134STARTING AND OPERATING
engine shutdown, perform this procedure only in a
desired location (preferably, at an authorized
dealer).

1. Stop the vehicle.

2. Shift the transmission into PARK, if possible. If not, shift the transmission to NEUTRAL.
3. Push and hold the ignition switch until the engine turns off.
4. Wait approximately 30 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is no longer detected, the
transmission will return to normal operation.
NOTE:Even if the transmission can be reset, we
recommend that you visit an authorized dealer at
your earliest possible convenience. An authorized
dealer has diagnostic equipment to assess the
condition of your transmission.
If the transmission cannot be reset, authorized
dealer service is required.
Electronic Range Select (ERS) Operation
The ERS shift control allows the driver to limit the
highest available gear when the transmission is in
DRIVE. For example, if you set the transmission
gear limit to FOURTH gear, the transmission will not shift above FOURTH gear (except to prevent
engine overspeed), but will shift through the lower
gears normally.
You can switch between DRIVE and ERS mode at
any vehicle speed. When the transmission gear
selector is in DRIVE, the transmission will operate
automatically, shifting between all available gears.
Tapping the GEAR “–” switch (on the steering
wheel) will activate ERS mode, display the current
gear in the instrument cluster, and set that gear as
the top available gear. Once in ERS mode, tapping
the GEAR “–” or GEAR “+” switch will change the
top available gear.

ERS Control
To exit ERS mode, simply push and hold the
GEAR “+” switch until the gear limit display
disappears from the instrument cluster.
When to Use TOW/HAUL Mode
When driving in hilly areas, towing a trailer, carrying
a heavy load, etc., and frequent transmission
shifting occurs, push the TOW/HAUL switch to
activate TOW/HAUL mode. This will improve
performance and reduce the potential for
transmission overheating or failure due to
excessive shifting.

TOW/HAUL Switch

1 — GEAR “+” Switch
2 — GEAR “–” Switch
WARNING!
Do not downshift for additional engine braking
on a slippery surface. The drive wheels could
lose their grip and the vehicle could skid,
causing a collision or personal injury.

23_DPF_OM_EN_USC_t.book Page 134

STARTING AND OPERATING137
If the transmission temperature exceeds normal
operating limits, the powertrain controller will
modify the transmission shift schedule and expand
the range of torque converter clutch engagement.
This is done to prevent transmission damage due
to overheating.
If the transmission becomes extremely hot or is in
danger of overheating, the Transmission
Temperature Warning Light may illuminate and the
transmission may operate differently until the
transmission cools down.
NOTE:Use caution when operating a heavily loaded
vehicle at low speeds (such as towing a trailer up a
steep grade, or in stop-and-go traffic) during hot
weather. In these conditions, torque converter slip
can impose a significant additional heat load on
the cooling system. Downshifting the transmission
to the lowest possible gear (when climbing a
grade), or shifting to NEUTRAL (when stopped in
heavy traffic) can help to reduce this excess heat
generation.
During cold temperatures, transmission operation
may be modified depending on engine and
transmission temperature as well as vehicle
speed. This feature improves warm-up time of the
engine and transmission to achieve maximum
efficiency. Engagement of the torque converter
clutch is inhibited until the transmission fluid is
warm Ú page 139. On trucks with AS66RC or AS69RC transmission,
FIFTH and SIXTH gears may be inhibited briefly on
cold starts below 41°F (5°C), and during very cold
temperatures (-4°F [-20°C] or below), operation
may briefly be limited to third gear only. During this
condition, the ability of the vehicle to accelerate
under heavily loaded conditions may be reduced.
In all cases, normal operation will resume once the
transmission temperature has risen to a suitable
level.
Transmission Limp Home Mode
Transmission function is monitored electronically
for abnormal conditions. If a condition is detected
that could result in transmission damage,
Transmission Limp Home Mode is activated. In this
mode, the transmission remains in THIRD gear
regardless of which forward gear is selected. If an
AS66RC/AS69RC equipped truck enters
Transmission Limp Home Mode at highway
speeds, it will initially engage FIFTH gear, until the
vehicle slows to a speed where THIRD gear can be
engaged. PARK, REVERSE, and NEUTRAL will
continue to operate. The Malfunction Indicator
Light (MIL) may be illuminated. Transmission Limp
Home Mode allows the vehicle to be driven to an
authorized dealer for service without damaging the
transmission.
In the event of a momentary problem, the
transmission can be reset to regain all forward
gears by performing the following steps:

1. Stop the vehicle.

2. Shift the transmission into PARK.
3. Turn the ignition to the OFF position.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the
problem is no longer detected, the
transmission will return to normal operation.
NOTE:Even if the transmission can be reset, we
recommend that you visit an authorized dealer at
your earliest possible convenience. An authorized
dealer has diagnostic equipment to assess the
condition of your transmission.
If the transmission cannot be reset, authorized
dealer service is required.
Electronic Range Select (ERS) Operation
The ERS shift control allows the driver to limit the
highest available gear when the transmission is in
DRIVE. For example, if you set the transmission
gear limit to FOURTH gear, the transmission will
not shift above FOURTH gear, but will shift through
the lower gears normally.

