Lane Departure Prevention (LDP) system

Lane Departure Prevention (LDP) system  - Lane Departure Warning (LDW)/Prevention (LDP) system (if so equipped) - Starting and driving - Infiniti QX Owners Manual - Infiniti QX

Precautions on LDP system

► The LDP system will not steer the vehicle WARNING

► The LDP system will not steer the vehicle or prevent loss of control. It is the drivers responsibility to stay alert, drive safely, keep the vehicle in the traveling lane, and be in control of vehicle at all times.
► The LDP system is primarily intended for use on well-developed freeways or highways. It may not detect the lane markers in certain roads, weather or driving conditions.
► Using the LDP system under some conditions of road, lane marker or weather, or when you change lanes without using the lane change signal could lead to an unexpected system operation. In such conditions, you need to correct the vehicles direction with your steering operation to avoid accidents.
► When the LDP system is operating, avoid excessive or sudden steering maneuvers. Otherwise, you could lose control of the vehicle.
► The LDP system will not operate at speeds below approximately 45 MPH (70 km/h) or if it cannot detect lane markers.
► The LDP system may not function properly under the following conditions, and do not use the LDP system: During bad weather (rain, fog, snow, wind, etc.). When driving on slippery roads, such as on ice or snow, etc. When driving off-road such as on sand or rock, etc. When driving on winding or uneven roads. When there is a lane closure due to road repairs. When driving in a makeshift lane. When driving on roads where the lane width is too narrow. When driving without normal tire conditions (for example, tire wear, low tire pressure, installation of spare tire, tire chains, non-standard wheels). When the vehicle is equipped with non-original brake parts or suspension parts. When towing a trailer or other vehicle.
► If the LDP system malfunctions, it will cancel automatically. The lane departure warning light (orange) on the instrument panel will illuminate.
► If the lane departure warning light (orange) illuminates, pull off the road to a safe location and stop the vehicle. Turn the engine off and restart the engine. If the warning light (orange) continues to illuminate, have the LDP system checked by an INFINITI retailer.
► Excessive noise will interfere with the warning chime sound, and the chime may not be heard.

The functions of the LDP system (warning and brake control assist) may or may not operate properly under the following conditions:
► On roads where there are multiple parallel lane markers; lane markers that are faded or not painted clearly; yellow painted lane markers; non-standard lane markers; or lane markers covered with water, dirt, snow, etc.
► On roads where discontinued lane markers are still detectable.
► On roads where there are sharp curves.
► On roads where there are sharply contrasting objects, such as shadows, snow, water, wheel ruts, seams or lines remaining after road repairs. (The LDP system could detect these items as lane markers.).
► On roads where the traveling lane merges or separates.
► When the vehicles traveling direction does not align with the lane marker.
► When traveling close to the vehicle in front of you, which obstructs the lane camera unit detection range.
► When rain, snow or dirt adheres to the windshield in front of the lane camera unit.
► When the headlights are not bright due to dirt on the lens or if the aiming is not adjusted properly.

► When strong light enters the lane camera unit. (For example, the light directly shines on the front of the vehicle at sunrise or sunset.).
► When a sudden change in brightness occurs. (For example, when the vehicle enters or exits a tunnel or under a bridge.). While the LDP system is operating, you may hear a sound of brake operation. This is normal and indicates that the LDP system is operating properly.

LDP system operation

The LDP system provides a lane departure

The LDP system provides a lane departure warning and brake control assistance when the vehicle is driven at speeds of approximately 45 MPH (70 km/h) and above. When the vehicle approaches either the left or the right side of the traveling lane, a warning chime will sound and the lane departure warning light (orange) on the instrument panel will blink to alert the driver. Then, the LDP system will automatically apply the brakes for a short period of time to help assist the driver to return the vehicle to the center of the traveling lane. The warning and assist functions will stop when the vehicle returns to a position inside of the lane marker.

The LDP system turns on when the dynamic

The LDP system turns on when the dynamic driver assistance switch on the steering wheel is pushed when the Lane Departure Prevention is enabled in the settings menu on the center display. The LDP ON indicator light (green) on the instrument panel illuminates when the LDP system is turned on.

Automatic deactivation

Condition A:

The warning and assist functions of the LDP system are not designed to work under the following conditions:
► When you operate the lane change signal and change the traveling lanes in the direction of the signal. (The LDP system will be deactivated for approximately 2 seconds after the lane change signal is turned off.).
► When the vehicle speed lowers to less than approximately 45 MPH (70 km/h).
► When the Blind Spot InterventionTM system activates an audible warning or brake control. After the above conditions have finished and the necessary operating conditions are satisfied, the warning and assist functions will resume.

Condition B:

The assist function of the LDP system is not designed to work under the following conditions (warning is still functional):
► When the brake pedal is depressed.
► When the steering wheel is turned as far as necessary for the vehicle to change lanes.
► When the accelerator pedal is depressed while the brake control assist is provided.
► When the Intelligent Cruise Control (ICC) approach warning occurs.
► When the hazard warning flashers are operated.
► When driving on a curve at high speed. After the above conditions have finished and the necessary operating conditions are satisfied, the LDP brake control assist function will resume.

Condition C:

Under the following conditions, a beep will sound and the LDP system will be canceled automatically. The LDP ON indicator light will blink in green, and the LDP system cannot be activated:
► When the VDC system (except TCS function) or ABS operates.
► When the VDC system is turned off.
► When the SNOW mode switch is turned on.
► When the 4WD shift switch is in the 4H or 4L position (for 4WD models). Action to take: When the above conditions no longer exist, turn off the LDP system by pushing the dynamic driver assistance switch. Push the dynamic driver assistance switc

Temporary disabled status at high temperature:

If the vehicle is parked in direct sunlight under high temperature conditions (over approximately 1048F (408C)) and then the LDP system is turned on, the LDP system may be deactivated automatically. The lane departure warning light (orange) will blink. When the interior temperature is reduced, turn off the LDP system by pushing the dynamic driver assistance switch. Push the dynamic driver assistance switch again to turn the LDP system back on.

Lane camera unit maintenance

The lane camera unit 1 for the LDW/LDP

The lane camera unit 1 for the LDW/LDP system is located inside the map light cover. To keep the proper operation of the LDW/LDP systems and prevent a system malfunction, be sure to observe the following:
► Always keep the windshield clean.
► Do not attach a sticker (including transparent material) or install an accessory near the camera unit.
► Do not place reflective materials, such as white paper or a mirror, on the instrument panel. The reflection of sunlight may adversely affect the camera units capability of detecting the lane markers.
► Do not strike or damage the areas around the camera unit. Do not touch the camera lens or remove the screw located on the camera unit. If the camera unit is damaged due to an accident, contact an INFINITI retailer.
