Before closing the hood, be sure all the filler caps are on
properly. Then just pull the hood down and close it firmly.
3800 Supercharged Engine
(If Equipped)
Your vehicle may have a 3800 Supercharged engine.
The supercharger is a device which is 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
Supercharged engine.
Engine Oil
If the LOW 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 ªLow Oil Level Lightº 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.

Supercharger Oil
Unless you are technically qualified and have the proper
tools, you should let your dealer or a qualified service
center perform this maintenance.
When to Check
Check oil level every 30,000 miles (50 000 km) or every
36 months, whichever occurs first.
What Kind of Oil to Use
See ªRecommended Fluids and Lubricantsº in the Index
and use only the recommended oil.
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.
CAUTION:
If you remove the supercharger oil fill 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
removing it.
2. Remove the oil fill plug using a 3/16 inch
Allen wrench.
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. Torque
to 88 lb
-in (10 N´m).
