by moving the lever forward. Return to low beams by moving the lever toward the steering wheel. The
symbol will illuminate in the instrument
panel when the high beams are on.
Active high beamsThe active high beam system uses a camera at the upper edge of the windshield to detect theheadlights of oncoming vehicles or the taillightsof a vehicle directly ahead. When this happens,the headlights will automatically switch from highbeams to low beams. When the camera no longer detects the head- lights/taillights of other vehicles, your headlightswill switch back to high beams after several sec-onds.
OperationActivate/deactivate this function by turning the ring on the left-side steering wheel lever to
.
If the ring is not in this position, toggling between high and low beams must be done manually. If the ring is turned to another position while the high beams are on, the headlights will automati-cally switch to low beams. A white symbol (
) in the instrument panel
indicates that the function has been activated. When the high beams are on, the symbol will change to blue.
NOTE
•Keep the windshield in front of the cam- era free of ice, snow, dirt, etc.
• Do not mount or in any way attach any-thing on the windshield that couldobstruct the camera.
If a message is displayed in the instrument panel saying that active high beams are temporarilyunavailable, switching between high and lowbeams will have to be done manually. However, the light switch can remain in the
position.
The same applies if a message saying that the windshield sensors are blocked and the
symbol are displayed. The symbol will go
out if this happens. Automatic high beams may be temporarily unavailable (e.g., in heavy fog or rain). When thesystem becomes active again or if the sensors inthe windshield are no longer obscured, the mes- sages will disappear and the
symbol will
illuminate.
WARNING
• Automatic high beams are a driving aid designed to help provide the best possi-ble headlight illumination in good drivingconditions.
• The driver is always responsible for man-ually toggling between high and lowbeams when this is required by traffic orweather conditions.
CAUTION
In the following situations, it may be neces- sary to switch between high and low beamsmanually:
• In heavy fog or rain
• In blowing snow or slush
• In bright moonlight
• In freezing rain
• In areas with dim street lighting
• When oncoming vehicles have dim front lighting
• If there are pedestrians on or near theroad
• If there are reflective objects, such assigns, near the road
• When oncoming vehicles' lights areobscured by e.g., fences, bushes, etc.

DRIVER SUPPORT
274When triggered, City Safety carries out three steps in the following order: 1.
Collision warning
2. Brake assistance
3. Auto-brake
1: Collision warningThe driver is first alerted to the risk of an immi- nent collision. City Safety can detect pedestrians, cyclists or vehicles that are stationary or that are moving inthe same direction as your vehicle. The driver isalerted by a flashing red warning signal, an audi-ble signal and pulsations in the brake pedal.
2: Brake assistanceIf the risk of a collision increases, brake supportwill be activated. This function increases pressure on the brake pedal if the driver does not apply enough pres-sure to the pedal.
3: Auto-brakeThe brakes will be applied automatically. If the driver has not taken action at this stage and a collision is imminent, auto-braking will be trig-gered. Full braking effect will be used to avoidthe collision if possible or to make the speed atthe point of impact as low as possible. In certain situations, auto-braking may begin with limited effect before full braking is used. If City Safety has prevented a collision, the vehi-cle will be kept at a standstill until the drivertakes action. If the vehicle has slowed to avoidcolliding with the vehicle ahead, your speed willbe reduced to that vehicle's speed. When auto-break is triggered, the seat belt pre- tensioners may also be activated, see the article"Seat belts" for additional information. Auto-braking can be cancelled if the driver presses hard on the accelerator pedal. When City Safety applies the brakes, the brake lights will illuminate. When City Safety is triggered and applies the brakes, a text message will be displayed in theinstrument panel.
WARNING
Warnings will only be provided if there is an imminent risk of a collision taking place. Thedriver should be aware of the system's limita-tions before operating the vehicle. Warnings for pedestrians and cyclists will not be provided if the vehicle's speed is above50 mph (80 km/h). City Safety's auto-brake function can help prevent a collision or reduce the speed atwhich a collision occurs. However, the drivershould always apply the brakes, even if auto-brake is operating. The driver is always responsible for maintain- ing the correct speed and distance in relationto the vehicle ahead. Never wait for a collisionwarning or for City Safety to intervene. City Safety maintenance may only be carried out by a trained and qualified Volvo servicetechnician.

