Basic Vehicle Technologies 1: Safety
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 belt to be installed with the seat belt without using a locking clip
What does the LATCH system do?
Allows placement of LATCH-compatible child resistant seats in the rear seats
Which of the following are features of the air bag system?
Capacitor stores power to energize air bags if battery fails before deployment Vent holes help air bags absorb impact energy and deflate after deployment Air bags are equipped with gold plated connectors to prevent corrosion
What are the two aspects of safety for insurance institute testing?
Crash avoidance and mitigation Crashworthiness
What's the benefit of an energy-absorbing steering column?
Designed to compress during certain frontal impacts to help absorb energy
What do high-strength side-door guard beams do?
Help add protection for the passenger compartment in certainty side impacts
How does Nissan's Brake Override Technology improve safety?
If both brake and accelerator pedals are pressed, brake pedal takes precedence
How does 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 are the three basic phases of Nissan Intelligent Safety Shield Technologies?
Monitor Protect Respond
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 in a position offset from the vehicle Obstacles with a soft outer surface that may absorb a sound wave, such as a snowbank
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 Helps Compensate for oversteer or understeer by controlling brake pressure Enhances performance in emergency maneuvers
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
What is the primary restraint system in every vehicle?
Seat Belts
Which components are part of Vehicle Dynamic Control?
Steering Angle Sensor Brake Pressure Sensor Yaw rate/lateral g-sensor Four Wheel-speed sensor
During manufacturing testing, what best describes occupant kinematics?
The movement of occupants under crash conditions
What does Automatic Emergency Braking (AEB) use the sensor in front of the vehicle to monitor for?
The relative velocity and distance to the vehicle immediately ahead
Why are air bags called a Supplemental Restraint System (SRS)?
They are designed to be used in conjunction with a seat belt
What is the function of seat belt pretensioners?
Tighten the front seatbelts during impact to help provide better energy dissipation
What does the Traction Control System do?
Uses wheel speed sensors from ABS to detect a loss of traction Senses wheel spin and automatically reduces power and/or applies the brakes
What action(s) can Rear Cross Traffic Alert (RCTA) take if it detects other vehicles approaching from either side when you are backing up?
Visual warning flashes on the side that the other vehicle is approaching them Audible warning sounds once
