WARNING: This page is about a different car, the 2019 Buick Cascada, 2018 Buick Cascada, and 2017 Buick Cascada. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
All dimensions are measured vertical to the ground. Trim height should be within ±10 mm (±0.39 in) to be considered correct.
Use the following procedure to check the P and R dimensions:
- Lift the front bumper of the vehicle up about 38 mm (1.5 in).
- Gently remove your hands and let the vehicle settle.
- Repeat this operation 2 more times for a total of 3.
- P height is measured vertically from the ground to the bottom lip of the wheel opening through the centerline of the front wheel.
- Push the front bumper of the vehicle down about 38 mm (1.5 in).
- Gently remove your hands and let the vehicle settle down.
- Repeat this operation 2 more times for a total of 3.
- Measure the P height as in step 4.
- The true P height measurement is the average of the measurements taken in step 4 and 8.
- Repeat the above steps on the rear of the vehicle for the R heights.
