2007 CHEVROLET CORVETTE headlamp

When it is dark enough outside, the front turn
signal lamps will turn off and normal low-beam
headlamps will turn on.
When it is bright enough outside, the regular
lamps will go off, and the front turn signal lamps
will take over. If you start your vehicle in a
dark garage, the automatic headlamp system
will come on immediately. Once you leave
the garage, it will take approximately one minute
for the automatic headlamp system to change
to DRL if it is light outside. During that delay, the
instrument panel cluster may not be as bright
as usual. Make sure your instrument panel
brightness knob is in the full bright position.
SeeInstrument Panel Brightness on page 172for
more information.
If it is dark enough outside and the exterior lamp
control is off, a HEADLAMPS SUGGESTED
message will display on the Driver’s Information
Center (DIC). This message informs the driver that
turning on the exterior lamps is recommended.
SeeDIC Warnings and Messages on page 214.Turning the exterior lamp control to off a
second time, or turning on the headlamps will
remove the HEADLAMPS SUGGESTED message
in the DIC. If the parking lamps or the fog lamps
were turned on instead, the HEADLAMPS
SUGGESTED message will continue to be
displayed.
As with any vehicle, you should turn on the
regular headlamp system when you need it.
To turn off the DRL, turn the exterior lamp control
to the off position or shift into PARK (P). The
DRL will stay off until the control is toggled again
or the vehicle is shifted out of PARK (P).
This procedure applies only to vehicles rst sold
in the United States.

Fog Lamps
Use fog lamps for better vision in foggy or misty
conditions.
The fog lamps control is located on the
multifunction lever next to the exterior lamp
control.
-(Fog Lamps):Turning the band to this
position will turn the fog lamps on.
When you turn the fog lamps on, the fog lamp
light will appear on the instrument panel cluster
to indicate that the fog lamps and the parking
lamps are on.
If you turn the high-beam headlamps on, the
fog lamps will turn off. They will turn on again
when you switch to low-beam headlamps.
The ignition must be on for the fog lamps to
operate.
Some localities have laws that require the
headlamps to be on along with the fog lamps.
Twilight Sentinel®
Twilight Sentinel®can turn your lamps on and off
for you. A light sensor on top of the instrument
panel makes the Twilight Sentinel
®work, so
be sure it is not covered.
With Twilight Sentinel
®, you will see the following
happen:
When it is dark enough outside, the front
turn signal lamps (DRL) will go off, and
the headlamps and parking lamps will come
on. The other lamps that come on with
headlamps will also come on.
When it is bright enough outside, the
headlamps will go off, and the front turn signal
lamps (DRL) will come on, as long as the
exterior lamp switch is in the AUTO position.
If you start your vehicle in a dark garage, the
automatic headlamp system will come on
immediately. Once you leave the garage, it will
take about one minute for the automatic headlamp
system to change to DRL if it is light outside. During
that delay, your instrument panel cluster may not
be as bright as usual. Make sure your instrument
panel brightness control is in full bright position.
SeeInstrument Panel Brightness on page 172.

you turn the control band to off again.
Twilight Sentinel
®also provides exterior
illumination as you leave the vehicle. If Twilight
Sentinel
®has turned on the lamps when you turn
off the ignition, your lamps will remain on until:
The exterior lamp switch is moved from
off to the parking lamp position, or
A delay time that you select has elapsed.
See “Personal Options” underDIC Vehicle
Personalization on page 234to select the
delay time that you want. You can also select
no delay time.
If you turn off the ignition with the exterior lamp
switch in the parking lamp or headlamp position, the
Twilight Sentinel
®delay will not occur. The lamps
will turn off as soon as the switch is turned off.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Exterior Lighting Battery Saver
If the manual parking lamps or headlamps have
been left on, the exterior lamps will turn off as soon
as the ignition is turned off or Retained Accessory
Power (RAP) is active. This protects against
draining the battery in case you have accidentally
left the headlamps or parking lamps on. The battery
saver does not work if the headlamps are turned on
after the ignition switch is turned to off.
If you need to leave the lamps on, use the exterior
lamp control to turn the lamps back on.

Vehicles with the Z51 performance package
have greaseable outer ends on both of the rear
toe-links. Under normal use, lubrication should
be performed as described in the maintenance
schedule. SeeScheduled Maintenance on
page 433andRecommended Fluids and
Lubricants on page 443. If you use the vehicle
for racing, lubrication should be performed at the
end of each racing day. See your dealer/retailer
for lubrication and make sure any needed
repairs are made at once. Proper procedures for
performing these services can be found in the
service manual. SeeService Publications
Ordering Information on page 468.Driving at Night
Night driving is more dangerous than day driving.
One reason is that some drivers are likely to
be impaired — by alcohol or drugs, with night
vision problems, or by fatigue.
Here are some tips on night driving.
Drive defensively.
Do not drink and drive.
Adjust the inside rearview mirror to reduce
the glare from headlamps behind you.
Since you cannot see as well, slow down
and keep more space between you and
other vehicles.
Slow down, especially on higher speed roads.
Your vehicle’s headlamps can light up only so
much road ahead.
In remote areas, watch for animals.
If you are tired, pull off the road in a safe
place and rest.
