BASIC VEHICLE TECHNOLOGIES 1: SAFETY
What action(s) can Rear Cross Traffic Alert (RCTA) take if it detects other vehicles approaching from either side when you are backing up?
-Audible warning sounds once -Visual warning flashes on the side that the other vehicle is approaching from
Which components are part of Vehicle Dynamic Control?
-Brake pressure sensor -Steering angle sensor -Four wheel-speed sensors -Yaw rate/lateral g-sensor
What do high-strength side-door guard beams do?
Help add protection for the passenger compartment in certain side impacts
What is the primary restraint system in every vehicle?
Seat belts
During manufacturer testing, what best describes occupant kinematics?
The movement of occupants under crash conditions
What is the function of seat belt pretensioners?
Tighten the front seat belts during impact to help provide better energy dissipation
What are the two aspects of safety for insurance institute testing?
-Crashworthiness -Crash avoidance and mitigation
Rear Automatic Braking (RAB) uses sonar to help detect large stationary objects behind the vehicle when backing up, but what objects may not trigger the system to engage?
-Obstacles high off the ground -Obstacles with a soft outer surface that may absorb a sound wave, such as a snowbank -Obstacles in a position offset from the vehicle
What does Zone Body Construction do?
-Provides a reinforced passenger compartment that resists deforming -Divides the vehicle into three zones
What are the benefits of Vehicle Dynamic Control?
-Provides improved control on slippery road surfaces -Enhances performance in emergency avoidance maneuvers -Helps compensate for oversteer or understeer by controlling brake pressure
What are the benefits of using seat belts?
-Reduces likelihood of making contact with interior components in a crash -Best single protection device throughout range of all possible collisions CORRECT!
What does the Traction Control System do?
-Senses wheel spin and automatically reduces power and/or applies the brakes -Uses wheel speed sensors from ABS to detect a loss of traction INCORRECT!
What are the three basic phases of Nissan Intelligent Safety Shield Technologies?
-respond -monitor -protect
What can prevent Intelligent Lane Intervention (I-LI) from activating even when it detects vehicle movement out of a lane with detectable lane markings?
A turn signal has been activated
Compared to Top Safety Pick criteria, what additional qualifier is needed for a vehicle to earn a Top Safety Pick + designation in Insurance Institute for Highway Safety (IIHS) testing?
Acceptable or good headlight rating
What is the function of ALR (Automatic Locking Retractor) mode for seat belts?
Allows a child safety seat to be installed with the seat belt without using a locking clip
What does the LATCH system do?
Allows placement of LATCH-compatible child restraint seats in the rear seats
What's the benefit of an energy-absorbing steering column?
Designed to compress during certain frontal impacts to help absorb energy
What is the purpose of vehicle crumple zones?
Help absorb impact energy, reducing the risk of injury to passengers
How does Nissan's Brake Override Technology improve safety?
If both brake and accelerator pedals are pressed, brake pedal takes precedence
How does the Traction Control System detect a loss of traction?
It uses the four wheel speed sensors of the Anti-lock Braking System
What is the main determining factor for air bag deployment?
Measured deceleration
What does Automatic Emergency Braking (AEB) use the sensor in the front of the vehicle to monitor for?
The relative velocity and distance to the vehicle immediately ahead
