Safety Precautions When Working On Vehicles With An Internal Combustion Engine

There is a risk of poisoning due to the exhaust from the internal combustion engine.

Internal combustion engines release poisonous exhaust gases when running. Injuries to the respiratory tracts and poisoning are possible.

• Only operate the internal combustion engine in closed rooms with an exhaust extracting system turned on.

There is a risk of injury if the internal combustion engine starts unexpectedly.

The engine can start unexpectedly when the Start/Stop System is activated on the vehicle. Risk of pinching and pulling parts of the body.

• Turn off the ignition and all electric equipment.
• Place the vehicle key and other start authorization systems (such as smartphones) outside of the vehicle interior.

There is a risk of injury due to the drive ready mode.

On hybrid vehicles an active drive ready mode is not clearly identifiable. Risk of pinching and pulling parts of the body.

• Turn off the ignition and all electric equipment.
• Place the vehicle key and other start authorization systems (such as smartphones) outside of the vehicle interior.

There is a risk of injury from exhaust system components.

Injuries to hands and other parts of the body are possible due to hot and sharp-edged exhaust system components.

• Allow the exhaust system to cool down.
• Wear safety gloves.

There is a risk of injury due to hot condensation and particles in the exhaust system

There may be hot condensation and/or particles in the exhaust system. Injury to the eyes, skin and respiratory system and poisoning are possible.

• Wear safety gloves.
• Wear protective eyewear.
• Turn on an exhaust extracting system in enclosed spaces.

Health risk due to chemical materials in the exhaust system components.

Damage to health is possible when disassembling exhaust system post-treatment components.

• Do not cut, saw, or open components of the exhaust post-treatment system.

There is a risk of injury from electric shock

With the engine running, the ignition system is under high-voltage. There is a risk of electric shock if touching the ignition system.

• Do not touch ignition wires when the engine is running or turning at cranking speed.

There is a risk of injury due to the reducing agent

There is a risk of eye and skin irritation as well as injuries to the respiratory system and poisoning due to reducing agents.

• Wear protective eyewear.
• Wear safety gloves.
• Use personal protective equipment.
• Turn on an exhaust extracting system in enclosed spaces.
