How do I notice that a safety function has been activated?

If you notice that the car acts of its own accord in an unexpected way then this may be due to one of the car's safety-related functions being activated.

What is happening in your car?

There are several functions in your car that can contribute actively to increasing safety in traffic, both for yourself and other road users. In order that you should not be surprised if any of the functions are activated, you have the option here of seeing an overview of the different functions and how they may act in a critical situation. If a function should be activated, you can also be informed on this via a text message in the driver display.

 Note

The functions are briefly described below. For more detailed information and important warnings regarding functions, etc., see the Owner's Manual for your car model.

Some of the car's systems are fitted as standard while others are options. This may vary depending on market, model year and car model.

You can be alerted by symbols, acoustic signals, light signals or vibration

The safety functions in your Volvo can alert you in different ways. For example, with vibration in the steering wheel, brake pulse warnings, with visual or acoustic signals or via symbols in the driver display or head-up display1. Below you can read about the safety functions and how they can alert you.

Blind Spot Information

16w17 - Support site - Blind spot information (Symbol)

Blind Spot Information, BLIS, is designed to give a warning of rapidly approaching vehicles as well as vehicles diagonally behind and to the side of your car in order to give assistance in heavy traffic on roads with several lanes in the same direction.

16w17 - Support Site - Blind spot information (mirror)

BLIS gives a warning with an indicator lamp in the door mirror, with a constant glow and flashing light.

City Safety™

16w17 - Support site - City Safety (Symbol)

City Safety is a function that can prevent or mitigate a collision with pedestrians, cyclists, larger animals or vehicles. Visual, acoustic and brake pulse warnings are given in the event of a risk of collision to help the driver act in time. If the driver does not react to the warning and the risk of collision is assessed as imminent then City Safety can automatically brake the car.

  • Brake pulse warnings, visual and acoustic signals.
  • The car brakes in certain situations if the driver does not act within a reasonable time.

Cross Traffic Alert

16e17 - Support site - Cross Traffic Alert (Symbol)

Cross Traffic Alert, CTA, is a function designed to warn about crossing traffic when the car is being reversed2.

  • Acoustic signal from left or right-hand speaker, depending on the direction from which the object is approaching.
  • Icon in the driver display.
  • Icon in the park assist camera's top view.

Distance Warning3

16w17 - Support site - Distance Alert - Head-up Display

Distance Warning4 can warn you if you are not far enough away from the vehicle in front of you.

  • If the distance to the vehicle in front of you becomes too short according to the preset value, a warning light and/or a symbol is shown in the windscreen. For the car to include the function, it must be equipped with a Head Up Display5.

Driver Alert Control

16w17 - Support Site - Driver Alert Control - (Display)

Driver Alert Control, DAC, is designed to attract the driver's attention if he/she starts to drive less consistently, e.g. if he/she becomes distracted or starts to fall asleep.

  • Acoustic signal combined with a symbol in the driver display and the message Time for a break soon?.

Lane assistance

16w17 - Support Site - Lane Keeping Aid (Symbol)

Lane assistance, LKA6, can assist you to reduce the risk of the car unintentionally leaving its own lane. Since you have the option to choose the setting for how the function should assist you, your experience of the safety function may vary.7

  • Steering assist: If the function detects that the car is approaching a lane line, you will feel a gentle steering action applied to the steering wheel. Remember that you must have both hands on the steering wheel for the function to work.
  • Warning: If the function detects that the car is approaching a lane line, you will be warned by vibration in the steering wheel.
  • Both: You are warned with vibration and a gentle steering action applied to the steering wheel.

Collision avoidance assistance

The function for collision avoidance assistance can help you reduce the risk of the car unintentionally leaving its lane and/or colliding with another vehicle or obstacle. The function can assist you by helping to steer the car back into its own lane and/or steer aside.8

When you start the function, three subfunctions are activated which can help in different situations. Your experience of the function may therefore differ slightly depending on which of the subfunctions is activated.

  • Steering assist with run-off mitigation: If the camera detects that the car is about to cross the edge of the road, you may feel that the function is attempting to steer the car back into its own lane. If the steering intervention is assessed as insufficient, the function will also attempt to brake the car. There will be no steering or brake intervention if you have activated the direction indicators, and if the function assesses that the car is being driven actively by you as the driver, activation of the function will be held back.
  • Steering assistance upon risk of head-on collision: If the car is about to leave its own lane while an oncoming vehicle is approaching at the same time, the function can help you as the driver to steer the car back into its own lane by means of steering intervention. There will be no steering or brake intervention if you have activated the direction indicators, and if the function assesses that the car is being driven actively by you as the driver, activation of the function will be held back.
  • Steering assist upon risk of rear-end collision9: If the car is about to leave its own lane while another vehicle is diagonally behind, in the blind spot or is approaching rapidly from behind, the function can help you to steer the car back into its own lane. Even if the direction indicators are activated and you actively steer the vehicle, the function can assist with steering intervention.

Rear Collision Warning3

16w17 - Support Site - Rear Collision Warning

Rear Collision Warning, RCW, is a system that can help you avoid being hit by a vehicle approaching from behind. If the system detects a risk of rear-end collision, it can give a warning and take the following action, depending on the conditions:

  • Intensive flashing with the direction indicators.
  • At low speeds RCW can tension the seatbelts by activating the seatbelt tensioners, and activate the Whiplash Protection System.
  • If the car is stationary, the foot brake can be activated

Roll Stability Control10

16w17 - Support site - Roll stability control symbol

Roll Stability Control, RSC, is a stabiliser system that, in certain situations, can help to reduce the risk of overturning, for example, during sudden evasive manoeuvres or if the car skids. If the system registers that there is a risk of the car overturning, it can react with the following action:

  • Engine torque is reduced.
  • One or more wheels are braked.

Whiplash Protection System (WHIPS)

WHIPS is a function that can protect against whiplash injuries. The system consists of energy absorbing backrests and seat cushion, as well as a specially designed head restraint in the front seats.
