Opel Astra (2019 year). Instruction - part 13

198

Driving and operating

On Uplevel display, select Info menu

via steering wheel buttons and press

o

 to select following distance

indication 3 115.
The minimum indicated distance is

0.5 seconds.
If there is no vehicle ahead or the

vehicle ahead is out of range, two

dashes will be displayed: -.- sec.

If Adaptive cruise control is active,

this page shows the alert sensitivity

setting instead of following distance

setting. 3 187.

Active emergency braking

Active emergency braking can help to

reduce the damage and injury from

crashes with vehicles and obstacles

directly ahead, when a collision can

no longer be avoided either by

instruction braking or by steering. Before

the active emergency braking

applies, the driver is warned by the

forward collision alert 3 195.
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

pedestrians or 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 85 km/h.
With radar sensor active emergency

braking operates in forward gear

above walking speed at all speeds.
A precondition is that forward collision

alert with front camera system is not

deactivated by pressing V on the

steering wheel 3 195 or, with radar

sensor, that it is not deactivated in the

vehicle personalisation menu 3 125.
The system includes:

● brake preparation system
● emergency automatic braking

Driving and operating

199

● 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

pressurizes the brakes. This reduces

the response time, when a instruction 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.

Emergency automatic braking

After activation of brake preparation

system and just before the imminent

collision, this function automatically

applies limited braking to reduce the

impact speed of the collision or

prohibit a crash. Depending on the

situation, the vehicle may

automatically brake moderately or

hard. This front automatic braking can

only occur if a vehicle ahead is

detected, indicated by the vehicle

ahead indicator A 3 195.
If equipped only with front camera the

system operates up to a speed of 60

km/h.
Below a speed of 40 km/h the system

can apply full braking.
Emergency automatic braking may

slow the vehicle to a complete stop to

try to avoid a potential crash. If this

happens, emergency automatic

braking may engage the electric

parking brake to hold the vehicle at a

stop. To release press the electric

parking brake button or firmly press

the accelerator pedal.

9 Warning

Emergency automatic braking is

an emergency crash preparation

feature and is not designed to

avoid crashes. Do not rely on the

system to brake the vehicle.

Emergency automatic braking will

not brake outside of its operating

speed range and only responds to

detected vehicles.

Forward looking brake assist

In addition to the brake preparation

system and emergency automatic

braking, the forward looking brake

assist function makes the brake assist

more sensitive. Therefore, pressing

the brake pedal less strongly results

in immediate hard braking. This

function helps the driver brake

quicker and harder before the

imminent collision.
If equipped only with front camera the

system operates up to a speed of 85

km/h.

9 Warning

Active emergency braking is not

designed to apply hard

autonomous braking or to

automatically avoid a collision. It is

designed to reduce the vehicle

speed before a collision. It may not

react for pedestrians or animals.

200

Driving and operating

After a sudden lane change, the

system needs a certain time to

detect the next preceding vehicle.
The complete attention of the

driver is always required while

driving. The driver shall always be

ready to take action and apply the

brakes and steer to avoid

collisions. The system is designed

to work with all occupants wearing

their seat belts.

Intelligent Brake Assist

If the vehicle is equipped with radar

sensor Intelligent brake assist may

activate when the brake pedal is

applied quickly by providing a boost

to braking based on the speed of

approach and distance to a vehicle

ahead.
Minor brake pedal pulsations or pedal

movement during this time is normal

and the brake pedal should continue

to be applied as needed. Intelligent

brake assist will automatically

disengage only when the brake pedal

is released.

9 Warning

Intelligent brake assist may

increase vehicle braking in

situations when it may not be

necessary. You could block the

flow of traffic. If this occurs, take

your foot off the brake pedal and

then apply the brakes as needed.

Deactivation

On vehicles with front camera active

emergency braking can be

deactivated by repeatedly pressing

the gap switch V to Off setting,

3

 195. If deactivated a message is

displayed in the Driver Information

Centre.
On vehicles with radar sensor the

system can be disabled in the

personalisation menu in the Info-

display, 3 125.
We recommend to deactivate the

system in the vehicle personalisation

in the following cases:

● when the vehicle is being towed
● before using an automatic car

wash with ignition switched on

● if the windscreen has been

damaged close to the camera

● if the front bumper has been

damaged

System limitations

In some cases, the active emergency

braking system may provide an

automatic braking in situations that

seem to be unnecessary, for instance

in parking garages, due to traffic signs

in a curve or due to vehicles in

another lane. This is normal

operation, the vehicle does not need

Driving and operating

201

service. Firmly apply the accelerator

pedal to override the automatic

braking.
Emergency automatic braking may

not:

● detect a vehicle ahead on

winding or hilly roads.

