Gas Cap-The fuel tank filler cap
has a new two-step removal and
installation procedure plus a pres
sure-vacuum safety relief valve. It
is equipped with a double set of
locking tangs.
To remove:
• Rotate cap one-half turn coun
terclockwise to clear the first set
of tangs from the slots inside the
filler neck. This will allow any
residual pressure to escape.
• Pull the cap outward and rotate
one-quarter turn counterclock
wise to clear second set of tangs
and remove the cap.
• To install, reverse this procedure.
NOTE: If this cap requires a re
placement, only a cap with these
same features should be used. Fail

sult in a serious malfunction of the
system. Correct replacement caps
may be obtained from your Au

thoroughly warmed-up).
• Operation in dust storms may
require an immediate oil change.
