Driving your vehicle
Limitations of the System
The Automatic Emergency Braking
(AEB) system is designed to monitor the
vehicle ahead or a pedestrian in the
roadway through radar signals and cam-
era recognition to warn the driver that a
collision is imminent, and if necessary,
apply emergency braking.
In certain situations, the radar sensor or
the camera may not be able to detect the
vehicle or pedestrian ahead. In these
cases, the AEB system may not operate
normally. The driver must pay careful
attention in the following situations where
the AEB operation may be limited.
Detecting vehicles
The sensor may be limited when:
- The radar sensor or camera is blockedwith a foreign object or debris.
- Inclement weather such as heavy rain or snow obscures the field of view of
the radar sensor or camera.
- There is interference by electromag- netic waves.
- There is severe irregular reflection from the radar sensor.
- The vehicle in front is too small to be detected by the camera recognition
system (for example a motorcycle or a
bicycle, etc.).
- The vehicle in front is an oversize vehi- cle or trailer that is too big to be detect-
ed by the camera recognition system
(for example a tractor trailer, etc.).
- The driver's field of view is not well illu- minated (either too dark or too much
reflection or too much backlight that
obscures the field of view).
- The vehicle in front does not have their rear lights properly turned ON.
- The outside brightness changes sud- denly, for example when entering or
exiting a tunnel.
(Continued)The brake control may be insuffi-
cient, possibly causing a colli-
sion, if a vehicle in front abruptly
stops. Always pay extreme cau-
tion.
Occupants may get injured, if the
vehicle abruptly stops by the acti-
vated AEB system. Pay extreme
caution.

- The vehicle in front is driving erratical-ly.
- The vehicle drives through a construc- tion area, on an unpaved road, or
above metal materials, such as a rail-
way.
- The vehicle drives inside a building, such as a basement parking lot.
- Driving on a curve
The performance of the AEB system may
be limited when driving on a curved road.
In certain instances on a curved road,
the AEB system may activate premature-
ly.
Also, in certain instances the front radar
sensor or camera recognition system
may not detect the vehicle traveling on a
curved road.
In these cases, the driver 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. - Driving on a slope
The performance of the AEB decreases
while driving upward or downward on a
slope, not recognizing the vehicle in front
in the same lane. It may unnecessarily
produce the warning message and the
warning alarm, or it may not produce the
warning message and the warning alarm
at all.
When the AEB suddenly recognizes the
vehicle in front while passing over a
slope, you may experience sharp decel-
eration.
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 lanes
When a vehicle changes lanes in front of
you, the AEB system may not immedi-
ately 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
stopped vehicle in front of you merges
out of the lane, the AEB 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 you
If the vehicle in front of you has cargo
that extends rearward from the cab, or
when the vehicle in front of you has high-
er ground clearance, additional special
attention is required. The AEB 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.

Driving your vehicle
The LKAS system will not be in the
ENABLED state and the steering
wheel will not be assisted when:
Vehicle speed is below 40 mph (60 km/h) and over 110 mph (180
km/h).
Only one lane line is detected.
The turn signal is turned on before changing a lane. If you change lanes
without the turn signal on, the steering
wheel might be controlled.
The hazard warning flasher is on.
The width of the lane is below 10 feet (3.1 m) and over 15 feet (4.5
m).
ESC (Electronic Stability Control) is activated.
The vehicle is driven on a sharp curve.
The vehicle brakes suddenly.
The vehicle makes sharp lane changes.
Information
When the system is turned on or right
after changing a lane, drive in the middle
of the lane. If not, the system will not pro-
vide steering assist function.
Limitations of the System
The LKAS may operate prematurely
even if the vehicle does not depart from
the intended lane, OR, the LKAS may not
warn you if the vehicle leaves the intend-
ed lane under the following circum-
stances:
The lanes ahead are not visible due torain, snow, water on the road, dam-
aged or stained road surface, or other
factors.
The brightness outside changes sud- denly such as when entering or exiting
a tunnel.
The brightness outside is too low such as when the headlamps are not on at
night or the vehicle is going through a
tunnel.
It is difficult to distinguish the lane marking from the road surface or the
lane marking is faded or not clearly
marked.
Driving on a steep grade, over a hill, or when driving on a curved road.
When light coming from a street light or an oncoming vehicle is reflected on a
wet road surface such as a puddle in
the road.
The windshield or the LKAS camera lens is blocked with dirt or debris. The field of view in front is obstructed
by sun glare.
The lanes are incomplete or the area is in a construction zone.
There are more than two lane lines on the road in front of you.
The lane markings are not clearly visi- ble from the road.
The lane width is too wide or too nar- row. See previous page.
The windshield glass is fogged up; a clear view of the road is obstructed.
There are markings on the road sur- face that look like a lane line that is
inadvertently being detected by the
camera.
There is a boundary structure in the roadway such as a concrete barrier,
guardrail and reflector post that is
inadvertently being detected by the
camera.
There is not enough distance between you and the vehicle in front to be able
to detect the lane line or the vehicle
ahead is driving on the lane line.
The adverse road conditions cause excessive vehicle vibrations while driv-
ing.
