Important safety notes
Xenon bulbs
GDANGER
Xenonbulbs carry a high voltage. You can get
an electric shock if you remove the cover of
the Xenon bulb and touch the electrical
contacts. There is a risk of fatal injury.
Never touch the parts or the electrical
contacts of the Xenon bulb. Always have work
on the Xenon bulbs carried out at a qualified
specialist workshop.
If your vehicle is equipped with Xenon bulbs,
you can recognize this by the following: the
cone of light from the Xenon bulbs moves
from the top to the bottom and back again
when you start the engine. For this to be
observed, the lights must be switched on
before starting the engine.
Bulbs and lamps are an important aspectof
vehicle safety.You must therefore make sure
that these function correctly at all times.
Have the headlamp setting checked regularly.
Other bulbs
GWARNING
Bulbs, lamps and connectors can get very hot
when operating. If you change a bulb, you
could burn yourself on these components.
There is a risk of injury.
Allow these components to cool down before
changing a bulb.
Do not use a bulb that has been dropped or if
its glass tube has been scratched.
The bulb may explode if:
Ryou touch it
Rit is hot
Ryou drop it
Ryou scratch it
Only operate bulbs in enclosed lamps
designed for that purpose. Only install spare
bulbs of the same type and the specified
voltage.
Marks on the glass tube reduce the service
life of the bulbs. Do not touch the glass tube
with your bare hands. If necessary, clean the
glass tube when cold with alcohol or spirit and
rub it off with a lint-free cloth.
Protectbulbs from moisture during
operation.Do not allow bulbs to come into
contact with liquids.
There are bulbs other than the Xenon bulbs
that you cannot replace. Replace only the
bulbs listed (Ypage 111). Have the bulbs that
you cannot replace yourself changed at a
qualified specialist workshop.
If you require assistance changing bulbs,
consult a qualified specialist workshop.
If the new bulb still does not light up, consult
a qualified specialist workshop.
Bulbs and lamps are an important aspect of
vehicle safety. You must therefore make sure
that these function correctly at all times.
Have the headlamp setting checked regularly.

Setting climate control to automatic
Points to observe before use
The automatic function is only available in
conjunction with dual-zone automatic climate
control.
In automatic mode, the set temperature is
maintained automatically at a constant level.
The system automatically regulates the
temperature of the dispensed air, the airflow
and the air distribution.
The automatic mode functions optimally
when the "Cooling with air dehumidification"
function is activated. If necessary, cooling
with air dehumidification can be deactivated.
If you deactivate the "Cooling with air-
dehumidification" function, the air inside the
vehicle will not be cooled. The air inside the
vehicle will also not be dehumidified. The
windows can fog up more quickly. Therefore,
only deactivate the "Cooling with air-
dehumidification" function briefly.

Notes on breaking-inanew vehicle
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 1000 miles (1500 km)
The more you look after the engine when it is
new, the more satisfied you will be with its
performance in the future.
RYou should therefore drive at varying
vehicle and engine speeds for the first
1000 miles (1500 km).
RAvoid heavy loads, e.g.driving at full
throttle, during this period.
RChange gearingood time, before the
tachometer needle is
of the way to the
red area of the tachometer.
RDo not manually shift to a lower gear to
brake the vehicle.
RIf possible, do not depress the accelerator
pedal past the point of resistance
(kickdown).
RIdeally, for the first 1000 miles(1500 km),
drive in programE.
After 1,000 miles (1,500 km), you can
increase the engine speed gradually and bring
the vehicle to full speed.
Additional breaking-in notes for AMG
vehicles:
RDo not drive faster than 85 mph
(140 km/h) for the first 1,000 miles
(1,500 km).
ROnly allow the engine to reach a maximum
engine speed of 4,500 rpm briefly.
RChange gearingood time.
iYou should also observe these notes on
breaking-in if the engine or parts of the
drive train on your vehicle have been
replaced.
iAlways observe the respective speed
limits.
Driving
Important safety notes
GWARNING
Objects in the driver's footwell can restrictthe
pedal travel or obstructadepressed pedal.
The operating and road safety of the vehicle
is jeopardized. There is a risk of an accident.
Make sure that all objects in the vehicle are
stowed correctly, and that they cannot enter
the driver's footwell. Install the floormats
securely and as specified in order to ensure
sufficientclearance for the pedals. Do not use
loose floormats and do not place floormats on
top of one another.
GWARNING
Unsuitable footwear can hindercorrect usage
of the pedals, e.g.:
Rshoes with thick soles
Rshoes with high heels
Rslippers
There is a risk of an accident.
Wear suitable footwear to ensure correct
usage of the pedals.
136Driving
Driving and parking

the engine compartment or in the exhaust
system.
!Do not depress the accelerator pedal
when starting the engine.
iDuring a cold start, the engine runs at
higherspeeds to enable the catalytic
converter to reach its operating
temperature. The sound of the engine may
change during this time.
Automatic transmission
XShift the transmission to positionP.
Transmission position displayPis shown in
the multifunction display.
iWhen the transmission is in positionN,
you can also start the engine with the brake
pedal depressed.
Starting procedure
XTurn the SmartKey to position3in the
ignition lock (Ypage 137)and release it as
soonas the engine is running.
Pulling away
Automatic transmission
iIt is only possible to shift the transmission
from positionPto the desired position if
you depress the brake pedal.Only then can
the parking lock be deactivated.Ifyou do
not depress the brake pedal, the DIRECT
SELECT lever can still be moved but the
parking lock remains engaged.
iIf the transmission oil temperature is
below4‡(20†), you can only shift from
positionPwhen the engine is running.
XDepress the brake pedal and keep it
depressed.
XShiftthe transmission to positionDorR.
XRelease the brake pedal.
XCarefully depress the accelerator pedal.
The electric parking brake (Ypage 154) is
automatically released.
The red indicator lamp in the
instrumentcluster goes out.
iThe vehicle locks centrally once you have
pulled away. The locking knobs in the doors
drop down.
You can open the doors fromthe inside at
any time.
You can also deactivate the automatic
locking feature (Ypage 208).
iUpshifts take place at higher engine
speeds after a cold start. This helps the
catalytic converter to reach its operating
temperature more quickly.
Hill startassist
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.
GWARNING
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.
XRemove your foot from the brake pedal.
The vehicle is then held for about a second.
XPull away.
Hill start assist is not active if:
Ryou are pulling away on a level road or on
a downhill gradient.
Rthe transmission is in positionN.

lower gear depending on the engine speed.
XEase off the accelerator pedal once the
desired speed is reached.
The automatic transmission shifts back up.
Rocking the vehicle free
Shifting the transmission repeatedly between
gearsDandRmay help to free the vehicle if
it has become stuck in slush or snow. The
