WARNING
Very hot or very cold air can flow from the air
vents .This could cause burns or frostbite to
bare skin in the immediate vicinity of the
vents. Keep bare skin away from these air
outlets. If necessary, direct the airflow away
to a different area of the vehicle interior. 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 inlet grille on the bonnet free
of blockages, such as ice, snow or leaves.
R never cover the vents or ventilation grilles
in the vehicle interior.
i For virtually draught-free ventilation,
adjust the sliders of the air vents to the
centre position.
i If the automatic climate control con-
stantly differs from the set temperature or
if undesired draughts are noticeable, pro-
ceed as follows:
XOpen the side air vents
X Open the centre air vents
X Open the rear air vents
X Set the temperature to 22 †.

Useful information
i This Owner's Manual describes all mod-
els, series and optional equipment for your
vehicle that were available at the time of
going to press. Country-specific differen-
ces are possible. Note that your vehicle
may not be fitted with all features descri-
bed. This is also the case for systems and
functions relevant to safety.
i Read the information on qualified special-
ist workshops: (Y page 22). Running-in notes
Important safety notes
New brake pads/brake pads and discs that
have been replaced only achieve optimum
braking effec tafter several hundred kilome-
tres of driving. Compensate for the reduced
braking effect by applying greater force to the
brake pedal. The first 1,500 km
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 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 gea ringood 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.
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/h for
the first 1,500 km.
R Only allow the engine to reach a maximum
engine speed of 4,500 rpm briefly.
R Avoid driving off-road before the differen-
tial oil change at 3,000 km.
R Drive the vehicle mainly in drive program
Cfor the first 1,500 km.
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 differen-
tial lock
To improve the protection of the differential,
change the oil after a run-in distance of
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. 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
R lose its hold function.
There is a risk of fire and an accident. Release
the parking brake fully before driving off.
! Warm up the engine quickly. Do not use
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.

ing feature (Y page 223).
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 starta ssist G
WARNING
After a short time, hill start assist will no lon-
ger 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 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.
