2012 RAM CHASSIS CAB instrument cluster

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. If the TOW/HAUL mode is
desired, the switch must be pressed each time the engine
is started.
Torque Converter Clutch
A feature designed to improve fuel economy has been
included in the automatic transmission on your vehicle.
A clutch within the torque converter engages automati-
cally at calibrated speeds. This may result in a slightly
different feeling or response during normal operation in
the upper gears. When the vehicle speed drops or during
some accelerations, the clutch automatically disengages.
NOTE:
• The torque converter clutch will not engage, and the
transmission will not shift to sixth gear, until the transmission fluid and engine coolant are warm [usu-
ally after 1 to 3 miles (1.6 to 4.8 km) of driving].
Because sixth gear is disabled, and engine speed is
higher when the torque converter clutch is not en-
gaged, it may seem as if the transmission is not
shifting properly when cold. This is normal. Using the
Electronic Range Select (ERS) feature, when the trans-
mission is sufficiently warm, will demonstrate that the
transmission is able to shift into and out of Overdrive.
• If the vehicle has not been driven for several days, the
first few seconds of operation after shifting the trans-
mission into gear may seem sluggish. This is due to the
fluid partially draining from the torque converter into
the transmission. This condition is normal and will not
cause damage to the transmission. The torque con-
verter will refill within five seconds after starting the
engine.

FOUR-WHEEL DRIVE OPERATION — IF
EQUIPPED
Four-wheel drive trucks are equipped with either a
manually shifted transfer case or an electronically shifted
transfer case. Refer to the operating instructions for your
transfer case, located in this section for further informa-
tion.
Manually Shifted Transfer Case – If Equipped
The transfer case provides four mode positions.
• Two-wheel drive high range (2H)
• Four-wheel drive high range (4H)
• Neutral (N)
• Four-wheel drive low range (4L)
This transfer case is intended to be driven in the 2H
position for normal street and highway conditions such
as dry, hard surfaced roads. When additional traction is required, the 4H and 4L
positions can be used to lock the front and rear drive-
shafts together and force the front and rear wheels to
rotate at the same speed. This is accomplished by simply
moving the shift lever to the desired positions. The 4H
and 4L positions are intended for loose, slippery road
surfaces only. Driving in the 4H and 4L positions on dry,
hard surfaced roads may cause increased tire wear and
damage to the driveline components.
The “Transfer Case Position Indicator Light” in the
instrument cluster will alert the driver that the vehicle is
in four-wheel drive and that the front and rear drive-
shafts are locked together. This light will illuminate when
the transfer case is shifted into either the 4H or 4L
position. There is no light for the 2H or NEUTRAL
positions.288 STARTING AND OPERATING

2H or 4H ⇔ 4L
With the vehicle rolling at 2 to 3 mph (3 to 5 km/h), shift
the transmission into NEUTRAL. While the vehicle is
coasting at 2 to 3 mph (3 to 5 km/h), shift the transfer
case lever firmly to the desired position. Do not pause in
transfer case NEUTRAL.
NOTE:
• Pausing in transfer case NEUTRAL in vehicles
equipped with an automatic transmission may require
shutting the engine OFF to avoid gear clash while
completing the shift. If difficulty occurs, shift the
transmission into NEUTRAL, hold foot on brake, and
turn the engine OFF. Make shift to the desired mode. • Shifting into or out of 4L is possible with the vehicle
completely stopped, however difficulty may occur due
to the mating clutch teeth not being properly aligned.
Several attempts may be required for clutch teeth
alignment and shift completion to occur. The preferred
method is with the vehicle rolling 2 to 3 mph (3 to
5 km/h). Avoid attempting to engage or disengage 4L
with the vehicle moving faster than 2 to 3 mph (3 to
5 km/h).
• Do not attempt to shift into or from 4L while the
transmission is in gear.
Transfer Case Position Indicator Light
The “Transfer Case Position Indicator Light” in the
instrument cluster is used to alert the driver that the front
axle is fully engaged and all four wheels are driving.

desired position. Refer to “Shifting Procedure” for spe-
cific shifting instructions. The 4WD LOCK and 4WD
LOW positions are designed for loose, slippery road
surfaces only. Driving in the 4WD LOCK and 4WD LOW
positions on dry hard surfaced roads may cause in-
creased tire wear and damage to the driveline compo-
nents.
NOTE: The transfer case NEUTRAL position is selected
by pressing the recessed button located on the lower left
hand corner of the 4WD Control Switch. The transfer case
NEUTRAL position is to be used for recreational towing
only. Refer to “Recreational Towing” in “Starting and
Operating” for further information. Transfer Case Position Indicator Lights
The Transfer Case Position Indicator Lights (4WD and
4LOW) are located in the instrument cluster and indicate
the current and desired transfer case selection. When you
select a different transfer case position, the indicator
lights will do the following:
If All Shift Conditions Are Met:
1. The current position indicator light will turn OFF.
2. The selected position indicator light will flash until the
transfer case completes the shift.
3. When the shift is complete, the indicator light for the
selected position will stop flashing and remain ON.
If One Or More Shift Conditions Are Not Met:
1. The indicator light for the current position will remain
ON.
5 STARTING AND OPERATING 293

If necessary, add fluid to restore to the proper indicated
level. With a clean cloth, wipe any spilled fluid from all
surfaces. Refer to “Fluids, Lubricants, and Genuine
Parts” in “Maintaining Your Vehicle” for further
information.
PARKING BRAKE
Before leaving the vehicle, make sure that the parking
brake is fully applied, the engine is off and the key fob is
removed from the ignition switch. Also, be certain to
leave an automatic transmission in PARK, or manual
transmission in REVERSE or first gear.
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. When the parking brake is applied with the ignition
switch ON, the “Brake Warning Light” in the instrument
cluster will illuminate. Parking Brake Release304 STARTING AND OPERATING

Glass Surfaces
All glass surfaces should be cleaned on a regular basis
with MOPAR  Glass Cleaner or any commercial
household-type glass cleaner. Never use an abrasive type
cleaner. Use caution when cleaning the inside rear win-
dow equipped with electric defrosters or the right rear
quarter window equipped with the radio antenna. Do
not use scrapers or other sharp instruments which may
scratch the elements. When cleaning the rearview mirror,
spray cleaner on the towel or rag that you are using. Do
not spray cleaner directly on the mirror.
Cleaning Plastic Instrument Cluster Lenses
The lenses in front of the instruments in this vehicle are
molded in clear plastic. When cleaning the lenses, care
must be taken to avoid scratching the plastic.
1. Clean with a wet soft rag. A mild soap solution may be
used, but do not use high alcohol content or abrasive
cleaners. If soap is used, wipe clean with a clean damp rag. 2. Dry with a soft cloth.
Seat Belt Maintenance
Do not bleach, dye or clean the belts with chemical
solvents or abrasive cleaners. This will weaken the fabric.
Sun damage can also weaken the fabric.
If the belts need cleaning, use a mild soap solution or
lukewarm water. Do not remove the belts from the car to
wash them. Dry with a soft cloth.
Replace the belts if they appear frayed or worn or if the
buckles do not work properly.
