tires Ram 1500 2014 Workshop Manual

A system fault can occur due to any of the following:
1. Signal interference due to electronic devices or drivingnext to facilities emitting the same radio frequencies as
the TPM sensors.
2. Installing aftermarket window tinting that contains materials that may block radio wave signals.
3. Accumulation of snow or ice around the wheels or wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM sensors.
Vehicles with Full Size Spare
1. The matching full size spare wheel and tire assembly has a TPM sensor that can be monitored by the TPMS.
2. If you install the full size spare in place of a road tire that has a pressure below the low-pressure warning limit, upon the next ignition switch cycle, a chime will
sound, a “LOW TIRE PRESSURE” message will be
displayed, and the “Tire Pressure Monitoring Telltale
Light” will turn ON. An
Inflate to XXmessage will
also be displayed.
3. Driving the vehicle for up to 20 minutes above 15 mph (24 km/h) will turn off the “Tire Pressure Monitoring
Telltale Light” and “LOW TIRE PRESSURE” message,
as long as no tire pressure is below the low-pressure
warning limit in any of the four active road tires.
Premium System — If Equipped
The Tire Pressure Monitor System (TPMS) uses wireless
technology with wheel rim mounted electronic sensors to
monitor tire pressure levels. Sensors mounted to each
wheel as part of the valve stem transmit tire pressure
readings to the receiver module.
5
STARTING AND OPERATING 571

NOTE:It is particularly important for you to check the
tire pressure in all of the tires on your vehicle monthly
and to maintain the proper pressure.
The TPMS consists of the following components:
• Receiver module,
• Four TPM sensors,
• Various TPMS messages, which display in the Elec-
tronic Vehicle Information Center (EVIC), and
• TPM Telltale Light
The matching full size spare wheel and tire assembly (if
equipped) has a TPM sensor. The full size spare can be
used in place of any of the four road tires. A spare with a
pressure below the low-pressure limit will not cause the
“Tire Pressure Monitoring Telltale Light” to illuminate or
the chime to sound.Tire Pressure Monitoring Low Pressure Warnings
The “Tire Pressure Monitoring Telltale Light” will
illuminate in the instrument cluster and a chime
will sound when tire pressure is low in one or more of the
four active road tires. In addition, the EVIC will display
a “LOW TIRE PRESSURE” message for a minimum of
five seconds and a graphic showing the pressure values
of each tire with the low tire pressure values flashing or
in a different color. An Inflate to XXmessage will also be
displayed.
572 STARTING AND OPERATING

Should this occur, you should stop as soon as possible
and inflate the tires with a low pressure condition (those
flashing or in a different color in the EVIC graphic) to the
vehicle’s recommended cold placard pressure inflation
value as shown in theInflate to XXmessage. Once the
system receives the updated tire pressures, the system will automatically update, the graphic display in the
EVIC will stop flashing or return to it’s original color, and
the “Tire Pressure Monitoring Telltale Light” will turn
off. The vehicle may need to be driven for up to 20
minutes above 15 mph (24 km/h) in order for the TPMS
to receive this information.
Service TPMS Warning
If a system fault is detected, the “Tire Pressure Monitor-
ing Telltale Light” will flash on and off for 75 seconds and
then remain on solid. The system fault will also sound a
chime. In addition, the EVIC will display a
SERVICE
TPM SYSTEM message for a minimum of five seconds
and then display dashes (- -) in place of the pressure
value to indicate which sensor is not being received.

STARTING AND OPERATING 573

If the ignition switch is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault
no longer exists, the “Tire Pressure Monitoring Telltale
Light” will no longer flash, and theSERVICE TPMSYSTEM
message will no longer display, and a pressure
value will display in place of the dashes. A system fault
can occur due to any of the following:
1. Signal interference due to electronic devices or driving next to facilities emitting the same radio frequencies as
the TPM sensors.
2. Installing aftermarket window tinting that contains materials that may block radio wave signals.
3. Accumulation of snow or ice around the wheels or wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM sensors.

Tire Pressure Information System (TPIS) 3500
Series Trucks
Your vehicle may be equipped with a Tire Pressure
Information System (TPIS).
The Tire Pressure Information System (TPIS) uses wire-
less technology with wheel rim mounted electronic sen-
sors to transmit tire pressure levels. Sensors mounted to
each wheel as part of the valve stem transmit tire
pressure readings to the receiver module.
NOTE:
It is particularly important for you to check the
tire pressure in all of the tires on your vehicle monthly
and to maintain the proper pressure.
5
STARTING AND OPERATING 575

