Possible hazards 

Risk of accident  from vehicle starting off during starting operation (e.g. when testing compression pressure) as a result of gear engaged  or when engine running, or vehicles with automatic transmission as a result of selector lever position "P" or "N" not engaged  (exception: some vehicles do not have a selector lever position "P"  ).

Injury hazard 

Severe injuries  may be caused by unshielded rotating parts in the area of the running engine.

The heat produced by the running engine can result in severe burns if contact is made with individual, unshielded parts.

First aid measures in the event of burns 

• Do not rub the skin areas affected; flush with plenty of cold water and cover skin with sterile bandages.
• Consult a doctor without delay.

• Before starting the engine, apply parking brake. 
• On models with manual transmission move gearshift lever into Neutral position. 
• On vehicles with automatic transmission move selector lever into position "P" or "N"  (exception: some vehicles do not have a selector lever position "P"  ).
• On models which do not have selector lever position "P", secure selector lever to prevent it from being operated unintentionally. 
• Wear closed and close-fitting work clothes.
• All items of jewelry like chains or rings must be taken off.
• Restrain long hair by wearing an appropriate head cover.
