Section 8
HeadWay Monitoring and Warning (HMW)
8.1. What is HMW?
The Mobileye C2-270 Headway Monitoring and Warning monitors the driving distance
from the vehicle in front of you (headway) and alerts you when the headway is less
than a pre-defined threshold. Headway is measured in seconds, and not physical
distance. The headway is the number of seconds it would take for your vehicle
to reach the current position of the vehicle ahead. Mobileye C2-270 continuously
calculates your headway and displays it numerically on the Display Unit. A two-
second headway, in clear weather, is usually considered a safe distance.
8.2. A Headway Warning is Generated When…
A headway warning is initiated when the headway value is less than a pre-defined
threshold. This value is configurable by the user.
8.3. HMW Visual Alert
The Headway Meter displays the Headway distance in seconds. As long as there is a
vehicle ahead of you in your lane, the Headway Meter’s displayed value is continuously
updated. If no headway value is displayed, the vehicle in front of you is more than
2.5 seconds away.
Headway Meter (in Seconds)
There are 2 HMW visual alerts, shown in the following illustration, issued according
to the proximity of the two vehicles:
Notice – A green car icon is displayed from the moment the system detects a vehicle
in front of your car and as long as the headway remains greater than 0.6 second.
Warning! – A red car icon is displayed when headway is less than 0.6 seconds. This is
dangerous tailgating, and the distance between the two cars is perilous.

14
8.4. HMW Audio Alert
A single chime is sounded to draw your attention to a dangerous headway situation.
The timing of the warning can be customized by the user. (Please refer to Section
10.1.3 for customization instructions.)
8.5. HMW Activation
The visual indication is displayed whenever a car traveling in front of your vehicle is
detected. The audio alert and numerical display are active when you are driving at
speeds greater than 30 km/h (19 mph).
8.6. When are HMW Audio Warnings Not Generated?
While Headway Monitoring and Warning visual indications cannot be disabled, it
is possible to mute this function’s audio alert. HMW will not issue audio warnings
when:
lYou drive at speeds below 30 km/h (19 mph).
lThe Mobileye C2-270 volume level has been set to "0" or the System has been
‘muted’.
Beseitigung von Problemen und Fehlern
Notice WARNING!
HMW visual alerts
NOTES:
When a passing vehicle cuts in front of you in your lane and drives away,
a HMW alert is not generated.

15
8.7. Changing the Timing of the Headway Audio Alert
The timing of HMW audio warning is set by default to 0.6 seconds. Yo can change
this setting to any value between 0.1 and 2.5 seconds. To learn how to change the
Headway Warning timing, refer to paragraph 10.1.3.
WARNING!
l
Never configure Mobileye C2-270 while driving!
l
Setting the timing of the headway alert to a low value will activate
the alert when vehicles are very close. You are always solely
responsible for maintaining a safe driving distance from vehicles
ahead, regardless of Mobileye C2-270 warnings or lack of them.

WARNING!
When the Mobileye C2-270 is turned OFF, no warnings will be issued.
10.1. Mode Selection ( )
This button lets you adjust the following functionalities:
lSystem On/OFF
lDisplay Unit Brightness Level
lTiming of HMW audio alerts
lSensitivity of LDW alerts
lSensitivity of PCW alerts
10.1.1. System ON/OFF
To turn OFF the Mobileye C2-270, press and hold the ( ) button for 1.5 seconds
until the system shuts off.
To turn ON the Mobileye C2-270 again, press any button once.

19
NOTE: The Mobileye C2-270 identifies day and night conditions and automatically
switches between ‘Day’ and ‘Night’ modes. Each mode has its own independent
luminance level that can be configured separately. The system saves the latest
luminance settings for both ‘Day’ and ‘Night’ modes until they are changed, or
until reset to factory defaults.
10.1.3. Setting HMW Alert Timing
By default, the HMW audio alert is sounded when headway is less than 0.6 seconds. If
you wish to have the audio warning sounded earlier (at a greater headway distance),
or later (at a shorter headway), the HMW audio alert timing can be changed to a value
between 0.1 and 2.5 seconds.
WARNING!
Do not change Mobileye C2-270 settings while driving.
To set HMW audio alerts timing perform the following steps:
1. Press the ( ) button twice. This will change the system mode to "HMW
Configuration" mode. This mode will be indicated by a very slow flashing red car
icon (dim inn and dim out) and the HW warning level should be displayed by the
seven segments.
2. Press the “+” and “-” buttons to increase or decrease timing.
NOTE: Increasing the timing means the HMW audio alert will be sounded while
your vehicle is at a greater distance from the vehicle ahead than when the default
settings are in effect. If you decrease the timing, the alert will be activated when
your car is relatively close to the vehicle ahead. For example, setting the HMW
audio alert value to 1.2 seconds will cause the system to sound a warning when
headway reaches 1.2 headway seconds or less.
CAUTIONS:
Setting the Headway Monitoring Warning to a low value will generate
an alert only when you are very close to the vehicle ahead

20
10.1.4. Setting LDW Alerts Sensitivity
LDW alerts are issued, by default, up to 0.5 seconds before you swerve out of the lane,
without signaling. You can modify LDW alerts by changing LDW sensitivity. There are
three LDW sensitivity levels: 0, 1, and 2.
Level 2 is the default. Reducing sensitivity to level 1 will delay the LDW alerts, and
setting the system to "0" will turn off LDW alerts.
CAUTIONS:
l
If you set LDW sensitivity to “0”, it will disable LDW alerts.
l
To enable LDW alerts, make sure the LDW sensitivity level is set to
either level 1 or 2.
NOTE: Increasing LDW sensitivity means the LDW alerts will be issued when you
have not yet verged from the lane (either physically, or in terms of time to lane
crossing). Decreasing LDW sensitivity will let you get relatively closer to the lane
marking (either physically, or in terms of time to lane crossing), before the alert is
activated. If you select level 1, the warning line is pushed outwards by 20 cm.
To set the LDW sensitivity level perform the following steps:
1. Press the ( ) button three times. This will change the system mode into “LDW
Sensitivity” configuration mode. The “Right/Left Deviation Alert” icons will flash at
a very slow phase (dim inn and dim out) and the LDW level should be displayed by
the right digit of seven segments.
2. Press the “+” and “-” buttons to increase or decrease sensitivity.
WARNING!
Do not change Mobileye C2-270 settings while driving.
10.1.5. Setting PCW Alerts Sensitivity
You can modify PCW alerts by changing the PCW sensitivity. There are 3 PCW
sensitivity levels: 0, 1 and 2. Level 2 is the default. Reducing sensitivity to level 1 will
delay the PCW alerts. Settign the PCW sensitivity to 0 will disable all PCW warnings.
WARNING!
Do not adjust Mobileye C2-270 controls while driving!
