Never fold a windshield wiper arm without
a wiper blade back onto the windshield/
rear window.
Hold the windshield wiper
arm
firmly when
you change the wiper blade. If you release
the wiper arm without a wiper blade and it
falls onto the windshield/rear window, the
windshield/rear window may be damaged
by the force of the impact.
Mercedes-Benz recommends that you have
the wiper blades changed at a qualified
specialist workshop.
! To avoid damaging the wiper blades,
make sure that you touch only the wiper
arm of the wiper.
Changing the windshield wiper blades Moving the wiper blades to a vertical
position
!
Before changing the wiper blades,
always
set the wiper arms to a vertical position
using the combination switch. There is
otherwise a risk of damaging the hood.

Notes on using 3-zone automatic
climate control
Automatic climate control The following contains instructions and
recommendations to enable you to get the
most out of your automatic climate control.
R
Activate climate control using the 0058
and
005A buttons. The indicator lamps in the
0058 and 005A buttons light up.
R In automatic mode, you can also use the
00F0 button to adjust airflow (FOCUS/
MEDIUM/DIFFUSE). The MEDIUM level is
recommended.
R Set the temperature to 72 ‡ (22 †).
R Only use the "windshield defrosting"
function briefly until the windshield is clear
again.
R Only use air-recirculation mode briefly, e.g.
if there are unpleasant outside odors or
when in a tunnel. The windows could
otherwise fog up, since no fresh air is drawn
into the vehicle in air-recirculation mode.
R Use the ZONE function to adopt the
temperature settings on the driver's side
for the front-passenger side and the rear
compartment as well. The indicator lamp in
the 00D6 button goes out.
R Use the residual heat function if you want
to heat or ventilate the vehicle interior
when the ignition is switched off. The
residual heat function can only be activated
or deactivated with the ignition switched
off.
ECO start/stop function During automatic engine switch-off, the ECO
start/stop function only operates at a
reduced capacity. If you require the full
climate control output, you can
switch off the
ECO start/stop function by pressing the ECO
button ( Y page 146). Operating the climate control

Switching climate control on/off
Points to observe before use When the climate control is switched off, the
air supply and air circulation are also
switched off. Only use this setting for a brief
period. The windows could otherwise fog up.
Only switch off climate control briefly to
prevent the windows from fogging up.
