2022 Volvo S90 Exterior lighting
Active bending lights
(Option/accessory)
Active bending lights are designed to provide additional illumination in bends and junctions. Cars with LED (LED (Light Emitting Diode)) headlamps (Option/accessory.) can have active bending lights, depending on the car’s equipment level.
Headlamp pattern without active bending lights (left) and with active bending lights (right). Active bending lights follow steering wheel movements to provide additional illumination in bends and junctions and can thereby provide the driver with improved visibility. In the event of a fault in the function, the
symbol illuminates in the driver display at the same time as the driver display shows an explanatory text. The active bending lights are only switched on in weak daylight or in darkness as well as when the stalk switch’s rotating ring is in 
position. The car also needs to be in motion with the dipped beam activated.
Active main beam
Active main beam uses the camera sensor in the upper edge of the windscreen. The camera sensor registers the headlamp beams from oncoming traffic or the rear lights of vehicles ahead, and then switches from main beam to dipped beam.
The symbol
represents active main beam.The function can start while driving in the dark when the car’s speed is approx. 20 km/h (approx. 12 mph) or higher. The function can also take streetlights into account. When the camera sensor no longer detects any oncoming car or car in front, main beam is switched on again after about a second.
Activate active main beam
Active main beam is activated and deactivated by turning the left-hand stalk switch to position . The rotating ring then returns to position . When active main beam is activated, the symbol 
illuminates with a white glow in the driver display. When main beam is activated, the symbol shines blue. If active main beam is deactivated while main beam is on, the lighting is immediately reset to dipped beam. Active main beam does not need to be reactivated every time the car is started.
Adaptive functionality
The active main beam has adaptive functionality.(Depending on the car’s equipment level.) In this case, unlike what happens during conventional dimming, the light beam continues to illuminate with main beam on both sides of oncoming traffic or vehicles ahead – only the part of the light beam that points directly to the vehicle is dimmed.
Adaptive functionality: Dipped beam directly towards oncoming vehicle, but continued main beam on both sides of the vehicle.
The main beam is partly dimmed, i.e. if the light beam shines with slightly more than dipped beam, the symbol in the driver display shines blue. On motorways or at high speed, the system may change from adaptive to automatic functionality.
The camera sensor on which the function is based has limitations.
If this symbol is shown in the driver display, together with the message Active High Beam Temporarily unavailable, then switching between main and dipped beam must be performed manually.
The same applies if this symbol is shown together with the message Windscreen sensor blocked See Owner’s manual. Active main beam may be temporarily unavailable e.g. in situations with dense fog or heavy rain. When active main beam becomes available again, or the windscreen sensors are no longer blocked, the message is extinguished and active main beam is reactivated.
Active main beam is an aid for using the optimum beam pattern when conditions are favourable. The driver always bears responsibility for manually switching between main and dipped beam when traffic situations or weather conditions so require.
Using direction indicators
The car’s direction indicators are operated with the left-hand stalk switch. The direction indicator lamps flash three times or continuously, depending on how far up or down the stalk switch is moved.
Direction indicators.
Short flash sequence
| 1 | Move the stalk switch up or down to the first position and release. The direction indicator lamps flash three times. |
Note
- This automatic flashing sequence can be stopped by moving the stalk switch immediately in the opposite direction.
- If the symbol for direction indicators in the driver display flashes more quickly than normal – see the message in the driver display.
Continuous flash sequence
| 2 | Move the stalk switch up or down to its end position. |
The stalk switch remains in its position and is moved back manually, or automatically by the steering wheel movement.
Brake lights
The brake light automatically comes on during braking. The brake light is illuminated when the brake pedal is depressed and when the car is braked automatically by one of the driver support systems.
Rear fog lamp
The rear fog lamp is considerably stronger than the normal rear lights and should only be used in reduced visibility due to fog, snow, smoke or dust so that other road users have an early warning of a vehicle ahead.
