Nissan Pathfinder: Starting and driving - Lane Departure Warning (LDW)

Basic information

WARNING Failure to follow the warnings and instructions for proper use of the LDW system could result in serious injury or death.

• This system is only a warning device to inform the driver of a potential unintended lane departure. It will not steer the vehicle or prevent loss of control. It is the driver's responsibility to stay alert, drive safely, keep the vehicle in the traveling lane, and be in control of the vehicle at all times.

The LDW system will operate when the vehicle is driven at speeds of approximately 37 mph (60 km/h) and above, and only when the lane markings are clearly visible on the road.

The LDW system monitors the lane markers on the traveling lane using the camera unit A located above the inside mirror.

The LDW system warns the driver that the vehicle is beginning to leave the driving lane with an indicator and a steering wheel vibration.

LDW system operation

For vehicles with the 7 inch (18 cm) display

For vehicles with the 12.3 inch (31.2 cm) display

The LDW system provides a lane departure warning function when the vehicle is driven at speeds of approximately 37 mph (60 km/h) and above and the lane markings are clear. When the vehicle approaches either the left or the right side of the traveling lane, the steering wheel will vibrate and the LDW indicator on the instrument panel will blink to alert the driver.

The warning function will stop when the vehicle returns inside of the lane markers.

The strength of the steering wheel vibration can be changed in the settings menu of the vehicle information display.

How to enable/disable the LDW system

LDW system limitations

WARNING Listed below are the system limitations for the LDW system. Failure to follow the warnings and instructions for proper use of the LDW system could result in serious injury or death.

• The system will not operate at speeds below approximately 37 mph (60 km/h) or if it cannot detect lane markers.
• Do not use the LDW system under the following conditions as it may not function properly:
  • During bad weather (rain, fog, snow, etc.).
  • When driving on slippery roads, such as on ice or snow.
  • When driving on winding or uneven roads.
  • When there is a lane closure due to road repairs.
  • When driving in a makeshift or temporary 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 you are towing a trailer or other vehicle.
• The system may not function 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 the 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 LDW system could detect these items as lane markers.)
  • On roads where the traveling lane merges or separates.
  • When the vehicle's 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, dirt or an object 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.)

System temporarily unavailable

If the vehicle is parked in direct sunlight under high temperature conditions (over approximately 104ºF [40ºC]) and then started, the LDW system may be deactivated automatically and the following message will appear in the vehicle information display: "Unavailable: High Cabin Temperature." When the interior temperature is reduced, the LDW system will resume operating automatically.

The LDW system is not designed to warn under the following conditions:

• When you operate the lane change signal and change traveling lanes in the direction of the signal. (The LDW system will become operable again approximately 2 seconds after the lane change signal is turned off.)
• When the vehicle speed lowers to less than approximately 37 mph (60 km/h).

After the above conditions have finished and the necessary operating conditions are satisfied, the LDW functions will resume.

System malfunction

If the LDW system malfunctions, it will cancel automatically and "Not Available System Malfunction" will appear in the vehicle information display. If "Not Available System Malfunction" appears in the vehicle information display, pull off the road to a safe location and stop the vehicle. Place the shift position in the P (Park) position and the ignition switch in the OFF position and restart the engine/motor. If "Not Available System Malfunction" continues to appear in the vehicle information display, have the system checked. It is recommended that you visit a NISSAN dealer for this service.

System maintenance

The lane camera unit 1 for the LDW system is located above the inside mirror. To keep the proper operation of the LDW system 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 unit's 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, it is recommended that you visit a NISSAN dealer.
