Technical terms RON (Research Octane Number) The Research Octane Number for gasoline as determined by a standardized method. It is an indication of a gasoline's ability to resist undesired detonation (knocking). The average of both the ->MON (Motor Octane Number) and RON (Research Octane Number) is posted at the pump, also known as ANTI-KNOCK INDEX. Shift lock When the vehicle is parked, this lock prevents the transmission selector lever from being moved out of position P without key turned and brake pedal depressed. SRS (Supplemental Restraint System) Seat belts, emergency tensioning device and airbags. Though independent systems, they are closely interfaced to provide effective occupant protection. Tele Aid System* (Telematic Alarm Identification on Demand) The Tele Aid system consists of three types of response: automatic and manual emergency, roadside assistance and information. Tele Aid is initially activated by completing a subscriber agreement and placing an acquaintance call. The Tele Aid system is operational providing that the vehicle's battery is charged, properly connected, not damaged and cellular and GPS coverage is available. Telematics* A combination of the terms "telecommunications" and "informatics". Tightening torque Force times lever arm (e.g. a lug wrench) with which threaded fasteners such as wheel bolts are tightened. Tire speed rating Part of tire designation; indicates the speed range for which a tire is approved. Traction Force exerted by the vehicle on the road via the tires. Transfer case Speed of rotation/torque converter that works together with the ->automatic transmission. In the LOW mode off-road position, the transfer case decreases the output rotational speed of the ->automatic transmission by approximately half. This results in a corresponding increase of torque on the drive axles. The vehicle then has nearly double the driving force but drives only approximately half as fast. 296
