Driving Recommended shift speeds Upshift according to the following chart: Upshifts when accelerating (recommended for best fuel economy) Shift from: 1-2 15 mph (24 km/h) 2-3 25 mph (40 km/h) 3-4 40 mph (64 km/h) 4-5 45 mph (72 km/h) 5-6 50 mph (80 km/h) The instrument cluster will show the current selected gear you are in. In order to prevent the engine from running at too low an RPM, which may cause it to stall, the SST will automatically make some downshifts even if it has determined that you have not downshifted in time. Although the SST will make some downshifts for you, it will still allow you to downshift at any time as long as the SST determines that the engine will not be damaged from over-revving. Engine damage may occur if excessive engine revving is held without shifting. REVERSE SENSING SYSTEM (IF EQUIPPED) The reverse sensing system (RSS) sounds a tone to warn the driver of obstacles near the rear bumper when R (Reverse) is selected and the vehicle is moving at speeds less than 3 mph (5 km/h). The system is not effective at speeds above 3 mph (5 km/h) and may not detect certain angular or moving objects. WARNING: To help avoid personal injury, please read and understand the limitations of the reverse sensing system as contained in this section. Reverse sensing is only an aid for some (generally large and fixed) objects when moving in reverse on a flat surface at "parking speeds". Inclement weather may also affect the function of the RSS; this may include reduced performance or a false activation. 259 2011 Taurus Owners Guide, 3rd Printing USA (fus)
