wards. And last but not least, cruise control with an integrated brake function
uses the automatic build-up of brake pressure via DSC to provide comfortable
and very pleasant speed control at all times.
Electromechanical parking brake and Auto-Hold function.
The BMW 5 Series Gran Turismo comes with a parking brake operated either
electromechanically or hydraulically, depending on current conditions, in the
interest of enhanced safety and motoring comfort.
With the engine running, the parking brake effect is generated by active build-
up of pressure in the hydraulic system controlled by DSC Dynamic Stability
Control. Then, as soon as the driver switches off the engine, the parking brake
effect is generated electromechanically.
The parking brake is activated by simply pulling the appropriate knob on the
centre console. To release the parking brake, in turn, all the driver has to do is
press the same knob while pressing down the brake pedal at the same time.
This configuration rules out the risk of the driver inadvertently releasing the
parking brake when the ignition is switched off.
While driving the driver is able to automatically build up an emergency braking
function by pulling the parking brake knob just a bit longer. The brake effect
itself is generated by actively building up hydraulic pressure on all four wheels,
the degree of stopping power being masterminded by the DSC control unit, tak-
ing the ABS function into account. Naturally, the brake lights are also activated in
the process.
The electromechanical parking brake comes complete with an Auto-Hold func-
tion. This combination quite unique in the market serves in particular to enhance
motoring comfort in stop-&-go traffic. As soon as the car comes to a standstill,
it is automatically held in position like on a gradient until the driver presses the
gas pedal again, without requiring him to keep the brake pedal down all the time
while the car is held in position.
The Auto-Hold function is activated and deactivated by a separate knob on the
centre console.
