modules, ceiling or pillar garnish trim,
overhead console, front sensors, side
impact sensors, or airbag wiring.
Your dealer and the service manual
have information about the location of
the airbag sensors, sensing and
diagnostic module, and airbag wiring.
In addition, the vehicle has a
passenger sensing system for the front
outboard passenger position, which
includes sensors that are part of the
passenger seat. The passenger sensing
system may not operate properly if
the original seat trim is replaced with
non-GM covers, upholstery, or trim; or
with GM covers, upholstery, or trim
designed for a different vehicle. Any
object, such as an aftermarket seat
heater or a comfort-enhancing pad or
device, installed under or on top of
the seat fabric, could also interfere
with the operation of the passenger
sensing system. This could either
prevent proper deployment of the
passenger airbag(s) or prevent the
passenger sensing system from
properly turning off the passenger
airbag(s). SeePassenger Sensing
System 073. If the vehicle has rollover roof-rail
airbags, see
Different Size Tires and
Wheels 0282 for additional important
information.
If you have to modify your vehicle
because you have a disability and you
have questions about whether the
modifications will affect the vehicle's
airbag system, or if you have
questions about whether the airbag
system will be affected if the vehicle is
modified for any other reason, see
your dealer.
Airbag System Check
The airbag system does not need
regularly scheduled maintenance or
replacement. Make sure the airbag
readiness light is working. See Airbag
Readiness Light 0113.
Caution
If an airbag covering is damaged,
opened, or broken, the airbag may
not work properly. Do not open or
break the airbag coverings. If there
are any opened or broken airbag

Fuel Gauge
When the ignition is on, the fuel
gauge indicates about how much fuel
is left in the tank.
There is an arrow near the fuel gauge
pointing to the side of the vehicle the
fuel door is on.
When the indicator nears empty, the
low fuel light comes on. There still is
a little fuel left, but the vehicle should
be refueled soon.Here are four things that some owners
ask about. None of these show a
problem with the fuel gauge:
.
At the service station, the fuel
pump shuts off before the gauge
reads full.
. It takes a little more or less fuel to
fill up than the gauge indicated.
For example, the gauge may have
indicated the tank was half full,
but it actually took a little more or
less than half the tank's capacity
to fill the tank.
. The gauge moves a little while
turning a corner or speeding up.
. The gauge takes a few seconds to
stabilize after the ignition is
turned on, and goes back to empty
when the ignition is turned off.
Engine Coolant
Temperature Gauge
This gauge measures the engine
coolant temperature.
The warning area at the far end of the
gauge may appear shaded or may be
colored red.
If the pointer approaches the warning
area, or the shaded thermostat symbol
the engine may be too hot.

turn off the reminder light and/or
chime, remove the object from the
seat or buckle the safety belt.
Airbag Readiness Light
This light shows if there is an
electrical problem with the airbag
system. The system check includes
the airbag sensor(s), the passenger
sensing system, the pretensioners, the
airbag modules, the wiring, and the
crash sensing and diagnostic module.
For more information on the airbag
system, seeAirbag System 067.
The airbag readiness light comes on
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 0134.
Passenger Airbag Status
Indicator
The vehicle has a passenger sensing
system. See Passenger Sensing System
0 73 for important safety information.
The passenger airbag status indicator
is in the overhead console.
When the vehicle is started, the
passenger airbag status indicator will
light the symbol for on and off for
several seconds as a system check.
Then, after several more seconds, the
status indicator will light either the on
or off symbol to let you know the
status of the front outboard passenger
frontal airbag and knee airbag.
If the on symbol is lit on the
passenger airbag status indicator, it
means that the front outboard
passenger frontal airbag and knee
airbag are allowed to inflate.
If the off symbol is lit on the airbag
status indicator, it means that the
passenger sensing system has turned
off the front outboard passenger
frontal airbag and knee 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. See
Airbag Readiness Light0113 for
more information, including
important safety information.
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, or is
flashing, the Driver Information
Center (DIC) also displays a message.
See
Battery Voltage and Charging
Messages 0127.
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
(Check Engine Light)
This light is part of the vehicle’s
emission control on-board diagnostic
system. If this light is on while the
engine is running, a malfunction has
been detected and the vehicle may
require service. The light should come on to show that it is working when
the ignition is in Service Only Mode.
See
Ignition Positions 0185.
Malfunctions are often indicated by
the system before any problem is
noticeable. Being aware of the light
and seeking service promptly when it
comes on may prevent damage.
Caution
If the vehicle is driven continually
with this light on, the emission
control system may not work as
well, the fuel economy may be
lower, and the vehicle may not run
smoothly. This could lead to costly
repairs that might not be covered
by the vehicle warranty.

