2016 MERCEDES-BENZ SL ROADSTER park assist

The driver is not warned before the intervention
of PRE-SAFE ®
PLUS.
PRE-SAFE ®
PLUS does not intervene when
reversing.
When driving, or when parking or exiting a park- ing space with assistance from Active Parking
Assist, PRE-SAFE ®
PLUS will not apply the
brakes.
Function PRE-SAFE
®
PLUS intervenes in certain situa-
tions if the radar sensor system detects an
imminent head-on or rear-end collision.
PRE-SAFE ®
PLUS takes the following measures
depending on the hazardous situation detected:
R if the radar sensor system detects that a
head-on collision is imminent, the seat belts
are pre-tensioned
R if the radar sensor system detects that a rear-
end collision is imminent:
- the rear hazard warning lamps are activa-
ted and flash at a higher frequency
- the brake pressure is increased if the driver
applies the brakes when the vehicle is sta-
tionary
- the seat belts are pre-tensioned
The PRE-SAFE ®
PLUS braking application is can-
celled:
R if the accelerator pedal is depressed when a
gear is engaged
R if the risk of a collision passes or is no longer
detected
R if Distance Pilot DISTRONIC indicates an
intention to pull away
If the hazardous situation passes without result- ing in an accident, the original settings are
restored. Automatic measures after an acci-
dent
Immediately after an accident, the following
measures may be implemented, depending on
the type and severity of the impact: R the hazard warning lamps are activated
R the emergency lighting is activated
R the vehicle doors are unlocked
R the front side windows are lowered R
the electrically adjustable steering wheel is
raised
R the engine is switched off and the fuel supply
is cut off
R vehicles with the Mercedes-Benz emergency
call system: automatic emergency call Children in the vehicle

Keep the brake pedal depressed firmly until
the emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will function as usual once you
release the brake pedal. BAS is deactivated. Brake Assist with cross-traffic func-
tion
General notes Brake Assist with cross-traffic function can help
you to minimise the risk of a collision with a
vehicle or a pedestrian and reduce the effects of such a collision. If Brake Assist with cross-trafficfunction detects a danger of collision, you are
assisted when braking.
i Observe the "Important safety notes" sec-
tion (Y page 62).
Brake Assist with cross-traffic function is only
available in vehicles with the Driving Assistance
package.
For Brake Assist with cross-traffic function to
assist you when driving, the radar sensor system and the camera system must be operational.
The sensor system and camera system help
Brake Assist with cross-traffic function detect
obstacles:
R that are in the path of your vehicle for an
extended period of time
R that cross the path of your vehicle
In addition, pedestrians in the path of your vehi-
cle can be detected.
Brake Assist with cross-traffic function detects
pedestrians using typical characteristics such
as body contours and the posture of a person
standing upright.
If the radar sensor system or the camera system
is malfunctioning, Brake Assist with cross-traffic function is restricted or no longer available. The
brake system is still available with complete
brake boosting effect and BAS.
i Observe the restrictions described in the
"Important safety notes" section
(Y page 63). Important safety notes G
WARNING
Brake Assist with cross-traffic function can-
not always clearly identify objects and com-
plex traffic situations.
In such cases, the Brake Assist with cross-
traffic function might:
R intervene unnecessarily
R not intervene
There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation and be ready to brake. Terminate the
intervention in a non-critical driving situation. G
WARNING
Brake Assist with cross-traffic function can-
not always clearly identify people, particularly if they are moving. Brake Assist with cross-
traffic function cannot intervene in these
cases. There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation and be ready to brake. G
WARNING
Brake Assist with cross-traffic function does
not react:
R to small people, e.g. children
R to animals
R to oncoming vehicles
R when cornering
As a result, Brake Assist with cross-traffic
function may not intervene in all critical con-
ditions. There is a risk of an accident.
Always pay careful attention to the traffic sit- uation and be ready to brake.
In the event of snowfall or heavy rain, detection can be impaired.
Detection by the radar sensor system is also
impaired in the event of:
R dirt on the sensors or obscured sensors
R interference by other radar sources
R strong radar reflections, for example, in multi-
storey car parks Driving safety systems
63Safety Z

