Cadillac Escalade EXT Warning Lights: What They Mean

Red: stop or act now

Brake System Warning Light

Possible brake problem or low brake fluid; one of the two brake circuits may not be working, so braking may be weaker.
What to do: Pull off the road and stop carefully. If the light stays on, have the vehicle towed for service. PDF page 132

Other warnings and indicators

Airbag Readiness Light

Electrical problem in the airbag system; airbags might not inflate in a crash or could inflate without one.
What to do: Have the vehicle serviced right away. If the light does not come on at startup, have it fixed immediately. PDF page 127

Charging System Light

Possible charging system problem, such as a generator drive belt or electrical fault, if it stays on or comes on while driving.
What to do: Have it checked right away. If you must drive briefly, turn off accessories such as the radio and air conditioner. PDF page 129

Malfunction Indicator Lamp

The OBD II system has detected an emissions-related problem; diagnosis and service might be required.
What to do: Have the vehicle diagnosed and serviced. If it does not come on at start-up, have the dealer service it. PDF page 129

Antilock Brake System (ABS) Warning Light

Problem with the antilock brakes. If the regular brake light is off, normal brakes still work; if both are on, regular brakes have a problem.
What to do: Turn the ignition off, stop safely if driving, then restart. If the light stays on or returns, the vehicle needs service. PDF page 132

Low Tire Pressure Warning Light

Significant pressure loss in a tire. Flashing then staying on indicates a TPMS malfunction, so low pressure may not be detected.
What to do: Stop as soon as possible and inflate tires to the pressure on the Tire and Loading Information label. PDF page 377

Traction Control System (TCS)/StabiliTrak® Light

Comes on briefly at engine start as a check; if it stays on or does not come on, the system has a problem.
What to do: Have the vehicle serviced by the dealer. PDF page 133

StabiliTrak® OFF Light

StabiliTrak is turned off, so the system does not assist in controlling the vehicle.
What to do: Turn the StabiliTrak/TCS system back on and the light goes off. PDF page 133

Passenger Safety Belt Reminder Light

Reminds the front passenger to buckle up; it may also trigger if an object is placed on the seat.

Comes on when Tow/Haul Mode has been activated. PDF page 133

Summarized in our own words from the 2013 Cadillac Escalade EXT owner's manual (AI-assisted; every light name was matched against its cited page 2026-10-18). Your vehicle may not have every light, and other years can differ. A red warning that stays on usually means stop safely and check: your manual has the final word.