138STARTING AND OPERATING
You can switch between DRIVE and ERS mode at
any vehicle speed. When the gear selector is in the
DRIVE position, the transmission will operate
automatically, shifting between all available gears.
Tapping the ERS “-” switch will activate ERS mode,
display the current gear in the instrument cluster,
and set that gear as the top available gear. Once in
ERS mode, tapping “-” or “+” will change the top
available gear.

Electronic Range Select

To exit ERS mode, simply push and hold the
ERS “+” switch until the gear limit display
disappears from the instrument cluster.
NOTE:To select the proper gear position for maximum
deceleration (engine braking), simply push and
hold the ERS “-” switch. The transmission will shift
to the range from which the vehicle can best be
slowed down.
Overdrive Operation

The automatic transmission includes an
electronically controlled Overdrive (FIFTH and SIXTH
gears). The transmission will automatically shift into
Overdrive if the following conditions are present:

The gear selector is in the DRIVE position.
The transmission fluid has reached an
adequate temperature.
The engine coolant has reached an adequate
temperature.
Vehicle speed is sufficiently high.
The TOW/HAUL switch has not been activated.
The driver is not heavily pressing the acceler -
ator.
When To Use TOW/HAUL Mode
When driving in hilly areas, towing a trailer, carrying
a heavy load, etc., and frequent transmission
shifting occurs, push the TOW/HAUL switch to
activate TOW/HAUL mode. This will improve
performance and reduce the potential for
transmission overheating or failure due to
excessive shifting. When operating in TOW/HAUL
mode, transmission upshifts are delayed, and the
transmission will automatically downshift (for
engine braking) when the throttle is closed and/or
during steady braking maneuvers.

TOW/HAUL Switch

1 — GEAR “+” Switch
2 — GEAR “–” Switch
WARNING!
Do not downshift for additional engine braking
on a slippery surface. The drive wheels could
lose their grip and the vehicle could skid,
causing a collision or personal injury.
CAUTION!
When using ERS for engine braking while
descending steep grades, be careful not to
overspeed the engine. Apply the brakes as
needed to prevent engine overspeed.

180STARTING AND OPERATING
(Continued)
Refilling With Containers
Proceed as follows:
Check the expiration date.

Read the advice for use on the label before
pouring the content of the bottle into the DEF tank.

After the indication appears on the instrument
cluster display
Úpage 89 fill the DEF tank with
no more than 6 gal (22 L).
Stop filling the DEF tank immediately if DEF
splashes or wells back in the filler neck.
Reinstall cap onto DEF filler tube.
Filling The Def Tank In Cold Climates
Since DEF will begin to freeze at 12°F (-11°C),
your vehicle is equipped with an automatic DEF
heating system. This allows the DEF injection
system to operate properly at temperatures below
12°F (-11°C). If your vehicle is not in operation for
an extended period of time with temperatures
below 12°F (-11°C), the DEF in the tank may
freeze. If the tank is overfilled and freezes, it could
be damaged. Therefore, do not overfill the DEF
tank. Extra care should be taken when filling with
portable containers to avoid overfilling. Note the
level of the DEF gauge in your instrument cluster.
You may safely add a maximum of 2 gal (7.5 L) of
DEF from portable containers when your DEF
gauge is reading ½ full.VEHICLE LOADING
GROSS VEHICLE WEIGHT RATING
(GVWR)
The GVWR is the total permissible weight of your
vehicle including driver, passengers, vehicle,
options and cargo. The label also specifies
maximum capacities of front and rear axle systems
(GAWR). Total load must be limited so GVWR and
front and rear GAWR are not exceeded.
PAYLOAD
The payload of a vehicle is defined as the allowable
load weight a truck can carry, including the weight
of the driver, all passengers, options and cargo.
GROSS AXLE WEIGHT RATING (GAWR)
The GAWR is the maximum permissible load on the
front and rear axles. The load must be distributed
in the cargo area so that the GAWR of each axle is
not exceeded.
CAUTION!
To avoid DEF spillage, and possible damage to
the DEF tank from overfilling, do not “top off”
the DEF tank after filling.
DO NOT OVERFILL. DEF will freeze below 12ºF
(-11ºC). The DEF system is designed to work in
temperatures below the DEF freezing point,
however, if the tank is overfilled and freezes,
the system could be damaged.
When DEF is spilled, clean the area immedi -
ately with water and use an absorbent mate -
rial to soak up the spills on the ground.
Do not attempt to start your engine if DEF is
accidentally added to the diesel fuel tank as it
can result in severe damage to your engine,
including but not limited to failure of the fuel
pump and injectors.

