PRINCIPLE OF OPERATION
WARNINGS
Vehicle modifications involving
braking system, aftermarket roof
racks, suspension, steering system,
tire construction and wheel and tire size
may change the handling characteristics
of your vehicle and may adversely affect
the performance of the electronic stability
control system. In addition, installing any
stereo loudspeakers may interfere with
and adversely affect the electronic stability
control system. Install any aftermarket
stereo loudspeaker as far as possible from
the front center console, the tunnel, and
the front seats in order to minimize the risk
of interfering with the electronic stability
control sensors. Reducing the
effectiveness of the electronic stability
control system could lead to an increased
risk of loss of vehicle control, vehicle
rollover, personal injury and death. Remember that even advanced
technology cannot defy the laws of
physics. It’
s always possible to lose
control of a vehicle due to inappropriate
driver input for the conditions. Aggressive
driving on any road condition can cause
you to lose control of your vehicle
increasing the risk of personal injury or
property damage. Activation of the
electronic stability control system is an
indication that at least some of the tires
have exceeded their ability to grip the road;
this could reduce the operator ’s ability to
control the vehicle potentially resulting in
a loss of vehicle control, vehicle rollover,
personal injury and death. If your electronic
stability control system activates, SLOW
DOWN. The system automatically turns on each
time you switch the ignition on. If a driving condition activates either the
stability control or the traction control
system you may experience the following
conditions:
•
The stability and traction control light
flashes.
• Your vehicle slows down.
• Reduced engine power.
• A vibration in the brake pedal.
• The brake pedal is stiffer than usual.
• If the driving condition is severe and
your foot is not on the brake, the brake
pedal may move as the systems
applies higher brake forces.
The stability control system has several
features built into it to help you maintain
control of your vehicle:
Electronic Stability Control
The system enhances your vehicle ’s ability
to prevent skids or lateral slides by
applying brakes to one or more of the
wheels individually and, if necessary,
reducing engine power.
Roll Stability Control
The system enhances your vehicle ’s ability
to prevent rollovers by detecting your
vehicle ’s roll motion and the rate at which
it changes by applying the brakes to one
or more wheels individually.
Traction Control
The system enhances your vehicle ’s ability
to maintain traction of the wheels by
detecting and controlling wheel spin. See
Using Traction Control (page 174).

PRINCIPLE OF OPERATION
WARNINGS
To help avoid personal injury, please
read and understand the limitations
of the system as contained in this
section. Sensing is only an aid for some
(generally large and fixed) objects when
moving on a flat surface at parking speeds.
Certain objects with surfaces that absorb
ultrasonic waves, surrounding vehicle's
parking aid systems, traffic control
systems, fluorescent lamps, inclement
weather, air brakes, and external motors
and fans may also affect the function of
the sensing system; this may include
reduced performance or a false activation. To help avoid personal injury, always
use caution when in reverse (R) and
when using the sensing system.
This system is not designed to
prevent contact with small or moving
objects. The system is designed to
provide a warning to assist the driver in
detecting large stationary objects to avoid
damaging your vehicle. The system may
not detect smaller objects, particularly
those close to the ground. Certain add-on devices such as large
trailer hitches, bike or surfboard racks
and any device that may block the
normal detection zone of the system, may
create false beeps. Note:
Keep the sensors, located on the
bumper or fascia, free from snow, ice and
large accumulations of dirt. If the sensors
are covered, the system ’s accuracy can be
affected. Do not clean the sensors with
sharp objects.
Note: If your vehicle sustains damage to
the bumper or fascia, leaving it misaligned
or bent, the sensing zone may be altered
causing inaccurate measurement of
obstacles or false alarms. Note:
The sensing system cannot be turned
off when a MyKey is present. See Principle
of Operation (page 54).
Note: If you attach certain add-on devices
such as a trailer or bike rack, the rear sensing
system may detect that add-on device and
therefore provide warnings. It is suggested
that you disable the rear sensing system
when you attach an add-on device to your
vehicle to prevent these warnings.
The sensing system warns the driver of
obstacles within a certain range of your
vehicle. The system turns on automatically
whenever you switch the ignition on.
The system can be switched off through
the information display menu or from the
pop-up message that appears once you
shift the transmission into reverse (R). See
General Information
(page 97).
If a fault is present in the system, a warning
message appears in the information
display. See
Information Messages
(page 105).
REAR PARKING AID
The rear sensors are only active when the
transmission is in reverse (R). As your
vehicle moves closer to the obstacle, the
rate of the audible warning increases.
When the obstacle is less than
10 in
(25 cm) away, the warning sounds
continuously. If the system detects a
stationary or receding object farther than
10 in (25 cm)
from the corners of the
bumper, the tone sounds for only three
seconds. Once the system detects an
object approaching, the warning sounds
again.

