controls the locking and unlocking of the steering
column does not work properly, have the vehicle towed
to a dealer for service.
PULL KEY
- WAIT 10 SEC: If this message comes
on, the steering column lock system has detected a
problem while engaging the steering column lock. This
message may occur when the ignition key is removed
and re
-inserted before the steering column lock system
fully locks or unlocks the steering column. To
acknowledge that you have read this message, and to
clear it from the display, remove the ignition key and
wait 10 seconds before re
-inserting the key into the
ignition. If you attempt to operate your vehicle without
removing the key for 10 seconds, the vehicle's fuel
system will shut off at 1.5 mph (2.4 km/h). If the
message stays on after removing the key and waiting 10
seconds, have your vehicle taken to an authorized dealer
as soon as possible for diagnosis and repair.
LOW OIL PRESSURE: You will hear four chimes and
the CHECK GAGES telltale will come on when this
message is displayed. To acknowledge the warning,
press the RESET button. After you press the RESET
button, a message will be displayed and you will hear a
chime every minute until the vehicle is serviced. If you
do not press RESET, the message will remain on the
digital display until the vehicle is serviced.Low oil pressure may be the result of a combination of
low oil level and abrupt changes in the vehicle's
direction. When this warning is displayed, you should
not operate the engine at high RPM or make fast abrupt
moves. When it is convenient, you should check the oil
level. See ªEngine Oilº in the Index.
LOW OIL LEVEL: Press RESET to acknowledge that
you have read the message and to remove it from the
display. The message will reappear every 10 minutes
until this condition changes.
You will hear two chimes when this message is
displayed. If this message appears after starting your
engine, your engine oil level may be too low. You may
need to add oil. See ªEngine Overheatingº in the Index.
REDUCED ENGINE POWER: You will hear
chimes continuously when this message is displayed.
To acknowledge that you have read the message and
to remove it from the display, press RESET. The
message will reappear every 15 seconds until this
condition changes.

Just before you leave the lane, glance quickly over your
shoulder to make sure there isn't another vehicle in your
ªblindº spot.
Once you are moving on the freeway, make certain you
allow a reasonable following distance. Expect to move
slightly slower at night.
When you want to leave the freeway, move to the proper
lane well in advance. If you miss your exit, do not,
under any circumstances, stop and back up. Drive on to
the next exit.
The exit ramp can be curved, sometimes quite sharply.
The exit speed is usually posted.
Reduce your speed according to your speedometer, not
to your sense of motion. After driving for any distance
at higher speeds, you may tend to think you are going
slower than you actually are.
Before Leaving on a Long Trip
Make sure you're ready. Try to be well rested. If you
must start when you're not fresh
-- such as after a day's
work
-- don't plan to make too many miles that first part
of the journey. Wear comfortable clothing and shoes you
can easily drive in.Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it's ready to go. If it needs
service, have it done before starting out. Of course,
you'll find experienced and able service experts in
Chevrolet dealerships all across North America. They'll
be ready and willing to help if you need it.
Here are some things you can check before a trip:

Windshield Washer Fluid: Is the reservoir full? Are
all windows clean inside and outside?

Wiper Blades: Are they in good shape?

Fuel, Engine Oil, Other Fluids: Have you checked
all levels?

Lamps: Are they all working? Are the lenses clean?

Tires: They are vitally important to a safe,
trouble
-free trip. Is the tread good enough for
long
-distance driving? Are the tires all inflated to the
recommended pressure?

Weather Forecasts: What's the weather outlook
along your route? Should you delay your trip a short
time to avoid a major storm system?

Maps: Do you have up
-to-date maps?

6-61 Finish Care
Occasional waxing or mild polishing of your vehicle by
hand may be necessary to remove residue from the paint
finish. You can get GM
-approved cleaning products
from your dealer. (See ªAppearance Care and Materialsº
in the Index.)
Your vehicle has a ªbasecoat/clearcoatº paint finish. The
clearcoat gives more depth and gloss to the colored basecoat.
Always use waxes and polishes that are non
-abrasive and
made for a basecoat/clearcoat paint finish.
NOTICE:
Machine compounding or aggressive polishing on
a basecoat/clearcoat paint finish may dull the
finish or leave swirl marks.
Foreign materials such as calcium chloride and other
salts, ice melting agents, road oil and tar, tree sap, bird
droppings, chemicals from industrial chimneys, etc., can
damage your vehicle's finish if they remain on painted
surfaces. Wash the vehicle as soon as possible. If
necessary, use non
-abrasive cleaners that are marked
safe for painted surfaces to remove foreign matter.Exterior painted surfaces are subject to aging, weather
and chemical fallout that can take their toll over a period
of years. You can help to keep the paint finish looking
new by keeping your vehicle garaged or covered
whenever possible.
Cleaning Your Convertible Top
Your convertible top should be cleaned often. If you use
an automatic car wash, use one with water jets and
hanging cloths. High pressure car washes may cause
water to enter your vehicle.
When you hand wash the top, do it in partial shade. Use
a mild soap, lukewarm water and a soft sponge. A
chamois or cloth may leave lint on the top, and a brush
can chafe the threads in the top fabric. Don't use
detergents, harsh cleaners, solvents or bleaching agents.
Wet the entire vehicle and wash the top evenly to avoid
spots or rings. Let the soap remain on the fabric for a
few minutes. When the top is really dirty, use a mild
foam
-type cleaner. Thoroughly rinse the entire vehicle,
then let the top dry in direct sunlight.

necessary. See ªWindshield Washer Fluidº in the Index
for further details.
