2019 RAM CHASSIS CAB parking brake

SAFETY 171
When TSC is functioning, the “ESC Activation/Malfunction
Indicator Light” will flash, the engine power may be reduced
and you may feel the brakes being applied to individual
wheels to attempt to stop the trailer from swaying. TSC is
disabled when the ESC system is in the “Partial Off” or “Full
Off” modes.
Hill Descent Control (HDC) — If Equipped
HDC is intended for low speed off road driving while in
4WD Low Range. HDC maintains vehicle speed while
descending hills during various driving situations. HDC
controls vehicle speed by actively controlling the brakes.
HDC Has Three States:
1. Off (feature is not enabled and will not activate).
2. Enabled (feature is enabled and ready but activation
conditions are not met, or driver is actively overriding
with brake or throttle application). 3. Active (feature is enabled and actively controlling vehicle
speed).
Enabling HDC
HDC is enabled by pushing the HDC switch, but the
following conditions must also be met to enable HDC:
• Driveline is in 4WD Low Range.
• Vehicle speed is below 5 mph (8 km/h).
• Parking brake is released.
• Driver door is closed.
Activating HDC
Once HDC is enabled it will activate automatically if driven
down a grade of sufficient magnitude. The set speed for
HDC is selectable by the driver, and can be adjusted by using
the gear shift +/-. The following summarizes the HDC set
speeds:
HDC Target Set Speeds
• P = No set speed. HDC may be enabled but will not acti -
vate.
• R = 0.6 mph (1 km/h)WARNING!
If TSC activates while driving, slow the vehicle down,
stop at the nearest safe location, and adjust the trailer
load to eliminate trailer sway.

SAFETY 173
Disabling HDC
HDC will be deactivated and disabled if any of the following
conditions occur:
• The driver pushes the HDC switch.
• The driveline is shifted out of 4WD Low Range.
• The parking brake is applied.
• Driver door opens.
• The vehicle is driven greater than 20 mph (32 km/h) for
greater than 70 seconds.
• The vehicle is driven greater than 40 mph (64 km/h) (HDC
exits immediately).
• HDC detects excessive brake temperature. Feedback To The Driver
The instrument cluster has an HDC icon and the HDC switch
has an LED icon, which offers feedback to the driver about
the state HDC is in.
• The cluster icon and switch lamp will illuminate and
remain on solid when HDC is enabled or activated. This is
the normal operating condition for HDC.
• The cluster icon and switch lamp will flash for several
seconds then extinguish when the driver pushes the HDC
switch but enable conditions are not met.
• The cluster icon and switch lamp will flash for several
seconds then extinguish when HDC disables due to excess
speed.
• The cluster icon and switch lamp will flash when HDC
deactivates due to overheated brakes. The flashing will
stop and HDC will activate again once the brakes have
cooled sufficiently.
WARNING!
HDC is only intended to assist the driver in controlling
vehicle speed when descending hills. The driver must
remain attentive to the driving conditions and is
responsible for maintaining a safe vehicle speed. 4

SAFETY 243
Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect the tread for cuts and
cracks. Inspect sidewalls for cuts, cracks, and bulges. Check
the wheel bolts for tightness. Check the tires (including
spare) for proper cold inflation pressure.
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.• ALWAYS make sure objects cannot fall or slide into the
driver’s side floor area when the vehicle is moving.
Objects can become trapped under accelerator, brake,
or clutch pedals and could cause a loss of vehicle
control.
• NEVER place any objects under the floor mat (e.g.,
towels, keys, etc.). These objects could change the posi -
tion of the floor mat and may cause interference with
the accelerator, brake, or clutch pedals.
• If the vehicle carpet has been removed and re-installed,
always properly attach carpet to the floor and check the
floor mat fasteners are secure to the vehicle carpet.
Fully depress each pedal to check for interference with
the accelerator, brake, or clutch pedals then re-install
the floor mats.
• It is recommended to only use mild soap and water to
clean your floor mats. After cleaning, always check
your floor mat has been properly installed and is
secured to your vehicle using the floor mat fasteners by
lightly pulling mat. WARNING! (Continued)

(Continued)STARTING AND OPERATINGSTARTING THE ENGINE
Before starting your vehicle, adjust your seat, adjust both
inside and outside mirrors, and fasten your seat belt.
The starter should not be operated for more than 10-second
intervals. Waiting a few seconds between such intervals will
protect the starter from overheating.
WARNING!
• When leaving the vehicle, always make sure the
keyless ignition node is in the "OFF" mode, remove the
key fob from the vehicle and lock the vehicle.
• Never leave children alone in a vehicle, or with access
to an unlocked vehicle. Allowing children to be in a
vehicle unattended is dangerous for a number of
reasons. A child or others could be seriously or fatally
injured. Children should be warned not to touch the
parking brake, brake pedal or the gear selector. • Do not leave the key fob in or near the vehicle, or in a
location accessible to children, and do not leave the
ignition of a vehicle equipped with Keyless
Enter-N-Go in the ACC or ON/RUN mode. A child
could operate power windows, other controls, or move
the vehicle.
• Do not leave children or animals inside parked vehicles
in hot weather. Interior heat build-up may cause
serious injury or death. WARNING! (Continued)

