Important safety notes G
WARNING
If the rear seat backrests are not locked, they
could fold forward sinthe event of an acci-
dent, heavy braking or sudden changes of
direction. As aresult, child restraint systems
cannot perform their intended protective
function. Rears eat backrests that are not
locked can also cause additional injuries, e.g. in the event of an accident. This poses an
increased risk of injury or even fatal injury.
Alwaysl ock rear seat backrests after fitting a
Top Tether belt. Observe the lock verification indicator.
If the rear seat backrest is not engaged and
locked, this willbes hown in the multifunction
display in the instrument cluster. Awarning tone
also sounds.

WARNING
The distance warning function does not react:
R to people or animals
R to oncoming vehicles
R to crossing traffic
R when cornering
Thus ,the distance warning function cannot
provid eawarning in all critical situations.
There is arisk of an accident.
Always pay carefu lattention to the traffic sit-
uation and be read ytobrake. G
WARNING
The distance warning function cannot always
clearly identify objects and comple xtraffic
situations.
In such cases, the distance warning function
may:
R give an unnecessary warning
R not give awarning
There is arisk of an accident.
Always pay carefu lattention to the traffic sit-
uation; do not rely on the distance warning
function alone.
Function The distance warning function issues awarning
at speeds:
R of approximately 30 km/h or more, if, over
severa lseconds, the distance maintained to
the vehicl etravelling in front is insufficient.
The · distance warning lamp then lights
up in the instrument cluster.
R of approximately 7km/h or more, if you rap-
idlya pproach avehicl einf ront. An intermit-
tent warning tone willt hen sound,and the
· distance warning lamp willl ight up in the
instrument cluster.
X Brake immediatel yinorder to increas ethe
distance from the vehicl einfront.
or
X Take evasive action provided it is safe to do
so.
Due to the nature of the system, particularly
complicated but non-critical driving conditions
may alsoc ausethe system to display awarning. With the help of the rada
rsensor system, the
distance warning function can detect obstacles
that are in the path of yourv ehiclefor an exten-
ded period of time.
Up to aspee dofa pproximatel y70k m/h, the
distance warning function can alsor eact to sta-
tionary obstacles, such as stoppe dorparked
vehicles.
Autonomous braking function If the drive
rdoes not react to the distance warn-
ing signa linacritical situation, COLLISION PRE-
VENTION ASSIST PLUS can assist with the
autonomous braking function.
The autonomous braking function:
R gives the drive rmore time to react to critical
driving situations
R can help the drive rtoavoidana ccident or
R reduces the effects of an accident
Vehicles without DISTRONIC PLUS: the
autonomous braking function is available in the
following spee dranges:
R 7-1 05 km/h for moving objects
R 7-50k m/h for stationary objects
Vehicles with DISTRONIC PLUS: the autono-
mous braking function is available in the follow-
ing spee dranges:
R 7-2 00 km/h for moving objects
R 7-50k m/h for stationary objects
Due to the nature of the system, complicated
but non-critical driving situations may also
caus ethe autonomous braking function to inter-
vene.
If the autonomous braking function demands
particularl yhigh braking force, preventative
passenger protection measures (PRE-SAFE ®
)
are activated simultaneously (Y page54).

Crosswind Assist General notes
Strong crosswind gusts can impair the road-
holding of yourv ehicle when driving straight
ahead. The crosswind driving assistance func-
tion integrated in ESP ®
noticeably reduces
these impairments.
Depending on the direction and intensity of the
side wind, ESP ®
is activated automatically.
ESP ®
intervenes with stabilising braking to
assisty ou in keeping the vehicle in the lane.
Crosswind Assist is active at vehicle speeds
above 80 km/h when driving straight aheador
cornering gently.
Important safety notes Crosswind Assist does not work if ESP ®

Observe the "Important safety notes" sec-
tion (Y page 66). G
WARNING
If EBD is malfunctioning, the rear wheelsc an
lock, e.g. under full braking. This increases the risk of skidding and an accident.
You shouldt herefore adapt yourd riving style
to the different handling characteristics. Have the brake system checked at
aqualifieds pe-
cialist workshop.
