Toyota 4LO warning light flashing can be inspected and repaired at a 4S shop or auto repair shop. Related introduction: 1. Cause of flashing: The Toyota 4LO light indicates that the vehicle has entered the low-speed cruise system, which is the automatic hill-climbing function. During daily driving, it is necessary to refuel in advance. Diesel engines must never run out of diesel before refueling. A diesel engine running on empty will continue to idle and draw in air, which can severely damage the engine. 2. Extension: Toyota 4LO diesel engines are highly durable. Diesel engines operate at relatively lower RPMs, reducing wear on engine components. At the same time, diesel engines have different oil requirements compared to gasoline engines and require specialized engine oil. The oil change interval should not exceed 6000 kilometers. Additionally, regular maintenance of the three filters—air filter, oil filter, and diesel filter—should be emphasized.

What is DRIVE MODE in an automatic transmission car?

DRIVE MODE in an automatic transmission car refers to the driving mode of the vehicle. There are typically three driving modes: ECO (Economy Mode), NORMAL (Standard Mode), and SPORT (Sport Mode). Below is a detailed introduction to automatic transmission cars: Overview: An automatic transmission car generally refers to a vehicle that uses an automatic transmission (AT) to adjust the speed. While driving, the control system of the automatic transmission automatically selects the appropriate gear based on the engine's speed and load, replacing the driver's subjective judgment of timing and gear shifting operations. Additional Information: Automatic transmission cars usually use a hydraulic transmission device to replace the mechanical clutch in manual transmission cars, hence there is no clutch pedal. When the engine speed is low, the torque transmitted by the fluid is limited and insufficient to propel the car forward.

Is It Normal for a New Car's Exhaust Pipe to Rust?

Rust on the exhaust pipe is actually a very normal phenomenon. Since the surface temperature of the exhaust pipe can become extremely high during operation, and manufacturers generally apply paint, the surface is essentially fully exposed. Over time, exposure to various acidic and alkaline substances, sewage, and other corrosive elements, combined with the high-temperature working environment, makes it inevitable for the exhaust pipe to rust. Maintenance Tips: Regular maintenance should include cleaning the drainage holes to prevent clogging. When driving in the rain or passing through deep water areas, water may seep into the exhaust pipe. Additionally, during car washing, avoid spraying water directly into the exhaust pipe. If water enters the exhaust pipe, let the engine idle for more than ten minutes to allow the water to gradually drain out.
