Active Lane Assist (ALA) Activation Conditions and Functions

57x d 05.04.002

ALA is turned on each time the engine is turned on.

Lane departure protection (LDP) builds on lane departure warning (LDW). As soon as the vehicle reaches 37 mph (60 km/h), both LDW and LDP are on.

LDP requires both lane lines to be identifiable to function.

ALA is ready to issue warnings:

  • when the vehicle is moving above approximately 37 mph (60 km/h); and

  • the driver display shows solid lane markings; and

  • when the blue steering wheel indicator appears in the instrument panel.

When driving over the lane marking unintentionally:

  • the relevant lane marking is shown in red on the driver display screen;

  • the volume of the audio equipment and/or hands-free system is muted and a warning tone sounds from the loudspeaker on the corresponding side of the vehicle.

If a driver takes their hands off the steering wheel for fifteen seconds:

  • a ‘Hands On’ caution pop-up screen will appear.

ALA does not issue a warning about going over lane markings if:

  • the turn signals are switched on;

  • the driver clearly and actively steers, brakes or accelerates;

  • a driving safety system, such as Active Brake Assist intervenes.

ALA will warn the driver when changing lanes if the turn signal is not used.

Lane Departure Protection will steer a vehicle back into the center lane position three times before going into a passive state and requiring a key cycle to reactivate.

LKA is in a passive state while the driver actively steers the vehicle.

The status of LKA—shown with the steering wheel indicator—is shown by the color of indicator:

  • Blue steering wheel: LKA is active.

  • Grey steering wheel: LKA is in passive mode.

  • Red steering wheel: there is an error with the adaptive power steering (APS) which deactivates ALA.

  • When the LKA is off, no steering wheel icon shows on the driver display screen.

See Fig. and Fig. for examples of the LKA status in the driver display.

The LKA status indicator can appear as blue (active), grey (in passive mode; not shown), or red (an error with the adaptive power steering (APS) which deactivates ALA; not shown). The green Adaptive Cruise Control (ACC) indicator appears when the ALA feature is on.

If the driver takes their hands off the steering wheel for fifteen seconds with LKA active, an amber caution pop-up screen will appear, shown in Fig., telling the driver to return their hands to the steering wheel. Doing so will cause the pop-up to disappear.

Fig. 3,  LKA Caution Popup Screen

If the driver does not return their hands to the steering wheel within the next fifteen seconds, a red warning pop-up screen will appear and an acoustical warning will start to sound every five seconds. The warning pop-up will disappear and the acoustical warning will cease when the driver returns their hands to the wheel.

If the driver does not return their hands to the steering wheel, the warning pop-up remains. Starting at fifty-five seconds the acoustical warning will start to sound every second. At sixty-seconds this become a continuous audible warning and LKA will drop into passive mode. The warning pop-up will remain on the driver display screen until the driver places their hands on the steering wheel.

While the driver's hands are on the steering wheel, LKA engages in micro-steering adjustments to keep the vehicle in the driver's preferred lane position. The preferred lane position can be set under the Drive Time Systems menu, under Driving Systems, under Settings. Options include: offset to the right, offset to the left, or center.
