Warning with braking function
Display
If a collision with a person detected in this way
is imminent, a warning symbol appears on the
instrument cluster and in the Head-up Display.
The red symbol is displayed and a sig‐
nal sounds.
Intervene immediately by braking or make an
evasive maneuver.
Braking intervention
The warning prompts the driver himself/herself
to react. During a warning, the maximum brak‐
ing force is used. Premise for the brake boos‐
ter is sufficiently quick and hard stepping on
the brake pedal. The system can assist with
some braking intervention if there is risk of a
collision. At low speeds vehicles may thus
come to a complete stop.
Manual transmission: During a braking inter‐
vention up to a complete stop, the engine may
be shut down.
The braking intervention is executed only if
DSC Dynamic Stability Control is switched on
and Dynamic Traction Control DTC is acti‐
vated.
The braking intervention can be interrupted by
stepping on the accelerator pedal or by ac‐
tively moving the steering wheel.
Object detection can be restricted. Limitations
of the detection range and functional restric‐
tions are to be considered.System limits
Detection range
The detection potential of the camera is lim‐
ited.
Thus a warning might not be issued or be is‐
sued late.
E. g. the following situations may not be de‐
tected:▷Partially covered pedestrians.▷Pedestrians that are not detected as such
because of the viewing angle or contour.▷Pedestrians outside of the detection range.▷Pedestrians having a body size less than
32 in/80 cm.
Functional limitations
The system may not be fully functional or may
not be available in the following situations:
▷In heavy fog, rain, sprayed water or snow‐
fall.▷In tight curves.▷If the driving stability control systems are
deactivated, e.g. DSC OFF.▷If the camera viewing field or the front
windshield are dirty or covered.▷Up to 10 seconds after the start of the en‐
gine, via the Start/Stop knob.▷During calibration of the camera immedi‐
ately after vehicle shipment.▷If there is constant blinding effects be‐
cause of oncoming light, e. g., from the sun
low in the sky.▷When it is dark outside.

gether.
Hints
Danger of jamming
Before folding down the rear seat back‐
rests, ensure that the area of movement of the
backrests is clear. In particular, ensure that no
one is located in or reaches into the area of
movement of the rear seat backrests when the
middle section is folded down. Otherwise, in‐
jury or damage may result.◀
Ensuring the stability of the child seat
When installing child restraint systems,
make sure that the child seat is securely fas‐
tened to the backrest of the seat. Angle and
headrest of the backrest might need to be ad‐
justed or possibly be removed. Make sure that
all backrests are securely locked. Otherwise the stability of the child seat can be affected,
and there is an increased risk of injury because
of unexpected movement of the seat back‐ rest.◀

However, this has no effect on the perform‐
ance and operational reliability of the brake.
Objects within the range of movement
of the pedals
No objects in the area around the pedals
Keep floor mats, carpets, and any other
objects out of the pedal area; otherwise, the
function of the pedals could be impeded while
driving and create the risk of an accident.
Do not place additional floor mats over existing
mats or other objects.
Only use floor mats that have been approved
for the vehicle and can be properly attached to
floor.
Ensure that the floor mats are securely fas‐
tened again after they were removed for clean‐
ing, e.g.◀
Driving in wet conditions When roads are wet, salted, or in heavy rain,
press brake pedal ever so gently every few
miles.
Ensure that this action does not endanger other traffic.
The heat generated in this process helps dry
the brake discs and pads.
In this way braking efficiency will be available
when you need it.
Hills Avoid stressing the brakes
Avoid placing excessive stress on the
brake system. Light but consistent brake pres‐
sure can lead to high temperatures, brakes
wearing out and possibly even brake failure.◀
Do not drive in neutral
Do not drive in neutral or with the engine
stopped, as doing so disables engine braking.
In addition, steering and brake assist are un‐
available with the engine stopped.◀Drive long or steep downhill gradients in the
gear that requires least braking efforts. Other‐
wise the brakes may overheat and reduce
brake efficiency.
You can increase the engine's braking effect
by shifting down, going all the way to first gear,
if needed.
Brake disc corrosion
Brake disc corrosion and contamination of the
brake pads are favored by:▷Low mileage.▷Extended periods when the vehicle is not
used at all.▷Infrequent use of the brakes.
Corrosion will built up when the maximum
pressure applied to the brake pads during
braking is not reached - thus discs don't get
cleaned.
Corrosion buildup on the brake discs will cause
a pulsating effect on the brakes in their re‐
sponse - generally that cannot be corrected.
Condensation under the parked
vehicle
When using the automatic climate control,
condensation water develops collecting under‐
neath the vehicle.
These traces of water under the vehicle are
normal.
