FCW Limited Warning
If the instrument cluster displays “ACC/FCW
Limited Functionality” or “ACC/FCW Limited
Functionality Clean Front Windshield”
momentarily, there may be a condition that limits
FCW functionality. Although the vehicle is still
drivable under normal conditions, the active
braking may not be fully available. Once the
condition that limited the system performance is
no longer present, the system will return to its full
performance state. If the problem persists, see an
authorized dealer.
Service FCW Warning
If the system turns off, and the instrument cluster
displays:
ACC/FCW Unavailable Service Required
Cruise/FCW Unavailable Service Required
This indicates there is an internal system fault.
Although the vehicle is still drivable under normal
conditions, have the system checked by an
authorized dealer.
Pedestrian Emergency Braking (PEB) —
If Equipped
PEB is a subsystem of the Forward Collision
Warning (FCW) system which provides the driver
with audible warnings and visual warnings, in the
instrument cluster display. It may apply limited automatic braking when it detects a potential
frontal collision with a pedestrian/cyclist.
If a PEB event begins at a speed below 39 mph
(62 km/h), the system may provide maximum
braking to mitigate the potential collision with a
pedestrian/cyclist. If the PEB event stops the
vehicle completely, the system will hold the vehicle
at a standstill for two seconds and then release the
brakes. When the system determines a collision
with the pedestrian/cyclist in front of you is no
longer probable, the warning message will be
deactivated.
The minimum speed for PEB activation is 3 mph
(5 km/h).
Turning PEB On Or OffNOTE:The default status of PEB is “On.” This allows the
system to warn you of a possible frontal collision
with the pedestrian.The PEB button is located in the Uconnect display
in the Control settings Ú
page 199.
To turn the PEB system off, push the Pedestrian
Emergency Braking button.
To turn the PEB system back on, push the Warning
Active Braking button.
Changing the PEB status to “Off” deactivates the
system, so no warning or active braking will be
available in case of a possible frontal collision with
the pedestrian/cyclist.
NOTE:The PEB system will retain the last setting selected
by the driver after ignition shut down. The system
will not reset to the default setting when the
vehicle is restarted.
TIRE PRESSURE MONITORING SYSTEM
(TPMS)
(Vehicles Under 10K Gross Vehicle Weight Rating
(GVWR) Only)
The Tire Pressure Monitoring System (TPMS) will
warn the driver of a low tire pressure based on the
vehicle recommended cold placard pressure.
NOTE:The TPMS Warning Light will illuminate in the
instrument cluster and a chime will sound when
tire pressure is low in one or more of the four active
road tires. In addition, the instrument cluster will
display a graphic showing the pressure values of
WARNING!
Pedestrian Emergency Braking (PEB) is not
intended to avoid a collision on its own, nor can
PEB detect every type of potential collision with
a pedestrian. The driver has the responsibility to
avoid a collision by controlling the vehicle via
braking and steering. Failure to follow this
warning could lead to serious injury or death.

23_DPF_OM_EN_USC_t.book Page 280

282SAFETY
NOTE:
The TPMS is not intended to replace normal tire
care and maintenance or to provide warning of
a tire failure or condition.
If your vehicle is not equipped with the Tire Fill
Alert feature the TPMS should not be used as a
tire pressure gauge while adjusting your tire
pressure.
Driving on a significantly underinflated tire
causes the tire to overheat and can lead to tire
failure. Underinflation also reduces fuel effi -
ciency and tire tread life, and may affect the
vehicle’s handling and stopping ability.
The TPMS is not a substitute for proper tire
maintenance, and it is the driver’s responsibility
to maintain correct tire pressure using an accu -
rate tire pressure gauge, even if underinflation
has not reached the level to trigger illumination
of the TPMS Warning Light.
Seasonal temperature changes will affect tire
pressure, and the TPMS will monitor the actual
tire pressure in the tire.
Example: Tire Pressure Monitoring System Display

The Tire Pressure Monitoring System (TPMS) uses
wireless technology with wheel rim mounted
electronic sensors to monitor tire pressure levels.
Sensors, mounted to each wheel as part of the
valve stem, transmit tire pressure readings to the
receiver module.
NOTE:It is particularly important for you to check the tire
pressure in all of the tires on your vehicle monthly
and to maintain the proper pressure.
The TPMS consists of the following components:
Receiver module
Four Tire Pressure Monitoring System sensors
Various Tire Pressure Monitoring System
messages, which display in the instrument
cluster
Tire Pressure Monitoring System Warning Light
Tire Pressure Monitoring System Low
Pressure Warnings
The Tire Pressure Monitoring System
Warning Light will illuminate in the
instrument cluster when tire pressure is
low in one or more of the four active road
tires. The instrument cluster will display a graphic
showing the pressure values of each tire with the
low tire pressure values in a different color. An
"Inflate to XX" message will also be displayed.

