RADIO OPERATION AND MOBILE PHONES

Under certain conditions, the mobile phone being
on in your vehicle can cause erratic or noisy
performance from your radio. This condition may be
lessened or eliminated by relocating the mobile
phone antenna. This condition is not harmful to
the radio. If your radio performance does not
satisfactorily “clear” by the repositioning of the
antenna, it is recommended that the radio volume
be turned down or off during mobile phone
operation when not using Uconnect (if equipped).

SAFETY FEATURES
ANTI-LOCK BRAKE SYSTEM (ABS)
The ABS provides increased vehicle stability
and brake performance under most braking
conditions. The system automatically prevents
wheel lock, and enhances vehicle control during
braking.

The ABS performs a self-check cycle to ensure
that the ABS is working properly each time the
vehicle is started and driven. During this
self-check, you may hear a slight clicking sound
as well as some related motor noises.

ABS is activated during braking when the
system detects one or more wheels are
beginning to lock. Road conditions such as ice,
snow, gravel, bumps, railroad tracks, loose
debris, or panic stops may increase the
likelihood of ABS activation(s).You also may experience the following normal
characteristics when ABS activates:
The ABS motor noise or clicking sounds (you
may continue to hear for a short time after
the stop)
Brake pedal pulsations
A slight drop of the brake pedal at the end of
the stop

ABS is designed to function with the Original
Equipment Manufacturer (OEM) tires. Modification
may result in degraded ABS performance.

WARNING!
The ABS contains sophisticated electronic
equipment that may be susceptible to inter -
ference caused by improperly installed or
high output radio transmitting equipment.
This interference can cause possible loss of
anti-lock braking capability. Installation of
such equipment should be performed by
qualified professionals.

Pumping of the Anti-Lock Brakes will diminish
their effectiveness and may lead to a collision.
Pumping makes the stopping distance longer.
Just press firmly on your brake pedal when you
need to slow down or stop.

The ABS cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase braking or steering efficiency
beyond that afforded by the condition of the
vehicle brakes and tires or the traction
afforded.
The ABS cannot prevent collisions,
including those resulting from excessive
speed in turns, following another vehicle
too closely, or hydroplaning.
The capabilities of an ABS equipped vehicle
must never be exploited in a reckless or
dangerous manner that could jeopardize
the user’s safety or the safety of others.

TIRE PRESSURE MONITORING
S
YSTEM (TPMS)
(Vehicles Under 10K Gross Vehicle Weight
Rating (GVWR) Only)
The Tire Pressure Monitoring System (TPMS)
will warn the driver of a low tire pressure based
on the vehicle recommended cold placard
pressure.
NOTE:
The TPMS Warning 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 instrument
cluster will display a graphic showing the pres -
sure values of each tire with the low tire pres -
sure values in a different color, or the Uconnect
radio will display a TPMS message. When this
occurs you must increase the tire pressure to
the recommended cold placard pressure in
order for the TPMS Warning Light to turn off.
The tire pressure will vary with temperature
by about 1 psi (7 kPa) for every 12°F (6.5°C).
This means that when the outside temperature
decreases, the tire pressure will decrease.
Tire pressure should always be set based on
cold inflation tire pressure. This is defined as the tire pressure after the vehicle has not been
driven for at least three hours, or driven less
than 1 mile (1.6 km) after a three hour period.
The cold tire inflation pressure must not exceed
the maximum inflation pressure molded into
the tire sidewall. The tire pressure will also
increase as the vehicle is driven — this is normal
and there should be no adjustment for this
increased pressure.
See
Úpage 406 on how to properly inflate the
vehicle’s tires.
The TPMS will warn the driver of a low tire
pressure if the tire pressure falls below the
low-pressure warning limit for any reason,
including low temperature effects and natural
pressure loss through the tire.
The TPMS will continue to warn the driver of low
tire pressure as long as the condition exists,
and will not turn off until the tire pressure is
at or above the recommended cold placard
pressure. Once the low TPMS Warning Light
illuminates, you must increase the tire pressure
to the recommended cold placard pressure in
order for the TPMS Warning Light to turn off.
The system will automatically update and the
TPMS Warning Light will turn off once the
system receives the updated tire pressures. 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.
NOTE:
When filling warm tires, the tire pressure may
need to be increased up to an additional 4 psi
(28 kPa) above the recommended cold placard
pressure in order to turn the TPMS Warning
Light off.

