Common camera and radar limitations
Obstructed camera
The area marked in the illustration must be cleaned regularly and kept free of decals, objects, solar film,etc.
The camera is located on the upper interior section of the windshield along with the radarsensor. Do not place, affix or mount anything on the inside or outside of the windshield, or in frontof or around the camera and radar sensor –this could disrupt camera and radar-basedfunctions. It could cause functions to bereduced, deactivated completely or to producean incorrect function response.
High temperatures
If the temperature in the passenger compart- ment is very high, the camera/radar sensorwill switch off temporarily forapprox. 15 minutes after the engine is startedto protect its electronic components. Whenthe temperature has cooled sufficiently, thecamera/radar sensor will automatically restart.
Damaged windshield
NOTE
Failure to take action could result in reduced performance for the driver supportsystems that use the camera and radarunit. It could cause functions to bereduced, deactivated completely or to pro-duce an incorrect function response.
To avoid the risk of malfunction of the driver support systems that use the radar sensor, thefollowing also apply:
 If there are cracks, scratches or stonechips on the windshield in front of any ofthe camera and radar sensor "windows"and this covers an area ofabout 0.5 × 3.0 mm (0.02 × 0.12 in.) ormore, contact a workshop to have the windshield replaced 126
.
 Volvo advises 
against repairing cracks,
scratches or stone chips in the area in front of the camera and radar sensor – the entire windshield should instead bereplaced.
 Before replacing the windshield, contact a workshop 126
 to verify that the right wind-
shield has been ordered and installed.
 The same type of windshield wipers or wipers approved by Volvo should be usedfor replacement.
 If the windshield is replaced, the cameraand radar sensor must be recalibrated by a workshop 126
 to help ensure proper func-
tioning of all of the vehicle's camera and radar-based systems.
Additional radar limitations
Vehicle speed
The radar sensor's ability to detect a vehicle ahead is significantly reduced if the speed ofthe vehicle ahead differs greatly from yourvehicle's speed.
126 An authorized Volvo workshop is recommended.  

STARTING AND DRIVING

Preparing for a long trip
It is important to have the vehicle's systems and equipment checked carefully before driv-ing long distances.
Check that
 the engine is running properly and that fuel consumption is normal
 there are no leaks (fuel, oil or other fluid)
 the brake pedal is functioning properly
 all lights work
 tire tread depth and air pressure are atcorrect levels. Change to snow tires whendriving in areas where there is a risk ofsnowy or icy roads
 the start battery is sufficiently charged
 the wiper blades are in good condition

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.
 Check the condition and charge level ofthe 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.
See separate section for engine oil recommen-dations.
Slippery driving conditionsTo help optimize traction and roadholding,Volvo recommends using snow tires on allwheels whenever there is a risk of snow or iceon the road.
NOTE
Certain countries require use of winter tires by law. Not all countries permit the use ofstudded tires.
Practice driving on slippery surfaces under controlled conditions to learn how the vehiclereacts.

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.
–To charge the battery, start 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 vehi-cle.
Jumper cable connecting points. Engine compart- ment appearance may vary depending on vehiclemodel and equipment level.
To avoid short circuits or other damage, the following steps are recommended when jumpstarting the battery using another battery: 
1. Put the ignition in mode 
0.
2. Make sure the auxiliary battery (the bat- tery used to jump start the discharged battery) has a voltage of 12 volts.   

MAINTENANCE AND SERVICE

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.
