Nissan Murano: Automatic Emergency Braking (AEB) (if so equipped) / AEB system limitations
WARNING
Listed below are the system limitations
for the AEB system. Failure to operate
the vehicle in accordance with these
system limitations could result in serious
injury or death.
- The AEB system cannot detect all vehicles
under all conditions.
- The radar sensor does not detect the
following objects:
- Pedestrians, animals or obstacles
in the roadway.
- Oncoming vehicles.
- Crossing vehicles.
- The radar sensor has some performance
limitations. If a stationary vehicle
is in the vehicle’s path, the AEB
system will not function when the vehicle
is driven at speeds over approximately
50 mph (80 km/h).
- The radar sensor may not detect a vehicle
ahead in the following
conditions:
- Dirt, ice, snow or other material
covering the radar sensor.
- Interference by other radar
sources.
- Snow or road spray from traveling
vehicles.
- If the vehicle ahead is narrow (e.g.,
motorcycle).
- When driving on a steep downhill
slope or roads with sharp curves.
- In some road or traffic conditions, the
AEB system may unexpectedly apply
partial braking. When acceleration is
necessary, continue to depress the
accelerator pedal to override the
system.
- Braking distances increase on slippery
surfaces.
- The system is designed to automatically
check the sensor’s functionality,
within certain limitations. The system
may not detect some forms of obstructions
of the sensor area such as
ice, snow, stickers, etc. In these cases,
the system may not be able to warn
the driver properly. Be sure that you
check, clean and clear the sensor area
regularly.
- Excessive noise will interfere with the
warning chime sound, and the chime
may not be heard.

Perform the following steps to turn the AEB
system on or off.
Press the button until
“Settings”
displays in the vehicle information display
and then press the OK button...
Condition A
When the radar sensor picks up interference
from another radar source, making it
impossible to detect a vehicle ahead, the
AEB system is automatically turned off...
