Integral Active Steering
Concept
The Integral Active Steering increases the ma‐
neuverability and makes a more direct steering
response possible.
General information
Integral Active Steering is a combination of varia‐
ble steering ratio and rear axle steering.
The variable steering ratio amplifies the steering
angle when maneuvering, thus making the steer‐
ing more direct. The rear axle steering acts to in‐
crease maneuverability at low speeds by turning
the rear wheels slightly in the opposite direction
to the front wheels.
At higher speeds, the rear wheels are turned in
the same direction as the front wheels. This re‐
sults in, for instance better directional stability
and a more harmonious change of direction.
In critical driving situations, the Integral Active
Steering can stabilize the vehicle through pur‐
poseful steering of the rear wheels before the
driver intervenes, for instance in case of over‐
steering.
Tuning
The system offers several different tunings.
Driving mode Integral Active Steering
COMFORT
ECO PRO
comfortable, for optimal
travel comfort
SPORT dynamic, for greater agility
The different tunings are assigned to the differ‐
ent driving modes of the Driving Dynamics Con‐
trol, refer to page 134.
Using snow chains
In order to guarantee free running of the wheels
when operating with snow chains, rear axle
steering of the integral active steering must be
switched off when snow chains are mounted.
Set operation with snow chains, refer to
page 344.
Malfunction
In the event of a malfunction, the steering wheel
must be turned further, while the vehicle re‐
sponds more sensitively to steering wheel move‐
ments in the higher speed range.
The stability-enhancing intervention may be de‐
activated.
Proceed cautiously and drive defensively.
Have the system checked by a dealer's service
center or another qualified service center or re‐
pair shop.
