inspect your vehicle’s emission controlsystem. If your vehicle does not pass thistest, some states may deny renewal ofyour vehicle’s registration.
Your vehicle is equipped with a computerthat monitors the performance of theengine’s emission control system. Certi-fied emissioninspectors will inspect theOn-Board Diagnostic (OBDII) system aspart of the state emission inspectionprocess. The OBDII system is designedto detect engine and transmission pro-blems that might cause the vehicle emis-sions to exceed allowable limits. OBDIIinspectionsapply to all 1996 model yearand newer passenger cars and trucks.Over 30 states plus the District of Colum-bia have implemented emission inspec-tion of the OBDII system.
.The inspection of the OBDII systemconsists of a visual operational check ofthe“CHECK ENGINE”warning light/mal-function indicator light (MIL) and anexamination of the OBDII system with anelectronic scan tool.
.A vehiclepasses the OBDII systeminspection if proper operation of the“CHECK ENGINE”warning light is ob-served, there are no stored diagnostictrouble codes, and the OBDII readinessmonitors are all complete.
.A vehiclefails the OBDII inspection ifthe“CHECK ENGINE”warning light is notproperly operating (light is illuminated or isnot working due to a burned out bulb) orthere is one or more diagnostic troublecodes stored in the vehicle’s computer.
.A state emission inspection may reject(not pass or fail) a vehicle if the number ofOBDII system readiness monitors“NOTREADY”is greater than one. If thevehicle’s battery has been recently re-placed or disconnected, the OBDII systeminspection may indicate that the vehicle isnot ready for the emission test. Under thiscondition, the vehicle driver should beinstructed to drive his/her vehicle for a fewdays to reset the readiness monitors andreturn for an emission re-inspection.
.Owners of rejected or failing vehiclesshould contact their SUBARU Dealer forservice.
Some states still use dynamometers intheir emission inspection program. Adynamometer is a treadmill or roller-liketesting device that allows your vehicle’swheels to turn while the vehicle remains inone place. Prior to your vehicle being puton a dynamometer, tell your emissioninspectornot to place your SUBARUAWD vehicle on a two-wheel dynam-ometer.Otherwise, serious transmis-sion damage will result.
The U.S. Environmental ProtectionAgency (EPA) and states using two-wheeldynamometers in their emission testingprogram have EXEMPTED SUBARUAWD vehicles from the portion of thetesting program that involves a two-wheeldynamometer. There are some states thatuse four-wheel dynamometers in theirtesting program. When properly used, thisequipment should not damage a SUBARUAWD vehicle.
Under no circumstances should the rearwheels be jacked off the ground, norshould the driveshaft be disconnected forstate emission testing.

Tire pressure monitoring
system (TPMS)
The tire pressure monitoring system pro-vides the driver with a warning messageby sending a signal from a sensor that isinstalled in each wheel when tire pressureis severely low.
The tire pressure monitoring system willactivate only when the vehicle is driven atspeeds above 20 mph (32 km/h). Also,this system may not react immediately to asudden drop in tire pressure (for example,a blow-out caused by running over asharp object).
WARNING
If the low tire pressure warning lightilluminates while driving, neverbrake suddenly and keep drivingstraight ahead while gradually redu-cing speed. Then slowly pull off theroad to a safe place. Otherwise anaccident involving serious vehicledamage and serious personal injurycould occur.
Check the pressure for all four tiresand adjust the pressure to the COLDtire pressure shown on the tireplacard on the door pillar on thedriver’s side.
Even when the vehicle is driven avery short distance, the tires getwarm and their pressures increaseaccordingly. Be sure to let the tirescool thoroughly before adjustingtheir pressures to the standardvalues shown on the tire placard.Refer to“Tires and wheels”F11-21.The tire pressure monitoring systemdoes not function when the vehicleis stationary. After adjusting the tirepressures, increase the vehiclespeed to at least 20 mph (32 km/h)to start the TPMS re-checking of thetire inflation pressures. If the tirepressures are now above the severe
low pressure threshold, the low tirepressure warning light should turnoff a few minutes later.
If this light still illuminates whiledriving after adjusting the tire pres-sure, a tire may have significantdamage and a fast leak that causesthe tire to lose air rapidly. If you havea flat tire, replace it with a spare tireas soon as possible.
When a spare tire is mounted or awheel rim is replaced without theoriginal pressure sensor/transmitterbeing transferred, the low tire pres-sure warning light will illuminatesteadily after blinking for approxi-mately one minute. This indicatesthe TPMS is unable to monitor allfour road wheels. Contact yourSUBARU dealeras soon as possiblefor tire and sensor replacement and/or system resetting.
Do not inject any tire liquid oraerosol tire sealant into the tires,as this may cause a malfunction ofthe tire pressure sensors. If the lightilluminates steadily after blinking forapproximately one minute, promptlycontact a SUBARU dealer to havethe system inspected.

