Side airbag

Front airbags protect the driver and front pas‐

senger in the event of a head-on collision where

the protection of the seat belts alone would no

longer be sufficient.

In a side-on crash, the side airbag protects the

side of the body in the chest and pelvic area.

Head airbag

The head airbag protects the head in the event

of a side-on crash.

Safety

CONTROLS

▷ Do not glue the airbag covers and do not

cover or modify them in any way.

Protective function

General

Airbags are not activated in every collision, for ex‐

ample, in minor accidents.

▷ Do not use the front airbag cover on the front

passenger's side as a tray.

▷ Do not install seat covers, cushions or other

objects on the front seats if they are not spe‐

cifically designed for use on seats with inte‐

gral side airbags.

Information for optimum airbag

effectiveness

▷ Do not hang items of clothing for example

coats or jackets over the backrests.

WARNING

▷ Do not modify individual components of the

system or its wiring. This also applies to the

covers of the steering wheel, the dashboard

and seats.

If the seat position is incorrect or the deploy‐

ment area of the airbag is restricted, the airbag

system cannot provide the intended level of

protection or may cause additional injuries

when it deploys. There is a risk of injury or even

death. Observe the following to achieve opti‐

mum protective function.

▷ Do not dismantle the airbag system.

Even if all this information is observed, injuries re‐

sulting from contact with the airbag cannot be

entirely ruled out depending on the situation.

▷ Keep a distance from the airbags.

The noise caused by the deployment of an air‐

bag may lead to temporary hearing loss in vehi‐

cle occupants sensitive to noise.

▷ Always grip the steering wheel at the steering

wheel rim. Place your hands in the 3 o'clock

and 9 o'clock positions to minimise the risk of

injury to hands or arms when the airbag de‐

ploys.

Operational readiness of the

airbag system

▷ Adjust the seat and steering wheel so the

driver can reach over the steering wheel diag‐

onally. Select the settings so that, when

reaching over, the shoulders stay in contact

with the backrest and the upper body stays

as far away from the steering wheel as possi‐

ble.

Safety notes

WARNING

Individual components of the airbag system

may be hot after airbag deployment. There is a

risk of injury. Do not touch individual compo‐

nents.

▷ Make sure that the front-seat passenger is

sitting correctly, i.e. with their feet and legs in

the footwell, not resting on the dashboard.

▷ Make sure that vehicle occupants keep their

head away from the side airbag.

WARNING

Work carried out incorrectly can lead to a fail‐

ure, malfunction or accidental deployment of

the airbag system. If there is a malfunction, the

airbag system might not deploy as intended in

an accident, even if the impact is of the appro‐

priate severity. There is a risk of injury or even

death. Have the airbag system tested, repaired

or removed and disposed of by a Service Part‐

▷ Do not place any other persons, pets or ob‐

jects between the airbags and occupants.

▷ Keep the dashboard and windscreen area on

the passenger side clear, for example do not

attach adhesive foil or covers and do not fit

brackets for navigation devices or mobile tel‐

ephones, for example.

Brake intervention

Warning with braking function

Display

If there is a risk of collision with a detected vehi‐

cle, a warning symbol is shown in the instrument

cluster and, if applicable, in the Head-Up Display.

The warning prompts the driver to take action.

When the brake is operated during a warning, the

maximum necessary brake force is applied. Brak‐

ing assistance requires that the brake pedal is

depressed sufficiently quickly and firmly before‐

hand.

Symbol Action

The system can also assist by braking the vehi‐

cle automatically if there is a risk of a collision.

Symbol illuminates red: advance

warning.

At low speeds, the vehicle can be braked to a

stop.

Brake and increase the distance.

Manual transmission: when the vehicle is braked

to a stop, the engine may shut off.

Symbol flashes red and an acoustic

signal sounds: acute warning.

City braking function: brake intervention takes

place at up to approx. 80 km/h, 50 mph.

Brake and perform an evasive ma‐

noeuvre if necessary.

With radar sensor: brake intervention takes place

at up to approx. 250 km/h, 155 mph.

Advance warning

At speeds above approx. 210 km/h, 130 mph,

brake intervention takes the form of a brief jolt.

There is no automatic deceleration.

An advance warning is given for example if there

is an impending risk of collision or the distance

from the vehicle ahead is too short.

Braking can be discontinued either by pressing

the accelerator pedal or by actively moving the

steering wheel.

The driver must intervene personally when an

advance warning is given.

Object detection may be limited. Take into ac‐

count the detection range limits and the func‐

tional limitations.

Acute warning with braking function

An acute warning is given when the vehicle is ap‐

proaching another object at a high differential

speed and there is an immediate risk of a colli‐

sion.