Only
AutoPark is a supplemental feature to assist in placing the
vehicle in PARK should the situations on the following
pages occur. It is a back up system and should not be relied
upon as the primary method by which the driver shifts the
vehicle into PARK.
The conditions under which AutoPark will engage are
outlined on the following pages.
WARNING!
• Driver inattention could lead to failure to place the
vehicle in PARK. ALWAYS DO A VISUAL CHECK
that your vehicle is in PARK by verifying that a solid
(not blinking) “P” is indicated in the Instrument
Cluster Display and near the gear selector. If the "P"
indicator is blinking, your vehicle is not in PARK. As
an added precaution, always apply the parking brake
when exiting the vehicle.
• AutoPark is a supplemental feature. It is not designed
to replace the need to shift your vehicle into PARK. It is
a back up system and should not be relied upon as the
primary method by which the driver shifts the vehicle
into PARK. 5

STARTING AND OPERATING 249
If the driver shifts into PARK while moving, the vehicle
may AutoPark.
AutoPark will engage ONLY when vehicle speed is 1.2 MPH
(1.9 km/h) or less.
The MESSAGE “ Vehicle Speed is Too High to Shift to
P ”will be displayed in the instrument cluster if vehicle speed
is above 1.2 MPH (1.9 km/h).
4WD LOW — If Equipped
AutoPark will be disabled when operating the vehicle in
4WD LOW.
The MESSAGE “ AutoPark Disabled ” will be displayed in
the instrument cluster. Additional customer warnings will be given when all of
these conditions are met:
• Vehicle is not in PARK
• Driver’s Door is ajar
• Vehicle is in 4WD LOW range
The MESSAGE “ AutoPark Not Engaged ” will be displayed
in the instrument cluster. A warning chime will continue
until you shift the vehicle into PARK or the Driver’s Door is
closed.
ALWAYS DO A VISUAL CHECK that your vehicle is in
PARK by looking for the "P" in the Instrument Cluster
Display and near the shifter. As an added precaution, always
apply the parking brake when exiting the vehicle.
If Engine Fails To Start
If the engine fails to start after you have followed the
“Normal Starting” procedure, it may be flooded. Push the
accelerator pedal all the way to the floor and hold it there
while the engine is cranking. This should clear any excess
fuel in case the engine is flooded.
The starter motor will engage automatically, run for 10
seconds, and then disengage. Once this occurs, release theWARNING!
If vehicle speed is above 1.2 MPH (1.9 km/h), the
transmission will default to NEUTRAL until the vehicle
speed drops below 1.2 MPH (1.9 km). A vehicle left in
the NEUTRAL position can roll. As an added precaution,
always apply the parking brake when exiting the
vehicle. 5

252 STARTING AND OPERATING
NOTE:
A new engine may consume some oil during its first few
thousand miles (kilometers) of operation. This should be
considered a normal part of the break-in and not interpreted
as a problem. Please check your oil level with the engine oil
indicator often during the break in period. Add oil as
required.
PARKING BRAKE
Before leaving the vehicle, make sure that the parking brake
is fully applied. Also, be certain to leave the transmission in
PARK.
The foot operated parking brake is located below the lower
left corner of the instrument panel. To apply the park brake,
firmly push the park brake pedal fully. To release the
parking brake, pull the parking brake release handle. Parking Brake Release
When the parking brake is applied with the ignition switch
ON, the “Brake Warning Light” in the instrument cluster
will illuminate.
NOTE:
• When the parking brake is applied and the transmission is
placed in gear, the “Brake Warning Light” will flash. If
vehicle speed is detected, a chime will sound to alert the
driver. Fully release the parking brake before attempting
to move the vehicle.
• This light only shows that the parking brake is applied. It
does not show the degree of brake application.

STARTING AND OPERATING 253
(Continued)When parking on a hill, it is important to turn the front
wheels toward the curb on a downhill grade and away from
the curb on an uphill grade. Apply the parking brake before
placing the gear selector in PARK, otherwise the load on the
transmission locking mechanism may make it difficult to
move the gear selector out of PARK. The parking brake
should always be applied whenever the driver is not in the
vehicle.
WARNING!
• Never use the PARK position as a substitute for the
parking brake. Always apply the parking brake fully
when parked to guard against vehicle movement and
possible injury or damage.
• Never leave children alone in a vehicle, or with access
to an unlocked vehicle. Leaving unattended children in
a vehicle is dangerous for a number of reasons. A child
or others could be seriously or fatally injured.
• Do not leave the key fob in or near the vehicle, or in a
location accessible to children, and do not leave a
vehicle equipped with Keyless Enter-N-Go in the ACC
or ON/RUN mode. A child could operate power
windows, other controls, or move the vehicle. • Be sure the parking brake is fully disengaged before
driving; failure to do so can lead to brake failure and a
collision.
• Always fully apply the parking brake when leaving
your vehicle or it may roll and cause damage or injury.
Also, be certain to leave the transmission in PARK.
Failure to do so may cause the vehicle to roll and cause
damage or injury.
CAUTION!
If the Brake System Warning Light remains on with the
parking brake released, a brake system malfunction is
indicated. Have the brake system serviced by an
authorized dealer immediately. WARNING! (Continued)
