JACKING AND TIRE CHANGING NOTE:
If your vehicle is equipped with an air suspension system,
there is a feature which allows the automatic leveling to be
disabled to assist with changing a tire.
This feature can be activated through the Uconnect system.
Refer to “Uconnect Settings” in “Multimedia” for further
information.
WARNING!
• Do not attempt to change a tire on the side of the vehicle close to moving traffic. Pull far enough off the road to
avoid the danger of being hit when operating the jack
or changing the wheel.
• Being under a jacked-up vehicle is dangerous. The vehicle could slip off the jack and fall on you. You
could be crushed. Never put any part of your body
under a vehicle that is on a jack. If you need to get
under a raised vehicle, take it to a service center where
it can be raised on a lift.
• Never start or run the engine while the vehicle is on a jack.
• The jack is designed to be used as a tool for changing tires only. The jack should not be used to lift the
vehicle for service purposes. The vehicle should be
jacked on a firm level surface only. Avoid ice or slip -
pery areas.
