Warnings and Safety Regulations
TECHNICAL ITEMS OF SPECIAL IMPORTANCE
To prevent damage to the vehicle, the following instructions must be strictly
observed.
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, for the first 1,500 km (932 miles): drive carefully and
avoid accelerating sharply.
The following technical items of special importance apply to both the runningin
period and to the period thereafter.
After a cold start continue to drive in a low gear and 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
you notice anything unusual, such as strange engine and transmission noises,
smoke, or poor performance.
Do not let the engine idle for longer than necessary.. This is harmful to the engine
and also causes unnecessary pollution of the environment.
Be aware that engine stalling while driving will lead to power steering failure.
Consequently, the vehicle will be more difficult to steer.
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. It is important to let the
engine run for a while in order to prevent the coolant temperature becoming too high
and to allow the turbocharger to cool down.
The engine cooling system is thermostatically controlled.
