, press START/STOP
ENGINE for approximately 2 seconds to
activate ignition mode II.
2. The remote key must remain in the igni- tion slot 23
for the entire time that the vehi-

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 tireswith each other it is possible to determine ifone or more tires are under inflated. When low inflation pressure is detected or if the system is not functioning properly, TireMonitor will light up the tire pressure warning light (
) (also referred to as a telltale) in
the instrument panel and will display one of the following messages in the text window, for example:
Tire pressure low Check rear
right tire5 or Tire press. syst Service
required.
If two or more tires have low pressure or if the system cannot determine which tire has low pressure, a general text (
Tire pressure low
Check tires) will be displayed.
NOTE
If a malfunction occurs in the system, the tire pressure warning light will flash forapproximately 1 minute and then remain illuminated.
Tire press. syst Service
required will be displayed.
NOTE
The system indicates low tire pressure but does not replace normal tire maintenance.For information on correct tire pressure,please refer to the tire inflation pressuretable (see Tire inflation – pressure table(p. 300)), the tire inflation pressure placardlocated on the driver's side B-pillar (thestructural member at the side of the vehi-cle, at the rear of the driver's door open-ing) or consult your Volvo retailer.

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 pres-sures are changed.
Calibration1. Switch off the engine.
2. Inflate the tires to the desired pressure
(consult tire pressure placard located on the driver's side B-pillar (the structuralmember at the side of the vehicle) andput the ignition in mode II, see Ignition
modes (p. 79).
3. Press the MY CAR button on the center
console control panel and select

Maintenance – owner maintenance
Periodic 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.
Owner maintenance
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 asoft cloth.
• Visually inspect battery terminals for cor-rosion. Corrosion may indicate a looseterminal connector, or a battery near theend of its useful service life. Consult yourVolvo retailer for additional information.
As needed:Wash the car, including the undercarriage, to reduce wear that can be caused by a buildup of dirt, and corrosion that can be caused bysalt residues. Clean leaves and twigs from air intake vents at the base of the windshield, and from otherplaces where they may collect.

Onboard Diagnostic System
OBD 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 tempo-rary. OBD II will store a message about anyfault.
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 waslit, but went out without any action onyour part, OBD II will still have a recordedfault. Your vehicle may pass or fail,depending on the inspection practices inyour area. •
If you had recent service that requireddisconnecting the battery, OBD II diag-nostic information may be incompleteand "not ready" for inspection. A vehiclethat is not ready 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, haveyour 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 neededto allow 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.
