® Brake can react to stationary
obstacles such as standing or parked vehi-
c le s a t roa d s pe eds of up to ap proxim a tel y
40 mph (70 km/h).

Activating and deactivating: Activate
or deactivate PRE-SAFE
® Brake using
the instrument cluster control system
(
page 298).
After the function has been activated,
indicator : appears on the
left-hand side of the multifunction dis-
play.PRE-SAFE
® Brake does not always clearly
interpret complex traffic situations. If a vi-
sual and/or acoustic warning is issued in
an uncritical driving situation, or if the ve-
hicle brakes lightly, you can interrupt the
PRE-SAFE® Brake maneuver by


pressing down all the way on the accel-
erator or using kickdown


releasing the brake pedal
The PRE-SAFE
® Brake maneuver is termi-
nated immediately when


you avoid the obstacle by evasive
steering


you drive less than 9 mph (15 km/h)


an obstacle can no longer be identified
ahead of you


the system no longer senses the risk of
a collisionAfter a hard collision or damage to the
front of the vehicle from an accident, have
the settings and operation of the radar
sensors checked by an authorized
Mercedes-Benz Center.
Warning!
G
If you do not receive visual or acoustic warn-
ing signals, PRE-SAFE
® Brake has either not
recognized the collision risk, has been deac-
tivated or is malfunctioning. Apply the
brakes yourself to avoid a collision.

PRE-SAFE
® Brake will remain passive while
DISTRONIC Plus* is switched on (

If your vehicle is equipped with DISTRONIC
Plus*, BAS Plus*, or Park Assist* it is
equipped with a radar sensor system
which you can switch on and off.

registered in Canada, you must switch off
the radar sensor system. Canadian law
does not permit the use of the radar sensor
system for vehicles from outside of Cana-
da. When you switch off the radar sensor
system, the following functions are

383 Controls in detail
Mirrors
Auto-dimming rear view mirrors
The reflection brightness of the exterior
rear view mirror on the driver’s side and
the interior rear view mirror will respond
automatically to glare when

the ignition is switched on
(page 365)
and


incoming light from headlamps falls on
the sensor in the interior rear view
mirror
The interior rear view mirror will not react if


reverse gear R is engaged
and


the interior lighting is turned on
Warning!
G
The auto-dimming function does not react if
incoming light is not aimed directly at the
sensors in the interior rear view mirror.
The interior rear view mirror and the exterior
rear view mirror on the driver’s side do not
react, for example, if the rear window sun-
shade is in raised position.
Light hitting the mirror(s) at certain angles
(incident light) could blind you. As a result,
you may not be able to observe traffic con-
ditions and could cause an accident.
Warning!
G
Exercise care when using the passen-
ger-side exterior rear view mirror. The mirror
surface is convex (outwardly curved surface
for a wider field of view). Objects in mirror
are closer than they appear. Check your in-
side rear view mirror or glance over your
shoulder before changing lanes.

!
If the windshield wipers leave smears on the
windshield after the car has been driven through
an automatic car wash, then wax or other resi-
due is on the windshield. Shortly after washing
the car in an automatic car wash, clean the wind-
shield with windshield washer fluid
(
page 401).
!
Do not operate the wipers when the wind-
shield is dry. Dust that accumulates on a wind-
shield might scratch the glass and/or damage
the wiper blades when wiping occurs on a dry
windshield. If it is necessary to operate the wip-
ers in dry weather conditions, always operate
the wipers with windshield washer fluid
(
page 401).
!
If anything blocks the windshield wipers
(leaves, snow, etc.), switch them off immediate-
ly.


For safety reasons, stop the vehicle in a safe
location,

turn off the engine by turning the
SmartKey to position0 and withdraw
SmartKey from starter switch
or


turn off the engine by pressing the
KEYLESS-GO* start/stop button
(page 366) and open the driver’s door
(with the driver’s door open, starter
switch is in position0, same as with
SmartKey removed from starter switch)
before attempting to remove any blockage.


Remove blockage.


Turn the windshield wipers on again.If the windshield wipers fail to function at all with
the combination switch in position u,


set the combination switch to the next high-
er wiper speed


have the windshield wipers checked at the
nearest authorized Mercedes-Benz Center

401 Controls in detail
Windshield wipers
Intermittent wiping
Only switch on intermittent wiping under
wet weather conditions or in the presence
of precipitation.

Turn the combination switch to posi-
tion U or V.
The wipers move across the wind-
shield. Afterward, the wiping intervals
are determined by the wetness of the
windshield.
After the initial wipe, pauses between
wipes are automatically controlled by the
rain sensor.
Single wipe
Press the combination switch briefly in
the direction of arrow2 (
page 400)
to the resistance point.
The windshield wipers wipe one time
without washer fluid.
Wiping with windshield washer fluid
Press the combination switch in the di-
rection of arrow2 (
page 400) past
the resistance point.
The windshield wiper operates with
washer fluid.
For information on filling up the washer
reservoir, see “Windshield washer system
and headlamp cleaning system”
(
page 560).
i
When the windshield wipers are switched on
and you brake the vehicle to a stop, the wipers
operate more slowly.
!
Do not leave windshield wipers on an inter-
mittent setting when the vehicle is taken to an
automatic car wash or during windshield clean-
ing. Wipers will operate in the presence of water
sprayed on the windshield, and windshield wip-
ers may be damaged as a result.
!
If you have set intermittent wiping, dirt on
the surface of the rain sensor or optical effects
may cause the windshield wipers to wipe in an
undesired fashion. This could then damage the
windshield wiper blades or scratch the windows.
You should therefore switch off the windshield
wipers when weather conditions are dry.
i
Intermittent wiping is interrupted when the
vehicle is at a standstill and a door is opened.
This protects persons getting into or out of the
vehicle from being sprayed.
Intermittent wiping will be continued when


both doors are closed and the automatic
transmission is set to positionD orR
or


the wiper setting is changed using the com-
bination switch
i
To prevent smears on the windshield or
noisy/chattering wiper blades, wipe with wind-
shield washer fluid every now and then even
when it is raining.
