2012 Ram 5500 Chassis Cab wheel torque

6. 4 LOW
This light alerts the driver that the vehicle is in
the four-wheel drive LOW mode. The front and
rear driveshafts are mechanically locked to-
gether forcing the front and rear wheels to
rotate at the same speed. Low range provides a greater
gear reduction ratio to provide increased torque at the
wheels.
7. Electronic Throttle Control (ETC) Light
This light informs you of a problem with the
Electronic Throttle Control (ETC) system. The
light will come on when the ignition is first
turned to ON/RUN and remain on briefly as a
bulb check. If the light does not come on during starting,
have the system checked by an authorized dealer.
If a problem is detected, the light will come on while the
engine is running. Cycle the ignition key when thevehicle has completely stopped and the shift lever is
placed in the PARK position, the light should turn off.
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 and you may experience reduced performance,
an elevated/rough idle or engine stall and your vehicle
may require towing.
For vehicles equipped with a premium cluster this indi-
cator will display in the Electronic Vehicle Information
Center (EVIC). Refer to ”Electronic Vehicle Information
Center (EVIC) — If Equipped” for further information.
8. 4WD Indicator
This light indicates the vehicle is in four-wheel
drive and 4LOCK. 4WD allows all four wheels
to receive torque from the engine simultane-
ously.

25. Front Fog Light Indicator — If Equipped
This indicator will illuminate when the front fog
lights are on.
26. Anti-Lock Brake (ABS) Light
This light monitors the Anti-lock Brake System
(ABS). The light will turn on when the ignition
switch is turned to the ON/RUN position and
may stay on for as long as four seconds.
If the ABS light remains on or turns on while driving, it
indicates that the anti-lock portion of the brake system is
not functioning and that service is required. However,
the conventional brake system will continue to operate
normally if the BRAKE warning light is not on.
If the ABS light is on, the brake system should be serviced
as soon as possible to restore the benefits of anti-lock
brakes. If the ABS light does not turn on when the
ignition switch is turned to the ON/RUN position, have
the light inspected by an authorized dealer.27. Transmission Temperature Warning Light
This light indicates that there is excessive trans-
mission fluid temperature that might occur
with severe usage such as trailer towing. It may
also occur when operating the vehicle in a high
torque converter slip condition, such as 4-wheel-drive
operation (e.g., snow plowing, off-road operation). If this
light comes on, stop the vehicle and run the engine at idle
or faster with the transmission in NEUTRAL until the
light goes off.
CAUTION!
Continuous driving with the Transmission Tempera-
ture Warning Light illuminated will eventually cause
severe transmission damage or transmission failure.

•SERV 4WD
The SERV 4WD light monitors the electric shift
4WD system. If the SERV 4WD light stays on or
comes on during driving, it means that the
4WD system is not functioning properly and
that service is required.
•Electronic Stability Control (ESC) OFF Indicator
Light — If Equipped
This light indicates the Electronic Stability Con-
trol (ESC) is off.
•Transmission Temperature Light
This light indicates that there is excessive trans-
mission fluid temperature that might occur
with severe usage such as trailer towing. It may
also occur when operating the vehicle in a high
torque converter slip condition, such as 4-wheel-drive
operation (e.g., snow plowing, off- road operation). If thislight comes on, stop the vehicle and run the engine at idle
or faster, with the transmission in NEUTRAL until the
light goes off.
CAUTION!
Continuous driving with the Transmission Tempera-
ture Indicator illuminated will eventually cause se-
vere transmission damage or transmission failure.
WARNING!
If the Transmission Temperature Warning Light is
illuminated and you continue operating the vehicle,
in some circumstances you could cause the fluid to
boil over, come in contact with hot engine or exhaust
components and cause a fire.

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

1. Tighten the wheel nuts in the numbered sequence to a
snug fit.
2. Retighten the wheel nuts in the same sequence to the
torques listed in the table. Go through the sequence a
second time to verify that specific torque has been
achieved. Retighten to specifications at 100 miles
(160 km) and after 500 miles (800 km).
It is recommended that wheel stud nuts be kept torqued
to specifications at all times. Torque wheel stud nuts to
specifications at each lubrication interval.Wheel Nut Torque
All wheel nuts should be tightened occasionally to elimi-
nate the possibility of wheel studs being sheared or the
bolt holes in the wheels becoming elongated. This is
especially important during the first few hundred miles/
kilometers of operation to allow the wheel nuts to
become properly set. All nuts should first be firmly
seated against the wheel. The nuts should then be
tightened to recommended torque. Tighten the nuts to
final torque in increments. Progress around the bolt
circle, tightening the nut opposite to the nut just previ-
ously tightened until final torque is achieved. Recom-
mended torques are shown in the following chart.
