WARNING
Never shift the Subaru Ascent transmission from "P" or "N" into "D" or "R" while pressing the accelerator pedal. This can cause sudden and uncontrolled vehicle movement.
CAUTION
Failure to do so may result in transmission damage or unsafe driving conditions.
This may lead to unexpected behavior or mechanical failure.
Avoid leaving the vehicle parked in other gear positions, as this may lead to battery discharge over time.
The Subaru Ascent transmission and electronic systems are designed for durability and smooth operation, but proper handling and routine maintenance are essential to ensure long-term reliability and safe driving performance.