● detect all vehicles, especially

vehicles with a trailer, tractors,

muddy vehicles, etc.

● detect a vehicle when weather

limits visibility, such as in fog,

rain, or snow.

To avoid malfunction keep the areas

of the camera sensor in the

windscreen and the radar sensor in

the radiator grille always clean from

dirt, dust, ice and snow.
Complete attention is always required

while driving, and you should be

ready to take action and apply the

brakes and/or steer the vehicle to

avoid crashes.

Basic notes on parking assist

systems

9 Warning

Under certain circumstances,

various reflective surfaces on

objects or clothing as well as

external noise sources may cause

the system to fail to detect

obstacles.
Special attention must be paid to

low obstacles which can damage

the lower part of the bumper.

Caution

Performance of the system can be

reduced when sensors are

covered, e.g. by ice or snow.
Performance of the parking assist

system can be reduced due to

heavy loading.
Special conditions apply if there

are taller vehicles in the vicinity

(e.g. off-road vehicles, mini vans,

vans). Object identification and

correct distance indication in the

upper part of these vehicles

cannot be guaranteed.
Objects with a very small reflection

cross-section, e.g. objects of

narrow size or soft materials, may

not be detected by the system.

Parking assist systems do not

detect objects outside the

detection range.

Note

It is possible that the sensor detects

a non-existing object caused by

echo disturbance from external

acoustic noise or mechanical

misalignments (sporadic false

warnings may occur).
Make sure that the front number

plate is properly mounted (not bent

and no gaps to the bumper on the left

or right side) and the sensors are

firmly in place.
Advanced parking assist system

may not respond to changes in the

available parking space after

initiating a parking manoeuvre. The

system may recognize an entry, a

gateway, a courtyard or even a

crossing as a parking slot. After

selecting reverse gear the system

will start a parking manoeuvre. Take

care regarding the availability of the

suggested parking slot.

Driving and operating

209

Surface irregularities, e.g. on

construction zones, are not detected

by the system. The driver accepts

responsibility.
Note

After production, the system

requires a calibration. For optimal

parking guidance, a driving distance

of at least 10 km, including a number

of bends, is required.

Side blind spot alert

The Side blind spot alert system

detects and reports objects on either

side of the vehicle, within a specified

"blind spot" zone. The system

displays a visual alert in each exterior

mirror, when detecting objects that

may not be visible in the interior and

exterior mirrors.
Side blind spot alert uses some of the

advanced parking assist sensors

which are located in the front and rear

bumper on both sides of the vehicle.

9 Warning

Side blind spot alert does not

replace driver vision.
The system does not detect:

● vehicles outside the side blind

zones which may be rapidly

approaching

● pedestrians, cyclists or animals

Before changing a lane, always

check all mirrors, look over the

shoulder and use the turn signal.

When the system detects a vehicle in

the side blind zone while driving

forwards, either while passing a

vehicle or being passed, a yellow

warning symbol B will illuminate in

the relevant exterior mirror. If the

driver then activates the turn signal,

the warning symbol B starts flashing

yellow as a warning not to change

lanes.

Note

If the overtaking vehicle is at least

10 km/h faster than the vehicle being

overtaken, the warning symbol B in

the relevant exterior mirror may not

illuminate.

Side blind spot alert is active from

speeds of 10 km/h up to 140 km/h.

Driving faster than 140 km/h

deactivates the system, indicated by

low lighting warning symbols B in

both exterior mirrors. Reducing the

speed again will extinguish the

warning symbols. If a vehicle is then

detected in the blind zone, the

warning symbols B will illuminate as

normal on the relevant side.

210

Driving and operating

When the vehicle is started, both

exterior mirror displays will briefly

illuminate to indicate that the system

is operating.
The system can be activated or

deactivated in the Info-Display.

Vehicle personalisation 3 125.
Deactivation is indicated by a

Centre.

Detection zones

The detection zones start at the rear

bumper and extend approx.

three metres rearwards and to the

sides. The height of the zone is

approx. between half a metre and

two metres off the ground.
The system is deactivated if the

vehicle is towing a trailer or if a bike

carrier is attached.
Side blind spot alert is designed to

ignore stationary objects, e.g.

guardrails, posts, curbs, walls and

beams. Parked vehicles or oncoming

vehicles are not detected.

Fault

Occasional missed alerts can occur

under normal circumstances and will

increase in wet conditions.
