Lane Keeping System (Lane Assist)
Introduction
Lane Assist helps the driver to stay in a
lane, within the system limitations. This
function is not suitable for, and not
designed for, autonomously keeping
your vehicle in a lane.
If the system detects that the vehicle is coming too close to a lane marker, Lane Assist warns the driver with corrective steering. The driver can override the
corrective steering at any time.
Speed range
Lane Assist is ready to take control (active system status) when a lane marking is detected within the system limits above approximately 60 km/h (approximately
35 mph).
WARNING
Lane Assist is not a replacement for the driver's attention and works only within the system limitations. Lane Assist cannot detect all driving situations and may
not react, may react with a delay, or may react in a way that is not desired. If you are careless, there is a risk of accidents, serious injuries and death.
Always stay attentive and do not rely solely on the system. The driver is always responsible for keeping the vehicle within the lane.
Observe the system limitations ⇒ Lane Assist system limitations.
Always adapt your speed and distance to vehicles driving ahead based on the visual, weather, road, and traffic conditions.
Always keep your hands on the steering wheel so that you are prepared to steer at any time.
Override immediately by steering if the system intervenes when it should not.
Pay attention to indicators in the instrument cluster display and respond to the prompts accordingly when the traffic situation allows.
Lane Assist system limitations
Please read the introductory information and heed the Warnings and Notice ⇒
Introduction.
Limits of the sensor system
Lane Assist detects lane markings with the camera behind the windshield.
Observe the limits of the camera ⇒ Limits of the sensor system . Always be attentive and intervene yourself if necessary!
Lane markings not detected or not correctly recognized
Lane Assist does not correctly detect all lane markings. If lane markings are not detected or if markings are incorrectly detected as lane markings, Lane Assist may
148
fail to intervene when it should or may intervene when not desired. In addition to the situations specified in the camera limitations, this may also occur in the
following situations, among others:
If lane markings are not present.
When the driving style is very dynamic.
When not on highways or well-developed roads.
On poor road surfaces, road structures or objects.
In the event of reflections or dazzling effects.
Always be attentive and intervene yourself if necessary by overriding unwanted interventions by the system immediately. Temporarily switch off Lane Assist if
required.
Lane Assist not available
Lane Assist is not available under the following conditions (inactive system status):
The vehicle speed is less than around 55 km/h (around 30 mph).
Lane Assist has not detected a lane marking.
If lanes and curves are too narrow.
Temporarily, when the driving style is very dynamic.
When the turn signals are switched on before a manual lane change.
When the driver oversteers during a system intervention.
When there is no reaction from the driver to a driver intervention prompt.
Driving with Lane Assist
Please read the introductory information and heed the Warnings and Notice ⇒
Introduction.
Switching on and off
You can view the switched on condition of Lane Assist in the Infotainment system. You can also switch Lane Assist on and off there.
1. Open the Assistance systems menu.
2. Switch Lane Assist on or off in the corresponding submenu.
If there is a system malfunction, Lane Assist may switch off automatically.
Displays
Fig. 93 In the instrument cluster display: displays of Lane Assist
Grey line: lane marking detected. The system is not ready to monitor on the indicated side.
Yellow line: Lane marking detected. The system is monitoring on the indicated side.
White line: Lane marking detected. The system is ready to monitor on the indicated side.
Depending on the vehicle equipment, further details about lane marking, such as broken road markings, may also be shown on the instrument cluster display.
One of the following indicator lights will light up, depending on the driving situation:
149
System active and ready to control.
System in operation (corrective steering intervention).
If the indicator light does not light up, Lane Assist is not ready for operation on both sides (inactive system status) or is switched off.
If Travel Assist is actively controlling, there will not be any steering intervention and no Lane Assist display.
Driver intervention request
If there is no steering activity, Lane Assist prompts you to drive in the center of your lane with an indicator in the instrument cluster display and warning chimes.
If you do not respond accordingly, Lane Assist becomes inactive.
Depending on the vehicle equipment, semi-automatic vehicle control in a medical emergency (Emergency Assist) is activated when Emergency Assist is switched
on in the Infotainment system.
Independently of steering activity, you are also prompted by an indicator on the instrument cluster display and by a warning chime to drive in the middle of the lane
the corrective steering intervention takes a long time.
Steering wheel vibration
The following situation may cause the steering wheel to vibrate:
A lane is no longer detected during a sharp corrective steering intervention by the system.
In addition, you can select the Vibration or Steering wheel vibration option in the Assistance systems menu in the Infotainment system. If you select this option, the
steering wheel will vibrate if Lane Assist is active and you drift onto a road lane marking that the system has detected.
