City Safety – introduction
City Safety™5
is a support system designed
to help the driver avoid low speed collisions when driving in slow-moving, stop-and-gotraffic. City Safety™ is not active if your vehicle’s speed is below approximately 2 mph(4 km/h). This means that City Safety™ willnot react if your vehicle approaches anothervehicle at very low speed, for example, whenparking. The function is active at speeds up to approximately 30 mph (50 km/h) and assiststhe driver by applying the brakes automati-cally, thereby avoiding or helping to reducethe effects of a collision. City Safety™ is designed to intervene as late as possible to help avoid unnecessary activa-tion. City Safety™ triggers brief, forceful braking if a low-speed collision is imminent. However,the system will not intervene in situationswhere the driver actively steers the vehicle orapplies the brakes, even if a collision cannotbe avoided. This is done in order to alwaysgive the driver’s actions highest priority. City Safety™ activates in situations where the driver has not applied the brakes in time, which means that the system cannot help thedriver in all situations. City Safety™ should not be used to alter the way in which the driver operates the vehicle.The driver should never rely solely on thissystem to safely stop the vehicle. Normally, the occupants of the vehicle will not be aware of City Safety™ except whenthe system intervenes when a low-speed col-lision is imminent. If the vehicle is also equipped with the optional Collision Warning with Full Auto-brake and Pedestrian Detection system, thetwo systems interact. For more informationabout the Collision Warning with Auto-brakesystem, see Collision warning – introduction(p. 209) .
WARNING
•
City Safety™ is a supplemental aid to the driver. It can never replace thedriver’s attention to traffic conditionsor his/her responsibility for operatingthe vehicle in a safe manner.
• City Safety™ does not function in alldriving situations or in all traffic,weather or road conditions.
WARNING
•
City Safety™ only reacts to vehicles traveling in the same direction as yourvehicle and does not react to smallvehicles or motorcycles or to people oranimals.
• City Safety™ is not activated whenyour vehicle is backing up.
• City Safety™ functions at speeds upto 30 mph (50 km/h). This system canhelp prevent a collision if the
differ-
ence in speed between your vehicle
and the vehicle ahead is less than9 mph (15 km/h). If the difference inspeed is greater, a collision cannot beavoided but the speed at which thecollision occurs can be reduced. Thedriver must apply the vehicle’s brakesfor full braking effect.
• City Safety™ will not intervene in apotential collision situation if the vehi-cle is being driven actively. The driveris always responsible for maintaining asafe distance to a vehicle or objectahead.

WARNING
• In certain situations, the system can- not provide warnings or warnings maybe delayed if traffic conditions or otherexternal factors make it impossible forthe radar sensor or camera to detect apedestrian, a cyclist or a vehicleahead.
• Warnings may not be provided if thedistance to the vehicle ahead is short,or if movements of the steering wheel/brake pedal are great, such as duringactive driving.
• The sensor system has a limited rangefor pedestrians/cyclists and provideswarnings and braking effect mosteffectively at speeds up to 30 mph(50 km/h). For stationary or slow-mov-ing vehicles, the system functions bestif your vehicle’s speed is belowapproximately 45 mph (70 km/h).
• Warnings for stationary or slow-mov-ing vehicles may not be provided indark conditions or in poor visibility.
The Pedestrian and Cyclist Detection with Full Auto Brake system uses the same radar sen-sors as Adaptive Cruise Control. For moreinformation on the radar sensor and its limita-tions, see Adaptive Cruise Control – limita-tions (p. 193).
NOTE
If warnings are given too frequently, the warning distance can be reduced (see Col-lision warning* – operation (p. 212)). Thiscauses the system to provide later warn-ings, which decreases the total number ofwarnings provided.
WARNING
•The system is not activated at speeds under approx. 2 mph (4 km/h). There-fore, it will not brake your vehicle if youapproach a vehicle ahead at very lowspeed, such as when parking.
• The driver's actions always have high-est priority and override the Pedestrianand Cyclist Detection with Full AutoBrake system. This means that thesystem will not intervene in situationswhere the driver is actively steering,braking or pressing the acceleratorpedal, even if a collision is imminent.
• When Auto-brake has prevented a col-lision with a stationary object, yourvehicle will remain at a standstill forapprox. 1.5 seconds. If your vehiclehas been braked for a moving vehicleahead, your vehicle's speed will bereduced to the same speed as thatvehicle's.

