Check the vehicle condition when operating to the standard vehicle height setting.

• Perform the work with the vehicle stopped on a flat surface.
• Make sure the hood is closed.
• Make sure the luggage compartment door closed
• Set the shift lever to P.
• Make sure the courtesy lights are not on.
• Do not depress the brake pedal.
• Perform height adjust from outside of the vehicle to avoid vehicle height changes due when getting out of the vehicle.

2. Get out of the vehicle and bounce the vehicle up and down at the corners to stabilize the suspension.
3. From the outside of the vehicle, select access mode and turn it off via the vehicle setting conditions on the multi-information display.
4. Operate the height control switch from outside the vehicle and adjust the vehicle height to HIGH
5. After vehicle height control is completed, operate the height control switch from outside the vehicle and return the vehicle height to NORMAL.
6. After vehicle height control is completed, select vehicle height control mode and turn it off via the vehicle setting conditions on the multi-information display.

1. Bounce the vehicle up and down at the corners to stabilize the suspension.

   1. C: Ground clearance of rear wheel center
   1. D: Ground clearance of rear suspension arm attachment recess

   Vehicle Height (Unloaded Vehicle)

   Item	Front A - B	Rear C - D
   w/ Air suspension	132 mm (5.20 in.)	88 mm (3.46 in.)
   w/o Air suspension	116 mm (4.57 in.)	71 mm (2.80 in.)

Camber (Unloaded Vehicle)

Caster (Unloaded Vehicle)

Steering Axis Inclination (Unloaded Vehicle)

1. Bounce the vehicle up and down at the corners to stabilize the suspension.
2. Release the parking brake and move the shift lever to N.
3. Push the vehicle straight ahead approximately 5 m (16.4 ft.). (Step C)
4. Put tread center marks on the rearmost points of the front wheels and measure the distance between the marks (dimension B).

   *a	Tread Center Mark
   *b	Dimension B
   	Front of the Vehicle

5. Slowly push the vehicle straight ahead to cause the front wheels to rotate 180°. Use the front tire valve as a reference point.

   HINT: 

   Do not allow the wheels to rotate more than 180°. If the wheels rotate more than 180°, perform the procedure from step C again.

6. Measure the distance between the tread center marks on the front of the wheels (dimension A).
