comes on and a chime sounds for
several seconds to remind a driver
to fasten the safety belt, unless the
driver safety belt is already buckled.
The safety belt light flashes for
several seconds, then comes on
solid for several more.
This cycle repeats if the driver

started, a chime sounds for a
number of seconds to remind the
front passenger to buckle their
safety belt. The passenger safety
belt light comes on and stays on for
several seconds, flashes for several
more seconds, and then comes on

Airbag Readiness Light
This light shows if there is an
electrical problem. The system
check includes the airbag sensor,
the pretensioners, the airbag
modules, the wiring, and the crash
sensing and diagnostic module. For
more information on the airbag
system, see

on
page 3‑30.

Black plate (18,1)Cadillac CTS/CTS-V Owner Manual - 2011
5-18 Instruments and Controls
The airbag readiness light comes on
and stays on for several seconds
when the vehicle is started. Then
the light goes out.
{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.
Passenger Airbag Status
Indicator
The vehicle has a passenger
sensing system. SeePassenger
Sensing System
on page 3‑37for
important safety information. The
instrument panel has a passenger
airbag status indicator.
United States
Canada and Mexico
When the vehicle is started, the
passenger airbag status indicator
will light the words ON and OFF,
or the symbols for on and off, for several seconds as a system check.
If the vehicle has remote start, and it
is being used 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 outboard
front passenger frontal airbag is
enabled (may inflate).
If the word OFF or the off symbol is
lit on the passenger airbag status
indicator, it means that the
passenger sensing system has
turned off the outboard 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.

Charging System Light
The charging system light comes on
briefly when the ignition is turned
on, but the engine is not running, as
a check to show the light is working.
It should go out when the engine is
started. If the light stays on, or comes on
while driving, there may be a
problem with the electrical charging
system. Have it checked by your
dealer. Driving while this light is on
could drain the battery.
When this light comes on, the Driver
Information Center (DIC) also
displays a message.
See
Battery Voltage and Charging
Messages on page 5‑31.
If a short distance must be driven
with the light on, be sure to turn off
all accessories, such as the radio
and air conditioner.
Malfunction
Indicator Lamp
A computer system called OBD II
(On-Board Diagnostics-Second
Generation) monitors operation of
the fuel, ignition, and emission
control systems. It ensures that emissions are at acceptable levels
for the life of the vehicle, helping to
produce a cleaner environment.
This light should come on when the
ignition is on, 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.
If the Malfunction Indicator Lamp
comes on and stays on while the
engine is running, this indicates that
there is an OBD II problem and
service is required.

Black plate (22,1)Cadillac CTS/CTS-V Owner Manual - 2011

The vehicle may not pass
inspection if:
.The malfunction indicator lamp is
on with the engine running, or if
the light does not come on when
the ignition is turned to ON/RUN
while the engine is off.
.The critical emission control
systems have not been
completely diagnosed by the
system. This can happen if the
battery has recently been
replaced or if the battery has run
down. The diagnostic system
evaluates 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, your dealer can
prepare the vehicle for
inspection.