Button for rear fog lamp. The rear fog lamp is a lamp at the rear of the car, on the driver’s side. The rear fog lamp can only be switched on when:
- ignition position II is active and the rotating ring on the stalk switch is in position or
- the stalk switch’s rotating ring is in position
and the front fog lamps are switched on.
Press the button to switch the lights on/off. The 
symbol in the driver display illuminates when the rear fog lamp is switched on. The rear fog lamp is switched off automatically when:
- the car is switched off or when the rotating ring on the stalk switch is set to the
position - the stalk switch’s rotating ring is in position
and the front fog lamps are switched off.
Regulations on the use of rear fog lamps vary from country to country.
Front fog lamps/cornering lights
(Option/accessory)
The front fog lamps are activated manually when driving in fog and automatically when reversing in order to complement the reversing light. If the car is fitted with cornering lights,(Option/accessory.) the front fog lamps come on automatically in dull daylight or darkness in order to light up the area diagonally in front of the car.
Button for front fog lamps.
The front fog lamps can only be switched on when the car’s electrical system is in ignition position II and the rotating ring on the stalk switch is in position , or . Press the button to activate and deactivate. The 
symbol illuminates in the driver display when the front fog lamps are switched on. The front fog lamps switch off automatically when the car is switched off or when the rotating ring on the stalk switch is set to the position.
Regulations on the use of fog lamps vary from country to country.
Cornering lights (Option/accessory.)
The function is activated in weak daylight or darkness when the stalk switch’s rotating ring is in the or position and the speed of the car is lower than approx. 30 km/h (approx. 20 mph).
In addition, both cornering lights are switched on as a supplement to the reversing lamp during reversing. They are extinguished when the car drives forward again.
Dipped beam
When driving with the stalk switch’s rotating ring in the position, dipped beam is activated automatically in weak daylight or darkness or when the car’s electrical system is in ignition position II.
Stalk switch rotating ring in AUTO position.
With the stalk switch’s rotating ring in position, dipped beam is also activated automatically if:
- the front fog lamps (Option/accessory.) are activated
- the rear fog lamp is activated
- the front and rear fog lamps are activated
With the stalk switch’s rotating ring in the position, dipped beam is always activated when the car’s electrical system is in ignition position II.
The car detects when it is driven into a tunnel and switches from daytime running lights to dipped beam. Note that the rotating ring in the left-hand stalk switch must be in
mode for tunnel detection to work.Using main beam
Main beam is operated with the left-hand stalk switch. Main beam is the car’s strongest lighting and should be used when driving in the dark for better visibility, as long as it does not dazzle other road users.
Steering wheel stalk switch with rotating ring.
Main beam flash
| 1 | Move the stalk switch backwards slightly to main beam flash position. Main beam comes on until the stalk switch is released. |
Main beam
| 2 | Main beam can be activated when the steering wheel stalk switch’s rotating ring is in position or . Activate main beam by moving the stalk switch forwards. |
| 3 | Deactivate by moving the stalk switch backwards. |
When main beam has been activated, it can be deactivated by moving the stalk switch backwards to either 1 position or 3 position.
When main beam has been activated the symbol illuminates in the driver display.
Using home safe lighting
Some of the exterior lighting can be kept switched on to work as home safe lighting after the car has been locked.
To activate the function:
- Make sure the car is switched off.
- Move the left-hand stalk switch forward toward the instrument panel and release.
- Get out of the car and lock the door.
- A symbol in the driver display is illuminated to indicate that the function is activated and outer lighting is switched on: Position lamps, headlamp beams, number plate lighting and lighting in outer handles. (Option/accessory.)
The home safe lighting is illuminated for approximately 60 seconds.
Adapting the headlamp pattern from the headlamps
This car does not need to reset the headlamp pattern when changing from right to left-hand traffic, and vice versa.
