Hatch
A CAUTION:
It can be dangerous to drive with the rear
swing-out windows, rear hatch or rear doors
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 rear swing-out
windows, rear hatch or rear doors open or
if
electrical wiring or other cable connections must
pass through the seal between the body and the
rear swing-out windows, rear hatch or rear doors:
Make sure all windows are shut.

See “Engine Exhaust” in the Index.
Rear Hatch and Dutch Doors Release
(Option)
If you have this option, your vehicle must be in either
PARK (P) or NEUTRAL
(N) to release the hatch and
unlock the Dutch doors. If your battery
is dead, the
hatch and Dutch doors will not open,
even from the
outside with a key.
To release the hatch and
unlock the doors from the
inside of the vehicle, press
the REAR HATCH button
on the instrument panel.
It
is located on the right side of the steering column. The
hatch will release with or without the key
in the ignition.
Then, pull up on
the hatch handle and open the doors.

Ignition Positions
Use your ignition key to start your vehicle. The ignition key \
lets you turn the ignition switch
to five different positions.
C
ACCESSORY (A): This position lets you use things like
the radio and the windshield wipers when the engine is
off. To get into ACCESSORY, push in the key and turn
it toward
you. Your steering wheel will remain locked,
just as it was before
you inserted the key.
NOTICE:
Don’t operate accessories in the ACCESSORY
position for long periods
of time. Prolonged
operation of accessories in the ACCESSORY
position could drain your battery and prevent
you from starting your vehicle.
LOCK (B): This position locks your ignition, steering
wheel and transmission shift lever
in PARK (P). It’s a
theft-deterrent feature. You will only be able to remove
your key when the ignition is turned to
LOCK.
OFF (C): This position lets you turn off the engine but
still turn the steering wheel. Use
OFF if you must have
your vehicle in motion while the engine is off (for
example,
if your vehicle is being towed).
RUN (D): This is the position for driving.
START (E): This starts your engine.

NOTICE:
If your key seems stuck in LOCK and you can’t
turn it, be sure it is 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 vehicle is
moving. If you do, you could damage the
transmission. 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. ,

2-15

2. If it doesn’t start right away, hold your key in
START. If it doesn’t start in 10 seconds, push the
accelerator pedal
all the way down for five more
seconds, or until it starts.
3. If your engine still won’t start (or starts but then
stops), wait
15 seconds and start over.
When the engine starts, let go
of the key and the
accelerator pedal.
I 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 dealer. 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.
Fuel Regulator
You have a fuel regulator that shuts the fuel off when the
engine reaches
5,600 rpm.
Engine Coolant Heater (Option)
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.
3 IL

To use the coolant heater:
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
3. Plug it into a normal, grounded 110-volt AC outlet.
I
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.
4. After you’ve used the coolant heater, be sure to 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
GM dealer in the area where you’ll be parking your
vehicle. The dealer can give
you the best advice for that
particular area.

Automatic Transmission Operation
There are several different positions for your shift lever.
PARK (P): This locks your rear wheels. It’s the best
position to use when you start your engine because your
vehicle can’t move easily.
, ’
I
It is dangerous to get out of your vehicle if the
shift lever
is not fully in PARK (P) with the
parking brake firmly set. Your vehicle can roll.
CAUTION: (Continued)
I I
I CAUTION: (Continued)
Don’t leave your vehicle when the engine
is
running unless you have to. If you have left the
.engine running, the vehicle can move suddenly.
You or others could be injured. To be sure your
vehicle won’t move, even when you’re on fairly
level ground, always set your parking brake and
move the shift lever to
PARK (P).
See “Shifting Into PARK (P)” in the Index. If
you’re pulling a trailer, see “Towing a Trailer”
in the Index.
I
v
Ensure the shift lever is fully in PARK (P).range
before starting the engine. Your vehicle has a
brake-transmission shift interlock. You have to fully
apply your regular brakes before you can shift from
PARK
(P) when the ignition key is in the RUN position.
If you cannot shift out of PARK
(P), ease pressure on’
the shift lever
-- push the shift lever all the way into
PARK (P) as you maintain brake application. Then
move the shift lever into the gear you wish. See
’‘Shifting Out of PARK
(P)” in this section.
