Why does the brake light on the dashboard illuminate when stepping on the brake?

Reasons for the dashboard brake light illuminating when stepping on the brake: 1. Severe wear of brake pads. The manufacturer has installed a warning line on the brake pads. When the brake pads reach their usage limit, an alarm will be triggered. It is necessary to regularly inspect the brake pads on the tires, measure the thickness of the brake pads with a gauge, and replace them immediately if the wear is significant. 2. When braking, the brake fluid is compressed into the pipelines and the brake calipers. If the brake fluid level drops, the fluid level sensor will detect it and trigger an alarm through the warning light. It is important to regularly check the brake fluid reservoir for low levels and add brake fluid immediately. 3. There might be a circuit break affecting the dashboard warning light. A multimeter can be used to test the brake pad warning circuit, brake fluid level warning circuit, and the handbrake switch circuit to determine if there is a problem with the wiring and to perform immediate repairs and inspections.

Can the Land Cruiser 4000 use 92 octane gasoline?

Land Cruiser 4000 cannot use 92 octane gasoline. Toyota recommends using 95 octane gasoline for this vehicle for the following reasons: 1. Gasolines with different octane ratings have different octane values. Higher octane gasoline has higher octane value, and gasoline with higher octane value has better anti-knock performance. 2. Using 95 octane gasoline allows more complete combustion, which can reduce carbon deposits and provide better power output. 3. If 92 octane gasoline is used in this vehicle, it may cause engine knocking. Engine knocking can lead to decreased power and increased fuel consumption. Severe knocking may even damage the engine.
