windshield wipers depending on how wet
the windshield is.

(page 47).
After the initial wipe, pauses between
wipes are automatically controlled by the
rain sensor which monitors the wetness of
the windshield.

Switch on ignition.

Press switch1.
iIntermittent wiping is interrupted when
the vehicle is at a standstill and a front
door is opened.
!To prevent the windshield wipers from
being damaged, do not leave the wiper
switch in intermittent setting when tak-
ing the vehicle to an automatic car
wash or when cleaning the windshield.
The switch should not be left in inter-
mittent setting as the wipers will wipe
the windshield once every time the en-
gine is started. Dust that accumulates
on the windshield might scratch the
glass when wiping occurs on a dry
windshield.iIf intermittent wiping is on and you turn
the SmartKey in the steering lock from
position 1 to position 2 (
page 31)
and keep the SmartKey in that position
longer than 2 seconds, the wipe inter-
val will be set to approximately 5 sec-
onds.

176 Controls in detailAutomatic climate controlThe automatic climate control is operation-
al whenever the engine is running. You can
operate the climate control system in ei-
ther the automatic or manual mode. The
system cools or heats the interior depend-
ing on the selected interior temperature
and the current outside temperature.Nearly all dust particles, pollutants and
odors are filtered out before outside air en-
ters the passenger compartment through
the air distribution system.
The air conditioning will not engage (no
cooling) if the economy mode AC
OFF
is se-
lected (
page 184).
Warning!
G
When operating the automatic climate con-
trol, the air that enters the passenger com-
partment through the air vents in the
footwell can be very hot or very cold (de-
pending on the set temperature). This may
cause burn or frostbite to unprotected skin
in the immediate area of the air vents. Al-
ways keep sufficient distance between un-
protected parts of the body and the footwell
air vents. If necessary change the air flow
using the air distribution controls to direct
the air away from the footwell air vents
(page 178).
Warning!
G
Follow the recommended settings for heat-
ing and cooling given on the following pag-
es. Otherwise the windows could fog up,
impairing visibility and endangering you and
others.
iThe current climate control settings
(ON/OFF, temperature, air volume, ac-
tivated charcoal filter, etc.) are stored
for each SmartKey before it is removed
from the starter switch or when the ve-
hicle is locked using the KEYLESS-GO*
card (if so equipped) (
page 100).
If the vehicle interior is hot, ventilate
the interior before driving off.
Keep the air intake grille in front of the
windshield free of snow and debris.
Do not obstruct air volume by placing
objects on the air volume-through ex-
haust slots below the rear window.
