keyless Ram 3500 2015 Workshop Manual

STARTING PROCEDURES
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!
•Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Leaving children 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.

WARNING! (Continued)
•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 con-
trols, or move the vehicle.
Normal Starting
Normal starting of either a warm or cold engine is
obtained without pumping or pressing the accelerator
pedal. Cycle the ignition to the START position and
release when the engine starts. If the engine fails to start
within 10 seconds, cycle the ignition to the OFF position,
wait five seconds, then repeat the “Normal Starting”
procedure.
442 STARTING AND OPERATING

Automatic Transmission
Start the engine with the transmission in PARK position.
Apply the brake before shifting into any driving range.
NOTE:
•This vehicle is equipped with a transmission shift
interlocking system. The brake pedal must be pressed
to shift out of PARK.
• If equipped with an 8 speed transmission starting the
vehicle in NEUTRAL is not possible unless the Manual
Park Release has been activated. For the Manual Park
Release operation refer to Manual Park Release in
“What To Do In Emergencies”.
Tip Start Feature
Do not press the accelerator. Cycle the ignition switch
briefly to the START position and release it. The starter
motor will continue to run but will automatically disen-
gage when the engine is running.

WARNING!(Continued)
•Do not leave the Key Fob in or near the vehicle (or
in a location accessible to children), and do not
leave the ignition (in a vehicle equipped with
Keyless Enter-N-Go) in the ACC or ON/RUN posi-

controls, or move the vehicle.
• 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 ON/RUN mode. A child
could operate power windows, other controls, or
move the vehicle.
Key Ignition Park Interlock
This vehicle is equipped with a Key Ignition Park Inter-
lock which requires the transmission to be in PARK
before the ignition switch can be turned to the LOCK/ OFF (key removal) position. The Key Fob can only be
removed from the ignition when the ignition is in the
LOCK/OFF position, and the transmission is locked in
PARK whenever the ignition switch is in the LOCK/OFF
position.
NOTE:
If a malfunction occurs, the system will trap the
Key Fob in the ignition switch to warn you that this
safety feature is inoperable. The engine can be started
and stopped but the Key Fob cannot be removed until
you obtain service.
Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmission Shift
Interlock System (BTSI) that holds the transmission gear
selector in PARK unless the brakes are applied. To shift
the transmission out of PARK, the ignition switch must
be turned to the ON/RUN position (engine running, for
vehicles with eight-speed transmission) and the brake
pedal must be pressed.

458 STARTING AND OPERATING

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 may
operate only in certain gears, or may not shift at all.
Vehicle performance may be severely degraded and the
engine may stall. In some situations, the transmission
may not re-engage if the engine is turned off and
restarted. The Malfunction Indicator Light (MIL) may be
illuminated. A message in the instrument cluster will
inform the driver of the more serious conditions, and
indicate what actions may be necessary.
In the event of a momentary problem, the transmission
can be reset to regain all forward gears by performing the
following steps:NOTE:
In cases where the instrument cluster message
indicates the transmission may not re-engage after en-
gine shutdown, perform this procedure only in a desired
location (preferably, at your authorized dealer).
1. Stop the vehicle.
2. Shift the transmission into PARK, if possible. If not, shift the transmission to NEUTRAL.
3. Turn the ignition switch to the OFF position. On vehicles with Keyless Enter-N-Go™, 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.

tion:
• When shifting into PARK, pull the column-mounted
shift lever toward you and move it all the way
counterclockwise until it stops. For console-mounted

STARTING AND OPERATING 479

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.
• 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

(Continued)
WARNING! (Continued)
•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 leav-
ing 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 malfunc-
tion is indicated. Have the brake system serviced by
an authorized dealer immediately.
