Seat Belts and Airbags
The RDX is equipped with a sophisticated six-airbag system, which includes two front and two front side airbags, and two side curtain airbags with coverage for the front and outboard rear seats. All five seating positions in the RDX have 3-point belts and head restraints. The front seats also have load-limiting tensioners.
- The front airbags are equipped with two-stage, multiple-threshold inflators. These airbags are capable of being inflated at different rates depending on crash severity, seat belt usage and/or other factors. Frontal airbags are designed to supplement the seat belts to help reduce the likelihood of head and upper body injuries in frontal crashes.
- Sensors in the front passenger seat determine if it is empty or if the passenger is too small for the passenger’s front airbag to deploy safely, and disengage the front passenger’s front airbag, if necessary.
- The Occupant Position Detection System (OPDS) uses sensors in the front passenger seatback to determine the height and position of the passenger and will deactivate the side airbag if a child or small-statured adult leans into the side airbag deployment path.
- In a side impact, side curtain airbags deploy downward from just above the doorframes on the impacted side to help protect both front and outboard rear seat occupants.
- The seat belts include an automatic tensioning system that reacts in the first milliseconds of an impact to automatically tighten and help hold the individual in position against the seatback.
- To help prevent the automatic tensioning belt from causing undue pressure on the chest, load limiters slightly relieve belt tension, as needed, to help soften the force.
Body Structure Design
Acura utilizes Advanced Compatibility Engineering™ (ACE™) body structure to enhance occupant protection and crash compatibility in frontal crashes.
- The ACE™ design utilizes a network of connected structural elements to distribute crash energy more evenly throughout the front of the vehicle.
- This enhanced frontal crash energy management helps to reduce the forces transferred to the passenger compartment and can help to more evenly disperse the forces transferred to the other vehicle in a crash.
Vehicle Stability Assist
The Vehicle Stability Assist™ (VSA®)12 system uses an array of sensors along with ABS to minimize the dangers of oversteer or understeer.
- The system continually monitors vehicle speed, throttle position, individual wheel speeds, steering angle, lateral G-force, and yaw rate.
- When the potential for oversteer or understeer is detected, VSA will reduce the engine’s torque and use the ABS system to apply brakes to each wheel as needed to help stabilize the vehicle.
- The response is so quick that the instability may be corrected before the driver even knows it’s occurring.
Tire Pressure Monitoring System
Since an under-inflated tire impedes handling and can be a safety hazard, the Tire Pressure Monitoring System (TPMS) uses pressure sensors mounted in each wheel that send readings to a central electronic control unit. The system then evaluates whether the pressure is in an acceptable range.
- If a reading is approximately 25% below the recommended level, the RDX will alert the driver through the instrument panel light and the Multi-Information Display (MID).
- On models with the Technology Package, the problem tire will be indicated, along with the individual pressure for all four tires. The pressure display can also be accessed anytime, using the MID controls on the steering wheel.
- As useful as TPMS is, it is still recommended that you manually check your tires on a regular basis.
