Luxury/Comfort/Convenience
Lexus luxury begins with how the customer first interacts with his or her vehicle. All RX models are equipped with the SmartAccess keyless entry with push-button start. As the driver approaches the vehicle, interior and exterior courtesy lamps illuminate. Opening the door, the instrument panel lighting gradually fades in. When the hybrid system is started, the instrument gauge needles and markings illuminate, followed by the multi-information display. After the driver exits the vehicle, the lights fade out at different intervals.
2011 Lexus RX 450h is equipped with a power tilt and telescopic steering column. To ease entry and exit, the seat automatically slides up to two inches rearward and the steering wheel tilts upward and slides forward when the hybrid system is switched off. Upon pushing the “ON” switch, the seat and steering wheel return to positions pre-set by the driver using the three-position memory system.
The standard 10-way power front seats are shaped to accommodate arm movement when operating the available Remote Touch, while also holding the occupants in place. Both the driver and passenger seats also feature power lumbar adjustment. Also available on the RX is a ventilation function for the front seats to help improve comfort on hot and humid days. The shape and texture of the armrests and switches offer an ideal combination of tactile feel and functionality.
The leather-wrapped three-spoke steering wheel features integrated audio controls and a unique cross-section that is designed to provide a more natural grip than a conventional round-section wheel. An optional leather and wood trimmed wheel is also available.
Three seat materials include standard fabric, optional smooth leather or even softer semi-aniline leather. In addition to light gray and black, Parchment is available as an interior color. The 2011 Lexus RX 450h also exclusively offers a black and light gray interior with striking black accents. Standard wood trim comes in Brown Walnut matched to Parchment, or Espresso Bird’s-eye Maple matched to gray and black.
The center console box provides more than 0.75 cu. ft. of storage capacity, enough space to comfortably store CDs/DVDs or the vehicle’s owner’s manual. The three-part (40/20/40) rear seats can slide fore and aft, recline, and fold down using the one-touch levers mounted in the luggage compartment. Compact rear-seat headrests help improve the driver’s visibility. The double-wishbone rear suspension, due to its compact packaging, yields a larger luggage compartment; the width between the suspension towers is increased by nearly six inches.
The quiet climate-control system offers quick cooling and warming. A high-efficiency compressor detects refrigerant flow in order to optimize engine control and fuel economy. An available smog sensor is designed to detect harmful particles (CO, HC, NOx) in other vehicles’ exhaust emissions and automatically switch between fresh air and recirculation modes. An electric compressor on the 2011 Lexus RX 450h includes a humidity sensor to help optimize air-conditioner operation, helping to enhance fuel economy.
The RX continues the tradition of offering the Lexus Premium Audio system as standard equipment, in this case a powerful nine-speaker system with a six-disc changer. Creative placement and angling of the speakers perfectly cross-channels sound to the occupant on the opposite side of the vehicle to transform the cabin into a clear, crisp acoustic environment. Bluetooth® hands free phone capability is also standard.
RX models can accommodate a variety of music sources, providing available auxiliary and USB inputs, Bluetooth Audio wireless connectivity and a standard integrated XM Radio receiver (complimentary 90-day trial subscription). When an iPod® is attached via the USB port, information such as names for the artist, track and album is displayed on the available navigation or audio screen, while the iPod can be controlled through the audio system. The large center console storage box easily accommodates a variety of electronic devices while keeping wires out of sight.
Luxury Options
An available 12-speaker system audio system comes with the optional navigation or rear seat entertainment systems and includes two-rear-door tweeters and a compact, L-shaped subwoofer in the rear-luggage compartment.
The optional 15-speaker Mark Levinson® Surround Sound system allows listeners to enjoy 7.1-channel surround sound. The Mark Levinson system, a Lexus exclusive, features a center channel coaxial speaker, metal-cone midrange speakers, tweeters and a 100-watt amplified subwoofer. A 2.5-inch speaker built into each D-pillar provides the right and left surround-sound channels. The diffusion of sound provides each occupant the same level of audio quality.
The available Hard Disc Drive (HDD) navigation system eliminates the need for DVD map discs and offers a unique voice recognition system, which can work using casual-language inputs on certain functions. An optional rear-seat entertainment system includes two high-definition seven-inch screens, one on each of the front seatbacks. Each screen can display video from separate sources. A remote control allows independent control of each screen. Rear-seat occupants can also choose to listen to audio through the wireless headphones instead of vehicle speakers.
The available wide-view side and backup cameras help provide the driver with a wider range of visibility. The driver can check hard-to-view areas by simply pressing the camera-select button on the steering wheel or, when in reverse, viewing the camera images on the navigation screen. An optional back-up camera displays images on the eight-inch navigation screen; systems without navigation have a 2.4-inch display in the rear-view mirror.
2011 Lexus RX 450h also offers a telematics system, Lexus Enform® with Safety Connect®, available by subscription. Complimentary one-year trial subscriptions are included on all purchases of new Lexus vehicles equipped with these features. Safety Connect is standard on all vehicles while Lexus Enform with Safety Connect is on all vehicles equipped with the optional Navigation system. The Lexus Enform and the Safety Connect response centers operate 24 hours a day, 7 days a week—every day of the year.
