If the light continues to flash, stop
and park the vehicle. Turn the
vehicle off, wait at least 10 seconds,
and restart the engine. If the light is
still flashing, follow the previous
steps and see your dealer for
service as soon as possible.
Light On Steady:An emission
control system malfunction has
been detected on the vehicle.
Diagnosis and service might be
required.
The following may correct an
emission system malfunction:
.Check that the fuel cap is fully
installed. See Filling the Tank on
page 9‑51. The diagnostic
system can determine if the
fuel cap has been left off or
improperly installed. A loose or
missing fuel cap allows fuel to
evaporate into the atmosphere.
A few driving trips with the cap
properly installed should turn the
light off.
.Check that good quality fuel is
used. Poor fuel quality causes
the engine not to run as
efficiently as designed and may
cause: stalling after start-up,
stalling when the vehicle is
changed into gear, misfiring,
hesitation on acceleration,
or stumbling on acceleration.
These conditions might go away
once the engine is warmed up.
If one or more of these
conditions occurs, change the
fuel brand used. It will require at
least one full tank of the proper
fuel to turn the light off.
See Recommended Fuel on
page 9‑48.
If none of the above have made
the light turn off, your dealer can
check the vehicle. The dealer has
the proper test equipment and
diagnostic tools to fix any
mechanical or electrical problems
that might have developed.Emissions Inspection and
Maintenance Programs
Some local governments may have
programs to inspect the on-vehicle
emission control equipment.
For the inspection, the emission
system test equipment is
connected to the vehicle’s Data
Link Connector (DLC).
The DLC is under the instrument
panel to the left of the steering
wheel. See your dealer if assistance
is needed.
The vehicle may not pass
inspection if:
.The malfunction indicator lamp is
on with the engine running, or if
the vehicle is placed in Service
Only Mode and the malfunction
indicator lamp does not come
Black plate (21,1)Chevrolet Corvette Owner Manual - 2012
Instruments and Controls 5-21
on. See your dealer for
assistance in verifying proper
operation of the malfunction
indicator lamp.
.The OBD II (On-Board
Diagnostics) system
determines that critical emission
control systems have not been
completely diagnosed. The
vehicle would be considered not
ready for inspection. This can
happen if the 12-volt battery has
recently been replaced or run
down. The diagnostic system is
designed to evaluate critical
emission control systems during
normal driving. This can take
several days of routine driving.
If this has been done and the
vehicle still does not pass the
inspection for lack of OBD II
system readiness, your dealer
can prepare the vehicle for
inspection.
Brake System Warning
Light
The vehicle brake system consists
of two hydraulic circuits. If one
circuit is not working, the remaining
circuit can still work to stop the
vehicle. For normal braking
performance, both circuits need to
be working.
MetricEnglish
This light comes on briefly while
starting the engine. If it does not
come on, have it fixed so it is ready
to warn if there is a problem.
{WARNING
The brake system might not be
working properly if the brake
system warning light is on.
Driving with the brake system
warning light on can lead to a
crash. If the light is still on after
the vehicle has been pulled off
the road and carefully stopped,
have the vehicle towed for
service.
If this warning light stays on after
the engine is started, the parking
brake may still be set or there could
be a brake problem. Refer to
Parking Brake on page 9‑36 to
see if it is set. If the parking brake
is not set, have the brake system
inspected right away.

5-22 Instruments and Controls
If the light comes on while driving
and a CHECK BRAKE FLUID
message shows on the DIC, pull off
the road and stop carefully. The
pedal may be harder to push or the
pedal may go closer to the floor.
It may take longer to stop. If the
light is still on, have the vehicle
towed for service. SeeTowing the
Vehicle on page 10‑82 andBrake
System Messages on page 5‑36 for
more information.
Antilock Brake System
(ABS) Warning Light
For vehicles with the Antilock Brake
System (ABS), this light comes on
briefly when the engine is started. If it does not, have the vehicle
serviced by your dealer. If the
system is working normally the
indicator light then goes off.
If the ABS light stays on, turn the
ignition off. If the light comes on
while driving, stop as soon as it is
safely possible and turn the ignition
off. Then start the engine again to
reset the system. If the ABS light
stays on, or comes on again while
driving, the vehicle needs service.
If the regular brake system warning
light is not on, the vehicle still has
brakes, but not antilock brakes.
If the regular brake system warning
light is also on, the vehicle does not
have antilock brakes and there is a
problem with the regular brakes.
See
Brake System Warning Light on
page 5‑21.
One-to-Four Shift Light
(Manual Transmission)
When this light comes on, the
vehicle can only be shifted from
1 (First) to 4 (Fourth) instead of
1 (First) to 2 (Second).
The shift must be completed into
4 (Fourth) to turn off this feature.
This helps the vehicle get the best
possible fuel economy.
After shifting to 4 (Fourth), the
vehicle can be downshifted to a
lower gear.
Notice: Forcing the shift lever
into any gear except 4 (Fourth)
when the 1 TO 4 SHIFT light
comes on may damage the
transmission. Shift only from
1 (First) to 4 (Fourth) when the
light comes on.
