Battery drain
The electrical functions in the vehicle drain the battery to varying degrees. Avoid usingignition mode II when the engine is switched
off. Use ignition mode I instead, as this uses
less electrical current.
Note that certain accessories may also drain power from the electrical system. Do not usefunctions that use a lot of electrical currentwhen the engine is turned off. Examples ofsuch functions are: blower
headlights
windshield wipers
audio system (especially at high volume).
If the starter battery voltage is low, a message is shown in the driver display. The vehicle'senergy-saving function will then turn off orreduce certain functions, such as the blowerand/or the audio system.
–Charge the battery by starting the engine and let it run for at least 15 minutes (driv-ing charges the battery faster than lettingthe engine idle).

Periodic maintenance helps minimize emissions
NOTE
Refer to your Service and Warranty Booklet for a comprehensive serviceand maintenance schedule up to240,000 km (150,000 miles). Thisprogram contains inspections and ser-vices necessary for the proper functionof your vehicle and includes compo-nents that affect vehicle emissions.
The Warranty and Service RecordsInformation booklet also containsdetailed information concerning thewarranties that apply to your vehicle.
On-board Diagnostic SystemOBD 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 temporary.OBD II will store a message about 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 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 was lit,but went out without any action on yourpart, OBD II will still have a recorded fault.Your vehicle may pass or fail, dependingon the inspection 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 your 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 needed toallow 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.
Owner maintenancePeriodic 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.
Each time the vehicle is refueled:
Check the engine oil level.
Clean the windshield, windshield wipers, headlights, and taillights.

Replacing bulbs
Bulb types vary depending on model and equipment level. If a light bulb 15
breaks, it can
be replaced by following the procedure shown in the Owner's Manual. If you are experiencing problems with any lights other than light bulbs, contact a work- shop 16
.
If there is a problem with an LED 17
light, the
entire lamp unit will normally need to be replaced.
NOTE
For information on lights not mentioned in the Owner's Manual, contact a Volvodealer or a certified Volvo service techni-cian.
WARNING
The vehicle electrical system must be in ignition mode 0 when bulbs are replaced.
CAUTION
Never touch the bulb glass with your bare fingers. Grease and oils from your fingersvaporize in the heat and will leave adeposit on the reflector, which may dam-age it.
NOTE
If the error message persists after the defective bulb has been replaced, we rec-ommend a visit to an authorized Volvoworkshop.
NOTE
Exterior lighting such as headlights and taillights may develop temporary conden-sation on the inside of the lens. This is nor-mal. All exterior lighting is designed toresist this. Condensation is normally ven-ted out of the lamp housing once the lighthas been lit for some period of time.
NOTE
Bulbs for active curve lighting * contain
traces of mercury and should therefore always be submitted to a certified Volvoservice technician.
