Auto Hold function
Park Assist*
As soon as the vehicle comes to a complete stop, the ABS hydraulic
unit stores the vehicles final braking pressure. So even when you take
your foot off the brake pedal, all four wheels brakes remain applied,
providing increased comfort in stationary traffic. This function is
released automatically when you drive off again.
Park Assist actively helps the driver when reversing into parallel
parking spaces. The system works by using sensors mounted either
side of the front bumper together with parking distance sensors
front and rear. To parallel park the driver needs to press the Park
Assist button and use the appropriate indicator before the car
passes the potential parking space. Sensors in the front bumper
then scan the size of the parking space as the car is driven slowly
past and the driver is alerted if the parking space is big enough.
If there is sufficient space, the driver stops the car, selects reverse
and let’s go of the steering wheel.
Brake Assist
During emergency braking, Brake Assist aids the driver by increasing
the brake pressure automatically to a level exceeding the locking
limit. The ABS is thus quickly brought into the operating range,
which enables maximum vehicle deceleration to be achieved.
Park Assist will alert the driver of the intended reverse path in the
Multi-Function Display, within the driver’s field of vision. Park
Assist then actively supports the driver by taking over the steering
control and parks the vehicle in the available space using the ideal
course. The driver can however take over the control of the steering
at any time and end the automatic parking procedure. The system
can reverse into parking spaces on both the left hand and right
hand side of the road, for example on one way streets.
Direct Shift Gearbox (DSG)
DSG is a manual gearbox in which the gearshifts are controlled
electronically. What makes the DSG unique is that it has 2 separate
gear sets operated by 2 wet multi-plate clutches. The benefit of 2
gear sets and 2 multi-plate wet clutches is that one gear set and
clutch is engaged driving the vehicle with the second clutch having
already pre-selected the next gear awaiting for power to be transferred.
As the next gear has already been pre-selected prior to power being
applied, the gear change only takes 3-4 100ths of a second. There is
virtually no interruption to power, traction or acceleration. The DSG
also offers Tiptronic gear selection and sports mode.
Park Assist cannot replace the driver’s attentiveness. The driver is still legally
responsible for the vehicle. If the driver notices a risk that pedestrians, other
vehicles or objects could be damaged or if they are uncertain of the risk, they
will need to react accordingly and stop the vehicle, ending the function.
Electronic Brake-pressure Distribution (EBD)
*Optional equipment
Electronic, more sophisticated means of regulating the ratio of front/
rear brake pressure. Settings are varied according to driving and load
conditions to ensure each wheel is braked to the optimum extent.

Electronic Stabilisation Program (ESP)
ABS and ASR traction control systems are integrated into the
Electronic Stabilisation Program (ESP). In short, ESP helps ensure
that the vehicle goes where you steer it even in extreme driving
conditions. The ESP system constantly compares the actual
movement of the vehicle with pre-determined values and should
a situation arise where the vehicle starts to skid, ESP will apply the
brakes to individual wheels and automatically adjust the engine’s
power output to correct the problem. ESP prevents the vehicle from
losing control when trying to avoid an accident, for example. It also
prevents spinning off on a curve due to either understeer or oversteer.
Front Assist*
The Front Assist ambient traffic monitoring system uses a radar
sensor to detect critical distance situations and thus help to shorten
the braking distance, reducing the risk of a rear-end collision.
The system warns the driver of a dangerous situation in two stages.
Preliminary warning – A visual warning appears in the instrument
panel simultaneously an acoustic signal is given. At the same time
the Brake Assist system is switched to ‘increased sensitivity’.
Main warning – If the driver does not react, the Brake Assist system
is prepared to ‘maximum sensitivity’ and a brief braking jolt is
activated to draw the driver’s attention to the risk of a collision.
Front Assist cannot replace the driver’s assertiveness. The driver is still legally
responsible for the vehicle and must monitor the speed and distance in
relation to other vehicles. The barking jolt does not reduce the speed of the
vehicle. The Front Assist system does not activate at a vehicle speed of less
than 30km/h.
