I
SERVICE
LTPWS
The amber SERVICE
LTPWS light comes on
whenever a LTPWS part is
not working properly. It
may also come on when
you’re going less than
25 mph (40 km/h) or in
stop-and-go traffic.
The light will
go out when the electronic receiver gets a
signal from each sensor.
Check the system by turning the ignition on. The light
should come on and then
go out. See your dealer if the
light stays on or doesn’t come on.
Here
are two situations that cause the SERVICE LTPWS
light to come on and stay on. Both of these situations are
normal and do qot indicate that anything is wrong with
your Corvette.
You turn the ignition on three times in a row for half
an hour without moving your Corvette. The light will
then come on every time you turn the ignition on
until you move your Corvette.
You run your Corvette three times for half an hour
while all four sensors
are missing. (All the sensors
would be missing, for example, if you put different
wheels on your Corvette without transferring the
sensors.)
If you would like to clear the SERVICE LTPWS light
from your driver information center permanently, see
your dealer.
If the light comes on and stays on, even when the
vehicle is driven, there may be a problem with LTPWS.
See your dealer.
Door Ajar Light
This red light comes on
when you open one of the
doors with the ignition on.
It stays on until you fully
close the door. Have your
vehicle serviced
if the light
comes on and stays on even
when the doors are fully
closed.

I
When the engine is not running, the voltmeter shows the
voltage output of your battery. When the engine is
running, it shows the voltage output
of the charging
system.
Readings between the shaded areas show the normal
operating range. The reading will change as the rate
of
charge changes (with engine speed, for example), but if
the voltmeter reads in either shaded area, and it stays
there, you may have a problem with the charging system,
Have it checked right away. Driving with the voltmeter
reading in a shaded area could drain your battery.

If you must drive a short distance with the voltmeter
reading in a shaded area, turn
off all your accessories,
including your comfort controls and audio systems.
For numeric gauge measurements, press the
GAUGES
button on the Trip Monitor until VOLT appears. The
number that appears next to the fuel gauge is the battery
voltage.

A computer monitors
operation
of your fuel,
ignition and emission
control systems. This amber
light should come on when
the ignition is on, but the
engine is not running, as a
check to show you it is
working.
If it does not come
on at all, have it fixed right away. If
it stays on, or it comes on while you are driving, the
computer is indicating that you have
a problem. You
should take your vehicle in for service soon.
NOTICE:
If you keep driving your vehicle with this light on,
after
a while the emission controls won’t work as
well, your fuel economy won’t be as good and your
engine may not
run as smoothly. This could lead to
costly repairs not covered by your warranty.
Engine Oil Pressure Gauge
-1
OIL
PRESS
PSI
The engine oil pressure gauge shows the engine
oil pressure in psi (pounds per square inch) or
kPa (kilopascals) when the engine is running. Oil
pressure should be
20 to 80 psi (140 to 550 Ea). It
may vary with engine speed, outside temperature and oil
viscosity, but readings above the shaded area show the
normal operating range. Readings in the shaded area tell
you that the engine is low on oil, or that you might have
some other oil problem. See “Engine Oil” in the Index.

Damage to your engine from neglected oil
problems can be costly and

warranty.
Engine Oil Temperature Gauge
LT1 LT5
This gauge shows your engine oil temperature. Oil
temperature may vary with the type
of driving you do
and weather conditions. If your gauge pointer moves
close to or into the shaded area and stays there, your oil
temperature is too high. Check the engine coolant
temperature and engine oil level. If your engine is too
hot, see “Engine Overheating” in the Index. Your
vehicle may need service; see your dealer.

