Radar sensor limitations
The radar sensor used by several of the driver support systems has certain limitations, whichalso affect the systems using it.
Obstructions
The marked area must not be obstructed in any way. This area of the windshield should always be kept clean
The radar sensor is located at the upper, center section of the windshield along with the camera.
WARNING
Never place any objects, decals, etc., on the windshield in front of the camera/radar unit.This could reduce or block these components'functions, and could cause one or more of thesystems that utilize the them to stop function-ing.
If this symbol and
Windscreen
sensor Sensor blocked, see
Owner's manual appear in the instru-
ment panel, this indicates that the
camera and/or radar sensor cannot detect other vehicles ahead.
The following table shows some of the situations that can cause the message to be displayed andsuggested actions.
CauseAction
The area of the windshield in front of the camera/radar sensor is dirty or covered by ice or snow.Clean the windshield or remove the ice/ snow.
Thick fog or heavy rain/snow blocks reduces the camera/radar sensor's range of visibility.No action. The driver should be extra alert in conditions of this type.

Setting an Adaptive Cruise Control time interval
ACC makes it possible to set various time inter- vals to the vehicle ahead.
Different time intervals to the vehicle ahead can be selectedand are shown in the instru-ment panel as 1–5 horizontalbars. The greater the number ofbars, the longer the time inter-val. One bar between the vehi-
cles represents a time interval of approximately1 second; 5 bars is approximately 3 seconds. The same symbol appears if Distance Alert is activated.
• If the symbol shows two vehicle's, ACC is actively following the vehicle ahead.
• If only one vehicle is displayed, ACC is
not
actively following another vehicle.

Adaptive Cruise Control (ACC) - fault tracing
ACC is an optional system designed to assist the driver by maintaining a set speed or a settime interval to the vehicle ahead.
If this symbol is displayed in the instru- ment panel and the message
Windscreen sensor Sensor
blocked, see Owner's manual
appears, the ACC radar sensor is blocked and cannot detect vehicles ahead.
This message also indicates that the following systems may have reduced functionality:
• Distance Alert
• City Safety
• Driver Alert Control
• Pilot Assist
• Lane Departure Warning (LDW)
• Lane Keeping Aid (LKA)
• Traffic Sign Information (TSI) The following table lists possible causes for thismessage being displayed and suitable actions:
CauseAction
The windshield in front of the radar is dirty or covered with snow/ice.Clean/clear the windshield in front of the radar.
Heavy rain or snow is interfering with the radar signals.No action possible. Heavy precipitation may affect the function of the radar.
Swirling water or snow from the surface of the road may interfere with the radar signals.No action possible. A very wet or snow-covered road surface may affect the function of the radar.
The windshield in front of the radar is clean but the message remains in the display.Wait a short time. It may take several minutes for the radar to detect that it is no longer obstructed.
A text message can be erased by briefly pressing the
O button on the right-side steering wheel

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.
