warning DODGE CHALLENGER 2018 Repair Manual

The BSM system will not alert you of objects that are
traveling in the opposite direction of the vehicle in adjacent
lanes.
WARNING!
The Blind Spot Monitoring system is only an aid to
help detect objects in the blind spot zones. The BSM
system is not designed to detect pedestrians, bicyclists,
or animals. Even if your vehicle is equipped with the
BSM system, always check your vehicle’s mirrors,
glance over your shoulder, and use your turn signal
before changing lanes. Failure to do so can result in
serious injury or death.Stationary Objects
Opposing Traffic
136 SAFETY

Rear Cross Path — If Equipped
The Rear Cross Path (RCP) feature is intended to aid the
drivers when backing out of parking spaces where their
vision of oncoming vehicles may be blocked. Proceed
slowly and cautiously out of the parking space until the
rear end of the vehicle is exposed. The RCP system will
then have a clear view of the cross traffic and, if an
oncoming vehicle is detected, alert the driver.
RCP monitors the rear detection zones on both sides of the
vehicle, for objects that are moving toward the side of the
vehicle with a minimum speed of approximately 3 mph(5 km/h), to objects moving a maximum of approximately
20 mph (32 km/h), such as in parking lot situations.
NOTE:
In a parking lot situation, oncoming vehicles can
be obscured by vehicles parked on either side. If the
sensors are blocked by other structures or vehicles, the
system will not be able to alert the driver.
When RCP is on and the vehicle is in REVERSE, the driver
is alerted using both the visual and audible alerts, includ-
ing reducing the radio volume so that the alert can be
better heard.
WARNING!
Rear Cross Path Detection (RCP) is not a back up aid
system. It is intended to be used to help a driver detect
an oncoming vehicle in a parking lot situation. Drivers
must be careful when backing up, even when using
RCP. Always check carefully behind your vehicle, look
behind you, and be sure to check for pedestrians,
animals, other vehicles, obstructions, and blind spots
before backing up. Failure to do so can result in serious
injury or death.

by the party responsible for compliance could void the
user ’s authority to operate the equipment.
Forward Collision Warning (FCW) Operation
The Forward Collision Warning (FCW) system provides
the driver with audible warnings, visual warnings (within
the instrument cluster display), to warn the driver when it
detects a potential frontal collision. The warnings are
intended to provide the driver with enough time to react,
avoid or mitigate the potential collision.
NOTE: FCW monitors the information from the forward
looking sensors as well as the Electronic Stability Control
(ESC) System, to calculate the probability of a forward
collision. When the system determines that a forward
collision is probable, the driver will be provided with
audible and visual warnings. When the system determines a collision with the vehicle in
front of you is no longer probable, the warning message
will be deactivated.
NOTE:
•
The minimum speed for FCW activation is 1 mph
(2 km/h).
• The FCW alerts may be triggered on objects other than
vehicles such as guard rails or sign posts based on the
course prediction. This is expected and is a part of
normal FCW activation and functionality.
FCW Message
5
SAFETY 139

•The FCW system is intended for on-road use only. If the
vehicle is taken off-road, the FCW system should be
deactivated to prevent unnecessary warnings to the
surroundings.
WARNING!
Forward Collision Warning (FCW) is not intended to
avoid a collision on its own, nor can FCW detect every
type of potential collision. The driver has the respon-
sibility to avoid a collision by controlling the vehicle
via braking and steering. Failure to follow this warn-
ing could lead to serious injury or death.
Turning FCW On Or Off
NOTE: The default status of FCW is on; this allows the
system to warn you of a possible collision with the vehicle
in front of you.
The Forward Collision activation/deactivation is located in
Uconnect Settings underSafety And Driving Assistance.
Forward Collision can be checked or unchecked.
When FCW is selected off, there will be an FCW OFFicon
that appears in the instrument cluster display. Changing the FCW status to off prevents the system from
warning you of a possible collision with the vehicle in front
of you.
NOTE:
The FCW system’s default state is on. The FCW
system state is kept in memory from one ignition cycle to
the next. If the system is turned OFF, it will remain off
when the vehicle is restarted.
Changing FCW Status
The FCW Sensitivity Settings are programmable through
the Uconnect System. Refer to “Uconnect Settings” in
“Multimedia” for further information.
The default status of FCW is the “Far” setting in the “On”
setting. This allows the system to warn you of a possible
collision with the vehicle in front of you when you are
farther away and it applies limited braking. This gives you
the most reaction time to avoid a possible collision.
Changing the FCW status to the “Near” setting, allows the
system to warn you of a possible collision with the vehicle
in front of you when you are much closer. This setting
provides less reaction time than the “Far” setting, which
allows for a more dynamic driving experience.
140 SAFETY