Example: Low Tire Pressure Display

Should this occur, you should stop as soon as
possible and inflate the tires with a low pressure
condition (those in a different color in the
instrument cluster graphic) to the vehicle’s
recommended cold placard pressure inflation
value shown in the "Inflate to XX" message. Once
the system receives the updated tire pressures,
the system will automatically update, the graphic

The SABs (if equipped with SABs) may help to
reduce the risk of occupant injury during certain
side impacts, in addition to the injury reduction
potential provided by the seat belts and body
structure.
When the SAB deploys, it opens the seam on the
outboard side of the seatback’s trim cover. The
inflating SAB deploys through the seat seam into
the space between the occupant and the door. The
SAB moves at a very high speed and with such a
high force that it could injure occupants if they are
not seated properly, or if items are positioned in
the area where the SAB inflates. Children are at an
even greater risk of injury from a deploying air bag.
Supplemental Side Air Bag Inflatable Curtains
(SABICs) — If Equipped
Your vehicle may be equipped with Supplemental
Side Air Bag Inflatable Curtains (SABICs). If your
vehicle is equipped with Supplemental Side Air Bag
Inflatable Curtains (SABICs), please refer to the
information below. Supplemental Side Air Bag Inflatable Curtains
(SABICs) are located above the side windows. The
trim covering the SABICs is labeled “SRS AIRBAG”
or “AIRBAG.”

Supplemental Side Air Bag Inflatable Curtain (SABIC) Label Location

SABICs (if equipped with SABICs) may help reduce
the risk of head and other injuries to front and rear
seat outboard occupants in certain side impacts,
in addition to the injury reduction potential
provided by the seat belts and body structure.
The SABIC deploys downward, covering the side
windows. An inflating SABIC pushes the outside
edge of the headliner out of the way and covers the
window. The SABICs inflate with enough force to
injure occupants if they are not belted and seated
properly, or if items are positioned in the area
where the SABICs inflate. Children are at an even
greater risk of injury from a deploying air bag. The SABICs (if equipped with SABICs) may help
reduce the risk of partial or complete ejection of
vehicle occupants through side windows in certain
side impact events.
Side Impacts
The Side Air Bags are designed to activate in
certain side impacts. The Occupant Restraint
Controller (ORC) determines whether the
deployment of the Side Air Bags in a particular
impact event is appropriate, based on the severity
and type of collision. The side impact sensors aid
the ORC in determining the appropriate response
WARNING!
Do not use accessory seat covers or place
objects between you and the Side Air Bags; the
performance could be adversely affected and/or
objects could be pushed into you, causing
serious injury.
WARNING!
Do not mount equipment, or stack luggage or
other cargo up high enough to block the
deployment of the SABICs. The trim covering
above the side windows where the SABIC and
its deployment path are located should
remain free from any obstructions.
In order for the SABICs to work as intended, do
not install any accessory items in your vehicle
which could alter the roof. Do not add an after
-
market sunroof to your vehicle. Do not add
roof racks that require permanent attach -
ments (bolts or screws) for installation on the
vehicle roof. Do not drill into the roof of the
vehicle for any reason.

Air Bag System Components
NOTE:The Occupant Restraint Controller (ORC) monitors
the internal circuits and interconnecting wiring
associated with electrical Air Bag System Compo -
nents listed below:
Occupant Restraint Controller (ORC)
Air Bag Warning Light
Steering Wheel and Column
Instrument Panel
Knee Impact Bolsters
Driver and Front Passenger Air Bags
Seat Belt Buckle Switch
Supplemental Side Air Bags — If Equipped
Front and Side Impact Sensors — If Equipped
Seat Belt Pretensioners — If Equipped
If A Deployment Occurs
The front air bags are designed to deflate
immediately after deployment.
NOTE:Front and/or side air bags will not deploy in all colli -
sions. This does not mean something is wrong with
the air bag system. If you do have a collision which deploys the air
bags, any or all of the following may occur:
The air bag material may sometimes cause
abrasions and/or skin reddening to the occu
-
pants as the air bags deploy and unfold. The
abrasions are similar to friction rope burns or
those you might get sliding along a carpet or
gymnasium floor. They are not caused by
contact with chemicals. They are not permanent
and normally heal quickly. However, if you
haven’t healed significantly within a few days, or
if you have any blistering, see your doctor imme -
diately.
As the air bags deflate, you may see some
smoke-like particles. The particles are a normal
by-product of the process that generates the
non-toxic gas used for air bag inflation. These
airborne particles may irritate the skin, eyes,
nose, or throat. If you have skin or eye irritation,
rinse the area with cool water. For nose or throat
irritation, move to fresh air. If the irritation
continues, see your doctor. If these particles
settle on your clothing, follow the garment
manufacturer’s instructions for cleaning.
Do not drive your vehicle after the air bags have
deployed. If you are involved in another collision,
the air bags will not be in place to protect you.
NOTE:
Air bag covers may not be obvious in the interior
trim, but they will open during air bag deploy -
ment.
After any collision, the vehicle should be taken
to an authorized dealer immediately.
Enhanced Accident Response System
In the event of an impact, if the communication
network remains intact, and the power remains
intact, depending on the nature of the event, the
ORC will determine whether to have the Enhanced
Accident Response System perform the following
functions:
Cut off fuel to the engine (if equipped).
Cut off battery power to the electric motor
(if equipped).
Flash hazard lights as long as the battery has
power.
WARNING!
Deployed air bags and seat belt pretensioners
cannot protect you in another collision. Have the
air bags, seat belt pretensioners, and the seat
belt retractor assemblies replaced by an
authorized dealer immediately. Also, have the
Occupant Restraint Controller System serviced
as well.

