2022 Volvo XC40 Driver support
Driving support systems
For example, the systems can help the driver to:
- maintain a set speed
- maintain a certain time interval to the vehicle ahead
- prevent a collision by giving a warning to the driver and breaking the car
- help the driver to park.
Some of the systems are fitted as standard while others are options – which alternative applies is market dependent.
The driver support systems are only supplementary aids – they cannot handle all situations in all conditions.
The driver always bears responsibility that the vehicle is driven safely and that applicable road traffic rules and regulations are followed.
Safety check of driver support when starting
The safety check is shown in the driver’s display
The illustration shows the 12″ driver display
The illustration shows the 8″ driver displayThe green dots indicate that everything looks OK. If any system needs an additional check, this is shown by an orange dot and a message in the driver display.
Available driver support systems may vary depending on the market, options, car model, and model year.
Warnings from various driver support systems
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. You have the option of viewing a list of some of the functions and what they may do – the aim of this is to ensure you are not surprised by the activation of any of the functions. If a function should be activated, you can also be informed of this via a text message in the driver display.
Read the individual sections on each system in order to fully understand the functions and learn about important warnings.
Warning with the symbol, acoustic signals, visual signals, or vibration
The driver support functions in your car can alert you in different ways. For example, with vibration in the steering wheel, brake pulse, visual or acoustic signals, or via symbols in the driver display.
City Safety™
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 react to him/herself within a reasonable amount of time.
Steering assistance at risk of collision
The function of 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.
Your experience of the function may therefore differ depending on which of the subfunctions is activated.
- Steering assistance upon the risk of run-off.
- Steering assistance upon the risk of a head-on collision.
- Steering assistance upon the risk of rear-end collision.
Lane Keeping Aid (LKA)
Lane assistance can help 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.
- Steering assistance: If the function detects that the car is approaching a lane line, you will feel a gentle steering action applied to the steering wheel. 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 alerted by vibration in the steering wheel.
- Both: You are alerted to vibration and a gentle steering action is applied to the steering wheel.
Blind Spot Information (BLIS)
BLIS is designed to give a warning of rapidly approaching vehicles as well as vehicles diagonally behind and to the side of your vehicle so as to give you assistance in heavy traffic on roads with several lanes in the same direction.
- Alerts with an indicator lamp in the side mirror, with a fixed glow and flashing light.
Driver Alert
The function is intended 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 a message.
Cross Traffic Alert (CTA)
Cross Traffic Alert is a function designed to alert for crossing traffic when the car is being reversed.
- Acoustic signal from the left or right-hand speaker, depending on the direction from which the object is approaching
- The icon in the driver display
- The icon in the park assist camera’s top view
Roll Stability Control (RSC)
Roll Stability Control is a stabilizer system that, in certain situations, can help to reduce the risk of overturning, for example, during sudden evasive maneuvers 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.
Warning
The functions described are supplementary aids – they cannot handle all situations in all conditions.
The driver always bears responsibility that the vehicle is driven safely and that applicable road traffic rules and regulations are followed.
Speed-dependent steering force
Reduced power
In rare situations, the power steering may need to work at reduced power, and turning the steering wheel may then seem slightly heavier. This may occur when the power steering becomes too hot and it then needs temporary cooling. It may also occur if the power supply is disrupted.
In the event of reduced power, the message Power steering Assistance temporarily reduced is shown, as well as this symbol in the driver display. While the power steering is working at reduced power, the driver support functions and steering assistance systems are not available.
If the temperature increases too much, the servo may be forced to switch off completely. In such a situation, the driver display shows the Power steering failure Stop safely message, combined with a symbol.
Change the steering force level
- Steering wheel resistance can be adjusted when using INDIVIDUAL drive mode.
- Tap on Settings in the center display’s top view.
- Select .
- Steering wheel resistance selection can only be accessed if the car is stationary or is moving at low speed and in a straight line.
Drive modes when using time intervals for vehicles
- The driver can select different driving styles for how driver support should maintain the preset time interval to the vehicle ahead.
- Selection is made via the drive mode control DRIVE MODE.
- Select one of the following options:
- Eco – The driver support focuses on good fuel economy, which means longer time intervals to the vehicle ahead.
- Comfort – The driver support focuses on following the set time interval to the vehicle ahead as smoothly as possible.
- Dynamic – The driver support focuses on following the set time interval to the vehicle ahead more closely, which in certain cases may mean heavier acceleration and braking.
Auto braking after a collision
- In the event of a collision in which the activation level is reached for the pyrotechnic seatbelt tensioners or airbags, or if a collision with a large animal is detected, the car’s brakes are automatically applied.
- This function is to prevent or reduce the effects of any subsequent collision.
- After a serious collision, there is a risk that it is no longer possible to control and steer the car.
- In order to avoid or mitigate a possible further collision with a vehicle or an object in the vehicle’s path, the auto braking system is activated automatically and brakes the car in a safe manner.
- Brake lights and hazard warning lights are activated during braking.
- When the car has stopped, the hazard warning lights continue to flash and the parking brake is applied.
- If braking is not appropriate, e.g. if there is a risk of being hit by the following traffic, the system can be overridden by the driver depressing the accelerator pedal.
- The function assumes that the brake system is intact after the collision.
