Lane keeping system
When you’re on the road, the available lane keeping system can help you keep your vehicle inside of your lane.
The lane keeping system uses a camera mounted behind the windshield’s rear view mirror to monitor road lane markings and detect unintentional drifting toward the outside of a lane. If the camera detects an impending unintentional drift, the system will use the steering system and the instrument cluster display to alert and/or aid you to stay in your lane.
The lane keeping system will only become available above 40 mph (64 km/h). It will work as long as the camera can detect at least one lane marking. However, the system may not function if the camera is blocked or if there is damage to the windshield.
Holding the Wheel
When aid mode is on and the system detects no steering activity for a short period, the system will alert you to put your hands on the steering wheel. The system may also identify a light grip on the steering wheel as hands-off driving.
Using the system
Switching the System On and Off
To switch the system on, please find location of the system switch in your vehicle’s Owner Guide. The system’s on or off setting will be stored until it is manually changed again. The system can be temporarily suppressed at any time by the following intentional driver activities:
- Quick braking
- Fast acceleration
- Use of the turn signal indicator
- An evasive steering maneuver
Using the System with a MyKey
IIf the system detects a MyKey, the system will automatically turn on and default to alert mode.
Changing the Settings
To view or adjust the system’s optional settings menus, see General Information. The system will store the last-known selection for each of these settings, so you will not need to readjust them each time you turn on the system.
Adjusting the mode setting allows you to enable and disable features by choosing between alert only mode, aid only mode, or alert + aid mode.
Alert only mode — Provides a steering wheel vibration when the system detects an unintended lane departure into the zones highlighted in the diagram above.
Aid only mode – Provides an assistance steering torque input toward the lane center when the system detects an unintended lane departure into the zones highlighted in the diagram above.
A = Alert
B = Aid
Alert + Aid – Provides an assistance steering torque input toward the lane center when the system detects an unintended lane departure into one of the B zones highlighted above. If your vehicle continues drifting out of the lane and into one of the A zones, the system provides a steering wheel vibration.
Note: These diagrams illustrate general zone coverage, and they do not provide exact parameters.
The intensity setting affects the intensity of the steering wheel vibration used for the alert and alert + aid modes. This setting does not affect the aid mode. You can choose between low, medium, and high vibration intensity.
System Display Setting
When you switch on the system, an overhead graphic of a vehicle with lane markings will be visible in the information display. If you select aid mode when you switch on the system, a separate white icon will also appear, or in some vehicles, arrows will display with the lane markings. When you switch off the system, the lane marking graphics will not display. While the system is on, the color of the lane markings will change to indicate the system’s status.
Gray Lane Markings
Indicates that the system is temporarily unable to alert or aid you on the indicated side(s). This may be because:
- Your vehicle is travelling slower than the activation speed.
- The turn indicator is active.
- Your vehicle is in a dynamic maneuver.
- The lane markings in the camera field of view are poor or nonexistent.
- The camera is obscured or unable to detect outside lane markings due to environmental conditions (significant sun angles, shadows, snow, heavy rain or fog), traffic conditions (following a large vehicle that is blocking or shadowing the lane), or vehicle conditions (poor headlamp illumination).
- See Troubleshooting for additional information.
Green Lane Markings
Indicates that the system is available and ready to alert or aid you on the indicated side(s).
Yellow Lane Markings
Indicates that the system is providing or has just provided a lane keeping aid intervention.
Red Lane Markings
Indicates that the system is providing or has just provided a lane keeping alert warning.
Why is the feature unavailable, as indicated by gray lane markings, even though I can see the lane markings on the road?
- Vehicle speed outside of the operational range for the system
- Sun shining directly into the camera lens
- Quick intentional lane change
- Driving too close to the lane marking. The system will become available again as soon as the driver returns to the center of the current lane.
- Driving at high speeds in curves
- Previous feature activation occurred within the last second
- Ambiguous lane markings, such as those in construction zones
- Rapid transition from light to dark or vice versa
- Sudden offset in lane markings
- ABS or traction control activation
- Camera blockage due to dirt, grime, fog, frost or water on the windshield
- Driving too close to the vehicle in front of you
- Transitioning from no lane markings to lane markings or vice versa
- Standing water on the road
- Faint lane markings, such as partial yellow lane markings on concrete roads
- Lane width too narrow or too wide
- Camera was not calibrated after a windshield replacement
- Driving on tight or uneven roads
Why doesn’t the steering redirect the vehicle as expected in the aid or aid + alert mode?
- High cross winds
- Large road crown
- Rough roads, grooves or shoulder drop offs
- Heavy and/or uneven loading of the vehicle or improper tire inflation pressure
- The suspension has been modified or the tires have been exchanged, for example, to replace them with snow tires
Lane Keeping System does not control steering. Driver Assist features are supplemental and do not replace the driver’s attention, judgment and need to control the vehicle.
They system may not be able to function in cold and severe weather conditions, or if the sensor becomes blocked. Rain, snow, spray and large contrasts in lighting can all limit sensor performance. Depending on road conditions, the system will not operate if the sensor cannot track the road lane markings.
Do not carry out windshield repairs in the immediate area surrounding the sensor.
