Seat Belts and Airbags
Seat belts are the first line of defense in a collision. That’s why all ILX seating positions have 3-point belts and head restraints. The front seats also have a load-limiting tensioner system and each airbag features a highly sophisticated deployment system.
- In the first milliseconds of a sufficient impact, tensioners automatically tighten the front belts to help hold the occupant 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.
- 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 will disengage the front passenger’s front airbag, if necessary.
- In the event of a moderate-to-severe side impact, the SmartVent™ front side airbag inflates to help protect the driver’s or front passenger’s upper torso.
The ILX has several features addressing child safety, from sophisticated airbag sensors to anchors that secure child seats.
- 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.
- All windows and the moonroof have an auto-reverse feature that is designed to prevent them from closing if a finger or other obstacle is encountered.
Body Structure Design
To enhance occupant protection and crash compatibility in frontal collisions, the ILX features next generation Advanced Compatibility Engineering™ (ACE™) body structure.
- The ACE™ design utilizes a network of connected structural elements to distribute crash energy more evenly throughout the front of the vehicle.
- This new generation ACETM incorporates extra braces at the front corners to absorb and distribute impact energy from narrow off-set collisions in which a small portion at one side of the front end must absorb the collision forces.
- The outer braces are designed to transfer impact load toward the center of the frame where the energy can be distributed around the cabin area more evenly.
- 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 other vehicles in a crash.
ILX disc brakes are complemented by several sophisticated electronic systems that enhance stopping performance in almost any circumstance.
- The anti-lock braking system (ABS) helps you retain steering control when braking heavily, by preventing the wheels from locking up while still allowing them to achieve maximum level of stopping.
- The Electronic Brake Distribution system uses the ABS system to orchestrate braking power among the four wheels—depending on their load—to help optimize braking effectiveness.
- The Brake Assist system detects emergency braking from the driver by monitoring the speed at which the brake pedal is depressed and stepping in to ensure the ABS system is activated. The system terminates immediately upon release of the brake pedal.
Vehicle Stability Assist
A standard feature that makes every driver a better driver. The Vehicle Stability Assist™ (VSA®)12 system uses an array of sensors, along with ABS to reduce the dangers of oversteer or understeer.
- VSA® 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, the VSA® modulator reduces the engine’s torque and applies brakes to each wheel (as needed) to help stabilize the vehicle.
- VSA® response is so quick that instability may be corrected before the driver even knows it’s occurring.
Collision Mitigation Braking System™ (CMBS™)
To help reduce the likelihood or severity of a frontal impact, the Advance Package features the Collision Mitigation Braking System™ (CMBS™)61.
- Powered by a combination of radar transmitter and forward-facing camera, the CMBS™ determines the distance and closing speed of detected objects that lie directly ahead.
- If you do not take action to reduce speed, the CMBS™ automatically tugs the seat belt and begins light braking.
- When the system senses that a frontal collision is unavoidable even if no prior alerts have been given, the front seat belts tighten and strong braking is automatically applied to help reduce the impact velocity and collision force.
- The goal of the CMBS™ is to alert the driver to apply the brakes. While the system assists, it is not expected to avoid a collision on its own.
Road Departure Mitigation System
The highly capable, road-hugging ILX prefers pavement.
- While the Lane Keeping Assist uses a camera to identify lane markers such as painted lane lines, Botts Dots and cat eye markers, the Road Departure Mitigation System can identify objects such as trees or parked cars which would indicate spaces beyond the side of the road.
- When the system detects the ILX is about to leave the road, it warns the driver with an MID warning message, an amber head-up warning and a tightening of the seat belt.
- The system then uses the active steering function of the Lane Keeping Assist system along with the vehicle’s autonomous braking capability to guide the ILX back into its detected lane.
Lane Keeping Assist System
It’s the best kind of backseat driver. Using a forward-facing camera mounted above the inside rear view mirror, the Lane Keeping Assist System (LKAS)59 works proactively to keep the ILX inside a detected lane.
