Adaptive Cruise Control (ACC)
O
Adaptive Cruise Control (ACC) is an extension of the conventional cruise control system
with advanced capabilities based on a radar sensor. When ACC is activated, the vehicle
automatically brakes and accelerates to a speed and distance set by the driver.
If the Golf approaches a slower vehicle, the ACC brakes the car to the same speed and
maintains the pre-selected distance. Even when a vehicle pulls into the same lane in
front of you or slows, your vehicle is automatically decelerated to the pre-selected
distance. If the vehicle ahead moves out of your lane, the Golf then accelerates up to
the preset desired speed.
Deceleration of the vehicle may take place via intervention in the engine management
system. If deceleration via engine torque is not sufficient, brake intervention takes place,
braking the vehicle to a standstill if the traffic situation necessitates in vehicles equipped
with a DSG transmission. ACC can be reactivated automatically by depressing the
accelerator pedal. In vehicles fitted with a manual transmission, the system is
automatically deactivated at speeds below 30 km/h and the driver is prompted to take
charge by visual and acoustic signals.
The dynamics of the ACC system can by individually varied by selecting one of the driving
programs from the driver profile selector also available as part of the driver assistance
package.
Adaptive Cruise Control (ACC) 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 ACC system should not be
used on winding roads or in adverse weather conditions such as heavy rain.
Anti-lock Braking System (ABS)
When braking, wheel speed sensors measure the road wheel speed and should one
or more wheels start to lock the ABS system reduces brake pressure to that wheel.
This prevents the wheels from locking during heavy or emergency braking, enabling the
vehicle to remain steerable.
Anti-Slip Regulation (ASR)
ASR is a traction control system that prevents the wheels from spinning under
acceleration by reducing engine torque.
Auto Hold function
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.
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.
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 two separate gear sets operated by two clutches. The benefit
of two gear sets and two clutches is that one gear set and clutch is engaged driving the
vehicle with the second disengaged 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.
Driving Profile Selection
O
Driving profile selection provides the driver with a wide-ranging choice of settings that
can be made to the vehicle according to the driver’s preferences. The driver has the option
of choosing between the following driving profiles: Normal, Sport, Eco and Individual.
The Normal profile offers a comfortable but dynamic driving style. Sport provides faster
response of the accelerator pedal and steering while the DSG switches to Sport mode.
Eco mode has been designed to enhance fuel efficiency by including coasting function
(with DSG) and by adapting engine performance, earlier gearshift points and
consumption-optimised control of the air conditioning system. The Individual setting
allows the driver to separately set various parameters including steering, engine, Adaptive
Cruise Control (ACC) and air conditioning.
