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.

;kip Shift Light (5.7L LT1 Engine)
Yhen this light comes on, you can only
hift from
“1” (First) to “4” (Fourth) gear
nstead of “1” (First) to “2” (Second)
gar. This helps you to get
the best
lossible fuel economy.
’his light will come on under these
onditions:
The engine coolant temperature is greater than 170°F (77”C),
You are going
15-20 mph
(24-32
km/h), and
You are
at 35% throttle or less. When this
light
is on, the gear shift lever
will let you shift from
“1” (First) gear to
“4”(Fourth) gears only. Once you are
in
“4” (Fourth) gear, you can press the
clutch again and shift into another gear.
Follow the shift speeds in this chart when
the
“SKIP SHIFT” light is on.

Each time you come to
a stop, the
engine’s Electronic Control Module
(EGM) determines when to activate the
“SKIP SHIFT” upshift system. Use
“2”
(Second) gear only when you accelerate
very quickly from’a stop.
You can then
follow the full gear shift pattern.

When this warning light is on, the system
will not limit wheel spin. Adjust your
driving accordingly.
Low Traction Light
When your anti-lock system is adjusting
brake pressure to help avoid a braking
skid, the “LOW TRAC” light will appear
on your instrument cluster. If you have
the traction control system, this light will
also come on when the system is limiting
wheel spin. Slippery road conditions may
exist if this light comes on,
so adjust your
driving accordingly. The light will stay
or
for a few seconds after the anti-lock
system stops adjusting brake pressure or
the traction control system stops limiting
wheel spin. The “LOW TRAC” light also
comes
on briefly, as a bulb check, when
the engine is started.
Sngine Coolant Temperature Gage
’his gage shows the engine coolant
emperature.
If the gage pointer moves
nto the red area, your engine is too, hot!
t means that your engine coolant fias

onditions, you should pull off the road,
top your vehicle and turn
off the engine
s soon as possible.

Towing a vehicle over rough surfaces
could damage a vehicle. Damage
can occur from vehicle-to-ground
or vehicle-to-wheel-lift-equipment
contact.
To help avoid damage, install
a towing dolly and raise vehicle until
adequate clearance is obtained between

Service and Appearanc’e Care
The proper coolant for your Pontiac will:
0
Give freezing protection down to
-34°F (-37°C).
Give boiling protection up to 262°F
(128°C)
.
Protect against rust and corrosion.
Help keep the proper engine
temperature.
Let the warning lights work as
they
should.
What to Use:
Use a mixture of one-half clean water
(preferably distilled) and one-half
antifreeze that meets
“GM Specification
1825M,” which won’t damage aluminum
parts. You can also use a recycled coolant
conforming to GM Specification 1825M
with a complete coolant flush and refill. If
you use this mixture, you don’t need to
add anything else.
NOTICE:
If you use an improper coolant mix,
your engine could overheat and be
badly damaged. The repair cost wouldn’t be covered by your war-
ranty. Too much water in the mix can
freeze and crack the engine, radiator,
heater core and other parts.
Adding Coolant
To Check Coolant: When your engine is
cold, check the dipstick on the cap of the
coolant recovery tank. The coolant level should be “COLD,” or a little higher.
When your engine is warm, the level on
the dipstick should be up to
“HOT,” or a
little higher.

Service and Appearance Care
Radiator Pressure Cap (All Engines)
NOTICE:
Your radiator cap is a 18 psi (124 kPa)
pressure-type cap and must be tightly
installed to prevent coolant loss and
possible engine damage from over-
heating. Be sure the arrows on the
cap line up with the overflow tube
on the radiator filler neck.
When you replace your radiator pressure
cap,
an AC@ cap is recommended.
Thermostat
Engine coolant temperature is controlled
by a thermostat in the engine coolant
system. The thermostat stops the flow of
coolant through the radiator until the
coolant reaches a preset temperature.
When you replace your thermostat, an
AC@ thermostat is recommended.

How to Check Power Steering Fluid:
Unscrew the cap and wipe the dipstick
with a clean rag. Replace the cap and
completely tighten it. Then remove the
cap again and look at the fluid level on
the dipstick.

Chassis Lubrication
- Lubricate
the suspension and steering
linkage. Lubricate the
transmission
shift linkage.
Tire and Wheel Rotation and
InsDection
- For proper wear
and maximum tire life, rotate
your tires following the
instructions in this manual. See
“Tires, Inspection and Rotation”
in the Index. Check the tires for
uneven wear or damage. If you
see irregular or premature wear,
check the wheel alignment.
Check for damaged wheels also.

- Inspect the belt(s)
for cracks, fraying, wear and
proper tension. Replace as

5 Cooling: System Service* -
Drain, flush and refill the system
with new or approved recycled
coolant conforming to GM
Specification 1825M. Keep
coolant at the proper mixture as specified. See “Coolant”
in the
Index. This provides proper
freeze and boil protection, corrosion inhibitor level and
maintains proper engine operating temperature.
Inspect hoses and replace if they
are cracked, swollen or deterior-
ated. Tighten screw-type hose
clamps. Clean the outside of the
radiator and air conditioning
condenser. Wash the pressure cap and neck.
To help ensure proper operation,
we recommend a pressure test of
both the cooling system and the
pressure cap.
