Driving

Risk of undesirable operation

Operating limits

Active Safety Brake

The system should be deactivated in the

following situations:

with Collision Risk Alert

and Intelligent emergency

braking assistance

The system may issue an alert when the

vehicle is travelling on a long, straight road

with smooth road surface even if the driver

thinks they are holding the steering wheel

correctly.

► Driving with a "space-saver" type spare

wheel.

► When towing or with a bicycle carrier

attached to a towing device, particularly

whena trailer is not connected or the

trailer is not an approved type.

For more information, refer to the General

recommendations on the use of driving

and manoeuvring aids.

The system may not operate or may produce

unsuitable corrections to the steering in the

following situations:

► Adverse weather conditions.

► Wearing thick gloves (with Drive Assist Plus

2.0).

► Driving on slippery road surfaces (risk of

aquaplaning, snow, ice).

► Poor visibility (insufficient road lighting,

snowfall, rain, fog).

► In roadworks or toll booth areas.

► Driving on racing circuits.

► Driving on a rolling road.

This system:

► Dazzle (headlamps of an oncoming vehicle,

low sun, reflections on a wet road surface,

leaving a tunnel, alternating light and shade).

► warns the driver that their vehicle is at risk

of collision with the preceding vehicle, a

pedestrian or a cyclist.

► Windscreen area in front of the camera

dirty, misted up, frost-covered, snow-covered,

damaged or covered by a sticker.

► reduces the vehicle's speed to avoid a

collision or to limit its severity.

Malfunction

In the event of a malfunction, the

Service warning lamp comes on and

this (orange) symbol appears on the

instrument panel, accompanied by the

display of a message and an audible

signal.

► Lane markings eroded, partially hidden

(snow, mud) or multiple (roadworks, surface

joints).

The system also takes motorcyclists into

account.

It may also react on animals. Animals

(especially animals smaller than 0.5 m) and

objects on the road are not necessarily

detected.

► Travelling in a tight bend.

► Winding roads.

Have it checked by a PEUGEOT dealer or a

qualified workshop.

► Presence of a tarmac joint on the road.

This system includes three functions:

► Collision Risk Alert.

► Intelligent emergency braking assistance

(iEBA).

► Active Safety Brake (automatic emergency

braking).

127

Driving

the automatic braking system is not

available.

The system performance may be degraded or

not available by:

This is a normal behavior indicating that a

condition is not fulfilled and which does not

request the support of a workshop.

In any situations with ignition on where

automatic braking presents a risk, deactivating

the system via the driving aids touch screen

application is recommended, for instance:

► Sensor covered with snow, ice, slush, mud or

dirt.

► Windscreen damaged or smeared, with

blurred view or covered with foreign items

(e.g. stickers).

► Damaged front bumper (or deformed in the

past) or covered with foreign items (e.g.

stickers).

The vehicle has a multifunction camera located

at the top of the windscreen and, depending on

version, a radar located in the front bumper.

► Carrying long objects on roof bars.

► Using an automatic car wash.

► Front camera out of regular position or

missing cover.

This system does not replace the need for

driver vigilance.

This system is designed to assist the driver

and improve road safety.

It is the driver's responsibility to continuously

monitor traffic conditions in accordance with

applicable driving regulations.

► Performing any maintenance (e.g. changing

a wheel, working inside the engine

compartment).

► Brake discs cooling process is on-going.

► In curves.

► Placing the vehicle on a rolling bench in a

workshop.

► System initialization process after battery

disconnection.

► Towing the vehicle.

► Sun or lights shining into the front camera

lens.

► Following a damage of the windscreen close

to the detection camera.

As soon as the system detects a potential

collision, it prepares the braking circuit.

This may cause a slight noise and a slight

sensation of deceleration.

► Adverse environmental conditions (e.g. rain,

fog or snow).

The system is automatically deactivated if:

► Vehicle ahead creating road spray.

The system performance may be affected by:

► Vehicle stability system in progress.

► Vehicle battery voltage out of range.

► Wet road reflecting lights.

►

A spare wheel with a too small

diameter is detected.

Operating conditions and

limits

► A fault with the brake pedal switch or with

the right or left brake lamp is detected.

