. The ACC system is not switched off, so increased alertness
is required. The following may be reasons for the text message ACC
Functionally limited:
• The ACC sensor is dirty. The ACC system is not reacting, or is not
reacting correctly, to vehicles traveling ahead.
• It is possible that you are driving on a road with very light traffic
without anything at the s ide of the road (e .g . guard rails, traff ic s igns,
trees). As soon as a vehicle is detected by the system again, it returns
t o its contro l range and the text message disappears.
The ACC sensor is located in the r ight front trim grille=>
page 122,

this area should cleaned to restore proper operat ion .
ACC not available
The text message ACC not available appears, for examp le, if the

ersh ip.
ACC sensor blocked !
The text message ACC sensor blocked! appears when the ACC system
can no longer guarantee safe detection of objects. Adaptive cruise
control is turned off. A warning tone sounds as a reminder.
To decide whether it is necessary to switch off the ACC (ACC sensor
blocked
!) or if it is only a temporary condition (ACC Functionally
limited), the system w ill also takes into consideration the outside
temperature and/or the windshield wiper operation .
Th e ACC sensor is d irty or blocked (e.g. leaves, snow).

General information
Some driving situations which affect the function of the
radar sensor are described below.
When driving, the adaptive cru ise contro l is governed by physical and
system-specified limits. Also, under certain circumstances, the ACC
system may react unexpectedly or late from the driver's point of view.
Therefore, a lways be attentive and intervene, if necessary:
• when driving around curves=>
page 134
• when vehicles in front are not in line with your vehicle=> page 134
• when other ve hicles are changing lanes=> page 134
• when other veh icles are difficult to detect=> page 135.
& WARNING
The radar sensor's vision can be reduced by rain, snow and heavy
spray . This can result in vehicles driving ahead being inadequately
detected or , in some circumstances , not detected at all. If neces­
sary, take action yourself!•

Side ass ist uses radar sensors (not vi sible on outside)=> fig. 132 to
help the driver check blind spots , and see what is happen ing in traffic
behind the vehicle=>
page 139, fig. 135.
Signal lights are bu ilt into both outside mirrors
(D => fig . 133 . The
signal ligh t on the left ou tside mirror assists when moving over in to the
left lane and the signal light on the right outs ide mirror assists
when moving over into the right lane.
T he sig nal light comes on to tell you that side assist has detected a
vehicle on that side and that the position of this other vehicle should be taken into acco unt if you were to change lanes . This is called the
inf ormational stage signal =>
page 140. The informationa l stage
signal is designed so that you not ice it only when you are looking in
the o utside m irror.
When you activate the turn s ignal and side assist detects a vehicle in
a notable locat io n, the co rrespo nd ing s ignal on the ou tside m irror
flashes briefly and brightly several times. This is the alert stage

& WARNING
• Improper reliance on the side assist system can cause collisions
and seriou s per sonal injury:
- Never rely only on side assist when changing lanes.
- Alway s check rear view mirrors to make sure that it is safe to
change lanes.
• Side assist cannot detect all vehicles under all condition s­
danger of accident!
• Side a ssist cannot detect vehicle s
in time to alert you when
they approach from behind at very high speed , or fall drop bac;k
very quickly .
• The radar sensor's
vision can be reduced o r entirely blocked by
rain, snow, and heavy spray . Thi s can result in side a ssist not
adequately detecting vehicles o r, in some cases , not detecting
them at all. Always keep an eye on the direction you are traveling
and the relevant area around the vehicle.
• Plea se note that side assi st indi cates there are approaching
veh icles, or vehicles in your blind spot, only after your vehicle has
reached a driving speed of at lea st 19 mph (30 km/h).
• Side assist signal does not work around tight corners (turning
radius le ss than 328 feet or 100 m).
• Side assist is no replacement for the driver's full attention. The
driver alone is respon sible for lane changes and similar driving
maneuvers. Always keep an eye on the direction you are traveling
and the relevant area around the vehicle .

The detection~ page 139, fig. 135 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 covered by the radar sensors .
rn Tips
Side assist does not measure actual lane width. The system assumes
a fixed lane width. Detection in the left and right lanes is based on
this assumed lane width. 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 144. •
Applie s to vehic les: w ith s ide 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 respective mirror .
The signal can light up if you are passed by a vehicle or if you are
passing another vehicle .
If you pass another vehicle slowly (difference 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 will not come on. •
Appli es to vehicles : with si de assist
Informational and alert stage signals
Side ass ist has two signal stages:
• the informational stage signal, and
• the alert stage signal.
Side assist helps you by using the appropr iate signal stage,
depending on whether or not you have activated the turn signal, and
thus have indicated that you are or are not changing lanes.
Informational stage signal
As long as you have not activated the turn signal, s ide assist informs
you of detected vehicles that are reg istered as being in a notable loca ­
tion if you were to change lanes . Whenever the detected vehicle's
difference in speed and distance is registered by side assist as
notable , the signal light on the respective mirror produces muted
illumination.
Th e brightness of the informat ional stage signal is designed not to be
as intense, so that it does not interfere with your view of the road
when you are driving and have no intention of changing lanes. When
you look in the outs ide mirror, you can clearly see the informational
stage signal.
Alert stage signal
When you act ivate the turn s ignal , and side assist has detected a
vehicle in a notable location on that particular side , the signal light on
this side mirror flashes brightly. The repeated brief and bright
flashing of the alert stage signal reminds you to carefully check
traffic to the rear in the outside mirror and over your shoulder, so that
you can safely complete the lane change~

page 145.
rn Tips
The brightness of the signa l light on the outside mirrors can be
adjusted with the MMI*
