![]() Like its predecessor, the RX 330 uses a center differential to split engine power evenly between the front and rear wheels. ![]() In addition, driveshaft elements are situated in a straighter line, which helps reduce friction and driveline noise. The new four-wheel drive system for the RX 330 is simpler and lighter than the one used previously and uses VSC to redirect engine power when wheel slippage occurs. In both models, VSC helps keep the vehicle going on its intended course by detecting front wheel slide and rear-wheel slide during cornering and attempting to control either condition with torque intervention and/or by braking individual wheels. All RX 330 models with the air suspension system are equipped with a multi-mode automatic (sequential) transmission.īoth the front-drive and four-wheel drive RX 330 models come equipped with the Vehicle Stability Control (VSC) system as standard. The low-pressure tank ensures quick suspension lowering response time. A central electronic control unit (ECU) controls the valves in response to signals from the height sensors. There is a height-control valve between the compressor and each of the pneumatic cylinders, and a height sensor for each axle. Each of the cylinders integrates an air spring and shock absorber. The driver can select this mode while the vehicle is idling in the Park position, and the RX 330 can change to "Access" mode automatically when the ignition switch is turned off if the driver chooses.Ĭomponents of the air suspension system include a compressor/dryer unit mounted at the rear of the vehicle, a low-pressure tank under the floor and a pneumatic cylinder at each wheel. The air suspension's "Access" mode lowers ride height by 1.2 inches (30 mm) to make it easier to exit or load/unload the RX 330. ![]() For driving over rough roads or unpaved trails at speeds of 30 mph or under, the driver can select the "High" position, which increases ground clearance by 1.2 inches (30 mm) and also increases the angles of approach and departure. The air suspension system helps boost the light-duty off-road capability that some customers want without compromising the on-road performance and comfort that are cornerstones of the vehicle's appeal and success. ![]() A driver-selectable "Low" mode reduces ride height by 0.6 inches (15 mm), resulting in more responsive steering and better tracking through curves and further supports the vehicle's sedan-like driving characteristics. The vehicle returns to normal ride height when speed falls below about 50 mph (80 km/h). In "Normal" mode, the system lowers ride height by 0.3 inches (7 mm) when vehicle speed exceeds 62 mph (100 km/h) to reduce aerodynamic drag for better handling and ride comfort. Four driver-selectable height settings allow the driver to tailor the RX 330 to specific driving conditions or needs. Automatic leveling ensures generous suspension travel and helps to preserve ride comfort. It uses lasers to measure distance from a vehicle traveling ahead and maintain a set distance from it.Ī new optional air suspension system helps enhance handling, driving comfort, and versatility in the RX 330. In place of the standard cruise control system, customers can choose Adaptive Cruise Control (ACC) like that offered on the Lexus LS 430 flagship sedan. As a result, the driver can see further into a curve. A central controller calculates the optimum lighting direction based on input from vehicle speed and steering angle and swivels the right and left headlights independently. Rain-sensing windshield wipers and High-Intensity Discharge (HID) headlights are expected in this segment, but Lexus goes further by offering an Adaptive Front lighting System (AFS) for better illumination in turns and curves. The new RX 330 offers several options designed to help improve visibility for night driving and poor weather conditions. "Lexus customers expect any new technology to improve the driving experience, not to complicate or frustrate it," said Denny Clements Lexus group vice president and general manager.Īdaptive Headlight And Cruise Control Systems New technology added to the RX 330 was designed to make the vehicle easier and more enjoyable to drive and more comfortable for passengers. In addition, Lexus increased standard luxury content in the new RX 330 compared to the previous model while making new premium-level options available. The all-new 2004 Lexus RX 330 is equipped with driveline and safety systems that provide the RX driver and passengers with even greater peace of mind in all types of driving conditions. The vehicle that started it all is back with more luxury features than ever.
