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=>
page 139, fig. 150. The braking action can be over­
ridden by depressing the accelerator pedal. •

Some vehicles moving up ahead in your lane of travel are difficult to
detect, for example two-wheeled vehicles, vehicles with high ground
clearance, loads sticking out the back. Vehicles like this are often
detected late or in some situations not at all. •

help the driver check blind spots, and see what is happening in traffic

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
signal ~

& 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=>
page 152. The indicator light on the button
goes out.
• Th e area on the bumper w he re the radar sensors are located must
c ons istent ly rema in free of snow, i ce, a nd he avy soiling so that s ide
assist can function properly. Follow the add itiona l notes on
=>page 1 5 2.

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. •

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

• 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

• 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. •

Safety tips
The s ide assist detection may be limited when driving aro und narrow
s tr eet corners, on hilly st ree ts, an d un der poo r wea ther condit ions. It is possib
le that the radar sensors may also detect other objects,
s uch a s high or s taggere d guardrails.
Side assis t does not measure ac tual lane wid th . The system assumes
a fixed la ne w idth . Detection in the left and rig ht lanes is based on
th is assu m ed lane w id th . W hen drivi ng on nar row ro ads or w hen
driving to the left or r ight of the cente r of a t ravel lane, it is possib le
th at vehicles will be de te ct ed tha t are

you are us ing.
& WARNING
• Improper reliance on the side assist system can cause collisions
and serious personal injury:
-Never rely only on s ide assist when changing lanes.
- Always check rear view mirrors to make sure that it is safe to
change lanes.
• Side assist cannot detect all vehicles under all conditions­
danger of accident!
• Side assist cannot detect vehicles in time to alert you when
they approach from behind at very high speed , or fall 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 detecting
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 are 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 signal does not work around tight corners (turning
radius less than 328 feet, or 100 m) .
• Side assist is no replacement for the driver's full attention . The
driv er 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 .
