A warning light in a Toyota Highlander Hybrid is easier to handle when you separate the signal by urgency first. Red brake, charging, coolant, oil-pressure, steering, and airbag alerts need faster action than amber driver-assist or tire-pressure warnings.
Model year, trim, drivetrain, and market equipment can change the icon set and the message shown in the cluster. Use this guide as quick triage, then compare your exact vehicle in the official Toyota owner's manual.

14 Highlander Hybrid warning lights to sort first
| Type | Light | Meaning | Action |
|---|---|---|---|
| Stop now |  Brake system, red | Low brake fluid or brake-system fault | Stop safely and do not keep driving if it stays on. |
| Inspect soon |  Brake system, amber | Regenerative or electronic brake issue | Reduce driving and arrange inspection. |
| Heat |  Coolant temperature | Engine coolant temperature is too high | Pull over, let the vehicle cool, and follow the manual. |
| Hybrid heat |  Hybrid system overheat | Hybrid drive temperature is too high | Stop hard driving and let the system cool. |
| Electrical |  Charging system | Charging-system malfunction | Reduce electrical load, stop safely, and contact service. |
| Engine |  Oil pressure | Engine oil pressure is too low | Stop immediately to reduce engine damage risk. |
| Diagnosis |  Malfunction indicator | Hybrid, engine-control, or throttle issue | Get diagnosis quickly if drivability changes. |
| Safety |  SRS | Airbag or pretensioner fault | Do not leave occupant protection unresolved. |
| Braking |  ABS | ABS or brake-assist malfunction | Drive cautiously and inspect promptly. |
| Steering |  Electric power steering | Steering-assist malfunction | If the wheel feels heavy, slow down and stop safely. |
| Tires |  Tire pressure | Low pressure, puncture, or TPMS fault | Check all tires before your next high-speed drive. |
| Lane assist |  LTA | Lane tracing assist fault or limitation | Do not rely on lane assistance until confirmed. |
| Front assist |  PCS | Pre-collision system fault or limitation | Check blocked sensors and follow the message display. |
| Stability |  Slip indicator | VSC, TRAC, trailer sway, or hill-start assist issue | Flashing can mean intervention; steady light needs diagnosis. |
Red lights mean stop first
Brake, charging, coolant temperature, oil pressure, SRS, and red steering warnings deserve immediate attention. If one stays on while driving, move to a safe place, note the message, and follow the official manual before continuing.
Hybrid warnings need separate judgment
On a Highlander Hybrid, the malfunction light can involve the hybrid system as well as engine control or throttle control. Do not treat unusual brake feel, charging warnings, hybrid overheat, or reduced power like a simple gasoline-car alert.
Change the model year before you trust a match
