brake and take evasive action to avoid
collisions and other accident situations.
- Never allow the closing speed between
you and other vehicles to be so high that
the adaptive cruise control may not be
able to slow your vehicle safely. If clos­
ing speed is too high, you must apply the
brakes yourself to reduce the risk of a
rear-end crash.
- Never rest your foot on the accelerator peda l, especia lly when the adaptive
cruise control is be ing used. Pressu re on
the accelerator w ill override the ACC
braking function and prevent the brakes
from being applied when ACC detects a
situation when the brakes must be ap­
plied.
- Never use adaptive cruise contro l when
you cannot drive safe ly at a steady
speed, including on city streets, on wind­
ing 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 road spray.
T hese and sim ilar condit ions can prevent
vehicles up a head from being accurately
detected and in some cases they may not
be detected at al l. Do not use ACC when
the radar sensors cannot accurately de­
tect vehicles moving ahead of yo u in traf­
fic.
- Always turn off adaptive cruise contro l
when entering turn lanes, exit lanes and
construction zones or in similar situa­
t ions because the vehicle will automati­
cally accelerate to the stored speed when
the road ahead is clear.
- To prevent unintended operation, always
switch ACC off when it is not be ing used.
(D Tips
- For safety reasons, the stored speed is
deleted when the ignition is turned off .
- The E lectronic Stab ilizat ion Control (ESC)
and the Anti-Slip Regulation (ASR) can­ not be deactivated when the adaptive cruise contro
l is switched on . If the ESC
and the Anti-Slip Regu lation (ASR) has
been deactivated and you then switch on
the adaptive cruise control, the ESC func­ tion will also be activated automatically.
- Damage caused by accidents and some m inor collisions can affect the radar sen­
sor settings and cause the system to
ma lf u nction or switch off completely.
- The radar sensor cover is heated. In win­
ter conditions, you should st ill check be­
fore dr iv ing to make su re it is free of ice
and snow. If necessary, clean the a rea
nea r the radar sensor ca refully
¢ fig. 126.
- To ensure that the radar sensor is not
bloc ked, foreig n objects (e.g. s tickers,
larger license plate mount s, add -on
par ts) mus t not cover the area near the
radar sensor ¢
fig. 126 . The area near
the radar sensor must not be pa inted, ei­
ther.

How does adaptive cruise control work?
Applies to vehicles : wit h adaptive c ruise contro l
Vehicles traveling ahead are detected with
the aid of a radar sensor .
Fig. 1 27 Bas ic pri ncip le d iag ram : Radar sensor meas ­
urement range
Adaptive cruise control uses a rada r senso r in
t h e front of the vehicle ¢
fig. 12 7. The system
has limitat ions ¢
page 125. Things that are
not moving in your lane and in your direction
of travel will not be detected. The sensor
measures the distance to reflect ive surfaces ..,.

that must have a certain size. The system re­
sponds only after the distance measurement has been made. If a measurement is not pos­
sible, the system cannot respond and w ill not
react to a vehicle or someth ing else up ahead.
Open road
When the road is clear, the adaptive cruise
contro l works like cr uise control. It maintains
a constant target speed specified by the driv­
er.
Driving in traff ic
If a slowe r vehicle driving ahead is detec ted,
the adaptive cruise contro l decelerates (within
the limits of the system)

