WARNING!(Continued)
•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 slippery areas.
NOTE:If your vehicle is equipped with an air suspen-
sion system, there is a feature which allows the automatic
leveling to be disabled to assist with changing a tire.
If your vehicle is equipped with a touchscreen, this
feature can be activated through the Uconnect® system.
Refer to “Uconnect® Settings” in “Understanding Your
Instrument Panel” for further information.
If your vehicle is not equipped with a touchscreen, this
feature can be activated through the Electronic Vehicle
Information Center (EVIC) or Driver Information Display
(DID). Refer to “Electronic Vehicle Information Center
(EVIC)” or “Driver Information Display (DID)” in “Un-
derstanding Your Instrument Panel” for further informa-
tion.
