156Driving and operatingMaximum speed limiter
In accordance with local or national
regulations, the vehicle may be
equipped with a fixed maximum
speed limiter that cannot be disabled.
If equipped, a warning label indicating the fixed maximum speed limit (90 to
130 km/h) is located on the
instrument panel.
Deviations from the maximum speed
limit may occur briefly when driving
downhill, for physical reasons.
A warning chime will sound for
ten seconds every 40 seconds if the vehicle briefly exceeds the set limit.
Vehicles also equipped with cruise
control speed limiter: the maximum
speed cannot be exceeded by
depressing the accelerator pedal
firmly beyond the point of resistance.
Parking assist
Rear parking assist9 Warning
It is the driver who bears full
responsibility for the parking
manoeuvre.
Always check the surrounding
area while reversing and using the rear parking assist system.
The parking assist measures the
distance between the vehicle and
obstacles behind the vehicle. It
informs and warns the driver by giving acoustic signals and display
indication.
An attached trailer hitch is not
considered.
The system consists of four ultrasonic parking sensors in the rear bumper.
Note
Attached parts in the detection area
cause system malfunction.
Activation
When reverse gear is engaged, the
system switches itself on
automatically. Readiness for
operation is indicated by a brief
acoustic signal.
The interval between the acoustic
signals becomes shorter as the
vehicle gets closer to the obstacle.
When the distance is less than
30 cm, the signal is continuous.
Driving and operating157Note
In versions with Info Display
indication, the volume of the chimes
can be adjusted via the Infotainment system. Refer to Infotainment
manual for further information.
Deactivation
It is possible to permanently or
temporarily deactivate the system.
Note
In versions with Info Display
indication, the function can be
deactivated via the Infotainment
system. Refer to Infotainment
manual for further information.
Temporary deactivation
Temporarily deactivate the system by
pressing r on the instrument panel
with the ignition on. LED illuminates in
the button when deactivated.
When reverse gear is selected, no
acoustic signal will sound, indicating
deactivation.
The function is reactivated by
pressing r again or the next time
the ignition is switched on.
Permanent deactivation
Permanently deactivate the system
by pressing and holding r on the
instrument panel for approx. 3 seconds with the ignition on. LED illuminates continuously in the button
when permanently deactivated.
The system is deactivated and will not
operate. When reverse gear is
selected, no acoustic signal will
sound, indicating deactivation.
The function is reactivated by
pressing and holding r for approx.
3 seconds.Fault
If the system detects an operating fault, when selecting reverse gear a
continuous acoustic alarm will sound
for approx. 5 seconds, a
corresponding message appears in
the Driver Information Centre 3 103
and j illuminates in the instrument
cluster 3 99. Consult a workshop to
have the cause of the fault remedied.Caution
When reversing, the area should
be free from obstacles which could impact on the underside of the
vehicle.
Impact to the rear axle, which may
not be visible, could lead to
uncharacteristic changes in the
vehicle handling. In the event of
such an impact, consult a
workshop.
Vehicle messages 3 104.
Driving and operating159external noise sources may causethe system to fail to detect
obstacles.
Special attention must be paid to low obstacles which can damage
the lower part of the bumper.Caution
Performance of the sensors can
be reduced when sensors are
covered, e.g. by ice or snow.
Performance of the parking assist
system can be reduced due to
heavy loading.
Special conditions apply if there
are taller vehicles involved (e.g.
off-road vehicles, mini vans,
vans). Object identification in the
upper part of these vehicles
cannot be guaranteed.
Objects with a very small reflection
cross-section, e.g. objects of
narrow size or soft materials, may
not be detected by the system.
The parking assist system will not
detect objects which are out of the detection range of the sensors.
Rear view camera
The rear view camera assists the
driver when reversing by displaying a view of the area behind the vehicle in
either the interior mirror or the Info
Display.
9 Warning
The rear view camera does not
replace driver vision. Note that
objects that are outside the
camera's field of view, e.g. below
the bumper or underneath the
vehicle, are not displayed.