limitations
to its speed and after adjust ing,
tr ies to maintain the set distance from the ve­
h icle ahead. The vehicle may temporarily drive
slower than the set speed while adjust ing
¢ & in Description on page 113 .
If the vehicle in front accelerates, adaptive
cruise control also accelerates up to the speed
that you have set.
If the vehicle ahead slows to a stop, ACC will
slow your vehicle down and to a complete
stop if this is possible w ith in the system's lim ­
its and capabilities . ACC will not make an
emergency stop. The text message
ACC off :
manual c ontrol!
appears in the instr ument
cluster display . Once the veh icle stops, you
must depress the brake pedal to prevent the
vehicle from moving forward or "creeping". Depressing the brake pedal turns
off ACC.
When the veh icle ahead accelerates you can
reactivate ACC
¢ page 118, as soon as your
ve hicle has reached a speed of 1 mph (2 km/
h) .
Situ ation s re quiring dri ver int ervention
In some s ituations you w ill have to use the
footbrake to s low the vehicle down in order to
keep a safe distance from vehicle in front of
you or to avo id a rear-end coll is ion. In this sit­
uation, a symbol appears and a warning tone
sounds
¢ page 124.
Ada pti ve crui se control 115
Passing another vehicle
If you move in to the passing lane and no ve hi­
cle is detected ahead, the adaptive cr uise con­
trol acce le rates to the speed you have set and
maintains it.
Overr iding ACC
You can in cr ease yo ur speed at a ny time by
stepping on the accelera tor ped al. A fter you
release the accelerator peda l, the system ad­
justs back down to the speed you prev ious ly
set .
Reducing stopp ing distance
If the radar sensor detects that the d istance
to the vehicle a head is less than de fined m ini­
mum distance, the brakes are automatically
prepared fo r emergency braking by the driver .
The brake pads are moved very close to the brake d iscs without actually braking the vehi­
cle. This brake assistant feature reacts more
quick ly to the dr ive r's brak ing, and also works
when adapt ive cruise control is off . The stop­
ping distance is reduced as a result of th is ad­
vance brake p reparation . Th is fun ction does
not perform any emergency b rak ing mane u­
vers by itse lf; the dr iver mus t always apply the
brakes.
A WARNING
If ACC initiates a braking maneuver, the brake pedal w ill be retracted. Inter ference
with the brake peda l can prevent ACC from
slowing the veh icle down and cause a
crash and serious personal injury.
- Never put anything in the driver's foot­
well or let anyth ing fall into it. An object
in the driver's footwe ll can interfe re with
the peda ls and prevent the acce le rator
from being used to override ACC or pre­
vent ACC from being switched off when
the brake pedal is depressed and also
prevent the vehicle from being slowed
down or stopped .
- On ly use floor mats that keep the area
around the peda ls free and that can be
securely fastened to the footwell .

_& WARNING
Improper use of the adaptive cruise con­
trol features and inattention can lead to a
crash and serious personal injury.
- Never allow the closing speed between
you and othe r vehicles to be so high that
the adaptive cruise contro l may not be
able to slow your vehicle safely. If clos­
ing speed is too high, you must apply the
brakes yo urself to reduce the risk of a
rear-end crash.
- Always select a greater following d is ­

The ACC sensor is dirty or blocked (e.g. leaves,
snow).
The ACC sensor is located behind the area to
the right of the front license plate . If the ACC
sensor is dirty or blocked, clean the area to re­
store system operat ion.
ACC off: Manual control!
The text message ACC off: Manual control!
appears after the ve hicle has been brought to
a standstill by the adaptive cruise control. In
this case you must depress the brake peda l to
prevent the veh icle from rolling. A warn ing
tone sounds as a reminder.

ACC functionality limited
T he message ACC functionality limited ap­
pears when the ACC System does not detect
any moving vehicles up ahead in yo ur lane of
trave l for a longer period of time. During this
time, the distance to moving vehicles in your
lane of travel up ahead is not being ma in­
ta ined . The ACC system is not switched off,
and increased attention to the traffic situation
is absolutely necessary. The following may be
reasons why the message

appears :
- The ACC sensor is d irty . The ACC system is
not react ing, or is not reacting correctly, to
moving vehicles up ahead in your lane of
t ravel.
- There may be very light traffic on and there
is nothing that marks the side of the road
(for examp le, guard ra ils, traffic signs,
trees). As soon as a moving vehicle up ahead
is detected again, ACC becomes active again
and the message disappears.
T he ACC sensor is located be hind the area to

System limitations
General information
Applies to vehicles: with adaptive cruise co ntrol
The radar sensor has limits that the driver
must know to be able to use ACC properly .
The adaptive cruise control works within lim­ its 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 attent ive
to what is happening around you and always
be ready to intervene, if necessary:
-when driving around curves ¢page 125
- when vehicles up front are not in line with
your vehicle ¢ page 126
- when other veh icles are changing lanes
i=> page 126
- when other vehicles are difficult to detect i=>page 126
- when vehicles up ahead are not moving or obstacles are in your travel lane i=>page 126
A WARNING
The radar sensor's function and range can
be reduced by rain, snow and heavy spray.
Moving veh icles up ahead may not be
prompt ly detec ted or may not be detected
a t all.
- Always pay careful att ention to the traf­
fic s ituation and be ready to intervene
and be re ady to take comp lete cont rol
whenever necessary.
