on both sides of the vehicle, the system “looks” for other vehicles in the blind zone areas of the Impala and indicates their presence with LED-lit symbols in the outside mirrors. Rear cross-traffic alert features. Honda 2003: Honda introduced an autonomous braking (Collision Mitigation Brake System CMBS, originally CMS) front collision avoidance system on the Inspire and later in Acura, using a radar-based system to monitor the situation ahead and provide brake assistance if the driver reacts with insufficient force on the brake pedal after a warning in the instrument cluster and a tightening of the seat belts. The Honda system was the first production system to provide automatic braking. The 2003 Honda system also incorporated an "E-Pretensioner", which worked in conjunction with the CMBS system with electric motors on the seat belts. When activated, the CMBS has three warning stages. The first warning stage includes audible and visual warnings to brake. If ignored, the second stage would include the E-Pretensioner's tugging on the shoulder portion of the seat belt two to three times as an additional tactile warning to the driver to take action. The third stage, in which the CMBS predicts that a collision is unavoidable, includes full seat belt slack takeup by the E-Pretensioner for more effective seat belt protection and automatic application of the brakes to lessen the severity of the predicted crash. The E-Pretensioner would also work to reduce seat belt slack whenever the brakes are applied and the brake assist system is activated. Jaguar Land Rover As part of the InControl suite of services, Jaguar Land Rover provides several driver assistance technologies, amongst which are autonomous emergency braking, intelligent emergency braking, lane departure warning, blind spot monitor and blind spot assist. The systems variously use both microwave and optical detection methods. Mercedes-Benz 2002: Mercedes' "Pre-Safe" system was exhibited at the Paris Motor Show on the 2003 S-Class. Using electronic stability control sensors to measure steering angle, vehicle yaw, and lateral acceleration and brake assist (BAS) sensors to detect emergency braking, the system can tighten the seat belts, adjust seat positions, including rear seats (if installed), raise folded rear headrests (if installed), and close the sunroof if it detects a possible collision (including rollover). A later version of the Pre-Safe system was supplemented by an additional function that can close any open windows if necessary. 2006: Mercedes-Benz's "Brake Assist BAS Plus" was their first forward