Brake system operational.

ASR system activated.

Seat belts fastened for all passengers.

Stabilised speed on roads with no or low

curvature.

► A fault in the sensors, in the electronic or

in the brake system is detected.

► Close vehicles ahead.

► A trailer is detected by the equipped

vehicle hitch (with an electrical connection

plug).

► Tractors, muddy vehicles or vehicles with a

trailer.

This warning lamp lights up on

the instrument panel without any

additional message, to indicate that

► A severe crash (e.g. with airbag

deployment) is detected.

► Banked roads.

► Winding or hilly roads.

128

Driving

Operation

► Poor lighting conditions.

If you select "Far" in the touch screen,

Depending on the collision risk detected by the

system and the alert trigger threshold chosen

by the driver, different levels of alert may be

triggered and displayed on the instrument panel.

The system takes into account the vehicle

dynamics, the difference speed of the own

vehicle and the object identified for the collision

risk, and the operation of the vehicle (e.g.

actions on the pedals, steering wheel) to trigger

the alert at the most relevant moment.

then the system warns sooner. This

increases the safety but increases also the

amount of alerts, if the legal safety distance is

not kept.

To reduce the alert occurrence, you can

change the setting to either of the other two.

► Sudden lighting changes.

► Vehicle modifications (e.g. tyres).

In case the detection is degraded or

temporarily unavailable by environment

conditions, then a driver indication is not

displayed (because a driver action is not

requested).

Intelligent emergency

braking assistance (iEBA)

(orange) Level 1: visual alert only,

warning that the preceding vehicle is

very close.

The message "Vehicle close" is

displayed.

(red) Level 2: visual and audible alert,

warning that a collision is imminent.

The message "Brake!" is displayed.

Level 3: a micro-braking may be

given, confirming the risk of collision

(optional).

It can be dangerous to drive if the brake

lamps are not in perfect working order.

This function increases vehicle deceleration if

the driver does not brake enough to avoid a

collision.

This assistance is only provided if the driver

presses the brake pedal.

The driver must not overload the vehicle

(keep within the GVW and GTW limits and

load height limits for roof bars).

Active Safety Brake

Collision Risk Alert

This function warns the driver if there is a risk

of collision with the preceding vehicle, or with a

pedestrian or cyclist.

Modifying the alert trigger threshold

The trigger threshold determines the sensitivity

with which the function warns of the risk of

collision.

While approaching a vehicle too quickly,

the level 2 alert may be displayed directly.

Important: the level 1 alert depends on the

trigger threshold selected. It reacts only on

moving vehicles. It is disabled automatically

at lower speed.

► In the ADAS touch

screen application, select

Functions>Automatic Braking

System.

It is possible that collision warnings are

not given, are given too late or seem

unjustified.

► Select one of the 3 preset thresholds: "Far",

"Medium" or "Near".

The driver must always stay in control of the

vehicle and be prepared to react at any time

to avoid an accident.

The selected threshold is memorised when the

ignition is switched off.

This function, also called "automatic emergency

braking", intervenes after the acoustic alert if the

129

Driving

driver does not operate the brake pedal quickly

enough.

The system aims at reducing the speed of

impact or avoiding a collision if the driver fails

to react.

With an automatic gearbox or drive selector, in

the event of automatic emergency braking, keep

the brake pedal depressed, also after a complete

stop is reached, to prevent the vehicle from

rolling away.

► The vehicle speed is between 5 and 15 mph

(8 and 25 km/h).

► A collision on the side of the other vehicle is

probable.

The system also takes into account motorcyclists

and may react accordingly.

Below a speed of 19 mph (30 km/h),

automatic emergency braking may slow

down the vehicle to a complete stop.

Otherwise, for versions with camera only, the

speed may be reduced by a maximum of 16

mph (25 km/h).

The driver can override the automatic

emergency braking at any time by

strongly turning the steering wheel (evasive

manoeuver) and/or by firmly pressing the

accelerator pedal.

Deactivation/Activation

By default, the system is automatically activated

at every ignition cycle.

For versions with camera and radar, the

speed reduction may be extended to 31 mph

(50 km/h), if both sensors are able to detect

the thread.

