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

Dynamic Stability Control

Principle

The Antilock Braking System prevents locking

of the wheels during the braking process.

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.

You remain able to steer your vehicle even dur-

ing full braking, which increases active driving

safety.

General information

The Antilock Braking System is ready after

each time drive-ready state is turned on.

General information

The system detects the following unstable

driving conditions, for instance:

▷

Skidding, which can lead to oversteering.

Malfunction

Loss of adhesion of the front wheels, which

can lead to understeering.

The warning light on the instrument

cluster illuminates.

A Check Control message is displayed.

Safety information

Warning

▷

The Antilock Braking System is not availa-

ble.

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, and property damage. Adjust

driving style to traffic conditions. Watch the

surrounding traffic situation closely, be ready

Steerability is limited during full braking.

Have the vehicle checked immediately by an

authorized service center or another qualified

service center or repair shop.

BMW xDrive

Dynamic Stability Control

Principle

BMW xDrive is the all-wheel-drive system of

the vehicle. Concerted action by the BMW

xDrive and other suspension control systems

218

Driving stability control systems

CONTROLS

such as Dynamic Stability Control further opti-

mizes traction and driving dynamics.

Hill Descent Control

Principle

General information

Hill Descent Control is a downhill control fea-

ture that adjusts the vehicle speed on steep

downhill gradients, e.g., when driving on un-

paved roads.

BMW xDrive variably distributes the drive

forces to the front and rear axles as required

by the driving situation and road conditions.

With the xOFFROAD package, the all-wheel-

drive system is also adjusted to the respective

xOFFROAD driving mode.

General information

When the system is active, the vehicle moves

at the speed set by the driver, without the

driver having to depress the brake pedal.

Display on the control display

In the Live Vehicle menu, information about

BMW xDrive can be displayed under the fol-

lowing view:

While Hill Descent Control is adjusting the

speed, the system automatically distributes the

brake power to the individual wheels. This im-

proves driving stability and steerability. If nec-

essary, the Antilock Braking System prevents

the wheels from locking.

"xVIEW"

The following information is displayed:

▷

Distribution of drive torque to the wheels.

Hill Descent Control can be enabled at speeds

below approx. 25 mph/40 km/h.

Indication of longitudinal inclination in per-

cent.

Speeds can be set between approx.

2 mph/3 km/h and approx. 20 mph/30 km/h.

When the vehicle is driving downhill, the sys-

tem reduces the speed to the set value, within

the physical limits.

▷

Indication of lateral inclination in percent.

Graph of wheel angle.

Level adjustment of the two-axle ride level

control.

▷

With navigation system: elevation for the

current position.

Hill Descent Control provides assistance when

driving in selector lever positions D, N, and R.

Additional information:

Overview

Live Vehicle, refer to page 146.

Button in the vehicle

M sport differential

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.

The driver is responsible adapting his or her

driving style to the situation.

220

Driving stability control systems

CONTROLS

The system provides the steering force with

Using snow chains

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.

In order to guarantee free movement of the

wheels when operating with snow chains,

rear-wheel steering must be turned off when

snow chains are mounted.

Additional information:

Setting

Rear-wheel steering during operation with

snow chains, refer to page 362.

The steering force adapts to the drive mode

to convey a firm, sporty feel or a comfortable

steering response.

Malfunction

The warning light on the instrument

cluster illuminates.

Integral Active Steering

A Check Control message is displayed.

Principle

The steering system may not be operational.

Integral Active Steering assistance may no lon-

ger be provided.

The Integral Active Steering increases the ma-

neuverability of the vehicle and makes a more

direct steering response possible. Driving sta-

bility is also increased at high speeds.

▷

Larger steering movements are required at

low speeds.

The response of the vehicle is more sensi-

tive in higher speed ranges.

General information

Integral Active Steering combines variable

sport steering with active rear-wheel steering.

Proceed cautiously and practice anticipa-

tory driving.

The rear-wheel steering acts to increase ma-

neuverability at low speeds by turning the rear

wheels slightly in the opposite direction to the

front wheels.

Have the vehicle checked by an authorized

service center or another qualified service cen-

ter or repair shop.

At higher speeds, the rear wheels are turned

in the same direction as the front wheels. For

instance, this results in a harmonious lane

change.

In critical driving situations, integral active

steering can stabilize the vehicle by automat-

ically steering the rear wheels, for example e.g.

when oversteering.

Setting

The system offers several different settings.

With the Driving Experience Control driving

modes, the system can be set to comfortable

or dynamic.

Additional information:

Driving Experience Control, refer to page 138.
