Driving
- When driving a vehicle combination, check whether the parking brake lever can
be moved even further backwards from position B against the pressure of the
spring. Press in the parking brake lever and pull it further back (to position C).
This is the test position, the drawn vehicle's brakes are not applied in this
position. Check that the vehicle combination remains in place.
- Let the parking brake spring back to position B.
- Place chocks in front of and behind the wheels.
- Angle the front wheels so that the vehicle will not move into the traffic stream if it
is accidentally set in motion.
If the vehicle combination does not remain in place in the test position, find a flatter
place to park the vehicle. Always carry out this test if the vehicle is parked in
unfavourable circumstances (gradient, slippery road surface, etc.). In this way, the
combination will remain safely parked, even if air leakage should make the drawn
vehicle brakes ineffective.
Switch off the engine.
Put the gear lever in neutral when the vehicle is stationary.
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.
Switch the engine off by turning the ignition key to 0 position (rest position).
