134Driving and operating9Warning
Smart brake assist may increase
vehicle braking in situations when
it may not be necessary. You
could block the flow of traffic. If this occurs, take your foot off the brakepedal and then apply the brakes
as needed.
Forward collision alert 3 135.
Front pedestrian protection 3 137.
System limitations In some cases, the active emergencybraking system may provide an
automatic braking in situations that
seem to be unnecessary, for instance
in parking garages, due to various
types of objects, i.e., traffic signs or
vehicles in another lane. This is
normal operation, the vehicle does
not need service. Firmly apply the
accelerator pedal to override the
automatic braking if the situation and
the surroundings permit.
In the following cases, active
emergency braking performance
might be limited:
● driving on winding or hilly roads
● detecting vehicles with a trailer, tractors, muddy vehicles, etc.
● detecting a vehicle when weather
limits visibility, such as in fog,
rain, or snow
● driving during nighttime
● the sensor in the windscreen or the radar unit behind the front
bumper are blocked by snow, ice,
slush, mud, dirt etc.
● the windscreen is damaged or affected by foreign objects, e.g.
stickers
the bumper is damaged or
affected by foreign objects, e.g.
license plate support
Complete attention is always required
while driving, and you should be
ready to take action and apply the
brakes and / or steer the vehicle to
avoid crashes.We recommend to deactivate the
system in the vehicle personalisation
in the following cases:
● when towing a trailer or caravan
● when carrying long objects on roof bars or a roof rack
● when the vehicle is being towed with the engine running
● when the vehicle is fitted with snow chains
● when a spare wheel is fitted that is smaller than the other wheels
● before using an automatic car wash with the engine running
● before placing the vehicle on a rolling road in a workshop
● if the windscreen has been damaged close to the camera
● if the front bumper has been damaged
● if the brake lights are not working
Fault
In case the system requires a service,
a message is displayed in the Driver
Information Centre.
Driving and operating141position or if no further obstacles are
detected, no acoustic warning signals
are given.
Deactivation
The system is deactivated
automatically when vehicle speed
exceeds 10 km/h, by applying the
electric parking brake or by pressing
the parking assist button e.
When the system is deactivated
manually, the LED in the button
illuminates.
If the system has been deactivated
manually, it is not reactivated
automatically the next time the
ignition is switched on.
System limitations In the event of a fault or if the system
does not work temporarily, e.g.
because of high external noise level
or other interference factors, C
illuminates in the instrument cluster. A message is displayed in the Driver
Information Centre and a warning
chime sounds.9 Warning
Under certain circumstances,
various reflective surfaces on
objects or clothing as well as
external noise sources may cause the 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 system 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 in the vicinity
(e.g. off-road vehicles, mini vans,
vans). Object identification and correct distance indication 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.
Parking assist systems do not
detect objects outside the
detection range.
Advanced parking assist
9 Warning
The driver bears full responsibility
for accepting the parking slot
suggested by the system and the
parking manoeuvre.
Always check the surrounding
area in all directions when using
the advanced parking assist.
The advanced parking assist
measures a suitable parking slot
while passing, calculates the
trajectory and automatically steers
the vehicle while parking.
162Vehicle careCaution
When transporting the vehicle on
a train or on a recovery vehicle, the
mud flaps might be damaged.
Vehicle storage
Storage for a long period of time
If the vehicle is to be stored for several months:
● Wash and wax the vehicle.
● Have the wax in the engine compartment and underbody
checked.
● Clean and preserve the rubber seals.
● Fill up fuel tank completely.
● Change the engine oil.
● Drain the washer fluid reservoir.
● Check the coolant antifreeze and
corrosion protection.
● Adjust tyre pressure to the value specified for full load.
● Park the vehicle in a dry, wellventilated place. Engage first or
reverse gear or set selector lever
to P. Prevent the vehicle from
rolling.
● Do not apply the parking brake.
● Open the bonnet, close all doors and lock the vehicle.
● Disconnect the clamp from the negative terminal of the vehicle
battery. Note that all systems are
not functional, e.g. anti-theft
alarm system.
Putting back into operation
When the vehicle is to be put back into operation:
● Connect the clamp to the negative terminal of the vehicle
battery. Initialise the power
windows 3 23.
● Check tyre pressure.
● Fill up the washer fluid reservoir.
● Check the engine oil level.
● Check the coolant level.
● Fit the number plate if necessary.End-of-life vehicle recovery
Information on end-of-life vehicle
recovery centres and the recycling of
end-of-life vehicles is available on our website, where legally required. Only
entrust this work to an authorised
recycling centre.
Vehicle care181After adjusting tyre pressure initialise
system to extinguish the control
indicator and restart system.
If the failure continues to be
displayed, contact a workshop. The
system is inoperable when ABS or
ESC has a malfunction or a
temporary spare wheel is used. Once
the tyre has been refitted, check the
tyre pressure with cold tyres and
initialise the system.Caution
Deflation detection system warns
just about low tyre pressure
condition and does not replace
regular tyre maintenance by the
driver.
System initialisation
After tyre pressure correction or
wheel change, the system must be
initialised to learn new circumference
reference values:
1. Always ensure that all four tyres have correct tyre pressure3 210.
2. Apply parking brake. 3. Initialise the system via the Info Display 3 75.
4. Reset is confirmed by pop-up indication.
After 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
Vehicle care183Tyre chains are permitted on tyres of
size 185/65R15 and 195/55R16.
Temporary spare wheel
The use of tyre chains is not permitted on the temporary spare wheel.
Tyre repair kit Minor damage to the tyre tread can be
repaired with the tyre repair kit.
Do not remove foreign bodies from
the tyres.
Tyre damage exceeding 4 mm or that
is at tyre's sidewall cannot be repaired with the tyre repair kit.9 Warning
