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
last reset.
The trip odometer is accessed
and reset through the Driver
Information Center (DIC). See
Driver Information Center
(DIC)0144.
Tachometer
The tachometer displays the
engine speed in revolutions
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.
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.
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,
stop the vehicle, and turn off
the engine as soon as
possible.

to yourself or others, have
the vehicle serviced right
away. See Airbag Readiness
Light0132 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
0257.
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.

Instruments and Controls 135
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
Modifications0363.
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 0344. 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 (2.0L L4
Turbo Engine)
0343 or
Recommended Fuel (3.6L
V6 Engine) 0343.
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 XT6 Owner Manual (GMNA-Localizing-U.S./Canada-16405819) -
2023 - CRC - 3/22/22
136 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 Equipment0360.
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.
Brake System
Warning Light
MetricEnglish
This light comes on briefly
when the vehicle is turned on
to show that the light is
working. 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 brake problem.
Have the brake system
inspected right away. This
light may come on if the brake
fluid is low. See Brake Fluid
0
384.
If the light comes on while
driving, pull off the road and
stop carefully. If equipped with
electric brake boost, vehicle
speed may be limited when the
brake system warning light
comes on. The brake pedal
might be harder to push,
or the brake pedal may go
closer to the floor. It could
take longer to stop. If the light
is still on, have the vehicle
towed for service. See
Transporting a Disabled
Vehicle 0437.

warranty.
If the engine oil pressure
light comes on while driving:
1. Stop in a safe location and turn off the engine.
2. Check the oil level. See Engine Oil 0370.
3. Add oil if the oil level is below the normal

When the engine is off and the
vehicle is on, the light should
remain illuminated. If it does
not come on under either
condition, contact your dealer.
If the light comes on and stays
on when the engine is running,
it may not have adequate oil
pressure. The oil level may be
low or there may be some
other oil system problem. Turn
the engine off when it is safe
to do so and contact your
dealer.
Low Fuel Warning
Light
A Low Fuel Warning Light
near the fuel gauge comes on
briefly when the ignition is
