Front airbags

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 hang items of clothing for example

coats or jackets over the backrests.

Protective effect

Airbags are not activated in every collision, for ex‐

ample in minor accidents and rear-end collisions.

▷ 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.

Information for optimum airbag

effectiveness

▷ 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 in some circumstances.

WARNING

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 danger of injury or

even death. Observe the following to achieve

optimum protective effect.

The noise caused by the deployment of an air‐

bag may lead to temporary hearing loss for vehi‐

cle occupants sensitive to noise.

Operational readiness of the

airbag system

▷ Keep your distance from the airbags.

Safety notes

▷ 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.

WARNING

Individual components of the airbag system

may be hot after airbag deployment. There is a

danger of injury. Do not touch individual com‐

ponents.

▷ Make sure that vehicle occupants keep their

head away from the side airbag.

▷ 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.

WARNING

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

jects between the airbags and occupants.

Work carried out incorrectly can lead to a fail‐

ure, a 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 danger of injury or

even death. Have the airbag system tested, re‐

paired or removed and disposed of by a Service

Partner of the manufacturer or another qualified

Service Partner or a specialist workshop.

▷ 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.

▷ Do not glue the airbag covers and do not

cover or modify them in any way.

▷ 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.

Active pedestrian

protection

WARNING

If the system has triggered or is damaged, its

functions will be restricted, or it may no longer

work at all. There is a danger of injury or even

death.

Principle

The active pedestrian protection system raises

the bonnet if the vehicle's front end collides with

a pedestrian. Sensors underneath the bumper

are used for detection. This provides additional

deformation space underneath the bonnet for

the subsequent head impact.

If the system has triggered or is damaged, have

it checked and renewed at a Service Partner of

the manufacturer or another qualified Service

Partner or a specialist workshop.

Safety notes

NOTE

WARNING

Opening the bonnet when the pedestrian pro‐

tection system has triggered may damage the

bonnet or the pedestrian protection system.

There is a risk of material damage. Do not open

the bonnet after the Check Control message is

displayed. Have the system checked by a Serv‐

ice Partner of the manufacturer or another

qualified Service Partner or a specialist work‐

shop.

The system may trigger inadvertently if contact

is made with individual components of the

hinges and bonnet locks. There is a danger of

injury or damage to property. Do not touch indi‐

vidual components of the hinges and bonnet

locks.

WARNING

Modifications to the pedestrian protection sys‐

tem can lead to a failure, a malfunction or acci‐

dental triggering of the pedestrian protection

system. There is a danger of injury or even

death. Do not modify the pedestrian protection

system, its individual components or its wiring.

Do not dismantle the system.

System limits

The active pedestrian protection system is only

triggered at speeds between approx. 20 km/h,

12 mph and 55 km/h, 34 mph.

For safety reasons, the system may also trigger

in rare instances where impact with a pedestrian

shown are current values and may change due to

the effects of driving conditions or weather con‐

ditions.

WARNING

A damaged standard tyre with too little or no

tyre inflation pressure impairs driving character‐

istics, for example steering and braking. Tyres

with run-flat properties allow a limited level of

stability to be maintained. There is a risk of ac‐

cident. Do not continue driving if the vehicle is

Possible driving distance with a deflated

tyre

Run-flat tyres

Safety notes

The possible driving distance varies depending

on the load and stresses the vehicle is subjected

to, for example speed, the nature of the road sur‐

face, outside temperature. The driving distance

may be shorter or, if a more careful driving style

is adopted, may also be longer.

WARNING

A run-flat tyre which has low tyre inflation pres‐

sure or no tyre inflation pressure at all will

change the vehicle's handling characteristics,

for example there may be reduced directional

stability when braking, longer braking distances

and different self-steering characteristics.

There is a risk of accident. Drive with care and

do not exceed a speed of 80 km/h, 50 mph.

If the vehicle is moderately loaded and used un‐

der favourable conditions, it is possible to travel

up to 80 km, 50 miles.

Driving properties with damaged tyres

On a journey with damaged tyres, handling char‐

acteristics change and may result in the following

situations, for example:

WARNING

▷ The vehicle losing traction more quickly.

▷ Longer braking distances.

Continuing to drive with a flat tyre can result in

heavy trailers starting to slalom. There is a dan‐

ger of accidents or damage to property. When

driving with a trailer and a flat tyre, do not ex‐

ceed the speed of 60 km/h, 35 mph. If the

trailer starts to snake, brake immediately and

make the necessary steering corrections as

carefully as possible.

