Toyota Sienna Dynamic Laser Cruise Control 2004 Minivan Specification

The 2004 Toyota Sienna Minivan equipped with Dynamic Laser Cruise Control (DLCC) represents an early adoption of advanced driver assistance systems in the minivan segment. DLCC uses a forward-facing laser sensor to monitor the distance between the Sienna and the vehicle ahead, automatically adjusting the speed to maintain a preset following distance. This system enhances safety and convenience, particularly on highways and in stop-and-go traffic conditions.

The sensor, integrated into the front grille, continually scans the road, allowing the vehicle to decelerate or accelerate as necessary without driver intervention. DLCC is activated and controlled via steering wheel-mounted buttons, enabling drivers to set their desired speed and following distance. The system operates at speeds above approximately 25 mph and disengages when the brakes are applied, requiring manual reactivation.

Under the hood, the 2004 Toyota Sienna features a 3.3-liter V6 engine, producing 230 horsepower and 242 lb-ft of torque, paired with a 5-speed automatic transmission. This powertrain ensures smooth and responsive performance, complementing the capabilities of the DLCC system. The minivan's design incorporates a unibody structure, providing a balance of rigidity and comfort, while the suspension system includes independent MacPherson struts at the front and a torsion beam at the rear, contributing to a stable and controlled ride.

The interior of the Sienna offers ample space, seating for up to eight passengers, and flexible seating configurations to accommodate varying passenger and cargo needs. The cabin is equipped with user-friendly controls and a range of comfort features. Safety is further bolstered by standard features such as anti-lock brakes, traction control, and multiple airbags.

Overall, the 2004 Toyota Sienna with Dynamic Laser Cruise Control showcases a blend of innovation and practicality, setting a benchmark for family-oriented vehicles in its class.
