Rear Axle Locker Fault Warning Light —
If Equipped
This warning light will illuminate to indicate
when a rear axle locker fault has been
detected.
Service Forward Collision Warning (FCW)
Light — If Equipped
This warning light will illuminate to indicate a
fault in the FCW System. Contact an authorized
dealer for service
Úpage 274.
Service Stop/Start System Warning Light —
If Equipped
This warning light will illuminate when the
Stop/Start system is not functioning properly
and service is required. Contact an authorized
dealer for service.
Service 4WD Warning Light — If Equipped
This warning light will illuminate to signal a fault
with the 4WD system. If the light stays on or
comes on during driving, it means that the 4WD
system is not functioning properly and that
service is required. We recommend you drive to the
nearest service center and have the vehicle serviced
immediately.
Cruise Control Fault Warning Light
This warning light will illuminate to indicate the
Cruise Control System is not functioning
properly and service is required. Contact an
authorized dealer.
Tire Pressure Monitoring System (TPMS)
Warning Light
The warning light switches on and a message is
displayed to indicate that the tire pressure is
lower than the recommended value and/or
that slow pressure loss is occurring. In these
cases, optimal tire duration and fuel consumption may not
be guaranteed.
Should one or more tires be in the condition previously
mentioned, the display will show the indications
corresponding to each tire. Each tire, including the spare (if provided), should be
checked monthly when cold and inflated to the inflation
pressure recommended by the vehicle manufacturer on
the vehicle placard or tire inflation pressure label. If your
vehicle has tires of a different size than the size indicated
on the vehicle placard or tire inflation pressure label, you
should determine the proper tire inflation pressure for
those tires.
As an added safety feature, your vehicle has been
equipped with a TPMS that illuminates a low tire pressure
telltale when one or more of your tires is significantly
underinflated. Accordingly, when the low tire pressure
telltale illuminates, you should stop and check your tires
as soon as possible, and inflate them to the proper
pressure. Driving on a significantly underinflated tire
causes the tire to overheat and can lead to tire failure.
Underinflation also reduces fuel efficiency and tire tread
life, and may affect the vehicle’s handling and stopping
ability.
Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver’s responsibility to
maintain correct tire pressure, even if underinflation has
not reached the level to trigger illumination of the TPMS
low tire pressure telltale.
CAUTION!
Prolonged driving with the Malfunction Indicator Light
(MIL) on could cause damage to the vehicle control
system. It also could affect fuel economy and
driveability. If the MIL is flashing, severe catalytic
converter damage and power loss will soon occur.
Immediate service is required.
CAUTION!
Do not continue driving with one or more flat tires as
handling may be compromised. Stop the vehicle,
avoiding sharp braking and steering. If a tire puncture
occurs, repair immediately using the dedicated tire
repair kit and contact an authorized dealer as soon as
possible.

EMISSIONS INSPECTION AND
MAINTENANCE PROGRAMS
In some localities, it may be a legal requirement to pass an
inspection of your vehicle's emissions control system.
Failure to pass could prevent vehicle registration.
For states that require an Inspection and
Maintenance (I/M), this check verifies the
Malfunction Indicator Light (MIL) is functioning
and is not on when the engine is running, and
that the OBD II system is ready for testing.
Normally, the OBD II system will be ready. The OBD II
system may not be ready if your vehicle was recently
serviced, recently had a depleted battery or a battery
replacement. If the OBD II system should be determined
not ready for the I/M test, your vehicle may fail the test. Your vehicle has a simple ignition actuated test, which you
can use prior to going to the test station. To check if your
vehicle's OBD II system is ready, you must do the following:

1. Cycle the ignition switch to the ON position, but do
not crank or start the engine.

NOTE:If you crank or start the engine, you will have to start this
test over.
2. As soon as you cycle the ignition switch to the ON position, you will see the Malfunction Indicator Light
(MIL) symbol come on as part of a normal bulb check.
3. Approximately 15 seconds later, one of two things will happen:
 The MIL will flash for about 10 seconds and then
return to being fully illuminated until you turn OFF
the ignition or start the engine. This means that
your vehicle's OBD II system is not ready and you
should not proceed to the I/M station.
 The MIL will not flash at all and will remain fully illu -
minated until you place the ignition in the off posi -
tion or start the engine. This means that your
vehicle's OBD II system is ready and you can
proceed to the I/M station. If your OBD II system is
not ready, you should see an
authorized dealer or repair facility. If your vehicle was
recently serviced or had a battery failure or replacement,
you may need to do nothing more than drive your vehicle
as you normally would in order for your OBD II system to
update. A recheck with the approved test routine may then
indicate that the system is now ready.
Regardless of whether your vehicle's OBD II system is
ready or not, if the MIL is illuminated during normal vehicle
operation you should have your vehicle serviced before
going to the I/M station. The I/M station can fail your
vehicle because the MIL is on with the engine running.

