FORWARD COLLISION WARNING (FCW) WITH
MITIGATION — IF EQUIPPED
Forward Collision Warning (FCW) With Mitigation
Operation
The Forward Collision Warning (FCW) system with
mitigation provides the driver with audible warnings,
visual warnings (within the DID), and may apply a brake
jerk to warn the driver when it detects a potential frontal
collision. The warnings and limited braking are intended
to provide the driver with enough time to react, avoid or
mitigate the potential collision.
214 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

NOTE:FCW monitors the information from the forward
looking sensors as well as the Electronic Brake Controller
(EBC), 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 and may provide a brake jerk warning. If
the driver does not take action based upon these progres-
sive warnings, then the system will provide a limited
level of active braking to help slow the vehicle and
mitigate the potential forward collision. If the driver
reacts to the warnings by braking and the system deter-
mines that the driver intends to avoid the collision by
braking but has not applied sufficient brake force, the
system will compensate and provide additional brake
force as required.When the system determines a collision with the vehicle
in front of you is no longer probable, the warning
message will be deactivated.

To turn the FCW system back ON, push the forward
collision button again to turn the system ON (led turns
off).
Changing the FCW status to “Off” prevents the system
from warning you of a possible collision with the vehicle
in front of you.
Changing the Active Braking status to “Off” prevents the
system from providing limited autonomous braking, or
additional brake support if the driver is not braking
adequately in the event of a potential frontal collision.
NOTE: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 And Active Braking Status
The FCW Sensitivity And Active Braking Settings are
programmable through the Uconnect® System. Refer to
“Uconnect® Settings” in “Understanding Your Instru-
ment Panel” for further information.
The default status of FCW is the “Far” setting and the
Active Braking is 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.

INSTRUMENT CLUSTER DESCRIPTIONS
1. Tachometer
Indicates the engine speed in revolutions per minute
(RPM x 1000).
2. Seat Belt Reminder Light
When the ignition switch is first turned to the
ON/RUN position, this light will turn on for four
to eight seconds as a bulb check. During the bulb
check, if the driver’s seat belt is unbuckled, a chime will
sound. After the bulb check or when driving, if the driver
or front passenger seat belt remains unbuckled, the Seat
Belt Indicator Light will flash or remain on continuously.
Refer to “Occupant Restraints” in “Things To Know
Before Starting Your Vehicle” for further information.3. Anti-Lock Brake (ABS) Light
This light monitors the Anti-Lock Brake System
(ABS). The light will turn on when the ignition
switch is turned to the ON/RUN position and
may stay on for as long as four seconds.
If the ABS light remains on or turns 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 BRAKE warning light is not on.
If the ABS light is on, the brake system should be serviced
as soon as possible to restore the benefits of Anti-Lock
brakes. If the ABS light does not turn on when the
ignition switch is turned to the ON/RUN position, have
the light inspected by an authorized dealer.
4. High Beam Indicator
Indicates that headlights are on high beam.

CAUTION!
Driving with a hot engine cooling system could
damage your vehicle. If the temperature gauge reads
“H” pull over and stop the vehicle. Idle the vehicle
with the air conditioner turned off until the pointer
drops back into the normal range. If the pointer
remains on the “H” and you hear continuous chimes,
turn the engine off immediately and call an autho-
rized dealer for service.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer
for service if your vehicle overheats. If you decide to
look under the hood yourself, see “Maintaining Your
(Continued)
WARNING!(Continued)
Vehicle”. Follow the warnings under the Cooling
System Pressure Cap paragraph.
12. Brake Warning Light
This light monitors various brake functions,
including brake fluid level and parking brake
application. If the brake light turns on it may
indicate that the parking brake is applied, that
the brake fluid level is low, or that there is a problem with
the anti-lock brake system reservoir.
If the light remains on when the parking brake has been
disengaged, and the fluid level is at the full mark on the
master cylinder reservoir, it indicates a possible brake
hydraulic system malfunction or that a problem with the
Brake Booster has been detected by the Anti-Lock Brake
System (ABS) / Electronic Stability Control (ESC) system.
In this case, the light will remain on until the condition
4
UNDERSTANDING YOUR INSTRUMENT PANEL 289

