Lane Assistance - Volvo XC 90 Owner's Manual

DRIVER SUPPORT

Lane assistance*

The purpose of Lane assistance is to help the
driver to reduce the risk of the vehicle acciden-
tally leaving its own lane in certain situations on
motorways and similar major routes.
There are two versions of Lane assistance:
•
Lane Departure Warning (LDW) - warns the
driver with an acoustic signal or vibrations in
the steering wheel.
•
Lane Keeping Aid (LKA) - steers the car
back into its lane and/or warns the driver by
an acoustic signal or steering wheel pulsa-
tions.
Lane Keeping Aid is active within the speed
range 65-200 km/h on roads with clearly visible
side lines.
On narrow roads the function may be unavailable,
in which case it goes into standby mode. The
function becomes available again when the road
is wide enough.
The steering wheel vibration varies - the longer the car stays outside the lane lines, the longer the vibration.

A camera reads the side lines of the road/lane.
Lane assistance steers the car back into its lane (LKA
only).
Lane assistance warns with steering wheel vibrations
How Lane assistance reacts is dependent on the
version and the settings:
1. Steering assistance activated (LKA only):
When the car is approaching a lane line, LKA
will actively steer the car back into its lane by
applying a slight torque to the steering
wheel.
2. Warning activated (LDW or LKA): If the car is
about to cross a lane line the driver is
warned by means of an acoustic signal or
vibrations in the steering wheel.
