Bulb Replacement

The headlamp isasemi-sealed beamtypewhich usesa
replaceable halogenbulb.Thebulb canbereplaced fromthe
engine compartment sidewithout removing theheadlamp body.

• Grasp onlytheplastic basewhen handling thebulb. Never
touch theglass envelope.

1. Disconnect thebattery cable.
2. Disconnect theharness connector fromtheback sideofthe
bulb.
3. Turn thebulb retaining ringcounterclockwise until
it
is free
from theheadlamp reflector,andthen remove it.
4. Pull offthe rubber cap.
5. Remove theheadlamp bulbcarefully. Donot shake orrotate
the bulb when removing it.
6. Install inthe reverse orderofremoval.

CAUTION:
• Do not leave headlamp reflector withoutbulbforalong
period oftime. Dust,moisture, smoke,etc.entering head-
lamp bodymayaffect theperformance ofthe head lamp.
Remove headlamp bulbfrom thehead lamp reflector just
before areplacement bulbisinstalled.

If any aimer isnot available, aimingadjustment canbedone as
follows:

For details, refertothe regulations inyour owncountry.
CAUTION:
• Keep alltires inflated tocorrect pressures.
• Place vehicle andtester onone and same flatsurface.
• See thatvehicle isunloaded (exceptforfull levels of
coolant, engineoiland fuel, andspare tire,jack andtools).
Have thedriver orequivalent weightplaced indriver's seat.

Q :
Fuel vapor

Theevaporative emissionsystemisused toreduce hydrocar-
bons emitted intotheatmosphere fromthefuel system. This
reduction ofhydrocarbons isaccomplished byactivated char-
coals inthe EVAP canister.
The fuelvapor fromsealed fueltank isled into theEVAP can-
ister when theengine isoff. The fuelvapor isthen stored inthe
EVAP canister. TheEVAP canister retainsthefuel vapor until
the EVAP canister ispurged byair.
When theengine isrunning, theairisdrawn through thebot-
tom ofthe EVAP canister. Thefuel vapor willthen beled tothe
intake manifold.
When theengine runsatidle, theEVAP canister purgecontrol
valve isclosed. Onlyasmall amount ofvapor flowsintothe
intake manifold throughtheconstant purgeorifice.
As the engine speedincreases andthethrottle vacuum rises,
the purge control valveopens. Thevapor issucked through
both main purge andconstant purgeorifices.

Pressure Check

• When reconnecting fuelline, always usenew clamps.
• Make surethatclamp screwdoesnotcontact adjacent
parts.
• Use atorque drivertotighten clamps.
• Use Pressure Gaugetocheck fuelpressure.
• Donot perform fuelpressure checkwithsystem operating.
Fuel pressure gaugemayindicate falsereadings.

1. Release fuelpressure tozero.
2. Disconnect fuelhose between fuelfilter andfuel tube
(engine side).
3. Install pressure gaugebetween fuelfilter andfuel tube.
4. Start engine andcheck forfuel leakage.
5. Read theindication offuel pressure gauge.

At idling:
With vacuum hoseconnected

With vacuum hosedisconnected
Approximately 294kPa (2.94 bar,3.0kg/cm

If results areunsatisfactory, performFuelPressure Regula-
tor Check.

Fuel Pressure Regulator Check

1. Stop engine anddisconnect fuelpressure regulator vacuum
hose fromintake manifold.
2. Plug intake manifold witharubber cap.
3. Connect variablevacuumsourcetofuel pressure regulator.
4. Start engine andread indication offuel pressure gaugeas