R
a narrow vehicle travelling in front, e.g. a
motorcycle
R a vehicle travelling in front on a different line
R vehicles quickly moving into the radar sensor
system detection range
Detection by the camera system is also impaired
in the event of:
R dirt on the camera or if the camera is covered
R glare on the camera system, e.g. from the sun
being low in the sky
R darkness
R if:
- pedestrians move quickly, e.g. into the path
of the vehicle
- the camera system no longer detects a
pedestrian as a person due to special cloth- ing or other objects
- a pedestrian is concealed by other objects
- the typical outline of a person is not distin-
guishable from the background
Following damage to the front end of the vehicle, have the radar sensor settings and operation
checked at a qualified specialist workshop. This
also applies to collisions at slow speeds where
there is no visible damage to the front of the
vehicle.
Following damage to the windscreen, have the
configuration and operation of the camera sys-
tem checked at a qualified specialist workshop.
Function To avoid a collision, Brake Assist with cross-
traffic function calculates the brake force nec-
essary if:
R you approach an obstacle and
R Brake Assist with cross-traffic function has
detected a risk of collision
When driving at a speed under 30 km/h: if
you depress the brake pedal, Brake Assist with
cross-traffic function is activated. Braking assis-
tance from Brake Assist with cross-traffic func-
tion is carried out at the last possible moment.
When driving at a speed above 30 km/h: if
you depress the brake pedal sharply, Brake
Assist with cross-traffic function automatically
increases the brake pressure to a degree suited to the traffic situation.
Brake Assist with cross-traffic function providesbraking assistance in hazardous situations with vehicles in front within a speed range between
7 km/h and 250 km/h.
Up to a speed of approximately 70 km/h, Brake
Assist with cross-traffic function may react to:
R stationary objects in the path of your vehicle,
e.g. stopped or parked vehicles
R pedestrians in the path of your vehicle
R obstacles crossing your path, which move in
the detection range of the sensors and are
detected
i If Brake Assist with cross-traffic function
requires a particularly high braking force, pre-
ventative passenger protection measures
(PRE-SAFE ®
) are activated at the same time
(Y page 53).
X Keep the brake pedal depressed until the
emergency braking situation is over.
ABS prevents the wheels from locking.
Brake Assist with cross-traffic function is deac-
tivated and the brakes function as usual again if:
R you release the brake pedal
R there is no longer a risk of collision
R no obstacle is detected in front of your vehicle
R you depress the accelerator pedal
R you activate kickdown Active Brake Assist
General notes i
Observe the "Important safety notes" sec-
tion (Y page 62).
Active Brake Assist consists of a distance warn-
ing function with an autonomous braking func-
tion and Adaptive Brake Assist.
Active Brake Assist can help you to minimise the
risk of a collision with the vehicle in front or
reduce the effects of such a collision.
If Active Brake Assist detects that there is a risk of collision, you will be warned visually and
acoustically. If you do not react to the visual and
audible collision warning, autonomous braking
can be initiated in critical situations. If you apply
the brake yourself in a critical situation, Adap-
tive Brake Assist of the Active Brake Assist sys- tem supports you. 64
Driving safety systemsSafety

Important safety notes
In particular, the detection of obstacles can be
impaired in the case of:
R dirt on the sensors or obscured sensors
R snow or heavy rain
R interference by other radar sources
R strong radar reflections, for example, in multi-
storey car parks
R a narrow vehicle travelling in front, e.g. a
motorcycle
R a vehicle travelling in front on a different line
R new vehicles or after servicing is carried out
on the Active Brake Assist system
Observe the important safety notes in the
"Running-in notes" section (Y page 131).
Following damage to the front end of the vehicle,
have the configuration and operation of the
radar sensor checked at a qualified specialist
workshop. This also applies to collisions at slow speeds where there is no visible damage to thefront of the vehicle.
Activating/deactivating Active Brake Assist is automatically active after
switching on the ignition.
You can activate or deactivate Active Brake
Assist using the on-board computer
(Y page 207). When deactivated, the distance
warning function and the autonomous braking
function are also deactivated.
If Active Brake Assist is deactivated, the æ
symbol appears in the assistance graphic dis-
play.
Distance warning function General notes
The distance warning function can help you to
minimise the risk of a collision with the vehicle in
front or reduce the effects of such a collision. If the distance warning function detects that there
is a risk of a collision, you will be warned visually
and acoustically.
Important safety notes
i Observe the "Important safety notes" sec-
tion for driving safety systems (Y page 62). G
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
provide a warning in all critical situations.
There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation and be ready to brake. G
WARNING
The distance warning function cannot always
clearly identify objects and complex traffic
situations.
In such cases, the distance warning function
may:
R give an unnecessary warning
R not give a warning
There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation; do not rely on the distance warning
function alone.
Function The distance warning function issues a warning at speeds:
R of approximately 30 km/h or more, if, over
several seconds, the distance maintained to
the vehicle travelling in front is insufficient.
The · distance warning lamp then lights
up in the instrument cluster.
R of approximately 7 km/h or more, if you rap-
idly approach a vehicle in front. An intermit-
tent warning tone will then sound, and the
· distance warning lamp will light up in the
instrument cluster.
X Brake immediately in order to increase the
distance from the vehicle in front.
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 also cause the system to display a warning. Driving safety systems
65Safety Z

