Starting and operating/Driver’s Control Center Differential (C.DIFF/DCCD) (STI)

– When a temporary spare tire
is installed
– When your vehicle is towed
– When the vehicle is stopped
with the manual mode selected

NOTE

Pull the switch rearward to reduce the
initial LSD torque. When the lowest position of the driver’s control center differential indicator is displayed, 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:

. 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, 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. 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 between 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 sometimes 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 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 on the combination meter
continues to show the driver’s selected
initial LSD torque. When the driver releases the parking brake lever, the initial
LSD torque set by the driver is restored.
