SDM (Stabilizer with Disconnection Mechanism)^{* *}If equipped SDM (Stabilizer with Disconnection Mechanism) is a system that switches conditions of the front stabilizer to maintain vehicle stability and drivability on paved road and off-road situations. How SDM (Stabilizer with Disconnection Mechanism) works Depending on the switch operation or vehicle speed, the stabilizer is locked/unlocked, which results in the following effects. During driving on paved roads The stabilizer is locked and the movement of the suspensions is restrained, resulting in stable driving. During off-road driving The stabilizer is unlocked and it becomes easier that the suspensions extend and retract, leading to improvement of drivability on rough roads The vibration of the vehicle body is reduced, which helps enhance riding comfort. Turning the system on/off Press the SDM switch The stabilizer is unlocked and the SDM indicator will come on. Press the switch again to lock the stabilizer (the SDM indicator will turn off). While the stabilizer is being locked or unlocked, the SDM indicator flashes. Note: Operation conditions by the switch The engine switch is in ON and the vehicle speed is approximately 18 mph (30 km/h) or less. Automatic control by vehicle speed The stabilizer will be locked again when the vehicle speed exceeds approximately 18 mph (30 km/h). Operation sounds When the stabilizer is being locked or unlocked, an operating sound may be heard from the underside of the vehicle. However, it does not indicate a malfunction. When the state of the SDM indicator differs from the stabilizer status On an uneven surface, the stabilizer status may not be switched and may differ from the state of the SDM indicator. The stabilizer status will be switched after the vehicle is driven and the suspensions extend or retract. When the outside temperature is extremely low Do not use the system when the outside temperature is below -22°F (-30°C), as the system may not operate properly. After the engine switch is turned to OFF The stabilizer status is hold even when the engine switch is turned to OFF. To switch the status, turn the engine switch to ON again and press the SDM switch. When the stabilizer is unlocked When the stabilizer is unlocked, some of the Toyota Safety Sense 3.0 are not operate. (When using the SDM (Stabilizer with Disconnection Mechanism) (if equipped))
