squeeze the manual brake control lever completely.
9. If the trailer wheels lockup (indicated by squealing tires), reduce the GAIN setting; if the trailer wheels turn
freely, increase the GAIN setting.

WARNING!(Continued)
•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 suspension
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 instrument cluster
display. Refer to “Instrument Cluster Display” in “Under-
standing Your Instrument Panel” for further information.
Jack Location
The jack and jack tools are stored under the front passenger
seat.

winch.Preparations
1. Park the vehicle on a firm, level surface. Avoid ice or slippery areas.
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.
2. Turn on the Hazard Warning flasher.
3. Apply the parking brake.
4. Place the gear selector into PARK. On four-wheel drive vehicles, shift the transfer case to the 4L position.
5. Turn the ignition OFF.
Block both the front and rear of the wheel diagonally
opposite the jacking position. For example, if the right front
wheel is being changed, block the left rear wheel. NOTE:Passengers should not remain in the

WARNING!
Carefully follow these tire changing warnings to help
prevent personal injury or damage to your vehicle:
•Always park on a firm, level surface as far from the
edge of the roadway as possible before raising the
vehicle.
• Turn on the Hazard Warning flasher.
• Block the wheel diagonally opposite the wheel to be
raised.
• Set the parking brake firmly and set an automatic
transmission in PARK; a manual transmission in
REVERSE.
• Never start or run the engine with the vehicle on a
jack.
• Do not let anyone sit in the vehicle when it is on a
jack.
• Do not get under the vehicle when it 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.
• Only use the jack in the positions indicated and for
lifting this vehicle during a tire change.
(Continued)

Connect the jack tube extension and wheel wrench.
CAUTION!
Before raising the wheel off the ground, make sure that
the jack will not damage surrounding truck parts and
adjust the jack position as required.
4. By rotating the lug wrench clockwise, raise the vehicle until the wheel just clears the surface.
WARNING!
Raising the vehicle higher than necessary can make the
vehicle unstable. It could slip off the jack and hurt
someone near it. Raise the vehicle only enough to
remove the tire.
5. Remove the wheel nuts and pull the wheel off. Install the spare wheel and wheel nuts with the cone shaped
end of the wheel nuts toward the wheel. To avoid the
risk of forcing the vehicle off the jack, do not fully
tighten the wheel nuts until the vehicle has been low-
ered. 6. Finish tightening the lug nuts. Push down on the
wrench while at the end of the handle for increased
leverage. Tighten the lug nuts in a star pattern until each
nut has been tightened twice. For the correct lug nut
torque refer to “Torque Specifications” in this section. If
in doubt about the correct tightness, have them checked
with a torque wrench by you authorized dealer or
service station.
WARNING!
A loose tire or jack thrown forward in a collision or
hard stop could injure someone in the vehicle. Always
stow the jack parts and the extra tire and wheel in the
places provided.
7. Install the wheel center cap and remove the wheel blocks. Do not install chrome or aluminum wheel center
caps on the spare wheel. This may result in cap damage.
8. Lower the jack to its fully closed position. If the bottle jack will not lower by turning the dial (thumbwheel) by
hand, it may be necessary to use the jack drive tube in
order to lower the jack. Stow the replaced tire, jack, and
tools as previously described.
