Riding Height Adjustment

NOTE: On vehicles with electronic chassis controls, ensure all systems are functional before adjusting riding height or wheel alignment.

Before adjusting alignment, check riding height. Check riding height with vehicle on level floor and tires properly inflated. Tire inflation specifications can be found on door pillar, side wall of tire, sun visor or glove box. Bounce vehicle several times and allow suspension to settle.

Visually inspect vehicle for signs of abnormal height from front to rear or side to side. Remove extra heavy items from passenger and luggage compartments. If riding height is not within specifications, check, repair or replace suspension components. See RIDING HEIGHT SPECIFICATIONS table. See Fig 1 .
