system that illuminates a low tire pressure telltale (
) when one or more of your tires is signifi-
cantly under-inflated. Accordingly, when the low tire pressure telltale illuminates, you should stopand check your tires as soon as possible, andinflate them to the proper pressure. Driving on a significantly under-inflated tire cau- ses the tire to overheat and can lead to tire fail-ure. Under-inflation also reduces fuel efficiencyand tire tread life, and may affect the vehicle'shandling and stopping ability. Please note that atire pressure monitoring system is not a substi-tute for proper tire maintenance, and it is the driv-er's responsibility to maintain correct tire pres-sure, even if under-inflation has not reached thelevel to trigger illumination of the system's lowtire pressure telltale. Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when thesystem is not operating properly. The monitoringsystem's malfunction indicator is combined withthe low tire pressure telltale. When the system detects a malfunction, the tell- tale will flash for approximately one minute andthen remain continuously illuminated. Thissequence will continue upon subsequent vehiclestart-ups as long as the malfunction exists. Whenthe malfunction indicator is illuminated, the sys-tem may not be able to detect or signal low tirepressure as intended. System malfunctions may occur for a variety ofreasons, including the installation of replacementor alternate tires or wheels on the vehicle thatprevent the tire pressure monitoring system fromfunctioning 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 pressure monitoring - overview (p. 316)
• Calibrating Tire Monitor (p. 318)
Calibrating Tire Monitor In order for Tire Monitor to work correctly, tire pressure reference values must be set (the sys-tem must be calibrated). This must be doneeach time wheels or tire pressures are 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).
3. Start the engine but keep the vehicle at a standstill.
4. Press the MY CAR button on the center
console control panel and press OK/MENU.
5. Select
Tire monitor.
6. Select
Start calibration and press OK/
MENU .
7. Press OK/MENU again after all of the tires
have been checked and reinflated. 8. Drive away.
> The calibration process will begin whenthe vehicle reaches a speed of approxi- mately 22 mph (35 km/h). Calibration willbe interrupted if the engine is switchedoff but will resume automatically in thebackground when the vehicle is drivenagain. The system will not give any confir-mation when calibration is finished.
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 Pressure Monitoring System (TPMS) – changing wheels
Please keep the following in mind when chang- ing or replacing the factory installed TPMSwheels/tires on the vehicle:
• Not all aftermarket wheels are equipped withTPMS sensors in the valves.
• If the vehicle is equipped with a temporaryspare tire, this tire does not have a TPMSsensor.
• If wheels without TPMS sensors are moun-ted on the vehicle, a text message will dis-played in the instrument panel each time thevehicle is driven above 20 mph (30 km/h) for10 minutes or more.
• Once TPMS sensors are properly installed,the warning message should not reappear. Ifthe message is still displayed, drive the vehi-cle for several minutes at a speed of 20 mph(30 km/h) or faster to erase the message.
• Volvo recommends that TPMS sensors befitted on all wheels used on the vehicle,including winter tires. Volvo does not recom-mend moving sensors back and forthbetween sets of wheels.
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.

Message
Oil level
The oil level can be checked when the engine is not running by scrolling to the oil level sensorusing the thumb wheel on the left steering wheellever.
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. 384).
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. 82).
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 value available will
be displayed. This does not indicate a
problem with the oil level sensor.
