338and lower body in combination with normal human movements. If large portions of the cyclist's body or the bicy- cle itself are not visible to the function's camera,it will not be able to detect a cyclist. The system can only detect adult cyclists riding on bicycles intended for adults.
WARNING
City Safety is supplementary driver support, but it cannot detect all cyclists in all situationsand, for example, cannot see:
• partially obscured cyclists.
• cyclists if the background contrast of the cyclist is poor - warning and brake inter-ventions may then be late or not occur atall.
• cyclists in clothing that hides their bodycontour.
• bikes loaded with large objects.
The driver is always responsible for ensuring that the vehicle is driven correctly and with asafety distance suitable for the speed.
Pedestrians
Optimal examples of what the system considers to be a pedestrian: clear body contours.
For optimal performance, the system's function for pedestrian detection needs the clearest pos-sible information about body and bicycle con-tours. This entails being able to detect the con-tours of the pedestrian's head, arm, shoulders,legs, torso and lower body in combination withnormal human movements. In order to detect a pedestrian, there must be a contrast to the background, which could dependon clothing, weather conditions, etc. If there is lit-tle contrast, the person may be detected late ornot at all, which may result in a delayed reactionfrom the system or no reaction at all. City Safety can detect pedestrians even in dark conditions if they are illuminated by the vehicle'sheadlights.
WARNING
City Safety is supplementary driver support, but it cannot detect all pedestrians in all sit-uations and, for example, cannot see:
• partially obscured pedestrians, people in clothing that hides their body contour orpedestrians shorter than 80 cm (32 in.).
• pedestrians if the background contrast ofthe pedestrians is poor - warning andbrake interventions may then be late ornot occur at all.
• pedestrians who are carrying largeobjects.
The driver is always responsible for ensuring
that the vehicle is driven correctly and with a safety distance suitable for the speed.

Large animals
Optimal examples of what City Safety would interpret as a large animal: stationary or moving slowly and with clearbody contours.
For optimal performance, the system's function for detecting large animals (e.g. moose, horses,etc.) needs the clearest possible informationabout body contours. This entails being able todetect the animal straight from the side in combi-nation with normal movements for that animal. If parts of the animal's body are not visible to the function's camera, the system will not be able todetect the animal. City Safety can detect large animals even in dark conditions if they are illuminated by the vehicle'sheadlights.
WARNING
City Safety is supplementary driver support, but it cannot detect all large animals in all sit-uations and, for example, cannot see:
• partially obscured larger animals.
• larger animals seen from the front or from behind.
• running or fast moving larger animals.
• larger animals if the contrast of the ani-mal's background is poor - warning andbrake interventions may then occur lateor not at all.
• smaller animals such as cats and dogs.
The driver is always responsible for ensuring that the vehicle is driven correctly and with asafety distance suitable for the speed.

City Safety in crossing traffic
City Safety can assist the driver when turning in the path of an oncoming vehicle in an intersec-tion.
: Sector in which City Safety can detect an oncoming
vehicle in crossing traffic.
In order for City Safety to detect an oncoming vehicle in situations where there is a risk of a col-lision, that vehicle must be within the sector inwhich City Safety can analyze the situation. The following criteria must also be met:
• your vehicle's speed must be at least 4 km/h (3 mph)
• your vehicle must be making a left turn
• the oncoming vehicle's headlights must beon

WARNING
•The "City Safety in crossing traffic" func- tion is supplementary driver supportintended to improve driving safety – itcannot handle all situations in all traffic,weather and road conditions.
• Warnings and brake interventions due toa collision risk with an oncoming vehicleoften come very late.
• Never wait for a collision warning or forCity Safety to intervene.
• City Safety is not a substitute for the driv-er's attention and judgment. The driver isalways responsible for ensuring the vehi-cle is driven in a safe manner, at theappropriate speed, with an appropriatedistance to other vehicles, and in accord-ance with current traffic rules and regula-tions.

Limitations of City Safety incrossing traffic
In certain situations, it may be difficult for City Safety to help the driver avoid a collision withcrossing traffic.
For example:
• on slippery roads when Electronic Stability Control (ESC) is actively operating
• if an approaching vehicle is detected at a latestage
• if the oncoming vehicle is partially obstructedby another vehicle or object
• if the oncoming vehicle's headlights are off
• if the oncoming vehicle is moving erraticallyand e.g. suddenly changes lanes at a latestage.
NOTE
The function uses the vehicle's camera unit, which has some general limitations – see thesection "Camera unit limitations".
NOTE
The function uses the vehicle's radar unit, which has some general limitations – see thesection "Radar unit limitations".

