2005 CHEVROLET CORVETTE battery

If the vehicle has lost power, the convertible top can still
be raised by releasing pressure on the hydraulic
pump, located under the passenger’s side of the
tonneau cover, by using the following steps.
1. Open the tonneau cover.
2. Locate the pressure release bolt on the front side of
the hydraulic pump.3. Use the wrench, attached to the inboard side of the
hydraulic pump, and turn the pressure release bolt
counterclockwise one revolution, to relieve
pressure to the hydraulic pump. This will allow you
to manually raise the convertible top.
4. Then follow the steps under raising the manual
convertible top. See “Convertible Top (Manual)”
underConvertible Top (Manual) on page 2-57
orConvertible Top (Power) on page 2-64
When power is restored to the vehicle, the hydraulic bolt
must be tightened, by turning it clockwise. The power
convertible top button can then be used to lower or raise
the convertible top.
If the power convertible top is operated multiple times,
the engine should be running to prevent drain on
the vehicle’s battery. Under certain conditions, the Driver
Information Center (DIC) may display a message
regarding the power top. SeeDIC Warnings and
Messages on page 3-54for more information.

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 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.
Instrument Panel Brightness
The knob for this feature is
located on the left side of
the instrument panel.
Turn the knob clockwise to brighten the lights or
counterclockwise to dim them. During the day, this knob
will adjust the instrument panel brightness and at
night will adjust all interior lighting.Be sure not to have this knob turned all the way down
with the lamps on during the day. Your Driver
Information Center (DIC) may not be visible.
Courtesy Lamps
When any door or the hatch/trunk lid is opened, the
interior lamps will go on unless it is bright outside.
You can also turn the courtesy lamps on and off
by pressing the instrument panel brightness knob.
Entry/Exit Lighting
With entry lighting, the interior lamps will come on when
entering the vehicle. The interior lamps will come on
for about 20 seconds when the engine is off.
You can turn exit and entry lighting off by quickly turning
the courtesy lamps on and off.
Reading Lamps
Your inside rearview mirror includes two reading lamps.
The lamps will go on when a door is opened. When
the doors are closed, each lamp can be turned on
individually by pressing the switch for that lamp.

Battery Run-Down Protection
Your vehicle has a feature to help prevent you from
draining the battery in case the underhood lamp, vanity
mirror lamps, cargo lamps, reading lamps, console
or glove box lamps are accidentally left on. If you leave
any of these lamps on, they will automatically time-out
after about 20 minutes. To reset it, all of the above
lamps must be turned off or the ignition key on.
Head-Up Display (HUD)
{CAUTION:
If the HUD image is too bright, or too high in
your eld of view, it may take you more time to
see things you need to see when it is dark
outside. Be sure to keep the HUD image dim
and placed low in your eld of view.
If your vehicle is equipped with the Head-Up
Display (HUD), you can see some of the driver
information that appears on your instrument panel
cluster.The information may be displayed in English or metric
units and appears as an image focused out toward
the front of your vehicle. The HUD consists of the
following information:
Speedometer
Turn Signal Indicators
High-Beam Indicator Symbol
Tachometer
Oil and Temperature Gages
Shift Light (Performance SHIFT Light)
This light is used for performance driving to indicate
that the vehicle’s best performance level has
been reached to shift the transmission into the next
higher gear. The SHIFT light will display at an
engine speed of about 6,250 rpm, just prior
to reaching the engine fuel cut-off mode.

Accessory Power Outlets
The accessory power outlet can be used to connect
electrical equipment such as a cellular phone or
CB radio.
The accessory power outlet is located inside the center
console storage compartment, on the forward left side.
To use the outlet, remove the tethered cap. When not
using it, always cover the outlet with the protective cap.
Notice:Leaving electrical equipment on for
extended periods will drain the battery. Always turn
off electrical equipment when not in use and do
not plug in equipment that exceeds the maximum
amperage rating.
Certain electrical accessories may not be compatible
with the accessory power outlet and could result
in blown vehicle or adapter fuses. If you experience a
problem, see your dealer for additional information
on accessory power outlets.Notice:Adding any electrical equipment to your
vehicle may damage it or keep other components
from working as they should. The repairs would not
be covered by your warranty. Do not use equipment
exceeding maximum amperage rating. Check
with your dealer before adding electrical equipment.
When adding electrical equipment, be sure to follow
the installation instructions included with the equipment.
We recommend that you see a qualied technician or
your dealer for the proper installation of your equipment.
Notice:Improper use of the power outlet can
cause damage not covered by your warranty. Do not
hang any type of accessory or accessory bracket
from the plug because the power outlets are
designed for accessory power plugs only.
Electromagnetic Interference (EMI) can create a
disturbance and interfere with the keyless access
transmitter. EMI can be generated from devices such as
cell phones, cell phone chargers, or other items
plugged into the accessory outlet on the center console.
See “NO FOBS DETECTED” underDIC Warnings
and Messages on page 3-54.

