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.

G
Warning!
High outside temperature, stop
and
go
traffic, driving on long uphill grades or
driving at high engine speed may in

crease the temperature in the engine
compartment. Therefore, the engine
compartment cover and parts in the area
around the engine compartment cover
may be hot. Parts of the engine can be

come very hot. To prevent burns, let the
engine cool off completely before touch

ing the engine compartment cover, parts
in the area around the engine compart

ment cover, and parts of the engine.
G
Warning!
Exercise extreme caution if you see
flames or smoke coming from the engine
compartment. Move away from the vehicle
and call the fire department.
If the coolant temperature warning lamp
indicates that the engine is overheated,
do not attempt to open the engine com

partment cover. Move away from the ve

hicle and wait until the engine has cooled
before opening the engine compartment.G
Warning!
To help prevent personal injury, stay
clear of moving parts when the engine
compartment cover is open and the
engine is running.

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.

Driving instructions
>> Operation
221 Emission control
Certain engine systems serve to keep the
toxic components of the exhaust gases within
permissible legal limits.
These systems, of course, will function prop

erly only when maintained strictly according
to factory specifications.
Any adjustments to the engine should there

fore be carried out only by qualified smart
center authorized technicians.
Engine adjustments should not be altered in
any way. Moreover, the specified service jobs
must be carried out regularly according to
smart servicing requirements. For details
refer to the Maintenance Booklet.
Coolant temperatureDuring severe operating conditions and stop

and
go city traffic, the coolant temperature
may rise close to approximately 248°F
(120°C).
The engine should not be operated with the
coolant temperature over 248°F (120°C).
Doing so may cause serious engine damage
which is not covered by the smart Limited
Warranty.
G
Warning!
Inhalation of exhaust gas is hazardous to
your health. All exhaust gas contains
carbon monoxide (CO), and inhaling it can
cause unconsciousness and lead to death.
Do not run the engine in confined areas
(such as a garage) which are not properly
ventilated. If you think that exhaust gas
fumes are entering the vehicle while
driving, contact a smart center immedi

ately. If you must drive under these con

ditions, drive only with at least one
window fully open at all times.

What to do if ...
>> Practical hints.
241
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.