Ignition modes
The vehicle's ignition can be put in various modes (levels) to make different functions availa-ble.
To enable the use of a limited number of func- tions when the engine is not running, the ignition can be put in one of three different levels: 0, I
and II. These levels are referred to as "ignition
modes" in the Owner's Manual. The following table shows which functions are available in each ignition mode:
ModeFunctions
0 •The odometer, clock and tem- perature gauge are illuminated A
.
• The power seats
* can be
adjusted.
• The power windows can be used.
• The center display is activatedand can be used A
.
• The 12 V outlet in the cargo com- partment
* can be used.
• The infotainment system can be used A
.
In this ignition mode, the functions are available for a limited time and then switch off automatically.
I •The panoramic roof, power win-dows, 12 V outlet in passengercompartment, Bluetooth, naviga-tion, phone, blower and wind-shield wipers can be used.
• The power seats can be adjusted.
• The 12 V outlet in the cargo com-partment can be used.
Electrical current will be takenfrom the battery in this ignitionmode.ModeFunctions
II •The headlights illuminate.
• Warning/indicator lights illumi- nate for 5 seconds.
• A number of other systems areactivated. However, seat and rearwindow heating can only be acti-vated when the engine is running.
This ignition mode uses a lot ofcurrent from the battery andshould be avoided whenever pos-sible!

Battery drain The electrical functions in the vehicle drain the battery to varying degrees. Avoid using ignitionmode II when the engine is switched off. Use
ignition mode I instead, as this uses less electri-
cal current.
Note that certain accessories may also drain power from the electrical system. Do not usefunctions that use a lot of electrical current whenthe engine is turned off. Examples of such func-tions are:
• blower
• headlights
• windshield wipers
• audio system (especially at high volume).
If the starter battery voltage is low, a message isshown in the driver display. The vehicle's energy-saving function will then turn off or reduce certainfunctions, such as the blower and/or the audio system.
–Charge the battery by starting the engine and let it run for at least 15 minutes (drivingcharges the battery faster than letting theengine idle).

Jump starting using another battery
If the start battery is discharged, current from another battery can be used to start the vehicle.
Jumper cable connecting points.
To avoid short circuits or other damage, the fol- lowing steps are recommended when jump star-ting the battery using another battery: 1. Put the ignition in mode 0.
2. Make sure the auxiliary battery (the battery used to jump start the discharged battery) has a voltage of 12 volts.
3. If the auxiliary battery is in another vehicle, turn off that vehicle's engine and make surethat the vehicles are not touching each other. 4. Clamp the red jumper cable onto the auxiliary
battery's positive (+) terminal (1).
CAUTION
Connect the jump cable carefully to prevent short circuits with other components in theengine compartment.
5. Fold back the cover over your vehicle's posi-tive (+) jump start terminal (2).
6. Clamp the other end of the red jumper cable to your vehicle's positive (+) jump start termi- nal (2).
7. Clamp the black jumper cable onto the auxili- ary battery's negative (-) terminal (3).
8. Clamp the other end of the black jumper cable to your vehicle's negative (-) groundpoint (4).
9. Make sure the jumper cables are securely attached to help prevent sparks while jumpstarting.
10. Start the engine of the assisting vehicle and let it run for a few minutes at a higher idlingspeed than normal, about 1500 rpm.