has been corrected. If the problem is related to the brake
booster, the ABS pump will run when applying the brake
and a brake pedal pulsation may be felt during each stop.
The dual brake system provides a reserve braking capac-
ity in the event of a failure to a portion of the hydraulic
system. A leak in either half of the dual brake system is
indicated by the Brake Warning Light, which will turn on
when the brake fluid level in the master cylinder has
dropped below a specified level.
The light will remain on until the cause is corrected.
NOTE:The light may flash momentarily during sharp
cornering maneuvers, which change fluid level condi-
tions. The vehicle should have service performed, and
the brake fluid level checked.
If brake failure is indicated, immediate repair is neces-
sary.WARNING!
Driving a vehicle with the red brake light on is
dangerous. Part of the brake system may have failed.
It will take longer to stop the vehicle. You could have
a collision. Have the vehicle checked immediately.
Vehicles equipped with the Anti-Lock Brake System
(ABS), are also equipped with Electronic Brake Force
Distribution (EBD). In the event of an EBD failure, the
Brake Warning Light will turn on along with the ABS
Light. Immediate repair to the ABS system is required.
Operation of the Brake Warning Light can be checked by
turning the ignition switch from the OFF position to the
ON/RUN position. The light should illuminate for ap-
proximately two seconds. The light should then turn off
unless the parking brake is applied or a brake fault is
detected. If the light does not illuminate, have the light
inspected by an authorized dealer.
290 UNDERSTANDING YOUR INSTRUMENT PANEL

The light also will turn on when the parking brake is
applied with the ignition switch in the ON/RUN posi-
tion.
NOTE:This light shows only that the parking brake is
applied. It does not show the degree of brake application.
13. Fuel Gauge/Fuel Door Reminder
The fuel pump symbol points to the side of the vehicle
where the fuel door is located. The pointer shows the
level of fuel in the fuel tank when the ignition switch is in
the ON/RUN position.
14. Tire Pressure Monitoring Telltale Light
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your vehicle
has tires of a different size than the size indicated on thevehicle placard or tire inflation pressure label, you should
determine the proper tire inflation pressure for those
tires.)
As an added safety feature, your vehicle has been
equipped with a Tire Pressure Monitoring System
(TPMS) that illuminates a low tire pressure telltale when
one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure telltale illumi-
nates, you should stop and check your tires as soon as
possible, and inflate them to the proper 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.
Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver ’s responsibility to
maintain correct tire pressure, even if under-inflation has
not reached the level to trigger illumination of the TPMS
low tire pressure telltale.

The main display area will normally display the main
menu or the screens of a selected feature of the main
menu. The main display area also displays “pop up”
messages that consist of approximately 60 possible warn-
ing or information messages. These pop up messages fall
into several categories:
•Five Second Stored Messages
When the appropriate conditions occur, this type of
message takes control of the main display area for five
seconds and then returns to the previous screen. Most of
the messages of this type are then stored (as long as the
condition that activated it remains active) and can bereviewed from the “Messages” main menu item. Ex-
amples of this message type are “Right Front Turn Signal
Lamp Out” and “Low Tire Pressure.”
•Unstored Messages
This message type is displayed indefinitely or until the
condition that activated the message is cleared. Examples
of this message type are “Turn Signal On” (if a turn signal
is left on) and “Lights On” (if driver leaves the vehicle).
•Unstored Messages Until RUN
These messages deal primarily with the Remote Start
feature. This message type is displayed until the ignition
is in the RUN state. Examples of this message type are
“Remote Start Aborted - Door Ajar” and “Press Brake
Pedal and Push Button to Start.”
•Five Second Unstored Messages
When the appropriate conditions occur, this type of
message takes control of the main display area for five
298 UNDERSTANDING YOUR INSTRUMENT PANEL

seconds and then returns to the previous screen. An
example of this message type is “Automatic High Beams
On.”
Engine Oil Life Reset
Oil Change Required
Your vehicle is equipped with an engine oil change
indicator system. The “Oil Change Required” message
will display in the DID for five seconds after a single
chime has sounded, to indicate the next scheduled oil
change interval. The engine oil change indicator system
is duty cycle based, which means the engine oil change
interval may fluctuate, dependent upon your personal
driving style.
Unless reset, this message will continue to display each
time you cycle the ignition to the ON/RUN position. To
turn off the message temporarily, push and release theOK button. To reset the oil change indicator system (after
performing the scheduled maintenance), refer to the
following procedure.
Oil Change Reset Procedure
1. Without pushing the brake pedal, push and release the
ENGINE START/STOP button and place the ignition
to the ON/RUN position (do not start the engine).
2. Fully push the accelerator pedal, slowly, three times
within 10 seconds.
3. Without pushing the brake pedal, push and release the
ENGINE START/STOP button once to return the
ignition to the OFF/LOCK position.
NOTE:If the indicator message illuminates when you
start the vehicle, the oil change indicator system did not
reset. If necessary, repeat this procedure.4
