Nissan Sentra B18 (2020-2025) Owner's Manual: Vehicle Dynamic Control (VDC) system

The Vehicle Dynamic Control (VDC) system on the Nissan Sentra uses multiple advanced sensors to continuously monitor driver inputs, wheel speed, steering angle, and overall vehicle motion in real time.

Under certain driving conditions, the Nissan Sentra VDC system actively supports vehicle stability and traction by performing the following functions:

• Controls brake pressure to reduce wheel slip on a slipping drive wheel, allowing power to be transferred efficiently to a non-slipping drive wheel on the same axle, improving traction.
• Controls both brake pressure and engine output to limit drive wheel slip based on vehicle speed, providing an integrated traction control function for the Nissan Sentra.
• Individually controls brake pressure at each wheel and adjusts engine output to help the driver maintain vehicle control in the following situations:
  • Understeer, where the vehicle tends to continue straight instead of following the intended steering path despite increased steering input.
  • Oversteer, where the vehicle may begin to rotate or spin due to specific road surfaces or driving conditions.

The VDC system in the Nissan Sentra is designed to assist the driver in maintaining control of the vehicle; however, it cannot prevent loss of control in every driving situation, especially in extreme conditions.

When the VDC system is actively operating, the indicator light in the instrument panel flashes to indicate the following:

• The road surface may be slippery, or the system has determined that corrective action is necessary to help keep the Nissan Sentra on the intended path.
• You may feel a pulsation in the brake pedal and hear noise or vibration from under the hood. This is normal and confirms that the VDC system is functioning correctly.
• The driver should reduce speed and adjust driving behavior according to current road and weather conditions.

If a malfunction occurs within the system, the indicator light illuminates in the instrument panel. When this indicator is on, certain VDC functions are disabled.

The vehicle information display can be used to manually turn off the VDC system. When this is done, the indicator light and the AEB system warning light illuminate, confirming that the VDC system has been switched off.

Even when the VDC system is turned off via the vehicle information display, the Nissan Sentra will continue to prevent a single drive wheel from slipping by transferring power to a non-slipping wheel. In this case, the indicator light flashes. All other VDC functions remain inactive, and the indicator light will not flash.

The VDC system automatically resets to ON each time the ignition switch is turned from the OFF position back to the ON position.

The onboard computer includes a self-diagnostic feature that checks the VDC system whenever the engine is started and the Nissan Sentra begins moving forward or in reverse at low speed. During this self-test, a brief clunk sound or brake pedal pulsation may be felt. This behavior is normal and does not indicate a malfunction.

WARNING

• The VDC system is designed to enhance vehicle stability but does not prevent accidents caused by abrupt steering inputs at high speeds or careless driving. Always reduce speed and use extra caution when cornering or driving on slippery surfaces.
• Do not modify the vehicle’s suspension.

  If suspension components such as shock absorbers, struts, springs, stabilizer bars, bushings, or wheels are not NISSAN-recommended or are severely worn, the VDC system may not function correctly. This may negatively affect handling performance, and the indicator light may flash or the indicator light may illuminate.

• If brake-related components such as pads, rotors, or calipers are not NISSAN-recommended or are excessively worn, the VDC system may not operate properly and the indicator light may illuminate.
• If engine control components are not NISSAN-recommended or are significantly deteriorated, the indicator light may illuminate.
• When driving on extremely inclined surfaces, such as sharply banked corners, the VDC system may not operate properly and the indicator light may flash or the indicator light may illuminate. Avoid driving on these surfaces.
• When driving on unstable surfaces such as a turntable, ferry, elevator, or ramp, the indicator light may flash or the indicator light may illuminate. This condition does not indicate a malfunction.

After driving onto a stable and level surface, restart the engine to allow the Nissan Sentra Vehicle Dynamic Control (VDC) system to recalibrate and resume normal operation.

If wheels or tires other than those recommended by NISSAN for the Nissan Sentra are installed, the VDC system may not function correctly and the indicator light may flash or the indicator light may illuminate, indicating reduced system performance.

Rise-up and build-up

The VDC system gradually and smoothly adjusts braking force during normal braking events. This controlled increase in brake pressure helps deliver a refined and predictable brake feel for the Nissan Sentra driver, improving comfort and confidence.

Brake force distribution

When braking while cornering, the system intelligently optimizes brake force distribution between the front and rear wheels. This adjustment is based on the turning radius and vehicle dynamics, helping the Nissan Sentra maintain balanced stability through curves.

WARNING

• The VDC system is designed to assist the driver in maintaining vehicle stability; however, it cannot prevent accidents caused by sudden steering at high speeds or unsafe driving behavior. Always reduce speed and exercise extra caution when driving or cornering on slippery surfaces.
• Do not modify the vehicle's suspension.

  If suspension components such as shock absorbers, struts, springs, stabilizer bars, bushings, or wheels are not NISSAN-recommended for the Nissan Sentra or are excessively worn, the VDC system may not operate properly. This can negatively affect handling performance, and the indicator light may flash or the indicator light may illuminate.

• If brake-related components such as brake pads, rotors, or calipers are not NISSAN-recommended or are severely worn, the VDC system may not operate as intended and the indicator light may illuminate.
• If engine control components are not NISSAN-recommended or are significantly deteriorated, the indicator light may illuminate.
• When driving on extremely inclined surfaces, such as highly banked corners, the VDC system may not operate correctly and the indicator light may flash or the indicator light may illuminate. Avoid driving on these types of roads.
• When driving on unstable surfaces such as a turntable, ferry, elevator, or ramp, the indicator light may flash or the indicator light may illuminate. This condition does not indicate a malfunction.

  Once the vehicle is back on a stable surface, restart the engine to restore normal VDC system operation.

• If wheels or tires other than NISSAN-recommended specifications are used, the VDC system may not function properly and the indicator light may flash or the indicator light may illuminate.
• The Nissan Sentra VDC system does not replace the need for winter tires or tire chains when driving on snow-covered roads.

After driving the Nissan Sentra onto a stable and level surface, restart the engine to allow the Vehicle Dynamic Control (VDC) system to reset and return to normal operation.

If wheels or tires other than those recommended by NISSAN for the Nissan Sentra are installed, the VDC system may not operate correctly and the indicator light may flash or the indicator light may illuminate, indicating reduced or altered system functionality.

Rise-up and build-up

During normal braking, the Nissan Sentra VDC system gradually increases braking force to provide smoother and more consistent brake response, contributing to enhanced pedal feel and improved driver confidence.

Brake force distribution

When braking while cornering, the system intelligently optimizes brake force distribution between the front and rear wheels based on the turning radius. This helps the Nissan Sentra maintain balanced stability and predictable handling through curves.
