Vehicles With A High Voltage System (Hybrid Vehicles)
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.
-- Turn 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.
For all procedures on vehicles with high-voltage system pay attention to the additional warning message for these vehicles. Refer to WARNINGS WHEN WORKING ON VEHICLES WITH HIGH VOLTAGE SYSTEM .
If procedures are necessary near components of the high-voltage system "perform a visual inspection of the damage of the high-voltage components and lines". Refer to PERFORMING A VISUAL INSPECTION OF DAMAGE TO HIGH VOLTAGE COMPONENTS AND CABLES .
If work on the components of the high-voltage system is necessity, de-energize the high-voltage system. Refer to the appropriate service information. .
Vehicles with Start/Stop System
There is a Risk of Injury from the Engine Starting Unexpectedly
The engine can start unexpectedly on vehicles with an activated Start/Stop System. A message appears in the instrument cluster indicating whether the Start/Stop System is activated.
-- Deactivate the Start/Stop System: Turn off the ignition.