▷ Different self-steering characteristics.

Adapt your driving style. Avoid abrupt steering or

driving over obstacles, for example kerbs or pot‐

holes.

Final tyre failure

Vibration or loud noises during the journey may

be an indication that the tyre has finally failed.

Maximum speed

Reduce your speed and stop the vehicle. Parts of

the tyre could detach, which might lead to an ac‐

cident.

If a tyre is damaged you can continue your jour‐

ney, but do not exceed a maximum speed of

80 km/h, 50 mph.

Do not continue driving, but instead contact a

Service Partner of the manufacturer or another

qualified Service Partner or a specialist work‐

shop.

Continuing a journey with a flat tyre

If you continue a journey with a flat tyre:

1. Avoid heavy braking and sudden steering

manoeuvres.

System limits

Temperature

The tyre inflation pressure depends on the tem‐

perature of the tyre.

2. Do not exceed a speed of 80 km/h, 50 mph.

3. As soon as you get an opportunity, check the

tyre pressure in all four tyres.

If all four tyres are inflated to the correct tyre

inflation pressures, the Tyre Pressure Monitor

might not have been reset. Perform a reset.

The tyre inflation pressure increases as the tyre

temperature increases, for example during driv‐

ing or due to exposure to sunlight.

CONTROLS

Tyre inflation pressure decreases if the tyre tem‐

perature drops.

of the corresponding wheel. The discrepancy will

be detected and reported as a flat tyre.

Through this behaviour, a warning may be trig‐

gered if there are major temperature drops, due

to the given warning limits.

The system does not measure the tyre inflation

pressure as such.

Operating requirements

The following requirements must be met for the

system, otherwise reliable signalling of a loss of

tyre inflation pressure is not ensured:

Sudden loss of tyre inflation

pressure

No warning can be given in the event of extreme,

sudden tyre failure caused by external factors.

▷ After every tyre or wheel change, an initialisa‐

tion must be carried out when the tyre infla‐

tion pressures are correct.

Reset not carried out

The system will not function correctly if a reset

has not been carried out, for example, a flat tyre

is reported in spite of the correct tyre pressure.

▷ An initialisation must be carried out after the

tyre inflation pressure has been adjusted to a

new value.

Malfunction

Status display

The yellow warning lamp flashes and is

then illuminated continuously. A Check

Control message is shown. Tyre pres‐

sure losses may not be detected.

It is possible to display the current status of the

runflat indicator, for example to check whether

the RPA is active.

Initialisation required

▷ Fault due to systems or devices with the

same radio frequency: the system is auto‐

matically reactivated upon leaving the field of

interference.

An initialisation must be performed in the

following situations:

▷ After adjusting the tyre inflation pressure.

▷ After a tyre or wheel change.

Runflat indicator RPA

Initialising

On initialisation, the current tyre pressures are

saved as a reference for detection of a flat tyre.

Initialisation is started by confirming the correct

tyre inflation pressures.

Principle

The system identifies a loss of tyre inflation pres‐

sure by comparing the rotational speeds of the

individual wheels during the journey.

When driving with snow chains fitted, do not initi‐

alise the system.

If a tyre loses inflation pressure, its diameter

changes. This in turn alters the rotational speed

proaching another object at a high differential

speed and there is an immediate risk of a colli‐

sion.

Detection range

The detection ability of the system is limited.

The driver must intervene personally if there is

an acute warning. If necessary, the driver is assis‐

ted by slight automatic brake intervention if there

is a risk of collision.

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:

An acute warning can be triggered even without

a previous advance warning.

▷ Slow-moving vehicle when approaching it at

high speed.

Brake intervention

▷ Vehicles suddenly cutting in or braking heav‐

ily.

The warning prompts the driver to take action.

Maximum braking force is used during a warning.

Braking force support requires the brake pedal to

be pressed sufficiently quickly and firmly. The

system can also assist by applying the brakes

lightly if there is the risk of a collision. At low

speeds, the vehicle can be braked to a stop.

▷ Vehicles with an unusual rear appearance.

▷ Two-wheeled vehicles ahead.

Functional limitations

The system may have limited functionality in the

following situations, for example:

Manual gearbox: when the vehicle is braked to a

stop, the engine may shut off.

▷ In thick fog, wet conditions or snow.

▷ On sharp bends.