Never add anything other than DEF to the
tank – especially any form of hydrocarbon
such as diesel fuel, fuel system additives,
gasoline, or any other petroleum-based
product. Even a very small amount of these,
less than 100 parts per million or less than
1 oz. per 78 gal (295 L) will contaminate the
entire DEF system and will require replace -
ment. If owners use a container, funnel or
nozzle when refilling the tank, it should either
be new or one that has only been used for
adding DEF. Mopar® provides an attachable
nozzle with its DEF for this purpose.

CAUTION!

192STARTING AND OPERATING
TOWING TIPS
Before setting out on a trip, practice turning,
stopping, and backing up the trailer in an area
located away from heavy traffic.
Automatic Transmission

The DRIVE range can be selected when towing. The
transmission controls include a drive strategy to
avoid frequent shifting when towing. However, if
frequent shifting does occur while in DRIVE, select
TOW/HAUL mode or select a lower gear range (using
the Electronic Range Select (ERS) shift control).

NOTE:Using TOW/HAUL mode or selecting a lower gear
range (using the ERS shift control) while operating
the vehicle under heavy loading conditions will
improve performance and extend transmission life
by reducing excessive shifting and heat build-up.
This action will also provide better engine braking.
6-Speed Automatic Transmission Only
When towing a loaded trailer up steep grades at
low speeds (20 mph [32 km/h] or below), holding
your vehicle in FIRST gear (using the ERS shift
control) can help to avoid transmission
overheating.

If you regularly tow a trailer for more than 45 minutes
of continuous operation, then change the automatic
transmission fluid and filter(s) as specified for "police,
taxi, fleet, or frequent trailer towing."
Ú
page 344.

NOTE:Check the automatic transmission fluid level
before towing (6-speed automatic only).
Tow/Haul Mode
To reduce potential for automatic transmission
overheating, activate TOW/HAUL mode when
driving in hilly areas, or select a lower gear range
(using the Electronic Range Select (ERS) shift
control) on more severe grades.
Cruise Control — If Equipped
Do not use on hilly terrain or with heavy loads.
When using the Cruise Control, if you experience
speed drops greater than 10 mph (16 km/h),
disengage until you can get back to cruising
speed.
Use Cruise Control in flat terrain and with light
loads to maximize fuel efficiency.
SNOWPLOW — IF EQUIPPED
Snowplow Prep Packages are available as a factory
installed option. These packages include
components necessary to equip your vehicle with a
snowplow.
NOTE:Before installation of a snowplow it is highly recom -
mended that the owner/installer obtain and follow
the recommendations contained within the current
Body Builder’s Guide. See an authorized dealer, installer or snowplow manufacturer for this infor
-
mation. There are unique electrical systems that
must be connected to properly ensure operator
safety and prevent overloading vehicle systems.
BEFORE PLOWING
Check the hydraulic system for leaks and proper
fluid level.
Check the mounting bolts and nuts for proper
tightness.
Check the runners and cutting edge for exces -
sive 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.
WARNING!
Attaching a snowplow to this vehicle could
adversely affect performance of the airbag
system in a collision. Do not expect that the
airbag will perform as described earlier in this
manual.
CAUTION!
The “Lamp Out” indicator could illuminate if
exterior lamps are not properly installed.

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 two.

2. The total GVWR or the 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 Rating (GVWR) or
Gross Axle Weight Rating (GAWR). 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.
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 overheating.
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.

