Important safety notes G
WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling these exhaust gases leads to poisoning. There
is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces
without sufficient ventilation.
! Do not depress the accelerator pedal
when starting the engine.
i AMG vehicles: the exhaust flap of the
exhaust system will be checked after every
cold start. Aresulting noise can be heard
during this process.
i During a cold start, the engine runs at
higher speeds to enable the catalytic
converter to reach its operating
temperature. The sound of the engine may
change during this time.
Manual transmission X
Depress the brake pedal and keep it
depressed.
X Fully depress the clutch pedal.
X Shift to neutral N.
i You can only start the engine when the
clutch pedal is fully depressed.
Automatic transmission X
Shift the transmission to position P.
The transmission position display in the
multifunction display shows P.
i You can also start the engine when the
transmission is in position N.
Starting procedure with the SmartKey X
Turn the key to position 3in the ignition
lock (Y page 135)a nd release it as soo nas
the engine is running.

mwarning lamp in the
instrumen tcluster and note any brake status
messages in the multifunction display. For
high-performance driving in particular, it is
important to maintain and have the brake
system checked regularly.
Servicing the brakes !
If the red brake warnin glamp lights up in
the instrumen tcluster and you hear a
warning tone while the engine is running,
the brake fluid level may be too low.
Observe additional warning messages in
the multifunction display.
The brake fluid level may be too low due to
brake pad wear or leaking brake lines.
Have the brake system checked
immediately. This work should be carried
out at a qualified specialist workshop.
! As the ESP ®
system operates
automatically, the engine and the ignition
must be switched off (SmartKey in position
0 or 1in the ignition lock) if the electric
parking brake is being tested on a brake
dynamometer (maximum 10 seconds).
Braking triggered automatically by ESP ®
may seriously damage the brake system.
All checks and maintenance work on the
brake system must be carried out at a
qualified specialist workshop. Have this work
carried out at an authorized Mercedes-Benz
Center.
Have the brake pads replaced and the brake
fluid renewed at a qualified specialist
workshop, e.g. an authorized Mercedes-Benz
Center.
If the brake system has only been subject to
moderate loads, you should tes tthe
functionality of your brakes at regular
intervals. To do so, press firmly on the brake
pedal when driving at a high speed. This
improves the grip of the brake pads.
A description of Brake Assist (BAS):
(Y page 60) Mercedes-Ben
zrecommends that you only
have brake pads/linings installed on your
vehicle which have been approved for
Mercedes-Benzv ehicles or which correspond
to an equivalent quality standard. Brake
pads/linings which have not been approved
for Mercedes-Benzv ehicles or which are not
of an equivalent quality could affect your
vehicle's operating safety.
Mercedes-Benzr ecommends that you only
use brake fluid that has been specially
approved for your vehicle by Mercedes-Benz,
or which corresponds to an equivalent quality
standard. Brake fluid which has not been
approved for Mercedes-Benzv ehicles or
which is not of an equivalent quality could
affect your vehicle's operating safety. Driving on wet roads
Hydroplaning If water has accumulated to a certain depth
on the road surface, there is a danger of
hydroplaning occurring, even if:
R you drive at low speeds.
R the tires have adequate tread depth.
For this reason, in the event of heavy rain or
in conditions in which hydroplaning may
occur, you must drive in the following
manner:
R lower your speed.
R avoid ruts.
R brake carefully.
Driving on flooded roads !
Do not drive through flooded areas.
Check the depth of any water before driving
through it. Drive slowly through standing
water. Otherwise, water may enter the
vehicle interior or the engine compartment.
This can damage the electronic
components in the engin eorthe automatic
transmission. Water can also be drawn in 162

WARNING
When closing the hood, use extreme caution
not to catch hands or fingers. Be careful that
you do not close the hood on anyone.
Make sure the hood is securely engaged
before driving off. Do not continue driving if
the hood can no longer engage after an
accident, for example. The hood could
otherwise come loose while the vehicle is in
motion and injure you and/or others. X
Lower the hood and let it fall from a height
of approximately 8inche s(20cm).
X Check that the hood has engaged properly.
If the hood can be raised slightly, it is not
properly engaged. Open it again and close
it with a little more force. Engine oil
Notes on the oil level Depending on the driving style, the vehicle
consumes up to 0.9 US qt
(0.8l) of oil over a
distance of 600 miles (1000km). The oil
consumption may be highe rthan this when
the vehicle is new or if you frequently drive at
high engine speeds.
AMG vehicles: before operation on race
tracks, check the oil level and (Y page 278)
add oil if necessary (Y page 278). Race track
operation is only permitted with a maximum
engine oil level.
Depending on the engine, the oil dipstick may
be in a different location.
When checking the oil level:
R park the vehicle on a level surface.
R the engine should be switched off for
approximately five minutes if the engine is
at normal operating temperature.
R if the engine is not at normal operating
temperature, e.g. if the engine was only
started briefly: wait about 30 minutes
before carrying out the measurement. Engine compartment
277Maintenance and care Z

Never allow sparks, flames or smoking
materials near gasoline.
Turn off the engine before refueling.
Whenever you are around gasoline, avoid
inhaling fumes and any skin or clothing
contact.
Direct skin contact with fuels and the
inhalation of fuel vapors are damaging to your
health.

Fuel grade
!
Do not use diesel to refuel vehicles with a
gasoline engine. Even small amounts of the
wrong fuel resultind amage to the fuel
system and engine.
! You should only refuel with unleaded
premium-grade gasoline as this avoids
damaging the catalytic converter.
If engine running problem sare apparent,
have the cause checked immediately and
repaired .Excess unburned fuel can
otherwise enter the catalytic converter,
leading to overheating and possibly
causing a fire.
! To ensure the longevity and full
performance of the engine, only premium-
grade unleaded gasoline may be used. If there is no premium-grade unleaded
gasoline available and regular unleaded
gasoline must be used, please observe the
following precautions:
R
only fill the fuel tank to half full with
regular unleaded gasoline and fill the rest
with premium-grade unleaded gasoline
as soo nas possible.
R do not drive at the maximum speed.
R avoid sudden acceleration.
R if the vehicle is carrying a light load, e.g.
two passengers without luggage, do not
allow the engine to rev above 3000 rpm.
R if the vehicle is fully loaded or is being
operated in mountainous terrain, do not
depress the accelerator pedal further
than 0002of the pedal travel.
Only refuel using premium-grade unleaded
gasoline with a minimum octane rating of 91.
Reformulated Gasoline (RFG) and/or
unleaded gasoline with additives can be used.
The concentration of additives in the fuel,
however, must not exceed 10%, e.g.:
R Ethanol
R TAME
R ETBE
R IPA
R TBA
For MTBE, the concentration should not
exceed 15%.
The concentration of methanol in gasoline,
including other additives, must not exceed
3%.
Using mixtures of methanol and ethanol is not
permitted. Gasohol, a mixture of 10% ethanol
and 90% unleaded gasoline, may be used.
All of these mix fuels must fulfill the fuel
requirements, e.g.:
R knock resistance
R boiling point
R vapor pressure
