NOTICE: 
Be sure  there  are  no  overhead  obstructions,  such 
as  a  garage  door,  before  you open  the  liftgate. 
You  could  slam  the  liftgate  into  something  and 
break  the  glass. 
To close the liftgate, pull down on the handle, then 
firmly  shut  the liftgate.  Don’t drive with the  liftgate 
open,  even slightly.  See “Engine Exhaust” 
in the Index. 
A light on your  instrument  panel will warn  you  if the 
liftgate 
is not  completely  closed  (see “Door Ajar 
Warning  Light” in the Index). 
It  can  be  dangerous  to  drive  with  the  liftgate  open  because  carbon  monoxide 
(CO) gas can 
come  into  your  vehicle. You can’t  see  or smell 
CO. It can  cause  unconsciousness  and  even  death. 
If you  must  drive  with  the  liftgate  open  or  if 
electrical  wiring  or  other  cable  connections  must 
pass  through  the  seal  between  the  body  and 
the  liftgate: 
0 Make  sure  all  windows  are  shut. 
Turn  the  fan  on  your  heating  or  cooling 
system  to  its  highest  speed 
with the  setting 
on  bi-level  (outside  air  button is pressed). 
That  will force  outside  air  into  your  vehicle. 
See  “Comfort  Controls”  in  the  Index. 
If you  have  air  outlets  on  or  under  the 
instrument  panel,  open  them  all  the 
way. 
See  ‘(Engine  Exhaust”  in  the  Index.

Ignition  Positions 
With the ignition key  in  the ignition switch,  you can turn 
the  switch  to  five  positions. 
C 
ACCESSORY  (A): This  is an on position  in which  you 
can  operate  your electrical power accessories. Press  in 
the  ignition switch  as you  turn  the top 
of it toward you. 
LOCK (B): This  is  the only position in which you can 
remove the  key. This  locks  your steering  wheel, ignition 
and transaxle. 
OFF (C): This  position unlocks the steering  wheel, 
ignition  and transaxle, but does not send electrical 
power  to any accessories. Use this position if your 
vehicle must be pushed  or  towed,  but never try to 
push-start  your vehicle. 
A warning  chime will sound if 
you open  the driver’s door when  the ignition is off and 
the  key is in  the ignition. 
RUN (D): This is an on position to which the switch 
returns after  you start your  engine and release the 
switch. 
The switch stays  in RUN  when the  engine is 
running. But 
even when the  engine  is not running,  you 
can  use  RUN  to  operate your  electrical power 
accessories, and  to display some  instrument panel 
warning lights. 
START (E): This  position  starts  the  engine.  When the 
engine  starts, release the  key. The ignition switch will 
return to RUN  for normal driving. 
Note that even 
if the  engine is not running, the positions 
ACCESSORY and RUN  are positions that allow  you to 
operate  your electrical accessories, such as the radio.

NOTICE: 
If your key  seems  stuck in LOCK and you can’t 
turn  it, be  sure  you are using  the  correct  key;  if 
so, is it all the  way  in? If it is,  then  turn  the 
steering  wheel  left  and  right while  you  turn the 
key  hard.  But turn  the key  only  with  your hand. 
Using 
a tool  to force  it could  break  the key  or the 
ignition  switch. 
If none of this  works,  then your 
vehicle  needs  service. 
Starting Your Engine 
Move  your shift  lever  to PARK (P) or  NEUTRAL  (N). 
Your  engine  won’t start in any  other  position 
-- that’s a 
safety  feature.  To restart  when you’re  already moving, 
use  NEUTRAL 
(N) only. 
NOTICE: 
Don’t try to shift to PARK (P) if your  Oldsmobile 
is  moving. 
If you  do,  you  could  damage the 
transaxle. Shift to 
PARK  (P) only  when  your 
vehicle  is  stopped. 
1. Without pushing  the accelerator pedal, turn your 
ignition key  to START.  When the  engine starts, let 
go of the key.  The  idle  speed will go down as your 
engine  gets warm. 
I NOTICE: 
Holding  your key in START for longer  than 
15 seconds  at a time  will cause  your battery  to be 
drained  much  sooner.  And  the excessive  heat can 
damage your  starter motor.

2. 
3. 
If it doesn’t start right away, hold your key in 
START. If it doesn’t start  in three seconds (or starts 
but then stops), push the accelerator pedal about  one-quarter 
of the way down  for 12 more seconds,  or 
until  it starts. 
If  your engine still won’t start (or starts but  then 
stops),  it could be flooded  with too much gasoline. 
Try this: 
Wait 
15 seconds  to let the starter motor  cool down. 
Then push your accelerator pedal all the  way to the 
floor.  Hold it there. Then hold the key 
in START. 
This clears  the extra gasoline from the engine. When 
the engine starts,  let go 
of the  key and  the accelerator 
pedal. 
If the  engine still doesn’t start,  wait another 
15 seconds and repeat this step. 
NOTICE: 
Your  engine is designed  to  work  with  the 
electronics  in  your  vehicle. If you  add  electrical 
parts  or  accessories,  you could  change  the 
way 
the  engine  operates.  Before  adding  electrical 
equipment,  check  with  your  retailer.  If you  don’t, 
your  engine  might  not  perform  properly. 
If you  ever  have  to  have  your  vehicle  towed,  see 
the  part  of this  manual  that  tells how  to 
do it 
without  damaging  your  vehicle. See “Towing 
Your  Vehicle”  in  the  Index.

Engine Coolant Heater (If Equipped) 3. Plug it  into  a  normal,  grounded  110-volt AC outlet. 
Plugging  the  cord  into 
an ungrounded  outlet 
could  cause  an  electrical  shock.  Also, the  wrong 
kind 
of extension  cord  could  overheat  and  cause 
a fire.  You could  be  seriously  injured.  Plug  the 
cord  into 
a properly  grounded  three-prong 
110-volt 
AC outlet. If the  cord  won’t reach,  use a 
heavy-duty  three-prong  extension  cord  rated  for 
at  least 
15 amps. 
In very  cold weather, 
0°F (- 18 “C) or colder, the  engine 
coolant  heater  can help.  You’ll  get  easier  starting and 
better  fuel economy  during  engine  warm-up.  Usually, 
the  coolant  heater should be plugged in  a minimum  of 
four  hours prior  to  starting your vehicle. 
To Use the  Engine  Coolant Heater 
1. Turn off the  engine. 
2. Open the hood and unwrap  the  electrical  cord. 
4. Before starting the engine,  be sure to unplug and 
store  the cord  as it was before  to keep  it away  from 
moving  engine parts. 
If you don’t, it could 
be  damaged. 
How  long should 
you keep the  coolant heater plugged 
in?  The  answer depends on the  outside temperature, the 
kind 
of oil you  have, and some  other things.  Instead of 
trying to list  everything  here,  we ask  that  you contact 
your retailer  in the area where  you’ll  be parking your 
vehicle.  The retailer can  give 
you the best advice  for  that 
particular  area.