For example, your vehicle may have a
recommended cold (parked for more than
three hours) placard pressure of 30 psi
(207 kPa). If the ambient temperature is 68°F
(20°C) and the measured tire pressure is 27 psi
(186 kPa), a temperature drop to 20°F (-7°C) will
decrease the tire pressure to approximately
23 psi (158 kPa). This tire pressure is sufficiently
low enough to turn on the TPMS Warning Light.
Driving the vehicle may cause the tire pressure to
rise to approximately 27 psi (186 kPa), but the
TPMS Warning Light will still be on. In this
situation, the TPMS Warning Light will turn off
only after the tires are inflated to the vehicle’s
recommended cold placard pressure value

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 TPMS 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 TPMS
sensors.

A system fault may occur due to an incorrect
TPMS sensor location condition. When a system
fault occurs due to an incorrect TPMS sensor
location, the Tire Pressure Monitoring System
Warning 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 instrument
cluster will display a “Tire Pressure Temporarily
Unavailable” message in place of the tire
pressure display screen. 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
System Indicator Light will no longer flash and the
tire pressure display screen will be displayed
showing the tire pressure values in the correct
locations.

Vehicles With Non-Matching Full Size Spare Or
Compact Spare
The non-matching full size spare or compact
spare tire does not have a TPMS sensor.
Therefore, the TPMS will not monitor the
pressure in the non-matching full size spare
or compact spare tire.
If you install the non-matching full size spare
or compact spare tire in place of a road tire
that has a pressure below the low-pressure
warning limit, upon the next ignition switch
cycle, the TPMS Warning Light and a “LOW
TIRE” message will remain on and a chime
will sound. In addition, the graphic in the
instrument cluster will still display a pressure
value in a different color and an “Inflate to
XX” message.
After driving the vehicle for up to 20 minutes
above 15 mph (24 km/h), the TPMS Warning
Light will flash on and off for 75 seconds and
then remain on solid. In addition, the instru -ment cluster will display a "SERVICE TPM
SYSTEM" message for a minimum of
five seconds and then display dashes (- -) in
place of the pressure value.

For each subsequent ignition switch cycle, a
chime will sound, the TPMS Warning Light will
flash on and off for 75 seconds and then
remain on solid, and the instrument cluster will
display a "SERVICE TPM SYSTEM" message for
a minimum of five seconds and then display
dashes (- -) in place of the pressure value.

Once you repair or replace the original road
tire and reinstall it on the vehicle in place of
the non matching full size spare or compact
spare, the TPMS will update automatically.
In addition, the TPMS Warning Light will turn
off and the graphic in the instrument cluster
will display a new pressure value instead of
dashes (- -), as long as no tire pressure is
below the low-pressure warning limit in any of
the four active road tires. 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.

Trailer Tire Pressure Monitoring System
(TTPMS) — If Equipped
The Trailer Tire Pressure Monitoring System
(TTPMS) is a feature that displays the trailer tire
pressure values and warns the driver of a low
tire pressure event based on the drivers set
target tire pressure value, through TTPMS
settings found in the radio.

The TTPMS monitors the pressure of each tire
and warns the driver through the instrument
cluster, when either a low tire pressure condition
falls below 25% of the driver’s set pressure or if a
system malfunction occurs. The instrument
cluster will display the actual tire pressure or
dashes for each of the trailer tires in the correct
trailer position, based on trailer configuration.
The TTPMS can support up to 12 trailer tires per
configured trailer on up to four configurable
trailers
Ú
page 228. Trailer Tire Pressure Monitoring System

Trailer Tire Pressure Sensor Pairing
In order use this feature, the provided tire
pressure sensors must be installed in the
desired trailer tires and the sensors must be
paired to the truck. If the target trailer requires
more than the provided four sensors, additional
sensors can be purchased at an authorized
Ram dealership.
With the sensors installed and the trailer near
or connected to your Ram truck, initiate the
pairing process by entering the settings menu in
the radio and select trailer. Select the desired
trailer profile to pair to, open the “Tire Pressure”
menu, and hit “Setup All Tires” Ú page 228.NOTE:
The Vehicle may not be driven until the pairing
process is complete.

