GETTING TO KNOW YOUR INSTRUMENT PANEL59
WARNING LIGHTS AND MESSAGES

The warning/indicator lights will illuminate in the
instrument panel together with a dedicated message
and/or acoustic signal when applicable. These
indications are indicative and precautionary and as
such must not be considered as exhaustive and/or
alternative to the information contained in the Owner’s
Manual, which you are advised to read carefully in all
cases. Always refer to the information in this chapter in
the event of a failure indication. All active telltales will
display first if applicable. The system check menu may
appear different based upon equipment options and
current vehicle status. Some telltales are optional and
may not appear.

RED WARNING LIGHTS
Air Bag Warning Light

This light will turn on for four to eight seconds
as a bulb check when the ignition is placed in
the ON/RUN or MAR/ON/RUN position. If the
light is either not on during startup, stays on,
or turns on while driving, have the system inspected at
an authorized dealer as soon as possible. This light will
illuminate with a single chime when a fault with the
Air Bag Warning Light has been detected, it will stay
on until the fault is cleared. If the light comes on
intermittently or remains on while driving, have an
authorized dealer service the vehicle immediately.

Brake Warning Light
This warning 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 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
capacity 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
conditions. The vehicle should have service
performed, and the brake fluid level checked.
If brake failure is indicated, immediate repair is
necessary.
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 approximately 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.
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.

15 seconds when the vehicle security system is
arming, and then will flash slowly until the vehicle
is disarmed.
Oil Pressure Warning Light
This warning light will illuminate to
indicate low engine oil pressure. If the
light turns on while driving, stop the
vehicle, shut off the engine as soon
as possible, and contact an authorized dealer.
A chime will sound when this light turns on.
Do not operate the vehicle until the cause is
corrected. This light does not indicate how much oil
is in the engine. The engine oil level must be
checked under the hood.
Seat Belt Reminder Warning Light
When the ignition is first placed in the
ON/RUN or MAR/ON/RUN position, if the
driver’s seat belt is unbuckled, a chime
will sound and the light will turn on. When
driving, if the driver or front passenger seat belt
remains unbuckled, the Seat Belt Reminder Light
will flash or remain on continuously and a chime
will sound Ú page 154.

Anti-Lock Brake System (ABS) Warning
Light
This light monitors the ABS. The light will
turn on when the ignition is placed in the
ON/RUN or MAR/ON/RUN position and
may stay on for as long as four seconds.
If the ABS light remains on or turns on while
driving, then the Anti-Lock portion of the brake
system is not functioning and 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 is placed in the
ON/RUN or MAR/ON/RUN position, have the light
inspected by an authorized dealer.

a vehicle in front is detected Ú page 82.

22_VF_OM_EN_USC_t.book Page 66

STARTING AND OPERATING87

Distance Settings

To adjust the distance setting, push the Distance
Setting Button and release. Each time the button is
pushed, the distance setting decreases by one bar
(longer). Once the longest setting is reached, if the
button is pushed again it will be set to the shortest
setting available.
If a slower moving vehicle is detected in the same
lane, the instrument cluster display will show the
ACC Set With Target Detected Light. The system
will then adjust vehicle speed automatically to
maintain the distance setting, regardless of the
set speed.
The vehicle will then maintain the set distance until:

