¹⁷⁸ⁿDynamic Stability Control (DSC)

Safety belt tensioner

Highly sensors monitor the number of

revolutions of the wheels, the steering

angle, lateral acceleration, brake pres-

sure and the movement of the vehicle

around its vertical axis.

You may need some time to become

accustomed to this system intervention.

However, it provides optimum drive

force and vehicle stability.

The braking intervention is accompa-

nied by sounds specific to the system.

If differences in the wheel speeds

occur, the system counteracts the

danger of wheelspin by reducing engine

torque. If necessary, the system also

responds with additional braking inter-

vention at all four wheels.

In addition, DSC permanently monitors

the vehicle's current operating condi-

tion and compares it with an ideal

condition that is calculated from the

sensor's signals. If deviations from this

occur (understeering or oversteering,

for instance), DSC can stabilize the

vehicle in fractions of a second by

reducing engine output and with the

assistance of braking intervention at

individual wheels. As a result,

The safety belt tensioner responds to

severe frontal collisions by tightening

the belts to ensure that occupants

remain firmly positioned in their seats.

buckle assembly to tension the

shoulder and lap belts within fractions

of a second. This reduces the tendency

to slide under the lap belt.

dangerous skids can be prevented even

as they are just beginning.

The electronic control system operates

by comparing the respective levels of

luminous intensity in front of and behind

the car. The difference provides the

basic parameter used to modulate an

electrical current and induce chemical

changes in a semisolid layer incorpo-

rated in the lens.

The semisolid reacts chemically to this

electrical current, thus providing infi-

nitely-variable dimming of the mirror

(electrochromic technology).

As a result, it is no longer necessary

to dim the mirror manually, and the

driver can maintain full concentration

on traffic.
