Other vehicles changing lane
Distronic has not yet detected the vehicle
cutting in. The distance to this vehicle will be
too short.
Narrow vehicles
Distronic has not yet detected the vehicle in
front on the edge of the carriageway, because
of its narrow width. The distance to the vehi-
cle in front will be too short. Distronic Plus*
i Distronic Plus is not available in all coun-
tries.
Distronic Plus regulates the speed and auto-
matically maintains the distance to the vehi-
cle in front. It brakes automatically in order
to avoid exceeding the set speed. On long and
steep downhill gradients, especially if the
vehicle is laden, you must select shift range
1, 2or 3in good time. By doing so, you will
make use of the braking effect of the engine,
which relieves the load on the brake system and prevents the brakes from overheating
and wearing too quickly. G
Risk of accident
The brake pedal is retracted when Distronic
Plus brakes. Do not restrict the movement of
the pedal in any way.
R Do not put any objects in the footwell.
R Ensure that floor mats and carpets are fixed
securely.
R Do not place your foot under the brake
pedal as it could become trapped.
You could otherwise cause an accident and
injure yourself and others. G
Risk of accident
Do not change down for additional engine
braking on a slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid. G
Risk of accident
Distronic Plus is only an aid designed to assist
driving. The driver remains fully responsible
for the vehicle's distance from other vehicles,
the vehicle's speed and for braking in good
time.
Distronic Plus does not react to:
R pedestrians
R stationary obstacles on the road, e.g. sta-
tionary or parked vehicles
R oncoming and crossing traffic
Distronic Plus may not detect narrow vehicles
driving in front, e.g. motorcycles, or vehicles
driving on a different line. Therefore, always
pay attention to traffic conditions even when
Distronic Plus is activated. Otherwise, you
may fail to recognise dangers in time, could
cause an accident and injure yourself and oth-
ers.
If a slower-moving vehicle is detected in front,
Distronic Plus causes your vehicle to brake
and maintain a preset distance to the vehicle
in front. Driving systems

Distronic Plus may not detect vehicles trav-
elling on a different line. The distance to the
vehicle in front will be too short.
Other vehicles changing lane Distronic Plus has not detected the vehicle
cutting in yet. The distance to this vehicle will
be too short.
Narrow vehicles Distronic Plus does not detect the vehicle in
front on the edge of the carriageway, because
of its narrow width. The distance to the vehi-
cle in front will be too short. Obstructions and stationary vehicles Distronic Plus does not brake for obstacles or
stationary vehicles. For example, if the detec-
ted vehicle turns a corner and reveals an
obstacle or stationary vehicle, Distronic Plus
will not brake for these.
Crossing vehicles Distronic Plus may detect vehicles that are
crossing your lane by mistake. Activating Dis-
tronic Plus at traffic lights with crossing traf-
fic, for example, could cause your vehicle to
pull away unintentionally.
Speedtronic
Speedtronic brakes automatically so that you
do not exceed the set speed. On long and

Risk of accident
The reversing camera is only an aid and may
display obstacles in a distorted or incorrect
manner, or may not even display them at all.
The reversing camera does not relieve you of
the responsibility to pay attention. The cam-
era cannot show objects:
R very near to the rear bumper
R below the rear bumper
R in the area immediately above the boot lid
handle
You are always responsible for safety and
must continue to pay attention to your imme-
diate surroundings when parking and
manoeuvring. This applies to the areas
behind, in front of and next to the vehicle. You
could otherwise endanger yourself and oth-
ers. G
Risk of accident
Under the following circumstances, the
reversing camera will not function, or function
in a limited manner:
R if the boot lid is open
R in heavy rain, snow or fog
R at night or in very dark places
R if the camera is exposed to very bright light
R if the area is lit by fluorescent light (the dis-
play may flicker)
R if there is a sudden change in temperature,
e.g. when driving into a heated garage in
winter
R if the camera lens is dirty or obstructed
R if the rear of your vehicle is damaged. In this
event have the camera position and setting
checked at a qualified specialist workshop.
Mercedes-Benz recommends that you use
a Mercedes-Benz Service Centre for this
purpose.
Do not use the reversing camera in these
types of situation. You could otherwise injure others or damage objects and your vehicle
while you are parking.
Activating the reversing camera X
Make sure that the key is in position 2in
the ignition lock.
X Engage reverse gear.
The area behind the vehicle is shown in the
COMAND display with guide lines. G
Risk of accident
Please note that objects not on ground level
may appear to be further away than they
actually are. These include:
R the bumper of the vehicle parked behind
R trailer tow bars
R the tail-end of a lorry
R slanted posts
The lines are only guides, not accurate meas-
urements of the distance to an obstacle.
Therefore, you should never pass the red line
when approaching an obstacle. You could oth-
erwise cause an accident and injure yourself
and others. Red guide line

