STARTING AND DRIVING
278nents, altering emission system components or location or removing components, and/orrepeated use of leaded fuel.
NOTE
Unleaded fuel is required for vehicles with three-way catalytic converters.
Heated oxygen sensorsThe heated oxygen sensors monitor the oxygen content of the exhaust gases. Readings are fedinto a control module that continuously monitorsengine functions and controls fuel injection. Theratio of fuel to air into the engine is continuouslyadjusted for efficient combustion to help reduceharmful emissions.

Economical driving
Better driving economy may be obtained by thinking ahead, avoiding rapid starts and stopsand adjusting the speed of your vehicle to imme-diate traffic conditions.
Economical driving conserves natural
resources
Observe the following rules: • Bring the engine to normal operating tem- perature as soon as possible by driving witha light foot on the accelerator pedal for thefirst few minutes of operation. A cold engineuses more fuel and is subject to increasedwear.
• Whenever possible, avoid using the vehiclefor driving short distances. This does notallow the engine to reach normal operatingtemperature.
• Drive carefully and avoid rapid accelerationand hard braking.
• Use the transmission's Drive (
D) position as
often as possible and avoid using kick-down.
• Using the transmission's Sport mode mayincrease fuel consumption somewhat. Use the transmission's Drive (
D) position as often
as possible. For additional information about Sport mode, see Transmission – Geartronic(p. 254).
• Do not exceed posted speed limits. •
Avoid carrying unnecessary items (extra load)in the vehicle.
• Maintain correct tire pressure. Check tirepressure regularly (when tires are cold).
• Remove snow tires when threat of snow orice has ended.
• Note that roof racks, ski racks, etc, increaseair resistance and also fuel consumption.
• At highway driving speeds, fuel consumptionwill be lower with the air conditioning on andthe windows closed than with the air condi-tioning off and the windows open.
• Using the onboard trip computer's fuel con-sumption modes can help you learn how todrive more economically.
Other factors that decrease gas mileage are:
• Dirty air cleaner
• Dirty engine oil and clogged oil filter
• Dragging brakes
• Incorrect front end alignment
Some of the above mentioned items and othersare checked at the standard maintenance inter-vals.

MAINTENANCE AND SERVICING

* Option/accessory, for more information, see Introduction.325
Onboard Diagnostic System OBD II is part of your vehicle's computerized engine management system. It stores diagnosticinformation about your vehicle's emission con-trols. It can light the Check Engine light (MIL) if itdetects an emission control "fault." A "fault" is acomponent or system that is not performingwithin an expected range. A fault may be perma-nent or temporary. OBD II will store a messageabout any fault.
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 diagnostic information 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 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.
Booking service and repairs
Connected Service Booking (CSB) makes set- ting up a time for service, maintenance and/orrepairs directly from the vehicle quick and con-venient.
Prerequisites
• The owner (primary driver) must have a valid Volvo ID. See Volvo ID (p. 22) for additionalinformation.
• The vehicle must be connected to the Inter- net using a paired Bluetooth ®
cell phone.
See your Sensus Infotainment supplement for information on pairing a cell phone. On models equipped with Volvo On Call (VOC) *,
you can connect to the Internet using your separate VOC data plan. Refer to your sepa-rate Volvo On Call manual.
• By default, the retailer where you purchasedyour vehicle will be your preferred (primary)retailer/Volvo authorized workshop who willperform service and repairs on your vehicle.To change the preferred retailer, go to DealerLocator at volvocars.com and select aretailer, click on Service Scheduler and bookan appointment at the new preferred retailer.
• In order to be guided through the on-screen steps, the menu alternative
