When parking, pay particular attention to
objects above or below the sensors, such
as flower pots or trailer towbars. PARK-
TRONIC does not detect such objects when
they are in the immediate vicinity of the
vehicle. You could damage the vehicle or
the objects.
Ultrasonic sources such as an automatic
car wash, a lorry's compressed-air brakes
or a pneumatic drill could cause PARK-
TRONIC to malfunction.
Minimum distance Centre Approximately 20 cm

indicator lamp goes out and Blind Spot Assist
is operational.
If a vehicle is detected within the monitoring
range of Blind Spot Assist at speeds above
30 km/h, warning lamp :on the corre-
sponding side lights up red. This warning is
always issued when a vehicle enters the blind
spot monitoring range from behind or from
the side. When you overtake a vehicle, the
warning only occurs if the difference in speed
is less than 12 km/h.
The yellow indicator lamp goes out after
reverse gear is engaged. In this event, Blind
Spot Assist is no longer active.
The brightness of the indicator/warning
lamps is adjusted automatically according to
the ambient light. G
Risk of accident
Blind Spot Assist is not active at speeds below
30 km/h, and the indicator lamps in the exte-
rior mirrors are yellow. Vehicles in the moni-
toring range are then not indicated.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to recognise dangers in time, cause an accident
and injure yourself and others.
Collision warning
If a vehicle is detected in the monitoring range
of Blind Spot Assist and you switch on the turn
signal, a double warning tone sounds. Red
warning lamp :flashes. If the turn signal
remains on, detected vehicles are indicated
by the flashing of red warning lamp :. There

tilation* on/off
Notes on the auxiliary heating/ventila-
tion system G
Risk of poisoning
Exhaust fumes are produced when the auxili-
ary heating is in operation. Inhaling these
exhaust fumes can be poisonous. You should
therefore switch off the auxiliary heating in
confined spaces without an extraction sys-
tem, e.g. a garage. G
Risk of fire
When operating the auxiliary heating, parts of
the vehicle may become very hot, and highly
inflammable material such as fuels could be
ignited. Operating the auxiliary heating is thus
prohibited at filling stations or when your vehi-
cle is being refuelled. You must therefore
switch off the auxiliary heating at filling sta-
tions.
i Switch the auxiliary heating on regularly
once a month for about ten minutes.
The auxiliary heating heats the air in the vehi-
cle interior to the set temperature without
using the heat of the running engine. The aux-
iliary heating is operated using the vehicle's
fuel. For this reason, the tank content must
be at least at reserve fuel level to ensure that
the auxiliary heating functions.
The auxiliary heating/ventilation automati-
cally adjusts to changes in temperature and
weather conditions. For this reason, the aux-
iliary heating could switch from ventilation Air conditioning

Running-in notes
The first 1,500 km
G
Risk of accident
New brake pads/linings only have optimal
braking performance after several hundred
kilometres. Until then, compensate for this by
applying greater force to the brake pedal. This
also applies when brake pads/linings or
brake discs have been changed.
If you treat the engine with sufficient care
from the very start, you will be rewarded with
excellent performance for the remainder of
the engine's life.
R Therefore, you should drive at varying road
and engine speeds for the first 1,500 km.
R Avoid heavy loads, e.g. driving at full throt-
tle, during this time. Do not exceed 2
/ 3 of
the maximum permissible engine speed for
each gear.
R Change gear in good time.
R Do not shift down a gear manually in order
to brake.
Vehicles with automatic transmission*:
R try to avoid depressing the accelerator
pedal beyond the pressure point (kick-
down).
R only use ranges 3,2or 1for slow driving,
e.g. in mountainous terrain.
After 1,500 km, you may gradually bring the
vehicle up to full road and engine speeds.
Additional notes on running in AMG vehicles:
R do not drive faster than 140 km/h for the
first 1,500 km.
R only bring the engine up to a maximum
engine speed of 4,500 rpm for a brief
period.
i These running-in instructions must also
be observed if you have the engine, the dif-
ferenial gear or the front axle differential of
your vehicle replaced. AMG vehicles with a rear axle differ-
ential lock*
Your vehicle is equipped with a self-locking
differential on the rear axle. For optimum pro-
tection of the differential gear on the rear
axle, change the oil after running in the vehi-
cle over a distance of 3,000 km. This oil
change will increase the service life of your
differential. Have the oil change performed at
a qualified specialist workshop. Mercedes-
Benz recommends that you use a Mercedes-
Benz Service Centre for this purpose. Refuelling

