Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Adaptive Control
- Uphill/downhill control
Based on the vehicle speed and accelerator opening angle, excess driving force is judged from engine output and acceleration while the road gradient is estimated, in order to select optimum gear range as needed and reduce unnecessary shifting.
- Control during sudden release of accelerator pedal
When accelerator pedal is suddenly released, TCM judges the driver's intention for deceleration and temporarily prohibits shift-up to hold the current gear position in order to ensure engine brake operation.
- Control during braking
Operation frequency of this function in S# mode is higher than that in S mode.
The gear range is held (restraining upshift) or shifted down depending on the driving condition and braking force (deceleration), in order to ensure engine brake operation and driving force for re-acceleration.
- Control during cornering
Operation frequency of this function is as follows: S# > S > I.
Based on the cornering driving judgement from the driving condition and vehicle acceleration (longitudinal and lateral acceleration), unnecessary shift-up is restrained to ensure stable driving force and turning performance.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
