Subaru Forester: Vehicle Dynamics Control system / System features

In the event of wheelspin and/or skidding on a slippery road surface and/or during cornering and/or an evasive maneuver, the Vehicle Dynamics Control system adjusts the engine’s output and the wheels’ respective braking forces to help maintain traction and directional control.

Traction Control Function

The traction control function is designed to prevent spinning of the driving wheels on slippery road surfaces, thereby helping to maintain traction and directional control. Activation of this function is shown by flashing the Vehicle Dynamics Control operation indicator light.

Skid Suppression Function

The skid suppression function is designed to help maintain directional stability by suppressing the wheels’ tendency to slide sideways during steering operations. Activation of this function is shown by flashing the Vehicle Dynamics Control operation indicator light.

NOTE

  • The Vehicle Dynamics Control system may be considered normal when the following conditions occur.
    • Slight twitching of the brake pedal is felt.
    • The vehicle or steering wheel shakes to a small degree.
    • An operating sound from the engine compartment is heard briefly when starting the engine and when driving off after starting the engine.
    • The brake pedal seems to jolt when driving off after starting the engine.
  • In the circumstances shown in the following list, the vehicle may be less stable than it feels to the driver. The Vehicle Dynamics Control system may therefore operate. Such operation does not indicate a system malfunction.
    • On gravel-covered or rutted roads
    • On unfinished roads
    • When the vehicle is towing a trailer
    • When the vehicle is fitted with snow tires or winter tires.
  • Activation of the Vehicle Dynamics Control system will cause operation of the steering wheel to feel slightly different compared to that for normal conditions.
  • It is always important to reduce speed when approaching a corner, even if your vehicle is equipped with the Vehicle Dynamics Control system.
  • Always turn off the engine before replacing a tire. Failure to do so may render the Vehicle Dynamics Control system unable to operate correctly.
