AIR DAM RAM 1500 2021 User Guide

STARTING AND OPERATING153
If exceptional circumstances should make it
necessary to engage the parking brake while
the vehicle is in motion, maintain upward
pressure on the EPB switch for as long as
engagement is desired. The BRAKE telltale light
will illuminate, and a continuous chime will
sound. The rear stop lamps will also be
illuminated automatically while the vehicle
remains in motion.
To disengage the parking brake while the
vehicle is in motion, release the switch. If the
vehicle is brought to a complete stop using the
parking brake, when the vehicle reaches
approximately 3 mph, (5 km/h) the parking
brake will remain engaged. In the unlikely event of a malfunction of the EPB
system, a yellow EPB fault light will illuminate.
This may be accompanied by the BRAKE telltale
light flashing. In this event, urgent service of the
EPB system is required. Do not rely on the
parking brake to hold the vehicle stationary.
Auto Park Brake
The Electric Park Brake (EPB) can be
programmed to be applied automatically
whenever the vehicle is at a standstill and the
automatic transmission is placed in PARK. Auto
Park Brake is enabled and disabled by
customer selection through the customer
programmable features section of the Uconnect
Settings Ú
page 245.
Any single Auto Park Brake application can be
bypassed by pushing the EPB switch to the
release position while the transmission is
placed in PARK.
SafeHold
SafeHold is a safety feature of the Electric Park
Brake (EPB) system that will engage the parking
brake automatically if the vehicle is left
unsecured while the ignition is in ON/RUN. The parking brake will automatically engage if
all of the following conditions are met:
The vehicle is at a standstill.
There is no attempt to press the brake pedal
and accelerator pedal.
The seat belt is unbuckled.
The driver door is open.
SafeHold can be temporarily bypassed by
pushing the EPB switch while the driver door is
open. Once manually bypassed, SafeHold will
be enabled again once the vehicle reaches
12 mph (20 km/h) or the ignition is turned to
the OFF position and back to ON again.
Brake Service Mode
We recommend having your brakes serviced by
an authorized dealer. You should only make
repairs for which you have the knowledge and
the right equipment. You should only enter
Brake Service Mode during brake service.
When servicing your rear brakes, it may be
necessary for you or your technician to push the
rear piston into the rear caliper bore. With the
Electric Park Brake (EPB) system, this can only
be done after retracting the EPB actuator.
WARNING!
Driving the vehicle with the parking brake
engaged, or repeated use of the parking
brake to slow the vehicle may cause serious
damage to the brake system. Be sure the
parking brake is fully disengaged before
driving; failure to do so can lead to brake
failure and a collision.

STARTING AND OPERATING165
NOTE:
Do not attempt to make a shift while only the
front or rear wheels are spinning. This could
cause damage to driveline components.
When operating your vehicle in 4WD Low, the
engine speed is approximately three times that
of the 2WD, 4WD Auto or 4WD High positions
at a given road speed. Take care not to
overspeed the engine and do not exceed
25 mph (40 km/h).
Proper operation of four-wheel drive vehicles
depends on tires of equal size, type and
circumference on each wheel. Any difference in
tire size can cause damage to the drivetrain.
Because four-wheel drive provides improved
traction, there is a tendency to exceed safe
turning and stopping speeds. Do not go faster
than road conditions permit.
Shifting Procedure
If any of the requirements to select a new
transfer case position have not been met,
then the transfer case will not shift. The posi -
tion indicator light for the previous position
will remain on and the newly selected posi -
tion indicator light will continue to flash until
all the requirements for the selected position
have been met.
If all the requirements to select a new
transfer case position have been met, then
the current position indicator light will turn off
and the selected position indicator light will
flash until the transfer case completes the
shift. When the shift is complete, the position
indicator light for the selected position will
stop flashing and remain on.

of the vehicle.
The capless system is sealed by two flapper
doors.

1. Put the vehicle in PARK and switch the
ignition off.

2. Open the fuel filler door.

Diesel Fuel And Diesel Exhaust Fluid Fill Location

3. Insert the fuel nozzle fully into the filler pipe – the nozzle opens and holds the flapper
door while refueling. 4. Fill the vehicle with fuel – when the fuel
nozzle “clicks” or shuts off, the fuel tank is
full.
5. Remove the fuel nozzle and close the fuel door.
AVOID USING CONTAMINATED FUEL
Fuel that is contaminated by water or dirt can
cause severe damage to the engine fuel
system. Proper maintenance of the engine fuel
filter and fuel tank is essential Ú page 409.
BULK FUEL STORAGE — DIESEL FUEL
If you store quantities of fuel, good
maintenance of the stored fuel is also essential.
Fuel contaminated with water will promote the
growth of “microbes.” These microbes form
“slime” that will clog the fuel filtration system
and lines. Drain condensation from the supply
tank and change the line filter on a regular
basis.
NOTE:
When a diesel engine is allowed to run out of
fuel, air is pulled into the fuel system.
If the vehicle will not start Úpage 414.

2 — Diesel Fuel Fill Location
WARNING!
Never have any smoking materials lit in or
near the vehicle when the fuel door is open
or the tank is being filled.
Never add fuel when the engine is running.
This is in violation of most state and federal
fire regulations and may cause the
“Malfunction Indicator Light” to turn on.
A fire may result if fuel is pumped into a
portable container that is inside of a
vehicle. You could be burned. Always place
fuel containers on the ground while filling.
CAUTION!
To avoid fuel spillage and overfilling, do not
“top off” the fuel tank after filling.
WARNING!
Do not open the high pressure fuel system
with the engine running. Engine operation
causes high fuel pressure. High pressure fuel
spray can cause serious injury or death.

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.
