2020 OPEL ASTRA K cruise control

Driving and operating187Fault
If the adaptive cruise control does not work due to temporary conditions
(e.g. blockage by ice, overheated
brakes or low speed manoeuvres) or
if there is a permanent system error,
then a message is displayed in the
Driver Information Centre.
Vehicle messages 3 122.
Forward collision alert The forward collision alert may help toavoid or reduce the harm caused by
front-end crashes.
If the vehicle is equipped with
conventional cruise control, the
forward collision alert uses the front
camera in the windscreen to detect a
vehicle directly ahead, in your path.
If the vehicle is equipped with
adaptive cruise control, the forward
collision alert uses the radar sensor to detect a vehicle directly ahead, in
your path.
Number plate mounting 3 222
A vehicle ahead is indicated by the
control indicator A.
If a vehicle directly ahead is
approached too quickly, a warning
chime and alert in the Driver
Information Centre is provided.
A precondition is that forward collision
alert with front camera system or
radar sensor is not deactivated in the
vehicle personalisation menu 3 124.
Activation
Forward collision alert with front
camera detects vehicles to distances
and operates automatically at all
speeds above walking speed.
Forward collision alert with radar
sensor detects vehicles to distances
and operates automatically at all
speeds above walking speed.
Alerting the driver
The vehicle ahead control indicator
A illuminates green in the instrument
cluster when the system has detected
a vehicle in the driving path.
The control indicator A changes to
yellow when the distance to a
preceding moving vehicle gets too
small or when approaching another
vehicle too rapidly.Caution
The colour lighting of this control
indicator does not correspond to
local traffic laws on following
distance. The driver bears full
responsibility for maintaining safe
following distance according to
applicable traffic rules, weather
and road conditions etc. at all
times.

188Driving and operatingWhen the time to a potential collision
with a vehicle in front gets too small
and a collision is imminent, the
collision alert symbol pops-up in the
Driver Information Centre and the
driver gets notified by a warning
chime sound.
Depress the brake pedal and steer
the vehicle, if it is required by the
situation.
Selecting the alert sensitivity
Press V or E to set the alert
sensitivity to near, medium or far.The first button press shows the
current setting on the Driver
Information Centre. Additional button
presses will change this setting. The
chosen setting will remain until it is
changed. The alert timing will vary based on vehicle speed. The faster
the vehicle speed, the farther away
the alert will occur. Consider traffic
and weather conditions when
selecting the alert timing.
Note that the alert timing sensitivity
setting is shared with the following
distance setting of the adaptive cruise control. So changing the alert timing
sensitivity changes the adaptive
cruise control following distance
setting.
Deactivation The system can be deactivated by the
personalisation menu 3 124.
If the forward collision alert was
deactivated, alert sensitivity is set to
"medium" when ignition is switched on next time.
The last selected setting will be stored when the ignition is switched off.
General information9 Warning
Forward collision alert is just a
warning system and does not
apply the brakes. When
approaching a vehicle ahead too
rapidly, it may not provide you
enough time to avoid a collision.
The driver accepts full
responsibility for the appropriate
following distance based on traffic, weather and visibility conditions.

190Driving and operating
If Adaptive cruise control is active,
this page shows the alert sensitivity
setting instead of following distance setting 3 179.
Active emergency braking Active emergency braking can help toreduce the damage and injury from
crashes with vehicles and obstacles
directly ahead, when a collision can
no longer be avoided either by
manual braking or by steering. Before
the active emergency braking
applies, the driver is warned by the forward collision alert 3 187.
The feature uses various inputs (e.g.
camera sensor, radar sensor, brake
pressure, vehicle speed) to calculate
the probability of a frontal collision.9 Warning
This system is not intended to
replace the driver responsibility for driving the vehicle and looking
ahead. Its function is limited to
supplemental use only to reduce
the vehicle speed before a
collision.
The system may not react for
animals. After a sudden lane
change, the system needs a
certain time to detect the next
preceding vehicle.
The driver shall always be ready to take action and apply the brakes
and steer to avoid collisions.
Functionality
If equipped only with front camera the active emergency braking operates in
forward gear above walking speed up to 80 km/h.
With radar sensor active emergency
braking operates in forward gear
above walking speed at all speeds.
Number plate mounting 3 222.
A precondition is that forward collision
alert is not deactivated in the vehicle
personalisation menu 3 124.
The system includes: ● brake preparation system
● emergency automatic braking
● forward looking brake assist
● intelligent brake assist (only with radar sensor)
Brake preparation system When approaching a vehicle ahead
so quickly that a collision is likely, the
brake preparation system slightly
pressurises the brakes. This reduces
the response time, when a manual or automatic braking is requested.
The brake system is prepared so that braking can occur more rapidly.
If equipped only with front camera the
system operates up to a speed of
80 km/h.

194Driving and operatingDetecting front pedestrian ahead
A pedestrian ahead up to a distance
of approx. 40 m is indicated by the
control indicator 7 in the instrument
cluster.
Front pedestrian alert
When approaching a detected
pedestrian too quickly, the collision
alert symbol pops up in the Driver Information Centre. A warning chime
is provided. The brake system may
prepare for driver braking to occur
more rapidly which can cause a brief, mild deceleration. Continue to apply
the brake pedal as required.
Cruise control or Adaptive cruise
control may be disengaged when the Front pedestrian alert occurs.
Automatic braking If a crash into a pedestrian directlyahead is imminent, and the brakes
have not been applied, Automatic
braking may automatically brake
moderately or brake hard. This can
help to avoid some very low speed
pedestrian crashes or reduce
pedestrian injury.
Automatic braking levels may be reduced under certain conditions,
such as higher speeds.
If this happens, automatic braking
may engage the Electric parking
brake to hold the vehicle at a stop.
Release the parking brake. Pressing
the accelerator pedal will also release Automatic braking and Electric
parking brake 3 171.
This system includes Intelligent brake assist, and the Emergency automatic
braking system may also respond to
pedestrians.
Active emergency braking 3 190.Automatic braking can be disabled in
the vehicle personalisation menu
3 124.
General information9 Warning
The driver must always be ready
to take action and apply the brakes and steer to avoid collisions.
9 Warning
Front pedestrian braking may alert
or automatically brake the vehicle
suddenly in situations where it is
unexpected and undesired. It
could falsely alert or brake for
objects similar in shape or size to
pedestrians, including shadows.
This is normal operation and the
vehicle does not need a service.
To override Automatic braking,
firmly depress the accelerator
pedal, if it is safe to do so.
