headlamp CHEVROLET CORVETTE 2000 5.G User Guide

4-31
Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go a little faster
than just idle. That is, push the accelerator slightly. This
uses less fuel for the heat that you get and it keeps the
battery charged. You will need a well
-charged battery
to restart the vehicle, and possibly for signaling later on
with your headlamps. Let the heater run for a while.
Then, shut the engine off and close the window almost
all the way to preserve the heat. Start the engine again
and repeat this only when you feel really uncomfortable
from the cold. But do it as little as possible. Preserve the
fuel as long as you can. To help keep warm, you can get
out of the vehicle and do some fairly vigorous exercises
every half hour or so until help comes.
Recreational Vehicle Towing
Your vehicle was not designed to be towed with all four
wheels on the ground. If your vehicle must be towed,
see ªTowing Your Vehicleº in the Index.
NOTICE:
Towing your vehicle with all four wheels on the
ground will damage drivetrain components.

6-10 Hood Release
NOTICE:
In order to avoid possible contact of the hood to
the headlamp doors, care should be taken in
raising the hood with the headlamps up, or shut
off the headlamps prior to opening the hood.
To open the hood, first pull
the handle located inside
the vehicle.
Then go to the side of the vehicle and pull up on the rear
edge of the hood, near the windshield.

6-25 Checking Coolant
The coolant surge tank is located in the engine
compartment behind the passenger's side headlamp.
CAUTION:
Turning the surge tank pressure cap when the
engine and radiator are hot can allow steam and
scalding liquids to blow out and burn you badly.
Never turn the surge tank pressure cap
-- even a
little
-- when the engine and radiator are hot.
The vehicle must be on a level surface. When your
engine is cold, the coolant level should be at the FULL
COLD mark. The FULL COLD mark is on the front of
the coolant surge tank. Don't overfill the surge tank.
Too much coolant can result in an overflow when the
fluid is hot.

Bulb Replacement
For the proper type of replacement bulb, see
ªReplacement Bulbsº in the Index.
For any bulb changing procedure not listed in this section,
contact your Chevrolet dealer's service department.
Halogen Bulbs
CAUTION:
Halogen bulbs have pressurized gas inside and
can burst if you drop or scratch the bulb. You or
others could be injured. Be sure to read and
follow the instructions on the bulb package.
Headlamps
1. The headlamp doors need to be halfway open. Turn
the headlamps on, then quickly back to the parking
lamps setting. You may have to do this a few times
to get the half
-open position.
You can also open the headlamp doors manually by
turning the adjuster counterclockwise.

6-34
2. Remove the screws using a Phillips screwdriver on
each side of the headlamp bezel.
3. Open the hood.
4. To remove the bezel, pull the sides slightly outward
and tilt the bezel forward. Pull the clip centered
above the lens outward. Be careful not to scratch
the paint.5. Reach behind the lamp and turn the bulb
counterclockwise to remove it. Don't touch the
halogen bulbs. The inner bulb is the high beam and
the outer bulb is the low beam.
6. Disconnect the desired bulb from the wiring harness.
7. Reverse the steps listed previously with a new bulb.

6-49 Wheel Alignment and Tire Balance
The wheels on your vehicle were aligned and balanced
carefully at the factory to give you the longest tire life
and best overall performance.
Scheduled wheel alignment and wheel balancing are not
needed. However, if you notice unusual tire wear or
your vehicle pulling one way or the other, the alignment
may need to be reset. If you notice your vehicle
vibrating when driving on a smooth road, your wheels
may need to be rebalanced.
Wheel Replacement
Replace any wheel that is bent, cracked, or badly rusted
or corroded. If wheel nuts keep coming loose, the wheel,
wheel bolts and wheel nuts should be replaced. If the
wheel leaks air, replace it (except some aluminum
wheels, which can sometimes be repaired). See your
dealer if any of these conditions exist.
Your dealer will know the kind of wheel you need.
Each new wheel should have the same load
-carrying
capacity, diameter, width, offset and be mounted the
same way as the one it replaces.
If you need to replace any of your wheels, wheel bolts
or wheel nuts, replace them only with new GM original
equipment parts. This way, you will be sure to have the
right wheel, wheel bolts and wheel nuts for your vehicle.
CAUTION:
Using the wrong replacement wheels, wheel bolts
or wheel nuts on your vehicle can be dangerous.
It could affect the braking and handling of your
vehicle, make your tires lose air and make you
lose control. You could have a collision in which
you or others could be injured. Always use the
correct wheel, wheel bolts and wheel nuts
for replacement.
NOTICE:
The wrong wheel can also cause problems with
bearing life, brake cooling, speedometer or
odometer calibration, headlamp aim, bumper
height, vehicle ground clearance and tire
clearance to the body and chassis.

6-67
NOTICE:
When using the accessory power plug:

DO NOT splice wires directly into the
vehicle electrical wire harness. If done
incorrectly, splicing may cause damage to
your electrical system and would not be
covered by the vehicle's warranty.

The maximum load of any electrical
equipment should not exceed 15 amps.

Be sure to turn off any electrical equipment
when not in use. Leaving electrical
equipment on for extended periods of time
can drain your battery.

DO NOT use this plug if the electrical
equipment requires frequent connecting
and disconnecting. This may cause
excessive wear on the accessory power plug
and damage your electrical system and
the damage would not be covered by
your warranty.
Headlamps
The headlamp wiring is protected by a circuit breaker.
An electrical overload will cause the lamps to go on and
off, or in some cases to remain off. If this happens, have
your headlamp wiring checked right away.
Windshield Wipers
The windshield wiper motor is protected by a fuse and
an internal circuit breaker. If the motor overheats due to
heavy snow, etc., the wiper will stop until the motor
cools. If the overload is caused by some electrical
problem and not snow, etc., be sure to get it fixed.
Power Windows and Other Power Options
Circuit breakers protect the power seats and other power
accessories. When the current load is too heavy, the
circuit breaker opens and closes, protecting the circuit
until the problem is fixed or goes away.
