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.
This feature can be activated through the Ucon -
nect system.
Refer to “Uconnect Settings” in “Multimedia”
for further information.
Jack Location
The jack and jack tools are stored under the
front passenger seat.
Removal Of Jack And Tools
To access the jack and jack tools, you must
remove the plastic access cover located on the
side of the front passenger’s seat. To remove
the cover, pull the front part of the cover
(closest to the front of the seat) toward you to
release a locking tab. Once the front of the
cover is loose, slide the cover toward the front
of the seat until it is free from the seat frame.
Jack Access Cover
Remove the jack and tools by turning the wing
bolt counterclockwise, remove the wing bolt
and then slide the assembly out from under the
seat.
Wing Bolt/Jack And Tools
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.

3. Pull the spare tire out from under the vehicle to gain access to the spare tire
retainer.
Pulling The Spare Tire Out
WARNING!
After using the jack and tools, always reinstall
them in the original carrier and location.
While driving you may experience abrupt
stopping, rapid acceleration or sharp turns. A
loose jack, tools, bracket or other objects in
the vehicle may move around with force,
resulting in serious injury.

NOTE:
The winch mechanism is designed for use with
the extension tubes only. Use of an air wrench
or other power tools is not recommended and
can damage the winch.
Preparations For Jacking
1. Park the vehicle on a firm, level surface.
Avoid ice or slippery areas.
2. Turn on the Hazard Warning Flashers.
3. Apply the parking brake.
4. Shift the transmission into Park (P).
5. Turn the ignition OFF. 6. Block both the front and rear of the wheel
diagonally opposite the jacking position. For
example, if the driver’s front wheel is being
changed, block the passenger’s rear wheel.
Wheel Blocked
NOTE:
Passengers should not remain in the vehicle
when the vehicle is being raised or lifted.
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 being hit when
operating the jack or changing the wheel.

Jacking Instructions
Jack Warning Label Lug Wrench Adapter Shown In Jack And Tools Assembly
1. Remove the spare wheel, jack, and tools
from storage.
2. Using the lug wrench, loosen, but do not remove, the wheel nuts by turning them
counterclockwise one turn while the wheel
is still on the ground. Changing a dually tire
requires the lug wrench adapter.
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 Flashers.
Apply the parking brake firmly and set the
transmission in PARK.
Block the wheel diagonally opposite the
wheel to be raised.
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.
If working on or near a roadway, be
extremely careful of motor traffic.
To assure that spare tires, flat or inflated,
are securely stowed, spares must be
stowed with the valve stem facing the
ground.
WARNING! (Continued)
CAUTION!
Do not attempt to raise the vehicle by jacking
on locations other than those indicated in the
Jacking Instructions for this vehicle.

3. Placement of the jack is critical:
Jack / Extensions Placement
Front Jacking Location
When changing the front wheel, assemble
the jack driver to the jack and connect the
jack driver to the extension tubes. Place the
jack under the axle as close to the tire as
possible with the drive tubes extending to
the front. Connect the extension tubes and
lug wrench.
Front Lifting Point
Front Jacking Location
Rear Jacking Location
When changing a rear wheel, assemble the
jack driver to the jack and connect the jack
driver to the extension tubes. Place the jack
20_DJD2_OM_EN_USC_t.book Page 348
Page 351 of 553

IN CASE OF EMERGENCY349
under the axle between the spring and the
shock absorber with the extension tubes ex -
tending to the rear.
Rear Lifting Point
Rear Jacking Location
Connect the extension tubes and lug
wrench. NOTE:
If the bottle jack will not lower by turning the dial
(thumbwheel) by hand, it may be necessary to
use the jack driver in order to lower the jack.
4. By rotating the lug wrench clockwise, raise
the vehicle until the wheel just clears the
surface.
5. Remove the lug nuts and pull the wheel off. On Single Rear Wheel (SRW) trucks, install
the spare wheel and lug nuts with the cone
shaped end of the wheel nuts toward the
wheel. On 3500 Dual Rear Wheel models
(DRW) trucks, if the outer tire is being replaced then leave the inner wheel on the
vehicle. If the inner wheel is being replaced
remove the outer wheel and replace the
inner wheel. The wheel nuts are a two-piece
assembly with a flat face. Lightly tighten the
lug nuts. To avoid the risk of forcing the
vehicle off the jack, do not fully tighten the
lug nuts until the vehicle has been lowered.
Rear Inner Wheel Proper Placement (Dual Rear Wheel Equipped)
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.
WARNING!
Raising the vehicle higher than necessary can
make the vehicle less stable. It could slip off
the jack and hurt someone near it. Raise the
vehicle only enough to remove the tire.

6. Finish tightening the lug nuts. Push down on the lug wrench while at the end of the handle
for increased leverage. Tighten the lug nuts in
a star pattern until each nut has been tight -
ened twice. For the correct lug nut torque refer
to “Wheel And Tire Torque Specifications” in
“Technical Specifications”. If in doubt about
the correct tightness, have them checked with
a torque wrench by an authorized dealer or
service station. 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. Stow the replaced tire, jack, and tools as
previously described.
NOTE:
The bottle jack will not lower by turning the dial
(thumbwheel) by hand, it may be necessary to
use the jack driver in order to lower the jack.
9. Adjust the tire pressure when possible.
NOTE:
Do not oil wheel studs. For chrome wheels, do
not substitute with chrome plated lug nuts.
To Stow The Flat Or Spare
NOTE:
Have the flat tire repaired or replaced immedi -
ately.
1. Turn the wheel so that the valve stem is facing the ground and toward the rear of
the vehicle for convenience in checking the
spare tire inflation. Slide the wheel retainer
through the center of the wheel.
Reinstalling The Retainer
WARNING!
A loose tire or jack thrown forward in a
collision or hard stop, could endanger the
occupants of the vehicle. Always stow the jack
parts and the spare tire in the places
provided.
WARNING!
A loose tire or jack thrown forward in a
