roads in fair or better conditionCompared to the highway level, the vehicle
level changes by
+ 1.97 in (+ 50 mm) in raised level
+/- 0 in (+ 0 mm) in highway level

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-

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.!Please also note the information in the
