2005 Acura RL Interior Part 1



The RL interior is designed to integrate richly elegant luxury and cleanly efficient design, to create an environment in tune with the car's clearly defined sporting character. At the same time, the interior makes the most advanced technology ever built into an Acura easy to use and intuitive to operate. Careful integration of the many advanced systems ensures that they add to the driver's comfort, control and understanding of the driving situation, and never detract from it. The finest interior materials and exacting attention to detail and finish highlight the quiet interior. Stylish and highly supportive perforated leather-trimmed seats are designed to provide a sporty, yet refined driving experience.

The RL feature list is now even more comprehensive, with a standard Acura/Bose DVD-Audio system that delivers surround sound in all seating positions, and XM® Satellite Radio. The Acura Navigation System with Voice Recognition is standard, and features a large 8-inch screen. The all-new AcuraLink™ satellite communication system incorporates the first ever U.S. delivery of real time in-car traffic information.

With the Acura HandsFreeLink™ system that lets the driver dial a Bluetooth-enabled mobile phone by voice, OnStar® service, and Satellite-based AcuraLink™ that allows communication between the RL owner and Acura, there's never been a more "connected" vehicle than the RL. The RL is also the first Acura equipped with the Keyless Access System, which allows owners to lock and unlock doors, open the trunk, and start the car without having the keyless remote in the hand.

The quality of materials, fit and finish have received close attention to reflect the spirit of the new RL. Genuine curly maple wood trim sweeps across the instrument panel. The large, bright navigation system display is positioned up high, in the center of the instrument panel within easy line of sight of the driver and passenger. Below the navigation system screen, the satin metal finish of the climate, audio and navigation controls has a clean, technical look.


Acura interior design has always made intuitive functionality a priority. All important systems and controls are within easy reach of the driver. The systems used most frequently-audio, cruise control, HandsFreeLink™, Satellite-Linked Navigation System and Multi-information display-have controls positioned on the steering wheel. The main instrumentation is easy-to-read analog, supplemented with digital and graphic displays. Even though the RL gives its driver access to many electronic features and conveniences, the interface is simple and welcoming. Sight lines are clear with important items placed within easy view.

Typical of Acura interior design, the soft-touch switchgear of the RL is engineered to deliver a quality feel and positive action. Helpful features make driving easier, like power rearview mirrors that can be set to automatically tilt-down when reverse is engaged to make parking simpler. There is also a new bottom-hinged throttle pedal with a more linear feel and natural motion. A large dead pedal in the driver's foot well provides extra support for the driver in aggressive driving.


The leather wrapped steering wheel incorporates the most commonly used controls, allowing the driver to keep their hands on the wheel while using them. Audio system controls are on the upper left spoke, while cruise control buttons are on the right upper spoke. The lower left spoke is reserved for navigation system controls, including a push-to-talk button to activate the voice recognition system which provides voice control of the navigation system, as well as many climate control and audio system features.

Also on the left, between the spokes, are controls for HandsFreeLink™, while on the right between the spokes are controls for the Multi-information display. Tucked out of view, but within fingertip reach, is a pair of paddles that upshift and downshift the Sequential SportShift transmission when it is in manual mode.


Most of the commonly used electronic functions have dedicated controls positioned on the instrument panel or on the steering wheel. Voice control of navigation, climate control, audio and communications functions is likewise available, while a Interface Dial positioned just ahead of the front center console-mounted shift lever provides another avenue of control. The Interface Dial is rotated and rocked like a joystick to select among function menus displayed on the navigation screen. A push of the controller selects the highlighted item. Functions controlled by the Interface Dial include:

  • Audio
  • Navigation
  • Climate Control System
  • AcuraLink™ satellite communications system


Given the performance capabilities and luxury mission of the RL, its passenger seating required extensive engineering development. The front seats in particular had to blend long-trip comfort with the secure lateral support needed, given the cornering potential afforded by the advanced SH-AWD system. As a result, the front seats are taller and wider than in the past, which also allows them to accommodate a wide range of body types. The RL seat cushions use a special urethane with high damping coupled with a new wider "S" spring design for better support of the urethane padding. These features work together to reduce the road and engine vibration transmitted to the passenger.

The driver's seat is 8-way power adjustable and includes a power-adjustable lumbar support mechanism. The smooth shape of the articulated lumbar mechanism matches the human spinal curvature to provide solid support for the torso and pelvis. All driver's seat power adjustments except power adjustable lumbar support are included in the Keyless Access System, which stores a pair of user profiles, one for each of the two fobs that come with the RL.

