Chevrolet HHR Warning Lights: What They Mean

Other warnings and indicators

Brake System Warning Light

Brake problem, or parking brake is set or not fully released. Stays on after release means a brake fault; stopping may take longer.
What to do: Pull off the road and stop carefully, release parking brake, try restarting once or twice; if still on, have vehicle towed for service. PDF page 185

Antilock Brake System (ABS) Warning Light

If it stays on or comes on while driving, the ABS needs service; the regular brakes still work unless the brake light is also on.
What to do: Stop safely, turn ignition off, restart to reset. If light stays on or returns, have the vehicle serviced. PDF page 186

Electronic Stability Control (ESC)/Traction Control System (TCS) Indicator/Warning Light

Steady: TCS and possibly ESC disabled or not working. Flashing: system is actively limiting wheel spin or aiding directional control.
What to do: Check DIC messages to see which system is off or faulty; if not working, see your dealer for service. PDF page 187

Enhanced Traction System (ETS) Indicator/Warning Light

Steady: ETS disabled, so wheel spin is not limited. Flashing: ETS is actively limiting wheel spin.
What to do: Check DIC messages to see if the system was turned off or needs service. PDF page 186

Low Tire Pressure Telltale

Tire pressure is low; flashing about a minute then staying on indicates a TPMS malfunction, so low pressure may go undetected.
What to do: Stop and check tires soon and inflate to proper pressure. Check the TPMS telltale after replacing tires or wheels. PDF page 332

Passenger Airbag Status Indicator

ON means the right front passenger frontal airbag is enabled; OFF means it is turned off. Both lit or none lit after several seconds suggests a fault.
What to do: If both lights stay on or neither lights, see your dealer for service. PDF page 183

Summarized in our own words from the 2011 Chevrolet HHR 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.
