About replacing bulbs
Safe vehicle operation depends on proper
exterior lighting and signaling. It is
therefore essential that all bulbs and lamp
assemblies are in good working order at all
times.
Correct headlamp adjustment is extremely
important. Have headlamps checked and
readjusted at regular intervals and when a
bulb has been replaced. Contact an author-
ized electric drive smart center for head-
lamp adjustment. G
WARNING
Bulbs and bulb sockets can be very hot.
Allow the lamp to cool down before changing
a bulb. Otherwise you could be burned if you
touch them.
Keep bulbs out of the reach of children.
Halogen lamps contain pressurized gas. A
bulb can explode if you:
R touch or move it when hot
R drop the bulb
R scratch the bulb
Wear eye and hand protection.
i If the headlamps or front fog lamps* are
fogged up on the inside as a result of
high humidity, driving the vehicle a
distance with the lights on should clear
up the fogging. Notes on bulb replacement:
R
Only use bulbs of the same type and with
the specified watt rating.
R Switch the lights off before replacing a
bulb to prevent short circuits.
R Always use a clean lint-free cloth when
handling bulbs.
R Your hands should be dry and free of oil
and grease.
R Avoid touching the glass of the bulb with
bare fingers.
R If the newly installed bulb does not come
on, contact an authorized electric drive
smart center.
R Have the bulbs for the front fog lamps*
and the LED daytime running lamps*
replaced at an authorized electric drive
smart center. Replacing bulbs

WARNING
During vehicle operation, the boiling
point of the brake fluid is continuously
reduced through the absorption of moisture
from the atmosphere. Under extremely
strenuous operating conditions, this mois-
ture content can lead to the formation of
bubbles in the system, thus reducing the
system’s efficiency.
Therefore, the brake fluid must be replaced
regularly. Refer to your vehicle’s Mainte-
nance Booklet for replacement interval.
Only brake fluid approved by smart is rec-
ommended. Any authorized electric drive
smart center will provide you with addi-
tional information. Windshield/rear window washer system

WARNING
Windshield washer concentrate is highly
flammable. Fire, naked flames and smoking
are prohibited when windshield washer
concentrate is being handled. Coolants
The battery and drive system coolant is a
mixture of water and anticorrosion/anti-
freeze, which provides:
R Corrosion protection
R Freeze protection
R Boiling protection (by increasing the
boiling point)
The cooling system was filled at the factory
with a coolant providing freeze protection
to approximately -35¦ (-37¥) and cor-
rosion protection.
! Add premixed coolant solution only.
Adding water and MB 325.0 Anticorro-
sion/Antifreeze separately from each
other, could cause drive system damage
not covered by the smart Limited War-
ranty.
If the antifreeze mixture is effective to
-35¦ (-37¥), the boiling point of the
coolant in the pressurized cooling system
is reached at approximately 266¦
(130¥ ).
The coolant solution must be used year
round, even in countries which have high
temperatures to provide the necessary cor-
rosion protection and increase boil‑over
protection. Refer to Maintenance/ Service
Booklet for replacement interval.
Coolant system design and coolant used
determine the replacement interval. The
replacement interval published in the
Maintenance booklet is only applicable if
MB 325.0 Anticorrosion/Antifreeze solu-
tion or other smart approved products of
equal specification are used to renew the coolant concentration or bring it back up
to the proper level.
For information on other smart approved
products of equal specification, contact an
authorized electric drive smart center.
To provide important corrosion protec-
tion, the solution must be at least 50% anti-
corrosion/antifreeze (equivalent to freeze
protection to approximately -35¦
[-37¥]).
If you use a solution that is more than 55%
anticorrosion/antifreeze (freeze protec-
tion to approximately -49
¦[(-45 ¥]), the
drive system and battery temperature will
increase due to the lower heat transfer
capability of the solution. Therefore, do
not use more than this amount of anticor-
rosion/antifreeze.
If the coolant level is low, water and
MB 325.0 Anticorrosion/Antifreeze should
be used to bring it up to the proper level
(have cooling system checked for signs of
leakage). Please make sure the mixture is
in accordance with label instructions.
Always use anticorrosion/antifreeze that
has been approved by smart. For informa-
tion contact an authorized electric drive
smart center.
The water in the cooling system must meet
minimum requirements, which are usually
satisfied by normal drinking water.
If you are not sure about the water quality,
consult an authorized electric drive smart
center.
