Problems with the steering wheel heating
ProblemPossible causes/consequences and MSolutions
The steering wheel heat-
ing has switched off pre-
maturely or cannot be
switched on.The on-board voltage is too low because too many electrical consum-
ers are switched on.
XSwitch off electrical consumers that you do not need, such as the
rear window defroster or interior lighting.
EASY-ENTRY/EXIT feature
Important safety notes
GWARNING
When the EASY-ENTRY/EXIT feature adjusts
the steering wheel, you and other vehicle
occupants – particularly children – could
become trapped. There is a risk of injury.
While the EASY-ENTRY/EXIT feature is mak-
ing adjustments, make sure that no one has
any body parts in the sweep of the steering
wheel.
Move the steering wheel adjustment lever if
there is a risk of entrapment by the steering
wheel. The adjustment process is stopped.
Press one of the memory function position but-
tons. This function is only available on vehicles
with memory function.
GWARNING
If children activate the EASY-ENTRY/EXIT fea-
ture, they can become trapped, particularly
when unattended. There is a risk of injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.
GWARNING
If you drive off while the EASY-ENTRY/EXIT
feature is making adjustments, you could lose
control of the vehicle. There is a risk of an
accident.
Always wait until the adjustment process is
complete before driving off.
The EASY-ENTRY/EXIT feature makes getting in
and out of your vehicle easier.
You can activate and deactivate the EASY-
ENTRY/EXIT feature in the on-board computer
(
Ypage 217).

to the correct position. You should have a
good overview of traffic conditions.
The convex exterior mirrors provide a larger field
of vision.
The exterior mirrors are heated automatically if
the rear window defroster is switched on and the
outside temperature is low.
Folding the exterior mirrors in or out
electrically
XTurn the SmartKey to position 1or 2in the
ignition lock (Ypage 125).
XBriefly press :.
Both exterior mirrors fold in or out.
iMake sure that the exterior mirrors are
always folded out fully while driving. They
could otherwise vibrate.
iIf you are driving faster than 30 mph
(47 km/h), you can no longer fold in the exte-
rior mirrors.
Resetting the exterior mirrors
If the battery has been disconnected or com-
pletely discharged, the exterior mirrors must be
reset. Otherwise, the exterior mirrors will not
fold in when you select the "Fold in mirrors when
locking" function in the on-board computer
(
Ypage 217).
XTurn the SmartKey to position 1in the ignition
lock (Ypage 125).
XBriefly press :.
Folding the exterior mirrors in or out
automatically
If the "Fold in mirrors when locking" function is
activated in the on-board computer
(
Ypage 217):
Rthe exterior mirrors fold in automatically as
soon as you lock the vehicle from the outside.
Rthe exterior mirrors fold out again automati-
cally as soon as you unlock the vehicle and
then open the driver's or front-passenger
door.
Exterior mirror pushed out of position
If an exterior mirror has been pushed out of
position, proceed as follows:
XVehicles without electrically folding exte-
rior mirrors: move the exterior mirror into
the correct position manually.
XVehicles with electrically folding exterior
mirrors: press and hold mirror-folding but-
ton :until you hear a click and the mirror
engages in position audibly.
The mirror housing is engaged again and you
can adjust the exterior mirrors as usual
(

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
the humidity in the vehicle interior and filters
undesirable substances out of the air.
The residual heat function can only be activated
or deactivated with the ignition switched off
(
Ypage 121).
iVentilate the vehicle for a brief period during
warm weather, e.g. using the convenience
opening feature (
Ypage 84).
This will speed up the cooling process and the
desired interior temperature will be reached
more quickly. If you start the engine using your smartphone,
the last selected climate control setting is reac-
tivated (
Ypage 127).
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.
iVehicles with AIR-BALANCE package: in
addition to ionization, the vehicle has an air
filter with anti-allergenic properties that con-
tribute to improved air filtration.
iIt is possible that under certain circumstan-
ces the residual heat function may be activa-
ted automatically an hour after the SmartKey
has been removed in order to dry the auto-
matic climate control. The vehicle is then ven-
tilated for 30 minutes.

Information about using automatic
climate control
Optimum use of the automatic climate
control
The following contains notes and recommenda-
tions on optimum use of the dual-zone or 3-zone
automatic climate control.
RYou can switch on climate control by using the
à and¿ orà andÁ buttons.
The indicator lamps in the Ãand
¿ buttons or the ÃandÁ buttons
light up.
RVehicles with 3-zone climate control:in
automatic mode, you can also use the
ñ button to set a climate mode (FOCUS/
MEDIUM/DIFFUSE). The MEDIUM level is
recommended.
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.
RVehicles with 3-zone climate control: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 above the ábut-
ton goes out.
RVehicles with 3-zone climate control:use
the "residual heat" function if you want to heat or ventilate the vehicle interior when the igni-
tion is switched off. The residual heat functio
n
ca
n only be activated or deactivated with the
ignition switched off.
RIf you change the settings of the climate con-
trol system, the climate status display
appears for approximately three seconds at
the bottom of the screen in the multimedia
system display. You will see the current set-
tings of the various climate control functions.
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 130).
