If the vehicle determines that the driver is unresponsive for a certain amount of time, it can automatically come to a stop within the current lane. This can help avert an accident if the driver suffers a medical emergency while driving, for example.
The vehicle initiates a controlled stop if the driver doesn't respond to requests to actively drive the vehicle. These requests can come from the driver alert feature if the driver is unfocused or shows signs of being too inattentive to drive safely. They may also be related to the driver not keeping their hands on the steering wheel.
Tip
During the stopping maneuver, the vehicle utilizes all of the information it continuously collects about its surroundings to come to a controlled stop in the lane of the road you're on. It also activates the hazard lights to warn other drivers.
If the driver is able to respond after the safe stop maneuver completes, they should move the vehicle to a safe spot where it does not pose a traffic hazard.
Warning
- Driving interventions such controlled emergency stops are supplements to safe driving practices. They do not reduce or replace the need for the driver to stay attentive and focused on driving safely.
- Do not intentionally trigger an emergency stop maneuver if it is not absolutely necessary for stopping safely.
Conditions and limitations
Your vehicle's driver behavior detection system constantly monitors the driver's actions. It relies on interior cameras to keep track of eye movement, attention, drowsiness and whether the driver's hands are on the steering wheel. Emergency stop assist uses information from this system to identify driver actions and decide when an emergency stop is necessary. It is therefore important not to try to trick the behavior monitoring system or cover the cameras.
By disabling distraction alert notifications, you prevent your vehicle from making emergency stops based on input from the distraction alert system. This means that emergency stop assist will not intervene if the driver shows signs of tiredness or a lack of attention. However, ignoring warnings related to the driver not keeping their hands on the steering wheel can still lead to emergency stop interventions.
Emergency stop assist relies on information from the radar and camera units to identify the vehicle's surroundings and perform a safe stop. Read the separate sections about the conditions and limitations of your vehicle's driver behavior detection system, cameras and radar units to understand how features relying on these kinds of detection are affected.
Important
Vehicle faults
If emergency stop assist is unavailable due to a driver support system fault, a message telling you to book a service is shown in the instrument panel. Contact an authorized Volvo workshop if a fault is indicated in this way or another.
Vehicle alterations
Modifications, repairs and accessory installations can negatively affect or limit driver support features. There is a separate manual section with detailed information on this topic.
