Driving stability control systems

Vehicle features and options Brake assistant

This chapter describes model-specific equip-

ment, systems, and functions that are currently

available, or may become available in the fu-

ture, even if they are not present in the vehicle.

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.

Additional information:

To make full use of braking assistance, do not

reduce the pressure on the brake pedal during

full braking.

Vehicle equipment, refer to page 8.

Antilock Braking System

Drive-off assistant

Principle

The Antilock Braking System prevents locking

of the wheels during the braking process.

The drive-off assistant supports driving off on

uphill grades.

You remain able to steer your vehicle even dur-

ing full braking, which increases active driving

safety.

Driving off

1. Hold the vehicle by depressing the brake

pedal.

General information

The Antilock Braking System is ready after

each time drive-ready state is turned on.

2. Release the brake pedal and drive off

quickly.

After the brake pedal is released, the vehicle is

held in place for approx. 2 seconds.

Malfunction

Depending on the vehicle loading, the vehicle

may roll back slightly.

The warning light on the instrument

cluster illuminates.

In order to prevent rolling back when driving

off, use the parking brake.

A Check Control message is displayed.

▷

The Antilock Braking System is not availa-

ble.

1.

Pull and release switch before driv-

ing off.

Steerability is limited during full braking.

The parking brake is set.

Have the vehicle checked immediately by an

authorized service center or another qualified

service center or repair shop.

2. Step on the accelerator pedal sufficiently to

drive off.

Driving stability control systems

CONTROLS

Overview

Dynamic Stability Control

Button in the vehicle

Principle

Dynamic Stability Control helps keep the vehi-

cle on a steady course in critical driving situa-

tions. The drive power is reduced depending

on the situation, and wheels can be braked

individually.

General information

The system detects the following unstable

driving conditions, for instance:

Dynamic Stability Control

▷

Skidding, which can lead to oversteering.

Loss of adhesion of the front wheels, which

can lead to understeering.

Activating/deactivating Dynamic

Stability Control

Safety information

General information

Warning

Dynamic Stability Control is automatically acti-

vated whenever drive-ready state is switched

on.

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.

If Dynamic Stability Control is deactivated, driv-

ing stability is limited when accelerating and

cornering.

To support driving stability, reactivate Dynamic

Stability Control as soon as possible.

Activating/deactivating the system

1.

Press the button to open the menu.

Warning

2. "DSC OFF"

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.

Dynamic Stability Control is deactivated.

3.

Press the button again to reactivate

Dynamic Stability Control.

lowed snow covered roads or loose road surfa-

ces, but with somewhat limited driving stability.

View when Dynamic Stability

Control is deactivated.

General information

The vehicle has maximum traction when Dy-

namic Traction Control is on. Driving stability

is limited during acceleration and when corner-

ing.

Indicator light illuminates: Dynamic

Stability Control is deactivated.

A brief activation of the Dynamic Traction Con-

trol may be useful in the following situations:

Warning light flashes: Dynamic Stabil-

ity Control is regulating the driving and

brake power. The vehicle is stabilized.

Reduce speed and modify your driving style to

the driving circumstances.

▷

When driving in slush or on uncleared,

snow-covered roads.

When driving off from deep snow or loose

ground.

When driving with snow chains.

Warning light illuminates: Dynamic Sta-

bility Control has failed or is initializing.

Driving stabilization is restricted or has

failed.

Overview

Button in the vehicle

If the warning light illuminates continuously,

have the vehicle checked immediately by an

authorized service center or another qualified

service center or repair shop.

Automatic program change

Dynamic Stability Control can be activated au-

tomatically by Forward Collision Mitigation de-

pending on the situation. Deactivate Forward

Collision Mitigation as necessary.

vention, refer to page 168.

Displays in the instrument cluster

M sport differential

View when Dynamic Traction

Control is activated.

The M Sport differential provides for continu-

ously variable locking of the rear axle differen-

tial, depending on the driving situation. This

prevents spinning of a single rear wheel and

thereby provides optimal traction in any driving

situation.

Indicator light illuminates: Dynamic

Traction Control is activated.

The driver is responsible adapting his or her

driving style to the situation.

Automatic program change

In certain situations, Dynamic Stability Control

is activated automatically:

Servotronic

▷

Active Cruise Control with Distance Control

is activated.

Principle

Servotronic is a speed-dependent steering

support.

▷

In case of a brake intervention by For-

ward Collision Mitigation. Deactivate For-

ward Collision Mitigation as necessary.

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.

▷

If the suspension control system fails.

The vehicle has a flat tire.

Additional information:

Forward Collision Mitigation with brake inter-

vention, refer to page 168.

Setting

The steering force adapts to the drive mode

to convey a firm, sporty feel or a comfortable

steering response.

BMW xDrive

Principle

Variable sport steering

BMW xDrive is the all-wheel-drive system of

the vehicle. Concerted action by the BMW

xDrive and other suspension control systems

such as Dynamic Stability Control further opti-

mizes traction and driving dynamics.

The variable sports steering facilitates direct

and agile handling with little steering effort.

The variable sports steering responds inde-

pendently of the current speed, varying the

steering gear ratio in line with the steering an-

gle.

General information

BMW xDrive variably distributes the drive

forces to the front and rear axles as required

by the driving situation and road conditions.

▷

In situations that require large movements

of the steering wheel, e.g., when maneu-

vering or turning, even minor movements of

the steering wheel will result in a greater

wheel steering angle. As a result, the varia-

ble sports steering increases steering com-

fort by reducing the necessary steering ef-

fort.

▷

The wheel angle is reduced in situations

that require minor or rapid corrections of

the direction of travel when driving at higher

speeds, e.g., swerving quickly or correcting

for crosswinds. In these cases, the variable

sports steering increases driving stability

when moving the steering wheel.
