Driver intervention
Backing up
City Safety is temporarily deactivated when the vehicle is backing up.
Low speed
City Safety is not activated at very low speeds under 4 km/h (3 mph). The system will there-fore not intervene in situations in which yourvehicle is approaching another vehicle veryslowly, such as when parking.
Active driver
Action by the driver always has priority. City Safety will therefore not react or will react at alater stage with a warning or intervention insituations in which the driver is clearly steeringand operating the accelerator pedal, even if acollision is unavoidable. An active and aware driving style may there- fore delay collision warnings and interventionin order to minimize unnecessary warnings.
Other limitations
WARNING
The driver support system only issues a warning for obstacles detected by its radarsensor – thus, a warning may come after adelay or not at all. Never wait for a warning or assistance. Apply the brakes when necessary.
WARNING
Warnings and brake interventions can be triggered late or not at all if the traf-fic situation or external influences pre-vent the camera and radar unit fromproperly detecting pedestrians,cyclists, large animals or vehiclesahead of the vehicle.
To be able to detect vehicles at night,its front and rear lights must work andilluminate clearly.
The camera and radar unit have a lim-ited range for pedestrians and cyclists– the system can provide effectivewarnings and brake interventions if therelative speed is lower than 50 km/h(30 mph). For stationary or slow-mov-ing vehicles, warnings and brake inter-ventions are effective at vehicle speedsof up to 70 km/h (43 mph). Speedreduction for large animals is less than15 km/h (9 mph) and can be achievedat vehicle speeds over 70 km/h(43 mph). At lower speeds, the warn-ing and brake intervention for large ani-mals is less effective.
Warnings for stationary or slow-mov-ing vehicles and large animals can bedisengaged due to darkness or poorvisibility.
Warnings and brake interventions for pedestrians and cyclists are disen-gaged at vehicle speeds over 80 km/h(50 mph).
Do not place, affix or mount anythingon the inside or outside of the wind-shield, or in front of or around the cam-era and radar unit – this could disruptcamera-based functions.
Objects, snow, ice or dirt in the area ofthe camera sensor can reduce thefunction, disengage it completely orgive an improper function response.

Park Assist front, rear and sides *
Park Assist behaves differently depending on which part of the vehicle is approaching anobstacle.
Front camera
The warning signal has a continuous tone when the obstacle is less than approx. 30 cm (1 ft) from thevehicle.
The Park Assist system's front sensors are automatically activated when the engine isstarted. They are active at speedsbelow 10 km/h (6 mph). The distance monitored extends approx. 80 cm (2.5 ft) in front of the vehicle.
NOTE
The Park Assist system is deactivated when the parking brake is used or when P
is selected on vehicles with automatictransmission.
CAUTION
When installing auxiliary lights: Make sure these do not obscure the sensors – theauxiliary lights could be perceived as anobstacle.
Back
The warning signal has a continuous tone when the obstacle is less than approx. 30 cm (1 ft) from thevehicle.
The rear sensors will be activated if the vehicle begins rolling backward or if reverse gear isengaged. The distance monitored extends approx. 1.5 meters (5 ft) behind the vehicle.
Side sensors
The warning signal will begin pulsating rapidly when the obstacle is less than approx. 25 cm (0.8 ft) fromthe vehicle.
Park Assist's side sensors are automatically activated when the engine is started. They areactive at speeds below 10 km/h (6 mph). The distance monitored is approx. 25 cm (0.8 ft) out from the sides. The detection area of the side sensors increa- ses significantly, however, when the steering angle of the front wheel increases and depending on the position of the steeringwheel, obstacles up to approx. 90 cm (3 ft)

Ignition modes The vehicle's ignition can be put in various modes (levels) to make different functionsavailable.
To enable the use of a limited number of func- tions when the engine is not running, the igni-tion can be put in one of three different levels:0, I and II. These levels are referred to as "igni-
tion modes" in the Owner's Manual. The following table shows which functions are available in each ignition mode:

WARNING
If the warning symbols for both brake fault and ABS fault are lit simultaneously, theremay be a fault in the brake system.
If the brake fluid reservoir level is nor- mal when this occurs, drive carefully tothe nearest workshop to have thebrake system checked - an authorizedVolvo workshop is recommended.
If the brake fluid has fallen below theMIN
level in the brake fluid reservoir,
the vehicle should not be driven untilthe brake fluid has been filled. The rea-son for the brake fluid loss must bechecked.

Brake Assist System The brake enhancing system, (BAS 3
), helps
increase braking force and can thereby reduce braking distance.
The system monitors the driver's braking hab- its and increases braking force when neces-sary. Braking force can be increased up to thepoint at which the ABS intervenes. The func-tion is deactivated when pressure on the brakepedal is decreased.
NOTE
When BAS is activated, the brake pedal will go down slightly more than usual.Press (hold) down the brake pedal as longas necessary. When the brake pedal is released, all brak- ing ceases.
Related information
Brakes (p. 383)
Braking on wet roads
Prolonged driving in heavy rain without brak- ing may cause braking effect to be slightlydelayed the first time the brakes are applied.
This may also occur after washing the vehicle. It will then be necessary to apply greater pres-sure to the brake pedal. You should thereforemaintain a greater distance to the vehicleahead. Firmly apply the brakes after washing the vehicle or driving on wet roads. This helpswarm up the brake discs, enabling them to drymore quickly and protecting them against cor-rosion. Consider the current traffic situationwhen braking.

