Caution / Notice / Hint

WARNING: This page is about a different car, the 2025 Lexus NX 350h, 2024 Lexus NX 350h, 2023 Lexus NX 350h, and 2022 Lexus NX 350h. However, it is still accessible from the selected car via links, so may be relevant.

WARNING:

The engine assembly with transaxle is very heavy. Be sure to follow the procedure described in the repair information, or the engine lifter may suddenly drop or the engine assembly with transaxle may fall off the engine lifter.
To prevent burns, do not touch the engine, exhaust manifold or other high temperature components while the engine is hot.
