There are two things the system
docsrl’r
do:
It
can’t sense heavy
dust
in
the
places
where you drive.
If
you drive
in
a
dusty
area,
you should change
your
oil
every
3,000
miles
(5
000
km)
or
three months (whichever comes first) unlesi the display says to change
it
eve11 somer than
that.

It
doesn’t check
IIOCV
much
oil you have, so you‘ll
still
have to check for
that.
To
see how, see “Engine
Oil“
in
the
Index.
Electronic Level Control
The Electronic Level Control
(ELC)
system autonmtically
adjusts
the rear
trim
height
in
response
to
changes
in
vehicle loading. The system consists
of
an
air
compressor
assembly,
air
drver,
exhaust solcnoici, compressor
relay,
height sensor, air adjustable
shocks
and
air tubing. The compressor
is activated
when
the ignition
is
on and
a
sufficient amount of weight is
added
to
the car to cause the rear suspension to deflect more than
approximately one inch. The exhaust solenoid
is
powered
at
all
times,
allowing the system to exhaust with the ignition off when excess weight
is
removed from the vehicle.
If
the system has a slight leak, the air compressor
will
run frequently for
a
few seconds each time.
For
a
larger air leak the
air
compressor may stay on for
up
to seven
minutes. You should see your dealer for service, but
you
can keep driving
lyour Cadillac.
