Keep in mind that in rough or uneven
roads, adjusting the vehicle to a lower
level may cause the vehicle underbody
to come in contact with the road and
result in damage to the vehicle under-
body. Always make sure the vehicle
has sufficient ground clearance before
adjusting it to a lower level.

Before jacking up the vehicle with
equipment that lifts one or more of the
wheels completely off the ground,
remove the SmartKey from the starter
switch.
