Lane Keeping Aid (LKA) - function
Certain settings can be made for the Lane
Keeping Aid (Lane Keeping Aid) function.
Off & On
Lane Keeping Aid is active within the speed
range 65-200 km/h on roads with clearly visi-
ble side lines. The function is temporarily
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
illuminates when the function is switched on.
Some combinations of the selected equip-
ment 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. 114).
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 steer-
ing 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
activated, the car is steered back into the
lane.
Warning with vibration in steering wheel
LKA steers and alerts with steering wheel vibra-
tion
26
.
If the car crosses a side line then Lane Keep-
ing Aid will alert the driver with vibration in the
steering wheel
27
. This occurs regardless of
whether the car is actively steered back by
applying a slight steering torque.
26
The figure shows 3 vibrations when the side line is crossed.
27
Steering wheel vibration varies - the longer the time for which the car has crossed the side line, the more pulses there are.
