VDC FunctionNFS0003Y

In addition to the TCS/ABS function, the driver steering amount and brake operation amount are detected
from the steering angle sensor and pressure sensor, and the vehicle's driving status (amount of under-
steering / over-steering) is determined from information from the yaw rate/side G sensor, wheel sensor,
etc., and this information is used to improve vehicle stability by controlling the braking and engine power
to all four wheels.

The SLIP indicator lamp flashes to inform the driver of VDC operation.

During VDC operation, the body and brake pedal lightly vibrate and mechanical noises may be heard.
This is normal.

The ABS warning lamp, VDC OFF indicator lamp, and SLIP indicator lamp might turn on when the vehicle
is subject to strong shaking or large vibration, such as when the vehicle is on a turn table or a ship while
the engine is running. In this case, restart the engine on a normal road, and if the ABS warning lamp, VDC
OFF indicator lamp, and SLIP indicator lamp turn off, there is no problem.
TCS FunctionNFS0003Z

The wheel spin of the drive wheels is detected by the VDC/TCS/ABS control unit from the wheel speed
signals from the four wheels, so if wheel spin occurs, the rear wheel right and left brake fluid pressure
control and engine fuel cut are conducted while the throttle value is restricted to reduce the engine torque
and decrease the amount of wheel spin. In addition, the degree the throttle is opened is controlled to
achieve the optimum engine torque.

Depending on road circumstances, the driver may have a sluggish feel. This is normal, because the opti-
mum traction has the highest priority under TCS operation.

TCS may be activated any time the vehicle suddenly accelerates, suddenly downshifts, or is driven on a
road with a varying surface friction coefficient.

During TCS operation, it informs a driver of system operation by flashing SLIP indicator lamp.
