Safety Precautions When Working On Vehicles With High-Voltage System

Extremely Dangerous Due To High-Voltage.

The high-voltage system is under high-voltage. Death or serious bodily injury by electric shock.

-- Individuals with electronic/medical life- and health sustaining machines in or on their person cannot perform any work on high-voltage systems. Life- and health sustaining machines are for example pain killer pumps, implanted defibrillators, pacemakers, insulin pumps, and hearing aids.

-- Have the high-voltage system de-energized by a qualified person.

There is a risk of injury from the engine starting unexpectedly.

On electric - hybrid vehicles an active ready mode is difficult to identify. Parts of the body can be clamped or pulled.

-- Switch off the ignition.

-- Place the ignition key outside of the vehicle interior.

Risk of damaging the high-voltage cables.

Misuse can damage the insulation of high-voltage cables or high-voltage connectors.

-- Never support objects on the high-voltage cables and the high-voltage connectors.

-- Never support tools on the high-voltage cables and the high-voltage connectors.

-- Never sharply bend or kink the high-voltage cables.

-- When connecting pay attention to the coding of the high-voltage connectors.

There is a risk of injury when the auxiliary climate control is activated.

When the auxiliary climate control is activated on electric and hybrid vehicles, the auxiliary climate control can turn on unintentionally. Parts of the body may be pinched or pulled by automated radiator fans.

-- Deactivate the auxiliary climate control.
