1. HEADLIGHT BEAM LEVELER ACTUA-
TOR
1) Turn on the headlights.
2) Confirm the headlight beam level is lowered by
changing the switch position to 0 → 1 → 2 → 3 →
4 → 5.
2. HEADLIGHT BEAM LEVELER SWITCH
Connect the battery, headlight beam leveler switch
connector, circuit tester and resistor (470 Ω) as
shown in the figure. Measure the current at each
switch position.

Headlight Assembly
7) Remove the packing (A) from seal groove.
CAUTION:
Completely remove the packing not to leave
any chips behind.
D: ASSEMBLY
1) Cut the tip of packing (A) at an angle of 45°.
2) With the cut end facing upward, insert the pack-
ing (A) into groove around seal.
CAUTION:
 If the packing protrudes, slowly take it off the
groove.
 Do not stretch the packing. If the packing is
stretched, seal fails.
3) After making a round of the seal, cut its tip at an
angle of 45°, with its length 10 mm (0.39 in) longer
than the circumference of seal so that the tip over-
laps the other. Then, press it onto the seal, using a
screwdriver.4) Match the positions of the lens and headlight as-
sembly, and then insert the lens into headlight as-
sembly.
5) Secure the hook, and then install the clip and
screw.
6) Put the seal portion of headlight assembly into
the water and check that water does not enter in-
side the headlight.
CAUTION:
Be sure that water does not enter inside the
headlight through the bulb socket or ventilation
hole.
E: ADJUSTMENT
1. HEADLIGHT AIMING
CAUTION:
Turn off the light before adjusting headlight
aiming. If the light is necessary to check aim-
ing, do not turn on for more than two minutes.
NOTE:
Before checking the headlight aiming, be sure of
the following:
 The area around the headlight has not sustained
any accident, damage or other type of deformation.
 Vehicle is parked on a level surface.
 The inflation pressure of tires is correct.
 Vehicle’s fuel tank is fully charged.
1) Bounce the vehicle several times to normalize
the suspension.
2) Make certain that someone is seated in the driv-
er’s seat.
3) Turn the headlights on and then adjust the low
beam pattern by following positions on the screen.
NOTE:
 Set the headlight beam leveler switch to “0” posi-
tion.
 Adjust the vertical aim (A) first, then horizontal
aim (B).(A) Packing

Idle Speed
3. Idle Speed
A: INSPECTION
1) Before checking idle speed, check the following:
(1) Ensure the air cleaner element is free from
clogging, ignition timing is correct, spark plugs
are in good condition, and the hoses are con-
nected properly.
(2) Ensure the malfunction indicator light does
not illuminate.
2) Warm-up the engine.
3) Stop the engine, and then turn the ignition switch
to OFF.
4) When using the Subaru Select Monitor, refer to
the following. TOOL, PREPARATION TOOL, General Descrip-
tion.>
(1) Insert the cartridge to Subaru Select Moni-
tor.
(2) Connect the Subaru Select Monitor to data
link connector.
(3) Turn the ignition switch to ON, and Subaru
Select Monitor switch to ON.
(4) Select the {Each System Check} in Main
Menu.
(5) Select the {Engine Control System} in Se-
lection Menu.
(6) Select the {Current Data Display & Save} in
Engine Control System Diagnosis.
(7) Select the {Data Display} in Data Display
Menu.
(8) Start the engine, and then read the engine
idle speed.
5) When using the tachometer (Secondary pick-up
type).
(1) Attach the pick-up clip to No. 1 cylinder
spark plug cord.(2) Start the engine, and then read the engine
idle speed.
NOTE:
 When using the OBD-II general scan tool, care-
fully read its operation manual.
 This ignition system provides simultaneous igni-
tion for #1 and #2 plugs. It must be noted that some
tachometers may register twice that of actual en-
gine speed.
6) Check the idle speed when unloaded. (With
headlights, heater fan, rear defroster, radiator fan,
air conditioning, etc. OFF)
Idle speed [No load and gears in “N” or “P”
range]:
650
±100 rpm
7) Check the idle speed when loaded. (Turn the air
conditioning switch to “ON” and operate the com-
pressor for at least 1 minute before measurement.)
Idle speed [A/C “ON”, no load and gears in “N”
or “P” range]:
850
±100 rpm
NOTE:
Idle speed can not be adjusted manually, because
the idle speed is automatically adjusted.
If the specified idle speed can not be maintained,
refer to General On-board Diagnosis Table under
“Engine Control System”. Basic Diagnostics Procedure.>

A: INSPECTION
1. USING SUBARU SELECT MONITOR
1) Before checking the idle speed, check the fol-
lowing:
(1) Ensure the air cleaner element is free from
clogging, ignition timing is correct, spark plugs
are in good condition, and that the hoses are
connected properly.
(2) Ensure the malfunction indicator light does
not illuminate.
2) Warm-up the engine.
3) Stop the engine, and then turn the ignition switch
to OFF.
4) Insert the cartridge to Subaru Select Monitor.
5) Connect the Subaru Select Monitor to data link
connector.
6) Turn the ignition switch to ON, and Subaru Se-
lect Monitor switch to ON.
7) Select the {2. Each System Check} in Main
Menu.
8) Select the {Engine Control System} in Selection
Menu.
9) Select the {1. Current Data Display & Save} in
Engine Control System Diagnosis.
10) Select the {1.12 Data Display} in Data Display
Menu.
11) Start the engine, and then read the engine idle
speed.
12) Check the idle speed when unloaded. (With
headlights, heater fan, rear defroster, radiator fan,
air conditioning, etc. OFF)
Idle speed [No load and gears in neutral]:
700
±100 rpm
13) Check the idle speed when loaded. (Turn the
air conditioning switch to “ON” and operate the
compressor for at least 1 minute before measure-
ment.)
Idle speed [A/C “ON”, no load and gears in neu-
tral]:
A/C Refrigerant pressure (LOW)
MT: 725
±100 rpm
AT: 750
±100 rpm
A/C Refrigerant pressure (HIGH)
MT: 800
±100 rpm
AT: 825
±100 rpm
NOTE:
As idle speed is controlled by the automatic adjust-
ment type, it can not be adjusted manually. If the
idle speed is out of specifications, refer to General
On-board Diagnosis Table under “Engine Control
System”. tics Procedure.>
