All turn signals flash. If you now switch on a
turn signal using the combination switch, only
the turn signal lamp on the corresponding
side of the vehicle will flash.
XTo switch off the hazard warning lamps:
press button :.
The hazard warning lamps automatically switch
on if:
Ran air bag is deployed or
Rthe vehicle decelerates rapidly from a speed
of above 45 mph (70 km/h) and comes to a
standstill
The hazard warning lamps switch off automati-
cally if the vehicle reaches a speed of above
6 mph (10 km/h) again after a full brake appli-
cation.
The hazard warning lamps still operate if the
ignition is switched off.
Cornering light function
The cornering light function improves the illu-
mination of the road over a wide angle in the
direction you are turning, enabling better visi-
bility in tight bends, for example. It can only be
activated when the low-beam headlamps are
switched on.
Active:
Rif you are driving at speeds below 25 mph
(40 km/h) and switch on the turn signal or
turn the steering wheel
Rif you are driving at speeds between 25 mph
(40 km/h) and 45 mph (70 km/h) and turn
the steering wheel
The cornering lamp may remain lit for a short
time, but is automatically switched off after no
more than three minutes.

This Operator's Manual describes all models
and all standard and optional equipment of
your vehicle available at the time of publica-
tion of the Operator's Manual. Country-spe-
cific 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.

Overview of climate control systems
General notes
Observe the settings recommended on the fol-
lowing pages. The windows could otherwise fog
up.
To prevent the windows from fogging up:
Rswitch off climate control only briefly
Rswitch on air-recirculation mode only briefly
Rswitch on the cooling with air dehumidifica-
tion function
Rswitch on the defrost windshield function
briefly, if required
Climate control regulates the temperature and
air humidity in the vehicle interior. The air filter
cleans the air, thus improving the interior cli-
mate.
For vehicles with a combustion engine, the
"Cooling with air dehumidification" function is
only available when the engine is running. For
hybrid vehicles, the "Cooling with air dehumidi-
fication" function is also available via the elec-
tric refrigerant compressor when the engine is
not running. Optimum climate control is only
achieved with the side windows and roof closed.
If you start the engine using your smartphone,
the last selected climate control setting is reac-
tivated (
Ypage 164).
The residual heat function can only be activated
or deactivated with the ignition switched off
(
Ypage 152).
iVentilate the vehicle for a brief period during
warm weather, e.g. using the convenience
opening feature (
Ypage 95). This will speed
up the cooling process and the desired inte- rior temperature will be reached more
quickly.
iThe integrated filter filters out most parti-
cles of dust and soot and completely filters
out pollen. It also reduces gaseous pollutants
and odors. A clogged filter reduces the
amount of air supplied to the vehicle interior.
For this reason, you should always observe
the interval for replacing the filter, which is
specified in the Maintenance Booklet. As it
depends on environmental conditions, e.g.
heavy air pollution, the interval may be
shorter than stated in the Maintenance Book- let.
iIt is possible that the blower may be activa-
ted automatically 60 minutes after the Smart-
Key has been removed depending on various
factors, e.g. the outside temperature. The
vehicle is then ventilated for 30 minutes to dry
the climate control system.

Notes on using automatic climate
control
Climate control system
Below, you can find a number of notes and rec-
ommendations to help you use climate control
optimally.
RActivate climate control using the Ã
rocker switch. The indicator lamp in the Ã
rocker switch lights up.
RSet the temperature to 72 ‡ (22 †).
ROnly use the "Windshield defrosting" function
briefly until the windshield is clear again.
ROnly 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.
RUse 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. The residual
heat function is switched off when the ignition
is switched on.
If you are controlling the rear-compartment cli-
mate control using the front control panel, note
the following:
RIf you set rear-compartment climate control
using the front control panel, the Ysym-
bol appears in the rear-compartment control
panel display.
RIf the rear-compartment climate control is set
using the front control panel, it cannot be set
at the same time using the rear control panel. After completing the settings for the rear-
compartment climate control using the front
control panel, wait five seconds. You will then
be able to control the rear climate control
using the rear control panel.
RAfter selecting the rear compartment set-
tings, the front climate control can be con-
trolled automatically again via the multimedia
system after five seconds.
Alternatively, you can select "Cancel rear
compartment" in the multimedia system air-
conditioning function bar.
ECO start/stop function
During automatic engine switch-off, the climate
control system only operates at a reduced capa-
city. If you require the full climate control output,
you can switch off the ECO start/stop function
by pressing the ECO button (
Ypage 167).

Switching cooling with air dehumidi-
fication on/off
General notes
If you deactivate the "Cooling with air-dehumid-
ification" function, the air inside the vehicle will
not be cooled. The air inside the vehicle will also
not be dehumidified. The windows can fog up
more quickly. Therefore, deactivate the cooling
with air-dehumidification function only briefly. For vehicles with a combustion engine, the
"Cooling with air dehumidification" function is
available when the engine is running. For hybrid
vehicles, the "Cooling with air dehumidification"
function is also available via the electric refrig-
erant compressor when the engine is not run-
ning. The air inside the vehicle is cooled and
dehumidified according to the temperature
selected.
Condensation may drip from the underside of
the vehicle when it is in cooling mode. This is
normal and not a sign that there is a malfunc-
tion.
Switching on/off
XTo activate: press theÁrocker switch up
or down.
The indicator lamp above the rocker switch
lights up.
or
XActivate the "Cooling with air dehumidifica-
tion" function via the multimedia system (see
the separate operating instructions).
XTo deactivate: press theÁrocker switch
up or down.
The indicator lamp above the rocker switch
goes out.
or
XDeactivate the "Cooling with air dehumidifi-
cation" function via the multimedia system
(see the separate operating instructions).
