Exterior lamp switch
For safety, smart recommends that you
drive with your low‑beam headlamps on
during the day. In certain countries, local
laws dictate that low‑beam headlamps are
switched on automatically during opera-
tion of the vehicle.
i If you drive in countries where vehi-
cles drive on the other side of the road
than the country in which the vehicle is
registered, you must have the headlamps
modified for symmetrical low beams.
Relevant information can be obtained at
any authorized electric drive smart
center. Exterior lamp switch

Windshield wipers
Switching windshield wipers on and off
Example illustration coupé
X
Make sure the key is in starter switch
position 1.
X Switching on: Turn the wiper switch to
position 0048or0049, depending on the
intensity of the rain.
! Do not operate the windshield wipers
when the windshield is dry. Dust that
accumulates on a windshield might
scratch the glass and/or damage the
wiper blades when wiping occurs on a dry
windshield. If it is necessary to operate
the windshield wipers in dry weather
conditions, always operate the wind-
shield wipers with windshield washer
fluid.
! If anything blocks the windshield wip-
ers (leaves, snow, etc.), switch them off
immediately.
For safety reasons, stop the vehicle in a
safe location and
R -
remove the key from the starter
switch
- engage the parking brake
before attempting to remove any
blockage.
R Remove blockage.
R Turn the windshield wipers on again.
X Switching off: Turn the wiper switch to
position 005A. Intermittent wiping
Only switch on intermittent wiping under
wet weather conditions or in the presence
of precipitation.
Vehicles with rain-light sensor*: When you
select intermittent wiping, the sensor is
activated. The sensor automatically sets a
suitable wiping interval depending on the
wetness of the sensor surface.
! Vehicles with rain-light sensor*:
Do not leave windshield wipers in inter-
mittent setting when the vehicle is taken
to an automatic car wash or during wind-
shield cleaning. Windshield wipers will
operate in the presence of water sprayed
on the windshield, and windshield wip-
ers may be damaged as a result.
! Vehicles with rain-light sensor*:
If you have set intermittent wiping, dirt
on the surface of the sensor or optical
effects may cause the windshield wipers
to wipe in an undesired fashion. This
could then damage the windshield wiper
blades or scratch the windshield. You
should therefore switch off the wind-
shield wipers when weather conditions
are dry.
X Make sure the key is in starter switch
position 1.
X Activating intermittent wiping: Turn the
wiper switch to position 0047.
After the initial wipe, pauses between
wipes are automatically controlled
depending on the vehicle speed and by the