Lexus Enform vehicles are factory ready for subscriptions to a variety of innovative XM services including XM NavTraffic®, XM NavWeather™ and XM Sports and Stocks services. XM services require separate XM subscriptions. The XM Sports and Stocks service is included with an XM radio subscription. All XM services offer complimentary 90-day trial subscriptions.
Exterior Design
The Lexus RX models blend a dynamic version of L-finesse design to create a sleek profile that is accentuated by broad “shoulders” for an athletic yet elegant presence. Bright finish side-window moldings follow a subtly concaved line across the A– and C– pillars, extending at the front and rear ends.
The Lexus design cue of placing the grille lower than the headlights, along with sharper headlight graphics, yields a strong frontal expression. The 2011 Lexus RX 450h offers standard halogen and optional HID and LED headlights. The 2011 Lexus RX 450h’s unique grille features a finer pitch than on the RX 350, creating a fluid-like surface, accentuated by its silver color.
Pronounced front fenders flow into the doors, and integrated rear fender flares neatly sweep around to pull together the taut rear corners of the vehicle. The lower body emphasizes the standard 18-inch wheels. Passenger doors extend below the entry sill, helping keep out dirt and moisture.
Several exclusive design features, including the grille and front bumper, distinguish the 2011 Lexus RX 450h hybrid from the RX 350. Exclusive optional LED headlights offer a more distinctive appearance as well as longer life and lower energy consumption. Lexus hybrid blue is used for the front and rear emblems, hybrid logos, rear combination lights, and headlights.
A distinctive feature of the door handles is that the surface subtly twists outward from the front to the rear to give a comfortable grip. The side mirrors feature integrated LED turn signal lamps.
The rear spoiler’s primary function is to help lower the vehicle’s Coefficient of drag (Cd), but it also conceals the rear wiper and houses the AM/FM radio antenna and high-mount stop lamp.
Interior Design
Based on Lexus L-finesse philosophy, the dramatically designed interior clearly separates the interior into two distinct zones – the “display zone” to provide information, and the “operation zone” for interaction with controls. The shoulder of the door trim comfortably envelops the occupants, the clear line of the trim beginning inside the cabin and tapering outward toward the exterior. The design imbues a feeling of a continuous line encircling the occupants and defining the controls and displays. Neatly sculpted metallic surfaces, especially on the asymmetrical center stack, showcase a bold contrast of shadow and light.
A high contrast white Organic Light Emitting Diode (OLED) is used for the multi-information display located next to the speedometer. Vibrant white characters are sharply displayed on a high-contrast black background for ease of use and a luxurious appearance. For the 2011 Lexus RX 450h, blue accented meters strengthen the hybrid image, and a hybrid system indicator replaces the tachometer to encourage driving in an economical manner.
In addition to an Eco Driving indicator light, RX models feature an Eco driving indicator zone that displays current fuel economy using a bar graph and alerts the driver when they are achieving low fuel efficiency.
Lexus employed extensive human-machine interface (HMI) studies to enhance occupants’ interaction with all controls. To help reduce driver distraction and effort, each HMI function in the RX wastes no movement. The available eight-inch navigation display (or seven-inch audio/HVAC display when navigation is not ordered) is placed at a higher, more distant position, providing a more natural visual angle.
Three innovations to come from the HMI studies include the multi-information switch on the steering wheel, the Remote Touch console-mounted navigation controller and the available Heads-Up Display. The multi-information switch allows the driver to access numerous function settings without taking hands off the steering wheel, and reduces the number of individual switches, contributing to a cleaner instrument panel. Vehicle settings can be customized according to personal preference, including personal door-lock preferences, interior/exterior light adjustments, driver’s seat easy exit, and window-closure settings.
The available navigation system can be controlled using either the Remote Touch device or by utilizing voice command. Remote Touch allows the user to operate the navigation system, climate, audio, phone controls and more. The screen menus are selected with the controller, eliminating the need to reach out and reducing eye movement.
The attribute that most distinguishes Lexus’ navigation controller from other devices in other luxury models is its “haptic”-feedback technology, which provides a tactile response to the hand. As the user operates the controller near a screen icon, the cursor is pulled to that icon with feedback from a servomotor in the device enabling the user to feel it “click” into place. The driver or passenger makes a selection by pressing the side enter button on either side, and the feedback servo is adjustable for sensitivity. The system then confirms the action with a subtle sound. Remote Touch integrates the functions of seven hard switches used with the previous touch screen, helping users to operate those functions with reduced effort and distraction.
The available Heads-Up Display (HUD) utilizes white readouts. High-intensity LEDs project high-contrast white figures onto the windshield, which are easier to read – and easier on the eyes – than the typical green-colored readouts. The HUD offers displays for speed, navigation, and audio. A wedge-shaped windshield interlayer for the HUD projection area eliminates the distracting printed grid pattern seen on some other vehicles equipped with HUDs.
Warranty
All new Lexus vehicles come with a 48-month/50,000-mile basic limited warranty with roadside assistance for 48-months/unlimited miles. Powertrain and restraint system coverage is provided for 72 months/70,000 miles. Corrosion perforation protection is covered for 72 months, regardless of mileage. The hybrid-related components, including the HV battery, battery-control module, hybrid control module and inverter with converter, are covered for eight years/100,000 miles.
