Downloaded from www.Manualslib.com manuals search engine The GM Child Love Seat is not recommended for use in the center front
seating position of this vehicle because it may Interfere with quick access
to all front seat belt buckles in an emergency.
To make it easier
to install a GM Child Love Seat in the rear seat of this
vehicle, at least one pre- drilled hole for the top strap anchor bracket has been
provided in the filler
panel between the rear seat and the rear window . It will be
necessary to pierce the trim panel (covering the metal panel Itself) with a hole
that corresponds
to the pre-drilled hole. T 6 find the hole, enter the trunk and
examine the underside of the filler panel. See the booklet that comes with the
Child
Seat for details on locating and mounting the top strap anchor bracket.
When the child
Seat is placed in the car, use the seating position most directly
in front of the anchor bracket and secure the seat using the top strap and the
car lap belt. In using any infant or child restraint system, be sure to read and
follow all instructionsoninstatlatlon and use that come with .the restraint
system.
When not in
use, leave the Love Seat, or other infant or child restraint system,
in place

restraint in the trunk to help keep it from being thrown about and injurying
people in the car during a suddlen maneuver or an accident.

1 . Infants who cannot sit
up· by . themselves should be restrained by placing
them in
a· bassinet, preferably cQvered and padded. Place it crossways in
the vehicle (widthwise) on the rear seat.
The bassinet should be securely
restrained with the vehicle 's regular seat belts. Another method is to place
the bassinet
so that iI rests against the back of the driver 's seat. again

STARTING AND OPERATING
ENGINE EXHAUST GAS CAUTION
(CARBON MONOXIDE)
Do not breathe exhaust gas because it contains carbon monoxide, which by
itself has no color or odor. Carbon monoxide is a dangerous gas. It can cause
unconsciousness and can be lethal.
If
at any time you think exhaust fumes are entering the vehicle, have the cause

CATALYTIC CONVERTER
.Ttle .cal;!ly:tic converter is an emission control device added to the exhaust system,' to reduce exhaust gas pollutants. The converter contains
a ceramic material coated with noble metal catalysts. To prevent contamination
of the catalysts , unleaded gasol;"" must be used . Unleaded gasoline also
reduces spark plug louling. exhaust system corrosion and engine oil
deterioration.
The catalytiC converter requires the use of unleaded gasoline. Using leaded gasoline wilt cause --the converter to lose its effectiveness as an
emission control device. Leaded gasoline will also damage the Computer
Command Control, system oxygen sensor, which could affect emission control,
fuel economy . and drivability.
~,~.,y..'~,","~ ... :..., To help 'prevent damage:
1. Keep your engine properly maintained . Engine malfunctions involving the electrical, carburetion or ignition systems may result in unusually high

materials above the converter. Do not keep driving your vehicle if you
detect engine misfire, noticeable loss of performance ,or other unusual operating conditions. Instead. have it serviced promptly.
