Vehicle equipment

Dynamic Stability Control

DSC

This chapter describes all standard, country-spe‐

cific and special equipment available for the

model series. It may therefore describe equip‐

ment which is not installed in your vehicle, for ex‐

ample on account of the optional equipment se‐

lected or the country variant. This also applies to

safety-relevant functions and systems. Please

comply with the relevant laws and regulations

when using the corresponding functions and

systems.

Principle

The system reduces engine power output and

applies the brakes on individual wheels thereby

helping, within the limits imposed by the laws of

physics, to keep the vehicle safely on course.

General

DSC detects the following unstable driving con‐

ditions, for example:

▷ Loss of traction at the rear which can lead to

oversteer.

Anti-lock Brake System

ABS

▷ Loss of grip at the front wheels which can

lead to understeer.

ABS prevents the wheels from locking when the

brakes are applied.

Dynamic Traction Control DTC, see page 177,

is a variant of DSC optimised for forward mo‐

mentum.

Steering control is retained even during full brak‐

ing, thereby enhancing active road safety.

ABS is operational each time the engine is star‐

ted.

Safety notes

WARNING

Brake assist

The system does not relieve you of your per‐

sonal responsibility to assess the traffic situa‐

tion correctly. Due to system limitations, it can‐

not respond independently and appropriately in

all traffic conditions. There is a risk of accident.

Adapt your driving style to the traffic conditions.

Observe the traffic situation and intervene ac‐

tively if the situation warrants it.

When the brake is pressed quickly, this system

automatically applies maximum braking power

assistance. This keeps the stopping distance as

short as possible in full braking situations. The

advantages offered by the Anti-lock Brake Sys‐

tem ABS can also be utilised to the full.

The pressure on the brake should be maintained

for the duration of the full-braking process.

WARNING

When driving with a roof load, for example with

a roof rack, the higher centre of gravity can

mean that driving safety is no longer guaran‐

teed in critical driving situations. There is a dan‐

ger of accidents or damage to property. Do not

deactivate Dynamic Stability Control DSC when

driving with a roof load.

Steering and, depending on equipment, suspen‐

sion are tuned for dynamic driving.

Activating DSC

Overview

Press the button.

DSC OFF and the DSC OFF indicator

lamps are extinguished.

Indicator and warning lamps

DSC OFF is displayed in the instrument cluster

If the indicator lamp is illuminated: DSC is

DSC OFF button

Dynamic Traction Control

DTC

Indicator and warning lamps

Principle

DTC is a variant of Dynamic Stability Control

DSC and is optimised for forward momentum.

If the indicator lamp is flashing: DSC is

regulating the acceleration and braking

forces.

In special road conditions, for example roads on

which snow has not been cleared or on a loose

surface, the system ensures maximum forward

momentum but with somewhat limited driving

stability.

If the indicator lamp is illuminated: DSC has

failed.

Deactivating DSC: DSC OFF

General

Driving stability during acceleration and cornering

is restricted if DSC is deactivated.

Activating DTC provides maximum traction. Driv‐

ing stability during acceleration and cornering is

reduced.

Drive carefully.

To assist driving stability, re-activate DSC as

soon as possible.

It may be useful to activate DTC briefly in the

following exceptional situations:

▷ When driving in slush or on uncleared, snow-

covered roads.

Deactivating DSC

Press and hold the button – but for no

longer than approximately 10 seconds –

until the DSC OFF indicator lamp in the instru‐

ment cluster is illuminated and DSC OFF is dis‐

played.

▷ When starting in deep snow or on a loose

surface.

▷ When driving with snow chains.

DSC is switched off.

Deactivating DTC

Variable sports steering

The support offered by the variable sports steer‐

ing changes according to the angle by which the

steering wheel has been turned and the speed.

xDrive

So, for example the steering angle of the front

wheels is made larger when parking or taking

tight corners. This makes it easier to drive

around bends.

xDrive is the four-wheel drive system of the vehi‐

cle. The combination of xDrive and Dynamic Sta‐

bility Control DSC further optimises traction and

driving dynamics. The xDrive four-wheel drive

system distributes the drive forces variably to the

front and rear axles according to the driving sit‐

uation and road surface conditions.

Furthermore, the system provides the steering

with more support at low speeds than at higher

speeds. This makes it easier to park, for example,

and provides a more direct steering feel when

driving at higher speeds.

Adaptive suspension

By taking both steering wheel angle and vehicle

speed into account, it has been possible to ach‐

ieve a sport steering response adapted to the

particular driving situation.

Principle

The system reduces unwanted vehicle move‐

ments when a dynamic driving style is used or

when driving on uneven roads.

Servotronic

Depending on road conditions and driving style,

driving dynamics and driving comfort are en‐

hanced as a result.

Principle

Servotronic is a speed-dependent power steer‐

ing system.

Programs

It provides different programs.

The system provides more steering force assis‐

tance at lower speeds than at higher speeds.

This makes it easier to park, for example, and

provides a firmer steering feel when driving at

higher speeds.

The programmes can be selected using the Driv‐

ing Experience Control.

Principle

DSC OFF

When you select DSC OFF, see page 177, driv‐

ing stability during acceleration and cornering is

restricted.

The Driving Experience Control allows certain

vehicle characteristics to be adapted. Various

programs can be selected for this purpose. Us‐

ing the Driving Experience Control and using the

DSC OFF button, one programme can be activa‐

ted in each case.

TRACTION

With TRACTION you have maximum traction on

loose surfaces. Dynamic Traction Control DTC,

see page 177, is activated. Driving stability dur‐

ing acceleration and cornering is reduced.
