Always keep sufficient distance between
unprotected parts of the body and the air
vents. If necessary, use the air distribution
adjustment
to direct the air to air vents in the
vehicle interior that are not in the immediate
area of unprotected skin. General notes
In order to ensure the direct flow of fresh air
through
the air vents into the vehicle interior,
please observe the following notes:
R keep the air intake grill on the hood free of
blockages, such as ice, snow or leaves.
R never cover the air vents or air intake grilles
in the vehicle interior.

Useful information
i This Operator's Manual describes all
models and all standard and optional
equipment of your vehicle available at the
time of publication of the Operator's
Manual. Country-specific differences are
possible.
Please note that your vehicle may
not be equipped with all features
described. This also applies to safety-
related systems and functions.
i Read the information on qualified
specialist workshops: ( Y page 23).Breaking-in notes
Important safety notes
New and replaced brake pads and discs only
reach their optimum braking effect after
several hundred kilometers of driving.
Compensate
for this by applying greater force
to the brake pedal. The first 1,000 miles (1,500 km)
The
more you look after the engine when it is
new, the more satisfied you will be with its
performance in the future.
R You should therefore drive at varying
vehicle and engine speeds for the first
1,000 miles (1,500 km).
R Avoid heavy loads, e.g. driving at full
throttle, during this period.
R Change gear in good time, before the
tachometer needle is Ô of the way to the
red area of the tachometer.
R Do not manually shift to a lower gear to
brake the vehicle.
R If possible, do not depress the accelerator
pedal past the point of resistance
(kickdown).
R Only select shift ranges 3, 2 or 1 when
driving slowly, e.g. in mountainous terrain. After 1,000 miles (1,500 km), you can
increase
the engine speed gradually and bring
the vehicle up to full speed.
Additional breaking-in notes for AMG
vehicles:
R Do not drive faster than 85 mph
(140 km/h for the first 1,000 miles
(1,500 km)
R Only allow the engine to reach a maximum
engine speed of 4,500 rpm briefly.
R Change gear in good time.
R Avoid driving off-road before the
differential oil change at 2,000 miles
(3,000 km).
R Ideally, drive for the first
1,000 miles(1,500 km) in drive program C.
i You should also observe these breaking-
in notes if the engine or parts of the drive
train on your vehicle have been replaced.
i Always observe the respective speed
limits. AMG vehicles with rear axle locking
differential
To improve the protection of the differential,
change the oil after a break-in distance of
2,000 miles (3,000 km). This oil change will
lengthen the service life of the differential.
Have
the oil change carried out at a qualified
specialist workshop. Mercedes-Benz
recommends that you use an authorized
Mercedes-Benz Center for this purpose. Driving

usage of the pedals. G
WARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with
limitations, or not at all. This could affect,
for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk
of an accident.
Do not switch off the ignition while driving. G
WARNING
If the parking brake has not been fully
released
when driving, the parking brake can:
R overheat and cause a fire

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. G
WARNING
Inhalation of exhaust gas is hazardous to your
health. All exhaust gas contains carbon
monoxide (CO), and inhaling it can cause
unconsciousness and possible death.
Do
not run the engine in confined areas (such
as a garage) which are not properly ventilated.
If you think that exhaust gas fumes are
entering the vehicle while driving, have the
cause determined and corrected
immediately. If you must drive under these
conditions, drive only with at least one
window fully open at all times.
! Do not depress the accelerator pedal
when starting the engine. Starting procedure X
Shift the automatic transmission to
position P.
The transmission position display in the
multifunction display shows P.
i For further information about the
automatic transmission, see
(Y page 145).
i If
you depress the brake when starting the
engine, pedal travel is unusually long and
there is less pedal resistance.
X Make sure that the parking brake is
applied.
X Turn the SmartKey in the ignition lock to
position 3 (Y page 139) and release it as
soon as the engine is running.
i You
can also use the touch-start function.
To do this, turn the SmartKey to position 3
(Y page 139) and release it immediately.
The engine then starts automatically. Pulling away

i Upshifts take place at higher engine
speeds after a cold start. This helps the
catalytic converter to reach its operating
temperature more quickly.
Hill start assist G
WARNING
After a short time, hill start assist will no
longer brake your vehicle and it could roll
away.
There is a risk of an accident and injury.
Therefore, quickly move your foot from the
brake pedal to the accelerator pedal. Never
leave the vehicle when it is held by hill start
assist.
Hill start assist helps you when pulling away
forwards or in reverse on an uphill gradient. It holds the vehicle for a short time after you
have
removed your foot from the brake pedal.
This gives you enough time to move your foot
from the brake pedal to the accelerator pedal
and to depress it before the vehicle begins to
roll.
X Take your foot off the brake pedal.
i Once you have taken your foot off the
brake pedal, the vehicle is held for around
one second.
X Pull away.
Hill start assist will not function if:
R you are pulling away on a level road or on
a downhill gradient.
R the transmission is in position N.
