glossary adaptive cruise control acc direct shift gearbox dsg 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 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 clutches the benefit of 2 gear sets and 2 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 if the polo 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 polo 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 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 distance to the vehicle in front can be pre-set in the car menu of the composition colour audio system and individually varied via the multi-function steering wheel the status of the acc system can be viewed in driver assistance systems menu in the multi-function display mfd plus adaptive cruise control acc cannot replace the driver’s attentiveness 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 driven wheels from spinning under acceleration by reducing engine torque it is active at speeds above 40 km/h 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 12 glossary electronic brake-pressure distribution ebd 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 differential lock edl edl improves driving and steering characteristics when accelerating on road surfaces where each wheel has a different degree of traction the system operates automatically and is combined with the abs system using the abs wheel sensors edl monitors the speed of the individual driving wheels when a difference in driving wheel speed is detected i.e when one wheel starts to spin due to differences in road surfaces e.g due to water or dirt the system brakes the spinning wheel transferring engine power to the wheel with the best traction edl is active in forward and reverse and operates up to 40 km/h 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 reduces the effects of understeer or oversteer extended electronic differential lock xdl xdl is an extension of the electronic differential lock edl function when cornering xdl responds to the load relief at the front wheel on the inside of a corner the esp hydraulics are used for the xdl to apply pressure to the wheel on
