The ZDX disc brakes are backed up by several sophisticated electronic systems to provide you with enhanced braking abilities under almost any circumstance.
- The anti-lock braking system (ABS) helps you retain steering control in emergency braking by preventing the wheels from locking up, while still letting them achieve their maximum level of stopping power.
- The Electronic Brake Distribution (EBD) system uses the ABS system to direct braking power among the four wheels, depending on the vehicle load, to help optimize braking effectiveness.
- The Brake Assist system detects emergency braking by the driver by monitoring the speed at which the brake pedal is depressed and stepping in to ensure the ABS system is activated—terminating immediately upon release of the brake pedal.
Vehicle Stability Assist
The Vehicle Stability Assist™ (VSA®)12 system monitors stability factors to detect oversteer or understeer, and if detected, VSA uses a number of the ZDX systems to remediate the problem.
- The system continually monitors vehicle speed, throttle position, individual wheel speeds, steering angle, lateral G-force, and vehicle yaw rate.
- If potential oversteer or understeer is detected, the system will first use the Super Handling All-Wheel Drive™ (SH-AWD®) to redirect power among the front wheels and each of the rear wheels to maintain stability.
- If using SH-AWD is insufficient, the system will reduce engine torque and use the anti-lock braking system (ABS) to apply brakes to each wheel as needed to help stabilize the vehicle.
- In all cases, VSA 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 up to an acceptable range.
- If a reading is approximately 25% below the recommended level, the ZDX will alert the driver through the Multi-Information Display (MID) located on the instrument panel.
- The under-inflated tire will be indicated, along with the individual pressure, for all four tires.
- The pressure display can be accessed anytime using the MID controls on the steering wheel.
- As useful as TMPS is, it is still recommended that you manually check your tires on a regular basis.
Forward Collision Warning
The Forward Collision Warning system (FCW) alerts you to a potential collision with a vehicle ahead, using both visual and audible warnings.
- The system can detect vehicles directly in front of the car, using a camera mounted between the windshield and the rearview mirror. If the distance to that vehicle is diminishing, the system compares the vehicles’ current speeds to determine if a collision may occur.
- To alert the driver to apply the brake pedal, an amber “Brake” message will flash in the Multi-Information Display, and a series of beeps will be emitted.
- To avoid unnecessary warnings, the system will not operate at speeds below 10 mph.
- Drivers can adjust the distance at which the alerts will be triggered by accessing the personal settings section through the Multi-Information Display.
Lane Departure Warning
The Lane Departure Warning system (LDW) is designed to alert the driver when the vehicle unintentionally leaves a clearly designated lane.
- Using the same camera as the FCW system, the system looks for lane markings and, once they’re detected, it can determine if the vehicle is about to leave its lane without turn signals engaged.
- The system engages at speeds of 45 miles per hour and above on relatively straight or slightly curved roads.
- If the vehicle begins to cross a lane marking, and the turn signal has not been engaged, the system will flash the LDW indicator on the instrument panel, and an amber Lane Departure message on the Multi-Information Display will sound a series of beeps, alerting the driver to either return to the lane or activate the turn signal.
- The system can be disengaged with the LDW button that’s located to the left of the steering column. Upon restarting the car, the system will always default to the “On” position.
Advanced Compatibility Engineering
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 vehicles in a crash.
The ZDX is equipped with a sophisticated 6-airbag system, which includes two front airbags and two front-side airbags, and two side curtain airbags that provide coverage for the front and outboard rear seats.
- The front airbags are equipped with two-stage, multiple-threshold inflators. One or both airbags will be deployed only in the event of a sufficient frontal impact. If deployed, 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. The system will deactivate the passenger’s front-side airbag if a child or small-statured adult is leaning into the 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.
Seat Belts & Active Front Head Restraints
All five seating positions in the ZDX have 3-point belts and head restraints. The front seats have load-limiting tensioners and active head restraints.
- Tensioners react in the first milliseconds of a sufficient impact to automatically tighten the belts and help hold the individual in position against the seatback.
- To help prevent the tensioners from causing undue pressure on the chest, load limiters slightly relieve belt tension, as needed, to help soften the force.
- In a rear-end collision, when the front seat occupant’s body is pushed against the seatback, the pressure forces the head restraint upward and forward to reduce the gap between the occupant’s head and the head restraint.
- Impact forces on the neck and spine are diminished, helping reduce the likelihood of whiplash injuries.
The ZDX has several features addressing child safety, from sophisticated airbag sensors to anchors that secure child seats.
- The Occupant Position Detection System (OPDS) utilizes sensors in the front passenger's seatback to detect if the occupant is a child or small-statured adult. If such an occupant is leaning into the side airbag’s deployment path, the side airbag will be deactivated until they resume a more upright position.
- All windows and the moonroof have an auto-reverse feature that can reverse their closing if an obstacle is encountered.
- LATCH (Lower Anchors and Tethers for CHildren) anchors plus upper-tether anchors in the rear seat allow LATCH-compatible child seats to be installed in the outboard positions without the use of seat belts.
Like every Acura model, the ZDX comes equipped with a security system. In the event of a break-in, the following events will occur:
- The ignition will be disabled.
- The horn will sound.
- The lights will flash.
