2003 CHEVROLET CORVETTE fuel pressure

NEUTRAL:Use this position when you start or idle
your engine. Your shift lever is in NEUTRAL when it is
centered in the shift pattern, not in any gear.
REVERSE (R):To back up, press down the clutch
pedal and shift into REVERSE (R). Just apply pressure
to get the lever past FIFTH (5) and SIXTH (6) into
REVERSE (R). Let up on the clutch pedal slowly while
pressing the accelerator pedal.
Your six-speed manual transmission has a feature that
allows you to safely shift into REVERSE (R) while
the vehicle is rolling (at less than 3 mph (5 km/h)). You
will be locked out if you try to shift into REVERSE (R)
while your vehicle is moving faster than 3 mph (5 km/h).
If you have turned your ignition off and wish to park
your vehicle in REVERSE (R), you will have to move the
shift lever quickly to the right, and immediately forward
into gear.Shift Speeds (Manual Transmission)
{CAUTION:
If you skip a gear when you downshift, you
could lose control of your vehicle. You could
injure yourself or others. Don't shift down
more than one gear at a time when you
downshift.
This chart shows when to shift to the next higher gear
for the best fuel economy.

Security Light
This light comes on to
remind you to arm your
theft-deterrent system. If it
comes on and stays on
when your ignition is
on, there may be a
problem with your
theft-deterrent system.
See
Theft-Deterrent System on page 2-16andPASS-Keyžon page 2-17.
Check Gages Warning Light
This light will come on
brie¯y when you are
starting the engine. If the
light comes on and
stays on while you are
driving, check your gages
to see if they are in the
warning areas.This light can come on for the following reasons:
·Low Oil Pressure
·High Coolant Temperature
·High or Low Battery Voltage
·Low Fuel Level
Fuel Gage
Your fuel gage tells you
about how much fuel you
have left when the
ignition is on.
When the needle approaches the red zone, RESERVE
FUEL will appear on the Driver Information Center (DIC)
display. When the needle approaches the E, LOW
FUEL will appear on the display. At this time, you still
have a little fuel left, but you should get more soon.

The following buttons are located on the DIC control
panel which is located to the right of the instrument
panel cluster.1 FUEL:Press this button to display fuel information
such as fuel economy and range.
2 GAGES:Press this button to display gage information
like oil pressure and temperature, coolant temperature,
automatic transmission ¯uid temperature, battery
voltage and front/rear tire pressures.
3 TRIP:Press this button to display your total and trip
miles, the elapsed time function, your average speed
and the engine oil life.

Press FUEL again to display instantaneous fuel
economy, such as:
·INST. 20.1 MPG or
·INST. 5.3 L/100 km
Press FUEL again to display the range, such as:
·RANGE 20 MI or

The range calculates the remaining distance you can
drive without refueling. It's based on fuel economy and
the fuel remaining in the tank.
If the range is lower than 30 miles (48 km), the display
will read RANGE LOW.
The fuel economy data used to determine fuel range is
an average of recent driving conditions. As your
driving conditions change, this data is gradually updated.
Resetting the fuel range causes the fuel economy
data to be updated immediately. Press RESET to reset
the fuel range.

Traction Control System and the Active Handling
System will also be disabled. The Driver Information
Center will scroll three messages: SERVICE ABS,
SERVICE TRACTION SYS and SERVICE ACTIVE
HNDLG, and the instrument cluster car icon will

unlocking of the steering column does not work properly,
have the vehicle towed to a dealer for service.
PULL KEY ± WAIT 10 SEC (Manual Transmission
Only):If this message comes on, the steering column
lock system has detected a problem while disengaging
the steering column lock. This message may occur when
the ignition key is removed and reinserted before the
steering column lock system fully locks or unlocks
the steering column. To acknowledge that you have read
this message, and to clear it from the display, remove
the ignition key and wait 10 seconds before reinserting
the key into the ignition. If you attempt to operate
your vehicle without removing the key for 10 seconds,
the vehicle's fuel system will shut off when you
reach 1.5 mph (2.4 km/h). If the message stays on afterremoving the key and waiting 10 seconds, have your
vehicle taken to an authorized dealer as soon as
possible for diagnosis and repair.
LOW OIL PRESSURE:You will hear four chimes and
the CHECK GAGES telltale will come on when this
message is displayed. To acknowledge the warning,
press the RESET button. After you press the RESET
button, a message will be displayed and you will hear a
chime every minute until the vehicle is serviced. If
you do not press RESET, the message will remain on
the digital display until the vehicle is serviced.
Low oil pressure may be the result of a combination of
low oil level and abrupt changes in the vehicle's
direction. When this warning is displayed, you should
not operate the engine at high rpm or make fast abrupt
moves. As soon as possible, you should check the
oil level. See
Engine Oil on page 5-13.
LOW OIL LEVEL:Press RESET to acknowledge that
you have read the message and to remove it from
the display. The message will reappear every
10 minutes until this condition changes. Once the
vehicle senses a temperature change in the engine oil,
the light will remain off.
You will hear two chimes when this message is
displayed. If this message appears after starting your
engine, your engine oil level may be too low. You
may need to add oil. See
Engine Overheating on
page 5-26.

Once you are moving on the freeway, make certain you
allow a reasonable following distance.
Expect to move slightly slower at night.
When you want to leave the freeway, move to the
proper lane well in advance. If you miss your exit, do
not, under any circumstances, stop and back up. Drive
on to the next exit.
The exit ramp can be curved, sometimes quite sharply.
The exit speed is usually posted. Reduce your speed
according to your speedometer, not to your sense
of motion. After driving for any distance at higher
speeds, you may tend to think you are going slower
than you actually are.
Before Leaving on a Long Trip
Make sure you're ready. Try to be well rested. If you
must start when you're not fresh Ð such as after a day's
work Ð don't plan to make too many miles that ®rst
part of the journey. Wear comfortable clothing and shoes
you can easily drive in.Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it's ready to go. If it needs
service, have it done before starting out. Of course,
you'll ®nd experienced and able service experts in GM
dealerships all across North America. They'll be
ready and willing to help if you need it.
Here are some things you can check before a trip:
·Windshield Washer Fluid:Is the reservoir full? Are
all windows clean inside and outside?
·Wiper Blades:Are they in good shape?
·Fuel, Engine Oil, Other Fluids:Have you checked
all levels?
·Lamps:Are they all working? Are the lenses clean?
·Tires:They are vitally important to a safe,
trouble-free trip. Is the tread good enough for
long-distance driving? Are the tires all in¯ated to the
recommended pressure?
·Weather Forecasts:What's the weather outlook
along your route? Should you delay your trip a
short time to avoid a major storm system?
·Maps:Do you have up-to-date maps?
