100 The steering wheel vibrations vary. The more time the vehicle is over the lane marker line, the longer the vibrations.

Depending on the settings used, Lane Keeping
Aid functions in different ways:

using light pressure on the steering wheel.
Warning 101
With activated: If the vehicle is
•
about to move over a lane marker line, the
driver will be alerted by vibrations in the
steering wheel.
NOTE

Lane Keeping Aid does not provide any warn-
ing or intervene with steering.