System limits

Safety note

The driver must intervene personally when an

acute warning is given. Depending on the driving

situation and the vehicle's equipment, the acute

warning may be supported by a brief jolt in the

brakes.

WARNING

The system may not respond at all, or may re‐

spond too late, incorrectly or without justifica‐

tion due to system limitations. There is a risk of

accident or material damage. Observe the in‐

formation on the system limits and intervene

actively if necessary.

If the warning time setting is "Late", the jolt does

not occur.

If necessary, the system can also assist by brak‐

ing the vehicle automatically if there is a risk of a

collision.

176

Safety

CONTROLS

▷ If the camera has overheated due to exces‐

sively high temperatures and has been tem‐

porarily deactivated.

Upper speed limit

The system is temporarily disabled at speeds

over approx. 250 km/h, 155 mph. Once the

speed drops back below this threshold, the sys‐

tem becomes responsive again according to its

settings.

▷ Up to 10 seconds after starting the engine

using the Start/Stop button.

▷ During the camera calibration process imme‐

diately after vehicle delivery.

Detection range

▷ If there is sustained glare due to oncoming

light, for example if the sun is low in the sky.

▷ Depending on the vehicle equipment: if the

radar sensors are soiled or covered.

▷ Depending on the vehicle equipment: after

work performed incorrectly on the vehicle

paintwork near to the radar sensors.

Attaching any objects, for example stickers or

decals, in the area of the radar beam will also im‐

pair radar sensor operation and may even cause

them to fail.

Only objects detected by the system are taken

into account.

Sensitivity of the warnings

The detection ability of the system is limited.

The higher the sensitivity of the warning settings,

for example warning time, the more warnings are

displayed. As a result, there may also be an in‐

creased number of premature or unjustified

warnings and responses.

For this reason, the system may fail to respond

or only respond after a delay.

For example it is possible that the following may

not be detected:

▷ Slow-moving vehicle when approaching it at

high speed.

Person warning with light

braking function

▷ Vehicles suddenly cutting in or braking heav‐

ily.

▷ Vehicles with an unusual rear appearance.

▷ Two-wheeled vehicles ahead.

Principle

The system can help to avoid accidents with pe‐

destrians and cyclists. If an accident cannot be

avoided, the system helps to reduce the collision

speed. The system warns of the possible risk of

collision in the urban speed range and brakes au‐

tomatically, as necessary.

Functional limitations

The system may have limited functionality in the

following situations, for example:

▷ In thick fog, wet conditions or snow.

▷ On sharp bends.

▷ When Driving Stability Control Systems are

limited or deactivated, for example DSC OFF.

General

At speeds above approx. 5 km/h, 3 mph, the sys‐

tem warns of the possible risk of collision with

pedestrians and cyclists.

▷ If the field of view of the camera or the wind‐

screen in front of the rear-view mirror is soiled

or covered.

When leaving the lane

If the vehicle leaves the lane and the lane mark‐

ing is detected, the steering wheel vibrates de‐

pending on the steering wheel vibration setting.

▷ If Dynamic Stability Control DSC intervenes.

System limits

Safety note

If the turn indicator is switched on in the corre‐

sponding direction before changing lanes, no

warning is issued.

WARNING

Steering intervention

The system may not respond at all, or may re‐

spond too late, incorrectly or without justifica‐

tion due to system limitations. There is a risk of

accident or material damage. Observe the in‐

formation on the system limits and intervene

actively if necessary.

Depending on the equipment, if a lane marking is

crossed in the speed range up to 210 km/h, ap‐

prox. 130 mph, the system may intervene not

only by vibrating but also with a brief active steer‐

ing intervention. The steering intervention helps

to keep the vehicle in lane. Steering intervention

can be felt at the steering wheel, and can be

overridden manually at any time. With active

steering intervention, the display flashes in the

instrument cluster.

Functional limitations

The system may have limited functionality in the

following situations, for example:

Warning signal

▷ In thick fog, wet conditions or snow.

Depending on the equipment, if the system exe‐

cutes an active steering intervention multiple

times within 3 minutes without the driver touch‐

ing the steering wheel, an acoustic warning is

emitted. A short warning signal sounds on the

second steering intervention. A longer warning

signal sounds from the third steering intervention

onwards.

▷ When there are missing, worn, poorly visible,

merging/separating or ambiguous lane mark‐

ings; for example, in areas where there are

roadworks.

▷ If lane markings are covered by snow, ice, dirt

or water.

▷ On sharp bends or narrow roads.

▷ If lane markings are not white.

A Check Control message is also displayed.

▷ If lane markings are obscured by objects.

▷ If the vehicle is too close to the vehicle ahead.