Emergency brake lights
Emergency brake lights are activated to alert vehicles behind about heavy braking. The function means that the brake light flashes instead of – as in normal braking – shining with a constant glow. The emergency brake lights are activated during heavy braking or if the ABS system is activated at high speeds. After the driver brakes to a low speed and then releases the brake, the brake light returns to normal function and is extinguished. The car’s hazard warning flashers are activated at the same time. These flash until the driver accelerates the car to a higher speed again or switches off the car’s hazard warning flashers.
Position lamps
Position lamps can be used so that other road users can see the car if it stops or is parked. The position lamp is switched on with the rotating ring on the stalk switch.
Stalk switch rotating ring in position lamps position. Turn the rotating ring to the
position – the position lamps are switched on (number plate lighting is switched on at the same time). If the car’s electrical system is in ignition position II then the daytime running lights are switched on instead of the front position lamps. When the rotating ring is in this position, the rear position lamps are switched on regardless of the ignition position of the car’s electrical system. If the car is stationary but running, the rotating ring can be moved to the position lamp position from another position to switch on only the position lamps instead of other lighting. When driving for more than 30 seconds at max. 10 km/h (approx. 6 mph), or if the speed exceeds 10 km/h (approx. 6 mph), the daytime running lights are switched on. The driver should turn to a position other than . If the boot lid is opened when it is dark outside, the rear position lamps are switched on (if not already switched on) to warn road users approaching from behind. This takes place irrespective of the position of the rotating ring or the ignition position of the car’s electrical system.The rear position lamps have an adaptive function. The brightness of the rear position lamps is adapted depending on the light conditions in the surroundings. When it is light outside, the rear position lamps are illuminate more brightly to make them more visible to other vehicles. When it is dark outside, the rear position lamps illuminate less brightly to avoid dazzling other vehicles. Number plate lighting and trailer lighting are not affected by the adaptive function.
Guidance light
The guidance light is switched on when the car is unlocked and is used to switch on the car’s lighting at a distance. The function is activated when the car is unlocked. In daylight, position lamps, interior roof lamps, floor lights and cargo area lighting are activated. In weak daylight or darkness, number plate lighting and lighting in the outer handles are also activated (Option/accessory.) with their light source aimed towards the ground. The lighting stays on for approx. 2 minutes if no doors are opened. If a door is opened within the activation time, the time for the interior lighting and lighting in the outer handles will be (Option/accessory.) extended. The function can be activated and deactivated via the centre display.
Hazard warning flashers
Hazard warning flashers warn other road users by means of all of the car’s direction indicators being activated simultaneously. The function can be used to give a warning in the event of traffic hazards.
Button for hazard warning flashers. Press the button to activate the hazard warning flashers. The hazard warning flashers are automatically activated when the car brakes so powerfully that the emergency brake lights are activated and the speed is low. The hazard warning flashers start to flash after the emergency brake lights have stopped flashing and are then deactivated automatically when the car drives away again or are deactivated if the button is depressed. The hazard warning flashers are automatically activated in the event of a collision.
Regulations for the use of hazard warning flashers may vary between countries.
Daytime running lights
The car has sensors that detect the light conditions in the surroundings. The daytime running lights are switched on when the rotating ring on the stalk switch is in position , or as well as when the car’s electrical system is in ignition position II. In position , the headlamps change automatically to dipped beam in weak daylight or darkness.
Stalk switch rotating ring in AUTO position.
If the stalk switch rotating ring is in the position, the daytime running lights (DRL) (Daytime Running Lights) are switched on when the car is driven in daylight. The car automatically changes lighting from daytime running light to dipped beam in weak daylight or darkness. Changing to dipped beam also takes place if the front fog lamp (Option/accessory.) and/or rear fog lamp are activated.
This system help to save energy – it cannot determine in all situations when daylight is too weak or sufficiently strong, e.g. in mist and rain. The driver is always responsible for ensuring that the car is driven with the correct beam pattern for the traffic situation and in accordance with applicable traffic regulations.
Checking trailer lamps
(Option/accessory)
When connecting a trailer – check that the trailer lamps work before departure.
Checking trailer lamps
(Option/accessory)
