Assistance during collision risks limitations

Assistance during collision risks1 has certain limitations that a driver needs to be aware of.

Braking assistance limitations

Extra equipment

Hanging objects, such as a flag or streamer to signal an over-sized load, or extras such as auxiliary lights or front protective grids that extend beyond the height of the vehicle's hood, may obstruct the camera or radar unit.

Slippery road conditions

The extended braking distance on slippery roads may reduce the function's capacity to help avoid a collision. In these types of situations, the Anti-lock Braking System and Electronic Stability Control (ESC2) are designed for optimal braking power with maintained stability.

Low speed

The function is not activated at very low speeds under 4 km/h (3 mph). The system will therefore not intervene in situations in which your vehicle is approaching another vehicle very slowly, such as when parking.

Active driver

The driver's commands are always prioritized. In situations in which the driver is clearly steering and applying the accelerator pedal, the function will not intervene, even if a collision is unavoidable. An active and aware driving style may therefore delay collision warnings and intervention in order to minimize unnecessary warnings.

Steering assistance limitations

The function may have limited functionality in certain situations and not intervene, e.g.:
  • for smaller vehicles such as motorcycles
  • if more than half of your vehicle has moved into the adjacent lane
  • on roads/lanes with indistinct or no side lane markings
  • outside the speed range 60-140 km/h (37-87 mph)
  • when speed-dependent power steering wheel resistance is working at reduced power – e.g. during cooling due to overheating.
Functionality may also be reduced in other situations, such as:
  • road work
  • winter driving conditions
  • narrow roads
  • poor road surfaces
  • a very sporty driving style
  • bad weather with reduced visibility.

In these demanding driving conditions, the function may not be able to properly assist the driver.

Important warnings

 Warning

The driver support system only issues a warning for obstacles detected by its camera and radar units, which means that warnings may come after a delay or not at all.
  • Never wait for a warning or assistance. Apply the brakes when necessary.

 Warning

  • Auto-braking can prevent a collision or reduce collision speed, but to ensure full brake performance the driver should always depress the brake pedal – even when the vehicle brakes automatically.
  • The warning and steering assistance are only activated if there is a high risk of collision – you must therefore never wait for the collision warning or the function to intervene.
  • The function does not activate automatic braking intervention during heavy acceleration.

 Warning

  • Warnings and brake interventions can be triggered late or not at all if the traffic situation or external influences prevent the camera and radar from properly detecting pedestrians, cyclists, large animals or vehicles ahead of the vehicle.
  • To be able to detect vehicles at night, its front and rear lights must work and illuminate clearly.
  • Warnings for stationary or slow-moving vehicles and large animals may be disabled due to darkness or poor visibility.
  • Warnings and brake interventions for pedestrians and cyclists are disengaged at vehicle speeds over 80 km/h (50 mph).
  • The system can provide effective warnings and brake intervention if the relative speed is lower than 50 km/h (30 mph).
  • For stationary or slow-moving vehicles, warnings and brake interventions are effective at vehicle speeds of up to 70 km/h (43 mph).
  • Speed reduction for large animals is less than 15 km/h (9 mph) and can be achieved at vehicle speeds over 70 km/h (43 mph). At lower speeds, the warning and brake intervention for large animals is less effective.

 Note

The function uses the vehicle's camera and/or radar units, which have certain general limitations.