The brakes are only applied if driving stability has

not been impaired, for example by deactivation of

Dynamic Stability Control DSC.

▷ When Driving Stability Control Systems are

limited or deactivated, for example DSC OFF.

A brake intervention can be discontinued either

by depressing the accelerator pedal or by ac‐

tively moving the steering wheel.

▷ If, depending on equipment, the field of view

of the camera in the mirror or the radar sen‐

sor is soiled or covered.

Object detection may be limited. Take into ac‐

count the detection range limits and the func‐

tional limitations.

▷ Depending on the vehicle's equipment: after

work performed incorrectly on the vehicle

paintwork.

▷ Up to 10 seconds after starting the engine

using the start/stop button.

System limits

Safety note

▷ During the camera calibration process imme‐

diately after vehicle delivery.

▷ If there is sustained glare due to oncoming

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

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 dan‐

ger of accidents or damage to property.

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.

Safety

CONTROLS

Sensitivity of the warnings

Detection range

The higher the sensitivity of the warning settings,

for example warning time, the more warnings are

displayed. As a result, there may be an increased

number of premature or unjustified warnings and

responses.

Front-end collision warning

with light braking function

Objects detected by the system are taken into

account.

Principle

The system can help avoid accidents. If an acci‐

dent cannot be avoided, the system helps to re‐

duce the collision speed.

Safety notes

The system warns of the possible risk of collision

and brakes automatically, as necessary.

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.

The brakes are applied automatically with limited

braking force for a limited period.

When equipped with Active Cruise Control with

Stop&Go function, the front-end collision warn‐

ing is controlled by the radar sensor of the Cruise

Control.

The front-end collision warning is operational

even if Cruise Control is disabled.

WARNING

When deliberately moving closer to a vehicle, the

front-end collision warning and braking interven‐

tion are activated later to avoid unjustified system

responses.

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

From speeds of approximately 5 km/h, 3 mph,

the system provides a two-stage warning of any

possible risk of collision with vehicles. The timing

of these warnings may vary depending on the

current driving situation.

WARNING

Due to system limitations, individual functions

may not work properly when tow-starting/

towing with activated Intelligent Safety Sys‐

tems. There is a risk of accident. Switch off all

Intelligent Safety Systems before tow-starting/

Detection range

The detection ability of the system is limited.

An acute warning can be triggered even without

a previous advance warning.

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:

Brake intervention

The detection of objects can be influenced by

technical system limitations, e. g. pedestrians or

stationary objects. Limitations of the detection

range and functional limitations are to be consid‐

ered.

▷ Slow-moving vehicle when approaching it at

high speed.

▷ Vehicles suddenly cutting in or braking heav‐

ily.

▷ Vehicles with an unusual rear appearance.

▷ Two-wheeled vehicles ahead.

▷ Pedestrians.

The warning prompts the driver to take action.

Maximum braking force is used during a warning.

Braking force support requires the brake pedal to

be pressed sufficiently quickly and firmly. The

system can also assist by braking the vehicle au‐

tomatically if there is a risk of a collision. The ve‐

hicle can be braked to a stop.

▷ Stationary objects.

Functional limitations

The system may have limited functionality in the

following situations, for example:

Manual gearbox: when the vehicle is braked to a

stop, the engine may shut off.

▷ In thick fog, wet conditions or snow.

▷ On sharp bends.

The brakes are only applied if driving stability has

not been impaired, for example by deactivation of

Dynamic Stability Control DSC.

▷ When Driving Stability Control Systems are

limited or deactivated, for example DSC OFF.

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

the brake intervention takes the form of a brief

jolt. There is no automatic deceleration.

▷ If the radar sensor is soiled or covered.

▷ After work performed incorrectly on the vehi‐

cle paintwork.

A brake intervention can be discontinued either

by depressing the accelerator pedal or by ac‐

tively moving the steering wheel.

Attaching any objects, for example stickers or

Lane Departure Warning

Principle

The Lane Departure Warning issues a warning if

the vehicle leaves its lane on a road with lane

markings.

Detection range

The detection capacity of the camera is limited.

As a result, the system may fail to give warnings

or may give warnings late.

General

For example it is possible that the following may

not be detected:

Depending on the country variant, the system is‐

sues a warning at speeds between 55 km/h,

35 mph and 70 km/h, 45 mph.

▷ Partially concealed pedestrians.

▷ Pedestrians who are not detected as such

due to the viewing angle or outline.

