Nissan ALTIMA 2022 Intelligent Forward Collision Warning and Intelligent Driver Alertness 

The Intelligent Forward Collision and Driver Alertness System, a comprehensive safety package that dramatically improves both collision avoidance and driver attentiveness, is new for the 2022 Nissan Altima. This cutting-edge technology combines Automatic Emergency Braking, which can apply the brakes to lessen or prevent an accident if the driver doesn’t respond in time, with Forward accident Warning, which scans the road ahead for possible Nissan Altima collision light risks and issues timely warnings. Furthermore, the Driver Alertness System keeps an eye on the driver’s actions and sends out alerts to encourage a break if it notices any indications of fatigue or inattention. When combined, these features demonstrate the Altima’s dedication to safety by offering crucial protections and encouraging a higher degree of driver awareness for a safe and assured driving experience.

INTELLIGENT FORWARD COLLISION WARNING (I-FCW)

WARNING
Failure to follow the warnings and instructions for proper use of the I-FCW system could result in serious injury or death. The I-FCW system can help warn the driver before a collision occurs but will not avoid a collision. It is the driver’s responsibility to stay alert, drive safely, and be in control of the vehicle at all times. The I-FCW system can help alert the driver when there is a sudden braking of a second vehicle traveling in front of the vehicle ahead in the same lane.

The I-FCW system uses a radar sensor 1O located on the front of the vehicle to measure the distance to the vehicle ahead in the same lane.

1. The vehicle ahead detection indicator
2. AEB with Pedestrian Detection system warning light

I-FCW SYSTEM OPERATION
The I-FCW system operates at speeds above approximately 3 mph (5 km/h). If there is a potential risk of a forward collision, the I-FCW system will warn the driver by blinking the vehicle ahead detection indicator and sounding an audible alert.

TURNING THE I-FCW SYSTEM ON/OFF

INTELLIGENT DRIVER ALERTNESS (I-DA)

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

• The I–DA system is only a warning to inform the driver of a potential lack of driver attention or drowsiness. It will not steer the vehicle or prevent loss of control.
• The I–DA system does not detect and provide an alert of the driver’s lack of attention or fatigue in every situation.
• it is the driver’s responsibility to:
  • stay alert,
  •  drive safely,
  • keep the vehicle in the traveling lane,
  •  be in control of the vehicle at all times,
  •  avoid driving when tired,
  • avoid distractions (texting, etc.).

The I–DA system helps alert the driver if the system detects a lack of attention or driving fatigue. The system monitors driving style and steering behavior over a period of time, and it detects changes from the normal pattern. If the system detects that driver attention is decreasing over a period of time, the system uses audible and visual warnings to suggest that the driver take a break.
