tem is not working properly. Contact your nearest

NOTE This light also comes on when the fuel filler cap is not tightened until it clicks.
If you have recently refueled your vehicle, the cause
of the CHECK ENGINE warning light/malfunction indi-
cator lamp coming on could be a loose or missing
fuel filler cap. Remove the cap and retighten it until it
clicks. Make sure nothing is interfering with the seal-
ing of the cap. Tightening the cap will not make the
CHECK ENGINE warning light turn off immediately. It
may take several driving trips. If the light does not go
out, take your vehicle to your authorized SUBARU
dealer immediately.
If the light is blinking:
If the light is blinking while driving, an engine misfire

belt is loose, broken or if the belt is in good condi-
tion but the light remains on, contact your nearest

vehicle speed reaches about 8 mph (12 km/h). The warning light comes on during driving, but
it goes out immediately and remains off.

such as when the engine is jump started, the ABS
warning light may come on. This is due to the low
battery voltage and does not indicate a malfunction.
When the battery becomes fully charged, the lightwill go out. Brake system warning light
CAUTION
Driving with the brake system warning light
on is dangerous. This indicates your brake
system may not be working properly. If thelight remains on, have the brakes inspected
by a SUBARU dealer immediately. If at all in doubt about whether the brakes are operating properly, do not drive the ve-
hicle. Have your vehicle towed to the nearest
SUBARU dealer for repair.

dropped to near the “MIN” level of the brake fluid
reservoir with the ignition switch in the “ON” position
and with the parking brake fully released.
If the brake system warning light should come on
while driving (with the parking brake fully releasedand with the ignition switch positioned in “ON”), it
could be an indication of leaking of brake fluid or
