brake MERCEDES-BENZ CLS COUPE 2014 Owner's Guide

Always pay particular attention to the traffic
situation and be ready to brake, especially if
PRE-SAFE ®
Brake warns you. Terminate the
intervention in a non-critical driving situation.
In order to maintain the appropriate distance
to the vehicle in front and thus prevent a col-
lision, you must apply the brakes yourself. G
WARNING
PRE-SAFE ®
Brake does not react:
R to people or animals
R to oncoming vehicles
R to crossing traffic
R when cornering
As a result, PRE-SAFE ®
Brake may neither
give warnings nor intervene in all critical sit-
uations. 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, detec-
tion 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
R a narrow vehicle travelling in front, e.g. a
motorcycle
R a vehicle travelling in front on a different
line
Following damage to the front end of the vehi-
cle, have the radar sensor settings and oper- ation checked at a qualified specialist work-
shop. This also applies to collisions at slow
speeds where there is no visible damage to
the front of the vehicle. Function X
To activate/deactivate: activate or deac-
tivate PRE-SAFE ®
Brake in the on-board
computer (Y page 250).
If the PRE-SAFE ®
Brake is not activated, the
æ symbol appears in the multifunction
display.
This function will issue a warning if:
R at a speed of around 30 km/h or more the
distance maintained to the vehicle travel-
ling in front is insufficient for several sec-
onds.
The · distance warning lamp then lights
up in the instrument cluster.
R at a speed of approximately 7 km/h or
more, you rapidly approach a vehicle in
front.
An intermittent warning tone will then
sound and the ·distance warning lamp
will light up in the instrument cluster.
X Brake immediately to defuse the situation.
or X Take evasive action provided it is safe to do
so.
The PRE-SAFE ®
Brake function can also brake
the vehicle automatically under the following
conditions:
R the driver and front passenger have their
seat belts fastened
and
R the vehicle speed is between approx-
imately 7 km/h and 200 km/h
At speeds of up to approximately 70 km/h
PRE-SAFE ®
Brake can also detect stationary
objects. Examples of stationary objects are
stopped or parked vehicles.
You can prevent the intervention of PRE-
SAFE ®
Brake at any time by:
R depressing the accelerator pedal further
R activating kickdown
R releasing the brake pedal Driving safety systems
77Safety Z

The braking action of PRE-SAFE
®
Brake is
ended automatically if:
R you manoeuvre to avoid the obstacle
R there is no longer any danger of a collision
R there is no longer an obstacle detected in
front of your vehicle
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, preventive passenger protection
measures (PRE-SAFE ®
) are activated
(Y page 54). If a risk of collision remains at
speeds over 30 km/h and you do not brake,
take evasive action or significantly acceler-
ate, automatic braking may be performed up
to a level of automatic emergency braking.
Automatic emergency braking is not per-
formed until immediately prior to an accident
that can no longer be avoided. Anti-theft systems

Important safety notes
United Kingdom only: G
WARNING
When the double locks are activated, the
doors can no longer be opened from the
inside. People in the vehicle can no longer get out, e.g. in hazardous situations. There is a
risk of injury.
Therefore, do not leave any people unsuper-
vised in the vehicle, particularly children, eld-
erly people or people in need of special assis-
tance. Do not activate the double lock when
people are in the vehicle.
If the vehicle has been locked from the out-
side, the double-lock function is activated as
standard. It is then not possible to open the
doors from inside the vehicle. You can deac-
tivate the double-lock function by deactivat-
ing the interior motion sensor (Y page 79).
The doors can then be opened from the inside after the vehicle has been locked from the
outside. The anti-theft alarm system is trig-
gered if the door is opened from the inside.
Switch off the alarm (Y page 78).

WARNING
If children are left unsupervised in the vehicle, they could:
R open doors, thereby endangering other per-
sons or road users
R get out and be struck by oncoming traffic
R operate vehicle equipment and become
trapped, for example
In addition, the children could also set the
vehicle in motion, for example, if they:
R release the parking brake
R shift the automatic transmission out of park
position P or shift manual transmission into
neutral
R start the engine
There is a risk of an accident and injury.
When leaving the vehicle, always take the key with you and lock the vehicle. Never leave

Do not attach any heavy or large objects to the
key. Remove any bulky keyrings before insert-
ing the key into the ignition lock.
! Keep the key away from strong magnetic
fields. Otherwise, the remote control func-
tion could be affected.
Strong magnetic fields can occur in the

automatic reversing feature. It reacts if a solid
object obstructs or restricts the boot lid/tail-
gate during the closing procedure. The boot
lid/tailgate opens again automatically. The

R to soft, light and thin objects, e.g. small fin-
gers
R over the last 8 mm of the closing path