The vehicle ahead accelerates to a speed above
the set speed.
The vehicle ahead moves out of your lane or
view of the sensor.
The distance setting is changed.
The system disengages Ú
page 84.
The maximum braking applied by ACC is limited;
however, the driver can always apply the brakes
manually, if necessary.
NOTE:The brake lights will illuminate whenever the ACC
system applies the brakes.
A Proximity Warning will alert the driver if ACC
predicts that its maximum braking level is not
sufficient to maintain the set distance. If this
occurs, a visual alert “BRAKE!” will flash in the
instrument cluster display and a chime will sound
while ACC continues to apply its maximum braking
force.
NOTE:The “BRAKE!” screen in the instrument cluster
display is a warning for the driver to take action
and does not necessarily mean that the Forward
Collision Warning system is applying the brakes
autonomously.
Overtake Aid
When driving with Adaptive Cruise Control (ACC)
engaged and following a vehicle, the system will
provide an additional acceleration up to the ACC
set speed to assist in passing the vehicle. This
additional acceleration is triggered when the driver
utilizes the left turn signal and will only be active
when passing on the left hand side.
ACC Operation At Stop
In the event that the ACC system brings your
vehicle to a standstill while following a vehicle in
front, if the vehicle in front starts moving within two
seconds of your vehicle coming to a standstill, your
vehicle will resume motion without the need for
any driver action.
If the vehicle in front does not start moving within
two seconds of your vehicle coming to a standstill,
the driver will either have to push the RES (resume)
button, or apply the accelerator pedal to reengage
the ACC to the existing set speed.
NOTE:After the ACC system holds your vehicle at a stand -
still for approximately three consecutive minutes,
the parking brake will be activated, and the ACC
system will be cancelled.
While ACC is holding your vehicle at a standstill, if
the driver seat belt is unbuckled or the driver door
is opened, the parking brake will be activated, and
the ACC system will be cancelled.

The following conditions must be met before the
system will engage:
Active Driving Assist system is enabled
ACC is engaged
System detects visible lane markings
Vehicle is traveling below 93 mph (150 km/h)
Vehicle is centered in lane
Turn signal is not activated
Vehicle is not in a tight curve
Driver has hands on steering wheel
NOTE:For the system to detect the driver’s hands on the
steering wheel, the wheel must be gripped on the
outside. Gripping the inside areas of the steering
wheel will not satisfy the hands-on condition to
engage the system.
Do Not Grip Inside Of Steering Wheel

System Deactivation
The system will be deactivated in any of the
following situations:
If the system has detected driver inattentive -
ness, and has gone through all escalation warn -
ings after hands are no longer detected on the
steering wheel
If lane markings are no longer detected
If the Active Driving Assist on/off button is
pushed again (ADA will turn off)
If a turn signal is used
If the driver applies torque to the steering wheel

If the vehicle speed exceeds 93 mph (150 km/h)

If the ACC system is deactivated

If the Forward Collision Warning (FCW) system
becomes active and is providing warnings/braking

NOTE:
Pushing the Active Driving Assist on/off button
will turn the system off. All other deactivation
conditions will place the system back into the
“enabled” state with the steering wheel indi -
cator displayed in grey until all engagement
conditions are met again.
When the system is deactivated, the system
status indicator lights will turn off, Active Lane
Management will return to its previous state,
and ACC will disable.
INDICATIONS ON THE DISPLAY
The Active Driving Assist system status can always
be viewed in the instrument cluster display, and
status changes are shown by changes in color of
the system’s indicator lights.
As the system detects driver inattentiveness as
previously described Ú page 92, the system
status indicator lights will change from green, to
yellow, to red, while the steering wheel icon on
the display moves up the screen to the center.
The following indicators will change in color as
warnings to the driver escalate:
Active Driving Assist Indicator (steering wheel
icon in the instrument cluster display)
Glow effect of the instrument cluster display

22_VF_OM_EN_USC_t.book Page 94

STARTING AND OPERATING95
If driver attention is not returned, the system will
deactivate.
Active Driving Assist Indicators Are Off
ADA is not turned on/enabled by the driver.
Active Driving Assist Indicators Are Grey
ADA is turned on/enabled by the driver, but the
system is not actively providing steering to the
vehicle.

