WARNING
The exterior mirrors reduce the size of the
image. Objects are actually closer than they
appear. You

could misjudge the distance from
vehicles driving behind and cause an
accident, e.g. when changing lane. For this
reason, make sure of the actual distance from
the vehicle driving behind by glancing over
your shoulder. X

sure that the SmartKey is in position
1 or 2 in the ignition lock.
X Press button : for the left-hand exterior

The indicator lamp goes out again after
some time. You can adjust the selected
mirror using adjustment button = as long
as the indicator lamp is lit.
X Press adjustment button = up, down, to
the right or to the left.
The exterior

mirror must be set to a position
that provides you with a good overview of
traffic conditions.
The convex exterior mirrors provide a larger
field of vision.

mirrors are automatically heated
if the rear window defroster is switched on
and the outside temperature is low.

WARNING
If incident light from headlamps is prevented
from striking the sensor in the rear-view
mirror, for

instance, by luggage piled too high
in the vehicle, the mirror's automatic anti-
glare function will not operate.
Incident light could then blind you. This may
distract you from the traffic conditions and,
as a result, you may cause an accident. Mirrors

Useful information
i This Operator's Manual describes all
models and all standard and optional
equipment of your vehicle available at the
time of publication of the Operator's
Manual. Country-specific differences are
possible. Please
note that your vehicle may
not be equipped with all features
described. This also applies to safety-
related systems and functions.

Important safety notes
G
WARNING
Observe the settings recommended on the
following pages. The windows could
otherwise fog

up. This could prevent you from
observing the traffic conditions, thereby
causing an accident. G
WARNING
Severe conditions (e.g. strong air pollution)
may require replacement of the filter before
its scheduled

replacement interval. A clogged
filter will reduce the air volume to the interior
and the windows could fog up, impairing
visibility and endangering you and others.
Have a clogged filter replaced as soon as
possible at a qualified specialist workshop.
Climate control regulates the temperature
and the humidity in the vehicle interior and
filters undesirable substances out of the air.
Climate control is only operational when the
engine is running. The system only works
optimally when the side windows and the roof
are closed.
The residual heat function can only be
activated or deactivated with the ignition
switched off (Y page 130). i
Ventilate the vehicle for a brief period
during warm

weather. This will speed up the
cooling process and the desired vehicle
interior temperature will be reached more
quickly.
i It is possible that the residual heat
function may be activated automatically an
hour after the SmartKey is removed. The
vehicle is then ventilated for 30minutes to
dry the air-conditioning system. 122
