DANGER Risk of accident.  Accidents may result if the vehicle starts off unintentionally with the engine running. Risk of injury  as working around the engine during start-up or while running may result in contusions and burns Secure vehicle to prevent it from moving.
Wear closed and snug-fitting work clothes.
Do not grasp hot or rotating parts.		 AS00.00-Z-0005-01A
DANGER Risk of death.  Death may result if contact is made with parts carrying high voltages. Do not touch parts carrying high voltages. Persons who wear electronic implants (e.g. heart pacemakers) must not carry out work on the ignition system. AS15.10-Z-0001-01A
IMPORTANT References to test conditions for engine testing and adjusting work Air conditioning or automatic air conditioning switched off, coolant at correct level, oil in engine at correct level, ATF at correct level and no leaks in automatic transmission (visual inspection), ancillary consumers switched off.
