ECO light indicates that the vehicle's economy mode is activated. The ECO mode is divided into active ECO driving mode and non-active ECO driving mode. More related information is as follows: 1. Body dimensions: The Lexus RX has a length, width, and height of 4890mm, 1895mm, and 1710mm respectively, with a wheelbase of 2790mm. It is equipped with a 6-speed automatic transmission and has a maximum horsepower of 231. 2. Configuration: The Lexus RX has a fuel tank capacity of 72.5L, a maximum torque of 350 Nm, and uses a turbocharged engine with an engine displacement of 1998ml. The front suspension is a MacPherson independent suspension with a stabilizer bar, and the rear suspension is a double-wishbone independent suspension with a stabilizer bar. The tire specification is 235/65R18.

The ECO light indicates your is currently in fuel-saving mode. This is an intelligent function designed by the manufacturer, essentially acting like a computer butler managing your fuel consumption. Simply put, the system slightly slows down throttle response to prevent sudden acceleration from wasting gasoline, while also automatically reducing air conditioning and electrical power. This mode can be activated either manually or automatically when the vehicle detects smooth driving. Having driven the RX450h extensively, I've found maintaining a steady speed around 60 km/h most easily triggers ECO mode. If you're in a hurry and find the acceleration sluggish, simply press the driving mode button on the center console to switch back to normal mode.

The green ECO light staying on means the fuel-saving mode is activated. designed this to remind you that you're currently driving economically, as the system automatically limits throttle response and optimizes gear shift logic. I've noticed it stays in ECO mode most of the time during city driving, especially with hybrid models where it always lights up during battery-powered operation. As long as you avoid sudden acceleration or hard braking, this indicator will remain on. If you really don't like it, just look for the driving mode selector button below the left side of the steering wheel to switch modes.

Having the ECO mode on is a good thing, it means the gasoline you feed your isn't wasted. This system automatically activates during steady-speed driving, adjusting the engine output to an energy-saving state, such as shifting gears earlier and automatically reducing air conditioning fan speed. Based on data I've observed in car owner groups, using ECO mode in urban driving can save about 8% fuel. The reason it stays on might be because it's set to default activation, or the driver has exceptionally good driving habits. To turn it off, simply rotate the knob near the gear shift to switch to NORMAL mode, and you'll immediately regain normal power.

The constantly illuminated ECO indicator means Lexus's fuel-saving assistant is at work. The system saves fuel by adjusting throttle sensitivity and shifting gears earlier. I've noticed temperature also affects it - in summer, the ECO light stays on much longer because the air conditioning power consumption is automatically limited. If your brand-new car keeps the ECO light on, it's completely normal as the system defaults to this mode from the factory. To change driving styles later, simply press the DRIVE MODE button on the center console - when Sport mode's red indicator lights up, you'll get much snappier acceleration.
