When the risk of overheating is imminent, or in the event of overheating, (the temperature gauge goes
repeatedly into, or stays continually in, the red section) the following precautions should be taken:
Switch off the air conditioning system.
Stop the car and put the gear lever into neutral (position N). Do not stop the engine!
Increase the engine speed to approx. 2000 rpm (twice idling speed)
If the vehicle is overheating, switch the heater to full (maximum) position.
Electrical system
When replacing the battery or when carrying out work involving the electrical system, the following
should be observed:
A battery connection to the wrong terminal will damage the diodes. Before connections are made,
check the polarity of the
battery with a voltmeter.
If booster batteries are used for starting, they must be properly connected to minimize the risk of the
diode being damaged.
For correct connection, see "Jump starting" section.
Never disconnect the battery circuit (for example, to replace the battery) while the engine is running,
as this will immediately
ruin the generator. Always make sure that all the battery connections are properly tightened.
If any electrical/welding work is performed on the vehicle, the battery's ground lead (negative cable)
and all the connecting
cables of the generator must be disconnected and the welder cables placed as near the welding point as
possible.
