2014 Ram 3500 four wheel drive

If the light remains lit with the engine running, your
vehicle will usually be drivable. However, see an autho-
rized dealer for service as soon as possible. If the light is
flashing when the engine is running, immediate service is
required. You may experience reduced performance, an
elevated/rough idle or engine stall and your vehicle may
require towing.

rotate at the same speed. Low range provides a greater
gear reduction ratio to provide increased torque at the
wheels.

and proper use, refer to “Four-Wheel Drive Operation —
If Equipped” in “Starting And Operating”.
32. 4WD AUTO Indicator Light — If EquippedThis light alerts the driver that the vehicle is in
the four-wheel drive auto mode, and the front
axle is engaged, but the vehicle’s power is sent
to the rear wheels. Four-wheel drive will be
automatically engaged when the vehicle senses a loss of
traction.
For further information on four-wheel drive operation
and proper use, refer to “Four-Wheel Drive Operation —
If Equipped” in “Starting And Operating”. 33. 4WD Indicator Light — If Equipped
This light alerts the driver that the vehicle is in
the four-wheel drive mode, and the front and
rear driveshafts are mechanically locked to-

•Electronic Speed Control Ready
This light will turn on when the electronic
speed control is ON. For further information,
refer to “Electronic Speed Control” in “Under-
standing The Features Of Your Vehicle.”
• Hill Decent Control (HDC) — If Equipped
The symbol indicates the status of the Hill
Decent Control (HDC) feature. The lamp will
be on solid when HDC is armed. HDC can only
be armed when the transfer case is in the “4WD
Low” position and the vehicle speed is less then 30 mph (48 km/h). If these conditions are not met while attempt-
ing to use the HDC feature, the HDC indicator lamp will
flash on/off.
Four-Wheel Drive Models With MP3023 Two-Speed
Transfer Case OnlyHDC maintains vehicle speed while
descending hills during off-road driving situations and is
available in 4WD LOW range only. To enable HDC, press
the HDC switch When HDC is enabled, the HDC icon
will be illuminated in the instrument cluster. HDC will
automatically apply the brakes to control downhill speed
to the selected level when necessary on grades greater
than approximately 8%. It will usually not activate on
level ground.

NOTE:On four-wheel drive vehicles be sure that the
transfer case is in a drive position.
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 move-
ment and possible injury or damage.
• Your vehicle could move and injure you and others
if it is not in PARK. Make sure the transmission is
in PARK before leaving the vehicle.
(Continued)
WARNING! (Continued)
•It is dangerous to shift out of PARK or NEUTRAL
if the engine speed is higher than idle speed. If
your foot is not firmly pressing the brake pedal, the
vehicle could accelerate quickly forward or in re-
verse. You could lose control of the vehicle and hit
someone or something. Only shift into gear when
the engine is idling normally and your foot is
firmly pressing the brake pedal.

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.
NOTE: To select the proper gear position for maximum
deceleration (engine braking), simply press and hold the
shift lever to the left (-) (console shift) or the ERS (-)
switch down (column shift). The transmission will shift
to the range from which the vehicle can best be slowed
down.
CAUTION!
When using ERS for engine braking while descend-
ing steep grades, be careful not to overspeed the
engine. Apply the brakes as needed to prevent en-
gine overspeed.
Overdrive Operation
The automatic transmission includes an electronically
controlled Overdrive (fourth and fifth gears). The trans-
mission will automatically shift into Overdrive if the
following conditions are present:
• the shift lever is in the DRIVE position,
• the transmission fluid has reached an adequate tem-
perature,
• the engine coolant (antifreeze) has reached an ad-
equate temperature,
• vehicle speed is sufficiently high, and

PARK (P)
This range supplements the parking brake by locking the
transmission. The engine can be started in this range.
Never attempt to use PARK while the vehicle is in
motion. Apply the parking brake when leaving the
vehicle in this range.
When parking on a level surface, you may shift the
transmission into PARK first, and then apply the parking
brake.
When parking on a hill, apply the parking brake before
shifting the transmission to PARK, otherwise the load on
the transmission locking mechanism may make it diffi-
cult to move the shift lever out of PARK. As an added
precaution, turn the front wheels toward the curb on a
downhill grade and away from the curb on an uphill
grade.On four-wheel drive vehicles be sure that the transfer
case is in a drive position.
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 move-
ment and possible injury or damage.
• Your vehicle could move and injure you and others
if it is not completely in PARK. Check by trying to
move the shift lever out of PARK with the brake
pedal released. Make sure the transmission is in
PARK before leaving the vehicle.
