3-zone automatic climate control*
The automatic climate control is a 3-zone
intelligent automatic climate control sys-
tem. Your vehicle interior is divided into
3 zones.With the help of a sun sensor, the automat-
ic climate control determines the relation
of the sun to the vehicle and automatically
adjusts the inside temperature for every
individual zone.
The automatic climate control is operation-
al whenever the engine is running. It cools
the vehicle’s interior according to the an-
gle and intensity of the sun’s rays, the out-
side temperature and the selected
temperature. You can operate the auto-
matic climate control in either the auto-
matic or manual mode.
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 A/C mode is deactivated
(
page 232).
Warning!G
When operating the automatic climate con-
trol, the air that enters the passenger com-
partment through the air vents can be very
hot or very cold (depending on the set tem-
perature). This may cause burns or frostbite
to unprotected skin in the immediate area of
the air vents.
Always keep sufficient distance between un-
protected parts of the body and the air
vents. If necessary, use the air distribution
controls (
page 232) to direct the air to air
vents in the vehicle interior that are not in
the immediate area of unprotected skin.

Driver’s door only:
If within 5 seconds switch is again pulled
past the resistance point and released, the
automatic reversal will not function.
iIf the upward movement of a door window is
blocked during the closing procedure, the door
window will stop and open slightly.
iIf the door window still does not close when
there is no obstruction, pull and hold the respec-
tive power window switch. The door window will
then close without the obstruction sensor
function.

Press and release switch2 once
more.
Synchronizing the door windows
The door windows must be resynchronized
after the battery was disconnected
if the door windows cannot be fully
opened (Express-open) or closed
(Express-close)
Close all doors.
Switch on the ignition (page 42).
Pull and hold switch1, 2,3, or6
(
page 248).
Once a door window is closed com-
pletely, hold the respective switch for
approximately 3 seconds.
The door window is synchronized.
Summer opening feature
If the weather is warm, you can ventilate
the vehicle before driving off by simulta-
neously:
opening the door windows
opening the hinged quarter windows*
opening the tilt/sliding sunroof*
switching on the seat ventilation* for
the driver’s seat
Aim transmitter eye of the SmartKey or
SmartKey with KEYLESS-GO* at the
driver’s outside door handle.
The SmartKey or SmartKey with
KEYLESS-GO* must be in close proxim-
ity to the driver’s outside door handle.
Press and hold buttonŒ on the
SmartKey or SmartKey with
KEYLESS-GO* until the windows and
the tilt/sliding sunroof* have reached
the desired position.
Release buttonŒ on the SmartKey
or SmartKey with KEYLESS-GO* to
interrupt the opening procedure.
iWhen the obstruction sensor detects the
hinged quarter window is blocked during the
closing process, it will stop and open slightly.
iEach door window must be resynchronized
separately.

Driving systems
Setting to last stored speed
(“Resume” function)
Briefly pull the cruise control lever in di-
rection of arrow4 (
page 258).
The cruise control resumes to the last
set speed, or if no speed is stored, it
will set and store the current speed.
Remove your foot from the accelerator
pedal.
The last set speed appears in the multi-
function display for approximately
5 seconds.
Distronic*
When activated, the Distronic adaptive
cruise control system increases the driving
convenience afforded by the cruise control
while traveling on expressways and other
major roadways.
If the Distronic distance sensor detects
a slower moving vehicle directly ahead,
your vehicle speed will be reduced so
that you follow that vehicle at your
preset following distance.
If there is no vehicle directly ahead of
you, Distronic will function in the same
way as standard cruise control
(
page 257).
Warning!G
The set speed stored in memory should only
be set again if prevailing road conditions
permit. Possible acceleration or decelera-
tion differences arising from returning to the
preset speed could cause an accident
and/or serious injury to you and others.
Warning!G
Distronic is a convenience system. Its speed
adjustment reduction capability is intended
to make cruise control more effective and
usable when traffic speeds vary. It is not
however, intended to, nor does it, replace
the need for extreme care. The responsibili-
ty for the vehicle’s speed, distance to the
preceding vehicle and, most importantly,
brake operation to ensure a safe stopping
distance, always remains with the driver.
Distronic cannot take road and traffic condi-
tions into account.
Complex driving situations are not always
fully recognized by Distronic. This could
result in wrong or missing distance
warnings.
263 Controls in detail
Driving systems
Warning!G
Distronic adaptive cruise control is no
substitute for active driving involvement. It
does not react to pedestrians or on station-
ary objects, nor does it recognize or predict
the lane curvature or the movement of
preceding vehicles.
Distronic can only apply a maximum of 20%
of the vehicle’s braking power.
It is the driver’s responsibility at all times to
be attentive to the road, weather and traffic
conditions. Additionally, the driver must
provide the steering, braking and other
driving inputs necessary to remain in control
of the vehicle.
High-frequency sources such as toll
stations, speed measuring systems etc. can
cause the Distronic system to malfunction.
Warning!G
Distronic requires familiarity with its opera-
tional characteristics. We strongly recom-
mend that you review the following
information carefully before operating the
system.
Warning!G
Distronic cannot take road and traffic condi-
tions into account. Only use Distronic if the
road, weather and traffic conditions make it
advisable to travel at a constant speed.
Warning!G
Use of Distronic can be dangerous on slip-
pery roads. Rapid changes in tire traction
can result in wheel spin and loss of control.
Distronic does not act upon adverse sight
and distance conditions. Do not use
Distronic during conditions of fog, heavy
rain, snow or sleet.
Warning!G
Distronic cannot take weather conditions
into account. Switch off Distronic or do not
switch it on if:
roads are slippery or covered with snow
or ice. The wheels could lose traction
while braking or accelerating, and the
vehicle could skid.
the sensor is dirty or visibility is
diminished due to snow, rain or fog, for
example. The distance control system
functionality could be impaired.
Always pay attention to surrounding traffic
conditions even while Distronic is switched
on. Otherwise, you may not be able to recog-
nize dangerous situations until it is too late.
This could cause an accident in which you
and others could be injured.

Driving systems
Warning!G
The “Resume” function should only be
operated if the driver is fully aware of the
previously set speed and wishes to resume
this particular preset speed.
Warning!G
Close attention to road and traffic condi-
tions is imperative at all times, regardless of
whether or not Distronic is activated.
Use of Distronic can be dangerous on
winding roads or in heavy traffic because
conditions do not allow safe driving at a
continuous speed.
Distronic will not react to stationary objects
in the roadway (e.g. a stopped vehicle in a
traffic jam or a disabled vehicle). Distronic
will also not respond to oncoming vehicles.
Switch off Distronic:
when changing from the left to the right
lane if vehicles are moving more slowly
in the left lane
when entering a turn lane or highway off
ramp
in complex driving situations, such as in
highway construction zones
In these situations, Distronic will continue to
maintain the set speed unless deactivated.
Distronic is designed and intended only to
maintain a set speed and keep a set dis-
tance from moving objects in front of it.