NOTE:
•The system will retain the last setting selected by the
driver after ignition shut down.
• FCW may not react to irrelevant objects such as over-
head objects, ground reflections, objects not in the path
of the vehicle, stationary objects that are far away,
oncoming traffic, or leading vehicles with the same or
higher rate of speed.
• FCW will be disabled like ACC, with the unavailable
screens.
Service FCW Warning
If the system turns off, and the instrument cluster display
reads:
• ACC/FCW Unavailable Service Required
• Cruise/FCW Unavailable Service Required
This indicates there is an internal system fault. Although
the vehicle is still drivable under normal conditions, have
the system checked by an authorized dealer.
General Information
The following regulatory statement applies to all Radio
Frequency (RF) devices equipped in this vehicle:
This device complies with Part 15 of the FCC Rules and
with Industry Canada license-exempt RSS standard(s).
Operation is subject to the following two conditions:
1. This device may not cause harmful interference.
2. This device must accept any interference received, in- cluding interference that may cause undesired opera-
tion.
NOTE: Changes or modifications not expressly approved
by the party responsible for compliance could void the
user ’s authority to operate the equipment.
Tire Pressure Monitoring System (TPMS)
The Tire Pressure Monitor System (TPMS) will warn the
driver of a low tire pressure based on the vehicle recom-
mended cold placard pressure.
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 de-
crease. Tire pressure should always be set based on cold
inflation tire pressure. This is defined as the tire pressure
5
SAFETY 141

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.
Refer to “Tires” in “Servicing And Maintenance” for infor-
mation on how to properly inflate the vehicle’s tires. The
tire pressure will also increase as the vehicle is driven - this
is normal and there should be no adjustment for this
increased pressure.
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 tire pressure warning
(Tire Pressure Monitoring [TPM] Telltale Light) illumi-
nates, you must increase the tire pressure to the recom-
mended cold placard pressure in order for the TPM Telltale
Light to turn off. The system will automatically update and
the TPM Telltale 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
Tire Pressure Monitoring Telltale 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 tempera-
ture drop to 20°F (-7°C) will decrease the tire pressure to
approximately 23 psi (158 kPa). This tire pressure is suffi-
ciently low enough to turn on the TPM Telltale Light.
Driving the vehicle may cause the tire pressure to rise to
approximately 27 psi (186 kPa), but the TPM Telltale Light
will still be on. In this situation, the TPM Telltale Light will
turn off only after the tires are inflated to the vehicle’s
recommended cold placard pressure value.
CAUTION!
• The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system op-
eration or sensor damage may result when using

