for several seconds when the
vehicle is started. If the light does
not come on then, have it fixed
immediately.
{WARNING
If the airbag readiness light stays
on after the vehicle is started or
comes on while driving, it means
the airbag system might not be
working properly. The airbags in
the vehicle might not inflate in a
crash, or they could even inflate
without a crash. To help avoid
injury, have the vehicle serviced
right away.If there is a problem with the airbag
system, a Driver Information Center
(DIC) message may also come on.
See
Airbag System Messages on
page 5‑35.
Airbag On-Off Light
When the right front passenger
airbag is manually turned off using
the airbag on-off switch on the
instrument panel, if equipped, the
indicator light OFF or the off symbol
will come on and stay on as a
reminder that the airbag has been
turned off. This light will go off when

{WARNING
If the right front passenger airbag
is turned off for a person who is
not in a risk group identified by
the national government, that
person will not have the extra
protection of an airbag. In a
crash, the airbag will not be able
to inflate and help protect the
person sitting there.
Do not turn off the passenger
airbag unless the person sitting
there is in a risk group identified
by the national government. See
Airbag On-Off Switch on
page 3‑23for more on this,
including important safety
information.
{WARNING
If the airbag readiness light ever
comes on and stays on, it means
that something may be wrong
with the airbag system. For
example, the right front
passenger airbag could inflate
even though the airbag on-off
switch is turned off.
To help avoid injury to yourself or
others, have the vehicle serviced
right away. See Airbag Readiness
Light on page 5‑14 for more
information, including important
safety information.
If the word ON or the on symbol is
lit, it means that the right front
passenger frontal airbag is enabled,
and may inflate. See Airbag On-Off
Switch on page 3‑23 for more
information, including important
safety information.
Passenger Airbag Status
Indicator
If the vehicle has a passenger
sensing system, the instrument
panel will have a passenger airbag
status indicator. See Passenger
Sensing System on page 3‑26 for
important safety information.

When the vehicle is started, the
passenger airbag status indicator
will light ON and OFF, or the symbol
for on and off, for several seconds

Black plate (17,1)Chevrolet Express Owner Manual - 2013 - 1stPrintReady - 6/19/12
Instruments and Controls 5-17
as a system check. If you are using
remote start, if equipped, to start the
vehicle from a distance, you may
not see the system check. Then,
after several more seconds, the
status indicator will light either ON
or OFF, or either the on or off
symbol to let you know the status of
the right front passenger frontal
airbag.
If the word ON or the on symbol is
lit on the passenger airbag status
indicator, it means that the right
front passenger frontal airbag is
enabled, and may inflate.
If the word OFF or the off symbol is
lit on the airbag status indicator, it
means that the passenger sensing
system has turned off the right front
passenger frontal airbag.
If, after several seconds, both status
indicator lights remain on, or if there
are no lights at all, there may be a
problem with the lights or the
passenger sensing system. See
your dealer for service.{WARNING
If the airbag readiness light ever
comes on and stays on, it means
that something may be wrong
with the airbag system. To help
avoid injury to yourself or others,
have the vehicle serviced right
away. SeeAirbag Readiness
Light on page 5‑14 for more
information, including important
safety information.
Charging System Light
This light comes on briefly when the
ignition key is turned to START, but
the engine is not running, as a
check to show it is working. If it does not, have the vehicle
serviced by your dealer.
The light should go out once the
engine starts. If it stays on,
or comes on while driving, there
could be a problem with the
charging system. A charging system
message in the Driver Information
Center (DIC) can also appear. See
Battery Voltage and Charging
Messages on page 5‑30
for more
information. This light could indicate
that there are problems with a
generator drive belt, or that there is
an electrical problem. Have it
checked right away. If the vehicle
must be driven a short distance with
the light on, turn off accessories,
such as the radio and air
conditioner.
Malfunction
Indicator Lamp
A computer system called OBD II
(On-Board Diagnostics-Second
Generation) monitors the operation
of the vehicle to ensure emissions

Black plate (20,1)Chevrolet Express Owner Manual - 2013 - 1stPrintReady - 6/19/12
5-20 Instruments and Controls
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.If the warning light comes on, there
could be a brake problem. Have the
brake system inspected right away.
MetricEnglish
This light should come on briefly
when ignition key is turned to ON/
RUN. If it does not come on, have it
fixed so it will be ready to warn if
there is a problem.
When the ignition is on, the brake
system warning light also comes on
when the parking brake is set. See
Parking Brake on page 9‑31 for
more information. The light stays on
if the parking brake does not fully
release. If it stays on after the
parking brake is fully released, it
means the vehicle has a brake
problem. If the light comes on while driving,
pull off the road and stop carefully.
The pedal might be harder to push,
or the pedal might go closer to the
floor. It could take longer to stop.
If the light is still on, have the
vehicle towed for service. See
Towing the Vehicle on page 10‑81.{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.