Flex (), enUSA, First Printing Parking Aids

Coverage area of up to 6 ft (1.8 m) from
the rear bumper. There may be decreased
coverage area at the outer corners of the
bumper.
The system detects certain objects while
the transmission is in reverse (R) :
• Your vehicle is moving toward a
stationary object at a speed of
3 mph
(5 km/h) or less.
• Your vehicle is not moving, but a
moving object is approaching the rear
of your vehicle at a speed of
3 mph
(5 km/h) or less.
• Your vehicle is moving at a speed of
less than 3 mph (5 km/h) and a moving
object is approaching the rear of your
vehicle at a speed of less than
3 mph
(5 km/h). ACTIVE PARK ASSIST (If Equipped) WARNINGS
Designed to be a supplementary park
aid, this system may not work in all
conditions. This system cannot
replace the driver ’s attention and
judgment. The driver is responsible for
avoiding hazards and maintaining a safe
distance and speed, even when the system
is in use. Active Park Assist does not apply the
brakes under any circumstances.
Note:
The driver is always responsible for
controlling the vehicle, supervising the
system and intervening if required by
grabbing the steering wheel or pressing the
active park assist button (if equipped).
Note: The sensors may not detect objects
in heavy rain, snow or other conditions that
cause disruptive reflections.
Note: Keep the sensors, located on the
bumper or fascia, free from snow, ice and
large accumulations of dirt. Covered sensors
can affect the system's accuracy. Do not
clean the sensors with sharp objects.
Note: The sensors may not detect objects
with surfaces that absorb ultrasonic waves.
Active Park Assist is an electric parking aid
that uses ultrasonic sensors. The system
detects an available parallel parking space
and automatically steers your vehicle into
the space (hands-free) while you control
the accelerator, gearshift and brakes. The
system visually and audibly instructs you
to park your vehicle.

Flex (), enUSA, First Printing Parking AidsE130178

Certain vehicle conditions can also
deactivate the system, such as:
•
Traction control has activated on a
slippery or loose surface.
• There is an anti-lock brake system
activation or failure.
• Something touches the steering wheel. If a problem occurs with the system, a
warning message is displayed, followed
by a chime. Occasional system messages
may occur in normal operation. For
recurring or frequent system faults, contact
an authorized dealer to have your vehicle
serviced.
Troubleshooting the System The system does not look for a space
The traction control system may be off.
The transmission is in reverse (R); your vehicle must be moving forward to detect a
parking space. The system does not offer a particular space
The sensors may be covered (for example, snow, ice or dirt buildup). Covered sensors
can affect the system's functionality
There is not enough room in the parking space for your vehicle to safely park.
There is not enough space for the parking maneuver on the opposite side of the parking
space.
The parking space is farther than 5 ft (1.5 m) or closer than 16 in (40 cm) away.
Your vehicle is going faster than
22 mph (35 km/h).
The transmission is in reverse (R). Your vehicle must be moving forward to be able to
detect a parking space. The system does not position your vehicle where I want in the space
Your vehicle is rolling in the opposite direction of the transmission (rolling forward when
reverse [R] is selected).
An irregular curb along the parking space prevents the system from aligning your vehicle
properly.
Vehicles or objects bordering the space may not be positioned correctly.
Your vehicle was pulled too far past the parking space. The system performs best when
you drive the same distance past the parking space.

