ECON
The ECON mode helps to save fuel .
The air conditioning is turned off in ECON mode. "ECON" means
" E conomy". By switching off the air conditioning (compressor), you
save fuel.
Please note that vehicle interior temperature cannot be lower than
the outside temperature in the ECON mode. The air is not cooled or dehumidified .
If the vehicle inter ior becomes too hot or if the windows fog up, ECON
mode should be turned off. As soon as the
( AUTO] button in the air
conditioning controls is pressed, the system automatically leaves the
ECON mode, and the air conditioning compressor is turned on
again. •
Automatic recirculation mode
An air quality sensor detects increased concentrations of
pollutants in the outside air and automatically switches
to recirculation mode .
We recommend that you always keep automat ic air recirculat ion ON
to prevent polluted outside air from entering the vehicle interior.
If the
air quality sensor located in the air conditioning system detects
polluted outside air, the sensor decides whether the air pollution can
be reduced by the facto ry-insta lled pollutant fi lter or whe ther it is
necessary to switch to air recirculation. With heavy concentrations of
pollutants, the air conditioning system is switched a utomat ically to
recirculation mode and the supply of outside air is blocked . As soon .,.

Adaptive Cruise Control has technica l limitations that you must k now,
so p le a se read this sectio n carefully, understa nd how the sy stem
works and use it p ro p erly at all ti mes.
How does it work?
You ca n op erate the Adaptive Cruise Control usi ng the lever on the
s teer ing wheel column ~
page 13 1, " H ow is the speed sto red?" and
~ page 133, " H ow is the distance set?" .
Driver information
Important information is bro ught up in the s peedometer and in the
i nst rumen t clust er displa y as the ve hicl e is be ing drive n~
pa ge 135,
"Driver informat io n".
What is important for you to know
T here are limits to what Adaptive Cr uise Contro l can do as the vehicle
is being drive n~
page 139 , "Sys tem lim itations".
& WARNING
Improper use of the Adaptive Cruise Control can cause collisions,
other accidents and serious personal injury.
• Always remember that the Adaptive Cruise Control has limits -
it will not slow the vehicle down or maintain the set distance when
you drive towards an obstacle or something 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 nar row vehicles such as motorcycles and bicy­
cles.
• Never drive at speeds that are too fast for traffic, road and
weather conditions.
• The Adaptive Cruise Control cannot slow
or 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 30% of the vehicle 's maximum braking ability .
Always be prepared to brake and take ev asive action to avoid colli·
sions and other accident situations.
• Never allow the closing speed between you and other vehicles
to be so high that the Adaptive Crui se Control may not be able to .,

__________________________________________ A_ d_ a_,_ p_t _iv _ e_C_ r_u _i _ s _e _C_ o_n_ t_ r_ o_ l __ _
& WARNING (continued)
slow your veh icle safely. If clos ing speed is too high , you must
apply the brake s your self to reduc e the ri sk of a rear-end cra sh .
• Never re st you r foot on the accelerator pedal , especially when
the Adaptive Cruise Control is being used. Pressure on the acceler­
ato r will override the ACC braking function and prevent the brakes
from being applied when ACC detects a situation when the brakes
must be applied.
• Never use Adaptive Cruise Control when you cannot drive safely
at a steady speed, including on city st reets , 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 ris k of hydroplaning ).
• The radar sensor's
vision can be reduc ed by rain, snow and
heavy road spray . These and similar conditions can prevent vehi ­
cle s up ahead from being accurately detected and in some cases
they may not be detected at all . Do not use ACC when the radar
sen sors cannot ac curately detect vehicles moving ahead of you in
traffic .
• Alway s turn off Adaptive Crui se Control when entering turn
lanes , exit lanes and construction zones o r in similar situat ions
because the vehicle will automatically ac celerate to the stored
speed when the road ahead is clear .
• To prevent unintended operation , always switch ACC off when
it is not being used .
[ i] Tips
• For safety reasons, the stored speed is deleted when the ignition
i s turned o ff.
• When Adapt ive Cruise Control is switched on, the Electronic Stabi­
li zation Program ( ESP) is also automa tica lly activ ated.
• Damage caused by accidents and some minor collisions can affect
th e rad ar senso r se ttings and ca use the syste m to m alfunction o r
switch off completely.

General information
The radar sensor has limits that the driver must know to
be able to use ACC properly.
The Adaptive Cruise Control works within limits that are also related
to radar sensor range and sight distance. In some situations ACC may
react unusually or late from the driver's point of v iew. Therefore,
always be attentive to what is happe ning around you and always be
ready to intervene, if necessary:
• when driving around curves=>
page 139.
• when vehicles up front are not in line with your vehicle
=>
page 140 .
• when other vehicles are changing lanes=> page 140.
• when other vehicles are difficult to detect=> page 140 .
• when vehicles up ahead are no t moving or obstacles are in your
travel lane=>

The detection~ page 146, fig. 161 of the radar sensor detection
area is made up of :
• the approach area (light green area)
(D, about 230 feet (70 m)
behind the vehicle, and
• the "blind spot" (dark green area)@.
The radar sensors cover the adjacent left and right lanes. Other lanes are
not cove red by the radar sensors.
rn Tip s
Side assist does not measure act ual lane width. The system assumes
a fixed lane w idth. Detection in the left and right lanes is based on
this assumed lane w idth. When driving on narrow roads or when
driving to the left or right of the center of a travel lane, it is possible
that vehicles will be detected that are
not in the lane next to the lane
you are using~
page 151. •
Applie s to ve hicl es: w ith s id e a ssist
Operation
Side assist compares the distance and difference in speed of detected
vehicles with the speed of your vehicle . Whenever the difference in
speed and distance is registered as notab le if you were to change
lanes, a signa l light appears on the respect ive m irror .
The signa l can light up if you are passed by a vehicle or if you are
passing another vehicle.
If you pass another vehicle slowly (d ifference in speed less than 9
mph, or 15 km/h) , the signa l light will come on as soon as the other
vehicle is in your blind spot and is detected by side ass ist . When the
difference in speed is greater, the signal light wi ll not come on. •

pp lies to ve hicles : w ith side assist
Informational and alert stage signals
S ide assis t has two signa l st ages:
• the informational stage signal, and
• t he ale rt stage signal.
S ide assist helps you by using the appropr iate s ignal stage,
depending on whether or not you have activated the turn signal, and
thus have indicated that you are or are not changing lanes .
Informat ional stage signal
As long as you have not activated the turn signal, side assist informs
you of detected vehicles that are registered as being in a notable loca­
tion if you were to change lanes . Wheneve r the detected vehicle 's
difference in speed and distance is registered by side assist as
notable, the signal l ight on the respective m irror produces muted
illumination .
Th e br ightness of the info rmationa l stage signal is designed no t to be
as intense, so that it does not interfere w ith your v iew of the road
when you are driving and have no in tention of chang ing lanes. When
you look in the outside mirror, you can clearly see the informat ional
stage signal.
Alert stage signal
Whe n you act ivate the tu rn s ignal, a nd side assist has de tected a
vehicle in a notable location on that particular side, the signal light on
this side mirro r flashes b rightly. The repeated brief and bright
flash ing of the alert stage signal reminds you to carefully check
traffic to the rear in the outside mirror and over your shoulder, so t hat
you can safely complete the lane change~