The warning signal and Check Control message

tell the driver to pay more attention to the lane.

183

Safety

CONTROLS

▷ If there is sustained glare due to oncoming

light, for example if the sun is low in the sky.

The light in the exterior mirror illuminates at a

dimmed level.

▷ If the field of view of the camera or the wind‐

screen in front of the rear-view mirror is soiled

or covered.

Before changing lanes with the turn indicator

switched on, the system issues a warning in the

above situations.

▷ If the camera has overheated due to exces‐

sively high temperatures and has been tem‐

porarily deactivated.

The light in the exterior mirror flashes and the

steering wheel vibrates.

▷ Up to 10 seconds after starting the engine

using the Start/Stop button.

Safety notes

▷ During the camera calibration process imme‐

diately after vehicle delivery.

WARNING

The system does not relieve you of your per‐

sonal responsibility to assess the visibility con‐

ditions and traffic situation correctly. There is a

risk of accident. Adapt your driving style to the

traffic conditions. Observe the traffic situation

and intervene actively if the situation warrants it.

A Check Control message is displayed in the

event of limited functionality.

Lane Change Warning

Principle

Lane Change Warning detects vehicles in the

blind spot, or if vehicles are approaching from

behind in the adjacent lane. Different levels of

warning are given in these situations.

WARNING

Displays and warnings do not relieve you of

your personal responsibility. System limitations

can mean that warnings or system responses

are not issued or are issued too late, incorrectly

or without justification. There is a risk of acci‐

dent. Adapt your driving style to the traffic con‐

ditions. Observe the traffic situation and inter‐

vene actively if the situation warrants it.

General

Overview

Button in the vehicle

Operational from a minimum speed, two radar

sensors in the rear bumper monitor the area be‐

hind and next to the vehicle.

The minimum speed is country-specific and is

displayed in the menu for the Intelligent Safety

Systems.

The system indicates when vehicles are in the

blind spot, arrow 1, or are approaching from the

rear in an adjacent lane, arrow 2.

WARNING

Warning function

The system may not respond at all, or may re‐

spond too late, incorrectly or without justifica‐

tion due to system limitations. There is a risk of

accident or material damage. Observe the in‐

formation on the system limits and intervene

actively if necessary.

Light in the exterior mirror

Upper speed limit

The system is temporarily disabled at speeds

over approx. 250 km/h, 155 mph.

the system once again responds according to

the setting.

Advance warning

The dimmed light in the exterior mirror indicates

when vehicles are in the blind spot or are ap‐

proaching from the rear.

Functional limitations

The system may have limited functionality in the

following situations, for example:

Acute warning

▷ If the speed of the approaching vehicle is sig‐

nificantly higher than the driver's own speed.

If the turn indicator is activated while a vehicle is

in the critical area, the steering wheel vibrates

briefly and the light in the exterior mirror flashes

brightly.

▷ In thick fog, wet conditions or snow.

▷ On sharp bends or narrow roads.

▷ If the bumper is dirty, iced up or covered,

for example by stickers.

The warning is terminated when the other vehi‐

cle has left the critical area or the turn signal has

been deactivated.

▷ After work performed incorrectly on the vehi‐

cle paintwork.

Flashing of light

▷ When a projecting load is being transported.

A flashing light when the vehicle is unlocked indi‐

cates that the system is performing a self-test.

Attaching any objects, for example stickers or

decals, in the area of the radar beam will also im‐

pair radar sensor operation and may even cause

them to fail.

A Check Control message is displayed in the

event of limited functionality.

The system cannot be switched on when the

trailer socket is in use, for example when operat‐

ing with a trailer or bicycle carrier. A Check Con‐

trol message is shown.

Safety

CONTROLS

Warning displays

WARNING

Depending on the selected setting for warnings,

for example the warning time, it is possible that

more or fewer warnings will be displayed. As a

result, there may also be an increased number of

premature warnings about critical situations.

Displays and warnings do not relieve you of

your personal responsibility. System limitations

can mean that warnings or system responses

are not issued or are issued too late, incorrectly

or without justification. There is a risk of acci‐

dent. Adapt your driving style to the traffic con‐

ditions. Observe the traffic situation and inter‐

vene actively if the situation warrants it.

Rear collision prevention

Principle

The system responds to vehicles approaching

from behind.

Overview

Radar sensors

General

The radar sensors are located in the rear

bumper.

Two radar sensors in the rear bumper monitor

the area behind the vehicle.

Keep the bumpers clean and unobstructed in the

area of the radar sensors.

If a vehicle is approaching from behind at a rele‐

vant speed, the system responds as follows:

▷ The hazard warning lights are switched on to

warn the traffic behind if there is a risk of a

rear collision.