Setting the Adaptive Cruise Speed
1. Drive to desired speed.
2. Press and release SET+.
3. A green indicator light, the current gap
setting and your set speed appear in
the information display.
4. Take your foot off the accelerator pedal. 5. A vehicle graphic illuminates if there is
a vehicle detected in front of you.
Note: When adaptive cruise control is
active, the speedometer may vary slightly
from the set speed displayed in the
information display.
Following a Vehicle WARNINGS
When following a vehicle, your
vehicle does not decelerate
automatically to a stop, nor does
your vehicle always decelerate quickly
enough to avoid a crash without driver
intervention. Always apply the brakes when
necessary. Failing to do so may result in a
crash, serious injury or death. Adaptive cruise control only warns
of vehicles detected by the radar
sensor. In some cases there may be
no warning or a delayed warning. You
should always apply the brakes when
necessary. Failure to do so may result in a
crash, serious injury or death. Note:
The brakes may emit noise when
applied by the system.
When a vehicle ahead of you enters the
same lane or a slower vehicle is ahead in
the same lane, the vehicle speed adjusts
to maintain a preset gap distance.
A vehicle graphic illuminates in the
information display.
Your vehicle maintains a consistent gap
from the vehicle ahead until:
• The vehicle in front of you accelerates
to a speed above the set speed.
• The vehicle in front of you moves out
of the lane you are in.
• Your vehicle speed falls below
12 mph
(20 km/h).
• You set a new gap distance.
The system applies the brakes to slow your
vehicle to maintain a safe gap distance
from the vehicle in front. The brake lamps
automatically turn on when the system
applies the brakes. The maximum braking
which the system applies is limited. You
can override the system by applying the
brakes.
If the system determines that its maximum
braking level will not be sufficient, an
audible warning sounds when the system
continues to brake. A red warning bar
displays on the windshield and you must
take immediate action.
Note: When you are following a vehicle and
you switch on a direction indicator, adaptive
cruise control may provide a small
temporary acceleration to help you pass.

The radar sensor has a limited field of
vision. It may not detect vehicles at all or
detect a vehicle later than expected in
some situations. The lead vehicle graphic
does not illuminate if the system does not
detect a vehicle in front of you.
Detection issues can occur:
With vehicles that edge into your
lane that can only be detected
once they have moved fully into
your lane.
A
Motorcyclists may be detected
late, or not at all.
B
With vehicles in front of you
when going into and coming out
of a bend. The detection beam
does not follow sharp curves in
the road.
C In these cases the system may brake late
or unexpectedly. You should stay alert and
intervene if necessary.
If something hits the front of your vehicle
or damage occurs, the radar-sensing zone
may change. This could cause missed or
false vehicle detections. Contact an
authorized dealer as soon as possible.
System Not Available
Conditions that can cause the system to
deactivate or prevent the system from
activating when requested include:
•
A blocked sensor.
• High brake temperature.
• A failure in the system or a related
system.
Blocked Sensor A message displays if something obstructs
the radar signals from the sensor. The
sensor is located on the lower grille. The
system cannot detect a vehicle ahead and
does not function when something
obstructs the radar signals.

If it is, a red warning light illuminates and
an audible warning chime sounds.
The brake support system assists the driver
in reducing the collision speed by charging
the brakes. If the risk of collision further
increases after the warning light
illuminates, the brake support prepares
the brake system for rapid braking. This
may be apparent to the driver. The system
does not automatically activate the brakes
but, if the brake pedal is pressed, full force
braking is applied even if the brake pedal
is lightly pressed.
Using the Collision Warning System
WARNING
The collision warning system
’s brake
support can only help reduce the
speed at which a collision occurs if
the driver applies the vehicle ’s brakes. The
brake pedal must be pressed just like any
typical braking situation. The warning system sensitivity can be
adjusted to one of three possible settings
by using the information display control.
See General Information (page 97).
Note: If collision warnings are perceived as
being too frequent or disturbing then the
warning sensitivity can be reduced, though
the manufacturer recommends using the
highest sensitivity setting where possible.
Setting lower sensitivity would lead to fewer
and later system warnings. See
General
Information (page 97).
Blocked Sensors If a message regarding a blocked sensor
appears in the information display, the
radar signals from the sensor have been
obstructed. The sensors are located behind
a fascia cover near the driver side of the
lower grille. When the sensors are
obstructed, a vehicle ahead cannot be
detected and the collision warning system
does not function. The following table lists
possible causes and actions for this
message being displayed.