City Safety warning level settingsCity Safety is always activated but the function's warning distance can be adjusted.
NOTE
City Safety cannot be turned off and activates automatically each time the engine is started.
Setting a warning level (distance)The distance set for warnings determines the system's responsiveness and sets the distance atwhich visual, audible and tangible (haptic) warn-ings will be triggered. If the driver feels that warnings are given too often, the warning level can be lowered. Thismeans that warnings will be provided later, result-ing in fewer warnings being given. To do so:1. Tap
Settings in the center display's Top
view.
2. Tap
My CarIntelliSafeCity Safety.
3. Choose among
Earlier, Normal or Later.
Begin by choosing
Earlier. If too many warnings
are given, change to Normal.
The setting
Later should only used in exceptional
circumstances, e.g., for a more dynamic driving style.
WARNING
• No automatic system can be guaranteed to function 100% correctly in all situa-tions. For that reason, never test CitySafety by driving toward a person orobject. This could result in serious injuryor death.
• Even if the setting
Earlier has been
selected, warnings may be perceived as being given late, e.g., if the difference inspeed is great or if the vehicle aheadbrakes suddenly.
• City Safety can provide a warning for apotential collision but it can never shortenthe driver's reaction time.
• To help make City Safety as effective as possible, always using the setting
Earlieris recommended.

Detecting cyclists and pedestrians with City Safety
City Safety can detect vehicles, cyclists and pedestrians.
VehiclesCity Safety detects most types of vehicles that are either stationary, moving in the same direc-tion as your vehicle or approaching when you areabout to turn left. In order for City Safety to detect a vehicle in darkness, its headlights and taillights must be onand clearly visible.
Cyclists
Optimal example of what the system considers to be a cyclist: clear body/bike contours
To help function optimally, City Safety's function for cyclist detection needs clear informationabout the bike itself and the rider's head, arms,

DRIVER SUPPORT
276shoulders, legs, the upper and lower parts of the body and a cyclist's normal pattern of movement.
• If major parts of the cyclist's body are not visible to the camera, the system cannotdetect the cyclist.
• The cyclist must be an adult riding an "adult-size" bike.
WARNING
City Safety is designed to be a supplementary driving aid. It cannot detect:
• all cyclists in all situations, e.g., a partially obscured cyclist will not be detected.
• a cyclist whose clothing prevents a clearview of the person's body contours.
• a cyclist transporting a large object.
The driver is always responsible for operating the vehicle in a safe manner.
Pedestrians
Optimal example of what the system considers to be a pedestrian: clear body contours
To help function optimally, City Safety's function for pedestrian detection needs clear informationabout the person's head, arms, shoulders, legs,the upper and lower parts of the body and a per-son's normal pattern of movement. In order to detect a pedestrian, there must be a contrast to the background. If there is little con-trast, the person may be detected late or not atall, which may result in a late or no reaction fromthe system. City Safety can also detect pedestrians in dark- ness with the help of the vehicle's headlights. •
If major parts of the pedestrian's body are not visible to the camera, he/she may not bedetected.
• In order to detect a pedestrian, the systemmust have a full view of the person's entirebody and the person must be at least 32 in.(80 cm) tall.
WARNING
City Safety is designed to be a supplementary driving aid. It cannot detect pedestrians:
• who are partially obscured, wearing cloth- ing that prevents a clear view of the per-son's body contours or who are not atleast 32 in. (80 cm) tall.
• carrying a large object.
The driver is always responsible for operating the vehicle in a safe manner.
