by all persons operating
or coming into contact with the device.
There are various procedures, techniques, tools, and parts for servicing vehicles,
as well as in the skill of the person doing the work. Because of the vast number of
test applications and variations in the products that can be tested with this
equipment, we cannot possibly anticipate or provide advice or safety messages to
cover every circumstance. It is the automotive technician’s responsibility to be
knowledgeable of the system being tested. It is crucial to use proper service
methods and test procedures. It is essential to perform tests in an appropriate and
acceptable manner that does not endanger your safety, the safety of others in the
work area, the device being used, or the vehicle being tested.
Before using the device, always refer to and follow the safety messages and
applicable test procedures provided by the manufacturer of the vehicle or
equipment being tested. Use the device only as described in this manual. Read,
understand, and follow all safety messages and instructions in this manual.
Safety Messages
Safety messages are provided to help prevent personal injury and equipment
damage. All safety messages are introduced by a signal word indicating the hazard
level.
DANGER
Indicates an imminently hazardous situation which, if not avoided, will result in
death or serious injury to the operator or to bystanders.
WARNING
Indicates a potentially hazardous situation which, if not avoided, could result in
death or serious injury to the operator or to bystanders.
Safety Instructions
The safety messages herein cover situations Autel is aware of. Autel cannot know,
evaluate or advise you as to all of the possible hazards. You must be certain that
any condition or service procedure encountered does not jeopardize your personal
safety.

iii
DANGER
When an engine is operating, keep the service area WELL VENTILATED or attach
a building exhaust removal system to the engineexhaust system. Enginesproduce
carbon monoxide, an odorless, poisonous gas that causes slower reaction time and
can lead to serious personal injury or loss of life.
SAFETY WARNINGS
Always perform automotive testing in a safe environment.
Wear safety eye protection that meets ANSI standards.
Keep clothing, hair, hands, tools, test equipment, etc. away from all moving or
hot engine parts.
Operate the vehicle in a well-ventilated work area, for exhaust gases are
poisonous.
Put the transmission in PARK (for automatic transmission) or NEUTRAL (for
manual transmission) and make sure the parking brake is engaged.
Put blocks in front of the drive wheels and never leave the vehicle unattended
while testing.
Be extra cautious when working around the ignition coil, distributor cap, ignition
wires and spark plugs. These components create hazardous voltages when
the engine is running.
Keep a fire extinguisher suitable for gasoline, chemical, and electrical fires
nearby.
Do not connect or disconnect any test equipment while the ignition is on or the
engine is running.
Keep the test equipment dry, clean, free from oil, water or grease. Use a mild
detergent on a clean cloth to clean the outside of the equipment as necessary.
Do not drive the vehicle and operate the test equipment at the same time. Any
distraction may cause an accident.
Refer to the service manual for the vehicle being serviced and adhere to all
diagnostic procedures and precautions. Failure to do so may result in personal
injury or damage to the test equipment.
To avoid damaging the test equipment or generating false data, make sure the
vehicle battery is fully charged and the connection to the vehicle DLC is clean
and secure.
Do not place the test equipment on the distributor of the vehicle. Strong electro-
magnetic interference can damage the equipment.
