G Warning!
To help avoid personal injury, keep hands
and feet away from wheel housing area, and
stay away from under the vehicle when low-
ering the vehicle chassis.
Your vehicle adjusts its ride height automati-
cally to increase vehicle safety and to reduce
fuel consumption.
The vehicle chassis ride height is raised or
lowered according to the selected level set-
ting and to the vehicle speed. With increasing
speed, the ride height is reduced by up to
approximately 0.5 in (12 mm). With decreas-
ing 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.
