Warnings and safety regulations
The following technical items of special importance apply to both the running-in
period and to the period thereafter.
After a cold start , use a low gear and drive at a moderate engine speed until the
engine coolant temperature is out of the blue zone.
While driving, check the instrument panel regularly and take appropriate action if
there is anything unusual.
Unusual operation may include strange engine and transmission noises, smoke or poor
performance.
Do not let the engine
idle longer than necessary . This is harmful to the engine and
also causes unnecessary pollution of the environment.
Be aware that engine stalling while driving leads to power steering failure.
Consequently, vehicle steering is more difficult.
Before switching off the engine after a long trip or when the engine has been
subjected to high loading , let it idle for at least 5 minutes. Let the engine run for a
while to prevent the coolant temperature becoming too high and to allow the turbo
charger to cool down.
The engine cooling system is thermostatically controlled.
Removing the thermostat when the coolant temperature is (too) high is strongly
advised against, since this causes the engine temperature to rise to an even higher
level.
The turbo charger is a precision component. Immediately report any abnormal noises
produced by this component.
Running-in
During the running-in period it is best not to subject the new vehicle to excessive loads.
This also applies when an overhauled engine, gearbox or differential has been
installed. Therefore, drive carefully and avoid accelerating sharply for the first 1500 km.
System voltage
The vehicle is equipped with a 24-volt electrical system.
When replacing or fitting electrical or electronic components, always check that the new
components are suitable for this system voltage.
Connecting accessories
Never connect accessories or any other electrical components to the vehicle by splicing
the vehicle wiring or connecting it to electrical components. Failure to meet these
conditions may have serious consequences on the electrical systems within the vehicle
and can result in short circuits and fire.