150STARTING AND OPERATING
Display Warnings And Maintenance
“WIPE FRONT RADAR SENSOR IN FRONT OF
VEHICLE” WARNING
The “ACC/FCW Unavailable Wipe Front Radar Sensor”
warning will display and a chime will sound when
conditions temporarily limit system performance.
This most often occurs at times of poor visibility, such as
in snow or heavy rain. The ACC system may also become
temporarily blinded due to obstructions, such as mud, dirt
or ice. In these cases, the instrument cluster display will
display “ACC/FCW Unavailable Wipe Front Radar Sensor”
and the system will deactivate.
The “ACC/FCW Unavailable Wipe Front Radar Sensor”
message can sometimes be displayed while driving in
highly reflective areas (i.e. ice and snow, or tunnels with
reflective tiles). The ACC system will recover after the
vehicle has left these areas. Under rare conditions, when
the radar is not tracking any vehicles or objects in its path
this warning may temporarily occur.
NOTE:If the “ACC/FCW Unavailable Wipe Front Radar Sensor”
warning is active, Fixed Speed Cruise Control is still
available.
If weather conditions are not a factor, the driver should
examine the sensor. It may require cleaning or removal of
an obstruction. The sensor is located in the camera in the
center of the windshield, on the forward side of the
rearview mirror. To keep the ACC system operating properly, it is important
to note the following maintenance items:

Always keep the sensor clean. Carefully clear the wind-
shield.
 Do not remove any screws from the sensor. Doing so
could cause an ACC system malfunction or failure and
require a sensor realignment.
 Do not attach or install any accessories near the
sensor, including transparent material. Doing so could
cause an ACC system failure or malfunction.
When the condition that deactivated the system is no
longer present, the system will return to the “Adaptive
Cruise Control Off” state and will resume function by
simply reactivating it.
NOTE:
 If the “ACC/FCW Unavailable Wipe Front Radar Sensor”
message occurs frequently (e.g. more than once on
every trip) without any snow, rain, mud, or other
obstruction, have the radar sensor realigned at an
authorized dealer.
 Installing a snowplow, front-end protector, an after -
market grille or modifying the grille is not recom -
mended. Doing so may block the sensor and inhibit
ACC/FCW operation.
“CLEAN FRONT WINDSHIELD” WARNING
The “ACC/FCW Limited Functionality Clean Front
Windshield” warning will display and a chime will sound
when conditions temporarily limit system performance.
This most often occurs at times of poor visibility, such as
in snow or heavy rain and fog.
The ACC system may also become temporarily blinded due
to obstructions, such as mud, dirt, or ice on windshield,
driving directly into the sun and fog on the inside of glass.
In these cases, the instrument cluster display will show
“ACC/FCW Limited Functionality Clean Front Windshield”
and the system will have degraded performance.
This message can sometimes be displayed while driving in
adverse weather conditions. The ACC/FCW system will
recover after the vehicle has left these areas. Under rare
conditions, when the camera is not tracking any vehicles
or objects in its path this warning may temporarily occur.
If weather conditions are not a factor, the driver should
examine the windshield and the camera located on the
back side of the inside rearview mirror. They may require
cleaning or removal of an obstruction.
When the condition that created limited functionality is no
longer present, the system will return to full functionality.
NOTE:If the “ACC/FCW Limited Functionality Clean Front Wind -
shield” message occurs frequently (e.g. more than once
on every trip) without any snow, rain, mud, or other
obstruction, have the windshield and forward facing
camera inspected at an authorized dealer.

STARTING AND OPERATING179
(Continued)
Some trailers (such as boat trailers) will need to
recalibrate while loaded and unloaded.
NOTE:

