Software Information :
Displays open source software
information.
Speedometer
The speedometer shows the
vehicle speed in either
kilometers per hour (km/h) or
miles per hour (mph).
Odometer
The odometer shows how far
the vehicle has been driven, in
either kilometers or miles.
Trip Odometer
The trip odometer shows how
far the vehicle has been driven
since the trip odometer was

per minute (rpm).
For vehicles with the Stop/
Start system, when the
ignition is on, the tachometer
indicates the vehicle status.
When pointing to AUTO STOP,
the engine is off but the
vehicle is on and can move.
The engine could auto start at
any time. When the indicator
points to OFF, the vehicle
is off.
When the engine is on, the
tachometer will indicate the
engine’s revolutions per
minute (rpm). The tachometer
may vary by several hundred
rpm, during Auto Stop mode,
when the engine is shutting
off and restarting.
Fuel Gauge
When the ignition is on, the
fuel gauge indicates the
approximate amount of fuel
left in the tank.
There is an arrow near the
fuel gauge pointing to the side
of the vehicle the fuel door
is on.

Instruments and Controls 123
The fuel gauge may:
.Take a little more, or less
fuel to fill up than it
indicates. For example, the
gauge may have indicated
the tank is half full, but it
actually will take a little
more, or less than half the
tank's capacity to fill
the tank.
.Moves a little while turning a
corner, speeding up,
or braking.
.Take a few seconds to
stabilize after the ignition is
turned on and goes back to
empty when the ignition is
turned off.
These are normal conditions,
none of which indicate a
problem with the fuel gauge.
Engine Coolant
Temperature Gauge
Metric
English This gauge measures the
temperature of the vehicle's
engine.
While driving under normal
operating conditions, if the red
LED is illuminated, the engine
is too hot. Pull off the road,

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.
Passenger Airbag
Status Indicator
The vehicle has a passenger
sensing system. See
Passenger Sensing System
0 72 for important safety
information. The overhead
console has a passenger
airbag status indicator.
When the vehicle is started,
the passenger airbag status
indicator will light ON and OFF,
and the symbols for on and
off, for several seconds as a
system check. Then, after
several more seconds, the
status indicator will light either
ON or OFF, and either the
symbol for on or off, to let you
know the status of the front
outboard passenger frontal
airbag and knee airbag.
If the word ON, and the on
symbol, are 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 word OFF, and the off
symbol, are lit on the
passenger 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
Light
0124 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.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. Find a safe
place to stop the vehicle.
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 Mode. See Ignition
Positions
0247.
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.
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

Caution (Continued)
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
Modifications0327.
If the light is flashing : 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:
.If fuel has been added to the
vehicle using the capless fuel
funnel adapter, make sure
that it has been removed.
See “Filling the Tank with a
Portable Gas Can” under
Filling the Tank 0311. 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
Recommended Fuel 0310.
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 XT4 Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
16412876) - 2023 - CRC - 3/25/22
128 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. See Add-On
Electrical Equipment0325.
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 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.