Emission inspection readiness
How do states use OBD II for emission
inspections?
Many states connect a computer directly to a vehicle's OBD II system. The inspector can thenread "faults." In some states, this type of inspec-tion has replaced the tailpipe emission test.
How can my vehicle fail OBD II emission
inspection?
Your vehicle can fail OBD II emission inspection for any of the following reasons:
• If your Check Engine (MIL) light is lit, yourvehicle may fail inspection.
• If your vehicle's Check Engine light was lit,but went out without any action on your part,OBD II will still have a recorded fault. Yourvehicle may pass or fail, depending on theinspection practices in your area.
• If you had recent service that required dis-connecting the battery, OBD II diagnosticinformation may be incomplete and "notready" for inspection. A vehicle that is notready may fail inspection.
How can I prepare for my next OBD II
emission inspection?
• If your Check Engine (MIL) light is lit - or was lit but went out without service, have your vehicle diagnosed and, if necessary, servicedby a qualified Volvo technician.
• If you recently had service for a lit CheckEngine light, or if you had service thatrequired disconnecting the battery, a periodof driving is necessary to bring the OBD IIsystem to "ready" for inspection. Two half-hour trips of mixed stop-and-go/highwaydriving are typically needed to allow OBD II toreach readiness. Your Volvo retailer can pro-vide you with more information on planning atrip.
• Maintain your vehicle in accordance with yourvehicle's maintenance schedule.
Owner maintenancePeriodic maintenance requirements and intervalsare described in your vehicle's Warranty andService Records Information booklet. The following points can be carried out between the normally scheduled maintenance services.
Each time the car is refueled:
•Check the engine oil level.
• Clean the windshield, windshield wipers, headlights, and taillights.
Monthly:
• Check cold tire pressure in all tires. Inspect the tires for wear.
• Check that engine coolant and other fluidlevels are between the indicated "min" and"max" markings.
• Clean interior glass surfaces with a glasscleaner and soft paper towels.
• Wipe driver information displays with a softcloth.
• Visually inspect battery terminals for corro-sion. Corrosion may indicate a loose terminalconnector, or a battery near the end of itsuseful service life. Consult your Volvo retailerfor additional information.
As needed:
Wash the car, including the undercarriage, to reduce wear that can be caused by a buildup ofdirt, and corrosion that can be caused by salt res-idues. Clean leaves and twigs from air intake vents at the base of the windshield, and from other placeswhere they may collect.

Lift the rubber strip by pressing it inward into the engine compartment.
Remove the plastic cover by folding out the catch and lifting the cover upward.
Unscrew the expansion tank cap and fill coolant as needed. The level should be between the MIN and MAX marks on the
expansion tank.
CAUTION
• Mix the coolant with water of acceptable quality. If you are unsure of the quality ofthe water, use a Volvo-recommendedpremixed coolant.
• Make sure the coolant mixture is 50%water and 50% coolant.
• Only use coolants with corrosion protec-tion recommended by Volvo.
• To help ensure sufficient corrosion pro-tection in the system, only use new cool-ant when replacing larger components inthe cooling system.
• Never run the engine unless the coolingsystem is properly filled. An improperlyfilled cooling system could lead to hightemperatures and cracks in the cylinderheads.
• High levels of chlorine, chlorides andother salts may cause corrosion in thecooling system.

Replacing bulbs
The bulbs in the halogen headlights can be changed without the help of a workshop. Halogen headlights are not available on all mod- els and markets. Contact a Volvo retailer formore information. LED 13
bulbs must be replaced by a workshop.
An authorized Volvo workshop is recommended.
NOTE
For information on lights not mentioned in this article, contact a Volvo dealer or a certi-fied Volvo service technician.
The headlight bulbs can be replaced without the assistance of a workshop, but before a bulb canbe replaced, the plastic cover over the headlightneeds to be removed. The low beam lights will be accessible when the headlight's round rubber cover has beenremoved. The bulbs of the turn signals, high beam and day- time running lights/parking lights are accessibleonce the rectangular headlight cover has beenremoved.

* Option/accessory.
592 If you are experiencing problems with any lights other than light bulbs, contact a workshop
14
. If
there is a problem with an LED 13
light, the entire
lamp unit will normally need to be replaced.
WARNING
The vehicle electrical system must be in igni- tion mode 0 when bulbs are replaced.
CAUTION
Never touch the bulb glass with your bare fin- gers. Grease and oils from your fingers vapor-ize in the heat and will leave a deposit on thereflector, which may damage it.
NOTE
If the error message persists after the defec- tive bulb has been replaced, we recommend avisit to an authorized Volvo workshop.
NOTE
Exterior lighting such as headlights and tail- lights may develop temporary condensationon the inside of the lens. This is normal. Allexterior lighting is designed to resist this.Condensation is normally vented out of thelamp housing once the light has been lit forsome period of time.
NOTE
Bulbs for active curve lighting * contain traces
of mercury and should therefore always be submitted to a certified Volvo service techni-cian.