The system may not detect a trailer in low light condi -
tions. In sunny conditions, the performance may be
degraded as shadows pass over the trailer.
 The driver is always responsible for safe operation of
truck and trailer.
 The driver is always in control of the truck as well as the
trailer and is responsible for controlling the throttle and
brakes.
 The system may not function when the camera lens is
blocked, blurred (covered with water, snow, ice, dirt,
etc) and will not work unless the tailgate is upright and
fully latched.
TOWING REQUIREMENTS
To promote proper break-in of your new vehicle drivetrain
components, the following guidelines are recommended. Perform the maintenance listed in the Scheduled
Servicing section for the proper maintenance intervals
Úpage 333. When towing a trailer, never exceed the
GAWR or GCWR ratings.
Towing Requirements — Tires
 Do not attempt to tow a trailer while using a compact
spare tire.
 Do not drive more than 50 mph (80 km/h) when towing
while using a full size spare tire.
 Proper tire inflation pressures are essential to the safe
and satisfactory operation of your vehicle.
 Check the trailer tires for proper tire inflation pressures
before trailer usage.
 Check for signs of tire wear or visible tire damage
before towing a trailer.
 Replacing tires with a higher load carrying capacity will
not increase the vehicle's GVWR and GAWR limits.
 For further information
Úpage 370.
CAUTION!
Do not tow a trailer at all during the first 500 miles
(805 km) the new vehicle is driven. The engine, axle
or other parts could be damaged.
 Then, during the first 500 miles (805 km) that a
trailer is towed, do not drive over 50 mph (80 km/h)
and do not make starts at full throttle. This helps the
engine and other parts of the vehicle wear in at the
heavier loads.
WARNING!
Make certain that the load is secured in the trailer
and will not shift during travel. When trailering cargo
that is not fully secured, dynamic load shifts can
occur that may be difficult for the driver to control.
You could lose control of your vehicle and have a
collision.
 When hauling cargo or towing a trailer, do not over -
load your vehicle or trailer. Overloading can cause a
loss of control, poor performance or damage to
brakes, axle, engine, transmission, steering, suspen -
sion, chassis structure or tires.
 Safety chains must always be used between your
vehicle and trailer. Always connect the chains to the
hook retainers of the vehicle hitch. Cross the chains
under the trailer tongue and allow enough slack for
turning corners.
 Vehicles with trailers should not be parked on a
grade. When parking, apply the parking brake on the
tow vehicle. Put the tow vehicle transmission in
PARK. For four-wheel drive vehicles, make sure the
transfer case is not in NEUTRAL. Always, block or
"chock" the trailer wheels.
 GCWR must not be exceeded.
Total weight must be distributed between the tow
vehicle and the trailer such that the following four
ratings are not exceeded :
 GVWR
 GTW
 GAWR
 Tongue weight rating for the trailer hitch utilized
WARNING!

STARTING AND OPERATING185
BEFORE PLOWING
Check the hydraulic system for leaks and proper fluid
level.
 Check the mounting bolts and nuts for proper tight -
ness.
 Check the runners and cutting edge for excessive wear.
The cutting edge should be ¼ to ½ inches
(6 cm to 1.2 cm) above ground in snow plowing
position.
 Check that snowplow lighting is connected and
functioning properly.
SNOWPLOW PREP PACKAGE MODEL
A
VAILABILITY
For Information about snowplow applications visit
www.ramtrucks.com or refer to the current Body Builder’s
Guide.

1. The maximum number of occupants in the truck
should not exceed one.

2. The total GVWR, Front GAWR or the Rear GAWR should never be exceeded.
3. Cargo capacity will be reduced by the addition of options or passengers, etc.
The loaded vehicle weight, including the snowplow
system, all aftermarket accessories, driver, passengers,
options, and cargo, must not exceed either the Gross
Vehicle Weight (GVWR) or Gross Axle Weight (GAWR)
ratings. These weights are specified on the Safety Compliance Certification Label on the driver's side door
opening.
NOTE:Detach the snowplow when transporting passengers.
Vehicle front end wheel alignment was set to
specifications at the factory without consideration for the
weight of the plow. Front end toe-in should be checked
and reset if necessary at the beginning and end of the
snowplow season. This will help prevent uneven tire wear.
The blade should be lowered whenever the vehicle is
parked.
Maintain and operate your vehicle and snowplow
equipment following the recommendations provided by
the specific snowplow manufacturer.
OVER THE ROAD OPERATION WITH
S
NOWPLOW ATTACHED
The blade restricts air flow to the radiator and causes the
engine to operate at higher than normal temperatures.
Therefore, when transporting the plow, angle the blade
completely and position it as low as road or surface
conditions permit. Do not exceed 40 mph (64 km/h). The
operator should always maintain a safe stopping distance
and allow adequate passing clearance.
NOTE:Lane Departure Warning / Lane Keep Assist is not
available when a snow plow is attached.
OPERATING TIPS
Under ideal snow plowing conditions, 20 mph (32 km/h)
should be maximum operating speed. The operator should
be familiar with the area and surface to be cleaned.
Reduce speed and use extreme caution when plowing
unfamiliar areas or under poor visibility.
GENERAL MAINTENANCE
Snowplows should be maintained in accordance with the
plow manufacturer's instructions.
Keep all snowplow electrical connections and battery
terminals clean and free of corrosion.
When plowing snow, to avoid transmission and drivetrain
damage, the following precautions should be observed:
 Operate with transfer case in 4WD LOW when plowing
small or congested areas where speeds are not likely to
exceed 15 mph (24 km/h). At higher speeds operate in
4WD HIGH.
 Vehicles with automatic transmissions should use
4WD LOW when plowing deep or heavy snow for
extended periods of time to avoid transmission over -
heating.
 Do not shift the transmission unless the engine has
returned to idle and wheels have stopped. Make a
practice of stepping on the brake pedal while shifting
the transmission.
