Air conditioning with climate control*
>> Controls.
151
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 com

partment through the air distribution system.
It also operates when the air conditioning is
switched off and you have switched on the
blower.
The air conditioning only works when the
engine is running and the blower is switched
on. Maximum effectiveness is achieved if you
drive with the windows closed.
i
In warmer weather, ventilate the passen

ger compartment for a short period of time
before utilizing the air conditioning.
Switching air conditioning on/off>Make sure that the engine is running.
>Switching on: Push air volume control
1 to
level1 or higher.
>Press switch
2.
The air conditioning is switched on.
The indicator lamp on the switch comes on.
>Switching off: Press switch
2 once more.
The air conditioning is switched off.
The indicator lamp on the switch goes out.
i
The stored status is restored, if you switch
on the ignition again.
i
The air condition will be suspended tem

porarily:
• if the engine speed is too low
•when driving off
The air condition is switched off:
• at a coolant temperature of more
than 239°F (115°C)
• at outside temperatures below 38°F (3°C)
G
Warning!
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.

Coolant
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" (

page 309).Checking coolant level
The coolant reservoir is located in the front
compartment on the driver’s side.

G
Warning!
In order to avoid potentially serious
burns:
• Use extreme caution when opening the
service flap if there are any signs of
steam or coolant leaking from the
cooling system, or if the coolant
temperature warning lampD in the
instrument cluster indicates that the
coolant is overheated.
• Do not remove pressure cap on coolant
reservoir if coolant temperature is
above 158°F (70°C). Allow engine to
cool down before removing cap. The
coolant reservoir contains hot fluid
and is under pressure.
• Using a rag, slowly open the cap ap

proximately
1/2 turn to relieve excess
pressure. If opened immediately,
scalding hot fluid and steam will be
blown out under pressure.

and remove it.
The coolant level is correct if the level
• for cold coolant: reaches marking bar

visible through the filling opening
• for warm coolant: is approximately 0.6 in
(1.5 cm) higher
>If necessary, add coolant.

washer reservoir.
The recommended minimum filling level is

The windshield washer reservoir is located in
the front compartment on the driver’s side.

CapDuring all seasons,
• use a windshield washer concentrate la

beled for summer and water for tempera

tures above freezing point.
• use a windshield washer concentrate la

beled for winter and water for tempera

tures below freezing point.

Windshield washer concentrate is highly
flammable. Fire, naked flames and
smoking are prohibited when windshield
washer concentrate is being handled.

Coolant temperature warning lamp
Illuminates:
• when the ignition is switched on.
The warning lamp goes out if the engine is
running.
• if the coolant is too hot.
>Stop the vehicle immediately in a safe
location.
>Do not continue to drive.
>Turn off the engine.
>Set the parking brake when leaving the
vehicle.
>Contact Roadside Assistance or an autho

rized smart center.If the coolant level has fallen below the
marking bar on the coolant reservoir
(

page 178):
>Add coolant as required.
>Have the coolant system checked for leaks
at an authorized smart center.
!
Among other possible causes, the
poly
V
belt could be broken. Do not continue
to drive. Otherwise, the engine will overheat
due to an inoperative water pump which may
result in damage to the engine.
When the system detects a malfunction,
the telltale will flash for approximately
1 minute and then remain continuously
illuminated.
This sequence will continue upon subse

quent vehicle start
ups as long as the
malfunction exists. When the malfunction
indicator is illuminated, the system may
not be able to detect or signal low tire
pressure as intended.
TPMS malfunctions may occur for a vari

ety of reasons, including the installation
of incompatible replacement or alternate
tires or wheels on the vehicle that pre

vent the TPMS from functioning properly.
Always check the TPMS malfunction tell

tale after replacing one or more tires or
wheels on your vehicle to ensure that the
replacement or alternate tires and
wheels allow the TPMS to continue to
function properly.
G
Warning!
Driving when your engine is overheated
can cause some fluids, which may have
leaked into the engine compartment, to
catch fire. You could be seriously burned.
Turn off the engine, get out of the vehicle
and do not stand near the vehicle until
the engine has cooled down.

309 Coolants
The engine coolant is a mixture of water and
anticorrosion/antifreeze, which provides:
• Corrosion protection
• Freeze protection
• Boiling protection (by increasing the
boiling point)
The cooling system was filled at the factory
with a coolant providing freeze protection to
approximately
35°F (
37°C) and corrosion
protection.!
Add premixed coolant solution only.
Adding water and MB 325.0 Anticorrosion/An

tifreeze separately from each other, could
cause engine damage not covered by the
smart Limited Warranty.
If the antifreeze mixture is effective to
35°F
(
37°C), the boiling point of the coolant in the
pressurized cooling system is reached at
approximately 266°F (130°C).The coolant solution must be used year round,
even in countries which have high tempera

tures to provide the necessary corrosion
protection and increase boiling protection.
Refer to Maintenance/ Service Booklet for re

placement interval.
Coolant system design and coolant used
determine the replacement interval. The
replacement interval published in the Mainte

nance booklet is only applicable if MB 325.0
Anticorrosion/Antifreeze solution or other
smart approved products of equal specifica

tion are used to renew the coolant concentra

tion 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% anticorro

sion/antifreeze (equivalent to freeze protec

tion to approximately
35°F [
37°C]).If you use a solution that is more than 55%
anticorrosion/antifreeze (freeze protection
to approximately
49°F [
45°C]), 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.