Driver inattentiveness is still being detected,
warning the driver to place hands on the
steering wheel.
NOTE:The driver MUST replace hands on the steering
wheel and take control of the vehicle when the
system is deactivated.
Active Driving Assist Cancelled Message

MINIMUM RISK MANEUVER
If the driver removes the hands from the steering
wheel, a counter will start in order to display and
activate visual and acoustic alerts. When the
hands absence is detected the system will start
Minimum Risk Maneuver for bringing the vehicle in
a safe position.
After 23 seconds from the absence of the hands
on the steering wheel, the Adaptive System Cruise
Control will apply a brake jerk to warn the driver to
take vehicle control. If, after another 3 seconds the
driver does not take the control of the vehicle, the
system will apply a second brake jerk.Subsequently, if the absence of hands on the
steering wheel persists, the system will apply an
automatic braking intervention to bring the vehicle
to the stop. As soon as the standstill condition is
reached, the hazard emergency lights will be
activated. Then, the system will unlock the doors
(if previously locked). If the driver will take the
control of the vehicle during the Minimum Risk
Maneuver by placing the hands on the steering
wheel or pressing the pedal throttle, the system
will behave normally and the Minimum Risk
Maneuver will be stopped.
SYSTEM STATUS

Along with changes in the system’s indicator lights
(green, yellow, and red), the system can also issue a
steering wheel vibration to accompany these warnings.
The vibration warning (if enabled) will occur if the
vehicle crosses a lane marker, for example, when
driving on a tight curve. This feature can be turned on
or off within the Uconnect system

96STARTING AND OPERATING
SYSTEM OPERATION/LIMITATIONS
The Active Driving Assist system DOES NOT:
Warn or prevent collisions with other vehicles
Steer your vehicle around stopped vehicles,
slower vehicles, construction equipment,
pedestrians, or animals
Respond to traffic lights or stop signs
Merge onto highways or exit off ramps
Turn your vehicle
Change lanes
React to cross traffic The Active Driving Assist system may have limited
or reduced functionality when one of the following
conditions occur:
The vehicle’s radar sensors and/or forward
facing camera is damaged, covered, or
obstructed (e.g. by mud, ice, snow, etc.)
Driving near highway toll booths
NOTE:If damage to the windshield occurs, have the wind
-
shield replaced by an authorized dealer as soon as
possible.
PARKSENSE FRONT/REAR PARK ASSIST —
IF EQUIPPED
The ParkSense Park Assist system provides visual
and audible indications of the distance between
the rear, and if equipped, the front fascia/bumper
and a detected obstacle when backing up or
moving forward (e.g. during a parking maneuver).
For limitations of the system (e.g. during a parking
maneuver), see Ú page 101.
NOTE:
The system is designed to assist the driver and
not to substitute the driver.

The driver must stay in full control of the vehicle's
acceleration and braking and is responsible for
controlling the vehicle's movements.
ParkSense will retain the last system state
(enabled or disabled) from the last ignition cycle
when the ignition is placed in the ON/RUN position.
ParkSense is active when the gear selector is
shifted to REVERSE or to a forward gear and an
obstacle is detected, as long as the system is on.
When the gear selector shifted to NEUTRAL or
PARK, the system becomes inactive. When the
vehicle is moving forward, the system will remain
active until the vehicle speed remains below
approximately 11 mph (18 km/h). Reducing the
speed approximately below 9 mph (15 km/h), the
system will come back active. When the vehicle is
moving in REVERSE, the system will remain active
as long as the speed remains below the maximum
operating speed of 7 mph (11 km/h). When the
maximum speed limit is exceeded, the system is
disabled and the ParkSense switch LED with
illuminate. The system will become active again if
the vehicle speed reduces below approximately
6 mph (9 km/h).
WARNING!
To prevent serious injury or death:
Always remain alert and be ready to take
control of the vehicle in the event that the
Active Driving Assist system disables.

Always keep your hands on the steering wheel
when the Active Driving Assist system is activated.

Maintain a safe distance from other vehicles
and pay attention to traffic conditions.
Do not place any objects on the steering wheel
(e.g. steering wheel covers) which could inter
-
fere with the hand detection sensors.
