Limited braking e.ect on salt-treated
roads:
R a layer of salt on the brake disks or brakepads
can increase braking distances considerabl y,
or braking may happen on only one side
R maintain an especially lar gesafe dis tance to
th eve hicle in front
To remo vethe la yer of salt:
R apply the brakes from time totime, paying
attention totra1c conditions
R careful lydepress the brake pedal at the end of
a journey and aTer the start of a new journey

Until then, compensate forth ere duced braking

mends that you only ha vebrakepads and brake
disks which are appr ovedby Mercedes-Benz instal-
led on your vehicle.
Other brake disks or brakepads may compromise

In poor road and weather conditions, the trailer

R Situation-dependent brake forc e boosting Ac
tive Brake Assist can help youto minimise the
ri sk of a collision with vehicles, cyclists or pedes-

If Ac tive Brake Assist has de tected a risk of colli-
sion, a warning tone sounds and theL warning
lamp lights up in the instrument cluster.
If yo u do not react tothewa rning, autonomous
braking can be initiated in critical situations. In
especially critical situations, Active Brake Assist
can initiate autonomous braking directl y.In this
case, thewa rning lamp and warning tone are acti-
va ted simultaneously with the braking application.
If yo u apply the brake yourself in a situation de tec-
te d as critical byActive Brake Assist, or app lythe
brake during autonomous braking, situation-
dependent brake forc e boosting occurs. The brake
pressure increases up tomaximum full-s top brak-

Ac tive Parking Assist is an electronic parking assis-
ta nce system which automatically locates and
measures parking spaces on bo thsides of the
ve hicle when you are driving forw ards up to a
speed of appr oximately 35 km/h.
If all requ irements are met, theÇ display
appears in the inst rument cluster displa y.The sys-
te m then independently locates and measures par-
allel and perpendicular parking spaces on bo th
sides of theve hicle.
When Active Parking Assist has de tected parking
spaces, theÈ display appears in the inst ru-
ment cluster displa y.The ar rows show on which
side of thero ad free parking spaces are located.
Ac tive Parking Assist displa ysparking spaces on
th e co-driver side as standard. The parking spaces
on the driver's side are only displa yed if you oper-
ate the turn signal on the driver's side. When par k-
ing on the driver's side, you must operate the turn
signal until you ha vestar ted active parking assis-
ta nce bypressing thea steering-wheel button.
Ac tive Parking Assist can assist you with an active
steering inter vention and brake application during
parking and exiting the parking space. The active brake application is dependent on
the countr y-spe-
ci/c version of theve hicle. On vehicles with man-
ual transmission, active parking assis tance is limi-
