Lane Keeping Aid (LKA) - function
Certain settings can be made for the Lane Keep-
ing Aid (Lane Keeping Aid) function.
Off & On
Lane Keeping Aid is active within the speed
range 65-200 km/h (40-125 mph) on roads with
clearly visible side lines. The function is temporar-
ily deactivated on narrow roads with less than 2.6
metres between the lane's side lines.
Press the centre console's button to activate or
deactivate the function. The button's lamp illumi-
nates when the function is switched on.
Some combinations of the selected equipment
leave no vacant space for an On/Off button in
the centre console - in which case the function is
instead handled in the car's menu system MY
CAR. For a description of the menu system, see
MY CAR (p. 117).
In addition, the following selections can be made
in MY CAR:
•
Warning with vibration in the steering wheel:
Vibration only - On or Off.
•
Active steering:
Steering assist only- On or
Off.
•
Both Warning with vibration in the steering
wheel and Active steering:
Full function -
On or Off.
Active steering
Lane Keeping Aid strives to keep the car within
the side lines for the lane.
LKA intervenes and steers away.
If the car approaches the left or right side line of
the lane and the direction indicator is not acti-
vated, the car is steered back into the lane.
Warning with vibration in steering wheel
LKA steers and alerts with steering wheel vibration
28
.
If the car crosses a side line then Lane Keeping
Aid will alert the driver with vibration in the steer-
ing wheel
29
. This occurs regardless of whether
the car is actively steered back by applying a
slight steering torque.
28
The figure shows 3 vibrations when the side line is crossed.
29
Steering wheel vibration varies - the longer the time for which the car has crossed the side line, the more pulses there are.