G
Risk of explosion
Fuel is highly flammable. Fire, naked flames
and smoking are therefore prohibited when
handling fuels.
Switch off the engine and the auxiliary heat-
ing* before refuelling. G
Risk of injury
Do not come into direct contact with fuel.
Direct skin contact with fuels or the inhalation
of fuel vapours is a health hazard. G
Risk of fire
Do not use petrol to refuel vehicles with a die-
sel engine. Never mix diesel with petrol. This
causes damage to the fuel system and engine
and could result in the vehicle catching fire.
! Do not use petrol to refuel vehicles with a
diesel engine. Do not use diesel to refuel
vehicles with a petrol engine. Even small
amounts of the wrong fuel will cause dam-
age to the injection system and engine.
Damage resulting from adding the wrong
fuel is not covered by the warranty.
! Do not start the engine if you accidentally
refuel with the wrong fuel. Otherwise, the
fuel could enter the fuel lines. This would 216

! Refuel using only unleaded, sulphur-free
premium grade petrol with a minimum
octane number of 95 RON/85 MON con-
forming to European standard EN 228.
Otherwise, you could impair engine output
or damage the engine.
i As a temporary measure, only when the
recommended fuel is not available, you
may also use regular unleaded petrol,
91 RON/82.5 MON. This may reduce
engine performance and increase fuel con-
sumption. Avoid driving at full throttle.
In some countries, the fuel grade available
may not be adequate and could cause cok-
ing around the inlet valve. In such cases,
and in consultation with a Mercedes-Benz
Service Centre, the petrol may be mixed
with the additive recommended by
Mercedes-Benz (part no.
A000989254510). You must observe the
notes and mixing ratios specified on the
container.

< 10 ppm) is used for refuelling, the odours
are reduced.
AMG vehicles !
Refuel using only unleaded super grade
petrol with a minimum octane number of
98 RON/88 MON conforming to European
standard EN 228.
Otherwise, you could impair engine output
or damage the engine.
i If the recommended fuel is not available
and only as a temporary measure, you may
also use premium unleaded petrol,
95 RON/85 MON. This may reduce engine
performance and increase fuel consump-
tion. You must avoid driving at full throttle.
! In emergencies, and only when the rec-
ommended fuel is not available, you may
also use standard unleaded petrol,
91 RON/82.5 MON.
However, using this fuel results in consid-
erably higher petrol consumption and sig-
nificantly reduced engine output. Avoid
driving at full throttle.
If no fuel other than regular petrol with
91 RON/82.5 MON or a lower grade is per-
manently available, you should have the
vehicle adapted to run on this fuel by the
local after-sales service. Diesel (EN 590, DIN 51628)
G
Risk of fire
Do not use petrol to refuel vehicles with a die-
sel engine. Never mix diesel with petrol. This
causes damage to the fuel system and engine
and could result in the vehicle catching fire.
! Refuel using only diesel which conforms
to European standard EN 590 or German
standard DIN 51628. Otherwise, you could
impair engine output or damage the engine. !
When refuelling vehicles with a diesel par-
ticulate filter in countries outside the EU,
only low-sulphur Euro diesel with less than
0.005 percent sulphur content by weight
(50 ppm) should be used.
! In countries in which diesel with a higher
sulphur content is available, the engine oil
should be renewed at more frequent inter-
vals. More information about intervals for
changing the engine oil can be obtained
from any Mercedes-Benz Service Centre.
! Using fuel that does not comply with the
European standard EN 590 or the German
standard DIN 51628 can lead to increased
wear, engine damage and damage to the
exhaust system.
Do not use the following:
R marine diesel
R heating oil
R bio-diesel
R vegetable oil
R petrol
R paraffin
R kerosene
Do not add such fuels to diesel fuel and do
not use any special additives (exception:
flow improvers – see "Low outside temper-
atures").
Damage caused by the use of unapproved
fuels or additives is not covered by the
implied warranty.
Further information on "Fuel" (Y page 334).
Low outside temperatures The flow properties of diesel may be inade-
quate at low ambient temperatures.
Diesel fuel with improved cold flow qualities
is available during the winter months. In
Europe, the different climate-dependant cold
categories are defined in standard EN 590.
