6-52 Tire Chains
NOTICE:
Don't use tire chains. They can damage your
vehicle because there's not enough clearance.
Use another type of traction device only if its
manufacturer recommends it for use on your
vehicle and tire size combination and road
conditions. Follow that manufacturer's
instructions. To help avoid damage to your
vehicle, drive slowly, readjust or remove the
device if it's contacting your vehicle, and don't
spin your wheels.
If you do find traction devices that will fit, install
them on the rear tires.
Lifting Your Corvette
CAUTION:
Lifting a vehicle can cause an injury. The vehicle
can slip off the jack and roll over you or other
people. You and they could be badly injured.
Find a level place to lift your vehicle. To help
prevent the vehicle from moving:
1. Set the parking brake firmly.
2. Put an automatic transmission shift
lever in PARK (P), or shift a manual
transmission to FIRST (1) or
REVERSE (R).
3. Turn off the engine.
To be even more certain the vehicle won't move,
you can put blocks in front of and behind
the wheels.

Magnesium Wheel Finish
NOTICE:
Improper paint repair or refinishing can cause
corrosion damage to a magnesium wheel. See
your dealer if a magnesium wheel needs paint
repair or refinishing.
Underbody Maintenance
Chemicals used for ice and snow removal and dust
control can collect on the underbody. If these are not
removed, accelerated corrosion (rust) can occur on the
underbody parts such as fuel lines, frame, floor pan and
exhaust system even though they have
corrosion protection.
At least every spring, flush these materials from the
underbody with plain water. Clean any areas where mud
and other debris can collect. Dirt packed in closed areas
of the frame should be loosened before being flushed.
Your dealer or an underbody car washing system can do
this for you.
Fiberglass Springs
NOTICE:
Don't use corrosive or acidic cleaning agents,
engine degreasers, aluminum cleaning agents or
other harsh solvents to clean fiberglass springs;
they'll damage the springs.
Chemical Paint Spotting
Some weather and atmospheric conditions can create a
chemical fallout. Airborne pollutants can fall upon and
attack painted surfaces on your vehicle. This damage
can take two forms: blotchy, ringlet
-shaped
discolorations, and small irregular dark spots etched into
the paint surface.
Although no defect in the paint job causes this,
Chevrolet will repair, at no charge to the owner, the
surfaces of new vehicles damaged by this fallout
condition within 12 months or 12,000 miles (20 000 km)
of purchase, whichever occurs first.

Vehicle Identification Number (VIN)
This is the legal identifier for your vehicle. It appears on
a plate in the front corner of the instrument panel, on the
driver's side. You can see it if you look through the
windshield from outside your vehicle. The VIN also
appears on the Vehicle Certification and Service Parts
labels and the certificates of title and registration.
Engine Identification
The 8th character in your VIN is the engine code. This
code will help you identify your engine, specifications
and replacement parts.
Service Parts Identification Label
You'll find this label located inside the glovebox. It's
very helpful if you ever need to order parts. On this
label is:

your VIN,

the model designation,

paint information and

a list of all production options and
special equipment.
Be sure that this label is not removed from the vehicle.

Scheduled Maintenance

7-6Engine Oil Scheduled Maintenance
Change engine oil as indicated by the Engine Oil Life
Monitor (or every 12 months, whichever occurs
first). Reset the monitor. The monitor will show you
when to change the oil
-- usually between 3,000 miles
(5 000 km) and 10,000 miles (16 000 km) since your
last oil change. Under severe conditions, the indicator
may come on before 3,000 miles (5 000 km). Never
drive your vehicle more than 10,000 miles (16 000 km)
or 12 months without an oil change. Use engine oil
meeting the GM Standard GM4718M.The Engine Oil Life Monitor won't detect dust in the
oil. So if you drive in a dusty area, be sure to change
your oil every 3,000 miles (5 000 km) or sooner if the
CHANGE OIL SOON message comes on. Remember to
reset the Oil Life Monitor when the oil has been
changed. See ªEngine Oil Life Monitorº in the Index for
more information on resetting the monitor.
