Trim height refers to the distance from the bottom of the vehicle's body (3) to the ground (4). Several factors can influence what a vehicle's trim height will be at any given time: tire inflation, additional weight in the vehicle, the condition of the struts and springs after the vehicle has accumulated some mileage, and non-original tire brand size can all affect trim height.

Before measuring trim height, perform the following steps:

    • Make sure all tires are properly inflated.
    • Remove all extra weight from the vehicle.
    • Bounce the front and rear of the vehicle up and down a few times to stabilize the suspension.
    • Make sure the fuel tank is at least 1/2 full.
    • Securely fasten the spare tire and jack within the rear luggage compartment.
    • Close hood and all doors.
    • Measure the vehicle body-to-ground clearance several times. The true trim height should be an average of several measurements. Refer to Trim Height Specifications .
