The Front Assist system technology cannot over-

come the laws of physics and system-related lim-

its. Do not allow the increased convenience Front

Assist can provide tempt you into taking extra

risks. The driver is always responsible for braking

in time. If the Front Assist system issues a warn-

ing, immediately apply the brake to slow the vehi-

cle down or avoid the obstacle, depending on the

traffic situation.

If there are unusual noises during automatic braking

— This is normal and is not a malfunction.

Forward Collision Warning

(Front Assist)

Always adjust your speed and driving style to

road, traffic, weather, and visibility conditions.

Introduction

The Front Assist system cannot prevent acci-

dents and serious injuries on its own.

Depending on vehicle equipment, the vehicle may be

equipped with Forward Collision Warning (Front As-

sist), which can warn the driver of a possible colli-

sion with a vehicle on the road ahead, help prepare

the vehicle for emergency braking, assist with brak-

ing, and initiate automatic braking, within physical

and technical limits of the system. The timing of the

warning varies depending on the traffic situation

and the actions of the driver.

The Front Assist system can issue unnecessary

warnings in certain complex driving situations,

for example, when driving in tight curves.

The Front Assist system can issue unnecessary

warnings when its function is impaired, for ex-

ample, if the radar sensor is dirty or if the posi-

tion of the radar sensor has been changed.

The Front Assist system does not react to ani-

mals.

The Front Assist system is not a substitute for the

driver's full concentration.

The Front Assist system does not react to vehi-

cles crossing your path or approaching in the

same lane.

Driving with Front Assist

You can cancel Front Assist automatic braking inter-

ventions by steering or depressing the accelerator

pedal.

Always be prepared to take full control of the

vehicle at all times.

Automatic braking

WARNING

The Front Assist system can, within system limits,

slow your vehicle down to a standstill, but not keep

your vehicle stopped for a long time. If necessary,

apply the vehicle brakes!

Failure to heed warning lights and instrument

cluster text messages can result in a collision and

serious personal injury.

Never ignore warning lights or text WARNINGS.

During an automatic braking maneuver, the brake

pedal will feel harder.

Please read the introductory information and heed the Warnings and Notice

on page 167.

Fig. 112 In the instrument cluster display: Advance

warning (symbol displayed in color on an instrument

cluster with color display).

Depending on equipment and system limits, Front

Assist can detect the following objects directly in

front of your vehicle:

If you are approaching a detected object at a speed

which will result in a collision and you do not act im-

mediately, Front Assist can help minimize the ef-

fects of a collision. First comes an advanced warn-

ing, then an immediate warning, and finally, an au-

tomatic braking maneuver.

— Pedestrians and vehicles moving in the same di-

rection as your vehicle.

— Pedestrians who are crossing in front of your ve-

hicle.

Advance warning

sary →

in Introduction on page 167.

The system warns the driver with a warning chime

and a message in the instrument cluster display

→ fig. 112 if it detects a possible collision with a ve-

hicle or a pedestrian.

Immediate warning

If you fail to react accordingly to the advance warn-

ing, Front Assist may initiate a short, active braking

maneuver. In this case you will notice brief, jerky

braking of the vehicle to warn you of an impending

collision.

The warning period varies according to the traffic

situation and your driving style.

Brake or take action to avoid the vehicle ahead!

the advance or immediate warnings to reduce vehi-

cle speed and help to minimize the effects of a colli-

sion →

in Introduction on page 167.

Automatic braking

The automatic braking maneuver occurs simultane-

ously with a warning in the instrument cluster dis-

play → fig. 112.

If you should also fail to react to the immediate

warning, Front Assist can initiate an automatic brak-

ing maneuver that will abruptly decelerate the vehi-

cle with increased braking force. The emergency

braking maneuver occurs shortly before a potential

collision to reduce vehicle speed and help to mini-

mize the effects of a collision.

The warning light

comes on.

System deactivated

If the system is switched off, a text message and the

yellow symbol appear in the instrument cluster

display. The yellow central caution light may also

light up.

