Blind Spot AssistandActive Blind Spot
Assi st
Function of Blind Spot Assist and Active
Blind Spot Assi st
Blind Spot Assist uses two lateral,rear-facing
ra dar sensors tomonitor the area up to130ft
(40 m) behind your vehicle and 10ft(3 m)
directly next to yourvehicle.
If a vehicle is de tected at speeds ab ove appr ox‐
imately 8 mph (12 km/h) and this vehicle subse‐
qu ent lyenters the monitoring range di rectly next
to yo urvehicle, thewa rning lamp in the outside
mir ror lights up red.
If a vehicle is de tected close to yourvehicle in
th e lateral monitoring range and youswit chon
th e turn signal indicator in the cor responding
direction, a warning tone sounds once. The red
wa rning lamp in the outside mir rorflashes. If the
turn signal indica torre mains on, all other de tec‐
te dve hicles are indicated only bytheflashing of
th ere dwa rning lamp.
If yo uove rtake a vehicle quickl y,no warning is
given.
0071 WARNING Risk of accident despite Blind
Spot Assist
Blind Spot Assist does notreact tovehicles
approaching and overtaking you at a greatly
di fferent speed.
As a result, Blind Spot Assist cannot warn
drivers in this situation.
00BBAlw ays pay careful attention tothe traf‐
fi c situation and maintain a safe dis‐
ta nce at the side of theve hicle.
Blind Spot Assist and Active Blind Spot Assi st
are only aids. They may failto detect some vehi‐
cles and are no substitute for attentive driving.
Alw ays ensure that there is suf ficient dist anceto
th e side forot her road users and obs tacles.
Sy stem limitations
The sy stem may be limited in thefo llowing situa‐
tions:
Rth e sensors are dirty or co vered
Rpoor visibility, e.g. due tofog, heavy rain,
snow or spr ay
Rnarrow vehicles, e.g. bicycles, are within the
monitoring range
Wa rnings may be issued in er ror when driving
close tocrash barr iers or similar solid lane bor‐
ders. Warnings may be inter rupte d when driving
alongside long vehicles, e.g. truc ks,fo r a pro‐
longed time.
Blind Spot Assist is not operational when reve rse
ge ar is engaged.
Fu nction of braking applications (Active
Blind Spot Assist)
If Ac tive Blind Spot Assi stdetects a risk of a side
impact in the monitoring range, a cours e-cor‐
re cting brake application is car ried out. This is
designed tohelp youav oid a collision.
The course-cor recting brake application is availa‐
ble in the speed range between appr oximately
20 mph (30 km/h) and 125mp h (200 km/h).

DANG ER Risk of accident due toincor‐
re ct tire pressure
Every tire, including the spare (if pr ovided),
should be checked when cold at least once a
month and inflated tothe pressure recom‐
mended bytheve hicle manufacturer (see
Ti re and Loading Info rmation placard on the
B-pillar on the driver ’sside or the tire pres‐
sure label on the inside of the fuel filler flap
of your vehicle). If your vehicle has tires of a
dif fere nt size than the size indicated on the
Ti re and Loading Info rmation placard or the
tire pressure table, you need todeterm ine
th e proper tire pressure forth ose tires.
As an added saf etyfe ature, your vehicle has
been equipped with a tire pressure monitor‐
ing sy stem (TPMS) that illuminates a low tire
pressure indicator lamp when one or more of
yo ur tires are signif icantly underinflated.
Ac cording ly, if the low tire pressure indicator
lamp lights up, you should stop and check
yo ur tires as soon as possible, and inflate
th em tothe proper pressure. Driving on a
significant lyunderinflated tire causes the tire
to ov erheat and can lead totire failure.
Un derinflation also increases fuel consump‐
tion and reduces tire tread life, and may
af fect theve hicle's handling and braking abil‐
ity. Please no tethat the TPMS is not a substi‐
tute for proper tire maintenance, and it is the
driver's responsibility tomaintain cor rect tire
pressure, even if underinflation has not
re ached the le velto trig ger illumination of
th e TPMS low tire pressure indicator lamp.
Yo ur vehicle has also been equipped with a
TPMS malfunction indicator toindicate whenthe sy stem is not operating proper ly. The
TPMS malfunction indica tor is combined with
th e low tire pressure indicator lamp. When
th e sy stem de tects a malfunction, the indica‐
to r lamp will flash for app roxima tely a minute
and then remain continuously illumina ted.
This sequence will continue upon subsequent
ve hicle start-ups as long as the malfunction
ex ists.
When the malfunction indicator is illumina‐
te d, the sy stem may not be able todetect or
signal low tire pressure as intended. TPMS
malfunctions may occur for a variet yof rea‐
sons, including the ins tallation of incompati‐
ble replacement or alternate tires or wheels
on theve hicle that pr eventthe TPMS from
functioning properly.
Alw aysch eck the TPMS malfunction warning
lamp af terre placing one or more tires or
wheels on your vehicle toensure that the
re placement or alternate tires and wheels
allow the TPMS tocontinue tofunction prop‐
erly.
