7-22 Starting and operating . When a temporary spare tire is installed . When your vehicle is towed . When the vehicle is stopped with the manual mode selected NOTE . A higher initial LSD torque setting gives the vehicle greater traction when driving straight ahead but makes cornering more difficult. Remember this when adjusting the initial LSD torque. In general, higher initial LSD torque settings assist driving on slippery roads and lower settings for non-slippery roads. When the vehicle is stuck in snow or mud, pushing the center differential control switch forward more than once until the "LOCK" indicator is illuminated will help to free the vehicle. . The setting of the initial LSD torque will remain even when the auto mode is selected or the ignition switch is turned to the "OFF" position. However, the initial LSD torque will be minimized when the battery is disconnected and reconnected. . During cornering or when making turns (especially when going into the garage), the rotational difference be- Pull the switch rearward to reduce the initial LSD torque. When the lowest position of the driver's control center differential indicator light illuminates, the initial LSD torque will be minimum. Under this condition, only the Mechanical LSD torque will limit the differential action. CAUTION . Do not operate the control switch when a wheel slippage occurs. Wait until the wheelspin has been brought under control. . Under any of the following conditions after setting to the manual mode, pull the center differential control switch to minimize the initial LSD torque: tween the front and rear wheels may cause a braking effect accompanied by vibration and noise. This does not indicate a problem. The phenomenon will disappear when you pull the center differential control switch rearward more than once until the initial LSD torque becomes the minimum. In the auto mode, it controls the initial LSD torque automatically. While in the auto mode, this phenomenon sometimes occurs depending on the driving condition, however, it does not indicate a problem. . Use the center differential indicator light only as a rough indication of the initial LSD torque. . If you operate the center differential control switch while quickly accelerating or turning a tight corner, you may feel slight shocks. This is due to differential action by the center differential and does not indicate a problem. & Temporary release When the driver stops the vehicle and pulls the parking brake lever after manually setting the initial LSD torque, the LSD torque is temporarily minimized. However the indicator in the combination meter continues to show the driver's selected initial LSD torque. When the driver re-