(Continued)
Lights
Have someone observe the operation of brake
lights and exterior lights while you work the
controls. Check turn signal and high beam
indicator lights on the instrument panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under the vehicle after overnight
parking for fuel, coolant, oil, or other fluid leaks.
Also, if gasoline fumes are detected or if fuel or
brake fluid leaks are suspected, the cause should
be located and corrected immediately.
EXHAUST GAS
The best protection against carbon monoxide entry
into the vehicle body is a properly maintained
engine exhaust system.
Whenever a change is noticed in the sound of the
exhaust system, when exhaust fumes can be
detected inside the vehicle, or when the underside
or rear of the vehicle is damaged, have an
authorized dealer inspect the complete exhaust
system and adjacent body areas for broken,
damaged, deteriorated, or mispositioned parts.
Open seams or loose connections could permit
exhaust fumes to seep into the passenger
compartment. In addition, inspect the exhaust
system each time the vehicle is raised for
lubrication or oil change. Replace as required.
CARBON MONOXIDE WARNINGS
WARNING!
Exhaust gases can injure or kill. They contain
carbon monoxide (CO), which is colorless and
odorless. Breathing it can make you
unconscious and can eventually poison you. To
avoid breathing (CO), follow these safety tips:
Do not run the engine in a closed garage or in
confined areas any longer than needed to
move your vehicle in or out of the area.
If you are required to drive with the trunk/lift -
gate/rear doors open, make sure that all
windows are closed and the climate control
BLOWER switch is set at high speed. DO NOT
use the recirculation mode.
If it is necessary to sit in a parked vehicle with
the engine running, adjust your heating or
cooling controls to force outside air into the
vehicle. Set the blower at high speed.
WARNING!
WARNING!
Carbon monoxide (CO) in exhaust gases is
deadly. Follow the precautions below to prevent
carbon monoxide poisoning:
Do not inhale exhaust gases. They contain
carbon monoxide, a colorless and odorless
gas, which can kill. Never run the engine in a
closed area, such as a garage, and never sit in
a parked vehicle with the engine running for
an extended period. If the vehicle is stopped in
an open area with the engine running for more
than a short period, adjust the ventilation
system to force fresh, outside air into the
vehicle.
Guard against carbon monoxide with proper
maintenance. Have the exhaust system
inspected every time the vehicle is raised.
Have any abnormal conditions repaired
promptly. Until repaired, drive with all side
windows fully open.

23_DPF_OM_EN_USC_t.book Page 324

IN CASE OF EMERGENCY335
5. Start the engine in the vehicle that has the booster battery, let the engine idle a few
minutes, and then start the engine in the
vehicle with the discharged battery.
6. Once the engine is started, follow the discon -
necting procedure.
Disconnecting The Jumper Cables

1. Disconnect the negative
(-)
end of the jumper
cable from the engine ground of the vehicle
with the discharged battery.

2. Disconnect the opposite end of the negative (-)
jumper cable from the negative (-) post of the
booster battery.
3. Disconnect the positive (+) end of the jumper
cable from the positive (+) post of the booster
battery.
4. Disconnect the opposite end of the positive (+)
jumper cable from the positive (+) post of the
vehicle with the discharged battery, and
reinstall the protective cap over the positive
(+) post. If frequent jump starting is required to start your
vehicle you should have the battery and charging
system inspected at an authorized dealer.
IF YOUR ENGINE OVERHEATS
If the vehicle is overheating, it will need to be
serviced by an authorized dealer.
Potential signs of vehicle overheating:
Temperature gauge is at HOT (H)
Strong smell of coolant
White smoke coming from engine or exhaust
Coolant bottle coolant has bubbles present
In the event it is observed that the temperature
gauge is moving towards or close to the HOT (H)
position, you can reduce the potential for
overheating by taking the appropriate action.
On the highways — slow down.
In city traffic — while stopped, place the trans
-
mission in NEUTRAL (N), but do not increase the
engine idle speed while preventing vehicle
motion with the brakes.
If your Air Conditioner (A/C) is on, turn it off. The
A/C system adds heat to the engine cooling
system and turning the A/C off can help remove
this heat.
You can also turn the temperature control to
maximum heat, the mode control to floor and
the blower control to high. This allows the heater
core to act as a supplement to the radiator and
aids in removing heat from the engine cooling
system.
CAUTION!
Do not connect jumper cable to any of the fuses
on the positive battery terminal. The resulting
electrical current will blow the fuse.
CAUTION!
Accessories plugged into the vehicle power
outlets draw power from the vehicle’s battery,
even when not in use (i.e., cellular devices, etc.).
Eventually, if plugged in long enough without
engine operation, the vehicle’s battery will
discharge sufficiently to degrade battery life
and/or prevent the engine from starting.
WARNING!
You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator.
If you see or hear steam coming from under the
hood, do not open the hood until the radiator
has had time to cool. Never try to open a cooling
system pressure cap when the radiator or
coolant bottle is hot.

