JACKING INSTRUCTIONS
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.
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.

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.
