Disposal of Pretensioner
6. Disposal of Pretensioner
A: CAUTION
 Do not discard undeployed pretensioners, because
they may cause serious personal injury when acci-
dentally deployed.
 Deployment of the pretensioners should be done
on a flat place free from any possible danger. Avoid
deploying outdoors during heavy rainy or strong
windy weather.
 Do not drop or damage the pretensioner.
 Because deploying the pretensioners causes a
high-explosive noise, be sure to warn people in the
area, and do not allow anyone within a 5 m (16 ft)
radius of the disposal site.
 Some smoke will be emitted after deployment of
the pretensioners. Therefore, it must be deployed
in a well-ventilated area with no smoke alarms
nearby.
 Wear gloves, goggles, and earplugs during this
operation. Wash your hands afterwards.
 After deployment, the pretensioner is especially
hot. Leave it unattended for 40 minutes or longer,
and then discard it.
 Do not let water get on the deployed pretension-
er.
 Wrap the deployed pretensioner in an airtight vi-
nyl bag, and then discard it.
 If circumstances do not permit pretensioner de-
ployment, contact a SUBARU dealer.
B: OPERATION
1. DEPLOYING OF PRETENSIONER WHILE
INSTALLED IN VEHICLE

 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.

 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.
