Ignition Key Positions
Your square-headed key
opgs.@gs ,. .r , your ignition lock. ..
This lock gives you five different positions.
Before you put the key in, your ignition will be in the
Lock position. This position locks your ignition, steering
wheel and transaxle. It’s a theft deterrent feature.
The other positions let you perform these functions:
ACC: Accessory lets you’use things like the radio and
the windshield wipers when the engine is
off. To use
“Acc,” push in the key and turn
it toward you. Your
72

steering wheel will remain locked, just as it was before
you inserted the key.
OFF: This position lets you turn off the engine but still
turn the steering wheel. It doesn’t lock the steering
wheel like “Lock.” Use
“Off’” if you must .have your car
in motion while the engine is
off.
RUN: This is the position for driving.
START This key position starts your engine.
Starting .Your Engine
Engines start differently. The 8th digit of your Vehicle
Identification Number (VIN)
shows the code letter or
number for your engine. You will- find the VIN at the
top
left of your instrument panel. (See “Vehicle
Identification Number” in the Index.) Follow the proper
steps to start the engine.
Move your shift lever to
“P” (Park) or “N” (Neutral).
Your engine won’t start in any other position
-- that’s a
safety feature;
To restart when you’re already moving,
use
“N’ (Neutral) only.

1 To start your L4 2.3 Lites (Code 3) engine:
I
Don’t push the accelerator pedal before starting your
engine. In some other vehicles you might need to do
this, but because of your vehicle’s computer systems,
you don’t.
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.
If it doesn’t start right away, and the weather is very
cold (below
-20’ .F, or -29’ C), push the accelerator
pedal about one-quarter of the way down while you
turn the key to
“Start.” Do this until the engine starts.
As soon as it does, let go of’the key.
4. If your engine still won’t start (or starts but then
stops), it could
be flooded with too much gasoline.
Try pushing your accelerator pedal all the way to the
floor and holding it there as you hold the key in
“Start” for about three seconds. This clears the extra
gasoline from the engine.
If the car starts briefly but
then stops again, do the same thing, but this time
keep the pedal about one-quarter of the way down
for five or six seconds.

Driving Through Deep Standing
Water
If you drive too quickly through deep puddles 01
standing water, water can come in through
engine’s air intake and badly damage your
engine.
If you can’t avoid deep puddles or
standing water, drive through them very slowly.
Engine Block Heater (Option)
In very cold weather, O°F (-18 “C) or colder, the engine
block heater can help. You’ll get easier starting and
better fuel economy during engine warm-up.
To use the block heater:
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
3. Plug it into a normal, grounded 110-volt outlet.
1 A
CAUTION:
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 outlet.
If the cord won’t reach, use a
heavy-duty three-prong extension cord rated for
at least
15 amps.
I
How long should you keep the block heater plugged in?
The answer depends on the weather, the kind of oil you
have, and some other things. Instead
of trying to list
everything here, we ask that you contact a Buick dealer in
the area where you’ll be parking
your vehicle. The dealer
can give you the best advice for that particular area.
