Driving stability control systems

Controls

Driving stability control systems

DSC also recognizes unstable vehicle condi‐

tions such as fishtailing or nose-diving. Within

the physical limits DSC helps to keep the vehi‐

cle on a steady course by reducing engine

speed and by applying brakes to the individual

wheels.

Vehicle features and options

This chapter describes all standard, country-

specific and optional features offered with the

series. It also describes features that are not

necessarily available in your car, e. g., due to

the selected options or country versions. This

also applies to safety-related functions and

systems. The respectively applicable country

provisions must be observed when using the

respective features and systems.

Note

Adjust your driving style to the situation

An appropriate driving style is always the

responsibility of the driver.

The laws of physics cannot be repealed, not

even with DSC.

Antilock Brake System ABS

Therefore, do not reduce the additional safety

margin by driving in a risky manner.◀

ABS prevents locking of the wheels during

braking.

The vehicle contains its steering power even

during full brake applications, thus increasing

active safety.

Do not deactivate DSC when driving with

roof load

Do not deactivate Dynamic Stability Control

DSC when driving with roof load, e.g. roof-

mounted luggage rack.

ABS is operational every time you start the en‐

gine.

Otherwise, driving safety is not given in driv‐

ing-critical situation due to the elevated center

of gravity.◀

Brake assistant

When you apply the brakes rapidly, this system

automatically produces the greatest possible

braking force boost. It reduces the braking dis‐

tance to a minimum during emergency stop.

This system utilizes all of the benefits provided

by ABS.

Overview

Button in the vehicle

Do not reduce the pressure on the brake pedal

for the duration of the emergency stop.

DSC Dynamic Stability

Control

DSC prevents traction loss in the power

wheels when driving off and accelerating.

Deactivating DSC: DSC OFF

When DSC is deactivated, driving stability is

reduced during acceleration and when driving

in curves.

Therefore drive with appropriate caution.

You may find it useful to briefly activate DTC

under the following special circumstances:

To increase vehicle stability, activate DSC

again as soon as possible.

Performance Control

Performance Control enhances the agility of

the vehicle.

DTC Dynamic Traction

Control

To increase maneuverability, with a corre‐

spondingly sporty driving style, wheels are

braked individually. The resulting braking

power is simultaneously largely compensated

by an engine intervention.

The concept

The DTC system is a version of the DSC where

forward momentum is optimized.

Increasing or decreasing vehicle

speed

Specify desired speed in the range from ap‐

prox. 4 mph/6 km/h to approx. 15 mph/25 km/h

using the rocker switch of the cruise control on

the steering wheel. Vehicle speed can be

changed by lightly accelerating.

xDrive

xDrive is the all-wheel-drive system of your ve‐

hicle. Concerted action by the xDrive and DSC

further optimize traction and driving dynamics.

The xDrive all-wheel-drive system variably dis‐

tributes the drive forces to the front and rear

axles as demanded by the driving situation and

road surface.

ally.

HDC Hill Descent Control

Press the rocker switch down past the

point of resistance: when driving forward,

the speed decreases to approx.

6 mph/10 km/h; when reversing, the speed

decreases to approx. 4 mph/6 km/h.

The concept

HDC is a downhill driving assistant that auto‐

matically controls vehicle speed on steep

downhill gradients. Without applying the

brakes, the vehicle moves at slightly more than

walking speed.

Activating HDC

Hill Descent Control can be activated at

speeds below approx. 22 mph/35 km/h. When

driving downhill, the vehicle reduces its speed

to approx. walking speed and then keeps its

speed constant.

As long as there is active braking, the system

is on standby. The system does not brake the

vehicle during this time.

Only use HDC in low gears or in selector lever

position D or R.

lights up.

Variable sport steering

Display in the instrument cluster

The variable sport steering increases the

steering angle of the front wheels at large

steering wheel angles, e.g., in tight curves or

when parking. Steering becomes more direct.

The selected speed is displayed

in the speedometer.

▷

Green: the system is actively

braking the vehicle.

It also varies the force required to turn the

wheels in accordance with the vehicle speed.

▷

Orange: the system is on

standby.

This results in a sporty steering response. In

addition, it becomes easier to steer during

parking and maneuvering.

Malfunction

A message is displayed in the instrument clus‐

ter. HDC is not available, e.g., due to elevated

brake temperatures.

Servotronic

The concept

The Servotronic varies the steering force re‐

quired to turn the wheels in accordance with

the vehicle speed. At low speeds, the steering

force is strongly supported, i. e. during steer‐

ing, low force is required. As the speed in‐

creases, the assistance of the steering force is

reduced.

Dynamic Damping Control

The concept

This system reduces undesirable vehicle mo‐

tion when using a dynamic driving style or trav‐

eling on uneven road surfaces.

Furthermore, the steering force adapts accord‐

ing to the driving program, so that a direct,

sporty feel and/or comfortable steering is con‐

veyed.

The system enhances driving dynamics and

comfort fitting road surface and driving style.

Programs

The system offers several different programs.

Select the programs via the Driving Dynamics

Control, refer to page 126.

Driving Dynamics Control
