light Ram 5500 Chassis Cab 2012 Owner's Manual

Automatic Transmission
The “DRIVE” range can be selected when towing. How-
ever, if frequent shifting occurs while in this range, select
“TOW/HAUL” mode or select a lower gear using the
Electronic Range Select (ERS) feature.
NOTE:Using “TOW/HAUL” mode or a lower gear
range while operating the vehicle under heavy operating
conditions will improve performance and extend trans-
mission life by reducing excessive shifting and heat build
up. This action will also provide better engine braking.
The automatic transmission fluid and filter should be
changed if you regularly tow a trailer for more than
45 minutes of continuous operation. Refer to “Mainte-
nance Schedule” for the proper maintenance intervals.
NOTE:Check the automatic transmission fluid level
before towing.
Tow/Haul
To reduce potential for automatic transmission overheat-
ing, turn the “TOW/HAUL” feature ON when driving in
hilly areas, or select a lower gear range (using the
Electronic Range Select (ERS) feature) on more severe
grades.
Electronic Speed Control – If Equipped

Do not use in hilly terrain or with heavy loads.
When using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
Use speed control in flat terrain and with light loads to
maximize fuel efficiency.

Before Plowing
•
Check the hydraulic system for leaks and proper fluid
level.
•Check the mounting bolts and nuts for proper tight-
ness.
•Check the runners and cutting edge for excessive wear.
The cutting edge should be 1/4 to 1/2 in (6 cm to
1.2 cm) above ground in snow plowing position.
•Check that snowplow lighting is connected and func-
tioning properly.
Snowplow Prep Package Model Availability

4. By rotating the wheel wrench clockwise, raise the
vehicle until the wheel just clears the surface.
WARNING!
Raising the vehicle higher than necessary can make
the vehicle unstable and cause a collision. It could
slip off the jack and hurt someone near it. Raise the
vehicle only enough to remove the tire.
5. Remove the wheel nuts and pull the wheel off. Install
the spare wheel and wheel nuts with the cone shaped end
of the nuts toward the wheel on single rear wheel (SRW)
models. On dual rear wheel models (DRW) the lug nuts
are a two-piece assembly with a flat face. Lightly tighten
the nuts. To avoid risk of forcing the vehicle off the jack,
do not fully tighten the nuts until the vehicle has been
lowered.6. Using the wheel wrench, finish tightening the nuts
using a crisscross pattern. The correct nut tightness is
135 ft lbs (183 N·m) torque for single rear wheel (SRW)
models and 145 ft lbs (197 N·m) for dual rear wheel
models. If in doubt about the correct tightness, have them
checked with a torque wrench by your authorized dealer
or at a service station.
WARNING!
A loose tire or jack thrown forward in a collision or
hard stop could injure someone in the vehicle. Al-
ways stow the jack parts and the extra tire and wheel
in the places provided.
7. Install wheel center cap (if equipped) and remove
wheel blocks. Do not install chrome or aluminum wheel
center caps on the spare wheel. This may result in cap
damage.
386 WHAT TO DO IN EMERGENCIES

Preparations For Jump-Start
The battery in your vehicle is located in the front of the
engine compartment, behind the left headlight assembly.
NOTE:The positive battery post is covered with a
protective cap. Lift up on the cap to gain access to the
positive battery post.WARNING!
•Take care to avoid the radiator cooling fan when-
ever the hood is raised. It can start anytime the
ignition switch is on. You can be injured by
moving fan blades.
•Remove any metal jewelry such as watch bands or
bracelets that might make an inadvertent electrical
contact. You could be seriously injured.
•Batteries contain sulfuric acid that can burn your
skin or eyes and generate hydrogen gas which is
flammable and explosive. Keep open flames or
sparks away from the battery.
1. Set the parking brake, shift the automatic transmission
into PARK and turn the ignition to LOCK.
2. Turn off the heater, radio, and all unnecessary electri-
cal accessories.

WHAT TO DO IN EMERGENCIES 393

FREEING A STUCK VEHICLE
If the vehicle becomes stuck in snow, sand, or mud, it can
often be moved by a rocking motion. Move the shift lever
rhythmically between DRIVE/1st and REVERSE while
applying slight pressure to the accelerator.
CAUTION!
•Racing the engine or spinning the wheels may
lead to transmission overheating and failure. Al-
low the engine to idle with the shift lever in
NEUTRAL for at least one minute after every five
rocking-motion cycles. This will minimize over-
heating and reduce the risk of transmission failure
during prolonged efforts to free a stuck vehicle.
(Continued)
CAUTION! (Continued)
•When “rocking” a stuck vehicle by moving be-
tween DRIVE/1st and REVERSE, do not spin the
wheels faster than 15 mph (24 km/h), or drivetrain
damage may result.
•Revving the engine or spinning the wheels too fast
may lead to transmission overheating and failure.
It can also damage the tires. Do not spin the
wheels above 30 mph (48 km/h) while in gear (no
transmission shifting occurring).
396 WHAT TO DO IN EMERGENCIES

ONBOARD DIAGNOSTIC SYSTEM (OBD II)
Your vehicle is equipped with a sophisticated onboard
diagnostic system called OBD II. This system monitors
the performance of the emissions, engine, and automatic
transmission control systems. When these systems are
operating properly, your vehicle will provide excellent
performance and fuel economy, as well as engine emis-
sions well within current government regulations.
If any of these systems require service, the OBD II system
will turn on the “Malfunction Indicator Light (MIL).” It
will also store diagnostic codes and other information to
assist your service technician in making repairs. Al-
though your vehicle will usually be drivable and not
need towing, see your authorized dealer for service as
soon as possible.CAUTION!
•Prolonged driving with the MIL on could cause
further damage to the emission control system. It
could also affect fuel economy and drivability. The
vehicle must be serviced before any emissions
tests can be performed.
•If the MIL is flashing, while the engine is running,
severe catalytic converter damage and power loss
will soon occur. Immediate service is required.
Loose Fuel Filler Cap Message
If the vehicle diagnostic system determines
that the fuel filler cap is loose, improperly
installed, or damaged, a loose gascap indicator
will display in the EVIC telltale display area.
Refer to “Electronic Vehicle Information Center (EVIC) in
“Understanding Your Instrument Panel” for further in-
formation. Tighten the fuel filler cap properly and press
