Preparing the vehicle for working in the engine compartment
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Checklist
The following steps should always be carried out in the specified order before working in the
engine compartment ⇒:
There are rotating components in the engine compartment that can cause serious injury.
•Never place your hand near or directly in the radiator fan. Touching the rotary blades can
result in serious injuries. The fan is temperature-controlled and can start automatically,
even if the engine has been switched off and the vehicle key has been removed from the
ignition lock.
•If any work has to be performed when the engine is started or with the engine running,
there is an additional, potentially fatal, safety risk from the rotating parts, such as the drive
belts, alternator, radiator fan, etc., and from the high-voltage ignition system. Always be
particularly careful.
- Always ensure that no body parts, jewellery, ties, loose items of clothing or long hair
can be caught up in rotating engine components. Before starting work, remove any
jewellery and ties, tie up long hair and pull clothes in tightly to avoid them getting
caught in the engine compartment.
- Always depress the accelerator carefully and never without due consideration. The
vehicle can start to move even if the handbrake is applied.
•Always ensure that you have not left any objects, such as cleaning cloths and tools, in the
engine compartment. Any forgotten items can cause malfunctions, engine damage and
fires.
WARNING
Operating fluids and some materials in the engine compartment are highly flammable and can
cause fires and serious injuries!
•Never smoke while working on the vehicle.
•Never work near naked flames or sparks.
•Never spill fluids onto the engine. They could ignite on hot engine components and hence
cause injuries.
•Please note the following when carrying out any work on the fuel system or the electrical
system:
- Always disconnect the vehicle battery.
- Never work in the direct proximity of heating systems, water heaters or any other
open flames.
•Always have a fully functional and tested fire extinguisher to hand.
WARNING
When refilling or changing operating fluids please ensure that the fluids are in the correct
container. Incorrect operating fluids can cause serious functional problems and engine
damage.
