Press and release OFF when the system is
in stand by mode or switch the ignition off.
Note: You erase the set speed when you
switch the system off.
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. Adaptive cruise control is not a crash
warning or avoidance system.
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.
Do not use the system in poor
visibility, for example fog, heavy rain,
spray or snow.
Do not use adaptive cruise control
on winding roads, in heavy traffic or
when the road surface is slippery.
This could result in loss of vehicle control,
serious injury or death. WARNINGS
Do not use adaptive cruise control
when towing a trailer that has trailer
brakes. The auto-brake component
of the adaptive cruise control system does
not operate the trailer brakes. Using
adaptive cruise control when towing a
trailer that has trailer brakes may result in
the 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. The system adjusts your vehicle speed to
maintain the set gap between you and the
vehicle in front of you in the same lane.
The adaptive cruise controls are on the
steering wheel.
Switching Adaptive Cruise Control
On
Press and release
ON.
The indicator, current gap setting
and set speed appear in the
information display.

Setting the Adaptive Cruise Speed
1. Drive to desired speed.
2. Press and release 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 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
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.
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.
190
Flex (), enUSA, First Printing Cruise ControlE164805 E164805

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.
Setting the Gap Distance You can decrease or increase the distance
between your vehicle and the vehicle in
front by pressing the gap control.
Note:
It is your responsibility to select a gap
appropriate to the driving conditions. The selected gap appears in the
information display as shown by the bars
in the graphic. You can select four gap
settings.
Note:
The gap setting is time dependent
and therefore the distance automatically
adjusts with your vehicle speed.

Overriding the System
WARNING
If you override the system by pressing
the accelerator pedal, it does not
automatically apply the brakes to
maintain a gap from any vehicle ahead. You can override the set speed and gap by
pressing the accelerator pedal.
When you override the system,
the green indicator light
illuminates and the lead vehicle
graphic does not show in the information
display.
The system resumes operation when you
release the accelerator pedal. The vehicle
speed decreases to the set speed, or a
lower speed if following a slower vehicle.
Changing the Set Speed
• Press and release SET+ or SET-. When
you select km/h as the display
measurement in the information
display the set speed changes in
approximately 1 km/h increments.
When you select mph as the display
measurement in the information
display the set speed changes in
approximately 1 mph increments.
• Press the accelerator or brake pedal
until you reach the desired speed. Press
and release SET+ or SET-.
• Press and hold
SET+ or SET-. The set
speed changes in approximately 5 mph
(10 km/h)
increments.
The system may apply the brakes to slow
the vehicle to the new set speed. The set
speed displays continuously in the
information display when the system is
active. Resuming the Set Speed
Press and release RES. Your vehicle speed
returns to the previously set speed and gap
setting.
Note:
Only use resume if you are aware of
the set speed and intend to return to it.
Automatic Cancellation
The system does not operate below
12 mph (20 km/h)
. An audible warning
sounds and the automatic braking releases
if the vehicle drops below this speed.
Automatic cancellation can also occur if:
• The tires lose traction.
• The engine speed is too low.
• You apply the parking brake.
Note: A message is shown in the display if
the engine speed drops too low.
Hilly Condition Usage
You should select a lower gear position
when the system is active in situations
such as prolonged downhill driving on
steep grades, for example in mountainous
areas. The system needs additional engine
braking in these situations to reduce the
load on the vehicle ’s regular brake system
to prevent them from overheating.
Note: An audible warning sounds and the
system shuts down if it applies brakes for
an extended period of time. This allows the
brakes to cool down. The system functions
normally again when the brakes have cooled
down.
Switching Adaptive Cruise Control
Off
Press and release
OFF when the system is
in stand by mode or switch the ignition off.
Note: You erase the set speed when you
switch the system off.

