Glossary.

4MOTION

An all-wheel-drive system that provides the best possible

traction at all road speeds, in all weather and road conditions.

An electronic Haldex clutch responds to traction losses at the front

and rear axles and directs torque to the axle with the best traction.

Adaptive Chassis Control

The electrically controlled dampers of adaptive chassis control

constantly adjust to the road conditions, the driving situation

and driver’s requirements. Using a button located on the centre

console, the driver selects between three damper settings –

NORMAL, COMFORT and SPORT.

Starting from the normal setting, the driver can change the basic

character of the car towards sporty or more comfort-oriented

driving. In SPORT and COMFORT settings, the corresponding

name is illuminated in the button. In NORMAL setting, only

the shock absorber symbol is illuminated. In all settings, the

adaptive chassis control adjusts the damping to the particular

driving situation (up till one thousand times per second)

which means it offers an optimum level of driving comfort and

enjoyment at all times. In addition, in the SPORT setting the

steering feel is also adapted. Particularly on windy roads and

poor surfaces, using adaptive chassis control offers sporty and

yet comfortable driving.

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 switchable traction control system that prevents the wheels

from spinning under acceleration by reducing engine torque.

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 2

separate gear sets operated by 2 clutches. The beneﬁ t 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.

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 Diﬀ erential 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.

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.

Extended Electronic Diﬀ erential 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 the inside of the corner

in order to prevent wheel spin. This improves traction and reduces

the tendency to understeer. As a direct result of the one-sided and

precise braking pressure, cornering is sportier and more accurate.

Hill Start Assist (HSA)

Hill Start Assist (HSA) holds the vehicle when the foot brake is

released by temporarily locking the brake pressure (for a maximum

of 1.5 seconds) to provide comfortable starting-off without rolling

back. Hill Start Assist (HSA) operates on inclines greater than 5%

and is ﬁ tted in combination with both the manual transmission and

the Direct Shift Gearbox (DSG).

Park Assist

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

sufﬁ cient space, the driver stops the car, selects reverse and let’s go

of the steering wheel.

Park Assist will alert the driver of the intended reverse path in the

Multi-Function Display, within the driver’s ﬁ eld 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, if necessary with several moves. 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.

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.
