The IEB system has some performance limita-
tions.

–
Interference by other radar sources.
In these cases, the system may not be able to
warn the driver properly. Be sure that you
check, clean and clear sensor areas regularly.
•
•
The camera area of the windscreen is
fogged up, covered with dirt, water drops,
ice, snow, etc.
–
If a stationary vehicle is in the vehicle's
path, the IEB system will not function when
the vehicle is driven at speeds over
approximately 80 km/h (50 MPH).
In some road or traffic conditions, the IEB sys-
tem may unexpectedly apply partial braking.
When acceleration is necessary, continue to
depress the accelerator pedal to override the
system.
•
–
–
Strong light (e.g. sunlight or high beams
from oncoming vehicles) enters the front
camera. Strong light causes the area
around the pedestrian or cyclist to be cast
in shadow, making it difficult to see.
–
For pedestrian and cyclist detection, the
IEB system will not function when the ve-
hicle is driven at speeds over approxi-
mately 80 km/h (50 MPH) or below
approximately 10 km/h (6 MPH). The auto-
matic brake operates at speeds below 60
km/h (37 MPH).
Excessive noise will interfere with the warning
chime sound, and the chime may not be heard.

The Intelligent Emergency Braking system
may operate when the following are similar to
the outlines of pedestrians or cyclists, or if
they are the same size and position as a vehi-
cle's and motorcycle's tail lights.
The IEB system may not function for pedestri-
ans and cyclists in darkness or in tunnels, even
if there is street lighting in the area.

The poor contrast of a person to the back-
ground, such as having clothing coloured
or patterned similar to the background.
The IEB system may not function if the vehicle
ahead is narrow (e.g. a motorcycle).

The pedestrian's profile is partially ob-
scured or unidentifiable due to the pedes-
trian transporting luggage, wearing bulky
or very loose-fitting clothing or accesso-

Paint, a shadow or a pattern on the road,
roadside or wall (including faded and un-
usual road markings).
The IEB system may not function if the speed
difference between the two vehicles is too
small.
–
A shape formed by road structures ahead
(such as tunnels, viaducts, traffic sign, re-
flectors installed on the side of vehicles, re-
flection sheets, and guardrails), road side
objects (trees, buildings) and light sources.
The IEB system may not function properly or
detect a vehicle, pedestrian or cyclist ahead in
the following conditions:
The system performance may degrade in the
following conditions:
•
•
•
–
–
–
The vehicle is driven on a slippery road.
The vehicle is driven on a slope.
–
Poor visibility (conditions such as rain,
snow, fog, dust storms, sand storms, and
road spray from other vehicles).
–
A shape formed by road side objects, such
as trees, lighting, shadows, or buildings.
Excessively heavy luggage is loaded in the
rear seat or the luggage area of your ve-
hicle.

–
Driving on a steep downhill slope or roads
with sharp curves.
The Intelligent Emergency Braking system
may react to:

The system is designed to automatically
check the sensor (radar and camera) function-

may not detect some forms of obstruction of
