Safety Precautions When Working On Vehicles With High-Voltage System
High voltage is extremely dangerous.
The high-voltage system is under high voltage. Severe bodily injury or death by electrocution or arcing is possible.
-- When working on the high-voltage system, de-energize the high-voltage system.
-- If procedures do not affect the high-voltage system directly, the high-voltage system should still be de-energized in some cases.
-- For known procedures that require the high-voltage system to be de-energized. Refer to the appropriate service information .
-- Have an Audi high-voltage technician or an Audi high-voltage expert de-energize the high-voltage system.
There is a risk of injury from the engine starting unexpectedly.
On electric and hybrid vehicles an active ready mode is difficult to identify. Parts of the body can be pinched or pulled.
-- Switch off the ignition.
-- Place the ignition key outside of the vehicle interior.
Risk of injury due to an activated parking heater and A/C
The parking heater and A/C can switch on unintentionally on electric and hybrid vehicles with an activated parking heater and A/C. Parts of the body can be pinched or pulled by self-actuating radiator fans.
-- Deactivate the parking heater and A/C.
