Replacing bulbs (vehicles with LED
headlamps)
The front and rear light clusters of your vehicle
are equipped with light-emitting diodes. Do not
replace the vehicle's bulbs yourself. Contact a
qualified specialist workshop which has the nec-
essary specialist knowledge and tools to carry
out the work required.
Lamps are an important aspect of vehicle safety.
You must therefore make sure that these func-
tion correctly at all times. Have the headlamp
setting checked regularly.
Replacing bulbs (vehicles with halo-
gen headlamps)
Important safety notes
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 if it 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
Use bulbs only in closed lamps that have been
designed for this purpose. Only install spare
bulbs of the same type and the specified volt-
age.
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.
Protect bulbs from moisture during operation.
Do not allow bulbs to come into contact with
liquids.
Replace only the bulbs listed (
Ypage 115).
Have the bulbs that you cannot replace yourself
replaced at a qualified specialist workshop.
If you require assistance replacing bulbs, con-
sult a qualified specialist workshop.
If the new bulb still does not light up, consult a
qualified specialist workshop.
Headlamps and lights 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.

Notes on breaking-in a new vehicle
Important safety notes
The sensor system of some driving and driving
safety systems adjusts automatically while a
certain distance is being driven after the vehiclehas been delivered or after repairs. Full system
effectiveness is not reached until the end of this
teach-in procedure.
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 per-
formance 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 gear in good time, before the tach-
ometer needle is Ôof the way to the red area
of the tachometer.
RDo not manually shift to a lower gear to brake
the vehicle.
RTry to avoid depressing the accelerator pedal
beyond the point of resistance (kickdown).
Additional breaking-in notes for Mercedes-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 gear in good time.
RIdeally, for the first 1,000 miles (1,500 km),
drive in the Comfortdrive program.
After 1000 miles (1500 km),you can increase
th eengin espeed gradually and accelerate th e
vehicl eto full speed.
You should also observ ethese note son break-
in g in if th eengin eor part sof th edri ve tra
in on
your vehicl ehav ebeen replaced.
Always observ eth emaximum permissibl e
speed.

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 with-
out sufficient ventilation.
GWARNING
Flammable materials introduced through
environmental influence or by animals can
ignite if in contact with the exhaust system or
parts of the engine that heat up. There is a risk
of fire.
Carry out regular checks to make sure that
there are no flammable foreign materials in
the engine compartment or in the exhaust
system.
