How long should you keep the coolant
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 Pontiac dealer in the area where
you’ll be parking your vehicle. The dealer
can give you the best advice for that
particular area.
Autamatic Transmission
There are several different positions for
your shift lever.
P (Park)
This locks your rear wheels. It’s the best
position to use when you start your
engine because your vehicle can’t move
easily.

ProCarManuals.com

Ensure the shift lever is fully in “P”
(Park) range before starting the engine.
Your Pontiac has a brake-transmission
shift interlock. You have to fully apply
your regular brakes before you can shift
from
“P” (Park) when the ignition key is
in the “Run” position. If you cannot shift
out of
“P’ (Park), ease pressure on the
shift lever
- push the shift lever all the
way into “P” (Park) and also release the
shift lever button on floor shift console
models as you maintain brake application.
Then move the shift lever into the gear
you wish. (Press the shift lever button
before moving the shift lever on floor
shift console models.) See “Shifting out
of
“P” (Park)” in this part.
R (Reverse)
Use this gear to back up.
NOTICE:
Shifting to “R” (Reverse) while your
vehicle is moving forward could
damage your transmission. Shift to
“R’ only after your vehicle is
stopped.
To rock your vehicle back and forth to
get out of snow, ice or sand without
jamaging your transmission, see “Stuck:
[n Sand, Mud, Ice or Snow, If You’re”
In the Index.
@ N (Neutral)
[n this position, your engine doesn’t
:onnect with the wheels.
To restart when
You’re already moving, use
“N” (Neutral)
mly. Also, use
“N’ when your vehicle is
Jeing towed.
NOTICE:
Damage to your transmission caused
by shifting out of
“P” (Park) or “N”
(Neutral) with the engine racing isn’t
covered by your warranty.

@ Automatic Overdrive
This position is for normal driving. If you
need more power far passing, and you’re:
- Going less than about 35 mph
(56 kdh), push your accelerator
pedal about halfway down.
- Going about 35 mph (56 km/h) or
more, push the accelerator all
the way
down.
You’ll shift down to the
next gear and
have more power.
D (Third Gear)
This is like @ , but you never go into
Overdrive.
Here are some times you might choose
“D’ instead of @ :
- When driving on hilly, winding roads
- When towing a trailer, so there is less
shifting between gears
- When going down a steep hill
2 (Second Gear)
This position gives you more power but
lower fuel economy.
You can use “2” on
hills. It can help control your speed as
you go down steep mountain roads, but
then you would also want to use your
brakes off and on.
NOTICE:
Don’t drive in “2” (Second Gear)
for more than
5 miles (8 km), or at
speeds over
55 mph (88 kmh), or
you can damage your transmission.
Use
(EJ or “D” as much as possible.
Don’t shift into
“2” unless you
are going slower than
65 mph
( 105 km/h), or you can damage
your engine.
1 (First Gear)
This position gives you even more power
(but lower fuel economy) than
“2.” You
can use it on very steep hills, or in deep
snow or mud. If the selector lever is put
in
“I,” the transmission won’t shift into
first gear until fhe vehicle is going slowly
enough.
NOTICE:
If your rear wheels can’t rotate, don’t
try to drive. This might happen if you
were stuck in very deep sand or mud
or were up against a solid object.
You
could damage your transmission.
Also, if you stop when going uphill,
don’t hold your vehicle there with
only the accelerator pedal. This could overheat and damage the transmission. Use your brakes or
shift into
“P” (Park) to hold your
vehicle in position on a hill.
Maximum engine speed is limited
to
protect driveline components from improper operation.

Your six-speed manual transmission
has a feature that allows you to safely
shift into
“R’ (Reverse) while the vehicle
is rolling (at less than 3 mph). You will be
“locked-out” if you try to shift into “R”
(Reverse) while your vehicle is’ moving
faster than
3 mph.
If you have turned your ignition off and
wish to park your vehicle in Reverse, you
will have to move the shift lever quickly
to the right, “crashing” through the high
load spring and then into gear.

Limited-Slip Rear Axle
If you have this feature, your rear axle
can give you additional traction on
snow, mud, ice, sand or gravel. It works
like a standard axle most of the time,
but
when one of the rear wheels has
no traction and the other does, the limited-slip feature will allow the
wheel with traction to move the vehicle.

Warning Lights, Gages
and Indicators
This section describes the warning lights
and gages that may be on your vehicle.
The pictures will help you locate them.
Warning lights and gages can signal that
something is wrong before
it becomes
serious enough to cause
an expensive
repair or replacement. Paying attention to
your warning lights and gages could also
save you or others from injury.
Warning lights go on when there may be
or is a problem with one of your vehicle’s
functions.
As you will see in the details
on the next few pages, some warning
lights come on briefly when you turn the
ignition key just to let you know they’re
working. If you are familiar with this
section, you should not be alarmed when
this happens.
Gages can indicate when there may be or
is a problem with one of your vehicle’s
functions. Often gages and warning lights
work together to let you know when
there’s a problem with your vehcle. When
one of the warning lights comes on
and stays on when you are driving, or
when one
of the gages shows there may
be a problem, check the section that tells
you what to do about it. Please follow the
manual’s advice. Waiting to do repairs
can be costly
- and even dangerous. So
please get to know your warning lights
and gages. They’re a big help.