NOTE:After an accident, remember to cycle the ignition to
the STOP (OFF/LOCK) position and remove the key
from the ignition switch to avoid draining the
battery. Carefully check the vehicle for fuel leaks in
the engine compartment and on the ground near
the engine compartment and fuel tank before
resetting the system and starting the engine. If
there are no fuel leaks or damage to the vehicle
electrical devices (e.g. headlights) after an
accident, reset the system by following the
procedure described below. If you have any doubt,
contact an authorized dealer.
Enhanced Accident Response System
Reset Procedure
In order to reset the Enhanced Accident Response
System functions after an event, the ignition switch
must be changed from ignition START or ON/RUN
to ignition OFF. Carefully check the vehicle for fuel
leaks in the engine compartment and on the
ground near the engine compartment and fuel
tank before resetting the system and starting the
engine. After an accident, if the vehicle will not start after
performing the reset procedure, the vehicle must
be towed to an authorized dealer to be inspected
and to have the Enhanced Accident Response
System reset.
Maintaining Your Air Bag System
WARNING!
Modifications to any part of the air bag system
could cause it to fail when you need it. You
could be injured if the air bag system is not
there to protect you. Do not modify the compo
-
nents or wiring, including adding any kind of
badges or stickers to the steering wheel hub
trim cover or the upper passenger side of the
instrument panel. Do not modify the front

Dual Rear Wheels
Slots in the wheels will assist in properly orienting
the inner and outer wheels. Align these slots when
assembling the wheels for best access to the tire
valve on the inner wheel. The tires of both dual
wheels must be completely off the ground when
tightening to ensure wheel centering and
maximum wheel clamping.
Dual wheel models require a special heavy-duty lug
nut tightening adapter (included with the vehicle)
to correctly tighten the lug nuts. Also, when it is
necessary to remove and install dual rear wheels,
use a proper vehicle lifting device.
NOTE:When installing a spare tire (if equipped) as part of
a dual rear wheel end combination, the tire
diameter of the two individual tires must be
compared. If there is a significant difference, the
larger tire should be installed in a front location.
The correct direction of rotation for dual tire instal -
lations must also be observed.
It is recommended that wheel stud nuts be kept
torqued to specifications at all times. Torque wheel
stud nuts to specifications at each lubrication
interval Ú page 411.
Wheel Nuts
All wheel nuts should be tightened occasionally to
eliminate the possibility of wheel studs being
sheared or the bolt holes in the wheels becoming elongated. This is especially important during the
first few hundred miles/kilometers of operation to
allow the wheel nuts to become properly set. All
wheel nuts should first be firmly seated against the
wheel. The wheel nuts should then be tightened to
recommended torque. Tighten the wheel nuts to
final torque in increments. Progress around the
bolt circle, tightening the wheel nut opposite to the
wheel nut just previously tightened until final
torque is achieved Ú

F EQUIPPED
Refer to Upfitters Body Builder’s Guide for
information on stowing your spare tire (if
equipped).
HUB CAPS/WHEEL COVERS —
I
F EQUIPPED
The hub caps must be removed before raising the
vehicle off the ground. For 3500 Single Rear-Wheel (SRW) models, use
the flat end of the lug wrench to hook and pull off
the hub cap. Find the opening in the hub cap,
insert the lug wrench, and pull off the cap. If you
need to pry against the wheel, protect the wheel
surface.

Lug Wrench Insertion Location — Hub Cap

On 3500 models with Dual Rear-Wheels (DRW),
you must first remove the hub caps—use the
procedure noted for the single rear wheel. For the
wheel covers (wheel skins), insert the flat end of
the lug wrench between the outer edge of the
wheel cover and the wheel. Pry against the wheel
to remove the wheel cover. Repeat this procedure
around the wheel until the cover pops off.
CAUTION!
Use extreme caution when removing the front
and rear wheel covers. Damage can occur to the
center cap and/or the wheel if screwdriver type
tools are used. A pulling motion, not a pry off
motion, is recommended to remove the caps.
