4 WHEEL ACTIVE STEER (4WAS) SYSTEM (if so equipped) WARNING ● The VDC system is designed to help improve driving stability but does not prevent accidents due to abrupt steering operation at high speeds or due to careless or dangerous driving techniques. Reduce vehicle speed and be especially careful when driving and cornering on slippery surfaces and always drive carefully. ● If engine related parts such as muffler are not standard equipment or are extremely deteriorated, the "VDC OFF" indicator or "SLIP" indicator or both indicator lights may illuminate. ● Do not modify the vehicle's suspension. If suspension parts such as shock absorbers, struts, springs, stabilizer bars and bushings are not INFINITI approved or are extremely deteriorated the VDC system may not operate properly. This could adversely affect vehicle handling performance, and the "VDC OFF" indicator or "SLIP" indicator or both indicator lights may illuminate. ● If brake related parts such as brake pads, rotors and calipers are not standard equipment or are extremely deteriorated, the "VDC OFF" indicator or "SLIP" indicator or both indicator lights may illuminate. ● When driving on extremely inclined surfaces such as higher banked corners, the VDC system may not operate properly and the "VDC OFF" indicator or "SLIP" indicator or both indicator lights may illuminate. Do not drive on these types of roads. ● When driving on unstable surfaces such as a turntable, ferry, elevator or ramp, the "VDC OFF" indicator or "SLIP" indicator or both indicator lights may illuminate. This is not a malfunction. Restart the engine after driving onto a stable surface. ● If wheels or tires other than those recommended are used, the VDC system may not operate properly and "VDC OFF" indicator or "SLIP" indicator or both indicator lights may illuminate. ● The VDC system is not a substitute for winter tires or tire chains on a snow covered road. The 4 Wheel Active Steer (4WAS) system is an electronically controlled four-wheel steering system. Depending on the vehicle speed and steering angle, the angles of the front and rear wheels are adjusted by the 4WAS system to help improve driving performance. If a malfunction occurs in the system, the 4WAS function will stop but the ordinary two-wheel steering system will operate normally. The "4WAS" warning light will illuminate. If the light illuminates while you are driving, contact an INFINITI dealer for repair. The steering wheel may be slightly turned even when driving on a straight road due to a protection mechanism for the 4WAS system. This is not a malfunction. The steering wheel will return to the normal position after the protection mechanism deactivates. The protection mechanism activates under the following conditions: ● The steering wheel is operated forcibly when it is hard to operate or the tires are blocked by obstacles. ● The steering wheel is continuously operated when the vehicle is parked or being driven at extremely low speed. 5-50 Starting and driving
