Vehicle dynamic control (VDC) system
Starting and driving 5-177
When the vehicle information display is used to turn off the system, the VDC sys- tem still operates to prevent one drive wheel from slipping by transferring power to a non-slipping drive wheel. The indicator light flashes if this occurs. All other VDC functions are off and the indicator light will not flash. The VDC system is automatically reset to on when the ignition switch is placed in the OFF position then back to the ON position. The computer has a built-in diagnostic fea- ture that tests the system each time you start the engine and move the vehicle for- ward or in reverse at a slow speed. When the self-test occurs, you may hear a clunk noise and/or feel a pulsation in the brake pedal. This is normal and is not an indica- tion of a malfunction.
WARNING
• The VDC system is designed to help
the driver maintain stability but does not prevent accidents due to abrupt steering operation at high speeds or by careless or dangerous driving techniques. Reduce vehicle speed and be especially careful when driv- ing and cornering on slippery sur- faces and always drive carefully.
• Do not modify the vehicle's suspen- sion. If suspension parts such as shock absorbers, struts, springs, sta- bilizer bars, bushings and wheels are not NISSAN recommended for your vehicle or are extremely deterio- rated, the VDC system may not oper- ate properly. This could adversely af- fect vehicle handling performance, and the indicator light may flash or both the and indicator lights may illuminate.
• If brake related parts such as brake pads, rotors and calipers are not NISSAN recommended or are ex- tremely deteriorated, the VDC sys- tem may not operate properly and both the and the indicator lights may illuminate.
• If engine control related parts are not NISSAN recommended or are ex- tremely deteriorated, both the and indicator lights may illuminate.
• When driving on extremely inclined surfaces such as higher banked cor- ners, the VDC system may not oper- ate properly and the indicator light may flash or both the and
indicator lights may illuminate. Do not drive on these types of roads.
• When driving on an unstable surface such as a turntable, ferry, elevator or ramp, the indicator light may flash or both the and indi- cator lights may illuminate. This is not a malfunction. Restart the engine after driving onto a stable surface.
• If wheels or tires other than the NISSAN recommended ones are used, the VDC system may not oper- ate properly and the indicator light may flash or both the and
indicator lights may illuminate.
• The VDC system is not a substitute
for winter tires or tire chains on a snow covered road.
5-178 Starting and driving
HOW TO TURN OFF THE VDC SYSTEM The vehicle should be driven with the Ve- hicle Dynamic Control (VDC) system ON for most driving conditions. When the vehicle is stuck in mud or snow, the VDC system reduces the engine output to reduce wheel spin. The engine speed will be reduced even if the accelerator is de- pressed to the floor. If maximum engine power is needed to free a stuck vehicle, turn the VDC system off.
To turn off the VDC system, perform the following steps in the vehicle information display. 1. Press the button on the steering
wheel until “Settings” appears and then press the OK button.
2. Use the scroll dial to select the “VDC Set- ting” and then press the OK button.
3. Select “System” and press the OK button. The indicator light will illuminate.
Turn “VDC Setting” back on in the vehicle information display or restart the engine to turn on the VDC system.
RISE-UP AND BUILD-UP The system gradually adjusts braking power during normal braking to help pro- vide an enhanced brake feel. BRAKE FORCE DISTRIBUTION During braking while driving through turns, the system optimizes the distribution of force to each of the four wheels depending on the radius of the turn.
WARNING
• The VDC system is designed to help
the driver maintain stability but does not prevent accidents due to abrupt steering operation at high speeds or by careless or dangerous driving techniques. Reduce vehicle speed and be especially careful when driv- ing and cornering on slippery sur- faces and always drive carefully.

The chassis control is an electric control module that includes the following functions: • Intelligent Trace Control • Active Ride Control (if so equipped) INTELLIGENT TRACE CONTROL (I-TC) This system senses driving based on the driver’s steering and acceleration/braking patterns, and controls brake pressure at individual wheels to aid tracing at corners and help smooth vehicle response. When the VDC system is turned off, the I-TC is also turned off. The amount of brake control is changed based on Drive Mode Selector. When the I-TC is not functioning properly, the master warning light illuminates, and the warning message “Chassis Control System Error” will also appear in the vehicle information display. If the chassis control warning message ap- pears in the vehicle information display, it may indicate that the I-TC is not function- ing properly. Have the system checked as soon as possible. It is recommended that you visit a NISSAN dealer for this service. For