Braking support

Front Assist can help to minimize the effects of

a collision by providing additional braking force in an

emergency braking situation should the system de-

tect that the force applied to the brake pedal by the

driver is not sufficient to avoid a collision. In order

for Front Assist to provide this additional braking as-

sistance, it must have detected an impending colli-

sion with another vehicle ahead of yours and the

brake pedal has to be hit hard and suddenly. Howev-

er, this support only works as long as the brake ped-

al is depressed.

Distance warning

If the vehicle is traveling within a speed range of

about 40–155 mph (65–250 km/h), the system

warns the driver with the

ment cluster display if it detects that your vehicle is

driving too close to the vehicle ahead → in Intro-

symbol in the instru-

duction on page 167. No acoustic warning will

sound.

Autonomous Emergency Braking

The warning period varies according to the traffic

situation and your driving style.

The Autonomous Emergency Braking system is

a part of Front Assist. In case of an impending colli-

sion, the Autonomous Emergency Braking system

can initiate an automatic braking maneuver without

Increase the distance between your vehicle and the

vehicle ahead.

— When vehicles or motorcycles are traveling slight-

ly offset to the left or right in front of your vehi-

cle.

Front Assist has physical and system-related limits.

You should always be prepared to take full control of

the vehicle whenever necessary.

— When there is oncoming traffic.

— When vehicles are crossing in front of your vehi-

cle.

Delayed response

— When pedestrians are standing or moving toward

you.

If the radar sensor is exposed to environmental con-

ditions that impair sensor function, the system may

detect this only after a certain delay. For this reason,

possible functional restrictions may be displayed on-

ly after a delay after you start driving and while driv-

— When the ASR is manually switched off.

— When the ESC is taking corrective action.

— When the radar sensor is dirty or covered.

If the Front Assist system is switched on

→ page 170, Using Front Assist , then Pedestrian

Monitoring is also active within a speed range of

about 3–40 mph (5–65 km/h).

— When several brake lights on the vehicle are not

working.

— When the vehicle is accelerating quickly.

WARNING

— When the accelerator pedal is completely de-

pressed.

The Pedestrian Monitoring technology cannot

overcome the laws of physics and system-related

limits. Never let the increased convenience provid-

ed by the Pedestrian Monitoring system tempt you

into taking extra risks. The driver is always respon-

sible for braking in time. If the Pedestrian Monitor-

ing system issues a warning, immediately apply

the brakes to slow the vehicle down or avoid the

pedestrian, depending on the traffic situation.

— When the system cannot detect the traffic situa-

tion clearly.

— When there is a fault in the Front Assist system.

When to switch off Front Assist

Front Assist should be switched off in the following

situations due to system limitations →

— If the vehicle is not being driven on public roads,

for example, off-road or on a track.

Always adjust your speed, driving style, and the

distance you keep between you and the vehicles

ahead of you to the road, traffic, weather, and

visibility conditions.

— If the vehicle is being towed.

— If the vehicle is being loaded onto a truck, ferry,

or train.

The Pedestrian Monitoring system cannot pre-

vent accidents and serious injuries on its own.

— If the radar sensor is covered (even temporarily)

by any accessories or other equipment, for exam-

ple, auxiliary headlights.

The Pedestrian Monitoring system can issue un-

necessary warnings in certain complex driving

situations, for example, when driving in tight

curves.

— If the radar sensor malfunctions.

— If an external force has affected the radar sensor,

for example, after a collision.

The Pedestrian Monitoring system can issue un-

necessary warnings or braking maneuvers when

its function is impaired, for example, if the radar

sensor is dirty or if the position of the radar

sensor has been changed.

— If the vehicle is on a dynamometer test bed.

WARNING

The Pedestrian Monitoring system does not re-

act to animals.

Failure to switch off Front Assist in the situations

mentioned can cause accidents and serious per-

sonal injury.

The Pedestrian Monitoring system does not re-

act to pedestrians who are standing still or

moving toward you.

Always be prepared to take full control of the

vehicle at all times.
