ignition OLDSMOBILE SILHOUETTE 2003 Repair Manual

If you put things inside your vehicle - like suitcases,
tools, packages, or anything else
- they will go as fast
as the vehicle goes.
If you have to stop or turn
quickly, or
if there is a crash, they'll keep going.
Things you put inside your vehicle can strike
and injure people in a sudden stop or turn,
or
in a crash.
Put things in the cargo area of your
vehicle.
Try to spread the weight evenly.
Never stack heavier things, like suitcases,
inside the vehicle
so that some of them
are above the tops
of the seats.
Don't leave an unsecured child restraint
in your vehicle.
0 When you carry something inside the
vehicle, secure
it whenever you can.

Automatic Level Control
On vehicles equipped with the automatic level control,
the rear of the vehicle is automatically kept level as you
load or unload your vehicle. However, you should still
not exceed the GVWR or the GAWR.
If the engine is running or the ignition key is in
ACCESSORY or when Retained Accessory Power (RAP)
is active, you may hear the compressor operating when
you load or unload your vehicle, and periodically as the
system self-adjusts. This is normal. See "Retained
Accessory Power" under
Ignition Positions on page 2-32.
The compressor should operate for brief periods of time.
If the sound continues for an extended period of
time, your vehicle needs service.
Using heavier suspension components to get added
durability might not change your weight ratings. Ask your
dealer to help you load your vehicle the right away.

How to Reset the Change Engine
Oil Message
The GM Oil Life System calculates when to change your
engine oil and filter based on vehicle use. Anytime your
oil is changed, reset the system
so it can calculate when
the next oil change is required.
If a situation occurs where
you change your oil prior to a change engine oil message
being turned on, reset the system.
1. With the ignition key in RUN but the engine off,
repeatedly push the tripheset button until OIL is
displayed on the Driver Information Center (DIC).
2. Once OIL is displayed, push and hold the tripheset
button for five seconds. The number will disappear
and be replaced by
100 (indicating 100% oil life
remaining).
3. Turn the key to OFF.
If the change engine oil message comes back on,
the engine oil life monitor has not reset. Repeat the
procedure.
What to Do with Used Oil
Used engine oil contains certain elements that may be
unhealthy for your skin and could even cause cancer.
Don’t let used oil stay on your skin for very long.
Clean your skin and nails with soap and water, or a
good hand cleaner. Wash or properly dispose of
clothing or rags containing used engine oil. See the
manufacturer’s warnings about the use and disposal
of oil products.
Used oil can be a threat to the environment. If you
change your own oil, be sure to drain all the oil from
the filter before disposal. Never dispose of oil by putting
it in the trash, pouring it on the ground, into sewers,
or into streams or bodies of water. Instead, recycle it
by taking it to a place that collects used oil.
If you
have a problem properly disposing of your used oil,
ask your dealer, a service station or a local recycling
center for help.

on page
5- 12 for more
information on location.
Squeeze the tabs and pull up
on the cap to access
the remote positive
(+) terminal. You should always
use the remote positive
(+) terminal instead of the
positive (+) terminal on your battery.

engine is not running and can injure you.
Keep hands, clothing and tools away from any
underhood electric fan.

To use your air inflator system, do the following:
1. Turn the ignition to ACCESSORY or RUN.
2. Attach the appropriate nozzle adapter, if required,
to the end
of the hose that has the pressure gage.
3. Attach that end of the hose to the object you wish
to inflate.

page 5-96 or see your dealer for service.
