Fig . 88 S ig n al l ight on the outside m irro r - drive r's side
Side assist uses radar sensors (not visib le on
outside)
c::> fig. 87 to help the driver check
blind spots, and see what is happening in traf
f ic beh ind the veh icle
c::> page 88, fig. 89 .
Signal lights are built into both outside mir
rors <=>
fig. 88. The signal light on the left out
side mirror assists when moving over into the left lane and the signal light on the right out
side m irror assists when moving over into the
right lane .
The 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 yo u were to change
lanes. This is called the
informati onal stag e
s ignal
c::> page 89. The informational stage
signal is designed so that you notice it only
when yo u are look ing in the outside mirro r.

A WARNING
-
- Improper reliance on the side assist sys-
tem can cause collisio ns and serious per
sonal injury:
- Never rely on ly on s ide assist whe n
changing lanes.
- Always check rear view mir rors to make
sure that it is safe to change lanes.
- Side assist cannot detect all veh icles un
de r al l conditions- danger of accident!
- Side assist cannot detect vehicles in time
to a le rt you when they approa ch from
behind a t very high speed, or fall drop
back very q uickly.
- The radar sensor's
vision can be red uced
or entire ly blocked by rain, snow, and
heavy spray . This can resu lt in side assis t
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 s ide assist indicates
there are approac hing vehicles, or vehi
cles in your blind spot, on ly afte r you r ve
hicle has reach ed a driv ing speed of at
least 19 mph (30 km/h).

- Side assist signal does not work around
t ight corners (turning radius less than
328 feet or 100 m).
- Side assist is no rep lacement for the driv
er's full attent ion. The dr iver alone is re
sponsible for lane changes and similar dr iv ing maneuvers . Always keep an eye
on the di rection yo u are traveling and the
relevant area around the vehicle.
(D Note
- To ensure that you do not adversely af
fect side assist, do not block the area on
the rear bumper whe re the radar sensors
are located with foreign objects (such as
stickers o r bicy cle racks).
- Make sure that the signa l light on the
outside m irror is not blo cked by st ickers
or other items.
@ Tips
- Side assist a utomat ica lly deactivates if it
detects that the radar sensors a re
blocked E} page 93. The ind icator light
on the bu tton goes out.
- The area on the bumper where the radar
sensors are located must consis tently re
main free of snow, ice, and heavy soiling
so that side assist can function properly .
Fo llow the additional notes on
c> page 93.
-Additional tinting on the front side win
dows can make it harder to see and cor
rectly understand the signa l light on the
outside mirror.

Sensor detection area
Applies to veh icles: w ith side assist
F ig. 89 Schemat ic ill ust rat ion : Sensor detect ion a rea
The detection c> fig. 89 of the radar sensor de
tection area is made up of:
- the approach area (light red area)
(D , about
230 feet (70 m) behind the vehicle, and
- the "b lind spot" (dark red area)@.
T he rada r sensors cover the adjace nt left and
right lanes. Other lanes a re
not covered by the
radar sensors.
(0 Tips
Side assist does not measure a ctual lane
wid th. The system assumes a fixe d lane
width. Detection in the left and right lanes
is based on this assumed lane width .
When driv ing 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 us ing

Operation
Applies to veh icles: w ith s ide assist
S ide assist compares t he d istance and diffe r
ence in speed of detected vehicles wi th the
speed of your vehi cle. Wheneve r the d iffe r
ence in speed and distance is registered as no
tab le if you were to change lanes, a signal
li ght appears on the respective mirror.
T he signa l can ligh t up if yo u are passed by a
vehicle or if you are passing another vehicle.
If you pass another vehi cle slowly (difference
in speed less than 9 mph, o r 15 km/h), the ..,.
Page 91 of 298

signal light will come on as soon as the other
vehicle is in your blind spot and is detected by
side assist. When the difference in speed is
greater, the signa l light will not come on.
Informational and alert stage signals
App lies to vehicles: with side assist
Side assis t has two s ignal stages:
- the informationa l stage signal, and
- the a le rt stage signa l.
Side assist he lps you by usi ng the approp riate
signal s tage, depending on whether or not
you have activ ated the tu rn signal, and thus
have indicated that you are or are not chang
ing lanes .
Informational stage signal
As long as you have not a ctivated the tu rn sig
n al , side a ssis t inf orms you of detec ted vehi
cles th at are registered as being in a notable
l ocation if you were to change lanes. Whenev
er the detected vehicle's difference i n speed
and d istance is registered by side assist as no
table, the signal lig ht on the respective m irror
prod uces muted illuminat ion.
The brightness of the informat io na l stage sig
na l is designed not to be as intense, so that it
does not interfere wit h your view of the road
when you are driving and have no intention of
changing lanes. When you look in the o utside
mirror, you can clear ly see the info rmat iona l
stage signal.
Alert stage signal
When you activate the turn signa l, and side
assist has detec ted a vehicle i n a notable loca
tion o n that particular side, the s ignal l ight on
this sid e mirro r flashes b right ly . The repeated
b rie f and bright flashing of the alert stage
signal re minds yo u to carefully check tr aff ic to
the rear in the o utside mirror and ove r your
shoulder, so that yo u can safe ly complete the
l ane change
