System Limitations
Applies to veh icles: with Adaptive C ruise Cont ro l
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=>
page 141.

& WARNING
The radar sensor's function and range can be reduced by rain, snow
and heavy spray. Moving vehicles up ahead may not be promptly
detected or may not be detected at all .
• Alway s pay careful attention to the traffic situation and be
ready to intervene and be ready to take complete control when ­
ever necessary .•

Entering a curve
When entering a curve, the Adaptive cruise control may react to a
vehicle in the next lane and apply the brakes in your vehicle
=>
page 139, fig. 149. The braking action can be overridden by
depressing the accelerator pedal.
Leaving a curve
At the end of very long curves, ACC's predictive lane reading can cause
ACC to react to another vehicle in the next lane and apply the brakes
on your vehicle=>

Aud i Lane assist
Lane assist
Applies to veh icles : w ith lane assist
Description
Lane assist helps you keep your vehicle in your lane.
Lane assist uses a camera to detect lane boundary lines. If the system
detects that your vehicle is about to leave a lane boundary line, the
steering wheel
vibrates to alert the driver. If lane assist detects
boundary lines on both sides o f the veh icle's lane, the system enters
act ive standby mode, which is indicated by t he gree n indicator light
/: on the instrument cluster .
If the system is in active standby mode and the turn signal is acti­
vated before driving over the boundary line , the warning does not
occur sinc e th e system allows for in tention al lane changes.
The system is designed for driving on freeways and expanded high­
ways and th us works only at speeds of 40 mph (65 km/h) or more.
& WARNING
• Lane assist will not keep your vehicle in your lane. The system
only warns the driver when the vehicle is leaving the lane. The
driver is always responsible for keeping the vehicle in the lane.
• The camera is not able to detect all lane boundary lines and in
some cases might also detect lane structures or objects as
boundary lines. This can lead to incorrect warnings or warnings
that fail to go off at all.
• The camera's visibility can be impaired by vehicles ahead of
you, for instance, or by rain, snow, heavy spray or light shining
into the camera lens. This can cause lane assist to fail to detect
boundary lines. •

Not read y: The yellow indicator light shows that the system is
turned on but unable to send a warning. T his can be due to the
following:
• T here are no boundary lines, or there is only one boundary line
present.
• The boundary lines are not detected (e .g . due to snow, dirt, wet
conditions or light shining into the camera lens) .
• More than two boundary lines (such as at const ruct ion sites) are
located in the vehicle's lane .
• T he veh icle's speed is below the speed needed to ac tivate it, which
is about 40 mph (65 km/h) .
• T he lane is narrowe r than about 8
ft . (2.5 m), or wider than about
16 ft. (5 m).
• Th e curve is too sharp.
Note s on the in strum ent clust er displa y
When the lane assist turns off automat ica lly, the instrument cluster
indicator goes out and one of the fo llowing messages appears on the
display :
Aud i lane ass is t not av ailable: Cur rentl y n o sens or v ision
T his message appears when the camera can no longer function
because it cannot detect the boundary lines. This may be due to the
following:
• T he exte rior side of the came ra viewing window =>
page 142,
fig. 157 is covered with dirt or ice. Clean this part of the windsh ield.
• Th e came ra viewing window is fogged up on the inside. In this
case, wait until the fog d isappears before turning lane assist on
again.
• T he system was unable to detect bo undary lines over an extended
period of time due to road co nd it ions (such as snow-cove red lanes) .
Do not turn lane assist on aga in until the lines can be more easily
detected .

lane and the signal light on the right outside mirror assists when
moving over into the right lane.
Th e signal 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 account if you were to change lanes. This is called the
informational stage signal~ page 147. The informational stage
signal is designed so that you notice it only when you are looking in
the outside mirror .
When you activate the turn s ignal and side assist detects a vehicle in
a notab le location, the corresponding signal on the outside mirror
flashes briefly and brightly several times. This is the
alert stage

& WARNING
• Imp roper reliance on the side assist system can cause collisions
and seriou s per sonal injury:
- Never rely only on s ide ass ist when changing lanes.
- Alway s che ck rear view mirror s to m ake sure that it i s safe to
change lanes.
• Side a ssist cannot detect all vehicles under all condition s­
danger of accident!
• Side a ssi st cannot detect vehicle s in time to alert you when
they approach from beh ind at very high speed, or fall drop back
very quickly .
• The radar sen sor's
v is ion can be reduced or entirely blocked by
rain , snow, and heavy spray . This can result in side as sis t not
adequately detecting vehicle s or , in some cases, not detecting
them at a ll. Alway s keep an eye on the dir ection you are traveling
and the rele vant area around the vehicle.
• Please note that side assist indicates there are approaching
vehicles , or vehicles in you r blind spot, only after you r vehicle has
reached a driving speed of at lea st 19 mph (30 km/h).
• Side assist signal doe s not work around t ight corners (turning
radius less 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 change s and s imilar driving
maneuvers. Always keep an eye on the direction you are traveling
and the relevant area around the vehicle.
0 Note
• T o ensure that you do not adversely affe ct s ide as sist , do not block
the area on the rear b umper where the radar sensors are located with
fo reign objects (such as st ic kers or b icycle ra cks).
• Make s ure that the signal light on the o utside mi rror is not
bloc ked by stic ke rs or othe r items.
[I) Tips
• Side ass ist automatica lly deac tivates if it detects that the radar
sensors are blocked=>

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~

@ Informational stage signal lights up
A fast approaching vehicle· in the left-hand lane for example· was
detected by the sensors. A lthough this vehicle is stil l far away, it
should be taken into account if you were to change lanes, due to the
considerable difference in speed. The informational stage signal on

If you activate your turn signal in driving situation@, the signal
br iefly flashes repeatedly . Side assist is alerting you to a veh icle that
you may not have noticed.
[I] Tips
• The faster a vehicle approaches from the rear, the sooner the
signa l on the outs ide mirror lights up. S ide assist will signal, at the
latest, when a detected vehicle enters your "blind spot".
• When vehicles approach very qu ickly, chang ing lanes can be
dangerous even if the s ignal on the outside m irror does not light up. •
