• Always check that the wiper blades are not frozen to the glass
before you turn the wipers on. Loosen a wiper blade which is frozen
in place before operating the wipers to prevent damage to the wiper
blade or the wiper motor.
• Do not use the wipers to clear a frosted window. Using the
wipers as a convenient ice scraper will destroy the wiper blades.
• Before you take your vehicle to an automatic car wash, make sure
you have the windshield wiper system switched off (lever in position
Ol, otherwise the windshield wiper system could get damaged in the
car wash if it should suddenly come on .
[ i ] Tips
• The rain sensor is part of the interva l wiping system. Turning off
the ignition will also deactivate the rain sensor . To reactivate the
sensor, switch off the interval wiping function, then switch it back
on again.
• Worn or dirty windshield wiper blades cause smearing which
can affect the operation of the rain sensor. Check the condition of
your windshield wiper blades regularly.
• Make sure the washer fluid reservoir in the engine compartment
is topped off before going on a long trip. Look up~
page 312for
checking and filling the washer container .•

® with the headlights turned on by holding the
lever for longer than one second.
The washer jets extend forward out of the front bumper driven by
water pressure to spray the front headlights with water. You should inspect the headlights regularly (for example when refu­
e ling) and c lean off any so lid dirt or insects from the lenses.
To ensure the system works properly in winter, keep the washer jets
free of snow and remove any ice using a de -icing spray. •
Service position
The wiper blades can only be changed in the service posi­
tion.

ECON
The ECON mode helps to save fuel.
The air conditioning is turned off in ECON mode. "ECON" means
"Economy" . By switching off the air conditioning (compressor), you
save fuel.
Please note that vehic le interior temperature cannot be lower than
the outs ide temperature in the ECON mode . The air is not cooled or
dehumidified.
If the vehic le interior becomes too hot or if the windows fog up,
ECON mode should be turned off . As soon as the !AUTO
I button in
the air conditioning controls is p ressed, the system automatically
leaves the ECON mode, and the air conditioning compressor is
turned on again .•
Automatic recirculation mode
An air quality sensor detects incre ased concentratio ns of
pollutants in the outside air and aut omatically switches
to recirculation mode.
We recommend that you always keep automatic air recirculation ON
to prevent polluted outside air from entering the vehicle interior .
I f the
air qualit y sensor located in the air conditioning system
detects po lluted outside air, the sensor decides whether the air
pol lution can be reduced by the factory -installed po llutant filter or
whe ther it is necessary to swi tch to air recirculatio n. With heavy
concentrations of pol lutants, the air conditioning system is
sw itched automatically to rec irculation mode and the supp ly of
outside air is blocked . As soon as the concentration of pollutants in
the outside a ir drops, fresh air is supp lied to the vehic le inte rior
aga in.
I n the event that the windows fog up during automatic air recircu la ­
t ion, you must press the® button immed iately.
Under certain operating conditions , automatic air recircu lation is
sw itched off automatically. With outside temperatures be low about
+10 °C , automatic air recirculation is limited to 30 seconds. With
outside temperatures below about -1 °C and in the ECO N mode,
automatic air recirculation is limited to 15 seconds .•
Synchronization
One climate control se tting f or all seats.
With synchronization active, the driver 's or the passenger's settings
are adopted for the other seats . Al l the other settings that were
made are trans ferred to the other seats. This includes all the c limate
control settings right down to the heated seats.
I f a differen t setting is selected at a "synchronized seat", synchroni ­
z ation is cancelled .•

Adaptive Cruise Control
Speed and distance control system
Applies to vehic les : with Adaptive C ruise Cont rol
Description
The Adaptive Cruise Control driver assistance program is
a combined speed and distance control system.
Fig. 129 Front
bumper: Position of
radar sensor
Any speed between about 20 mph (30 km/h) and about 95 mph
(150 km/h) can be set and he ld with the Adaptive Cruise Con trol. The
system also regulates a pre-set distance from the vehicle ahead
within the limits of the system described.
Driving can be more relaxed, particularly on long trips on interstates
or on other highways that are generally straight.
How does it work?
You can operate the Adaptive Cruise Control using the lever on the
steering wheel column::::> page 137, "How is the speed stored?" and
=> page 140, "How is the distance (time interval) set?".
Con tro ls and eq uip­
ment
Driver information
Important information is brought up in the speedometer and in the
instrument cluster display as the vehicle is being driven
=> page 142, "Driver information" .
What is important for you to know
The Adaptive Cruise Control is set with system -specified limits, that
is, as a driver, you will have to adjust the speed and distance to the
vehic le ahead in some instances=> page 146, "Driver intervention
prompt" and=> page 147, "System limita tions".
& WARNING
Improper use of the Adaptive Cruise Control can cause collisions,
other accidents and serious personal injury .
• Never drive at speeds that are too high for traffic , road and
weather conditions.
• Never follow the vehicle in front so closely that you cannot stop
your vehicle safely. The Adaptive Cruise Control cannot brake the
vehicle safely when you follow another vehicle too closely. Always
remember that the Adaptive Cruise Control has a braking power
that is only about 25% of the vehicle's maximum braking ability,
the automatic braking function cannot bring the vehicle to a stop.
• Never use Adaptive Cruise Control on roads where you cannot
drive safely at a steady speed, including city, stop-and-go or heavy
traffic, on winding roads or when road conditions are poor (for
example, on ice, gravel , in fog , heavy rain or on wet roads that
increase the risk of hydroplaning).
• The radar sensor's
vision can be reduced by rain, snow and
heavy spray. This can result in vehicles driving ahead being inade ­
quately detected or, in some circumstances, not detected at all. If
necessary , take action yourself! ._
Vehicle care I I irechnical data

