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 is empty, the low fuel light comes on. There still is a little fuel left, but the vehicle should be refueled soon.
Here are three 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 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, speeding up, or braking.
  • 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 Gauge2020 Cadillac CT4-Instrument Cluster-fig 5

problem with the airbag system. It is located in the instrument cluster. 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.
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.

Passenger Airbag Status Indicator
The vehicle has a passenger sensing system. See Passenger Sensing System 0 58 for important safety information. The overhead console has a passenger airbag status indicator.2020 Cadillac CT4-Instrument Cluster-fig 10
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 as a 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 front outboard passenger frontal airbag.
If the word ON, or the on symbol, is lit on the passenger airbag status indicator, it means that the front outboard passenger frontal airbag is allowed to 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 front outboard 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. See Airbag Readiness Light 0 98 for more information, including important safety information.

2020 Cadillac CT4-Instrument Cluster-fig 11Charging 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.

2020 Cadillac CT4-Instrument Cluster-fig 12Malfunction Indicator Lamp (Check Engine Light)


This light is part of the vehicle’s emission control onboard 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.
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 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 Modifications 0 258.

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 0 243. 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 Engine) or Recommended Fuel (3.6L V6 Engine)
    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).2020 Cadillac CT4-Instrument Cluster-fig 13

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 Equipment 0 256. 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 will 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 electronically controlled hydraulic brake circuits. If a fault is detected, valves are adjusted to allow the brake pedal to push brake fluid directly into the hydraulic brake circuits. When a fault occurs, the brake system warning light comes on, and Driver Information Center (DIC) messages may be displayed. Vehicle speed may also be limited and the amount of brake pedal force applied may need to increase. Have the vehicle brake system serviced as soon as possible.2020 Cadillac CT4-Instrument Cluster-fig 14
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 if there is a problem.
The brake system warning light may also come on when the parking brake is set, if the vehicle has low brake fluid, or if the brakes are severely faded. See Brake Fluid 0 268. If the brakes are overheated, DIC messages may be displayed, and the vehicle speed may be limited. If the brake fluid is not low, if the brakes are not overheated, and if the parking brake is fully released, then the vehicle has a brake problem. Have the vehicle brake system serviced as soon as possible.
If the light comes on while driving, pull off the road and stop carefully. The pedal might be harder to push, or the 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.