The front passenger seat is 4-way power adjustable with lumbar support. In the rear seat area, the outer seating positions are carefully engineered-complete with side bolsters-to combine luxurious comfort on long trips with solid lateral support.

In front, 4-way headrests are adjustable for height and tilt. In back, all of the three headrests have a remote retractable feature that allows the driver to lower them with a touch of an overhead button for better rearward visibility when there are no rear-seat passengers. When carrying rear passengers, the headrests can be raised manually for use.


A highly functional instrument panel gives the RL driver instant access to critical information. It also provides important vehicle information via an LCD Multi-information display positioned in the lower speedometer face. The Multi-information display shows vehicle mileage and trip mileage. Controls positioned at the 4 o'clock position of the steering wheel hub allow the driver to cycle the display through multiple screens of information.

Trip computer functions include average and instantaneous fuel economy, average speed, fuel range, and elapsed time. The system also can display outside air temperature, engine oil life as a percentage, SH-AWD torque distribution, and tire pressures. The Maintenance Minder System alerts the RL driver of upcoming maintenance needs via the Multi-information display ; should a fault occur with the vehicle, warning information also appears (see Engine section for more information).


The theme of efficient driver control and easy to read components carries on after dark in the RL. The analog instruments are LED backlit, with high-contrast markings and a subdued blue accent hue. The progressive self-illuminating gauge package gives the car a "welcoming" feel. When the door is first opened, the instrument lighting comes to life, and then brightens progressively to 100 percent when the ignition is switched on. The illuminated instrument needles and enunciator lights then come alive, indicating that the car is ready to go. At the end of the drive, the instrument lighting dims progressively.

All the interior switches are illuminated to make them easy to locate at night, including those on all four doors and the steering wheel. In addition to front and rear overhead interior lights and map lights, the RL also has a complement of low-level interior ambient cabin lighting. Blue front and rear low-level ambient lighting in the ceiling illuminates the front center console and the rear flip-down armrest. The front foot wells also have low-level ambient lighting that brightens substantially when the doors are opened.

Front and rear interior door handle areas are also illuminated to make them easy to find, and the front door storage compartments, glove compartment and the front armrest compartment are all internally illuminated. All four doors have courtesy lights that are illuminated when the doors are open. The RL interior lights feature "theater dimming," which can be set by the driver to any of several rates via the Multi-information display. The trunk has interior lighting, plus the trunk lid has lighting that illuminates the bumper and sill area when the lid is opened.


The RL interior offers plenty of storage and convenience features for driver and passengers. The front center armrest has a unique dual lid, which allows the padded armrest to be used on one side, while the lid on the other side is opened. The armrest upper portion can also be swiveled up to allow access to a large lower storage compartment. The front double beverage holder has an adjustable bottom tray that allows it to accommodate a wide range of container sizes.

Inside the glove compartment is a separate document box that allows the RL User Manual and important registration and insurance papers to be stored safely. This arrangement also frees up storage space in the main glove box compartment.

In the rear seating area, the rear folding armrest has a padded top. A pullout dual beverage holder is built into the rear armrest.


The RL has a generously sized 13.1 cubic-foot trunk that is fully finished, with all wiring concealed and the rear parcel shelf speakers and navigation unit fully protected. The acoustic properties of the trunk and the three rear deck speakers were engineered together to create the best possible sound performance out of the Acura/Bose DVD-AUDIO system. To allow room for longer items, a locking trunk pass-through is provided. A standard cargo net and a network of anchor points help keep cargo securely in position. The spare tire is located under a folding cover in the trunk floor.

For a cleaner appearance and to avoid damage to luggage, the aluminum trunk lid is supported by fully concealed hinge mechanisms. The trunk can be opened via a remote release mounted on the driver's door panel, by pulling the exterior release on the lid when carrying the Keyless Access fob, or with a manual release accessible through the locking trunk pass-through. There is also an emergency trunk opener inside, near the latch. For security, the trunk main switch is located in the glove box, which can be locked to prevent access by valets. A valet key is provided that will allow a parking attendant to operate the ignition, but will not to open the glove box, trunk, or locking trunk pass-through.


The RL has a GPS-linked, solar-sensing, dual-zone, dual-mode automatic climate control system that lets the driver and front passenger set temperature modes to their individual liking. A pair of large adjustable vents in the rear of the center console keep the rear seat area comfortable. Large, simple to use system controls are positioned within easy reach, just below the center instrument panel vents. The system can also be controlled by voice, and some seldom-needed custom settings can also be accessed through the Interface Dial. The climate control system's control logic is now designed to provide smoother operation with less pronounced and obvious changes in airflow.