With the help of the radar sensor system, the
distance warning function can detect obstacles
that are in the path of your vehicle for an exten-
ded period of time.
Up to a speed of approximately 70 km/h, the
distance warning function can also react to sta-
tionary obstacles, such as stopped or parked
vehicles.
Autonomous braking function If the driver does not react to the distance warn-
ing signal in a critical situation, Active Brake
Assist can assist with the autonomous braking
function.
If the autonomous braking function demands
particularly high braking force, preventative
passenger protection measures (PRE-SAFE ®
)
are activated simultaneously.
The autonomous braking function is available in
the following speed ranges:
R 7 - 105 km/h for moving objects
R 7 - 50 km/h for stationary objects
Due to the nature of the system, complicated
but non-critical driving conditions may also
cause the autonomous braking function to inter- vene.
If the autonomous braking function demands a
particularly high braking force, preventative
passenger protection measures (PRE-SAFE ®
)
are activated simultaneously (Y page 53).
Adaptive Brake Assist General notes
i Observe the "Important safety notes" sec-
tion (Y page 62).
With the help of Adaptive Brake Assist, the dis-
tance warning signal can detect obstacles that
are in the path of your vehicle for an extended
period of time.
If Adaptive Brake Assist detects a risk of a col-
lision with the vehicle in front, it calculates the
braking force necessary to avoid a collision. If
you apply the brakes forcefully, Adaptive Brake
Assist will automatically increase the braking
force to a level suitable for the traffic conditions.
Adaptive Brake Assist provides braking assis-
tance in hazardous situations at speeds above
7 km/h. It uses radar sensor technology to
assess the traffic situation. Up to a speed of approximately 250 km/h,
Adaptive Brake Assist is capable of reacting to
moving objects that have already been detected
as such at least once over the period of obser-
vation.
Up to a speed of approximately 70 km/h, Adap-
tive Brake Assist reacts to stationary obstacles.
If Adaptive Brake Assist demands a particularly
high braking force, preventative passenger pro-
tection measures (PRE-SAFE ®
) are activated
simultaneously (Y page 53).
X Keep the brake pedal depressed until the
emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will work normally again if: R you release the brake pedal
R there is no longer any danger of a collision
R no obstacle is detected in front of your vehicle
Adaptive Brake Assist is then deactivated.

Upshifts take place at higher engine speeds
after a cold start. This helps the catalytic con-
verter to reach its operating temperature
more quickly.
Information on automatically releasing the elec- trical parking brake (Y page 155).
Hill start assist Hill start assist helps you when pulling away for-
wards or in reverse on an uphill gradient. It holds the vehicle for a short time after you have
removed your foot from the brake pedal. This
gives you enough time to move your foot from
the brake pedal to the accelerator pedal and
depress it before the vehicle begins to roll. G
WARNING
After a while, hill start assist no longer holds
the vehicle and it may roll away. There is a risk of an accident and injury.
Therefore, quickly move your foot from the
brake pedal to the accelerator pedal. Never
leave the vehicle when it is held by hill start
assist.
Hill start assist is not active if:
R you are pulling away on a level road or a
downhill gradient
R the transmission is in position N
R the electric parking brake is applied

Introduction The ECO start/stop function switches the
engine off automatically if the vehicle is stopped
under certain conditions.
When pulling away again, the engine starts auto-
matically. The ECO start/stop function thereby
helps you to reduce the fuel consumption and
emissions of your vehicle.
Important safety notes G
WARNING
If the engine is switched off automatically and you exit the vehicle, the engine is restarted automatically. The vehicle may begin moving.
There is a risk of accident and injury.
