2013 Ram 2500 automatic transmission

•Cabin heating or cooling is in process and an accept-
able cabin temperature has not been achieved
• HVAC is set to full defrost mode at a high blower
speed
• Engine has not reached normal operating temperature
• Battery discharged
• The transmission is not in DRIVE
• Hood is open
• Vehicle is in 4LO transfer case mode
Other factors which can inhibit AutoStop include: fuel
level, accelerator pedal input, engine temp too high and
steering angle.
It may be possible for the vehicle to be driven several
times without the STOP/START system going into a
STOP/START READY state under more extreme condi-
tions of the items listed above.To Start The Engine While In Autostop Mode
While in DRIVE the engine will start when the brake
pedal is released or the throttle pedal is depressed. The
transmission will automatically reengage upon engine
restart. During this transition the brakes will hold the
vehicle to avoid undesired vehicle movement.
Conditions that will cause the engine to start automati-
cally while in Autostop mode
The Engine Will Start Automatically When:
• The transmission selector is moved from DRIVE to
REVERSE or NEUTRAL
• To maintain cabin temperature near the HVAC settings
• HVAC is set to full defrost mode
• Autostop time exceeds 5 minutes
• Battery voltage drops too low

WARNING!
Remember to disconnect the engine block heater
cord before driving. Damage to the 110-115 Volt
electrical cord could cause electrocution.
AUTOMATIC TRANSMISSION
CAUTION!
Damage to the transmission may occur if the follow-
ing precautions are not observed:
•Shift into PARK only after the vehicle has come to
a complete stop.
• Shift into or out of REVERSE only after the vehicle
has come to a complete stop and the engine is at
idle speed.
(Continued)
CAUTION! (Continued)
•Do not shift between PARK, REVERSE, NEU-
TRAL, or DRIVE when the engine is above idle
speed.
• Before shifting into any gear, make sure your foot
is firmly pressing the brake pedal.
NOTE: You must press and hold the brake pedal while
shifting out of PARK.

Eight-Speed Automatic Transmission – If
Equipped
Your vehicle is equipped with a state of the art, fuel
efficient eight-speed transmission. The electronic shifter
control is located on the instrument panel. The transmis-
sion gear range (PRND) is displayed both above the
shifter control and in the Electronic Vehicle Information
Center (EVIC). To select a gear range, simply rotate the
shifter control. You must press the brake pedal to shift the
transmission out of PARK (see Brake/Transmission Shift
Interlock System). You must also press the brake pedal to
shift from NEUTRAL into DRIVE or REVERSE, when the
vehicle is stopped or moving at low speeds. To shift past
multiple gear ranges at once (such as Park to Drive),
simply rotate the shifter control to the appropriate detent.
Select the DRIVE range for normal driving.
The electronically-controlled transmission provides a
precise shift schedule. The transmission electronics are
self-calibrating; therefore, the first few shifts on a newvehicle may be somewhat abrupt. This is a normal
condition, and precision shifts will develop within a few
hundred miles (kilometers).
Only shift from DRIVE to PARK or REVERSE when the
accelerator pedal is released and the vehicle is stopped.
Be sure to keep your foot on the brake pedal when
shifting between these gears.
The transmission shifter control has only PARK, RE-
VERSE, NEUTRAL, and DRIVE positions. Manual down-
shifts can be made using the Electronic Range Select
(ERS) switches (described later in this section). Pressing
the GEAR-/GEAR+ switches (on the steering wheel)
while in the DRIVE position will select the highest
available transmission gear, and will display that gear in
the instrument cluster as 8, 7, 6, 5, 4, 3, 2, 1.

NEUTRAL
Use this range when the vehicle is standing for prolonged
periods with the engine running. The engine may be
started in this range. Apply the parking brake and shift
the transmission into PARK if you must leave the vehicle.
WARNING!
Do not coast in NEUTRAL and never turn off the
ignition to coast down a hill. These are unsafe
practices that limit your response to changing traffic
or road conditions. You might lose control of the
vehicle and have a collision.
CAUTION!
Towing the vehicle, coasting, or driving for any other
reason with the transmission in NEUTRAL can cause

severe transmission damage. Refer to “Recreational
Towing” in “Starting And Operating” and “Towing A
Disabled Vehicle” in “What To Do In Emergencies”
for further information.
DRIVE
This range should be used for most city and highway
driving. It provides the smoothest upshifts and down-
shifts, and the best fuel economy. The transmission
automatically upshifts through all forward gears. The
DRIVE position provides optimum driving characteris-
tics under all normal operating conditions.
When frequent transmission shifting occurs (such as
when operating the vehicle under heavy loading condi-
tions, in hilly terrain, traveling into strong head winds, or
while towing heavy trailers), use the Electronic Range
Select (ERS) switches (refer to Electronic Range Select
360 STARTING AND OPERATING