With its position-sensing ability, the navigation system contributes to overall passenger comfort with 3D solar sensing. Based on its continuously updated vehicle position information, the navigation system determines the position of the sun relative to the driver and passenger. Combining this information with input from a solar sensor located on top of the instrument panel, the climate control system automatically adjusts the temperature and airflow from side to side as needed to compensate for asymmetrical solar heating.

System operation can be customized to suit the preferences of the driver and front seat passenger. Using the navigation screen and the Interface Dial, the temperature of the air flowing through the upper vents can be lowered relative to that of the air flowing from the footwell vents.


For greater passenger comfort on sunny days, the RL has a power operated rear-window sunshade, plus manually operated sunshades for each rear side window.

The 2005 RL introduces a new technology to North America, Active Noise Cancellation™ (ANC), which is designed to dramatically reduce low frequency exhaust booming noise in the interior. The system operates whenever the car is running, regardless of whether the Acura/Bose audio system is on or off.

There are two microphones in the headliner, one just behind the front overhead console, and another just ahead of the overhead rear light module. The microphones capture low-end drivetrain frequencies entering the cabin, and send a signal to the Active Noise Cancellation unit. The control unit then creates a precisely timed reverse phase audio signal that is sent to an amplifier, which powers the door speakers and the subwoofer positioned on the rear deck.

Since the system is designed to cancel low-frequency sound, it doesn't use any of the audio system's tweeters. The ANC dramatically reduces the booming sound of the exhaust, front and rear. In the frequency range below 100 hertz, ANC results in an impressive 10 dB reduction in noise level.


The overhead console incorporates a variety of useful features. Controls for the standard OnStar® service system are located here, as is the standard HomeLink® system. Other overhead console features include controls for interior lighting, power sunroof, power rear sunshade and remote retracting rear headrests.


Like the innovative and widely heralded TL audio system, the RL comes standard with a DVD-Audio entertainment system that is engineered to advance the state of the art in production car audio. The ultra-sophisticated system of the RL provides the driver and passengers with a new level of audio enjoyment utilizing the Bose® Cabin Surround® sound system.

Engineered specifically for the RL, the Acura/BOSE 10-speaker Surround Sound System with 6-disc CD, DVD-Audio and DTS changer and AM/FM tuner delivers surround sound to all seating positions and features standard XM® Satellite Radio. XM® Satellite Radio provides more than 100 channels (all 68 music channels are commercial-free) of digital program material with near-CD quality sound. A text display on the navigation screen provides information text on the program material. XM® provides virtually uninterrupted coverage of the 48 contiguous states, and a one-year subscription is included with the RL. Note that XM® Satellite Radio is not installed on RL models sold in Alaska and Hawaii-service for these states does not exist at this time.

The RL has a 6-disc in-dash changer that can play DVD-Audio, CD, MP3 and WMA media. DVD audio is the next step in audio reproduction technology. Many new releases are being issued in this new format, and many older recordings are being re-mastered and reissued to take advantage of the superior sound that DVD audio offers. With over 500 times higher resolution than CD audio, DVD audio delivers smoother, fuller and far more accurate sound. (The system will not play DVD movies, DVD-Video or DVD-R/RW.)

To improve sound quality when playing CDs, the system includes Centerpoint® logic, which creates simulated surround sound from the two channels of CD data. Another feature, Audiopilot®, automatically adjusts the audio signal in response to exterior noises. Audiopilot monitors the sound in the RL cabin using the same microphone used for the Active Noise Cancellation™ system (ANC), then the system adjusts the audio system output to compensate.

Centerpoint, Audiopilot, balance, fader and other functions can be accessed via the Interface Dial. Controls for key audio system functions are positioned within fingertip reach on the RL steering wheel. Select audio system functions can also be accomplished via voice commands.

For precise audio imaging and impressive sound for listeners in the front and rear seats, the 10 speakers are strategically located throughout the RL cabin. Each front door has a 6.5-inch full-range speaker and a separate 1.5-inch tweeter. A 2.5-inch twiddler is centered on the top of the instrument panel. Each rear door has a 6.5-inch full-range speaker; the rear parcel shelf has a 2.5-inch twiddler on each side, with a big 9-inch woofer centrally located beneath the back glass. A total of 260 watts drives the 10-speaker system.