Do not reverse the vehicle by only looking at the display and checkthe surrounding area behind and
around the vehicle before
reversing.
The camera is mounted above the
rear doors / tailgate.
The area displayed by the camera is
limited. The distance of the image that
appears on the display differs from
the actual distance.
Note
To achieve the optimum visibility, the rear view camera must not be
obscured by dirt, snow or ice.
160Driving and operatingActivation
Interior mirror display screen
Rear view camera display is
automatically activated when reverse
gear is engaged. An audible signal
confirms activation.
Info Display
In vehicles with Navigation system,
the rear view camera display may be
shown on the Info Display (depending
on version).
Trajectory lane display (1)
Depending on version, the trajectory
lane (1) of the vehicle is shown in blue
on the Info Display. It shows the path of the vehicle in accordance with the
steering angle.
Fixed lane display (2)
The fixed lane display (2) shows the
path of the vehicle if the wheels are
kept straight.
Guide lines (3, 4, 5) are used together
with the fixed lane display (2) and
indicate the distance behind the
vehicle.
Driving and operating163A label with symbols at the fuel filler
flap is indicating the allowed fuel
types. In Europe the pump nozzles of
the filling stations are marked with
these symbols. Refuel only the
allowed fuel type.Caution
In case of misfuelling, do not
switch on ignition.
Note
To ensure the fuel level is displayed
correctly, the ignition must be
switched off before refuelling. Avoid
minor fuel top-ups (e.g. less than
5 l) to ensure accurate readings.
The fuel filler flap is located on the left-
hand side of the vehicle.
The fuel filler flap can only be opened
if the vehicle is unlocked and the left- hand door is opened.
Note
Do not open the left-hand sliding
side door during refuelling.
Pull flap to open.
Caution
In vehicles with AdBlue, the
AdBlue protective cap is the blue
lower cap 3 142 , and the fuel filler
cap is the black upper cap
(arrowed in illustration).
In case of misfuelling, do not
switch on ignition. Seek the
assistance of a workshop
immediately.
To open, turn the cap slowly
anticlockwise.
The fuel filler cap can be retained in
the bracket on the fuel filler flap.
Place the nozzle in straight position to the filler neck and press with slight
force to insert.
To refuel, switch on pump nozzle.
After automatic cut-off, it can be
topped up by operating the pump
nozzle a maximum of two more times.Caution
Wipe off any overflowing fuel
immediately.
When refuelling is complete, replace
the fuel filler cap and turn clockwise
as far as it will go.
Close the fuel filler flap.
Fuel filler cap Only use genuine fuel filler caps.Diesel-engined vehicles have special
fuel filler caps.
170Vehicle careCaution
Do not allow the engine oil level todrop below the minimum level!
We recommend the use of the same
grade of engine oil that was used at
the last change.
Between the MIN and MAX marks a
volume of approx. 2.1 l for engines R9M 408, R9M 413 and R9M 415
respectively approx. 3.5 l for engines
R9M 450 and R9M 452 can be filled
in.
The engine oil level must not exceed the maximum mark MAX on the
dipstick.Caution
Overfilled engine oil must be
drained or suctioned out. If the oil exceeds the maximum level, do
not start the vehicle and contact a
workshop.
To prevent spillage when
replenishing the engine oil, we
recommend using a funnel to top-up the engine oil. Ensure funnel is
securely located onto the filler pipe.
After topping-up, put the funnel into a
plastic bag and stow it securely.
A stabilization of the engine oil
consumption will not take place until
the vehicle has been driven several
thousand kilometres. Only then can
the actual degree of consumption be
established.
If consumption exceeds more than
0.6 l every 1000 km after this running-
in period, consult a workshop.
Fit the cap on straight and tighten it.
Engine air filter
Engine air flow indicator
On certain models, an indicator is
located in the engine induction
system and indicates if the air-intake
to the engine is restricted.
Clear:No restrictionRed tell-tale:Restricted
If the red tell-tale is displayed when
the engine is running, consult a
workshop.
