personalisation menu 3 95.
The system includes: ● emergency automatic braking● forward looking brake assist
● forward collision alert
● front pedestrian protection
Emergency automatic braking
After activation of brake preparation
system and just before the imminent
collision, this function automatically
applies limited braking to reduce the
impact speed of the collision or
prohibit a crash. If active emergency
braking is applied, m flashes in the
instrument cluster. Depending on the
situation, the vehicle may
automatically brake moderately or
hard. This front automatic braking can
only occur if a vehicle or a pedestrian
ahead is detected.
Forward collision alert 3 145
Front pedestrian protection 3 149Emergency automatic braking may
slow the vehicle to a complete stop to
try to avoid a potential crash.9 Warning
Emergency automatic braking is
an emergency crash preparation
feature and is not designed to
avoid crashes. Do not rely on the
system to brake the vehicle.
Emergency automatic braking will
not brake outside of its operating speed range and only responds to
detected vehicles and
pedestrians.
Forward looking brake assist
In addition to emergency automatic
braking, the forward looking brake
assist function makes the brake assist more sensitive. Therefore, pressing
the brake pedal less strongly results in immediate hard braking. This
function helps the driver brake
quicker and harder before the
imminent collision.
9 Warning
Active emergency braking is not
designed to apply hard
autonomous braking or to
automatically avoid a collision. It is designed to reduce the vehicle
speed before a collision. It may not
react to animals. After a sudden
lane change, the system needs a
certain time to detect the next
preceding vehicle.
The complete attention of the
driver is always required while
driving. The driver must always be
ready to take action and apply the brakes and steer to avoid
collisions.
The system is designed to work with
all occupants wearing their seat belts.

The lane departure warning systemobserves the lane markings between
which the vehicle is driving via a front camera. The system detects lane
changes and warns the driver in the
event of an unintended lane change
via visual and acoustic signals.
Criteria for the detection of an
unintended lane change are:
● no operation of turn lights
● no brake pedal operation
● no active acceleration
If the driver is active, no warning will
be issued.
Driving and operating165Activation or DeactivationThe system can be activated or
deactivated in the vehicle
personalisation 3 95.
The state of the system stays in
memory when the ignition is switched
off.
Driving time alert
The driver gets notified by a pop-up reminder symbol € in the Driver
Information Centre simultaneously with an acoustic alert if the driver has not taken a break after 2 hours of
driving at a speed above 65 km/h. The
alert is repeated hourly until the
vehicle is stopped, no matter how
vehicle speed evolves.
The counting of driving time alert is
reset when the ignition has been
switched off for a few minutes.
Driver drowsiness detection
The system monitors the driver's level
of vigilance. A camera in the
windscreen detects variations in
trajectory compared to the lanemarkings. This system is particularly
suited for a speed higher than
65 km/h.
If the trajectory of the vehicle
suggests a certain level of
drowsiness or inattention by the
driver, the system triggers the first
level of alert. The driver is notified by
a message and an audible signal is
given.
After three first level alerts, the
system triggers a new alert with a
message, accompanied by a more
pronounced audible signal.
In certain driving conditions (poor
road surface or strong winds), the
system may give alerts independent
of the driver's level of vigilance.
The driver drowsiness detection is
reinitialised when the ignition has
been switched off for a few minutes or the speed remains below 65 km/h for a few minutes.System limitations
The system may not operate properly
when:
● dazzle caused by headlamps of an oncoming vehicles, low sun,
reflections on damp roads
● driving on winding, hilly or narrow
roads
● driving in the dark
● weather limits visibility, such as fog, rain, or snow
● the camera is blocked by snow, ice, slush, mud, dirt
● the windscreen is damaged or affected by foreign items, e.g.

