City Safety when evasive action is not possible
City Safety can help the driver by automatically braking the vehicle sooner if it is not possible tosteer out of a potential collision situation.
City Safety assists the driver by continuously try- ing to determine possible "escape routes" to thesides if a slow-moving or stationary vehicle aheadis detected at a late stage.
Your vehicle (1) cannot "see" any way of veering to avoid the vehicle ahead (2) and will attempt to auto-brake sooner
Your vehicle
Slow moving/stationary vehicle
City Safety will not trigger the auto-brake func- tion as long as the driver has a chance to avoid acollision by steering the vehicle. However, if City Safety determines that an eva-sive steering maneuver is not possible due to alack of space in the adjacent traffic lanes, thefunction will attempt to assist the driver by auto-matically applying the brakes considerablysooner.
WARNING
City Safety's capacity to assess certain traffic situations is a supplemental aid to the driverand does not function in all driving/traffic sit-uations or weather/road conditions. It cannever replace the driver

The following table shows some of the situations that can cause the message to be displayed andsuggested actions.
Cause
Action
The area of the wind- shield in front of thecamera/radar sensor isdirty or covered by ice orsnow. Clean the wind-shield or removethe ice/ snow.
Thick fog or heavy rain/snow blocks reduces thecamera/radar sensor'srange of visibility. No action. Thedriver should beextra alert in condi-tions of this type.
There is dirt betweenthe inside of the wind-shield and the camera/radar sensor. Have the area ofthe windshieldcleaned by atrained and quali-fied Volvo servicetechnician.
CAUTION
•
Service and maintenance on City Safety may only be carried out by a trained andqualified Volvo service technician.
• If a crack, scratch or stone chip shouldoccur in the section of the windshield infront the camera/radar sensor, contact atrained and qualified Volvo service techni-cian to repair or replace the windshield.Failing to do so may result in reducedCity Safety functionality.
• This can also result in certain functionsbeing reduced or disabled, or they mayrespond incorrectly.
To help avoid the risk of incorrect, reduced ordisabled functionality for driver support sys-tems using the camera or radar sensors:
• Volvo recommends that cracks, scratchesor stone chips on the windshield in front of the camera/radar sensor should
not
be repaired; in such cases, the entire windshield should be replaced.
• Before the windshield is replaced, con-tact a Volvo retailer to ensure that thecorrect windshield is ordered and instal-led. If the wrong type of windshield isused, this may cause City Safety to func-tion improperly or not at all.
• Volvo recommends the use of only Genu-ine Volvo Replacement Windshields.
• When replacing windshield wipers, use the same type or ones approved by Volvo.
After the windshield has been replaced, thecamera/radar sensor will have to be recalibra-ted by a trained and qualified Volvo servicetechnician to help ensure proper function ofall of the vehicle's camera-/radar-based sys-tems.
MaintenanceIn order for City Safety to function properly, the area of the windshield must be kept free of dirt,ice, snow, etc.
Other vehicle functionsIf a message is displayed in the instrument panel,this means that the other systems using the cam-era/radar sensor (see the list below) will not havefull functionality or may not function at all. The camera and radar sensor is used by the fol- lowing functions: • Distance Alert
*
• Driver Alert Control
*
• Adaptive Cruise Control
*
• Pilot Assist
*
• Run-off Mitigation
• Road Sign Information
*
• Active High Beams

Driving lane assistance provides vibrations in the steer- ing wheel7
.
Depending on the settings used, Lane Keeping Aid functions in different ways:
• Assistance type
Assist8
is activated: when
the vehicle approaches a traffic lane marker line, LKA will provide active steering assis-tance to help steer it back into the lane.
• Assistance type
Warning8
is activated: if the
vehicle is moving out of its traffic lane, an audible signal and/or vibrations in the steer-ing wheel will be provided.
NOTE
If the turn signal is used, Lane Keeping Aid will not provide an alert or steering assis-
tance.
WARNING
Lane Keeping Aid is only intended to assist the driver and does not function in all driving,weather, traffic or road conditions. As the driver, you have full responsibility for operating the vehicle in a safe manner.
Steering assistanceIn order for LKA's steering assistance to function, the driver's hands must be on the steering wheel,which the system monitors continuously.
If the driver's hands are not onthe steering wheel, this symbolwill illuminate in the instrumentpanel and the following mes-sage will be displayed:
•Lane Keeping Aid – Apply steering
If the driver does not begin to steer the vehicle, the symbol will illuminate again, an audible signal will sound and the following message will be dis-played:
•
Lane Keeping Aid – Standby until
steering applied
If the driver still does not begin to steer the vehi- cle, LKA will go into standby mode. The functionwill not become available again until the driveractively steers the vehicle
Traffic lane assistance does not react
The traffic lane assistance system does not intervene in sharp curves
In certain cases, such as during active driving or if the turn signal is used, the traffic lane system will not react if the vehicle crosses a lane marker
line.
7 The level of vibrations varies; the farther the vehicle is over a lane marker line, the greater the number of vibrations:
8 See "Type of assistance" in the article "Activating/deactivating Lane Keeping Aid".

Driving lane assistance symbols and messages
A number of symbols and messages relating to Lane Keeping Aid (LKA) may appear in theinstrument panel.
Symbols in the instrument panelThe driving lane assistance systems use a symbol in theinstrument panel in differentsituations.
Several examples of the symbol's appearance will be given here:
Available
When the driving lane assistance systems are available,
the marker lines in the symbol will be white.
LKA are monitoring the driving lane's marker line(s).
Not available
When the driving lane assistance systems are not avail-
able, the marker lines in the symbol will be gray
This is because LKA cannot monitor (detect) the driving lane's marker line(s) or the vehicle'sspeed is too low or the road is too narrow.
Steering/warning indicator
Steering/warning: the side marker lines in the symbol will be colored
LKA indicates that the system is warning and/or attempting to steer the vehicle back into its lane.
