Anti-Lock Brake System (ABS) Warning
Light
The yellow ABS Warning Light will turn on when
the ignition is placed in the ON/RUN mode and
may stay on for as long as four seconds.
If the ABS Warning Light remains on or comes
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 ABS Warning Light is on.
If the ABS Warning Light is on, the brake system
should be serviced as soon as possible to
restore the benefits of Anti-Lock brakes. If the
ABS Warning Light does not come on when the
ignition is placed in the ON/RUN mode, have
the light repaired as soon as possible.
ELECTRONIC BRAKE CONTROL (EBC)
S
YSTEM
Your vehicle is equipped with an advanced
Electronic Brake Control (EBC) system. This
system includes Anti-Lock Brake System (ABS),
Brake Assist System (BAS), Electronic Brake
Force Distribution (EBD), Hill Start Assist (HSA), Electronic Roll Mitigation (ERM), Electronic
Stability Control (ESC), and Traction Control
System (TCS). These systems work together to
enhance both vehicle stability and control in
various driving conditions.
Your vehicle may also be equipped with Trailer
Sway Control (TSC) and Hill Descent Control
(HDC).
Brake Assist System (BAS)

The BAS is designed to optimize the vehicle’s
braking capability during emergency braking
maneuvers. The system detects an emergency
braking situation by sensing the rate and amount
of brake application and then applies optimum
pressure to the brakes. This can help reduce
braking distances. The BAS complements the
Anti-Lock Brake System (ABS). Applying the
brakes very quickly results in the best BAS
assistance. To receive the benefit of the system,
you must apply continuous braking pressure
during the stopping sequence (do not “pump” the
brakes). Do not reduce brake pedal pressure
unless braking is no longer desired. Once the
brake pedal is released, the BAS is deactivated.

Brake System Warning Light

The red Brake System Warning Light will turn on
when the ignition is placed in the ON/RUN mode
and may stay on for as long as four seconds.

If the Brake System Warning Light remains on or
comes on while driving, it indicates that the
brake system is not functioning properly and
that immediate service is required. If the Brake
System Warning Light does not come on when
the ignition is placed in the ON/RUN mode,
have the light repaired as soon as possible.
WARNING!

The Brake Assist System (BAS) cannot prevent
the natural laws of physics from acting on
the vehicle, nor can it increase the traction
afforded by prevailing road conditions.
BAS cannot prevent collisions, including those
resulting from excessive speed in turns, driving
on very slippery surfaces, or hydroplaning.
The capabilities of a BAS-equipped vehicle
must never be exploited in a reckless or
dangerous manner, which could jeopardize
the user's safety or the safety of others.

SAFETY283
When FCW status is set to “Only Warning”,
this prevents the system from providing
limited active braking, or additional brake
support if the driver is not braking adequately
in the event of a potential frontal collision.
When FCW status is set to “Warning and
Braking”, this allows the system to warn the
driver of a possible collision with the vehicle
in front using audible/visual warnings and it
applies autonomous braking.
The FCW system state is defaulted to “Full
On” from one ignition cycle to the next. If the
system is turned off, it will reset to “Full On”
when the vehicle is restarted.
FCW Braking Status And Sensitivity
The FCW sensitivity and Active Braking status
are programmable through the Uconnect
system Úpage 228.
Far
When the sensitivity of FCW is set to the
“Far” setting and the system status is
“Warning and Braking”, this allows the
system to warn the driver of a possible
more distant collision with the vehicle in
front using audible/visual warnings.
More cautious drivers that do not mind
frequent warnings may prefer this
setting.
Medium
When the sensitivity of FCW is set to the
“Medium” setting and the system status
is “Warning and Braking”, this allows the
system to warn the driver of a possible
collision with the vehicle in front using
audible/visual warnings.
Near
When the sensitivity of FCW is set to the
“Near” setting and the system status is
“Warning and Braking”, this allows the
system to warn the driver of a possible
closer collision with the vehicle in front
using audible/visual warnings.
This setting provides less reaction time
than the “Far” and “Medium” settings,
which allows for a more dynamic driving
experience.
More dynamic or aggressive drivers that
want to avoid frequent warnings may
prefer this setting.
FCW Limited Warning
If the instrument cluster displays “ACC/FCW
Limited Functionality” or “ACC/FCW Limited
Functionality Clean Front Windshield”
momentarily, there may be a condition that
limits FCW functionality. Although the vehicle is
still drivable under normal conditions, the active
braking may not be fully available. Once the
condition that limited the system performance
is no longer present, the system will return to its
full performance state. If the problem persists,
see an authorized dealer.
Service FCW Warning
If the system turns off, and the instrument
cluster displays:
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.

The TPMS consists of the following
components:
Receiver module
Four Tire Pressure Monitoring System
sensors
Various Tire Pressure Monitoring System
messages, which display in the instrument
cluster

Tire Pressure Monitoring System Warning Light

Tire Pressure Monitoring System Low
Pressure Warnings
The Tire Pressure Monitoring System
Warning Light will illuminate in the
instrument cluster when tire pressure
is low in one or more of the four active
road tires. The instrument cluster will display a
graphic showing the pressure values of each
tire with the low tire pressure values in a
different color. An "Inflate to XX" message will
also be displayed.
Example: Low Tire Pressure Display

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 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 automatically
update, the graphic display in the instrument
cluster will return to its original color, and the
Tire Pressure Monitoring System Warning 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. 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 Moni
-
toring System Warning Light off.
Service TPMS Warning
If a system fault is detected, the Tire Pressure
Monitoring System Warning Light will flash on
and off for 75 seconds and then remain on
solid. In addition, 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 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 Tire
Pressure Monitoring System Warning Light will no
longer flash, and the "SERVICE TPM SYSTEM"
message will no longer display, and a pressure

21_DPF_OM_EN_USC_t.book Page 286

SAFETY287

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.

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