For Blind Spot Assist to help you when driving,
the radar sensor system must be switched on
and operational. G
Risk of accident
Blind Spot Assist cannot detect road and traf-
fic conditions.
Blind Spot Assist may not detect narrow vehi-
cles, such as motorcycles or bicycles, or only
detect them too late.
Monitoring may be affected by dirty sensors,
strong spray or poor visibility caused by snow,
rain or mist, for example. In this case, vehicles
are detected late or not at all.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to
recognise dangers in time, could cause an
accident and injure yourself and others.
Monitoring range of the sensors Blind Spot Assist monitors the area up to
three metres behind your vehicle and directly
next to your vehicle as shown in the diagram. G
Risk of accident
Blind Spot Assist monitors certain areas in the
immediate vicinity of your vehicle. Vehicles
that approach and drive past at high speeds are not detected. There is no display and no
warning.
If the lanes are very wide, it may not be pos-
sible to monitor the complete width of the
neighbouring lane. For this reason, vehicles in
the next lane may not be detected, especially
if they are driving in a staggered formation in
different lanes. This may be the case if vehi-
cles are driving at the edge of their lane that
is furthest away from your vehicle.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to
recognise dangers in time, could cause an
accident and injure yourself and others.
If the lanes are narrow, the system may be
unable to distinguish the neighbouring lane
from the one beyond it. For this reason, vehi-
cles in the farther lane may be indicated,
especially if the vehicles are driving in a stag-
gered formation in different lanes. This may
be the case if vehicles are driving at the edge
of the lane that is nearest your vehicle.
The Blind Spot Assist sensors are integrated
into the front and rear bumpers. Make sure
that the bumpers are free from dirt, ice or
slush around the sensors. The radar sensors
must not be covered, for example by cycle
racks or overhanging loads. Following a
severe impact or in the event of damage to
the bumpers, have the function of the radar
sensors checked at a qualified specialist
workshop, e.g. a Mercedes-Benz Service
Centre. Otherwise, Blind Spot Assist may not
work properly. Driving systems

res, tears, bulges on tyres and deformation,
cracks or severe corrosion on wheels), at
least every 14 days, as well as after driving
off-road or on rough roads. Damaged
wheels can cause a loss of tyre pressure.
R Regularly check the tyre tread depth and
the condition of the tread across the whole
width of the tyre (Y page 298). If neces-
sary, turn the front wheels to full lock in
order to inspect the inner side of the tyre
surface.
R All wheels must have a valve cap to protect
the valve against dirt and moisture. Do not
fit anything onto the valve (such as tyre
pressure monitoring systems) other than
the standard valve cap or other valve caps
approved by Mercedes-Benz for your vehi-
cle.
R Regularly check the pressure of all the tyres
including the spare tyre*, particularly prior
to long trips, and correct the pressure as
necessary (Y page 298).
Notes on driving R
While driving, pay attention to vibrations,
noises and unusual handling characteris-
tics, e.g. pulling to one side. This may indi-
cate that the wheels or tyres are damaged.
If you suspect that a tyre is defective,
reduce your speed and stop the vehicle as
soon as possible to check the wheels and
tyres for damage. Hidden tyre damage
could also be causing the unusual handling
characteristics. If you find no signs of dam-
age, have the wheels and tyres examined
at a specialist workshop, for example at a
Mercedes-Benz Service Centre.
R When parking your vehicle, make sure that
the tyres do not get deformed by the kerb
or other obstacles. If it is necessary to drive
over kerbs, speed humps or similar eleva-
tions, try to do so slowly and at an obtuse angle. Otherwise, the tyres, particularly the
sidewalls, can get damaged. Direction of rotation
Tyres with a specified direction of rotation
have additional benefits, e.g. if there is a risk
of aquaplaning. You will only gain these ben-
efits if the correct direction of rotation is
observed.
An arrow on the sidewall of the tyre indicates
its correct direction of rotation.
i You may fit a spare tyre* against the
direction of rotation. MOExtended run-flat system*
The MOExtended run-flat system allows you
to continue driving the vehicle even when one
or more tyres lose all air pressure.
The MOExtended run-flat system may only be
used in conjunction with the tyre pressure
loss warning system or with the tyre pressure
monitor* and on wheels specifically tested by
Mercedes-Benz.
i Vehicles with the MOExtended run-flat
system are not equipped with the TIREFIT
kit. 34
It is therefore recommended to additionally
equip your vehicle with the TIREFIT kit when
fitting tyres that do not feature run-flat
properties, e.g. winter tyres.
i A TIREFIT kit is available from any quali-
fied specialist workshop, e.g. a Mercedes-
Benz Service Centre.
You will find notes on driving with a flat tyre
in the "Practical advice" section
(Y page 381).