Outlet Adjustment
Use the tab located on the air outlets to change the
direction of the airow.
Operation Tips

Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may
block the ow of air into your vehicle.
Use of non-GM approved hood deectors may
adversely affect the performance of the system.
Keep the area around the base of the instrument
panel console and air path under the seats clear
of objects to help circulate the air inside of
your vehicle more effectively.
Passenger Compartment Air Filter
The passenger compartment air lter removes certain
odor and particles from the air including pollen and dust
particles. Reductions in airow, which may occur
more often in dusty areas, indicate that the lter may
need to be replaced. SeeScheduled Maintenance
on page 6-4for information on how often to replace the
lter.Notice:Driving without a passenger compartment
air lter in place can cause water and small
particles, like paper and leaves, to be pulled into
your climate control system which may cause
damage to it. Make sure you always replace the old
lter with a new one.
The passenger compartment air lter is located on the
passenger side of the engine compartment near the
battery. SeeEngine Compartment Overview on
page 5-12.
To check or replace the air lter, do the following:
1. Disengage the passenger compartment air lter
housing cover retainer clips (1).
2. Remove the passenger compartment air lter
housing cover.

{CAUTION:
If the airbag readiness light ever comes on
when you have turned off the passenger’s
frontal airbag and side impact airbag
(if equipped), it means that something may
be wrong with the airbag system. The
passenger’s frontal airbag and side impact
airbag (if equipped) could inate even though
the switch is off. If this ever happens, do not
let anyone whom the national government has
identied as a member of a passenger airbag
risk group sit in the passenger’s position
(for example, do not secure a rear-facing child
restraint in your vehicle) until you have your
vehicle serviced. SeeAirbag Off Switch on
page 1-48.
Voltmeter Gage
The voltmeter shows the
voltage output of your
battery. When the engine
is running, it shows
the voltage output of the
charging system.
The reading will change as the rate of charge changes
(with engine speed, for example), but if the voltmeter
reads at 9 volts or below, your instrument panel cluster
and other systems may shut down. The Driver
Information Center (DIC) will read BATTERY VOLTAGE
LOW when your vehicle is at 10 volts or below. Have
it checked right away. Driving with the voltmeter reading
at 10 volts or below could drain your battery and
disable your vehicle.

Emissions Inspection and Maintenance
Programs
Some state/provincial and local governments have or
may begin programs to inspect the emission control
equipment on your vehicle. Failure to pass this
inspection could prevent you from getting a vehicle
registration.
Here are some things you need to know to help your
vehicle pass an inspection:
Your vehicle will not pass this inspection if the Check
Engine light is on or not working properly.
To perform a Check Engine light bulb check with the
keyless ignition, make sure the transmitter fob is in the
passenger compartment. SeeIgnition Positions on
page 2-21. Press the bottom of the ACC button on the
instrument panel and hold the button down for ve
seconds. The instrument panel, including the Check
Engine light, will light up and the ignition will be on, but
the engine will not start — if you press the bottom of
the ACC button only briey, less than ve seconds, the
accessory mode will be turned on, but not the ignition.
After the bulb check, be sure to press and release
the ACC button again to turn the ignition off and avoid
draining the vehicle’s battery.Your vehicle will not pass this inspection if the OBD
(on-board diagnostic) system determines that critical
emission control systems have not been completely
diagnosed by the system. The vehicle would be
considered not ready for inspection. This can happen if
you have recently replaced your battery or if your
battery has run down. The diagnostic system is
designed to evaluate critical emission control systems
during normal driving. This may take several days
of routine driving. If you have done this and your vehicle
still does not pass the inspection for lack of OBD
system readiness, your GM dealer can prepare the
vehicle for inspection.
