The text message ... (three whi te dots) appears if a setting cannot be
implemented with the operating lever . The following are possib le
reasons :
• If you pull the control lever towards you to resume speed but no
requested speed was set .
• If you push the lever up to increase (or down to reduce) speed
when no speed has been set previously .
• I f 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 functi onal it y limited
The text message ACC fun ctio na lit y lim ited 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
Controls and equip ­
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
react ing correctly, to veh ic les traveling 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 right front trim grille::::>
page 118,
fig. 122 . 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 not available appears , for example, if the
temperature of the brakes is excessive. Adaptive cruise control is
temporarily not availab le . A warning tone sounds as a reminder .
ACC not a vailable !
The text message ACC not ava ila ble! appears in the event of a
malfunction . Adaptive cru ise control is turned off . A warning tone
sounds as a reminder. Have the system inspected by a qua lified
dea lership .
ACC sensor blo cked !
The text message ACC s ensor 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
b locked
!) or if it is only a temporary condition (ACC F unctionally
limited), the system wi ll a lso takes into consideration the outside
temperature and/or the windshield wiper operation.
The ACC senso r is dirty or b locked (e .g . leaves, snow).
The sensor should be cleaned to restore proper sensor function

& WARNING
• Improper reliance on the side assist system can cause colli­
sions and serious personal injury :
- Never rely only on side assist when changing lanes .
- Always che ck rear view mirrors to make sure that it is safe to
change lane s.
• Side assist cannot detect all vehicles under all conditions­
danger of ac cident!
• Side assist cannot detect vehicles in time to alert you when
they approach from behind at very high speed, or f all drop back
very quickly.
• The radar sensor 's
vision can be reduced or entirely blocked by
rain , snow , and heavy spray . This can result in side assist not
adequately detecting vehicles or , in some cases, not dete cting
them at all . Always keep an eye on the direction you are traveling
and the relevant area around the vehicle .
• Please note that side assist indicates there a re approaching
vehicles , or vehicles in your blind spot , only after your vehicle has
reached a driving speed of at least 19 mph (30 km /h).
• Side assist s ignal does not work around tight corners (turning
radius less than 328 feet or 100 m l.
• Side assist is no replacement for the driver's full attention . The
driver alone is responsible for lane changes and similar driving
maneuvers . Always keep an eye on the direction you are traveling
and the relevant area around the vehicle.

d etec tion area
The detection => fig . 147 of the radar sensor detection area is made
up of:
• the approach area (light green area)
0, about 230 feet (70 m)
behind the vehic le, and
• the "blind spot" (dark green areal@.
The radar sensors cover the adjacent left and right lanes. Other
lanes are
not covered by the radar sensors.
[ i ] Tip s
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 trave l lane, it is
possible that vehicles will be detected that are
not in the lane next
t o the lane you are using=>

Operation
Side assist compares the distance and difference in speed of
detected vehic les with the speed of your vehic le. Whenever the
difference in speed a nd distance is registered as notable if you were
to change lanes , a signal 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 slow ly (difference in speed less than 9
mph, or
15 km/h), the signal light wil l come on as soon as the o ther
vehic le is in your b lind spot and is detected by side assist. When the
difference in speed is greater, the signal light will not come on .•
Ap plies to vehi cles : with si de assi st
Informational and alert stage signals
Side assist has two signal stages:
• t he informational stage s igna l, and
• the alert stage signal.
Side assist helps you by using the appropriate signa l stage,
depending on whether or not you have activated the tu rn signal,
and thus have indicated that you are or are not changing lanes .
Infor mation al stage signal
As long as you have not activated the turn signa l, side assist informs
you of detected vehicles that are registered as being in a notable location 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.
The brightness of the informational stage signa l 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. .,
I • •

• ..__A_ u_ d_ i _s _i_d _e_ a_ s_ s _ is_ t __________________________________________________ _
When you look in the outside mirror, you can clearly see the infor­
mational stage signal.
Alert stage signal
When you activate the turn signal, and side assist has detected a
vehicl e 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=>

General information
Side assist has limits and cannot detect vehicles under a ll road and
weather conditions . Please remember system limitat ions and never
re ly on the system, especially when:
• driving through curves=>
page 141,
• lanes are of different widths=> page 142. •
Applies to veh ic les : with s ide ass ist

Side assist cannot detect vehic les in curves with a turning radius of
less than 328 feet (100 ml. .,,
I • •

• .___A_ u_ d_ i_s_ i_ d _e_ a_ s_ s_is _ t __________________________________________________ _
When driving through a curve, it is possible that side assist may
register a vehicle two lanes over, and the signal on the outside
mirror will light up.•

Lane width
Fig. 153 Lanes of a
normal width are in
detection area
Fig. 154 Narrow lanes :
Side assist may detect
vehicles two lanes
away
Side assist's detection area is designed to cover lanes of standard
width to the left and right of your travel lane, depending on whether
you drive in the center of your lane or closer to the edge.
If you drive in narrow lanes, side assist's detection area may also
include other lanes -especially if you tend to drive on the edge of
your lane=> fig. 154. Under these conditions, vehicles can also be detected that are two
lanes away, and side assist then could switch
between the informational and warning stage signals.
When driving in very wide lanes, vehicles in the adjacent lane may
not be detected because they are not inside the detection area. •
Notes
