Ford Expedition 2018 Owner's Manual page 212

Four-Wheel Drive
(If Equipped)
We recommend that you use caution when
your vehicle has either a high load or
device, such as ladders or luggage racks.
Any modifications to your vehicle that raise
the center of gravity may cause your
vehicle to roll over when there is a loss of
vehicle control.
Failure to maintain your vehicle correctly
may void the warranty, increase your repair
cost, reduce vehicle performance and
operational capabilities and adversely
affect you and your passenger's safety. We
recommend you frequently inspect your
vehicle's chassis components when your
vehicle is subject to off road usage.
