WARNING
Very hot or very cold air can flow from the air
vents.T his could cause burns or frostbite to
bare skin in the immediate vicinity of the
vents.K eep bare skin away from these air
outlets. If necessary, direct the airflow away
to a different area of the vehicle interior.
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 inlet grille on the bonnet and
in the engine compartment on the front-
passenger side free of blockages, such as
ice, snow or leaves.
R never cover the vents or ventilation grilles
in the vehicle interior.
i You can move the adjuster sfor the air
vents vertically or horizontally, to set the
direction of the airflow.
i Optimal climate control function is ach-
ieved by opening the air vents fully and set-
ting the adjusters to the middle position. 122

Useful information
i This Owner's Manual describes all models
and all standard and optional equipment
available to your vehicle at the time of pub-
lication of the Owner's Manual. Country-
specific deviations are possible. Please
note that your vehicle may not be equipped
with all features described. This also
applies to safety-relevan tsystems and
functions.

WARNING
New brake pads/linings only have optimal
braking performance after several hundred
kilometres .Until then, compensate for this by
applying greate rforce to the brake pedal. This
also applies when brake pads/linings or
brake discs have been changed. The first 1,500 km
If you treat the engine with sufficient care
from the very start,y ou will be rewarded with
excellent performance for the remainder of
the engine's life.
R Drive at varying vehicle speeds and engine
speeds for the first 1,500 km.
R Avoid overstraining the vehicle during this
period, e.g. driving at full throttle.
R Change gear in good time, before the rev
counter needle is Ôof the way to the red
area of the rev counter.
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 point of resistance (kick-
down).
R The shift ranges 3,2or 1should only be
engaged when driving slowly, e.g. when
driving in mountainous terrain.
After 1,500 km, you may gradually bring the
vehicle up to full road and engine speeds.
Additional running-in notes for AMG vehicles:
R do not drive at speeds above 140 km/hf or
the first 1,500 km.
R only allow the engine to reach a maximum
engine speed of 4,500 rpm briefly.
i You should also observe these notes on
running in if the engine or parts of the drive
train on your vehicle have been replaced. AMG vehicles with rear axle locking
differential
Your vehicle is fitted with a self-locking dif-
ferential on the rear axle. Change the oil after
a running-in period of 3,000 km to improve
protection of the rear axle differential. This oil
change extends the service life of the differ-
ential. Have the oil change carried out at a
qualified specialist workshop. Driving
Important safety notes
G
WARNING
Do not place any objects in the driver's foot-
well. If you use a floormat or carpet in the
driver's footwell, make sure that it is correctly
secured and that there is sufficient clearance
for the pedals.
Do not place several floormats on top of one
another.
Loose objects or the floormats could other-
wise get caught between the pedals if you
accelerate or brake suddenly. You will then 126
DrivingDriving and parking

not be able to brake, declutch or accelerate
as intended. This could lead to accidents and
injury. G
WARNING
Do not change down for additional engine
braking on a slippery roa dsurface. This could
cause the drive wheels to lose their grip and
the vehicle could skid. This could cause you
to lose control of your vehicle and cause an
accident.
! Warm up the engine quickly. Do no tuse
the engine's full performance until it has
reached operating temperature.
Only set the automatic transmission to the
respective drive positions when the vehicle
is stationary.
Where possible, avoid spinning the drive
wheels when pulling away on slippery
roads. Otherwise, you could damage the
drive train.
! AMG vehicles: at low engine oil temper-
atures (below +20 †), the maximum
engine speed is restricted in order to pro-
tect the engine. To protect the engine and
maintain smooth engine operation, avoid
driving at full throttle when the engine is
cold. Key positions

KEYLESS-GO General notes
Vehicles with KEYLESS-GO are equipped with
a key featuring an integrated KEYLESS-GO
function and a detachable Start/Stop button.
The Start/Stop button must be inserted into
the ignition lock and the key must be in the
vehicle.
Pressing the Start/Stop button several times
in succession corresponds to the different
key positions in the ignition lock. This is only
the case if you are not depressing the brake
pedal. Driving