Winter driving
It is important to check the vehicle before driving in cold/snowy conditions to makesure it can be driven safely.
Before the cold season arrives: Make sure the engine coolant contains 50% antifreeze. This mixture helps pro-tect the engine from frost erosion down toapprox. –35 °C (–31 °F). Do not mix dif-ferent types of antifreeze as this couldpose a health risk.
Keep the fuel tank well filled to preventcondensation from forming.
Check the viscosity of the engine oil. Oilwith low viscosity (thinner oil) improvescold-weather starting and reduces fuelconsumption when driving with a coldengine.
CAUTION
Low-viscosity oil should not be used with hard driving or in hot weather.
Check the condition and charge level of the start battery. Cold weather placesgreater demands on the start battery andreduces its capacity.
Use washer fluid containing antifreeze tohelp prevent ice from forming in thewasher fluid reservoir.

Emission controls
Three-way catalytic converter
Keep your engine properly tuned. Certain engine malfunctions, particularly involvingthe electrical, fuel or distributor ignitionsystems, may cause unusually high three-way catalytic converter temperatures. Donot continue to operate your vehicle if youdetect engine misfire, noticeable loss ofpower or other unusual operating condi-tions, such as engine overheating or back-firing. A properly tuned engine will helpavoid malfunctions that could damage thethree-way catalytic converter.
Do not park your vehicle over combustiblematerials, such as grass or leaves, whichcan come into contact with the hotexhaust system and cause such materialsto ignite under certain wind and weatherconditions.
Excessive starter cranking (in excess ofone minute), or an intermittently firing orflooded engine can cause three-way cata-lytic converter or exhaust system over-heating.
Remember that tampering or unauthor-ized modifications to the engine, theEngine Control Module, or the vehicle maybe illegal and can cause three-way cata-lytic converter or exhaust system over-heating. This includes: altering fuel injec- tion settings or components, alteringemission system components or locationor removing components, and/or repeateduse of leaded fuel.
NOTE
Unleaded fuel is required for vehicles with three-way catalytic converters.
Heated oxygen sensorsThe heated oxygen sensors monitor the oxy- gen content of the exhaust gases. Readings are fed into a control module that continuouslymonitors engine functions and controls fuelinjection. The ratio of fuel to air into the engineis continuously adjusted for efficient combus-tion to help reduce harmful emissions.

Battery drain
The electrical functions in the vehicle drain the battery to varying degrees. Avoid usingignition mode II when the engine is switched
off. Use ignition mode I instead, as this uses
less electrical current.
Note that certain accessories may also drain power from the electrical system. Do not usefunctions that use a lot of electrical currentwhen the engine is turned off. Examples ofsuch functions are: blower
headlights
windshield wipers
audio system (especially at high volume).
If the starter battery voltage is low, a message is shown in the driver display. The vehicle'senergy-saving function will then turn off orreduce certain functions, such as the blowerand/or the audio system.
–Charge the battery by starting the engine and let it run for at least 15 minutes (driv-ing charges the battery faster than lettingthe engine idle).

Periodic maintenance helps minimize emissions
NOTE
Refer to your Service and Warranty Booklet for a comprehensive serviceand maintenance schedule up to240,000 km (150,000 miles). Thisprogram contains inspections and ser-vices necessary for the proper functionof your vehicle and includes compo-nents that affect vehicle emissions.
The Warranty and Service RecordsInformation booklet also containsdetailed information concerning thewarranties that apply to your vehicle.
On-board Diagnostic SystemOBD II is part of your vehicle's computerized engine management system. It stores diag-nostic information about your vehicle's emis-sion controls. It can light the Check Enginelight (MIL) if it detects an emission control"fault." A "fault" is a component or systemthat is not performing within an expectedrange. A fault may be permanent or temporary.OBD II will store a message about any fault.
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 canthen read "faults." In some states, this type ofinspection has replaced the tailpipe emissiontest.
How can my vehicle fail OBD II emission
inspection?
Your vehicle can fail OBD II emission inspec- tion for any of the following reasons: If your Check Engine (MIL) light is lit, your vehicle may fail inspection.
If your vehicle's Check Engine light was lit,but went out without any action on yourpart, OBD II will still have a recorded fault.Your vehicle may pass or fail, dependingon the inspection 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,serviced by a qualified Volvo technician.
If you recently had service for a lit CheckEngine light, or if you had service thatrequired disconnecting the battery, aperiod of driving is necessary to bring theOBD II system to "ready" for inspection.Two half-hour trips of mixed stop-and-go/highway driving are typically needed toallow OBD II to reach readiness. YourVolvo retailer can provide you with moreinformation on planning a trip.
Maintain your vehicle in accordance withyour vehicle's maintenance schedule.
Owner maintenancePeriodic maintenance requirements and inter-vals are described in your vehicle's Warrantyand Service Records Information booklet. The following points can be carried out between the normally scheduled maintenanceservices.
Each time the vehicle is refueled:
Check the engine oil level.
Clean the windshield, windshield wipers, headlights, and taillights.
