Driving stability control systems

Vehicle features and options Brake assistant

This chapter describes all standard, country-

specific, and optional equipment offered with

the series. It also describes features and func-

tions that are not necessarily available in the

vehicle, e.g., due to the selected options or

country versions. This also applies to safety

functions and systems. When using these

functions and systems, the applicable laws

and regulations must be observed.

The brake assistant automatically applies

maximum braking assistance when the brake

pedal is depressed quickly. This reduces the

braking distance to a minimum for full braking.

To make full use of braking assistance, do not

reduce the pressure on the brake pedal during

full braking.

Drive-off assistant

Antilock Braking System

Principle

The drive-off assistant supports driving off on

uphill grades.

Principle

The Antilock Braking System prevents locking

of the wheels during the braking process.

Driving off

1. Hold the vehicle by depressing the brake

pedal.

You remain able to steer your vehicle even dur-

ing full braking, which increases active driving

safety.

2. Release the brake pedal and drive off

quickly.

General information

The Antilock Braking System is ready after

each engine start.

After the brake pedal is released, the vehicle is

held in place for approx. 2 seconds.

Depending on the vehicle loading, the vehicle

may roll back slightly.

Malfunction

In order to prevent rolling back when driving

off, use the parking brake.

The warning light on the instrument

cluster illuminates.

A Check Control message is displayed.

1.

Pull and release switch before driving

off.

The parking brake is set.

▷

The Antilock Braking System is not availa-

ble.

2. Step on the accelerator pedal sufficiently to

drive off.

Steerability is limited during full braking.

Have the vehicle checked immediately by an

authorized service center or another qualified

service center or repair shop.

Principle

Servotronic is a speed-dependent power

steering function.

Using the button

Press the button and select the de-

sired program on the control display.

The system provides the steering force with

more support at low speeds than at higher

ones. This makes it easier to park, for instance,

and makes steering firmer when driving at

faster speeds.

Via iDrive

It is possible to configure the required program

for buttons M1 or M2.

Furthermore, the steering force adapts accord-

ing to the program, so that a firm, sporty

feel or a comfortable steering response is con-

veyed.

Overview

Dynamic Stability Control

Button in the vehicle

Principle

The Dynamic Stability Control helps to keep

the vehicle on a steady course by reducing

drive power and by brake intervention on indi-

vidual wheels.

General information

The Dynamic Stability Control will detect, e.g.,

the following unstable driving conditions:

▷

Skidding, which can lead to oversteering.

DSC OFF

Loss of adhesion of the front wheels, which

can lead to understeering.

Deactivating/activating the Dynamic

Stability Control

Safety information

General information

Warning

If Dynamic Stability Control is deactivated, driv-

ing stability is limited when accelerating and

cornering.

The system cannot serve as a substitute for

the driver’s personal judgment in assessing

the traffic situation. Based on the limits of

the system, it cannot independently react to

all traffic situations. There is a risk of acci-

dent, injury, or property damage. Adjust driv-

ing style to traffic conditions. Watch the sur-

rounding traffic situation closely, be ready to

take over steering and braking at any time,

and actively intervene where appropriate.

To support driving stability, reactivate Dynamic

Stability Control as soon as possible.

Deactivating the system

Hold the button down until DSC OFF

is displayed in the instrument cluster

and the DSC OFF indicator light is illu-

minated.

Warning

M xDrive appears on the control display. The

required program can be selected.

When driving with a roof load, e.g., roof bars,

the vehicle's center of gravity is higher. This

increases the risk of the vehicle tipping in crit-

ical driving situations. There is a risk of acci-

dent, injury, or property damage. Drive with

roof load only with activated Dynamic Stabil-

ity Control.

Additional information:

M xDrive, refer to page 224.

Activating the system

Press the button.

DSC OFF and the DSC OFF indicator

light turn off.

CONTROLS

To support driving stability, reactivate the Dy-

namic Stability Control.

Display

ter.

Safety information

Warning

When M Dynamic Mode is activated, stabi-

lizing interventions are carried out only to a

reduced extent. There is a risk of accident, in-

jury, or property damage. Adjust driving style

to traffic conditions. Watch surrounding traf-

fic closely and actively intervene where ap-

propriate Do not jerk the steering wheel in

response to a warning.

Indicator lights and warning lights

Indicator light illuminates: Dynamic

Stability Control is deactivated.

Warning light flashes: Dynamic Stabil-

ity Control is regulating the drive and

brake power.

Warning light illuminates: Dynamic Stability

Control has failed.

Overview

Button in the vehicle

M Dynamic Mode

Principle

M Dynamic Mode allows a ride with high longi-

tudinal and lateral acceleration but with limited

driving stability.

Only in the absolute limit range does the sys-

tem intervene for stabilization by reducing the

engine power and by brake interventions on

the wheels. In this driving condition, additional

steering corrections may be necessary.

Dynamic Stability Control

General information

Depending on vehicle equipment, the active

M xDrive mode is: "4WD SPORT" when M Dy-

namic Mode is activated.

Activate/deactivate

Using the button

Press the button.

In the following exceptional situations, it may

be expedient to briefly activate M Dynamic

Mode:

Via iDrive

▷

When rocking the vehicle free from deep

snow or driving off from loose ground.

It is possible to configure M Dynamic Mode for

buttons M1 or M2.

▷

With an increased need for dynamics or

longitudinal acceleration, for instance when

driving on a race track.