When switching on the system below this speed,

a message is displayed in the instrument cluster.

▷ Pedestrians outside the detection range.

Warnings are issued in the form of steering

wheel vibrations. The timing of this warning may

vary depending on the current driving situation.

▷ Pedestrians less than approximately 80 cm,

32 in tall.

The system does not issue a warning if the driver

indicates before leaving the driving lane.

Functional limitations

The system may have limited functionality or

may not be available at all in the following situa‐

tions, for example:

Safety notes

▷ In thick fog, wet conditions or snow.

▷ On sharp bends.

Manual speed limiter

Principle

The system can be used to set a speed limit so

that speed restrictions are not exceeded.

Operation

Switching on

General

Press the button on the steering wheel.

The system enables speeds from a value of

30 km/h/20 mph and above to be set as a speed

limit. Below the set speed limit, the vehicle can

be driven without restriction.

The current speed is adopted as the speed limit.

When switching on when at a standstill or driving

at low speed, 30 km/h/20 mph is set as the

speed limit.

Exceeding the speed limit

In particular situations the speed limit can be de‐

liberately exceeded by accelerating strongly.

The status display is shown and, depending on

the instrument cluster, a marking in the speed‐

ometer is set to the corresponding speed.

The system gives a warning if the travelling

speed exceeds the set speed limit.

When activating the speed limit it is possible that

Dynamic Stability Control DSC will be switched

on and the drive mode switched to COMFORT.

No brake intervention

Switching off

If the set speed limit has been reached or unin‐

tentionally exceeded, for example when driving

downhill, there is no active brake intervention.

Press the button on the steering wheel.

If you set a speed limit during the journey which

is below the current speed, the vehicle rolls until

the driving speed drops below the speed limit.

The system switches off automatically in the

following situations, for example:

▷ When engaging reverse gear.

▷ When switching the engine off.

▷ When switching on Cruise Control.

▷ When activating some programs using the

Driving Experience Control.

The displays turn off.

Acoustic warning

▷ If you unintentionally exceed the set speed

limit, you will hear an acoustic warning after

approximately 5 seconds.

▷ If the speed limit is reduced to below the

driven speed during the journey, the warning

sounds after approximately 30 seconds.

▷ If you intentionally exceed the speed limit by

fully pressing the accelerator pedal, no warn‐

ing is given.

Press the rocker switch repeatedly up or down

until the desired speed is set.

Marking of the speed limit

▷ Each time the rocker switch is pressed be‐

yond the resistance point, the speed limit is

increased or decreased to the next multiple of

10 km/h/5 mph on the speedometer display.

Display in the speedometer:

▷ Marker illuminates green: the

system is active.

▷ Marker not illuminated: the

system is switched off.

If you set a speed limit while driving which is be‐

low the current speed, the vehicle coasts down

to the set speed limit.

Exceeding the speed limit

You can intentionally exceed the speed limit.

There is no acoustic warning in such a case.

▷ If the indicator lamp is illuminated: the

system is switched on.

▷ If the indicator lamp is flashing: set

speed limit is exceeded.

To exceed the set speed limit intentionally, fully

depress the accelerator pedal.

The limit automatically becomes active again as

Safety

CONTROLS

General

Function

The system is switched on every time the engine

is started and cannot be switched off.

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.

▷ Driving conditions, for example time of day,

duration of journey.

▷ Normal braking: brake lights illuminate.

▷ Heavy braking: brake lights flash.

The system is active from approxi‐

mately 70 km/h, 43 mph and can display a rec‐

ommendation to take a break.

Shortly before the vehicle comes to a standstill,

the hazard warning lights are activated.

To deactivate the hazard warning lights:

▷ Accelerate.

Break recommendations

If the driver shows signs of decreasing attention

or of fatigue, a message is shown on the Control

Display with the recommendation to take a

break.

▷ Press the hazard warning lights button.

A recommendation to take a break will only be

displayed once during an uninterrupted journey.

Attentiveness assistant

After a break, another break recommendation

cannot be displayed until after approximately

45 minutes at the earliest.

Principle

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 you

take a break.

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:

Safety note

▷ If the time is set incorrectly.

▷ When the speed is predominantly below ap‐

prox. 70 km/h, 43 mph.

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.

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

ple sharp acceleration or fast cornering.

▷ In active driving situations, for example fre‐

quent lane changes.

▷ 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.