In case of defective LEDs, have them replaced by a workshop.
LED headlights Headlights for low and high beam,
sidelights, daytime running lights and turn lights are designed as LEDs and
cannot be changed.
Have lights repaired by a workshop in
case of failure.
Front fog lights
The bulbs are accessible from the
underside of the vehicle.1. Turn the bulb holder anti- clockwise and remove it from the
reflector housing.
2. Disengage the bulb socket from the plug connector by pressing
the retaining lug.
3. Remove and replace the bulb socket with bulb and attach the
plug connector.
4. Insert the bulb socket into the reflector housing by turning

brake lights are designed as LEDs. In case of defective LEDs, have them
replaced by a workshop.
Light assembly in the body
Detaching the light assembly
1. Unscrew the two screws that secure the light assembly.
198Vehicle careAfter initialisation system
automatically calibrates to new tyre
pressures during driving. After longer
drive the system will adopt and
monitor new pressures.
Always check tyre pressure with cold
tyres.
System has to be reinitialised when: ● tyre pressure has been changed
● load condition has been changed
● wheels have been swapped or exchanged
The system will not warn instantaneously on a tyre blow out or
a rapid deflation. This is due to
required calculation time.
Tread depth
Check tread depth at regular
intervals.
Tyres should be replaced for safety
reasons at a tread depth of 2-3 mm
(4 mm for winter tyres).
For safety reasons, it is
recommended that the tread depth of
the tyres on one axle should not vary
by more than 2 mm.
The legally permissible minimum tread depth (1.6 mm) has been
reached when the tread has worn
down as far as one of the tread wear
indicators (TWI). Their position is
indicated by markings on the
sidewall.
If there is more wear at the front than
the rear, swap round front wheels and rear wheels periodically. If directional tyres are mounted, ensure that thedirection of rotation of the wheels
remains the same.
Tyres age, even if they are not used.
We recommend tyre replacement
every 6 years.
Changing tyre and wheel
size
If tyres of a different size than those
fitted at the factory are used, it may be necessary to reprogramme the tyre
deflation detection system and make
other vehicle modifications.
Tyre deflation detection system
3 197.
Have the label with tyre pressures
replaced.9 Warning
The use of unsuitable tyres or
wheels may lead to accidents and will invalidate the vehicle
operating permit.
Wheel covers
Wheel covers and tyres that are
factory approved for the respective
vehicle and comply with all of the
relevant wheel and tyre combination
requirements must be used.
If the wheel covers and tyres used are
not factory approved, the tyres must
not have a rim protection ridge.
204Vehicle careCaution
The use of a spare wheel that issmaller than the other wheels or in combination with winter tyres
could affect driveability. Have the defective tyre replaced as soon as
possible.
The spare wheel is located in the load
compartment:
1. Open the floor cover.
2. The spare wheel is secured with a
wing nut. Unscrew nut and take
out the spare wheel.
There is a box with tools in the
right wall of the load compartment.
Vehicle tools 3 194.
3. When, after a wheel change, no wheel is placed in the spare wheelwell, fasten the wing nut and close
the floor cover.
4. After a wheel change back to a full
size wheel, place the spare wheel
outside up in the well and secure
with the wing nut.
Temporary spare wheelCaution
If driving with a temporary spare
wheel, active emergency braking
has to deactivated.
Only mount one temporary spare
wheel. The permissible maximum
speed on the label on the temporary
spare wheel is only valid for the
factory-fitted tyre size.
Do not drive faster than 80 km/h. Take
curves slowly. Do not use for a long
period of time.
Fitting the spare wheel
Make the preparations given for
wheel changing 3 202 and observe
the following information:
● Never change more than one wheel at once.
● Use the jack only to change wheels in case of puncture, not
for seasonal winter or summer
tyre change.
● The jack is maintenance-free.
1. Disengage wheel bolt caps with a
screwdriver and remove.
Steel wheels with cover: Pull off
the wheel cover.
Alloy wheels: Disengage wheel
bolt caps with a screwdriver and
remove. To protect the wheel,
place a soft cloth between the
screwdriver and the alloy wheel.
