Тут чуть подробнее:
Dynamic Braking
Two separate controls are required by law for brake operation, the brake pedal and handbrake
lever were previously used. In the E65, the footbrake and the push button in the
dashboard fulfills the requirements.
When the vehicle is moving and the engine is “OFF”, the EMF parking brake is applied when
pressure is maintained on the push button at speeds below 3 km/h. During this situation,
the parking brake is applied for 0.8 seconds. For the next 2 seconds there is an increase
in the braking power and the rate of deceleration is maintained as long as the push button
is pressed.
The Dynamic Braking function is active while the vehicle is rolling at speeds above 3 km/h
(when the ignition is in position KLR or KL15) when pressure is maintained on the push button.
This maintains vehicle stability by preventing overbraking of the rear axle using DSC
hydraulic pressure build-up application to the service brakes. The required brake pressure
is made available as fast as possible by the DSC.
Since braking takes place hydraulically on all four wheels, higher deceleration rates are possible
with minimum operating force as compared to the EMF parking brakes. This controlled
braking contributes to increased vehicle safety. For safety reasons, traffic is warned
when Dynamic Braking is active by the brake lights.
To avoid incorrect operation, the "Release Parking Brake" display and gong draw the driver's
attention to Dynamic Brake operation. This function should only be used in exceptional
circumstances.
When Dynamic Braking is activated until the vehicle comes to a stop, the vehicle will remain
held by the service brakes and the red P-indicator light remains on. If the brake pedal is
pressed during this operation, the DSC interprets this as a higher priority and will override
the parking brake function.
Exiting the dynamic emergency braking function: After emergency braking the vehicle to a
stop, the vehicle will remain held by the service brakes even after releasing the parking
brake push button. The service brakes will not be released until the push button is pressed
again.

был один желающий, но из-за размеров даже не знаю как до новой почты его дотащить.
