Active Torque Transfer System Type SH only Your Honda is equipped with an Active Torque Transfer System (ATTS). Under certain driving conditions, the ATTS enhances the vehicle's cornering performance by transferring some torque between the inside and outside front wheels during a turn. Based on steering wheel turn angle, lateral acceleration, and engine power, the ATTS regulates the driving force to each drive wheel through an electronically-controlled hydraulic system and two sets of clutches and gears. Important Safety Information The ATTS cannot prevent skidding if you enter a corner too fast. It has almost no effect on braking and vehicle speed. It is still your responsibility to drive at reasonable speeds and to leave a sufficient margin of safety. ATTS Indicator ATTS INDICATOR The Active Torque Transfer System (ATTS) is self-checking. If a problem is detected in the system, the ATTS indicator on the instrument panel comes on. If this happens, take the vehicle to your dealer to have it checked. With the indicator on, your vehicle will corner normally, but you will not have active torque transfer. Driving