For numeric gauge measurements, press the GAUGES
button on the Trip Monitor until OIL appears. The
number that appears next to the fuel gauge is the oil
temperature.
If LO appears, the temperature is below
32°F (OOC).
System Problems
If SYS flashes on the display near your fuel gauge,
there may be a problem with your Corvette’s electrical
system. If the amber SECURITY light flashes at the
same time, there
is a problem with your theft-deterrent
system. Have your vehicle checked by your dealer
if
SYS keeps appearing.
Gauge Markings
The analog gauges provide a quick visual reference to
the actual measurements of these gauges. However, you
must keep in mind that the gauges aren’t linear. This
means that the middle mark is not a temperature halfway
between the top and bottom temperatures on the gauge.
For your convenience, the following table gives the
exact reading for each mark.

Automatic transmission fluid temperature will be
displayed if you press the GAUGES button on the Trip
Monitor until AUTO appears. The number that appears
next to the fuel gauge is the automatic transmission fluid
temperature. If
LO appears, the temperature is below
32°F (0°C).

Downloaded from www.Manualslib.com manuals search engine It’s normal for the transmission fluid temperature to
vary, depending on the type of driving you do and
weather conditions. If you drive on long grades on a hot
day, the transmission fluid temperature will be higher
than normal driving on a cold day. If you drive your
Corvette at high speeds with a lot of stop-and-go or fast
accelerations, your transmission fluid temperature may
also be higher.
If the transmission fluid exceeds
280°F (138 “C), the
CHECK GAUGES light will come on and HI

will be displayed next to the transmission fluid
temperature when you toggle through the GAUGES
button. You should move the shift lever to DRIVE (D)
and continue driving at a slower, constant speed.
Monitor the transmission fluid temperature and allow
it
to cool to 180°F (82°C) to 200°F (93°C). Then, you
should check the transmission fluid level for a low fill or
overfill condition and bring your Corvette in for service
as soon as possible (see “Automatic Transmission Fluid”
in the Index). Also, check the engine coolant
temperature. If it’s too hot, see “Cooling System” in the
Index.
Check Gauges Light
This red light will come on
briefly when you are
starting the engine. If the
light comes on and stays on
while
you are driving, check
your gauges to see if they

high coolant temperature
high or low battery voltage

your engine and stays on,
your engine oil level may be
too low. You may need to
add oil. See “Engine Oil” in
the Index.
Engine Oil Life Monitor
The amber CHANGE OIL
light comes on for a few
seconds when you turn the
ignition
on. It will come on
and stay on when it’s time
to change your oil.
The monitor uses oil temperature and engine revolutions
to decide when the oil is nearly worn out. The light is
only a reminder, though.
You should change your oil at
the intervals recommended in your Maintenance
Schedule, even if the
CHANGE OIL light hasn’t come
on.
2-86

Downloaded from www.Manualslib.com manuals search engine Be sure to reset the monitor when your oil is changed,
even if the CHANGE OIL light didn’t come on. If you
don’t reset the monitor, it won’t work correctly. Follow
these steps:
1. Turn the key to RUN, but don’t start the engine.
2. Press ENG MET on the Trip Monitor. Then, within
five seconds, press it again.
3. Witbin five seconds, press and hold GAUGES on the
Trip’Monitor. The CHANGE OIL light should flash.
4. Hold the GAUGES button until the CHANGE OIL
light stops flashing and goes out. This should take
about ten seconds.
When the light goes out, the monitor is reset. If the
monitor doesn’t reset, turn the ignition
off, then try
again.
Service Ride Control Light
SERVICE
RIDE
CONTROL
If your vehicle is equipped
with Selective Ride Control,
this amber light should
come on for
a few seconds
when you start your vehicle.
If the light stays on or comes on while you’re driving,
there may be
a problem with your Selective Ride
Control system. You can still drive, but you should see
your dealer soon.
The Selective Ride Control system is designed to sense
vehicle speed in the first minute after the vehicle is
started. If the vehicle is not moved in that first minute,
the system records a fault. The SERVICE RIDE
CONTROL light comes on after three faults are
recorded. If the light comes on for this reason, move
your Corvette and the light should
go out.
