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.

GWARNING
The cooling system is pressurized, particularly
when the motor is warm. If you open the cap,
you could be scalded if hot coolant sprays out.
There is a risk of injury.
Let the engine cool down before you open the
cap. Wear gloves and eye protection. Slowly
open the cap to relieve pressure.
GWARNING
Opening the hood when the engine is over-
heated or when there is a fire in the engine
compartment could expose you to hot gases
or other service products. There is a risk of
injury.
Let an overheated engine cool down before
opening the hood. If there is a fire in the
engine compartment, keep the hood closed
and contact the fire department.
Checking coolant level
Checking the coolant level (example)
XPark the vehicle on a level surface. Only check the coolant level when the vehicle
is on a level surface and the engine has cooled
down.
XTurn the SmartKey to position 2in the igni-
tion lock (Ypage 105).
XCheck the coolant temperature display in the
instrument cluster.
The coolant temperature must be below
158 ‡ (70 †).
XSlowly turn cap :half a turn counter-clock-
wise and allow excess pressure to escape.
XTurn cap :further counter-clockwise and
remove it.
If the coolant is at the level of marker bar =
in the filler neck when cold, there is enough
coolant in coolant expansion tank ;.
If the coolant level is approximately 0.6 in
(1.5 cm) above marker bar =in the filler neck
when warm, there is enough coolant in cool-
ant expansion tank ;.
XIf necessary, add coolant that has been tested
and approved by Mercedes-Benz.
XReplace cap:and turn it clockwise as far as
it will go.
For further information on coolant, see
(

brake fluid reservoir has fallen to the MIN
mark or less, check the brake system imme-
diately for leaks. Also check the thickness of
the brake linings. Visit a qualified specialist
workshop immediately.
Do not add brake fluid. This does not correct
the error.
Only check the brake fluid level when the vehicle
is stationary and on a level surface. The brake
fluid level is correct if the level is between MAX
mark :and MIN mark ;on the brake fluid
reservoir.

also hear a warning tone.
The multifunction display shows a service mes-
sage for several seconds, e.g.:
Service A In 999,999 km
Service A in .. Days
Service A Due
Service A Exceeded 999,999 km
Service A Exceeded .. Days
Maintaining the time-dependent service sched-
ule:
XBefore disconnecting the battery, note down
the service due date displayed.
or
XAfter reconnecting the battery, subtract the
battery disconnection periods from the ser-
vice date shown on the display.
The service interval display should not be con-
fused with the 4engine oil level display.
The symbol and the letter indicate which type of
service is due:
¯ Minor service A
±
Major service B
The ASSYST service interval display does not
take into account any periods of time during
which the battery is disconnected.

The antifreeze/corrosion inhibitor concentra-
tion in the engine cooling system should:
Rbe at least 50%. This will protect the engine
cooling system against freezing down to
approximately -35 ‡ (-37 †).
Rnot exceed 55% (antifreeze protection down
to -49 ‡ [-45 †]). Otherwise, heat will not be
dissipated as effectively.
Mercedes-Benz recommends an antifreeze/
corrosion inhibitor in accordance with MB Spec-
ifications for Service Products 310.1.
iWhen the vehicle is first delivered, it is filled
with a coolant mixture that ensures adequate
antifreeze and anti-corrosion protection.
iThe coolant is checked at specified intervals
at a qualified specialist workshop.
The engine cooling system is filled with coolant
at the factory which contains antifreeze/corro-
sion inhibitor that ensures protection down to
approximately -35 ‡ (-37 †).
