Incorrect trim heights can cause bottoming out over bumps. Incorrect trim heights can cause possible damage to the suspension components and symptoms similar to those produced from incorrect wheel alignment. Inspect the trim heights when diagnosing suspension complaints and before checking the wheel alignment.

Perform the following steps before measuring the trim heights:

1. Set the tire pressures to the pressure shown on the tire placard. The tire placard is located on the driver's door.
2. Inspect the fuel level.
3. Add additional weight if necessary to simulate a full tank.
4. Place the front seats in the full back position.
5. Empty the rear compartment except for the spare tire and the jack and a simulated fuel load.
6. Place the vehicle on a level surface, such as an alignment rack.
7. Close the doors.
8. Close the hood.
9. Close the rear compartment lid.

Measure all dimensions vertical to the ground. Trim heights should be within 10 mm (0.4 in) to be considered correct.

1. Lift the front bumper of the vehicle approximately 38 mm (1.5 in). Gently remove your hands. Let the vehicle settle.
2. Push the front bumper down approximately 38 mm (1.5 in). Gently remove your hands. Let the vehicle settle.
3. Measure the J and the P dimensions.
4. Replace the front springs in order to correct the front trim heights.

Repeat the procedure described for measuring the J and P dimensions using the rear bumper and measuring K and R at the appropriate locations. The Automatic Level Control (ALC) system must be operative while taking these measurements.
