PRECAUTIONS
• If the following components are replaced with non-genuine components or converted, VDC OFF indicator
lamp and SLIP indicator lamp may turn on or the VDC system may not operate properly. Components
related to suspension (shock absorber, strut, spring, bushing, etc.), Tires, wheels (exclude specified size),
components related to brake (pad, rotor, caliper, etc.), components related to engine (muffler, ECM, etc.),
components related to body reinforcement (roll bar, tower bar, etc.).
• Driving in the condition of breakage or excessive wear of suspension, tires or components related to the
brakes may cause VDC OFF indicator lamp and SLIP indicator lamp turn on, and the VDC system may not
operate properly.
• When the TCS or VDC is activated by sudden acceleration or sudden turn, some noise may occur. The
noise is a result of the normal operation of the TCS and VDC.
• When driving on roads which have extreme slopes (such as mountainous roads) or high banks (such as
sharp carves on a freeway), the VDC may not operate normally, or VDC OFF indicator lamp and SLIP indi-
cator lamp may turn on. However, this is not a malfunction, if normal operation can be resumed after restart-
ing engine.
• Sudden turns (such as spin turns, acceleration turns), drifting, etc. When VDC function is OFF (VDC OFF
SW ON) may cause the G sensor system indicate a malfunction. However, this is not a malfunction, if nor-
mal operation can be resumed after restarting engine.
• Change 4 tires at a time. Be sure to use specified-size tires that have the same brand name and pattern.
Wheel sensor errors can be detected be self-diagnosis when tires have wide abrasion variations or the size
is different from the genuine tires.

To adjust neutral position of steering angle sensor, make sure to use CONSULT-III.
(Adjustment can not be done without CONSULT-III.)
1.
Stop vehicle with front wheels in straight-ahead position.
2.
Touch “WORK SUPPORT” and “ST ANGLE SENSOR ADJUSTMENT” on CONSULT-III screen in this
order.
3.
Touch “START”.
CAUTION:
Do not touch steering wheel while adjusting steering angle sensor.
4.
After approximately 10 seconds, touch “END”. (After approximately 60 seconds, it ends automatically.)