3. Turn the hoist shaft end clockwise withthe wheel nut wrench to wind the cable upcompletely until you hear a few clickingsounds.Confirm that the temporary sparetire holding cable has been wound upcompletely by shaking the temporary tire.
CAUTION
If the temporary spare tire is notstored securely, it could damageadjacent areas of the vehicle andmake an abnormal noise.
4. Place the wheel nut wrench andextension back into the tool bag and storethe jackand tool bag in their storagelocations.
5. Fit the lid of the cargo area.
CAUTION
.When stowing a flat tire in thespare tire holder, turn the hoistshaft end only slowly. If it isturned quickly, the wheel disc ofthe flat tire could be damaged.
.Afull-sizeflattireshouldbestowed in the spare tire holderin an emergency only. After hav-ingthe flat tire repaired, immedi-ately swap it with the temporaryspare tire.
.Remember that the tread width ofa flat tire is wider than that of thetemporary spare tire. When car-rying a flat tire stowed in thespare tire holder, make sure thetiredoes not touch any obsta-cles.
Temporary spare tire
WARNING
.Never tow a trailer when thetemporary spare tire is used.The temporary spare tire is notdesigned to sustain the towingload. Use of the temporary sparetire when towing can result infailure of the spare tire and/orless stability of the vehicle andmay lead to an accident.
.When a spare tire is mounted or awheel rim is replaced without theoriginal pressure sensor/trans-mitter being transferred, the lowtire pressure warning light willilluminate steadily after blinkingfor approximately one minute.This indicates the tire pressuremonitoring system (TPMS) is un-able to monitor all four roadwheels. Contact your SUBARUdealer as soon as possible fortire and sensor replacement and/or system resetting.

Jump starting
WARNING
.Battery fluid is SULFURIC ACID.Do not let it come in contact withthe eyes, skin, clothing or thevehicle.
If battery fluid gets on you,thoroughly flush the exposedarea with water immediately. Getmedical help if the fluid hasentered your eyes.
If battery fluid is accidentallyswallowed, immediately drink alarge amount of milk or water,and obtain immediate medicalhelp.
Keep everyone including chil-dren away from the battery.
.The gas generated by a batteryexplodes if a flame or spark isbrought near it. Do not smoke orlight a match while jump starting.
.Never attempt jump starting if thedischarged battery is frozen. Itcould cause the battery to burstor explode.
.Whenever working on or arounda battery, always wear suitable
eye protectors, and remove metalobjects such as rings, bands orother metal jewelry.
.Be sure the jumper cables andclamps on them do not haveloose or missing insulation.Do not jump start unless cablesin suitable condition are avail-able.

not be functioning normally. In this event,go to a SUBARU dealer to have thesystem inspected as soon as possible.
While the vehicle is driven, friction be-tween tires and the road surface causesthe tires to warm up. After illumination ofthe low tire pressure warning light, anyincrease in the tire pressures caused byan increase in the outside air temperatureor by an increase in the temperature in thetires can cause the low tire pressurewarning light to turn off.
System resetting is necessary when thewheels are changed (for example, aswitch to snow tires) and new TPMSvalves are installed on the newly fittedwheels. Have this work performed by aSUBARU dealer following wheel replace-ment.
It may not be possible to install TPMSvalves on certain wheels that are on themarket. Therefore, if you change thewheels (for example, a switch to snowtires), use wheels that have the same partnumber as the standard-equipmentwheels. Without four operational TPMSvalve/sensors on the wheels, the TPMSwill not fully function and the warning lightin the instrument panel will illuminatesteadily after blinking for approximatelyone minute.
When a tire is replaced, adjustments arenecessary to ensure continued normaloperation of the tire pressure monitoringsystem. As with wheel replacement, there-fore, you should have the work performedby a SUBARU dealer.
WARNING
If the low tire pressure warning lightdoes not illuminate briefly after theignition switch is turned ON or thelight illuminates steadily after blink-ing for approximately one minute,you shouldhave your Tire PressureMonitoring System checked at aSUBARU dealer as soon as possi-ble.
If this light illuminates while driving,never brake suddenly and keepdriving straight ahead while gradu-ally reducing speed. Then slowlypull off the road to a safe place.Otherwise an accident involvingserious vehicle damage and seriouspersonal injury could occur.
If this light still illuminates whiledriving after adjusting the tire pres-sure, a tire may have significantdamage and a fast leak that causesthe tire to lose air rapidly. If you havea flat tire, replace it with a spare tire
as soon as possible.
When a spare tire is mounted or awheel rim is replaced without theoriginal pressure sensor/transmitterbeing transferred, the low tire pres-sure warning light will illuminatesteadily after blinking for approxi-mately one minute. This indicatesthe TPMS is unable to monitor allfour road wheels. Contact yourSUBARU dealer as soon as possiblefor tire and sensor replacement and/or system resetting. If the lightilluminates steadily after blinkingfor approximately one minute,promptly contact a SUBARU dealerto have the system inspected.
&Tire inspection
Checkon a daily basis that the tires arefree from serious damage, nails, andstones. At the same time, check the tiresfor abnormal wear.
Contact your SUBARU dealer immedi-ately if you find any problem.
NOTE
.When the wheels and tires strikecurbs or are subjected to harsh treat-ment as when the vehicle is driven on arough surface, they can suffer damage
