Tire inflation placard
Tire inflationSee the tire inflation decal on the driver's door opening. This decal indicates the designation ofthe factory-mounted tires on your vehicle, as wellas load limits and inflation pressure.
NOTE
• The placards shown indicate inflation pressure for the tires installed on thevehicle at the factory only.
• A certain amount of air seepage from thetires occurs naturally and tire pressurefluctuates with seasonal changes in tem-perature. Always check tire pressure reg-ularly.
•Use a tire gauge to check the tire inflation pressure, including the spare, at least once amonth and before long trips. You are stronglyurged to buy a reliable tire pressure gauge,as automatic service station gauges may beinaccurate.
• Use the recommended cold inflation pres-sure for optimum tire performance and wear.
• Under-inflation or over-inflation may causeuneven treadwear patterns.
WARNING
•
Under-inflation is the most common cause of tire failure and may result insevere tire cracking, tread separation, or"blow-out," with unexpected loss of vehi-cle control and increased risk of injury.
• Under-inflated tires reduce the load car-rying capacity of your vehicle. When weather temperature changes occur, tire inflation pressures also change. A 10-degreetemperature drop causes a corresponding dropof 1 psi (7 kPa) in inflation pressure. Check yourtire pressures frequently and adjust them to theproper pressure, which can be found on the vehi-cle's tire information placard or certification label.

prevent the tire pressure monitoring system from functioning properly. Always check the system's malfunction telltale after replacing one or more tires or wheels onyour vehicle to ensure that the replacement oralternate tires and wheels allow the system tocontinue to function properly.
NOTE
The system indicates low tire pressure but does not replace normal tire maintenance. Forinformation on correct tire pressure, pleaserefer to the tire inflation decal on the driver'sdoor opening or consult your Volvo retailer.
WARNING
Incorrect inflation pressure could lead to tire failure, resulting in a loss of control of thevehicle.

Tire Monitor - introduction Tire Monitor uses the rotational speed of the tires in combination with signal analysis of theABS sensor signals to determine if they areproperly inflated.
When a tire is under-inflated, its diameter (and consequently also its rotational speed) changes.By comparing the individual tires with each otherit is possible to determine if one or more tires areunder inflated. When low inflation pressure is detected or if the system is not functioning properly, Tire Monitorwill light up the tire pressure warning light (
) (also referred to as a telltale) in the
instrument panel and will display one of several messages in the text window, for example:
Tire
pressure low Check tires. Adjust the inflation
pressure and recalibrate if necessary.
NOTE
If a malfunction occurs in the system, the tire pressure warning light will flash for approxi-mately 1 minute and then remain illuminated.
Tire press. syst Service required will be
displayed.

Calibrating Tire Monitor In order for Tire Monitor to work correctly, tire pressure reference values must be set. Thismust be done each time wheels or tire pressuresare changed.
Calibration1. Switch off the engine.
2. Inflate the tires to the desired pressure (con-sult tire pressure placard located on the driv- er's side B-pillar (the structural member atthe side of the vehicle) and put the ignition in mode II, see Ignition modes (p. 80).
3. Press the MY CAR button on the center
console control panel and select
Settings
Car settingsTire monitoring.
4. Press OK/MENU , select
Calibrate tire
pressure and press OK/MENU again after
all of the tires have been checked and rein- flated.
5. Drive away. > The calibration process will be completedwhile driving and will be interrupted if thevehicle is parked and the engine isswitched off. Calibration continues auto-matically when driving resumes. The sys-tem will not give any confirmation whencalibration is finished although it will stateif calibration fails. When driving with heavy loads or at sustainedhighway speeds, the tire pressure should beadjusted to the recommended inflation pressuresaccording to the tire inflation pressure placardlocated on the driver's side B-pillar (the structuralmember at the side of the vehicle, at the rear ofthe driver's door opening) or to the tire inflationpressure table in the owner's information. After adjusting inflation pressure, repeat steps 1-5 above.
NOTE
Always remember to calibrate Tire Monitor when the wheels have been changed or thetire pressure has been corrected according totire pressure placard or tire pressure table. Ifcorrect reference values have not been set,the system cannot issue low tire pressurealerts correctly.
Tire Monitor status information
The current status of the system and the tires is indicated by color-coded graphics.
This status can be displayed by pressing the MY
CAR button on the center console and going to
SettingsCar settingsTire monitoring.
The following color-coded graphics indicate:
• All green
: the system is operational and all
tire pressures are at or above the recom- mended levels.
• One yellow wheel
: the tire indicated is
under-inflated.
• All wheels yellow
: two or more tires are
under-inflated
• All wheels gray
: the system is currently
unavailable. It might be necessary to drive ata speed of at least 20 mph (30 km/h) forseveral minutes for the system to becomeoperational.

CAUTION
When inflating tires, press the pump's mouth- piece straight onto the valve to help avoidbending or otherwise damaging the valve.
CAUTION
•After inflating the tires, always reinstall the valve cap to help avoid damage to thevalve from dirt, gravel, etc.
• Use plastic valve caps only. Metal capscould corrode and become difficult toremove.
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 sensor'sseal, nut, and valve core should bereplaced.
• 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.

Tire Pressure Monitoring System (TPMS) – recalibrating
In certain cases, it may be necessary to recali- brate TPMS to conform to Volvo's recom-mended tire inflation pressures (see the tire infla-tion decal on the driver's door opening), forexample, if higher inflation pressure is necessarywhen transporting heavy loads.
Recalibrating TPMS (Canadian models
only) *
This is done in the vehicle's menu system. To recalibrate:
1. Switch off the engine.
2. Inflate the tires to the desired pressure and
put the ignition in mode I or II (see Ignition
modes (p. 80) for additional information).
3. Press the MY CAR key in the center console

331
CAUTION
•If Oil service required is displayed, the
oil level may be too high. Take the vehicle to an authorized Volvo workshop as soonas possible.
• If the oil level sensor indicates that thelevel is too low, using the correct oil, topup with the amount of oil indicated assoon as possible, see oil specifica-tions (p. 375).
WARNING
Do not allow oil to spill onto or come into con- tact with hot exhaust pipe surfaces.
Electronically checking the oil level
The oil level should be checked at regular inter- vals, particularly during the period up to the firstscheduled maintenance service. To check the oil level:1.
Activate ignition mode II, see Ignition modes
(p. 80).
2. Turn the thumb wheel on the left steering wheel lever until
Oil level is displayed.
> The oil level will be displayed.
NOTE
• The system cannot detect changes in the oil level immediately. The vehicle must bedriven approximately 20 miles (30 km) orhave been parked on level ground withthe engine off for 5 minutes before theoil level reading will be correct.
• If the necessary conditions are not metfor checking the oil level electronically(time interval after the engine wasswitched off, if the vehicle is parked on an incline, etc.),
No values available will
be displayed. This does not indicate a
problem with the oil level sensor.
Engine compartment – coolant
Normally, the coolant does not need to be changed. If the system must be drained, consulta trained and qualified Volvo service technician.
