Oil Pressure Indicator
(3.1L V6 ENGINE)
Your vehicle is equipped with an oil
pressure indicator rather than an oil
pressure gage. Your oil pressure
indicator lets you know when you may
have a problem with your engine
oil
pressure.
When the engine is running, readings
within the white graduation band
indicate the normal operating range.
Readings in or below the red area
indicate that the engine’s
oil level may
be dangerously low, or there may be
another problem causing low
oil
pressure.
Driving your vehicle with low oil
pressure can cause extensive engine damage. Have your vehicle serviced
immediately. ndt
keep driving if the
oil
- r-- ssure is low. If you do,
your engine can become
so hot that
it catches fire. You or others could
be burned. Check your
oil as soon
serviced.

Damage to your engine from
neglected oil problems can be
costly and is not covered by your
Oil Pressure Gage
(3800 V6 ENGINE)
Your oil pressure gage shows the oil
pressure in psi (pounds per square inch)
when the engine
is running. Canadian
vehicles indicate pressure in
kPa
(kilopascals). Oil pressure may vary
with engine speed, outside temperature
and
oil viscosity. In fact, while the
engine is warming up, the
oil pressure
will be higher than at the normal
operating temperature. Readings above
the red warning zone indicate the
normal operating range.
If the gage reads in the red warning
zone, your engine’s
oil level may be
dangerously low or there may be
another problem causing low
oil
pressure.

SG
“SG” must be on the oil container,
either by itself or combined with other
quality designations, such as
“SGICC,” “SGICD,” “SF, SG, CC,”
etc. These letters show American
Petroleum Institute
(API) levels of
quality.
If you use oils that don’t have the
SG designation? you can cause
engine damage not covered by your
warranty.
Grade E
For best fuel economy and cold starting,
select the lowest SAE viscosity grade oil
for the expected temperature range.
SAE 5W-30 (3.X V6 Engine)
As shown in the viscosity chart, SAE
5W-30 is best for your vehicle.
However, you can use
SAE 1OW-30 if
it’s going to be 0°F (-18°C) or above.
These numbers on
an oil container
show
its viscosity, or thickness. Do
not use other viscosity oils such as
SAE 1OW-40 or SAE 20W-50.

What Kind of Oil to Use (CONI)
SAE 1OW-30 (3800 V6 Engine)
As shown in the viscosity chart, SAE
1OW-30 is best for your vehicle.
However, you can use
SAE 5W-30 if
it's going to be colder than
60°F
(16°C) before your next oil change.
When it's very cold, below
0°F
(-18" C), you should use SAE 5W-30.

Explanation of Scheduled Maintenance Services
Below are explanations of the services listed in Schedule I
and Schedule II.
The proper fluids and lubricants to use are listed in
Section D. Make sure whoever services your vehicle uses
these. All parts should be replaced
and all necessary repairs
done before you or anyone else drives the vehicle.

1 Engine Oil and Filter Chang@-Always use SG
Energy Conserving
II oils of proper viscosity. The
“SG” designation may be shown alone or in
combination with others, such as “SG/CC,” “SG/CD,” or
“SF, SG, CC,” etc. To determine the
preferred viscosity for your vehicle’s engine (e.g.,
SAE 5W-30 or SAE 10W-30), see the
Index under
Engine Oil.
2 Chassis Lubrication-Lubricate the transaxle shift
linkage, parking brake cable guides, underbody
contact points and linkage. Lubricate the front
suspension and steering linkage. NOTE:
To determine your engine’s displacement and code,
see the
Index under Engine IdentiJication.
ITEM
NO. SERVICE
3 Throttle Body Mounting Bolt Torque (3.a
Code D engine only) *-Check the torque of the
mounting bolts and/or nuts.
4 Tire and Wheel Rotation and Inspection-For
proper wear and maximum tire life, rotate your
tires following the instructions
in this manual. See
the
Index under Eres, Inspection & Rotation.
Check the tires for uneven wear or damage. If you
see irregular or premature wear, check the wheel
alignment. Check for damaged wheels
also.