142 SAFETY

CAUTION!(Continued)
replacement equipment that is not of the same size,
type, and/or style. The TPM sensor is not designed
for use on aftermarket wheels and may contribute to
a poor overall system performance or sensor damage.
Customers are encouraged to use OEM wheels to
assure proper TPM feature operation.
• Using aftermarket tire sealants may cause the Tire
Pressure Monitoring System (TPMS) sensor to be-
come inoperable. After using an aftermarket tire
sealant it is recommended that you take your vehicle
to your authorized dealer to have your sensor func-
tion checked.
• After inspecting or adjusting the tire pressure always
reinstall the valve stem cap. This will prevent mois-
ture and dirt from entering the valve stem, which
could damage the TPMS sensor.
NOTE:
• The TPMS is not intended to replace normal tire care and
maintenance or to provide warning of a tire failure or
condition.
• The TPMS should not be used as a tire pressure gauge
while adjusting your tire pressure. •
Driving on a significantly under-inflated tire causes the
tire to overheat and can lead to tire failure. Under-
inflation also reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and stopping
ability.
• The TPMS is not a substitute for proper tire mainte-
nance, and it is the driver ’s responsibility to maintain
correct tire pressure using an accurate tire pressure
gauge, even if under-inflation has not reached the level
to trigger illumination of the TPM Telltale Light.
• Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in the
tire.
Premium System
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.
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.

SAFETY 143

The TPMS consists of the following components:
•Receiver module
• Four tire pressure monitoring sensors
• Various tire pressure monitoring system messages,
which display in the instrument cluster
• Tire Pressure Monitoring System Warning Light
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 instrument cluster will display an “Inflate to
XX” message and a graphic showing the pressure values of
each tire with the low tire pressure values shown in a
different color.
Should this occur, you should stop as soon as possible and
inflate the tires with a low pressure condition (those shown
in a different color in the instrument cluster graphic) to the
vehicle’s recommended cold placard pressure inflation value
as shown in the “Inflate to XX” message. Once the system
receives the updated tire pressures, the system will automati-
cally update, the graphic display in the instrument cluster
will change color back to the original color, and the TPM
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.

144 SAFETY

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
Tire Pressure Monitoring Telltale Light off.
Service Tire Pressure System Warning
If a system fault is detected, the TPM 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
instrument cluster will display a Service Tire PressureSystem
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 TPM Telltale Light will no longer flash,
and the Service Tire Pressure System 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:
• 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 ma-
terials 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.

Vehicles With Compact Spare
1. The compact spare tire or non-matching full size doesnot have a tire pressure monitoring sensor. Therefore,
the TPMS will not monitor the pressure in the compact
spare tire.
2. If you install the compact or non-matching full size spare tire in place of a road tire that has a pressure below
the low-pressure warning limit, upon the next ignition
key cycle, the “TPMS Telltale Light” will remain on and
a chime will sound. In addition, the graphic in the
instrument cluster will still display a different color
pressure value and an Inflate to XXmessage.
3. After driving the vehicle for up to 20 minutes above 15 mph (24 km/h), the “TPMS Telltale Light” will flash
on and off for 75 seconds and then remain on solid. In
addition, the instrument cluster will display a “Service
Tire Pressure System” message for five seconds and then
display dashes (- -) in place of the pressure value.
4. For each subsequent ignition key cycle, a chime will sound, the “TPMS Telltale Light” will flash on and off
for 75 seconds and then remain on solid, and the
instrument cluster will display a “Service Tire Pressure System” message for five seconds and then display
dashes (- -) in place of the pressure value.
5. Once you repair or replace the original road tire and reinstall it on the vehicle in place of the compact spare or
non-matching full size, the TPMS will update automati-
cally. In addition, the “TPMS Telltale 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.
TPMS Deactivation — If Equipped
The TPMS can be deactivated if replacing all four wheel
and tire assemblies (road tires) with wheel and tire assem-
blies that do not have TPMS Sensors, such as when
installing winter wheel and tire assemblies on your vehicle.
To deactivate the TPMS, first replace all four wheel and tire
assemblies (road tires) with tires not equipped with Tire
Pressure Monitoring (TPM) Sensors. Then, drive the ve-
hicle for 20 minutes above 15 mph (24 km/h). The TPMS
will chime, the Tire Pressure Monitoring System Warning
Light will flash on and off for 75 seconds and then remain
