To start the engine.
1. A remote key must be in the passenger com-
partment. On models with the standard Passive Start, the key has to be in the frontsection of the passenger compartment. If thevehicle is equipped the optional PassiveEntry system (keyless locking/unlocking) thekey can be anywhere in the vehicle.
2. Press firmly on the brake pedal 2
.
3. Turn the start knob toward START and
release it to start the engine.
> The starter motor will crank until the engine starts or its overheating protection is triggered.
WARNING
• Never use more than one floor mat at a time on the driver's floor. Before driving,remove the original mat from the driver'sseat floor before using any other type offloor mat. Any mat used in this positionshould be securely and properly anchoredin the attaching pins. An extra mat on thedriver's floor can cause the acceleratorand/or brake pedal to catch. Check thatthe movement of these pedals is notimpeded.
• Volvo's floor mats are specially manufac-tured for your car. They must be firmlysecured in the clips on the floor so thatthey cannot slide and become trappedunder the pedals on the driver's side.
During normal starts, the electric motor is priori-tized and the gasoline engine will not start. Thismeans that when the start knob has been turned toward START and released, the electric motor is
activated ("started") and the vehicle is ready to be driven. The warning and information symbolsin the instrument panel will go out and thechosen theme will be displayed to indicate thatthe electric motor has been activated. However, in certain situations, such as in coldweather or if the hybrid battery is not sufficientlycharged, the gasoline engine will start instead. The vehicle should not be started if the charging cable is connected.
However, if the
cable cannot be disconnected or if the vehicleincorrectly detects a cable that is not connected,the vehicle can be started using an override pro-cedure:
1. Press the brake pedal and turn the start
knob to START.
2.
Remove charge cable to start will appear
in the instrument panel.
3. Turn the start knob to START again.
4.
Charge cable removed? Press start button 7s to start will be displayed. Turn
the start knob to START again and hold it for
7 seconds to start the vehicle.
NOTE
The vehicle cannot be started if the hybrid battery is discharged.
2 If the vehicle is moving, it is only necessary to turn the start knob toward START to start the engine.

Back-up reader in the tunnel console
If Vehicle key not found is displayed in the
instrument panel, place the remote key in the back-up reader in the tunnel console (see theillustration) and try again to start the engine.
NOTE
When the remote key is in the back-up reader, be sure there are no other metallicobjects (e.g., other keys, coins, cell phones) inthe cup holder. This could affect the back-upreader's function.
If Vehicle start System check, wait is dis-
played in the instrument panel when you try to start the vehicle, wait until the message is nolonger displayed and try to start again.
CAUTION
If the engine does not start after the third try, wait for approximately 3 minutes before tryingto start it again to give the battery time torecover its starting capacity.
WARNING
• Always remove the remote key from the passenger compartment when leaving thevehicle and ensure that the ignition in mode
0.
• On vehicles with the optional Passive Entry, never remove the remote key fromthe vehicle while it is being driven ortowed.
• Always place the gear selector in Parkand apply the parking brake before leav-ing the vehicle. Never leave the vehicleunattended with the engine running.
• Always open garage doors fully beforestarting the engine inside a garage toensure adequate ventilation. The exhaustgases contain carbon monoxide, which isinvisible and odorless but very poisonous.
NOTE
After a cold start, idle speed may be noticea- bly higher than normal for a short period. Thisis done to help bring components in theemission control system to their normal oper-ating temperature as quickly as possible,which enables them to control emissions andhelp reduce the vehicle's impact on the envi-ronment.
CAUTION
•
When starting in cold weather, the auto- matic transmission may shift up at slightlyhigher engine speeds than normal untilthe automatic transmission fluid reachesnormal operating temperature.
• 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 accelerateuntil after you feel the transmissionengage. Accelerating immediately afterselecting a gear will cause harsh engage-ment and premature transmission wear.
• Selecting
P or N when idling at a stand-
still for prolonged periods of time will helpprevent overheating of the automatictransmission fluid.

Charging the hybrid battery In addition to the conventional fuel tank, Twin Engine Plug-in Hybrid vehicles are also equip-ped with a rechargeable lithium-ion hybrid bat-tery.
The hybrid battery is recharged using a charging cable located in a storage compartment underthe floor of the cargo area. See also the article"Charging cable."
WARNING
The hybrid electrical system in your vehicle uses high voltage electrical current. Any dam-age to this system or to the hybrid batterymay result in the danger of overheating, fire,or serious injury. If the vehicle is involved in acollision or is subjected to flooding, fires, etc.,have it inspected by a trained and qualifiedVolvo service technician. Prior to this inspec-tion, the vehicle should be parked outdoors ata safe distance from any building or poten-tially flammable materials.
The hybrid battery's charging time depends on the charging current used.
NOTE
The capacity of the hybrid battery diminishes somewhat with age and use, which couldresult in increased use of the gasoline engineand consequently, slightly higher fuel con-sumption.
Charging is indicated in three ways: • Charge module (the unit that is plugged into the wall socket): The blue indicator light onthe cable's charge module will flash red sev-eral times when the unit is plugged into awall socket while a safety check is being per-formed and will then glow steadily blue toindicate that the charger is ready to use.
• A green indicator light in the vehicle's charg-ing socket will flash green while the batteryis charging and will glow steadily green whenthe hybrid battery is fully charged. The blueindicator light in the charge module will alsoflash while charging is underway and willglow steadily blue when charging is comple-ted.
• A gauge in the instrument panel will alsoindicate the battery's charge level.
The hybrid battery charging process also chargesthe vehicle's start battery. If the hybrid battery's temperature is below – 13 ºF (–10 ºC) or above +104 ºF (+40 ºC), some
of the vehicle's functions may be reduced or not

WHEELS AND TIRES

Calibrating the Tire Pressure Monitoring System (TPMS)In order for the Tire Pressure Monitoring System to work properly, tire pressure reference valuesmust be set correctly. This must be done eachtime wheels are changed or tire pressures aremodified.
Calibrating TPMSTo calibrate the system:
1. Switch off the engine.
2. Re-inflate the tire(s) to the correct pressure. Consult the tire pressure decal located on the driver's side B-pillar (the structural mem-ber at the side of the vehicle, at the rear ofthe driver's door opening) or the inflationpressure table in your printed owner's man-ual supplement.
3. Start the engine. 4. Open the
Car status app in the center dis-
play's App view.
5. Tap Status to access Tire Pressure
Monitoring System. 6. Tap the calibration button. 7.
Tap
OK after the tire pressure in all four tires
has been checked and adjusted.
8. Drive the vehicle. > The calibration process will be completedwhile driving and will be interrupted if the vehicle is parked and the engine isswitched off. Calibration continues auto-matically when driving resumes.
When enough data has been collected to detecta low tire pressure situation, the tires' color in thecenter display will change to green. The systemwill not give any text confirmation when calibra-tion is finished although it will state if calibrationfails. When driving with heavy loads or at sus-tained highway speeds, the tire pressure shouldbe adjusted to the recommended inflation pres-sures. After adjusting inflation pressure, repeat steps 1-8.
NOTE
Always remember to calibrate the Tire Pres- sure Monitoring System when the wheelshave been changed or the tire inflation pres-sure has been corrected according to the tirepressure decal or tire inflation pressure table. If correct reference values have not been set, the system cannot issue low tire pressurealerts correctly. The vehicle must be parked with the engine running to access the calibration button andto start the calibration process.
WARNING
The exhaust gases contain carbon monoxide, which is invisible and odorless but very poi-sonous. For this reason, always perform thecalibration procedure outdoors or in a work-shop with exhaust gas evacuation equipment.

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.
