Alarm
The alarm system provides a warning if an attempt is made to break into the vehicle.
The following conditions will trigger the alarm:
• a door/hood/trunk are opened
• the battery is disconnected
• the alarm siren is disconnected
If a problem is detected in the alarm system, this symbol and
Alarm
system failure Service required will
be displayed in the instrument panel.
Do not attempt to repair any of the components in the alarm system yourself; this could affect theinsurance policy on the vehicle. Contact a trainedand qualified Volvo service technician.
NOTE
One of the alarm sensors, which is sensitive to metallic objects, is located under the tunnelconsole cup holders. Avoid leaving coins,keys, etc., in the cup holders because theymay inadvertently trigger the alarm.

Prerequisites
The prerequisites for activating Pilot Assist are:• The driver's seat belt must be buckled and the driver's door must be closed.
• There must be a vehicle ahead (a target vehi-cle) within a reasonable distance or yourvehicle's current speed must be at least9 mph (15 km/h).
With ACC in standby mode: 1. Tap
▶ (6).
> The symbol
will change to Pilot
Assist in standby mode (8).
2. Press the
button (2) on the left-side
steering wheel keypad.
> Pilot Assist will go into active mode and the current speed will be stored and dis- played in the center of the speedometer. or
If Adaptive Cruise Control has been started:
–Tap ▶ (6).
> Pilot Assist will start.
Pilot Assist's steering assis- tance is only active when thesteering wheel symbol (2)changes from GRAY toGREEN.
And Pilot Assist will only regulate the time inter- val to the vehicle ahead when a vehicle symbol(1) is displayed above the steering wheel. At the same time, a speedinterval will be marked. The higher speed is the one stored by the driver and thelower one is the speed of thevehicle ahead (target vehicle).WARNING
Pilot Assist is not a collision avoidance sys- tem. The driver is always responsible forsteering or applying the brakes if the systemdoes not detect another vehicle. Do not use Pilot Assist in demanding driving conditions such as city driving or other heavytraffic situations, in slippery conditions, whenthere is a great deal of water or slush on theroad, during heavy rain or snow, in poor visibil-ity, on winding roads or on highway on- or off-ramps. In certain situations, it may be difficult for Pilot Assist to assist the driver correctly or to deac-tivate automatically. In such cases, it is advisa-ble not to use Pilot Assist. Examples of suchsituations may be:
• the lane's side market lines are missing, badly faded or cross each other.
• the division of lanes is not clear, e.g.,when a line divides or merges withanother, at exits or if there are many roadsigns/markers.
• there are edges or other lines on or nearthe lane, e.g., curbs, cracks, repairedareas, sharp shadows, etc.
• the lane is narrow or winding.

• there are edges or other lines on or nearthe lane, e.g., curbs, cracks, repairedareas, sharp shadows, etc.
• the lane is narrow or winding.
• the lane is at the top of a hill, on anuneven road surface or over a bump.
•bad weather conditions (rain, snow, fog, slush, poor visibility, backlighting, etc).
The driver should also be aware that Pilot Assist has the following limitations: • High curbs, barriers and temporary obsta- cles (cones, barriers etc) may not bedetected or could be detected incorrectlyas side marker lines, which may create arisk of collision. The driver must ensure asafe distance to these obstacles.
• The camera or radar sensor may not beable to detect objects if there are pot-holes or if there are stationary objectspartially or completely blocking the road.
• Pilot Assist does not "see" pedestrians,animals, etc.
• Pilot Assist's steering capacity is limitedand may not always be able to help thedriver keep the vehicle in the lane.
The driver can always take action to override PilotAssist.
Steep roads and/or heavy loadsPilot Assist is primarily intended for use on rela-tively level roads. The function may not be able tomaintain the correct time interval to the vehicleahead on when driving down steep hills. Thedriver should be attentive and prepared to applythe brakes in these situations. Do not use Pilot Assist when the vehicle is trans-porting a heavy load or if it is towing a trailer.
Additional information
•
The Off Road drive mode cannot be
selected if Pilot Assist is activated.
• Pilot Assist uses the vehicle's camera and radar sensor, which have certain general limi-tations. See the articles "Camera limitations"and "Radar sensor limitations" for additionalinformation.

Camera limitations
The camera used by several of the driver support systems has certain limitations, which also affectthe systems using it.
Reduced visibility
WARNING
• The camera has the same limitations as the human eye. In other words, its “visionis impaired” by adverse weather condi-tions such as heavy snowfall, dense fog,etc. These conditions may reduce thefunction of systems that depend on thecamera or cause these systems to tem-porarily stop functioning.
• Strong sunlight, reflections from the roadsurface, ice or snow covering the road, adirty road surface, or unclear lane markerlines may drastically reduce the camera

CauseAction
Water or snow on the surface of the road swirl up and block radar signals or the camera's view. No action. The driver should be extra alert in conditions of this type.
There is dirt between the inside of the windshield and the camera/radar sensor. Have the area of the windshield cleaned by a trained and qualified Volvo service technician.
Strong backlighting No action required. The came will reset automatically when lightingconditions improve.
High temperaturesIf the temperature in the passenger compartment is very high, the camera and radar sensor may betemporarily turned off for approx. 15 minutesafter the engine has been started to protect theirelectronic components. When the temperaturehas cooled sufficiently, the camera and radarsensor will restart automatically.
Damaged windshield
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, usethe 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.

STARTING AND DRIVING
354in countries where it may be difficult to obtain the correct fuel.
• Consider your destination. If you will be driv-ing through an area where snow or ice arelikely to occur, consider using snow tires.
Driving economically
Better driving economy can be obtained by thinking ahead, avoiding rapid starts and stopsand adjusting the speed of your vehicle to imme-diate traffic conditions.
Economical driving conserves natural resources
Observe the following rules: • Bring the engine to normal operating tem- perature as soon as possible by driving witha light foot on the accelerator pedal for thefirst few minutes of operation. A cold engineuses more fuel and is subject to increasedwear.
• Whenever possible, avoid using the vehiclefor driving short distances. This does notallow the engine to reach normal operatingtemperature.
• Drive carefully and avoid rapid accelerationand hard braking.
• Use the transmission's Drive (
D) position as
often as possible and avoid using kick-down.
• Using the engine's Eco function can helpimprove fuel economy.
• Do not exceed posted speed limits.
• Avoid carrying unnecessary items (extra load)in the vehicle.
• Maintain correct tire pressure. Check tirepressure regularly (when the tires are cold). •
Use tires recommended by Volvo for yourvehicle.
• Remove snow tires when threat of snow orice has ended.
• Note that roof racks, ski racks, etc, increaseair resistance and also fuel consumption.
• At highway driving speeds, fuel consumptionwill be lower with the air conditioning on andthe windows closed than with the air condi-tioning off and the windows open.
• Using the onboard trip computer's fuel con-sumption modes can help you learn how todrive more economically.
Other factors that decrease gas mileage are:
• Dirty air cleaner
• Dirty engine oil and clogged oil filter
• Dragging brakes
• Incorrect front end alignment
Some of the above mentioned items and othersare checked at the standard maintenance inter-vals.
Handling and roadholding
• Vehicle load, tire design and inflation pres-sure all affect vehicle handling. Therefore,check that the tires are inflated to the rec-ommended pressure according to the vehicleload. Loads should be distributed so that
