4. Press ESP button four times within twenty seconds.
The “ESP/TCS Indicator Light” should appear and dis-
appear four times.
5. Rotate the steering wheel 360° clockwise (180° clock-
wise from center).
6. Cycle ignition switch OFF then ON.
7. If the sequence was completed properly, the “ESP/
TCS Indicator Light” will blink several times to confirm
HSA is off.
Steps 1-7 must be completed within 90 seconds to turn off
HSA. Repeat steps 1-7 to re-enable HSA functionality.Electronic Roll Mitigation (ERM)The ERM system anticipates the potential for wheel lift
by monitoring the driver ’s steering wheel input and the
speed of the vehicle. When ERM determines that the rate
of change of the steering wheel angle and vehicle speed
are sufficient to potentially cause wheel lift, it applies theappropriate brake and may reduce engine power to
lessen the chance that wheel lift will occur. ERM will only
intervene during very severe or evasive driving maneu-
vers.
ERM can only reduce the chance of wheel lift occurring
during severe or evasive driving maneuvers. It cannot
prevent wheel lift due to other factors such as road
conditions, leaving the roadway or striking objects or
other vehicles.
WARNING!
Many factors, such as vehicle loading, road condi-
tions and driving conditions, influence the chance
that wheel lift or rollover may occur.

Removing The Spare TireRemove the spare tire before attempting to jack the truck.
Attach the wheel wrench to the jack extension tube. Insert
the tube through the access hole between the lower
tailgate and the top of the bumper and into the winch
mechanism tube. Rotate the wheel wrench handle coun-
terclockwise until the spare tire is on the ground with
enough cable slack to allow you to pull it out from under
the vehicle. When the spare is clear, tilt the retainer at the
end of the cable and pull it through the center of the
wheel.
NOTE:Always stow the spare tire with the valve stem
facing the ground.
It is recommended that you stow the flat or spare to
avoid tangling the loose cable.

WARNING! (Continued)
•
Do not get under the vehicle when it is on a jack.
•
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.
•
Turn on the Hazard Warning flasher.
1. Remove the spare wheel, jack, and tools from storage. 2. Using the wheel wrench, loosen, but do not remove,
the wheel nuts by turning them counterclockwise one
turn while the wheel is still on the ground.
3. Placement of the Jack:
•
For 2500/3500 4x2 series trucks, when changing a
front wheel, place the bottle jack under the frame
rail behind the wheel. Locate the jack as far forward
as possible on the straight part of the frame.

•
Connect the jack tube extension and wheel wrench.
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.NOTE:
If the 2500/3500 bottle jack will not lower by
turning the dial (thumbwheel) by hand, it may be neces-
sary to use the jack drive tube in order to lower the jack.
4. By rotating the wheel wrench clockwise, raise the
vehicle until the wheel just clears the surface.
WARNING!
Raising the vehicle higher than necessary can make
the vehicle unstable and cause an accident. 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 nuts toward the wheel on 2500/3500 single rear-
wheel (SRW) models. On 3500 dual rear-wheel models
(DRW) the lug nuts are a two-piece assembly with a flat
