WARNING
The engine compartment of any motor vehicle is a dangerous area. Serious injuries can be
sustained here.
●
The utmost care and attention must be paid when carrying out any work and you must
follow the general safety rules. Never take any risks.
●
Never perform any work in the engine compartment unless you know exactly how to carry it
out. If you are uncertain of what to do, the work should be carried out by a qualified
workshop. Serious injuries can result from work that has not been carried out properly.
●
●
Never open the bonnet if you see steam or coolant escaping from the engine compartment.
Hot steam or hot coolant can cause serious burns. Always wait until you can no longer see or
hear steam or coolant coming from the engine compartment.
Always allow the electric drive and high-voltage components to cool down before opening
the bonnet.
●
●
Hot electric drive components can burn the skin.
Once the electric drive has cooled down, the following points should be observed before
opening the bonnet:
●
Switch on the electronic parking brake and move the selector lever to position P or move
the gear lever to the neutral position.
●
Switch off the ignition, remove the vehicle key from the ignition lock and keep it in a safe
place far enough away from the vehicle to prevent any risk of the ignition being switched
on accidentally and supplying power to the electrical system.
●
Always keep children away from the engine compartment and never leave unsupervised.
●
●
The cooling system is under pressure when the electric drive is hot. Never open the cap of
the coolant expansion tank when the electric drive is hot. Coolant may spray out and cause
serious burns and other injuries.
●
Slowly and carefully turn the cap on the coolant expansion tank anticlockwise while
exerting gentle downward pressure on the cap.
●
Always protect the face, hands and arms from hot coolant or steam with a large, thick
cloth.
When refilling, do not spill any service fluids on engine components or on the exhaust
system. The spilt service fluids can start a fire.
WARNING
High voltages in the electrical system can cause electric shocks, burns, serious injuries and
death!
●
●
Never short circuit the electric system. The 12-volt vehicle battery could explode.
In order to reduce the risk of a potentially fatal electric shock and serious injuries while the
vehicle's drive system is active or being activated, never touch high-voltage components,
the high-voltage battery or the high-voltage system, in particular orange high-voltage
cables.
WARNING
There are rotating components in the engine compartment that can cause serious injury.
●
Never reach into the radiator fan or into the area of the radiator fan. Touching the rotor
blades can result in serious injuries. The fan is temperature-controlled and can start
automatically, even when the ignition has been switched off or the vehicle key has been
removed from the ignition lock.
●
If any work has to be performed during the start procedure or when the vehicle’s drive
system is activated, the rotating parts (such as the radiator fan etc.) pose an additional
safety risk, and can potentially cause fatal injuries. 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
engine parts.
●
Always take due care and attention when depressing the accelerator. The vehicle could
start moving even if the electronic parking brake is switched on.
●
Always ensure you have not left any objects, such as cleaning cloths and tools, in the engine
compartment. Any forgotten items can cause malfunctions, damage to the electric drive and
fires.