The TPIS consists of the following components:
•Receiver module
• Four TPM sensors (Single Rear Wheel (SRW) applica-
tions)
• Six TPM sensors (Dual Rear Wheel (DRW) applica-
tions)
• Pressure display in the Electronic Vehicle Information
Center (EVIC)
The TPIS system will display all four (Single Rear Wheel
(SRW) applications) or six (Dual Rear Wheel (DRW)
applications) tire pressure values EVIC display.
If a system fault is detected, the EVIC will display a
SERVICE TPM SYSTEM message for a minimum of five
seconds and then display dashes (- -) in place of the
pressure value to indicate which sensor is not being
received. If the ignition switch is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault
no longer exists, the
SERVICE TPM SYSTEM message
will no longer be displayed, and a pressure value will
display in place of the dashes. A system fault can occur
due to any of the following:
• Signal interference due to electronic devices or driving
next to facilities emitting the same radio frequencies as
the TPM sensors.
• Installing aftermarket window tinting that contains
materials that may block radio wave signals.
• Accumulation of snow or ice around the wheels or
wheel housings.
• Using tire chains on the vehicle.
• Using wheels/tires not equipped with TPM sensors.
576 STARTING AND OPERATING

This label contains the month and year of manufacture,
Gross Vehicle Weight Rating (GVWR), Gross Axle Weight
Rating (GAWR) front and rear, and Vehicle Identification
Number (VIN). A Month-Day-Hour (MDH) number is
included on this label and indicates the Month, Day and
Hour of manufacture. The bar code that appears on the
bottom of the label is your VIN.
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total permissible weight of your vehicle
including driver, passengers, vehicle, options and cargo.
The label also specifies maximum capacities of front and
rear axle systems (GAWR). Total load must be limited so
GVWR and front and rear GAWR are not exceeded.
Payload
The payload of a vehicle is defined as the allowable load
weight a truck can carry, including the weight of the
driver, all passengers, options and cargo.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum permissible load on the front
and rear axles. The load must be distributed in the cargo
area so that the GAWR of each axle is not exceeded.
Each axle GAWR is determined by the components in the
system with the lowest load carrying capacity (axle,
springs, tires or wheels). Heavier axles or suspension
components sometimes specified by purchasers for in-
creased durability does not necessarily increase the vehi-
cle’s GVWR.
Tire Size
The tire size on the Vehicle Certification Label represents
the actual tire size on your vehicle. Replacement tires
must be equal to the load capacity of this tire size.
Rim Size
This is the rim size that is appropriate for the tire size
listed.

WARNING!
Improper towing can lead to a collision. Follow these
guidelines to make your trailer towing as safe as
possible:
•Make certain that the load is secured in the trailer
and will not shift during travel. When trailering
cargo that is not fully secured, dynamic load shifts
can occur that may be difficult for the driver to
control. You could lose control of your vehicle and
have a collision.
• When hauling cargo or towing a trailer, do not
overload your vehicle or trailer. Overloading can
cause a loss of control, poor performance or dam-
age to brakes, axle, engine, transmission, steering,
suspension, chassis structure or tires.
(Continued)
WARNING! (Continued)
•Safety chains must always be used between your
vehicle and trailer. Always connect the chains to
the hook retainers of the vehicle hitch. Cross the
chains under the trailer tongue and allow enough
slack for turning corners.
• Vehicles with trailers should not be parked on a
grade. When parking, apply the parking brake on
the tow vehicle. Put the tow vehicle transmission in
PARK. For four-wheel drive vehicles, make sure
the transfer case is not in NEUTRAL. Always,
block or chockthe trailer wheels.
• GCWR must not be exceeded.

WARNING!(Continued)
•Total weight must be distributed between the tow
vehicle and the trailer such that the following four
ratings are not exceeded:
1. GVWR
2. GTW
3. GAWR
4. Tongue weight rating for the trailer hitch uti-
lized.
Towing Requirements — Tires
• Do not attempt to tow a trailer while using a compact
spare tire.
• Proper tire inflation pressures are essential to the safe
and satisfactory operation of your vehicle. Refer to
“Tires – General Information” in “Starting and Oper-
ating” for proper tire inflation procedures.
• Check the trailer tires for proper tire inflation pres-
sures before trailer usage.
• Check for signs of tire wear or visible tire damage
before towing a trailer. Refer to “Tires – General
Information” in “Starting and Operating” for the
proper inspection procedure.
• When replacing tires, refer to “Tires – General Infor-
mation” in “Starting and Operating” for proper tire
replacement procedures. Replacing tires with a higher
load carrying capacity will not increase the vehicle’s
GVWR and GAWR limits.
602 STARTING AND OPERATING

9. If the trailer wheels lockup (indicated by squealingtires), reduce the GAIN setting; if the trailer wheels
turn freely, increase the GAIN setting.
Repeat steps 8 and 9 until the GAIN setting is at a point
just below trailer wheel lockup. If towing a heavier trailer, trailer wheel lockup may not be attainable even
with the maximum GAIN setting of 10.
