Notes on HVAC
GWarning!
Follow the recommended settings for
heating and cooling given on the following
pages. Otherwise the windows could fog up,
impairing visibility and endangering you
and others.
Air conditioning with climate control*
The air conditioning improves the level of
comfort when driving at high outside
temperatures by cooling and
dehumidifying the air.
Nearly all dust particles, pollutants, are
filtered out by an integrated particle
filter before outside air enters the
passenger compartment through the air
distribution system. It also operates when

temperature warning lamp 00AE in the
instrument cluster indicates that the
coolant is overheated.
R Do not remove the pressure cap on coolant
reservoir if coolant temperature is
above 158 ¦ (70 ¥). Allow engine to cool
down before removing cap. The coolant
reservoir contains hot fluid and is under
pressure.
R Using a rag, slowly turn the cap
approximately 1
/ 2 turn to relieve excess
pressure. If opened immediately,
scalding hot fluid and steam will be
blown out under pressure.
The engine coolant is a mixture of water
and anticorrosion/antifreeze. To check the
coolant level the vehicle must be parked on
level ground and the engine must have
cooled down. For more information, see
“Coolants” ( Y page 209).

Engine oils are specifically tested for
their suitability in our engines and
durability for our service intervals.
Therefore, only use engine oils and oil
filters required for vehicles with the
Maintenance System. For a listing of
approved engine oils and oil filters
contact an authorized smart center.
! Using engine oils and oil filters of
specification other than those expressly
required for the Maintenance System, or
changing of oil and oil filter at change
intervals longer than those called for bythe Maintenance System will result in
engine or emission control system
damage not covered by the smart Limited
Warranty.
Please follow Maintenance System
recommendations for scheduled oil
changes. Failure to do so will result in
engine or emission control system
damage not covered by the smart Limited
Warranty.25 Use a windshield washer concentrate labeled for summer and water for temperatures above freezing

Windshield washer concentrate is highly
flammable. Fire, naked flames and smoking
are prohibited when windshield washer
concentrate is being handled.
Coolants
The engine coolant is a mixture of water
and anticorrosion/antifreeze, 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
corrosion protection.
! Add premixed coolant solution only.
Adding water and MB 325.0
Anticorrosion/Antifreeze separately
from each other, could cause engine
damage not covered by the smart Limited
Warranty.
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
corrosion 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
solution 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 smart center.
To provide important corrosion
protection, the solution must be at least
50% anticorrosion/antifreeze (equivalent
to freeze protection to approximately
-35 ¦ [-37 ¥]).
If you use a solution that is more than 55%
anticorrosion/antifreeze (freeze
protection to approximately -49 ¦
[(-45 ¥]), the engine temperature will
increase due to the lower heat transfer
capability of the solution. Therefore, do
not use more than this amount of
anticorrosion/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
have been approved by smart. For
information contact an authorized 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 smart center.Service fluids and capacities209>> Technical data.451_AKB; 3; 22, en-USd2ureepe,Version: 2.11.8.12009-07-27T09:36:34+02:00 - Seite 209Z

Anticorrosion/antifreeze
Your vehicle contains a number of
aluminum parts. The use of aluminum
components in motor vehicle engines
necessitates that anticorrosion/
antifreeze coolant used in such engines be
specifically formulated to protect the
aluminum parts.
Failure to use such anticorrosion/
antifreeze coolant will result in a
significantly shortened service life.
Therefore, the following product is
strongly recommended for use in your
vehicle: MB 325.0 Anticorrosion/
Antifreeze agent.
Before the start of the winter season (or
once a year in hot southern regions), you
should have the anticorrosion/antifreeze
concentration checked.
The coolant is also regularly checked each
time you bring your vehicle to an
authorized smart center for service.Anticorrosion/antifreeze quantity:ModelApproximate freeze protection-35 ¦ (-37 ¥)-49 ¦ (-45 ¥)Cooling systemAll models2.27 US qt (2.15 l)2.45 US qt (2.32 l)210Service fluids and capacities>> Technical data.