Detection Issues
WARNING
On rare occasions, detection issues
can occur due to the road
infrastructures, for example bridges,
tunnels and safety barriers. In these cases,
the system may brake late or
unexpectedly. At all times, you are
responsible for controlling your vehicle,
supervising the system and intervening, if
required. 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 193
Flex (), enUSA, First Printing Cruise ControlE71621 E145632

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.
The following table lists possible causes and actions for this message displaying. Action
Cause
Clean the grille surface in front of the radar
or remove the object causing the obstruc-
tion.
The surface of the radar in the grille is dirty
or obstructed in some way.
Wait a short time. It may take several
minutes for the radar to detect that it is free
from obstruction.
The surface of the radar in the grille is clean
but the message remains in the display.
Do not use the system in these conditions
because it may not detect any vehicles
ahead.
Heavy rain or snow is interfering with the
radar signals.
Do not use the system in these conditions
because it may not detect any vehicles
ahead.
Swirling water, or snow or ice on the surface
of the road may interfere with the radar
signals.
Wait a short time or switch to normal cruise
control.
You are in a desert or remote area with no
other vehicles and no roadside objects.
Due to the nature of radar technology, it is
possible to get a blockage warning and not
be blocked. This can happen, for example,
when driving in sparse rural environments.
A false blocked condition self clears or
clears after a key cycle.
Switching to Normal Cruise
Control WARNING
Normal cruise control will not brake
when your vehicle is approaching
slower vehicles. Always be aware of
which mode you have selected and apply
the brakes when necessary. You can manually change from adaptive
cruise control to normal cruise control
through the information display. The cruise control indicator light
replaces the adaptive cruise
control indicator light if you
select normal cruise control. The gap
setting does not display, the system does
not automatically respond to lead vehicles.
Automatic braking remains active to
maintain set speed.

STEERING
Electric Power Steering
WARNINGS
The electric power steering system
has diagnostic checks that
continuously monitor the system. If
a fault is detected, a message displays in
the information display. Stop your vehicle
as soon as it is safe to do so. Switch the
ignition off. After at least 10 seconds,
switch the ignition on and watch the
information display for a steering system
warning message. If a steering system
warning message returns, have the system
checked by an authorized dealer. If the system detects an error, you
may not feel a difference in the
steering, however a serious condition
may exist. Obtain immediate service from
an authorized dealer, failure to do so may
result in loss of steering control. Your vehicle has an electric power steering
system. There is no fluid reservoir. No
maintenance is required.
If your vehicle loses electrical power while
you are driving, electric power steering
assistance is lost. The steering system still
operates and you can steer your vehicle
manually. Manually steering your vehicle
requires more effort.
Extreme continuous steering may increase
the effort required for you to steer your
vehicle. This increased effort prevents
overheating and permanent damage to
the steering system. You do not lose the
ability to steer your vehicle manually.
Typical steering and driving maneuvers
allow the system to cool and return to
normal operation. Steering Tips
If the steering wanders or pulls, check for:
•
Correct tire pressures.
• Uneven tire wear.
• Loose or worn suspension
components.
• Loose or worn steering components.
• Improper vehicle alignment.
Note: A high crown in the road or high
crosswinds may also make the steering
seem to wander or pull.
Adaptive Learning
The electronic power steering system
adaptive learning helps correct road
irregularities and improves overall handling
and steering feel. It communicates with
the brake system to help operate
advanced stability control and accident
avoidance systems. Additionally, whenever
the battery is disconnected or a new
battery installed, you must drive your
vehicle a short distance before the system
relearns the strategy and reactivates all
systems.
COLLISION WARNING SYSTEM
(If Equipped)
PRINCIPLE OF OPERATION WARNINGS
This system is designed to be a
supplementary driving aid. It is not
intended to replace the driver
’s
attention, and judgment, or the need to
apply the brakes. This system does NOT
activate the brakes automatically. Failure
to press the brake pedal to activate the
brakes may result in a collision.
200
Flex (), enUSA, First Printing Driving Aids

WARNINGS
The collision warning system with
brake support cannot help prevent
all collisions. Do not rely on this
system to replace driver judgment and the
need to maintain distance and speed. Note:
The system does not detect, warn or
respond to potential collisions with vehicles
to the rear or sides of the vehicle.
Note: The collision warning system is active
at speeds above approximately 5 mph
(8 km/h). This system is designed to alert the driver
of certain collision risks. A radar detects if
your vehicle is rapidly approaching another
vehicle traveling in the same direction as
yours.
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 99).
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 99).
