2010 CHEVROLET CORVETTE headlamp

Driving at Night
Night driving is more dangerous than day driving
because some drivers are likely to be impaired —by
alcohol or drugs, with night vision problems, or by
fatigue.
Night driving tips include:
.Drive defensively.
.Do not drink and drive.
.Reduce headlamp glare by adjusting the inside
rearview mirror.
.Slow down and keep more space between you and
other vehicles because headlamps can only light
up so much road ahead.
.Watch for animals.
.When tired, pull off the road.
.Do not wear sunglasses.
.Avoid staring directly into approaching headlamps.
.Keep the windshield and all glass on your vehicle
clean —inside and out.
.Keep your eyes moving, especially during turns
or curves.
No one can see as well at night as in the daytime.
But, as we get older, these differences increase.
A 50-year-old driver might need at least twice as much
light to see the same thing at night as a 20-year-old.
Driving in Rain and on Wet Roads
Rain and wet roads can reduce vehicle traction and
affect your ability to stop and accelerate. Always drive
slower in these types of driving conditions and avoid
driving through large puddles and deep‐standing or
flowing water.
{WARNING:
Wet brakes can cause crashes. They might not
work as well in a quick stop and could cause
pulling to one side. You could lose control of
the vehicle.
After driving through a large puddle of water or a
car/vehicle wash, lightly apply the brake pedal
until the brakes work normally.
Flowing or rushing water creates strong forces.
Driving through flowing water could cause your
vehicle to be carried away. If this happens, you
and other vehicle occupants could drown. Do not
ignore police warnings and be very cautious about
trying to drive through flowing water.

WARNING: (Continued)
For more information about carbon monoxide, see
Engine Exhaust on page 3‑37.
Snow can trap exhaust gases under your vehicle.
This can cause deadly CO (carbon monoxide) gas
to get inside. CO could overcome you and kill you.
You cannot see it or smell it, so you might not
know it is in your vehicle. Clear away snow from
around the base of your vehicle, especially any
that is blocking the exhaust.
Run the engine for short periods only as needed to
keep warm, but be careful.
To save fuel, run the engine for only short periods as
needed to warm the vehicle and then shut the engine
off and close the window most of the way to save heat.
Repeat this until help arrives but only when you feel
really uncomfortable from the cold. Moving about to
keep warm also helps.
If it takes some time for help to arrive, now and then
when you run the engine, push the accelerator pedal
slightly so the engine runs faster than the idle speed.
This keeps the battery charged to restart the vehicle
and to signal for help with the headlamps. Do this as
little as possible to save fuel.
If Your Vehicle is Stuck in Sand,
Mud, Ice, or Snow
Slowly and cautiously spin the wheels to free the
vehicle when stuck in sand, mud, ice, or snow.
See Rocking Your Vehicle to Get It Out on page 5‑28.
If the vehicle has a traction system, it can often help
to free a stuck vehicle. Refer to the vehicle's traction
system in the Index. If stuck too severely for the traction
system to free the vehicle, turn the traction system off
and use the rocking method.
{WARNING:
If the vehicle's tires spin at high speed, they
can explode, and you or others could be injured.
The vehicle can overheat, causing an engine
compartment fire or other damage. Spin the
wheels as little as possible and avoid going above
55 km/h (35 mph) as shown on the speedometer.
For information about using tire chains on the vehicle,
see Tire Chains on page 6‑84.

Rear Axle
When to Check Lubricant
It is not necessary to regularly check rear axle fluid
unless you suspect there is a leak or you hear an
unusual noise. A fluid loss could indicate a problem.
Have it inspected and repaired.
How to Check Lubricant
To get an accurate reading, the vehicle should be on a
level surface. If the level is below the bottom of the filler plug hole,
you will need to add some lubricant. Add enough
lubricant to raise the level to the bottom of the filler
plug hole.
What to Use
To add lubricant when the level is low, use Dexron LS
Gear Oil 75W-90 (GM Part No. US. 88862624, in
Canada 88862625) meeting GM Specification 9986290.
To completely refill after draining, see
Recommended
Fluids and Lubricants
on page 7‑10. Then fill to the
bottom of the filler plug hole with the Synthetic Gear
Lubricant.
Headlamp Aiming
Headlamp aim has been preset at the factory and
should need no further adjustment.
However, if your vehicle is damaged in a crash, the
headlamp aim may be affected. Aim adjustment to the
low-beam headlamps may be necessary if oncoming
drivers flash their high-beam headlamps at you (for
vertical aim).
If the headlamps need to be re-aimed, it is
recommended that you take the vehicle to your dealer/
retailer for service.

Bulb Replacement
For the proper type of replacement bulbs, see
Replacement Bulbs on page 6‑58.
For any bulb changing procedure not listed in this
section, contact your dealer/retailer.
High Intensity Discharge (HID)
Lighting
{WARNING:
The low beam high intensity discharge lighting
system operates at a very high voltage. If you try
to service any of the system components, you
could be seriously injured. Have your dealer/
retailer or a qualified technician service them.
The vehicle may have HID headlamps. After an HID
headlamp bulb has been replaced, you may notice
that the beam is a slightly different shade than it was
originally. This is normal.
Halogen Bulbs
{WARNING:
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, Front Turn Signal, and
Parking Lamps
A. High-beam Headlamp
B. Low-beam Headlamp
C. Front Parking/Turn Signal/Daytime Running Lamp (DRL)
6-56

If the low-beam headlamp needs to be replaced, see
your dealer/retailer. See High Intensity Discharge (HID)
Lighting
on page 6‑56for more information.
To replace a high-beam or front parking/turn signal/
DRL bulb: 1. Turn the wheel to allow access to the wheel well.
2. Remove the three outer fasteners to move the access panel back. 3. Remove the outer cover to expose the high-beam
headlamp bulb socket.
4. Remove the headlamp
bulb by releasing the
outer tabs from the
socket.
5. Remove the front parking/turn signal bulb by turning the bulb socket counterclockwise.
6. Replace the high-beam headlamp bulb with a new bulb and reattach to the bulb socket.
Replace the front parking/turn signal bulb by
turning the bulb socket clockwise.
7. Reverse the Steps 2 through 4 to reinstall.

Taillamps, Turn Signal, and
Stoplamps
To replace a stoplamp, taillamp/turn signal bulb: 1. Remove the screw from the top of the lamp assembly.
2. Tilt the lamp assembly toward you.
3. Turn the bulb socket one-quarter turn counterclockwise and pull it out. 4. Pull the bulb straight out to remove it from the
socket.
5. Push the new bulb in the bulb socket until it snaps into place.
6. Reinstall the lamp assembly by first lining up the tabs on the bottom of the lamp assembly with the
tabs in the vehicle, then slide it in.
7. Replace the screw at the top of the lamp assembly.
