7-22 Starting and operating/Driver’s Control Center Differential (C.DIFF/DCCD) (STI) – When your vehicle is towed – When the vehicle is stopped with the manual mode se- lected NOTE Pull the switch rearward to reduce the initial LSD torque. When the lowest posi- tion of the driver’s control center differen- tial indicator is displayed, the initial LSD torque will be minimum. 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 con- ditions after setting to the man- ual mode, pull the center differ- ential control switch to minimize the initial LSD torque: – When a temporary spare tire is installed . A higher initial LSD torque setting gives the vehicle greater traction when driving straight ahead but makes cor- nering 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-slip- pery roads. When the vehicle is stuck in snow or mud, setting the initial LSD torque to the maximum 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 “LOCK”/“OFF” position. How- ever, the initial LSD torque will be minimized when the battery is discon- nected and reconnected. . During cornering or when making turns (especially when going into the garage), the rotational difference be- 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 setting the initial LSD torque to the minimum. In the auto mode, it controls the initial LSD torque automatically. While in the auto mode, this phenomenon some- times occurs depending on the driving condition, however, it does not indicate a problem. . Use the center differential indicator only as a rough indication of the initial LSD torque. . If you operate the center differential control switch while quickly accelerat- ing or turning a tight corner, you may feel slight shocks. This is due to differential action by the center differ- ential and does not indicate a problem. & Temporary release When the driver stops the vehicle and pulls the parking brake lever after manu- ally setting the initial LSD torque, the LSD torque is temporarily minimized. However the indicator on the combination meter continues to show the driver’s selected initial LSD torque. When the driver re- leases the parking brake lever, the initial LSD torque set by the driver is restored.
