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 fault occurs in either the stability
control or the traction control system, you
may experience the following conditions:
•
The stability and traction control light
illuminates steadily.
• The stability control and traction
control systems do not enhance your
vehicle's ability to maintain traction of
the wheels.
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 system applies
higher brake force.
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.

PRINCIPLE OF OPERATION
WARNINGS
To help avoid personal injury, always
use caution when in reverse (R) and
when using the sensing system.
The system may not detect objects
with surfaces that absorb reflection.
Always drive with due care and
attention. Failure to take care may result
in a crash. Traffic control systems, inclement
weather, air brakes, external motors
and fans may affect the correct
operation of the sensing system.This may
cause reduced performance or false alerts. The system may not detect small or
moving objects, particularly those
close to the ground.
Note:
If your vehicle is equipped with
MyKey ™, the sensing system cannot be
turned off when a MyKey ™ is present. See
Principle of Operation (page 57).
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 alerts.
Note: Certain add-on devices installed
around the bumper or fascia may create
false alerts. For example, large trailer
hitches, bike or surfboard racks, license plate
brackets, bumper covers or any other device
that may block the normal detection zone
of the system. Remove the add-on device
to prevent false alerts. Note:
When a trailer is connected to your
vehicle, the rear parking aid may detect the
trailer and therefore provide an alert. Disable
the rear parking aid when a trailer is
connected to prevent the alert.
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
12 in
(30 cm) away, the warning sounds
continuously. If the system detects a
stationary or receding object farther than
12 in (30 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.
180
Flex (TP3) , enUSA, Edition date: 201801, Second 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
You must remain in your vehicle
when the system turns on. At all
times, you are responsible for
controlling your vehicle, supervising the
system and intervening, if required. Failure
to take care may result in the loss of
control of your vehicle, serious personal
injury or death. The system is designed to aid the
driver. It is not intended to replace
your attention and judgment. You are
still responsible to drive with due care and
attention. The sensors may not detect objects
in heavy rain or other conditions that
cause interference.
Active park assist does not apply the
brakes under any circumstances.
Note:
The blind spot information system
does not detect traffic alongside or behind
your vehicle during an active park assist
maneuver.
Note: Active park assist is a multi-step
process and may require you to shift your
transmission multiple times. Follow the
on-screen instructions until you complete
the parking process.
The system detects an available parallel
parking space and automatically steers
your vehicle (hands-free) while you control
the accelerator, transmission and brakes.
The system visually and audibly guides you
to park your vehicle.
If you are uncomfortable with the proximity
to any vehicle or object, you may choose
to override the system by grabbing the
steering wheel or pushing the active park
assist button.

Flex (TP3) , enUSA, Edition date: 201801, Second Printing Parking AidsE130178

The system may not operate correctly in
any of the following conditions:
•
You use a spare tire or a tire
significantly worn more than the other
tires.
• One or more tires are improperly
inflated.
• You try to park on a tight curve.
• Something passes between the front
bumper and the parking space. For
example, a pedestrian or cyclist.
• The edge of the neighboring parking
vehicle is high off the ground. For
example, a bus, tow truck or flatbed
truck.
• The weather conditions are poor. For
example, during heavy rain, snow or
fog.
Note: Keep the sensors, located on the
fascia, free from now, ice and large
accumulations of dirt. Covered sensors can
affect the systems accuracy. Do not clean
the sensors with sharp objects.
Note: The sensors may not detect objects
with surfaces that absorb ultrasonic waves
or cause ultrasonic interference. For
example, motorcycle exhaust, truck air
brakes or horns. Note:
Following a change in tire size, the
system must recalibrate and operation may
be impaired for a short time.
Do not use the system if:
• You have attached a bike rack, trailer
or other object near the sensors on the
front or rear of your vehicle.
• You have attached an overhanging
object to the roof. For example, a
surfboard.
• A foreign object damages or obstructs
the sensors.
• The correct tire size is not in use. For
example, when using a mini-spare tire.
Using Active Park Assist Press the button to turn the
system on or off.
When driving at a speed less than 22 mph
(35 km/h), the system automatically scans
both sides of your vehicle for an available
parking space. The system displays a
message and a corresponding graphic to
indicate it is searching for a parking space.
Use the direction indicator to select
searching either to the left hand side or
right hand side of your vehicle. If the
direction indicator is not used, the system
defaults to the passenger side of your
vehicle. 182

USING ADAPTIVE CRUISE
CONTROL (If Equipped)
WARNINGS
Always pay close attention to
changing road conditions when using
adaptive cruise control. The system
does not replace attentive driving. Failing
to pay attention to the road may result in
a crash, serious injury or death. Do not use the adaptive cruise
control when entering or leaving a
highway, on roads with intersections
or roundabouts or non-vehicular traffic or
roads that are winding, slippery, unpaved,
or steep slopes. Do not use the system in poor
visibility, for example fog, heavy rain,
spray or snow.
Do not use the system when towing
a trailer with aftermarket trailer
brake controls. Aftermarket trailer
brakes will not function properly when you
switch the system on because the brakes
are electronically controlled. Failing to do
so may result in loss of vehicle control,
which could result in serious injury. Do not use tire sizes other than those
recommended because this can
affect the normal operation of the
system. Failure to do so may result in a loss
of vehicle control, which could result in
serious injury. Adaptive cruise control may not
detect stationary or slow moving
vehicles below
6 mph (10 km/h).
Adaptive cruise control does not
detect pedestrians or objects in the
road.
Adaptive cruise control does not
detect oncoming vehicles in the
same lane. WARNINGS
Adaptive cruise control is not a crash
warning or avoidance system.
Note:
It is your responsibility to stay alert,
drive safely and be in control of the vehicle
at all times.
The system adjusts your vehicle speed to
maintain the set gap between you and the
vehicle in front of you in the same lane.
You can select four gap settings.
The system uses a radar sensor that
projects a beam directly in front of your
vehicle. The adaptive cruise controls are on the
steering wheel.
Switching Adaptive Cruise Control
On
Press
ON.
The indicator, current gap setting
and set speed appear in the
information display.

Flex (TP3) , enUSA, Edition date: 201801, Second Printing Cruise ControlE173611 E144529

Setting the Adaptive Cruise Speed
Note:
When adaptive cruise control is
active, the speedometer may vary slightly
from the set speed displayed in the
information display.
1. Drive to desired speed.
2. Press SET+ or 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 image illuminates if the
system detects a vehicle in front of you. 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:
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.
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
instrument cluster.
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.
