Using Snow Chains - BMW 5 Series GranTurismo Owner's Manual

Controls
At speeds up to approx. 37 mph/60 km/h, e.g.,
in curves, the steering angle is increased, i.e.,
steering becomes more direct.
The rear axle steering acts to increase maneu‐
verability by turning the rear wheels slightly in a
direction opposite to the front wheels.
At higher speeds, the steering angle is increas‐
ingly reduced.
The rear wheels are turned to the same angle as
the front wheels.
In critical situations, Integral Active Steering can
specifically steer the front and rear wheels to
stabilize the vehicle before the driver intervenes,
e.g., when braking where road conditions differ
on the left and right sides of the vehicle.
Initializing
In rare cases, it may become necessary to initi‐
alize the Integral Active Steering.
The warning lamp lights up. A Check
Control message is displayed.
1. With the engine running, turn the steering
wheel all the way to the left and right several
times in a uniform manner until the warning
lamp disappears.
2. Have the system checked if the warning
lamp does not go out after moving the steer‐
ing wheel approx. 6 times or if the steering
wheel is at an angle.

COMFORT+
Consistently comfort-oriented tuning of the In‐
tegral Active Steering for optimal traveling com‐
fort.
Malfunction
In the event of a malfunction, the steering wheel
must be turned further, while the vehicle re‐
sponds more sensitively to steering wheel
movements in the higher speed range.
The stability-enhancing intervention may be de‐
activated.
Proceed cautiously and drive defensively.
Have the system checked.
Self-leveling suspension
The concept
The self-leveling suspension keeps the vehicle
height and ground clearance constant. The
height of the vehicle at the rear axle is main‐
tained at a predefined level under all load con‐
ditions.
The system ensures consistent comfort by
keeping spring travel constant in all driving sit‐
uations.
Malfunction
A Check Control message is displayed. A mal‐
function has occurred in the self-leveling sus‐
pension. Vehicle handling may be altered and
driving comfort may be noticeably reduced. Visit
your nearest service center.
