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.

Driving stability control systems

CONTROLS

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, and property damage. Adjust

driving style to traffic conditions. Watch the

surrounding 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

Activating the system

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

critical driving situations. There is a risk of

accident, injury, and property damage. Drive

with roof load only with activated Dynamic

Stability Control.

Press the button.

DSC OFF and the DSC OFF indicator

light turn off.

If the Dynamic Stability Control is deactivated,

DSC OFF is displayed in the instrument clus-

ter.

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.

DSC OFF

Warning light illuminates: Dynamic Stability

Control has failed.

Activating/deactivating the Dynamic

Traction Control

Dynamic Traction Control

Activating the system

Press the button.

Principle

The Dynamic Traction Control is a variant of

the Driving Stability Control where the drive

power is optimized.

TRACTION is displayed in the instru-

ment cluster and the indicator light for DSC

OFF illuminates.

The system ensures maximum drive power

on unusual road conditions, for instance unp-

lowed snow covered roads or loose road surfa-

ces, but with somewhat limited driving stability.

Deactivating the system

Press the button again.

TRACTION and the DSC OFF indica-

tor light turn off.

General information

The vehicle has maximum traction when Dy-

namic Traction Control is on. Driving stability

is limited during acceleration and when corner-

ing.

Display

Display in the instrument cluster

When the Dynamic Traction Control is acti-

vated, TRACTION is displayed in the instru-

ment cluster.

A brief activation of the Dynamic Traction Con-

trol may be useful in the following situations:

▷

When driving in slush or on uncleared,

snow-covered roads.

Indicator light

When driving off from deep snow or loose

ground.

Indicator light illuminates: Dynamic

Traction Control is activated.

When driving with snow chains.

Hill Descent Control

The vehicle has a flat tire.

Principle

BMW xDrive

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.

Principle

BMW xDrive is the all-wheel-drive system of

the vehicle. BMW xDrive and other suspension

control systems, e.g., Dynamic Stability Con-

trol, work together to further optimize traction

and driving dynamics.

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.

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.

General information

BMW xDrive variably distributes driving forces

to the front and rear axles as required by the

driving situation and road conditions.

Because of the needs-based use of the all-

wheel-drive system, Efficient4x4 yields a re-

duction in consumption.

The system can be activated below approx.

25 mph/40 km/h.

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.
