2-65 Storing the Roof Panel
CAUTION:
If the roof panel is not stored properly, it could be
thrown about the vehicle in a crash or sudden
maneuver. People in the vehicle could be injured.
Whenever you store the roof panel in the vehicle,
always be sure that it is stored securely in the
rear area using the storage pins.
NOTICE:
To avoid damage to the roof panel, paint and
weatherstripping, do not drop or rest it on its
edges. Place the roof panel in the egg
-shaped
stowage receivers after removing it from
the vehicle.
1. Turn the roof panel so that the rear edge of the panel
is facing the storage area. The locating pins (at the
rear of the panel) should point toward the
egg
-shaped stowage receivers on the floor of the
center compartment.
2. Push the panel forward until the pins bottom out in
the receivers.
3. There are two spring-loaded storage pins on the rear
wall of the storage compartment (A). These storage
pins go into the slots on each side of the roof
panel (B).

4. Gently lower the roof panel onto the carpet ledge.
Then, pull each release rearward and upward to place
the storage pins into the holes of the roof panel.
5. Gently lift and lower the roof panel to be sure it is
locked into place.
Installing the Roof Panel
CAUTION:
An improperly attached roof panel may fall into
or fly off the vehicle. You or others could be
injured. After installing the roof panel, always
check that it is firmly attached by pushing up on
the underside of the panel. Check now and then
to be sure the roof panel is firmly in place.
NOTICE:
To avoid damage to the roof panel, paint and
weatherstripping, do not drop or rest it on
its edges.

1. Check to be sure that the front handles and rear latch
on the ceiling are in their opened positions before
attempting to install the roof panel.
2. If the roof panel is stored in the rear area, grasp it
with your right hand at the middle edge near the
seatbacks, and with your left hand at the middle of
the edge closest to you. Reverse the steps described
previously under ªStoring the Roof Panel.º
3. Remove the roof panel from the
storage compartment.
4. In most cases, it is easier to install the removable
roof with two people rather than one. Place the roof
panel over the vehicle.
5. Position the rear edge of the roof panel to the
weatherstrip on the back of the roof opening (A). Then
align the pins at the rear of the roof panel weatherstrip
with the receiving cup in the body weatherstrip (B).
Gently lower the front edge of the roof panel to the
front of the body opening (C).
6. Rotate the front handles toward the side doors to the
closed position.
7. Hook the rear latch by pushing the lever up to the
locked position.
8. Grasp and tug the roof panel up and down and
side
-to-side to make sure the roof panel is
securely installed.

When adjusting the temperature, start with a driver-set
temperature of 73
F (23
C) until you determine your
comfort zone. If you choose 60
F (16
C), the
system will remain at maximum cooling and will not
automatically adjust fan speed or air delivery. If you
choose 90
F (32
C), the system will remain at
maximum heating and will not automatically adjust fan
speed or air delivery. Choosing either maximum setting
will not cause the system to heat or cool any faster.
Turning the knob past either maximum setting has no
effect on the operation of the system.
Passenger Temperature Offset
The PASSENGER knob changes the temperature on the
passenger's side of the vehicle. When the knob is in the
12 o'clock position, the passenger's temperature is the
same as the driver's. Turn the knob clockwise for
warmer air on the passenger's side, counterclockwise for
cooler air. If the driver
-set temperature is set at 60
F
(16
C) or 90
F (32
C), turning the passenger knob
has no effect because the system is locked at a
maximum setting.Automatic Operation
Press the AUTO button to place the entire system in the
automatic mode. After a five
-second display of the
current settings, only the word AUTO and the outside
temperature will be shown on the digital display. The
system will operate to achieve your comfort set
temperature as quickly as possible. If you have set the
driver temperature at 60
F (16
C) or 90
F (32
C),
the system will not operate automatically until a
different temperature is selected. The AUTO control
system works best with the windows up and the
removable roof installed or the convertible top up.
A Typical Cold Weather Example:
Your vehicle has been parked outside overnight in cold
weather (below 32
F/ 0
C) and you have set the driver
temperature at 73
F (23
C) and have selected the
AUTO mode. The system will automatically adjust the
temperature output to maximum heating. The fan will
start at a low speed. This is to avoid blowing cold air
into the vehicle. The length of the delay depends on the
amount of time since the engine was last started, the
outside temperature and the engine coolant temperature.
As the coolant warms up, the fan speed will gradually
increase. Air will flow to the floor with some air to
the windshield to prevent fogging under most
normal conditions.

Cleaning the Outside of the
Windshield and Wiper Blades
If the windshield is not clear after using the windshield
washer, or if the wiper blade chatters when running,
wax, sap or other material may be on the blade
or windshield.
Clean the outside of the windshield with GM
Windshield Cleaner, Bon Ami

Powder (non-scratching
glass cleaning powder), GM Part No. 1050011. The
windshield is clean if beads do not form when you rinse
it with water.
If you use a glass treatment or conditioner containing
ethyl alcohol or ethyl sulfate on your glass, be sure to
remove the acrylic roof panel, if so equipped. These
products may damage the panel.
Grime from the windshield will stick to the wiper blades
and affect their performance. Clean the blade by wiping
vigorously with a cloth soaked in full
-strength
windshield washer solvent. Then rinse the blade
with water.
Check the wiper blades and clean them as necessary;
replace blades that look worn.
Weatherstrips
Silicone grease on weatherstrips will make them last
longer, seal better, and not stick or squeak. Apply
silicone grease with a clean cloth at least every six
months. During very cold, damp weather more frequent
application may be required. (See ªRecommended
Fluids and Lubricantsº in the Index.)
Cleaning a Removable Roof Panel
Special care is necessary when cleaning, removing
and/or storing the roof panel.

Flush with water to remove dust and dirt, then dry
the panel.

Clean the panel with GM Glass Cleaner. Leave the
cleaner on the panel for one minute, then wipe the
panel with a soft, lint
-free cloth.

Don't use abrasive cleaning materials.

yellowblue
6-60
If water drops are frequently allowed to dry on the roof
panel, impurities in the water will adhere to the top.
These impurities may etch or mar the finish. When the
panel gets wet, you should dry it off.
NOTICE:
Do not use a glass treatment or conditioner
containing ethyl alcohol or ethyl sulfate on the
roof panel. These products may damage
the panel.
Cleaning the Outside of Your Vehicle
The paint finish on your vehicle provides beauty, depth
of color, gloss retention and durability.
Washing Your Vehicle
The best way to preserve your vehicle's finish is to keep it
clean by washing it often with lukewarm or cold water.
Don't wash your vehicle in the direct rays of the sun.
Use a car washing soap. Don't use strong soaps or
chemical detergents. Be sure to rinse the vehicle well,
removing all soap residue completely. You can get
GM
-approved cleaning products from your dealer. (SeeªAppearance Care and Materialsº in the Index.) Don't
use cleaning agents that are petroleum based, or that
contain acid or abrasives. All cleaning agents should be
flushed promptly and not allowed to dry on the surface,
or they could stain. Dry the finish with a soft, clean
chamois or an all
-cotton towel to avoid surface
scratches and water spotting.
High pressure car washes may cause water to enter
your vehicle.
NOTICE:
Conveyor systems on some automatic car washes
may damage a Corvette. They may not have
enough clearance for the undercarriage or for the
wide rear tires.
Check with the manager before using a car wash.
Cleaning Exterior Lamps/Lenses
Use lukewarm or cold water, a soft cloth and a car
washing soap to clean exterior lamps and lenses. Follow
instructions under ªWashing Your Vehicle.º