- If you steer the ILX out of a detected lane without signaling your intention, the system will gently tug the steering wheel and help guide the car back to the center of the lane.
- Though the system initiates a slight tug, the driver can easily hold course as the system will not take control of the wheel.
- On straight or mildly curving roads, LKAS works to keep the car in the center of the detected lane.
- The system will not steer the car indefinitely. If it senses no steering input from the driver for a certain period of time, the system presents a message instructing the driver to begin steering again.
Adaptive Cruise Control
Conventional cruise control has always been welcome on long highway trips but is of little use on an urban driver’s daily commute. Available Adaptive Cruise Control (ACC) allows you to set a desired speed but also maintain a desired interval to the car ahead so you enjoy the benefits of cruise control in light traffic.
- While cruising, engage the ACC and the system prompts you to select a short, medium, long or extra-long interval to the vehicle ahead.
- Once speed is set (between 25 and 90 mph), you can raise or lower it with the steering-wheel controls. Your speed setting is revealed on the MID.
- At speeds below the set speed, ACC maintains the set interval from the car ahead by modulating the throttle and applying moderate braking where appropriate.
Blind Spot Information System
The Blind Spot Information (BSI) system20 is your second pair of eyes during lane changes.
- If the system detects a vehicle in the adjacent lane’s “alert zone”, an indicator appears on that side’s windshield pillar and also on the MID screen.
- If the driver activates the turn signal in the direction of a vehicle that has been detected, the pillar indicator on the corresponding side flashes and a warning beep will sound.
- So the indicators don’t come on at stoplights, when parking or when traveling in stop-and-go traffic, the system is only active when the ILX is traveling over 6 mph.
Rear Cross Traffic Monitor
Whether backing out of parking space or onto a busy street, the ILX has your back.
- Sensors located near the rear corners of the car can detect approaching vehicles from either side in parking lots, driveways or streets.
- The monitor is particularly useful when other parked vehicles hinder your side-to-side vision.
- With the multi-view rear camera50 in Normal or Wide mode, the driver is alerted to approaching vehicles by an audible chime and amber arrows in the rear camera monitor.
If momentarily distracted, two state-of-the-art warning systems can alert you to potentially dangerous conditions. Using a camera mounted between the windshield and the rearview mirror, the Lane Departure Warning (LDW) system56 sounds an alert when the ILX unintentionally leaves a detected lane. The Forward Collision Warning (FCW) system55—using both visual and audible warning—alerts you to a potential collision with a vehicle detected ahead.
- At speeds of 45 mph and above, the LDW system looks for painted lines, reflectors or other demarcations of lane division. If the ILX begins to exit a detected lane when the turn signal has not been engaged, the system gives an audible alert accompanied by a Lane Departure message on the MID indicating the side of the lane being crossed. These alerts will disengage when the car returns to the center of the lane or the correct turn signal is activated.
- A button located to the left of the steering column easily disengages LDW.
- FCW can detect vehicles directly in front of the ILX. If the distance between the two vehicles is diminishing, the system compares the vehicles’ current speeds to determine if a collision may occur.
- To alert the driver to apply the brakes, FCW issues a beeping sound and flashes an amber “Brake” message in the Multi-Information Display. Advance Package-equipped models also project an amber warning image onto the windshield.
- To avoid unnecessary warnings, the FCW will not operate at speeds below 10 mph.
Tire Pressure Monitoring System
Since an under-inflated tire impedes handling and can be a safety hazard, the Tire Pressure Monitoring System (TPMS) uses a sensor to determine if a tire’s pressure is outside an acceptable range.
- Pressure sensors in each wheel send readings to a central electronic control unit that evaluates whether the pressure is within an acceptable range. If a reading is significantly below the recommended level, the ILX alerts you on the Multi-Information Display (MID). The problem tire (along with the individual pressure for all four tires) is indicated.
- As useful as TPMS is, it is still recommended that you manually check your tires on a regular basis.
Like every Acura model, the ILX 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.
