Important safety notes
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 heating
before refuelling. G
Risk of injury
Do not come into contact with fuels.
It is hazardous to your health if your skin
comes into direct contact with fuels or you
breathe in fuel vapours. G
Risk of fire
Do not use petrol to refuel vehicles with a die-
sel engine. Do not mix diesel with petrol. This
would result in damage to the fuel system and
engine, which could lead to a vehicle fire.
! Do not use petrol to refuel vehicles with a
diesel engine. Do not use diesel to refuel vehicles with a petrol engine. Even a small
quantity of the wrong fuel will damage the
fuel system and engine.
! Do not switch on the ignition if you acci-
dentally refuel with the wrong fuel. Other-
wise, the fuel will enter the fuel lines. Notify
a qualified specialist workshop and have
the fuel tank and fuel lines drained com-
pletely. Petrol (EN 228)
Fuel grade !
Only refuel using unleaded premium-
grade petrol with at least
95 RON/85 MON, which conforms to Euro-
pean standard EN 228 or an equivalent
specification.
! Do not use the following:
R E85 (petrol with 85 % ethanol)
R E100 (100 % ethanol)
R M15 (petrol with 15 % methanol) 142

Heavy and light loads
G
Risk of accident
Never depress the brake peda lcontinuously
while the vehicle is in motion, e.g. never cause
the brakes to rub by applying constant slight
pedal pressure. This causes the brake system
to overheat, increases the braking distance
and can lead to the brakes failing completely.
If the brakes have been subjected to a heavy
load, do not stop the vehicle immediately, but
drive on for a short while. This allows the air-
flow to cool the brakes more quickly.
If the brakes have been used only moderately,
you should occasionally test their effective-
ness. To do this, brake more firmly from a
higher speed. This improves the grip of the
brakes.
Wet road surface If driving in heavy rain for a prolonged period
of time without braking, there may be a
delayed reaction from the brakes when brak-
ing for the first time. This may also occur after
the vehicle has been washed.
You have to depress the brake pedal more
firmly. Maintain a greater distance from the
vehicle in front.
After driving on a wet road or having the vehi-
cle washed, brake firmly while paying atten-
tion to the traffic conditions. This will warm
up the brake discs, thereby drying them more
quickly and protecting them against corro-
sion.
Limited braking performance on salt
treated roads G
Risk of accident
The layer of salt on the brake discs and the
brake pads/linings may cause a delay in the
braking effect, resulting in a significantly lon-
ger braking distance, which could lead to an
accident.
To avoid this danger, you should: R
occasionally brake carefully, without put-
ting other road users at risk, when you are
driving on salted roads. This helps to
remove any salt that may have started to
build up on the brake discs and the brake
pads/linings.
R maintain a greater distance to the vehicle
ahead and drive with particular care.
R carefully apply the brakes at the end of a
trip and immediately after commencing a
new trip, so that salt residues are removed
from the brake discs.
New brake pads/linings G
Risk of accident
New brake pads/linings only reach their opti-
mum braking effect after several hundred kil-
ometres of driving. Before this optimum brak-
ing effect is reached, you should compensate
for the reduced braking effect by applying
greater pressure when braking. This also
applies after the brake discs or the brake
pads/linings have been replaced.
For safety reasons, Mercedes-Benz recom-
mends that you only have brake pads/linings
fitted to your vehicle which have been
approved for Mercedes-Benz vehicles or
which correspond to an equivalent quality
standard. Brake pads/linings which have not
been approved for Mercedes-Benz vehicles or
which are not of an equivalent quality could
affect your vehicle's operating safety.
High-performance brake system for
AMG vehicles The AMG brake systems are designed for
heavy loads. This may lead to noise when
braking. This will depend on:
R speed
R braking force
R environmental conditions, such as temper-
ature and humidity
The wear of individual components of the
brake system, such as the brake pads/linings 150

Vehicle level Important safety notes
Your vehicle regulates its height automati-
cally. All-round self-levelling ensures the best
possible suspension and constant ground
clearance, even with a laden vehicle. When
you drive fast, the vehicle is lowered auto-
matically to improve driving safety and to
reduce fuel consumption.
The following vehicle levels are possible:
R
normal
R raised: the vehicle is raised by about 25 mm
when compared with the normal level.
R lowered: the vehicle is lowered by about
10 mm when compared with the normal
level.
The "Normal" and "Raised" vehicle levels can
be set manually.
The "Lowered” vehicle level is set automati-
cally:
R at speeds above 140 km/h
R if you have selected "Comfort tuning"
(Y page 168) and then lock the vehicle
within 60 seconds of the engine being
switched off

R there are tears in the sidewalls of the tyre.
After driving in run-flat mode, you must have
the wheel(s) checked for damage at a quali-
fied specialist workshop which has the nec-
essary specialist knowledge and tools to carry
out the wor krequired. The faulty tyre must be
replaced in every case.
Mercedes-Benz recommends that you use a
Mercedes-Benz Service Centre for this pur-
pose. In particular, work relevant to safety or
on safety-related systems must be carried out
at a qualified specialist workshop.
i When replacing one or all tyres, make
sure that you only use tyres marked
MOExtended and of the specified size for
the vehicle.
i Vehicles with MOExtended tyres are not
equipped with a TIREFIT kit at the factory.
It is therefore recommended that you addi-
tionally equip your vehicle with a TIREFIT kit
if you fit tyres that do not feature run-flat
properties, e.g. winter tyres. A TIREFIT kit
can be obtained from a Mercedes-Benz
Service Centre. Battery
Important safety notes
In order for the battery to achieve the maxi-
mum possible service life, it must always be
sufficiently charged.
Have the battery charge checked more fre-
quently if you use the vehicle mainly for short
trips or if you leave it standing idle for a
lengthy period.
To preven tdamage from corrosion, only
replace the battery with one that has a central
ventilation cover.
Only replace a battery with a battery that has
been recommended by Mercedes-Benz. Consult a Mercedes-Ben
zService Centre if
you wish to leave your vehicle parked up for
a long period of time. G