• .___A_ d_ a_ p =- t_iv _ e _ C_ r_u _is_ e_ C _ o_ n_ t _r _o_ l --------------------------------------------
& WARNING (continued)
• Always turn off Adaptive Cruise Control when entering turn
lanes, highway exit lanes and construction zones or similar situa ­
tions because the vehicle will automatically accelerate to the
stored speed.
• Never rest your foot on the accelerator pedal, especially when
the Adaptive Cruise Control is being used because doing so will
override the braking function and prevent the brakes from being
applied by the system when it detects a situation when the brakes
must be applied.
• Always remember that the Adaptive Cruise Control has limits -
it does not react when you drive towards an obstacle or some­
thing else on or near the road that is not moving, such as vehicles stopped in a traffic jam, a stalled or disabled vehicle .
• Always remember that the Adaptive Cruise Control cannot
detect a vehicle that is driving towards you in your traffic lane and
that it cannot detect narrow vehicles such as motorcycles and
bicycles .
[ i) Tips
• For safety reasons, the stored speed is deleted when the ignition
is turned off.
• The Electronic Stabilization Program (ESP) and the Anti -Slip
Regulation (ASRl cannot be deactivated when the Adaptive Cruise
Control is switched on. If the ESP and the Anti -Slip Regulation (ASRl
has been deactivated and you then switch on the Adaptive Cruise
Control, the ESP function will also be activated automatically.
• Damage caused by accidents (e.g. if the vehicle is damaged
when parking) can affect the radar sensor settings. This can cause
the system to malfunction or switch off completely.
• The radar sensor cover is heated. In winter conditions, you
should still check before driving to make sure it is free of ice and
snow. If necessary, clean the area near the radar sensor carefully
=>
page 135, fig. 129. • To
ensure that the radar sensor is not blocked, foreign objects
(e.g. stickers, larger license plate mounts, add -on parts) must not
cover the area near the radar sensor=>
page 135, fig. 129. The area
near the radar sensor must not be painted, either. •
Applies to veh ic les: with Adaptive Cruis e Contro l
How does Adaptive Cruise Control work?
Vehicles traveling ahead are detected with the aid of a
radar sensor.
Fig. 130 Radar sensor
measurement range
A radar sensor is built into the front of the vehicle=> fig. 130. The
system is intended to measure the distance to reflective surfaces. If
a measurement is not possible, the system does not respond.
Open road
When the road is clear, the Adaptive Cruise Control works like cruise
control. It maintains a constant target speed specified by the driver.
Driving in traffic
If a vehicle driving ahead is detected, the Adaptive Cruise Control
decelerates (within the limits of the system)=>
page 146, "Driver
intervention prompt" and=>
page 147, "System limitations" to its
speed and after adjusting, tries to maintain the set distance from
the vehicle ahead. The vehicle may temporarily drive slower than
the set speed while adjusting=>
& in "Description" on page 135. .,

The different symbols for the time intervals appear if you change the
settings ~ fig. 139 .
The text message ... (three white dots) appears if a setting cannot be implemented with the operating lever . The following are possible
reasons:
• If you pul l the control lever towards you to resume speed but no
requested speed was set .
• I f you push the lever up to increase (or down to reduce) speed
when no speed has been set previously.
• If you push the lever up to increase (or down to reduce) speed
and this speed is outside the range from 20 to 95 mph (Canada
models : 30 to 150 km/h) .
ACC fun cti ona lity limited
The text message AC C functionalit y limited appears when the ACC
System does not detect any objects over an extended time period.
For the time being, the distance to vehicles up ahead is not being
Con tro ls and eq uip­
ment
controlled. The ACC system is not switched off, so increased alert­
ness is required. The following may be reasons for the text message
ACC Functiona lly limited:
• The ACC sensor is dirty. The ACC system is not reacting, or is not
reacting correctly, to veh ic les travel ing ahead.
• I t is possible that you are driving on a road with very light traffic
without anything at the side of the road (e.g. guard rai ls, traffic
signs, trees). As soon as a vehicle is detected by the system again,
it returns to its control range and the text message disappears .
The ACC sensor is located in the area under the front license plate.
If there is a loss of operation due to heavy contamination, this area
should cleaned to restore proper operation .
ACC not available
The text message ACC n ot ava ila ble appears, for example, if the
t emperature of the brakes is excessive. Adap tive Cruise Control is
temporarily not available . A warning tone sounds as a reminder .
ACC not available!
The text message ACC not ava ilable ! appears in the event of a
malfunction . Adaptive Cruise Contro l is tur ned o ff. A warning to ne
sounds as a reminder. Have the system inspected by a qua lified
dea lership .
ACC se nsor bl ocked !
The text message AC C sensor blocked ! appears when the ACC
System can no longer guarantee safe detection of objects . Adaptive
cruise control is turned off. A chime sounds as a rem inder .
To decide whether it is necessary to switch off the ACC (ACC sensor
blocked
!) or if it is only a temporary condition (ACC functionality
limited), the system wi ll also takes into consideration the outside
temperature and/or the windshield wiper operation.
The ACC sensor is dirty o r blocked (e .g . leaves, sn ow).

In cer tain situati ons, the braking power of t he Adaptive cruise
control is not sufficient to maintain an adequate distance from the
object ahead. In this situation, the Adap tive cruise contro l ca lls on
you as the driver to take action.
The

[ i ] Tips
• I f the Adaptive cruise control initiates braking, the hydraul ic
brake system is under pressure. Therefore, the brake peda l distance
is shorter and the pedal "feels" harder.
• Adaptive Cruise C ontro l is switched off af ter pressing the foot -
brake. The speed
saved up this point can be resumed. _,,,
