Chevrolet MONTE CARLO 1998 Manual page 74

LOCK (B):
Before you put the key into the ignition
switch, the switch is in LOCK. It's also the only position
in
which you can remove your key. This position locks
your ignition, steering wheel and transaxle. It's a
theft-deterrent feature.
OFF (C):
This position lets you turn
off
the engine but
still turn the steering wheel. It doesn't lock the steering
wheel. Use OFF if you must have your vehicle pushed
or towed.
RUN (D):
This position is where the key returns
after you start your vehicle. With the engine off, you
can use RUN to display some of your warning and
indicator lights.
START (E): This position starts your engine.
A warning chime will sound if you open the driver's
door when the ignition is in OFF, LOCK or ACC and
the key is in the ignition.
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 3100 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.
