2013 MERCEDES-BENZ SLK-Class stop start

takes place although the collision fulfills the
criteria for deploying the driver's ai
rbag.
If the front-passenger seat, the seat cover or
the seat cushion are damaged, have the
necessary repai rwork carried out at a
qualified specialist workshop.
Mercedes-Benz recommends that you only
use seat accessories which have been
approved by Mercedes-Benz.
System self-test G
WARNING
If the 0017 PASSENGER AIR BAG OFF
indicator lamp does not illuminate, the system
is not functioning. Consult an authorized
Mercedes-Benz Center before seating a child
on the front-passenger seat. G
WARNING
Never place anything between seat cushion
and child seat (e.g. a pillow), since it reduces
the effectiveness of the OCS. The underside
and rear side child restraint system must be
placed entirely on the seat cushion and the
backrest of the front-passenger seat
backrest.
If necessary, adjust the tilt of the passenger
seat backrest.
An incorrectly mounted child seat could cause
injuries to the child in case of an accident,
instead of increasing protection for the child.
Follow the manufacturer's instructions for
installation of child restraint systems.
The 00030005 indicator lamp lights up:
R if you turn the SmartKey in the ignition lock
to position 1or 2
R if you press the KEYLESS-GO Start/Stop
button once or twice on vehicles with
KEYLESS-GO
R if an adult is seated properly on the front-
passenger seat and the OCS classifies the
occupant as an adult
The 00030005 indicator lamp goes out after
approximately 6seconds. If the seat is not occupied and the OCS
detects that the front-passenger seat is
empty, the 00030005indicator lamp will
continue to light up. The 00030005front-
passenger fron tair bag warning lamp then
stays lit continuously.

Belt warning for the driver and front
passenger Regardless of whether the driver's and front-
passenger seat belts have already been
fastened, the 0011seat belt warning lamp
lights up for six seconds each time the engine
is started. It then goes out if the driver and
the frontp assenger have fastened their seat
belts.
If the driver's seat belt is no tfastened when
the engine is started, an additional warning
tone will sound. The warning tone goes out
after approximately six seconds or once the
driver's seat belt is fastened.
If after six seconds the driver or front
passenger have no tfastened their seat belts
and the doors are closed, the 0011seat belt
warning lamp lights up:
R until the driver's or fron tpassenger's seat
belt is fastened
R if a vehicle speed of 15 mph (25 km/h) is
exceeded, a warning tone also sounds with
increasing intensity for a maximum of
60 seconds or until the driver or front
passenger have fastened their seat belts. If the driver/front passenger unfasten their
seat belt while the vehicle is in motion, the
0011
seat belt warning lamp lights up and a
warning tone sounds again.
The warning tone ceases eve nifthe driver or
front passenger have still not fastened their
seat belt after 60 seconds. The 0011seat belt
warning lamp stops flashing but remains
illuminated.
After the vehicle comes to a standstill, the
warning tone is reactivated and the 0011seat
belt warning lamp flashes again if the vehicle
speed again exceeds 15 mph (25 km/h).
The 0011 seat belt warning lamp only goes
out if:
R both the driver and the front passenger
have fastened their seat belts.
or
R the vehicle is stationary and a door is open.

distribution)
i Observe the "Important safety notes"
section (Y page 59). G
WARNING
If EBD has malfunctioned, the rear wheels can
still lock, e.g. under full braking. This
increases the risk of skidding and an accident.
You should therefore adapt your driving style
to the different handling characteristics. Have
the brake system checked at a qualified
specialist workshop.
Observe information regarding indicator and
warning lamps (Y page 244) as well as
display messages (Y page 214).
EBD monitors and controls the brake
pressure on the rear wheels to improve
driving stability while braking. 64

ADAPTIVE BRAKE
ADAPTIVE BRAKE enhances braking safety
and offers increased braking comfort. In
addition to the braking function, ADAPTIVE

(Y page 177) and hill start assist
(Y page 139). PRE-SAFE
®
Brake
i Observe the "Importan tsafety notes"
sectio n(Ypage 59).
PRE-SAFE ®
Brake is only available in vehicles
with DISTRONIC PLUS.
PRE-SAFE ®
Brake can help you to minimize
the risk of a collision with a vehicle ahead or
reduce the effects of such a collision. If PRE-
SAFE ®
Brake detects a risk of collision, you
will be warned visually and acoustically as
well as by automatic braking. PRE-SAFE ®
Brake cannot preven tacollision withoutyour
intervention.
Starting at a speed of around
20 mph (30 km/h), this function warns you if
you very quickly approach a vehicle in front.
An intermittent warning tone will then sound
and the 000Cdistance warning lamp will light
up in the instrument cluster.
X Brake immediately in orde rto increase the
distance from the vehicle in front.
or
X Take evasive action provided it is safe to do
so.
From a speed of approximately
20 mph (30 km/h), if the driver and front
passenger have fastened their seat belts,
PRE-SAFE ®
Brake can brake the vehicle
automatically at speeds up to approximately
124 mph (200 km/h).
Due to the nature of the system, particularly
complicated driving conditions may cause
unnecessary warnings or the unnecessary
intervention of PRE-SAFE ®
Brake. You can prevent the intervention of the PRE-
SAFE
®
Brake at any time by:
R depressing the accelerator pedal further
R activating kickdown
R releasing the brake pedal.
The braking action of PRE-SAFE ®
Brake is
ended automatically if:
R you maneuver to avoid the obstacle.
R there is no longer any danger of a rear-end
collision.
R there is no longer an obstacle detected in
front of your vehicle.
With the help of the radar sensor system,
PRE-SAFE ®
Brake can detect obstacles that
are in front of your vehicle for an extended
period of time.
At speeds up to approximately
40 mph (70 km/h), PRE-SAFE ®
Brake can
also detect stationary obstacles such as
stopped or parked vehicles.
If you approach an obstacle and PRE-SAFE ®
Brake detects a risk of a collision, the system
will alert you both visually and acoustically. If
you do not brake or take evasive action, the
system will warn you by automatically braking
the vehicle gently. If there is an increased risk
of collision, preventative passenger
protection measures (PRE-SAFE ®
) are
activated (Y page 50).
If a risk of collision remains and you do not
brake, take evasive action or significantly
accelerate, automatic braking may be
performed up to a level of automatic
emergency braking. Automatic emergency
braking is not performed until immediately
prior to an accident that can no longer be
avoided. G
WARNING
PRE-SAFE ®
Brake will initially brake your
vehicle by a partial application of the brakes
if a danger of collision is detected. There may
be a collision unless you also brake.
Automatic emergenc ybraking cannot prevent
a collision. There is a risk of an accident. Driving safety systems