Tyre tread
G
Risk of accident
Bear in mind that:
R tyre grip decreases rapidly on wet roads
when the tread depth is less than 3 mm.
Thus, you should replace tyres that have
insufficient tread.
R winter tyres should be replaced when the
tread depth is 4 mm or less as they will no
longer provide adequate grip.
R the tread on a tyre may not wear evenly.
Thus, you should regularly check the tread
depth and the condition of the tread across
the entire width of all tyres. If necessary,
turn the steering wheel so that you can see
the tyre tread more easily.
You could otherwise lose control of the vehi-
cle and cause an accident due to the reduced
grip of the tyres on the road. Tyre pressures
i You will find a table of tyre pressures for
various operating conditions on the inside
of your vehicle's fuel filler flap.
The applicable value for the spare
wheel*/"Minispare" emergency spare
wheel* is stated on the spare wheel and in
the technical data section. G
Risk of accident
Tyre pressure that is either too high or too low
has a negative effect on the vehicle’s driving
safety, which could lead you to cause an acci-
dent. Therefore, you should regularly check
the pressure of all the tyres, particularly prior
to long trips, and correct the pressure as nec-
essary.
To test tyre pressure, use a suitable pressure
gauge. The outer appearance of a tyre does
not permit any reliable conclusion about the
tyre pressure. On vehicles fitted with the elec-
tronic tyre pressure monitor*, the tyre pres- sure can be checked in the on-board com-
puter. G
Risk of accident
Do not fit anything else to the tyre valve other
than the standard valve cap. In particular, ret-
rofitted tyre pressure monitors which are
screwed on to the valve may overload it and
cause it to fail. Due to their design, the valve
is kept open continuously, which may lead to
air loss. G
Risk of accident
Should the tyre pressure drop repeatedly:
R check the tyre for foreign bodies.
R check whether the wheel is losing air or the
valve is leaking.
R make sure that only a valve cap approved
by Mercedes-Benz has been fitted on the
tyre valve.
Tyre pressures that are too low have a nega-
tive effect on vehicle safety, which could lead
to your causing an accident.
If possible, you should only correct tyre pres-
sures when the tyres are cold. Depending on
the ambient temperature, the speed you are
driving at and the load on the tyres, the tyre
temperature and thus the tyre pressure may
change by approximately 0.1 bar per 10 †.
Take this into account when checking the
pressure of warm tyres and only correct it if
it is too low for the current operating condi-
tions.
Driving with tyre pressure that is too high or
too low can:
R shorten the service life of the tyres
R increase the likelihood of tyre damage
R have a negative effect on handling charac-
teristics (e.g. by causing aquaplaning)
i The tyre pressure values given for low
loads are minimum values which offer you
good ride comfort characteristics.
However, you can also use the values given
for higher loads. These are permissible and 298

if the recommended mixture ratio is
observed.
Brake fluid
Over a period of time, the brake fluid absorbs
moisture from the air; this lowers its boiling
point. G
Risk of accident
If the boiling point of the brake fluid is too low,
vapour pockets may form in the brake system
when the brakes are applied hard (e.g. when
driving downhill). This would impair braking
efficiency.
Have the brake fluid renewed every two years
with a brake fluid that has been approved by
Mercedes-Benz and have this confirmed in
the Service Booklet.

compartment to remind you when the next
