• Driving on a slope The performance of Forward Collision-
Avoidance Assist system may be
decreased while driving upward or
downward on a slope.
The front view camera or front radar
sensor recognition may not detect the
vehicle, pedestrian or cyclist in front.
This may result in unnecessary alarm
and braking or no alarm and braking
when necessary.
When the system suddenly recognizes
the vehicle, pedestrian or cyclist in
front while passing over a slope, you
may experience sharp deceleration.
Always keep your eyes forward while
driving upward or downward on a
slope, and, if necessary, depress the
brake pedal to reduce your driving
speed in order to maintain distance.

• Changing lanesWhen a vehicle changes lanes in
front of you, FCA system may not
immediately detect the vehicle,
especially if the vehicle changes
lanes abruptly. In this case, you must
maintain a safe braking distance, and
if necessary, depress the brake pedal
to reduce your driving speed in order
to maintain a safe distance.

When driving in stop-and-go traffic,
and a vehicle in front of you merges
out of the lane, FCA system may not
immediately detect the new vehicle
that is now in front of you. In this case,
you must maintain a safe braking
distance, and if necessary, depress
the brake pedal to reduce your driving
speed in order to maintain a safe
distance.

• Detecting the vehicle in front of youIf the vehicle in front of you has cargo
that extends rearward from the cab,
or when the vehicle in front of you has
higher ground clearance, additional
special attention is required. FCA
system may not be able to detect the
cargo extending from the vehicle. In
these instances, you must maintain
a safe braking distance from the
rearmost object, and if necessary,
depress the brake pedal to reduce
your driving speed in order to
maintain distance.

FCA warning message and function
control
FCA produces warning messages and
warning alarms as well as vibrates the
steering wheel in accordance with the
collision risk levels whilst the vehicle
turns left at the crossroads. In addition,
the system controls the brakes according
to the collision risk levels.

Collision warning (First warning)
-
The warning message appears on the LCD display with a warning chime and
the steering wheel vibrates.

- The vehicle may slow down slightly.
- The system works when the vehicle speed is under 19 mph (30 km/h).
(The operable speed range might be
reduced according to the condition
and surroundings of the approaching
vehicles.)
- If you select “Warning only” on the LCD display or infotainment system,
the system does not control the

Emergency braking (Second warning) -
The warning message appears on the LCD display with a warning chime and
the steering wheel vibrates.

- FCA system limitedly controls the
brakes to preemptively mitigate
impact in collision. The brake control
is maximised just before a collision.
- The system works when the vehicle speed is under 19 mph (30 km/h).
(The operable speed range might be
reduced according to the condition
and surroundings of the approaching
vehicles.)
- If you select “Warning only” on the LCD display or infotainment system,
the system does not control the
brake so you should control the brake
directly.
WARNING
FCA-Junction Turning function
only activates for vehicles except
pedestrians, two wheel vehicles,
animals or obstacles.
WARNING
FCA braking control cannot completely
stop the vehicle nor avoid all
collisions. The driver should hold the
responsibility to safely drive and control
the vehicle.
WARNING
FCA-Junction Turning function operates
in accordance with the collision risk
levels based on certain parameters
such as the condition, driving direction
and speed of the approaching vehicle.
Never deliberately drive dangerously to
activate the system.

WARNING
• The warning light on the side view
mirror will illuminate whenever a
vehicle is detected at the rear side by
the system.
To avoid accidents, do not focus only
on the warning light and neglect to
see the surrounding of the vehicle.
• Drive safely even though the
vehicle is equipped with Blind-Spot
Collision-Avoidance Assist system.
Do not solely rely on the system
but check your surrounding before
changing lanes or backing the
vehicle up.
• The system may not alert the driver
in some conditions so always check
your surroundings while driving.
CAUTION
• The driver should always use
extreme caution while operating
the vehicle, whether or not the
warning light on the side view mirror
illuminates or there is a warning
alarm.
• Playing the vehicle audio system at
high volume may offset the Blind-
Spot Collision Warning system
warning sounds.
• The warning of Blind-Spot Collision-
Avoidance Assist system may not
sound while other system’s warning
sounds.
Blind-Spot Collision-Avoidance
Assist
Blind-Spot Collision-Avoidance Assist
system may apply braking power, when
an approaching vehicle is detected
within a certain distance next to or
behind your vehicle.
It gently applies braking power on the
tire, which is located in the opposite
side of the possibly-colliding point. The
instrument cluster will inform the driver
of the system activation.
Blind-Spot Collision-Avoidance Assist
system is automatically deactivated
when:
- The vehicle drives a certain distance away
- The vehicle direction is changed against the possible-colliding point
- The steering wheel is abruptly moved
- The brake pedal is depressed
- After a certain period of time
The driver should drive the vehicle in the
middle of the vehicle lanes to keep the
system in the ready status.
When the vehicle drives too close to one
side of the vehicle lanes, the system may
not properly operate.
In addition, the system may not properly
control your vehicle in accordance with
driving situations. Thus, always pay close
attention to road situations.
