To help avoid personal injury, keep hands
and feet away from wheel housing area, and
stay away from under the vehicle when
lowering the vehicle chassis.
Your vehicle adjusts its ride height
automatically to increase vehicle safety and
to reduce fuel consumption.
The vehicle chassis ride height is raised or
lowered according to the selected level
setting and to the vehicle speed. With
increasing speed, the ride height is reduced
by up to approximately 0.4 in (10 mm). With
decreasing speed, the ride height is again
raised to the selected vehicle level.
These height adjustments are so small that
you may not notice any change.
