Use caution during the steps to avoid marring or scratching the class "A" paint finish.

Apply two layers of masking tape around the rear end spoiler (1) to prevent paint damage.
Warm the rear end spoiler (1) using a hair dryer or heat gun not exceeding 79°C (175°F). Care should be given to protect the interfacing surfaces.
Using a suitable plastic trim tool, gently pry upwards to release the rear end spoiler (1).