Switching on/off

The system is automatically activated at the start

of each journey.

The system is deactivated in the following situa‐

tions:

Safety notes

▷ When reversing.

WARNING

▷ If the trailer socket is occupied, for example

when operating with a trailer or bicycle carrier.

The system does not relieve you of your per‐

sonal responsibility to assess the visibility con‐

ditions and traffic situation correctly. There is a

risk of accident. Adapt your driving style to the

traffic conditions. Observe the traffic situation

and intervene actively if the situation warrants it.

System limits

The system may have limited functionality in the

following situations:

187

Safety

CONTROLS

▷ If the speed of the approaching vehicle is sig‐

nificantly higher than the driver's own speed.

PostCrash – iBrake

▷ If the approaching vehicle is travelling slowly.

▷ In thick fog, wet conditions or snow.

▷ On sharp bends or narrow roads.

Principle

The system can automatically bring the vehicle

to a standstill in certain accident situations with‐

out the involvement of the driver. The risk of a

further collision and its consequences can

thereby be reduced.

▷ If the bumper is dirty, iced up or covered,

for example by stickers.

▷ If the sensors' field of view is obscured, for

example due to garage walls, hedges or

mounds of snow.

At a standstill

Once the vehicle has come to a halt, the brake is

released automatically.

▷ When a projecting load is being transported.

Dynamic brake lights

Harder vehicle braking

In certain situations, it may be necessary to bring

the vehicle to a standstill more quickly than is

possible with automatic braking.

Principle

The brake lights flash to warn road users behind

the vehicle that an emergency braking manoeu‐

vre is being performed. This can reduce the risk

of a rear-end collision.

To do so, brake quickly and firmly. For a brief pe‐

riod, the braking pressure will be higher than that

achieved with the automatic braking function.

This action interrupts the automatic braking

process.

General

Cancelling automatic braking

In certain situations, it may be necessary to can‐

cel automatic braking, for example for an evasive

manoeuvre.

Cancel automatic braking:

▷ By depressing the brake pedal.

▷ By depressing the accelerator pedal.

▷ Normal braking: brake lights illuminate.

▷ Heavy braking: brake lights flash.

Attentiveness assistant

Shortly before the vehicle comes to a standstill,

the hazard warning lights are activated.

Principle

To switch off the hazard warning lights:

▷ Accelerate.

The system can detect decreasing attentiveness

or the onset of fatigue in the driver on long mo‐

notonous journeys, for example on motorways. In

such situations, the system recommends taking

a break.

▷ Press the hazard warning lights button.

188

Safety

CONTROLS

▷ "Standard": the break recommendation is

given with a defined value.

Safety note

▷ "Sensitive": the break recommendation is

given earlier.

WARNING

The system does not relieve you of your per‐

sonal responsibility to assess your physical

condition correctly. Increasing inattention or fa‐

tigue might not be detected, or may not be de‐

tected in good time. There is a risk of accident.

Make sure that you, as the driver, are rested

and alert. Adapt your driving style to the traffic

conditions.

Display

If the driver shows signs of decreasing attentive‐

ness or of fatigue, a message is shown on the

Control Display with the recommendation to take

a break.

The following settings can be selected during

the display.

After a break, another break recommendation

cannot be displayed until after approximately

45 minutes at the earliest.

Function

The system is switched on every time drive-

ready state is switched on.

System limits

The system may have limited functionality in sit‐

uations such as the following and an incorrect

warning, or no warning at all, may be given:

After commencement of the journey, the system

adapts to the driver so that any decrease in at‐

tention or fatigue can be detected.

This process considers the following criteria:

▷ Personal driving style, for example steering.

▷ If the time is set incorrectly.

▷ When the speed is predominantly below ap‐

prox. 70 km/h, 43 mph.

▷ Driving conditions, for example time of day,

duration of journey.

▷ If a sporty driving style is adopted, for exam‐

ple sharp acceleration or fast cornering.

The system is active from approx. 70 km/h,

43 mph and can also display a recommendation

to take a break.

▷ In active driving situations, for example fre‐

quent lane changes.

Break recommendations

Switching on/off, adjusting

The attentiveness assistant is automatically ac‐

tive every time drive-ready state is switched on

and can thus display break recommendations.

▷ In poor road conditions.

▷ In strong crosswinds.

The system is reset approximately 45 minutes

after the vehicle is stopped, for example when

taking a break during a long motorway journey.

Break recommendations can also be switched

on or off and adjusted via iDrive.

Via iDrive:

1. "My Vehicle"

2. "Vehicle settings"

3. "Attentiveness Assistant"

4. Select the desired setting:

▷ "Off": no break recommendation is given.
