Technical terms Restraint systems Seat belts, child restraints, lower anchors and tethers for children (LATCH). As independent systems, their protective functions complement one another. Rim ( page 356) Roll bars Occupant protection system which consists of tubular steel, integrated in the rear head restraints. The roll bars are lowered into the car body during normal driving conditions and raised automatically in an accident or in a critical driving situation. 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. RFI* (Run Flat Indicator) The Run Flat Indicator monitors the set tire inflation pressures by evaluating each wheel's rotational speed. If a wheel's rotational speed changes due to falling tire inflation pressure, a corresponding warning message appears in the multifunction display. Shift lock When the vehicle is parked, this lock prevents the gear selector lever from being inadvertently moved out of position P without SmartKey turned and brake pedal depressed. Sidewall ( page 356) Soft top Soft top roof that can be opened by pulling and closed by pressing a switch and stored in the soft top compartment in the trunk area. SRS (Supplemental Restraint System) Air bags, air bag control unit (with crash sensor), emergency tensioning device. Though independent systems, they are closely interfaced to provide effective occupant protection. Steering wheel gearshift control (CLK 500*, CLK 55 AMG) You can change the gears yourself with the steering wheel gearshift buttons. 491