Cadillac ATS/ATS-V Owner Manual (GMNA-Localizing-MidEast-10287885) -
2017 - crc - 6/16/16
INSTRUMENTS AND CONTROLS 115
Caution
Modifications to the engine,
transmission, exhaust, intake,
or fuel system, or the use of
replacement tires that do not meet
the original tire specifications, can
cause this light to come on. This
could lead to costly repairs not
covered by the vehicle warranty.
This could also affect the vehicle’s
ability to pass an Emissions
Inspection/Maintenance test. See
Accessories and Modifications0232.
If the light is f lashing : A
malfunction has been detected that
could damage the emission control
system and increase vehicle
emissions. Diagnosis and service may
be required.
To help prevent damage, reduce
vehicle speed and avoid hard
accelerations and uphill grades.
If towing a trailer, reduce the amount
of cargo being hauled as soon as
possible. If the light continues to flash, find a
safe place to park. Turn the vehicle off
and wait at least 10 seconds before
restarting the engine. If the light is
still flashing, follow the previous
guidelines and see your dealer for
service as soon as possible.
If the light is on steady :
A
malfunction has been detected.
Diagnosis and service may be
required.
Check the following:
. For vehicles without the capless
fuel system, a loose or missing
fuel cap may cause the light to
come on. See Filling the Tank
0 227. A few driving trips with the
cap properly installed may turn
the light off.
. For vehicles with the capless fuel
system, if fuel has been added to
the vehicle using the capless
funnel adapter, make sure that it
has been removed. See “Filling the
Tank with a Portable Gas Can ”
under Filling the Tank 0227. The
diagnostic system can detect if the
adapter has been left installed in
the vehicle, allowing fuel to evaporate into the atmosphere.
A few driving trips with the
adapter removed may turn off the
light.
. Poor fuel quality can cause
inefficient engine operation and
poor driveability, which may go
away once the engine is warmed
up. If this occurs, change the fuel
brand. It may require at least one
full tank of the proper fuel to turn
the light off. See Fuel0226.
If the light remains on, see your
dealer.
Emissions Inspection and
Maintenance Programs
If the vehicle requires an Emissions
Inspection/Maintenance test, the test
equipment will likely connect to the
vehicle's Data Link Connector (DLC).

Cadillac ATS/ATS-V Owner Manual (GMNA-Localizing-MidEast-10287885) -
2017 - crc - 6/16/16
116 INSTRUMENTS AND CONTROLS
The DLC is under the instrument
panel to the left of the steering wheel.
Connecting devices that are not used
to perform an Emissions Inspection/
Maintenance test or to service the
vehicle may affect vehicle operation.
SeeAdd-On Electrical Equipment 0230.
See your dealer if assistance is needed.
The vehicle may not pass
inspection if:
. The light is on when the engine is
running.
. The light does not come on when
the ignition is in Service
Only Mode.
. Critical emission control systems
have not been completely
diagnosed. If this happens, the
vehicle would not be ready for
inspection and might require
several days of routine driving
before the system is ready for
inspection. This can happen if the
12-volt battery has recently been
replaced or run down, or if the
vehicle has been recently serviced. See your dealer if the vehicle will not
pass or cannot be made ready for
the test.
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 is
a problem with the braking system.
Have the brake system inspected
right away.
This light should come on briefly
when the engine is started. If it does
not come on then, have it fixed so it
will be ready to warn you if there is a
problem. If the light comes on and stays on,
there is a base brake 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.