3. Pull gently on the tether strap to confirm that the lever is locked in its stowed position.

Manual Park Release Tether In Stowed Position

4. Reinstall the access cover.
FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand, or
snow, it can often be moved using a rocking
motion. Turn the steering wheel right and left to
clear the area around the front wheels. Then shift
back and forth between DRIVE (D) and REVERSE
(R), while gently pressing the accelerator. Use the least amount of accelerator pedal pressure that
will maintain the rocking motion, without spinning
the wheels or racing the engine.
NOTE:
For trucks equipped with an 8–speed transmis
-
sion, shifts between DRIVE and REVERSE can
only be achieved at wheel speeds of 5 mph
(8 km/h) or less. Whenever the transmission
remains in NEUTRAL (N) for more than two
seconds, you must press the brake pedal to
engage DRIVE or REVERSE.
Push the ESC OFF button, to place the Electronic
Stability Control (ESC) system in “Partial Off”
mode, before rocking the vehicle Ú page 271.
Once the vehicle has been freed, push the ESC
OFF button again to restore ESC On mode.
WARNING!
Fast spinning tires can be dangerous. Forces
generated by excessive wheel speeds may
cause damage, or even failure, of the axle and
tires. A tire could explode and injure someone.
Do not spin your vehicle's wheels faster than
30 mph (48 km/h) or for longer than 30
seconds continuously without stopping when
you are stuck and do not let anyone near a
spinning wheel, no matter what the speed.
CAUTION!
Racing the engine or spinning the wheels may
lead to transmission overheating and failure.
Allow the engine to idle with the transmission
in NEUTRAL for at least one minute after every
five rocking-motion cycles. This will minimize
overheating and reduce the risk of transmis -
sion failure during prolonged efforts to free a
stuck vehicle.
When “rocking” a stuck vehicle by shifting
between DRIVE and REVERSE, do not spin the
wheels faster than 15 mph (24 km/h), or
drivetrain damage may result.
Revving the engine or spinning the wheels too
fast may lead to transmission overheating and
failure. It can also damage the tires. Do not
spin the wheels above 30 mph (48 km/h)
while in gear (no transmission shifting occur -
ring).

4. Slide the wiper blade up into the hook on the
wiper arm until it is latched (engagement will
be accompanied by an audible click). Fold
down the latch release tab and snap it into its
locked position.
5. Gently lower the wiper blade onto the glass.
EXHAUST SYSTEM
The best protection against carbon monoxide entry
into the vehicle body is a properly maintained
engine exhaust system.
If you notice a change in the sound of the exhaust
system; or if the exhaust fumes can be detected
inside the vehicle; or when the underside or rear of
the vehicle is damaged; have an authorized
technician inspect the complete exhaust system
and adjacent body areas for broken, damaged,
deteriorated, or mispositioned parts. Open seams
or loose connections could permit exhaust fumes
to seep into the passenger compartment. In
addition, have the exhaust system inspected each
time the vehicle is raised for lubrication or oil
change. Replace as required. Under normal operating conditions, the catalytic
converter will not require maintenance. However, it
is important to keep the engine properly tuned to
ensure proper catalyst operation and prevent
possible catalyst damage.
NOTE:Intentional tampering with emissions control
systems can result in civil penalties being
assessed against you.
In unusual situations involving grossly
malfunctioning engine operation, a scorching odor
may suggest severe and abnormal catalyst
overheating. If this occurs, stop the vehicle, turn off
the engine and allow it to cool. Service, including a
tune-up to manufacturer's specifications, should
be obtained immediately.
WARNING!
Exhaust gases can injure or kill. They contain
carbon monoxide (CO), which is colorless and
odorless. Breathing it can make you uncon
-
scious and can eventually poison you
Ú page 324.
A hot exhaust system can start a fire if you
park over materials that can burn. Such mate -
rials might be grass or leaves coming into
contact with your exhaust system. Do not park
or operate your vehicle in areas where your
exhaust system can contact anything that can
burn.
CAUTION!
The catalytic converter requires the use of
unleaded fuel only. Leaded gasoline will
destroy the effectiveness of the catalyst as an
emissions control device and may seriously
reduce engine performance and cause
serious damage to the engine.
Damage to the catalytic converter can result if
your vehicle is not kept in proper operating
condition. In the event of engine malfunction,
particularly involving engine misfire or other
apparent loss of performance, have your
vehicle serviced promptly. Continued opera -
tion of your vehicle with a severe malfunction
could cause the converter to overheat,
resulting in possible damage to the converter
and vehicle.
CAUTION!