Follow the on screen prompts to select the
number of axles (1 - 3), the number of trailer
tires (2, 4, 6, 8, or 12), and the set trailer tire
pressure. The range is selectable anywhere
between 25-125 psi (172-862 kPa).
Once psi (kPa) is programmed, the pairing
screen appears. Tire sensors must be paired in
order shown. Starting with Tire 1, deflate tire by
5 psi (34 kPa) and wait for a horn chirp. It may
take up to three minutes for the chirp to occur,
indicating that the sensor has paired. Repeat
process on each tire, in order, until complete.
Do not exit the pairing screen until process is
complete. If pairing was unsuccessful, a double
horn chirp will sound, and a prompt on the
touchscreen will allow you to retry the
procedure; “Retry” will only appear when setup
fails. Each tire must be successfully paired
during a single pairing process to receive the
success screen.
NOTE:
If the pairing process times out after three
minutes of no communication with a sensor, a
double horn chirp will occur indicating the
pairing has failed and a message will display on
the radio indicating the process was unsuc -
cessful. Under certain circumstances, the double horn chirp may continue to happen
every three minutes indicating the failed
pairing. If this happens, the horn chirping may
be canceled by cycling the ignition button OFF
and then back to ON/RUN position.
Tire Pressure Monitoring System Low Pressure
Warnings
When a low tire pressure in one or more of the
active road tires is detected, the instrument
cluster will display a message stating “Trailer
Tire Pressure Low”. The instrument cluster will
then display the TTPMS graphic showing the
pressure values of each tire with the low tire
pressure values in a different color.
Should this occur, you should stop as soon as
possible and inflate the tires with a low pressure
condition (those in a different color in the
instrument cluster graphic) to the customer
programmed target tire pressure value as
shown at the top of the TTPMS instrument
cluster graphic. Once the tire(s) are inflated, the
system will automatically update the graphic
display in the instrument cluster, returning to its
original color. The vehicle may need to be driven
for up to 10 minutes above 15 mph (24 km/h)
in order for the TTPMS to receive the updated
information.Service TTPMS Warning
If a system fault is detected, the instrument
cluster will display a “Trailer Tire Pressure
System Service Required” message for a
minimum of five seconds.

Once the system fault is corrected the "Trailer
Tire Pressure System Service Required" message
will no longer be displayed. The vehicle may need
to be driven for up to 10 minutes above 15 mph
(24 km/h) in order for the TTPMS to receive the
trailer tire pressure information.

Trailer Sensors Detected Do Not Match Active
Trailer
The “Trailer Sensors Detected Do Not Match
Active Trailer” message will be displayed in the
instrument cluster when the trailer sensors
being received by the TTPMS module do not
match the trailer sensors paired to the current
trailer number selected. This message will be
displayed when the sensors being received
completely match the sensors paired to another
trailer number configured in the TTPMS module.
To correct this condition, the correct trailer
number must be selected in the radio
Úpage 228.
Tire Fill Alert — If Equipped
This feature notifies the user when the placard
tire pressure is attained while inflating or
deflating the tire.
The customer may choose to disable or enable
the Tire Fill Alert feature through use of the
customer settings in the radio. NOTE:
Only one tire can be filled at a time when
using the Tire Fill Alert system.

The Tire Fill Alert feature cannot be entered if
an existing TPMS fault is set to “active” or if the
system is in deactivation mode (if equipped).

The system will be activated when the TPMS
receiver module detects a change in tire
pressure. The ignition must be in the RUN
mode, with the transmission in PARK (P).
NOTE:
It is not required to have the engine running to
enter Tire Fill Alert mode.
The hazard lamps will come on to confirm the
vehicle is in Tire Fill Alert mode.
If the hazard lamps do not come on while
inflating the tire, the TPMS sensor may be in a
null spot preventing the TPMS sensor signal
from being received. In this case, the vehicle
may need to be moved either forward or
backward slightly to exit the null spot. When Tire Fill Alert mode is entered, the tire
pressure display screen will be displayed in the
instrument cluster.
Operation:The horn will chirp once to let the user know
when to stop filling the tire, when it reaches
recommended pressure.
The horn will chirp three times if the tire is
overfilled and will continue to chirp every
five seconds if the user continues to inflate
the tire.
The horn will chirp once again when enough
air is let out to reach proper inflation level.
The horn will also chirp three times if the tire
is then underinflated and will continue to
chirp every five seconds if the user continues
to deflate the tire.
