NOTICE:
Damage to your transaxle caused by shifting out of' PARK (P) or
NEUTRAL (N) with the engine racing isn't covered by your
warranty.
NOTICE:
If your vehicle seems to start up rather slowly, or if it seems
not to shift gears
as you accelerate, something may be wrong
with
a transaxle system sensor. If you drive very far that way,
your vehicle can be damaged. So, if this happens? have
your vehicle serviced right away. Until then, you can use
SECOND (2) when you are driving less than 3S mph (55 km/h)
and AUTOMATIC OVERDRIVE (@!) for higher speeds.

Downloaded from www.Manualslib.com manuals search engine Daytime Running Lamps (Canada Only)
Daytime Running Lamps (DRL) can make it easier for others to see the
front of your vehicle during the day. DRL can be helpful in many
different driving conditions,
but they can be especially helpful in the short
periods after dawn
and before sunset.
A light sensor on top of the instrument panel makes the DRL work, so be
sure it isn't covered.
The
DRL system will make your low beam headlamps come on at
reduced brightness
when:
The ignition is on
Thc headlamp switch is off, and
The transaxle is not in PARK (,P).
When it's dark enough outside, your low beam headlamps will change to
full brightness. When it's bright enough outside, the regular lamps will go
off, and your low beam headlamps change to the reduced brightness of
D RL.
To idle your vehicle with the DRL off shift the transaxle into PARK (P).
The DRL will stay off until you shift out of PARK (P).
As with anv vehicle, you should turn on the regular headlamp system
when you need it.

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.
0 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.