4. Wait approximately 30 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is nolonger detected, the transmission will return to normal
operation.
NOTE: Even if the transmission can be reset, we recom-
mend that you visit your authorized dealer at your
earliest possible convenience. Your authorized dealer has
diagnostic equipment to determine if the problem could
recur.
If the transmission cannot be reset, authorized dealer
service is required.
Electronic Range Select (ERS) Operation – 8 Speed
Transmission
The Electronic Range Select (ERS) switches allow the
driver to limit the highest available gear when the transmission is in DRIVE. For example, if you shift the
transmission into 3 (third gear), the transmission will not
shift above third gear (except to prevent engine over-
speed), but will shift down into second and first gears
normally.
You can switch between DRIVE and ERS mode at any
vehicle speed. When the shifter control is in the DRIVE
position, 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
maintain that gear as the top available gear. Once in ERS
mode, tapping the GEAR- or GEAR+ switch will change
the top available gear.
362 STARTING AND OPERATING

The “TOW/HAUL Indicator Light” will illuminate in the
instrument cluster to indicate that TOW/HAUL mode
has been activated. Pressing the switch a second time
restores normal operation. Normal operation is alwaysthe default at engine start-up. If TOW/HAUL mode is
desired, the switch must be pressed each time the engine
is started.
Six–Speed Automatic Transmission If Equipped
— 1500 Models Only
The transmission gear position display (located in the
instrument cluster) indicates the transmission gear range.
The shift lever is mounted either on the right side of the
steering column (if equipped) or on the console (if
equipped). You must press the brake pedal to move the
shift lever out of PARK (refer to “Brake/Transmission
Shift Interlock System” in this section). To drive, move
the shift lever from PARK or NEUTRAL to the DRIVE
position. Pull the shift lever toward you when shifting
into REVERSE or PARK, or when shifting out of PARK
(column shift only).
The electronically-controlled transmission provides a
precise shift schedule. The transmission electronics are

WARNING!
Do not coast in NEUTRAL and never turn off the
ignition to coast down a hill. These are unsafe
practices that limit your response to changing traffic
or road conditions. You might lose control of the
vehicle and have a collision.
CAUTION!
Towing the vehicle, coasting, or driving for any other
reason with the transmission in NEUTRAL can cause
severe transmission damage. Refer to “Recreational
Towing” in “Starting And Operating” and “Towing A
Disabled Vehicle” in “What To Do In Emergencies”
for further information.DRIVE
This range should be used for most city and highway
driving. It provides the smoothest upshifts and down-
shifts, and the best fuel economy. The transmission
automatically upshifts through underdrive first and sec-
ond gears, direct third gear and overdrive fourth and
fifth gears. The DRIVE position provides optimum driv-
ing characteristics under all normal operating conditions.
To access all six available gears, you must use the
Electronic Range Select (ERS) shift control, described
below.
When frequent transmission shifting occurs (such as
when operating the vehicle under heavy loading condi-
tions, in hilly terrain, traveling into strong head winds, or
while towing heavy trailers), use the Electronic Range
Select (ERS) shift control (refer to “Electronic Range
Select (ERS) Operation)” in this section) to select a lower
gear range. Under these conditions, using a lower gear

Electronic Range Select (ERS) Operation -
Six-Speed Transmission
The Electronic Range Select (ERS) shift control allows the
driver to limit the highest available gear when the shift
lever is in the DRIVE position. For example, if you shift
the transmission into 3 (third gear), the transmission will
not shift above third gear, but will shift down into second
and first gears normally.
Use of ERS (or TOW/HAUL mode) also enables an
additional underdrive gear which is not normally used
during through-gear accelerations. This additional gear
can improve vehicle performance and cooling capability
when towing a trailer on certain grades. In ERS mode,
gears 1 though 3 are underdrive gears, and ERS 4 is direct
drive. ERS 5 and 6 (Overdrive gears) are the same as the
normal fourth and fifth gears.You can switch between DRIVE and ERS mode at any
vehicle speed. When the shift lever is in the DRIVE
position, the transmission will operate automatically,
shifting between all available gears. Tapping the ERS (-)
switch (column shift) or tapping the shift lever to the left
(-) (console shift) will activate ERS mode, display the
current gear in the instrument cluster, and maintain that
gear as the top available gear. For example, if you are in
DRIVE and are in third (direct) gear, when you tap the
shift lever/switch one time in the (-) direction, the
display will show 4 (ERS 4 is direct gear). Another tap
down (-) will shift the transmission down to ERS 3 (the
added underdrive gear). Once in ERS mode, tapping ERS
(-) or (+) will change the top available gear.
