! Shift the transmission into park
position P or reverse gear R only when the
vehicle is stopped in order to avoid
damaging the transmission.
XMake sure the gear selector lever is set
to park position P.
The transmission position indicator
should be on P.XDo not depress the accelerator pedal.XTurn the key to starter switch position

position D.
D appears in the transmission position
indicator.XRelease the brake pedal.XCarefully depress the accelerator pedal.GWarning!
On slippery road surfaces, never downshift
in order to obtain braking action. This
could result in drive wheel slip and
reduced vehicle control. Your vehicle’s ABS
will not prevent this type of loss of control.
GWarning!
It is dangerous to shift the transmission
out of park position P or neutral position
N if the engine speed is higher than idle
speed. If your foot is not firmly on the brake
pedal, the vehicle could accelerate quickly
forward or in reverse. You could lose
control of the vehicle and hit someone or
something. Only shift into gear when the
engine is idling normally and when your
right foot is firmly on the brake pedal.
! Do not run a cold engine at high engine
speeds. Running a cold engine at high
engine speeds may shorten the service
life of the engine.
! Simultaneously depressing the
accelerator pedal and applying the
brakes reduces engine performance and
causes premature brake and drivetrain
wear.
Reversing the vehicle
! Shift the transmission into reverse
gear R only when the vehicle is stopped

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

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
passenger compartment for a short
period of time before utilizing the air
conditioning.

through the air vents can be very hot or very
cold (depending on the set temperature).
This may cause burns or frostbite on
unprotected skin in the immediate area of
the air vents. Always keep sufficient
distance between unprotected parts of the
body and the air vents. If necessary, use the
air distribution control to direct the air
to air vents in the vehicle interior that are
not in the immediate area of unprotected
skin.
To make sure the heating or air
conditioning with climate control* works
properly, please observe the following:
R Keep the air intake grill free from
deposits, e.g. ice or snow, to ensure that
fresh air can flow freely into the vehicle
interior.
R Do not obstruct air vents or ventilation
grilles in the vehicle interior.
i For draft-free ventilation, move the
sliders for the center air vents and side
air vents to the middle position.

Defrosting
GWarning!
Never drive with iced up or fogged
windows. Visibility will be significantly
impaired. Impaired visibility could
endanger yourself and others. This may
prevent you from observing the traffic
conditions, thereby causing an accident.
The best defrosting of windows is achieved
if the ice is completely removed from the
windows manually with an ice scraper
before starting the engine.

Rear window defroster
The rear window defroster serves to de-ice
the rear window quickly and clear the view
if the rear window is fogged.
The rear window defroster uses a large
amount of power. To keep battery drain to a
minimum, switch off the rear window
defroster as soon as the rear window is
clear. The rear window defroster is
automatically deactivated after
approximately 10 minutes of operation.

Air recirculation mode*
Switch to air recirculation mode 13
to
prevent unpleasant odors from entering the
vehicle from the outside (e.g. before
driving through a tunnel). This setting cuts
off the intake of outside air and
recirculates the air in the passenger
compartment.
GWarning!
When the air recirculation mode is
switched on, windows can fog on the inside
immediately. Fogged windows impair
visibility, endangering you and others. If
the windows begin to fog on the inside,
switching off the air recirculation mode
immediately should clear interior window
fogging. If interior window fogging
persists, make sure the air conditioning is
switched on, turn air distribution control

volume using air volume control 0046.

GWarning!
In order to help prevent spilling liquids
on vehicle occupants and/or vehicle
equipment, only use containers that fit
into the cup holder. Use lids on open
containers and do not fill containers to a
height where the contents, especially hot
liquids, could spill during braking,
vehicle maneuvers, or an accident. Liquids
spilled on vehicle occupants may cause
serious personal injury. Liquids spilled
on vehicle equipment may cause damage not
covered by the smart Limited Warranty.
Keep in mind that objects placed in a cup
holder may come loose during braking,
vehicle maneuvers, or an accident and be
thrown around in the vehicle interior.
Objects thrown around in the vehicle
interior may cause an accident and/or
serious personal injury.
The cup holder can be used to safely store
sealed drink bottles, containers with a lid,
or beverage cans.
! Do not use the cup holder as an ashtray.
Otherwise it could be damaged.