It is configured in the ADAS touch

screen application.

The brake pedal may feel hard and vibrate

slightly while the function is operating.

If the vehicle comes to a complete stop,

automatic braking is maintained for 1 to 2

seconds.

Deactivation of the system is

signalled by the illumination of

this warning lamp, accompanied by

the display of a message in the

instrument panel.

Operation

The system operates subject to the following

conditions:

Turning scenarios

Crossing road with another vehicle

► The vehicle's speed does not exceed 5 mph

and 50 mph (8 km/h and 80 km/h), when a

pedestrian or a cyclist is detected.

The system cannot be deactivated above

10 km/h.

► The vehicle's speed does not exceed 5 mph

and 50 mph (8 km/h and 80 km/h), when a

stationary vehicle is detected.

Malfunction

This warning lamp lights up on the

instrument panel with the message

"Audible Warning System fault:

Repair needed" if the audible

warning system is in failure.

► The vehicle's speed is between 6 mph and

53 mph (10 km/h and 85 km/h) (versions with

camera only) or 5 mph and 87 mph (8 km/h

and 140 km/h) (versions with camera and

radar) when a moving vehicle is detected.

The system may operate when the vehicle is

turning and detects another vehicle, on the

adjacent lane, approaching from the opposite

direction if:

The system may be disturbed or unavailable.

Have it checked by a PEUGEOT dealer or a

qualified workshop.

This warning lamp flashes (for

approximately 10 seconds) as soon

as the function applies the vehicle’s

brakes.

activated.

► Then the vehicle is about to cross the path of

another vehicle.

This warning lamp lights up on the

instrument panel with the message

"Driving Assistance Sensor blind:

During the flashing time, the function is not

available.

130

Driving

Clean sensor, see User Manual" if

the sensor is masked.

As soon as the speed of the vehicle drops

below 40 mph (65 km/h), the system goes

into standby.

Driving time starts being counted again once

the speed reaches above 40 mph (65 km/h).

Distraction detection

This is a normal behavior, which does not

request the support of a qualified workshop.

In this case, stop the vehicle and verify if the

front camera or the front radar is covered by dirt,

mud, sand, snow, ice or anything preventing the

sensing.

For more information, refer to the General

recommendations on the use of driving

and manoeuvring aids.

The function comprises the "Driver Attention

Warning" system combined with the "Driver

Attention Warning by Camera" system.

Driver Attention Warning by

Camera

The system is operational again after the

detection field has been cleaned.

These systems are in no way designed to

keep the driver awake or to prevent the

driver from falling asleep at the wheel.

It is the driver’s responsibility to stop if feeling

tired.

In the event of a malfunction, this

warning lamp lights up on the

instrument panel, accompanied by the

display of a message and an audible

signal.

Take a break if you are feeling tired or at least

every 2 hours.

Have it checked by a PEUGEOT dealer or a

qualified workshop.

These systems reset themselves if one of the

following conditions is met:

If these warning lamps

come on after the engine

has been switched off and

then restarted, contact a

PEUGEOT dealer or a

qualified workshop to have

the system checked.

► The ignition has been switched off for a few

minutes.

The system assesses the driver's

level of alertness, fatigue and

distraction by identifying trajectory

changes in relation to the lane

markings.

► The driver's seat belt is unfastened and their

door is opened.

These warning lamps light

up on the instrument pan-

el to indicate that the driv-

er's and/or front passeng-

er's seat belt is not fas-

tened (depending on ver-

sion). The automatic brak-

ing system is deactivated

until the seat belts are fas-

tened.

Driver Attention Warning

To do this, the system uses a camera, placed on

the upper part of the windscreen.

This system is particularly suited to fast roads

(speed higher than 40 mph (65 km/h)).

The system triggers an alert when it

detects that the driver has not taken

a break after two hours of driving at a

speed above 40 mph (65 km/h).

The system may perform a learning

procedure for up to 5 minutes after the

start of the monitoring.

During this period, the driver's individual

driving behaviour is analysed and no alert is

given.

This alert is issued via the display of a

message encouraging the driver to take a break,

accompanied by an audible signal.

If the driver does not follow this advice, the alert

is repeated hourly until the vehicle is stopped.
