Supercharged Engine (If Equipped)
Your vehicle may have a 3800 Supercharged engine.
The supercharger is a device designed to pump more air
into the engine than it would normally use.
This air,
mixed with fuel, creates increased engine power. Since
the supercharger is a pump and is driven from an engine
accessory drive belt, increased pressure is available at
all driving conditions.
The Powertrain Control Module (PCM), works with a vacuum control to regulate the increased pressure
required during specific driving conditions. When this
increased pressure or boost is not desired, such
as during
idling and light throttle cruising, the excess
air that the
supercharger is pumping is routed through
a bypass.
All of these controls, working together, provide high
performance character and fuel efficiency in the
3800 V6 Supercharged engine.
Engine Oil
CHECK OIL
LEVEL
If the CHECK OIL LEVEL
light on the instrument panel
comes
on, it means you need
to check your engine oil level
right away.
For more
information,
see “Check Oil
Level Light” in the Index. You
should check your engine oil level regularly;
this is
an added reminder.
It’s
a good idea to check your engine oil every time you
get fuel.
In order to get an accurate reading, the oil must
be warm and the vehicle must be on level ground.
Turn
off the engine and give the oil a few minutes to
drain back into the oil pan. If you don’t, the oil dipstic\
k
might not show
the actual level.

How to Check and Add Oil
Check oil only when the engine is cold. Allow the
engine
to cool two to three hours after running.
If you remove the supercharger oil €ill plug while
the engine
is hot, pressure may cause hot oil to
blow out
of the oil fill hole. You may be burned.
Do not remove the plug until the engine cools.
1. Clean the area around the oil fill plug before
2. Remove the oil fill plug using a 3/16 inch
3. The oil level is correct when it just reaches the
bottom of the threads of the inspection hole.
4. Replace the oil plug with the O-ring in place.

Automatic Transaxle Fluid
When to Check and Change
A good time to check your automatic transaxle fluid
level is when the engine oil
is changed.
Change both the fluid and filter every
50,000 miles
(83 000 km) if the vehicle is mainly driven under one
or more of these conditions:
0 In heavy city traflic where the outside temperature
regularly reaches
90°F (32°C) or higher.
In hilly or mountainous terrain.
0 When doing frequent trailer towing.
Uses such as found in taxi, police or delivery service.
If you do not use your vehicle under any of these
conditions, the fluid and filter do not require changing.
See “Scheduled Maintenance Services” in the Index.
How to Check
Because this operation can be a little difficult, you may
choose to have
this done at your Pontiac dealership
Service Department.
If you do it yourself, be sure to follow all the instructions
here, or you could get
a false reading on the dipstick.
