start-ups as long as the malfunction exists. When the malfunction indicator is illuminated, the sys-tem may not be able to detect or signal low tirepressure as intended. TPMS malfunctions may occur for a variety of reasons, including the installation of replacementor alternate tires or wheels on the vehicle thatprevent the TPMS from functioning properly.Always check the TPMS malfunction telltale afterreplacing one or more tires or wheels on yourvehicle to ensure that the replacement or alter-nate tires and wheels allow the TPMS to con-tinue to function properly.
Messages in the instrument panelWhen the TPMS symbol illuminates, the following text messages may also be displayed:
•
Tire pressure low: the tire(s) affected will
also be specified.
•
Tire needs air now: the tire(s) affected will
also be specified.
•
Tire pressure system Service required.
If TPMS cannot determine which tire(s) have low inflation pressure, general messages may be dis-played, such as:
•
Tire pressure low Check tires
•Tire needs air now Check tires
TPMS sensors can be installed on the valve hole area, on the factory-installed wheels as well as onoptional ones. If a spare wheel or other wheel without a TPMS sensor is used, a fault message will appear in theinstrument panel after driving for a few minutes. After changing wheels, always check that the new wheels have TPMS sensors to avoid a sys-tem malfunction warning. TPMS does not replace the need for regular tire inspection and maintenance.
RecommendationsTPMS sensors should be mounted on all wheelsused with the vehicle, including winter wheels.
NOTE
• If you change to tires with a different dimension than the factory-installed ones,the TPMS system must be reconfiguredfor these tires. This must be done by atrained and qualified Volvo service techni-cian.
• If a tire is changed, or if the TPMS sensoris moved to another wheel, the rubbervalve and valve core should be replaced.
• When installing TPMS sensors, the vehi-cle must be parked for at least15 minutes with the ignition off. If thevehicle is driven within 15 minutes, aTPMS error message will be displayed.
WARNING
Incorrect inflation pressure could lead to tire failure, resulting in a loss of control of thevehicle.

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, your vehicle 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 yourvehicle diagnosed and, if necessary, servicedby a qualified Volvo technician.
• If you recently had service for a lit CheckEngine light, or if you had service that required 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 intervals are 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.

Wi-Fi connection to a workshop The time a vehicle is in a workshop for service or repairs can be reduced by transmitting trouble-shooting information as soon as the car reachesthe workshop. This is done most conveniently by selecting
Automatically connect when I arrive in the
center display's Settings menu.
Each time the vehicle slows down to a sufficiently low speed, it begins searching for a Wi-Fi net-work. If an authorized Volvo network (at a retaileror workshop) is found, a message will be dis-played or a pop-up window will open in the cen-ter display (this applies to manual connections,see the section "Manually connecting to a work-shop" below).
Automatically connecting to a workshop
Without driver confirmationThis is the most convenient way to transmit trou- ble-shooting data. The driver does not need toconfirm that the vehicle will establish a connec-tion. If the vehicle stops at a workshop and the engine is switched off using the start knob, a messagewill appear above the status bar in the center dis-play. The vehicle will be automatically connectedwhen the driver's door is opened if the driver does not tap the
Cancel button in the message.
To help prevent the driver from being disturbed by unwanted requests to connect (e.g., if the vehicle is often parked near a workshop with anauthorized Volvo network), the vehicle will switchto manual connection if the driver cancels a con-nection request twice within 5 days.
With driver confirmationWith this alternative, the driver must confirm a connection. If the vehicle stops at a workshop and the engine is switched off using the start knob, a pop-upwindow will open in the center display. The vehi-cle will be automatically connected when the driv- er's door is opened if the driver taps
Connect in
the pop-up window. If the driver does nothing or taps the pop-up window's
Abort button, no
attempt will be made to establish a connection.
NOTE

Support battery Vehicles equipped with Start/Stop are equipped with two 12-volt batteries.
In addition to a heavy-duty start battery, models with Start/Stop also have a support battery thatprovides extra current during the Start/Stopfunction's start sequence.
The support battery is located in a box next to the spring strut in the engine compartment
The following table shows the specifications for the support battery:
Current (V)12
Cold start capacity (Cold Cranking Amperes -CCA) (A)170
Dimensions, L×W×H in. (mm)5.9×3.5×5.1
(150×90×130)
Capacity (Ah)10
• When replacing the start battery or support battery in a vehicle with Start/Stop, anAbsorbed Glass Mat (AGM) must be used.
• The greater the current consumption in thevehicle, the more the generator has to oper-ate and the battery is charged. This increasesfuel consumption.
• When the start battery's charge is below theminimum permitted level, the Start/Stopfunction will be disabled.
When the Start/Stop function is temporarily disa- bled due to high current consumption:
• The engine will auto-start, even if the brake pedal is depressed.
The support battery does not normally required more service than the start battery. If questionsarise, consult a Volvo retailer or trained and quali-fied Volvo service technician.
CAUTION
When connecting an external start battery or a battery charger, the Start/Stop function maybe temporarily disabled if the negative termi-nal on the vehicle's start battery is used toconnect an external start battery or a battery charger. Only the negative connection point
in the engine compartment may be used as a ground point.
NOTE
If the start battery is completely discharged and the vehicle has no normal electrical func-tions, and the engine is then started using anauxiliary battery or battery charger, theStart/Stop function will be activated. Theengine can then be auto-stopped but may notauto-start again due to an insufficient chargelevel in the start battery. To help ensure auto-start, the start battery should be charged first. At a temperature ofapprox. 60 °F (15 °C), the battery should becharged for at least 1 hour, preferably usingan external battery charger. At lower tempera-tures, the battery should be charged for3–4 hours. If a charger is not available, it is advisable to disable the Start/Stop function until the bat-tery is sufficiently recharged.
