280Checking and refilling levels
WARNING (Continued)
● Once the engine has cooled, follow the instructions below before
opening the bonnet:
–Turn on the electronic parking brake and place the gear selector
lever in P or the gear stick in neutral.
– Remove the key from the ignition.
– Keep children away from the engine compartment and never leave
them unsupervised.
● When the engine is warm or hot, the cooling system is pressurised.
Do not unscrew the cap on the expansion tank when the engine is hot.
Otherwise, coolant may spray out under pressure causing burns and seri-
ous injury.
–Carefully and slowly unscrew the cap anticlockwise, gently press-
ing down on it.
– Always protect your face, hands and arms from hot coolant and
steam using a large, thick cloth.
● When refilling liquids, avoid spilling them on parts of the engine and
the exhaust system. Spilled liquids could cause a fire.
WARNING
The high voltages of the electrical system can give electric shocks as well
as causing burns and serious injury and possibly even death!
● Never cause short circuits in the electrical system. The battery could
explode.
● To minimise the risk of electric shock and serious consequences
while the engine is running or starting the engine, note the following:
–Never touch the electrical wiring of the ignition system.
– Never touch electric cables or the gas discharge lamps.
WARNING
In the engine compartment, there are rotating parts that could cause se-
rious injury.
● Never place your hands on or near the radiator fan. Touching the rotor
blades could seriously harm you. The ventilator works according to the
engine temperature and could start suddenly even when the ignition is
turned off and the key is removed.
● 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 as well as from the high-voltage ignition system. Always work with
the utmost caution.
–Always make sure that no parts of your body, jewellery, ties, loose
clothing and long hair can be trapped by the rotating parts of the en-
gine. Before any work, remove ties and jewellery ( necklaces, etc), tie
longhair back and tie all items of loose clothing to your body to make
sure that they cannot be trapped by engine components.
– Take extreme caution when operating the accelerator and remain
attentive. The vehicle could move, even with the electronic parking
brake activated.
● Always make sure you have not left any objects, such as cloths or
tools, in the engine compartment. If any object is left in the engine com-
partment, this could cause malfunctions, engine faults and even a fire.
WARNING
Refill liquids and certain materials can catch fire easily in the engine
compartment, causing a fire and serious injury!
● Never smoke.
● Never work close to places exposed to flames or sparks.
