2007 CHEVROLET CORVETTE warning light

Engine Coolant Temperature Gage
This gage shows the engine coolant temperature.
If the gage pointer moves into the shaded area,
your engine is too hot.
This means that your engine coolant has
overheated. If you have been operating your
vehicle under normal driving conditions, you should
pull off the road, stop your vehicle and turn off
the engine as soon as possible.
SeeEngine Overheating on page 350for more
information.
Tire Pressure Light
This light will come on
briey when you turn
the ignition on.
This light will also come on when one or more of
your tires are signicantly underinated.
A LOW TIRE PRESSURE message in the Driver
Information Center (DIC) will accompany the light,
seeDIC Warnings and Messages on page 214
Stop and check your tires as soon as it is safe to do
so. If underinated, inate to the proper pressure.
SeeTires on page 378for more information.
This light will ash for about 60 seconds and
then turn on solid if a problem is detected with
the Tire Pressure Monitor system.
SeeTire Pressure Monitor System on page 389

Here are ve things that some owners ask about.
All these things are normal and do not indicate
that anything is wrong with the fuel gage.
At the gas station, the gas pump shuts off
before the gage reads the full symbol.
It takes more (or less) fuel to ll up than the
gage reads. For example, the gage reads
half full, but it took more (or less) than half
of the tank’s capacity to t it.
The gage pointer may move while cornering,
braking or speeding up.
The gage may not indicate the tank is empty
when the ignition is turned off.
The gage reading may change slightly within
the rst several minutes after starting the
vehicle.
SeeDIC Controls and Displays on page 208for
more information.
Driver Information Center (DIC)
The Driver Information Center (DIC) gives you
the status of many of your vehicle’s systems.
It is also used to display driver personalization
features and warning/status messages. The
DIC display is located on the instrument panel
cluster below the speedometer and tachometer,
directly above the steering column. The DIC
buttons are located on the instrument panel,
to the right of the instrument panel cluster.
The DIC comes on when the ignition is turned on.
After displaying CORVETTE BY CHEVROLET,
the DIC will display the current driver and
the information that was last displayed before
the engine was turned off.

270°F (132°C) or rises rapidly. The transmission
may shift gears or apply the torque converter
clutch to reduce the uid temperature. Driving
aggressively or driving on long hills can cause the
transmission uid temperature to be higher than
normal. If this message appears, you may continue
to drive at a slower speed. Monitor the transmission
uid temperature and allow it to cool to at least
230°F (110°C). The transmission uid temperature
can be monitored with the gages button on the DIC.

Control of a Vehicle
The following three systems help to control your
vehicle while driving — brakes, steering, and
accelerator. At times, as when driving on snow
or ice, it is easy to ask more of those control
systems than the tires and road can provide.
Meaning, you can lose control of your vehicle.
SeeTraction Control System (TCS) on page 281
andActive Handling System on page 283.
Adding non-dealer/non-retailer accessories
can affect your vehicle’s performance. See
Accessories and Modications on page 319.
Braking
SeeBrake System Warning Light on page 196.
Braking action involves perception time and
reaction time. First, you have to decide to push
on the brake pedal. That is perception time.
Then you have to bring up your foot and do it.
That is reaction time.Average reaction time is about three-fourths of a
second. But that is only an average. It might
be less with one driver and as long as two or
three seconds or more with another. Age, physical
condition, alertness, coordination, and eyesight
all play a part. So do alcohol, drugs, and
frustration. But even in three-fourths of a second,
a vehicle moving at 60 mph (100 km/h) travels
66 feet (20 m). That could be a lot of distance in an
emergency, so keeping enough space between
your vehicle and others is important.
And, of course, actual stopping distances vary
greatly with the surface of the road, whether it is
pavement or gravel; the condition of the road,
whether it is wet, dry, or icy; tire tread; the
condition of the brakes; the weight of the vehicle;
and the amount of brake force applied.
Avoid needless heavy braking. Some people drive
in spurts — heavy acceleration followed by heavy
braking — rather than keeping pace with traffic.
This is a mistake. The brakes might not have time
to cool between hard stops. The brakes will wear
out much faster if you do a lot of heavy braking.
278

If you keep pace with the traffic and allow realistic
following distances, you will eliminate a lot of
unnecessary braking. That means better braking
and longer brake life.
If your vehicle’s engine ever stops while you are
driving, brake normally but do not pump the
brakes. If you do, the pedal could get harder to
push down. If the engine stops, you will still have
some power brake assist. But you will use it
when you brake. Once the power assist is used
up, it can take longer to stop and the brake pedal
will be harder to push.
Under certain weather or operating conditions,
occasional brake squeak, squeal, or other
noise might be heard with your vehicle’s
performance braking system. This brake system
is designed for superior fade resistance and
consistent operation using high performance
brake pads. Brake noise is normal and does
not affect system performance.
Adding non-dealer/non-retailer accessories
can affect your vehicle’s performance. See
Accessories and Modications on page 319.Anti-Lock Brake System (ABS)
Your vehicle has the Anti-Lock Brake
System (ABS), an advanced electronic braking
system that will help prevent a braking skid.
When you start the engine and begin to drive
away, ABS will check itself. You might hear
a momentary motor or clicking noise while this
test is going on, and you might even notice that
the brake pedal moves a little. This is normal.
If there is a problem
with ABS, this warning
light will stay on.

System Warning
Light on page 197.
