{Warning
Using AEB or IBA while
towing a trailer could cause
you to lose control of the
vehicle and crash. Turn the
system to Alert or Off when
towing a trailer.
A system unavailable message
may display if:
.The front of the vehicle or
windshield is not clean.
.Heavy rain or snow is
interfering with object
detection.
.There is a problem with the
StabiliTrak/Electronic
Stability Control (ESC)
system.
The AEB system does not
need service.
Front Pedestrian
Braking (FPB) System
If equipped, the FPB system
may help avoid or reduce the
harm caused by front-end crashes with nearby
pedestrians when driving in a
forward gear. FPB displays an
amber indicator,
~, when a
nearby pedestrian is detected
ahead. When approaching a
detected pedestrian too
quickly, FPB provides a red
flashing alert on the
windshield and rapidly beeps
or pulses the driver seat. FPB
can provide a boost to braking
or automatically brake the
vehicle. This system includes
Intelligent Brake Assist (IBA),
and the Automatic Emergency
Braking (AEB) system may also
respond to pedestrians. See
Automatic Emergency Braking
(AEB) 0300.
The FPB system can detect
and alert to pedestrians in a
forward gear at speeds
between 8 km/h (5 mph) and
80 km/h (50 mph). During
daytime driving, the system
detects pedestrians up to a
distance of approximately 40 m (131 ft). During nighttime
driving, system performance is
very limited.
{Warning
FPB does not provide an
alert or automatically brake
the vehicle, unless it detects
a pedestrian. FPB may not
detect pedestrians, including
children:
.When the pedestrian is
not directly ahead, fully
visible, or standing upright,
or when part of a group.
.Due to poor visibility,
including nighttime
conditions, fog, rain,
or snow.
.If the FPB sensor is
blocked by dirt, snow,
or ice.
.If the headlamps or
windshield are not cleaned
or in proper condition.

Warning (Continued)
Be ready to take action and
apply the brakes. For more
information, see Defensive
Driving0230. Keep the
windshield, headlamps, and
FPB sensor clean and in
good repair.
FPB can be set to Off, Alert,
or Alert and Brake through
vehicle settings. To view
available settings from the
infotainment screen, touch
Settings > Vehicle > Collision/
Detection Systems.
Detecting the Pedestrian
Ahead
FPB alerts and automatic
braking will not occur unless
the FPB system detects a pedestrian. When a pedestrian
that may enter the vehicle’s
forward path is detected, the
pedestrian ahead indicator will
display amber.
Front Pedestrian Alert
With Head-Up Display
Without Head-Up Display
When the vehicle approaches
a pedestrian ahead too rapidly,
the red FPB alert display will
flash on the windshield. Eight
rapid high-pitched beeps will
sound from the front, or both
sides of the Safety Alert Seat will pulse five times. When this
Pedestrian Alert occurs, the
brake system may prepare for
driver braking to occur more
rapidly which can cause a
brief, mild deceleration.
Continue to apply the brake
pedal as needed. Cruise
control may be disengaged
when the Front Pedestrian
Alert occurs.
Automatic Braking
If FPB detects it is about to
crash into a pedestrian
directly ahead, and the brakes
have not been applied, FPB
may automatically brake
moderately or brake hard. This
can help to avoid some very
low speed pedestrian crashes
or reduce pedestrian injury.
FPB can automatically brake
to detected pedestrians
between 8 km/h (5 mph) and
80 km/h (50 mph). Automatic
braking levels may be reduced
under certain conditions, such
as higher speeds.

and DIC message should go
off after the road tire is
replaced and the sensor
matching process is
performed successfully. See
“TPMS Sensor Matching
Process”later in this section.
.The TPMS sensor matching
process was not done or not
completed successfully after
rotating the tires. The
malfunction light and the DIC
message should go off after
successfully completing the
sensor matching process.
See "TPMS Sensor Matching
Process" later in this section.
.One or more TPMS sensors
are missing or damaged. The
malfunction light and the DIC
message should go off when
the TPMS sensors are
installed and the sensor
matching process is
performed successfully. See
your dealer for service.
.Replacement tires or wheels
do not match the original
equipment tires or wheels.
Tires and wheels other than those recommended could
prevent the TPMS from
functioning properly. See
Buying New Tires
0383.
.Operating electronic devices
or being near facilities using
radio wave frequencies
similar to the TPMS could
cause the TPMS sensors to
malfunction.
If the TPMS is not functioning
properly it cannot detect or
signal a low tire pressure
condition. See your dealer for
service if the TPMS
malfunction light and DIC
message come on and stay on.
Tire Fill Alert (If Equipped)
This feature provides visual
and audible alerts outside the
vehicle to help when inflating
an underinflated tire to the
recommended cold tire
pressure.
When the low tire pressure
warning light comes on: 1. Park the vehicle in a safe, level place. 2. Set the parking brake
firmly.
3. Place the vehicle in P (Park).
4. Add air to the tire that is underinflated. The turn
signal lamp will flash.
When the recommended
pressure is reached, the
horn sounds once and the
turn signal lamp will stop
flashing and briefly turn
solid.
Repeat these steps for all
underinflated tires that have
illuminated the low tire
pressure warning light.{Warning
Overinflating a tire could
cause the tire to rupture
and you or others could be
injured. Do not exceed the
maximum pressure listed on
the tire sidewall. See Tire
Sidewall Labeling 0367 and
Vehicle Load Limits 0242.

wheel positions. If it takes
longer, the matching process
stops and must be restarted.
The TPMS sensor matching
process is:1. Set the parking brake.
2. Place the vehicle in Service Mode. See Ignition
Positions 0247.
3. Make sure the Tire Pressure info display
option is turned on. The
info displays on the DIC
can be turned on and off
through the Options menu.
See Driver Information
Center (DIC) 0136.
4. Use the five-way DIC control on the right side of
the steering wheel to scroll
to the Tire Pressure
screen under the DIC info
page. See Driver
Information Center (DIC)
0136.
5. Press and hold the thumbwheel in the center
of the five-way DIC control. The horn sounds twice to
signal the receiver is in
relearn mode and the TIRE
LEARNING ACTIVE
message displays on the
DIC screen.
6. Start with the driver side front tire.
7. Place the relearn tool against the tire sidewall,
near the valve stem. Then
press the button to
activate the TPMS sensor.
A horn chirp confirms that
the sensor identification
code has been matched to
this tire and wheel
position.
8. Proceed to the passenger side front tire, and repeat
Step 7.
9. Proceed to the passenger side rear tire, and repeat
Step 7.
10. Proceed to the driver side rear tire, and repeat
Step 7. The horn sounds
two times to indicate the
sensor identification code has been matched to the
driver side rear tire, and
the TPMS sensor matching
process is no longer active.
The TIRE LEARNING
ACTIVE message on the
DIC display screen
goes off.
11. Turn the vehicle off.
12. Set all four tires to the recommended air pressure
level as indicated on the
Tire and Loading
Information label.
Tire Inspection
We recommend that the
tires, including the spare
tire, if the vehicle has one,
be inspected for signs of
wear or damage at least
once a month.
Replace the tire if:
.The indicators at three or
more places around the
tire can be seen.