Faults in the systemIf the information symbol illuminates andPark assist syst Service required is shown
on the information display, this indicates that the system is not functioning properly andhas been disengaged. Consult a trained andqualified Volvo service technician.
CAUTION
In certain circumstances, the park assist system may give unexpected warning sig-nals that can be caused by external soundsources that use the same ultrasound fre-quencies as the system. This may includesuch things as the horns of other vehicles,wet tires on asphalt, pneumatic brakes,motorcycle exhaust pipes, etc. This doesnot indicate a fault in the system.

Rear Park Assist Camera (PAC) – introduction
The Park Assist Camera is designed to pro- vide the driver with a view of the area behindthe vehicle when backing up.
IntroductionPAC uses the display in the center console toshow the area behind the car while you arebacking up. PAC also shows guiding lines in the on- screen image to indicate the direction that thevehicle will take as it moves rearward, whichhelps simplify parallel parking, backing into atight space or when attaching a trailer to thevehicle. The images of vehicles in this section are generic and may not depict your specificmodel.
NOTE
A trailer hitch whose wiring is integrated with the vehicle's electrical system will beincluded in the measurement of the availa-ble space behind the vehicle.
WARNING
• PAC is designed to be a supplemen- tary aid when parking the vehicle. It isnot, however, intended to replace thedriver’s attention and judgment.
• The camera has blind spots where itcannot detect objects or peoplebehind the vehicle.
• Pay particular attention to people oranimals that are close to the vehicle.
• Objects seen on the screen may becloser than they appear to be.

WARNING
•Always remove the remote key from the ignition slot when leaving the vehi-cle and ensure that the ignition inmode
0 (see Ignition modes (p. 79) for
information about the ignition modes).
• On vehicles with the optional keylessdrive, never remove the remote keyfrom the vehicle while it is being drivenor towed.
• Always place the gear selector in Parkand apply the parking brake beforeleaving the vehicle. Never leave thevehicle unattended with the enginerunning.
• Always open garage doors fully beforestarting the engine inside a garage toensure adequate ventilation. Theexhaust gases contain carbon monox-ide, which is invisible and odorless butvery poisonous.
NOTE
•
After a cold start, idle speed may be noticeably higher than normal for ashort period. This is done to help bringcomponents in the emission controlsystem to their normal operating tem-perature as quickly as possible, whichenables them to control emissions andhelp reduce the vehicle's impact on the environment 3
.
CAUTION
• When starting in cold weather, the automatic transmission may shift up atslightly higher engine speeds than nor-mal until the automatic transmissionfluid reaches normal operating tem-perature.
• Do not race a cold engine immediatelyafter starting. Oil flow may not reachsome lubrication points fast enough toprevent engine damage.
• The engine should be idling when youmove the gear selector. Never acceler-ate until after you feel the transmissionengage. Accelerating immediately afterselecting a gear will cause harshengagement and premature transmis-sion wear.
• Selecting
P or N when idling at a
standstill for prolonged periods of timewill help prevent overheating of theautomatic transmission fluid.

Brakes – general
The brake system is a hydraulic system con- sisting of two separate brake circuits. If aproblem should occur in one of these circuits,it is still possible to stop the vehicle with theother brake circuit. If the brake pedal must be depressed farther than normal and requires greater foot pres-sure, the stopping distance will be longer. A warning light in the instrument panel will light up to warn the driver that a fault hasoccurred. If this light comes on while driving or braking, stop immediately and check the brake fluidlevel in the reservoir.
NOTE
Press the brake pedal hard and maintain pressure on the pedal – do not pump thebrakes.
WARNING
If the fluid level is below the
MIN mark in
the reservoir or if a brake system message is shown in the information display: DO
NOT DRIVE . Have the vehicle towed to a
trained and qualified Volvo service techni-cian and have the brake system inspected.
Brake pad inspectionOn vehicles equipped with a jack*, the condi- tion of the brake pads can be checked byraising the vehicle (see Changing a wheel –removing wheel (p. 291) for informationabout using the jack and removing a wheel)and performing a visual inspection of thebrake pads.
WARNING
• If the vehicle has been driven immedi- ately prior to a brake pad inspection,the wheel hub, brake components,etc., will be very hot. Allow time forthese components to cool before car-rying out the inspection.
• Apply the parking brake and put thegear selector in the Park (
P) position.
• Block the wheels standing on theground, use rigid wooden blocks orlarge stones.
