JACKING AND TIRE CHANGING
Jacking And Tire Changing 1500 Series Trucks
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.
(Continued)
WARNING! (Continued)
•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.
