If the turn indicator is switched on
while a vehicle is in the critical area,
the steering wheel vibrates briefly
and the light in the exterior mirror
flashes brightly.
The warning is terminated when the
turn signal is cancelled or the other
vehicle has left the critical area.
A flashing light when the vehicle is
unlocked indicates that the system
is performing a self-test.
At speeds over approx. 250 km/h,
155 mph, the system is temporarily
disabled.
At speeds below approx. 250 km/h,
155 mph, the system once again
responds according to the setting.
For further information:
• Radar sensors, see page 50.
The system may have limited func-
tionality in the following situations,
for example:
If the speed of the approaching
vehicle is significantly higher
than the driver's own speed.
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.
After work performed incorrectly
on the vehicle paintwork.
When a projecting load is being
transported.
Attaching any objects – stickers or
film, for example – in the beam
area of the radar sensors will also
restrict the function of the radar
sensors and may even cause them
to fail.
A vehicle message is displayed in
the event of limited functionality.
Depending on the selected setting
for warnings, for example the warn-
ing time, it is po ssible for more
warnings to be displayed. As a
result, there may be an increased

Depending on the equipment and
the nationalmarket version, the
Rear Collision Prevention can

from behind.
Radar sensors monitor the area

If a vehicle is approaching from
behind at a relevant speed, the sys-

PreCrash functions are trig-

The system is controlled using the

The system may ha ve restricted
functionality in the following situa-
tions:
The speed of the approaching
vehicle is much faster than your
own speed.
The approaching vehicle is
approaching slowly.
The brake lights flash to warn road
users behind the vehicle that emer-
gency braking is being performed.
Normal braking: brake lights illu-
minate.
Heavy braking: brake lights flash.
Shortly before the vehicle comes to
a standstill, th e hazard warning
lights are activated.
To switch off the hazard warning
lights:
Accelerate.
Press the hazard warning lights

The system can automatically bring
the vehicle to a standstill in certain
accident situations without the
involvement of the driver. The risk
of a further collision and its conse-
quences can thereby be reduced.
After the vehicle has come to a halt,
the brake is released automatically.
In certain situations, it may be nec-
essary to bring the vehicle to a
standstill more quickly than is pos-
sible with automatic braking.
To do so, brake quickly and firmly.
For a brief period, the braking pres-
sure will be higher than that

In certain situations, it may be nec-

Cancel automatic braking:
By depressing the brake pedal.
By depressing the accelerator

The system can det ect decreasing
attentiveness or the onset of fatigue
in the driver on long monotonous
journeys, for example on motor-
ways. In this situation, it is recom-
mended that you take a break.
The system is switched on every
time drive-ready state is switched
on.
After commencement of the jour-
ney, the system adapts to the driver
so that an decrease in attention or
fatigue can be detected.
This process considers the follow-
ing criteria:
Personal driving style, for exam-
ple, steering.
Driving conditions, for example,
time of day, duration of journey.
The system is active from approx.
70 km/h, 43 mph and can also dis-
play a recommendation to take a
break.
The driver attention control is auto-
matically active every time
drive-ready state is switched on
and can thus display break recom-
mendations.
Break recommendations can also

If the time is set incorrectly.
When the speed is predomi-

In active driving situations, for
example frequent lane changes.
In poor road conditions.
In strong crosswinds.

This chapter describes all standard,
country-specific and special equip-

It may therefore describe equip-
ment and functions which are not
installed in your vehicle, for exam-

ABS prevents the wheels from lock-
ing when the brakes are applied.
Steering control is retained even in
the event of full braking, thereby
enhancing active road safety.
ABS is ready to operate each time
the engine is started.
Situations which the ABS cannot
operate sufficiently:
When entering a curve at an
excessively high rate of speed
In this case, even if the ABS operates,
it cannot operate sufficiently to avoid a
possible dangerous situation. The
driver is solely responsible for under-
standing their surroundings and driving
at a safe speed.
When the brake pedal is depressed
quickly, the system automatically
applies maximum braking power
assistance. By doi ng so, the brak-
ing distance is kept as short as pos-
sible in full braking situations. The
advantages offered by the Anti-lock
Brake System ABS can also be uti-
lised to the full.
The pressure on the brake should
be maintained for the duration of
the full-braking process.
In conjunction with Dynamic radar
cruise control, th is system ensures
that the brake responds even more
quickly when braking in critical situ-
ations.

The system does not relieve you of
your personal responsibility to assess

the traffic conditions. Observe the
traffic situation and intervene actively if the situation warrants it.

When driving with a roof load, for example with a roof rack, the higher
centre of gravity can mean that driv-
ing safety is no longer guaranteed in critical driving situations. There is a
danger of accidents or damage to
property. Do not deactivate Vehicle
