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.
296Checking and refilling levels
● the idling speed is increased so that the alternator provides more elec-
tricity.
● where necessary, the power of the most powerful consumers is reduced
or even completely disconnected.
● On starting the engine, the power supply from the 12-volt sockets and
the cigarette lighter may be interrupted for a short time.
The on-board management program cannot always prevent the battery from
running flat. For example, if the ignition is left on for a long period with the
engine off or if the side lights or parking lights are left on while the vehicle
is stationary.
Why does the battery run flat?
● When stationary for a long time without starting the engine, particularly
if the ignition is switched on.
● Use of electrical consumers with the engine switched off.
● If the auxiliary heater is running ⇒ page 165.
WARNING
Incorrectly securing the battery or using the wrong battery can cause
short-circuits, fire and serious injuries.
● Always use only maintenance free batteries that do not run flat alone
and whose properties, specifications and size correspond to the stand-
ard battery. The specifications are indicated on the battery case.
WARNING
A highly explosive mixture of gases is released when the battery is under
charge.
● The batteries should be charged in a well-ventilated room only.
● Never charge a frozen or recently thawed battery. A flat battery can al-
so freeze at temperatures close to 0 °C (+32 °F).
WARNING (Continued)
● Always replace a battery which has frozen.
● Battery cables not correctly connected may cause a short circuit. Re-
connect first the positive cable and then the negative cable.
CAUTION
● Never disconnect the battery if the ignition is switched on or if the en-
gine is running. This could damage the electrical system or electronic com-
ponents.
● Never plug accessories supply current, such as solar panels or a battery
charger, to the 12-volt sockets or the cigarette lighter. This could damage
the vehicle's electrical system.
For the sake of the environment
● Dispose of the battery in an environment-friendly manner. Batteries con-
tain toxic substances such as sulphuric acid and lead.
● Battery acid can contaminate the environment. Collect any spilt service
fluids and allow a dispose of them correctly.
