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.

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)

Warning!
When the recirculation mode is switched
on, windows can fog on the inside immedi

ately. Fogged windows impair visibility,
endangering you and others. If the win

dows begin to fog on the inside, switching
off the air recirculation mode immediate

ly should clear interior window fogging. If
interior window fogging persists, make
sure the air conditioning is switched on,
turn the air distribution control to
positionP (

Warning!
Never drive with iced up or fogged
windows. Visibility will be significantly
impaired. Impaired visibility could en

danger yourself and others. This may
prevent you from observing the traffic
conditions, thereby causing an accident

G
Warning!
To help avoid personal injury during a
collision or sudden maneuver, exercise
care when storing objects in the vehicle.
Put luggage or cargo in the cargo com

partment if possible. Do not pile luggage
or cargo higher than the seat backrests.
Keep compartment lids closed. This will
help to prevent stored objects from
being thrown about and injuring vehicle
occupants during
•braking
•vehicle maneuvers
• an accident
G
Warning!
No racks or loads may be secured to the
roof of the vehicle, as:
• the panorama roof* may be damaged,
thus injuring persons.
• this can have a substantial adverse
effect on the driving dynamics of the
vehicle, thus causing accidents.
• the rack and/or the load could detach
and through this cause an accident or
other people could be injured by the
load and/or rack that has fallen off.
G
Warning!
Make sure the tailgate is closed when the
engine is running and while driving.
Among other dangers, deadly carbon
monoxide (CO) gases may enter vehicle
interior resulting in unconsciousness
and death.

during the break
in period, the more satis

fied you will be with its performance later on.
• Drive your vehicle during the first
1 000 miles (1 500 km) at varying but
moderate vehicle and engine speeds.
• During this period, avoid heavy loads (full
throttle driving) and excessive engine
speeds (no more than
2/3 of maximum rpm in
each gear).
• Shift gears in a timely manner.
• Do not attempt to slow the vehicle down by
shifting to a lower gear.
• Avoid accelerating by kickdown.
After 1 000 miles (1 500 km), you may gradually
increase vehicle and engine speeds to the
permissible maximum.All of the above instructions also apply when
driving the first 1 000 miles (1 500 km) after
the engine has been replaced.

Engine oilThe amount of oil your engine needs will de

pend on a number of factors, including driving
style. Increased oil consumption can occur
when
•the vehicle is new
• the vehicle is driven at higher engine
speeds frequently
Engine oil consumption checks should only be
made after the vehicle break
in period.!
Do not use any special lubricant additives,
as these may increase wear and damage the
drive assemblies. Using special additives not
approved by smart may cause damage not
covered by the smart Limited Warranty.
More information on this subject is available
at any smart center.
G
Warning!
The engine is equipped with a transistor

ized ignition system that utilizes high
voltage. Don not touch any components
