If the driver and front passenger have their
seat
belt fastened, PRE-SAFE ®
Brake can also
brake the vehicle automatically at speeds
from approximately 4 mph (7 km/h) 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 of up to 40 mph (70 km/h), PRE-
SAFE ®
Brake can also detect stationary
obstacles, for example, 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, preventive passenger protection
measures (PRE-SAFE ®
) are activated
(Y page 54). If, at speeds over 20 mph
(30 km/h), a risk of collision remains and you
do not brake, take evasive action or
significantly accelerate, automatic braking
may be performed up to the level of
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 emergency braking cannot prevent
a collision. There is a risk of an accident.
Always apply the brakes yourself and try to
take evasive action. G
WARNING
PRE-SAFE ®
Brake cannot always clearly
identify objects and complex traffic
conditions.
In these cases, PRE-SAFE ®
Brake may:
R give an unnecessary warning and then
brake the vehicle
R not give a warning or intervene
There is a risk of an accident.
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 particular, the detection of obstacles can
be impaired if there is:
R dirt on the sensors or anything else
covering the sensors
R snow or heavy rain
R interference by other radar sources
R the possibility of strong radar reflections,
for example in parking garages
R a narrow vehicle traveling in front, e.g. a
motorbike
R a vehicle traveling in front on a different line
relative to the center of your vehicle G
WARNING
PRE-SAFE ®
Brake does not react:
R to people or animals
R to oncoming vehicles Driving safety systems

Safety
Z
R
to crossing traffic
R when cornering
As a result, PRE-SAFE ®
Brake may neither
give warnings nor intervene in all critical
situations. There is a risk of an accident.
Always pay careful attention to the traffic
situation and be ready to brake.
In
order to maintain the appropriate distance
to the vehicle in front and thus prevent a
collision, you must apply the brakes yourself.
X To activate/deactivate: activate or
deactivate PRE-SAFE ®
Brake in the on-
board computer ( Y page 237).
When PRE-SAFE ®
Brake is activated, the
Ä symbol appears in the multifunction
display, as long as the HOLD function is
deactivated (Y
page 196). On vehicles with
the Active Parking Assist driving system,
the Ä symbol is displayed when position
P is engaged or you are driving faster than
22 mph (35 km/h).
For PRE-SAFE ®
Brake to assist you when
driving, the radar sensor system must be
switched on (Y page 241) and be
operational.
Following damage to the front end of the
vehicle,
have the configuration and operation
of the radar sensors checked at a qualified
specialist workshop. This also applies to
collisions at low speeds where there is no
visible damage to the front of the vehicle.

Important safety notes
New and replaced brake pads and discs only
reach their optimum braking effect after
several hundred kilometers of driving.
Compensate
for this by applying greater force
to the brake pedal. The first 1,000 miles (1,500 km)
The
more you look after the engine when it is
new, the more satisfied you will be with its
performance in the future.
R You should therefore drive at varying
vehicle and engine speeds for the first
1,000 miles (1,500 km).
R Avoid heavy loads, e.g. driving at full
throttle, during this period.
R Change gear in good time, before the
tachometer needle is Ô of the way to the
red area of the tachometer.
R If possible, do not depress the accelerator
pedal past the point of resistance
(kickdown).
R Only select shift ranges 3, 2 or 1 when
driving slowly, e.g. in mountainous terrain.
After 1,000 miles (1,500 km), you can
increase the engine speed gradually and
accelerate the vehicle to full speed. Additional breaking-in notes for AMG
vehicles:
R
Do not drive faster than
85 mph
(140 km/h) for the first 1000 miles
(1500 km).
R Only allow the engine to reach a maximum
engine speed of 4500 rpm briefly.
R Change gear in good time.
i You should also observe these notes on
running in if the engine or parts of the drive
train on your vehicle have been replaced.
i Always observe the respective speed
limits. AMG vehicles with rear axle locking
differential
Your vehicle is equipped with a self-locking
differential on the rear axle. To improve the
protection
of the differential on the rear axle,
change the oil after a break-in distance of
2,000 miles (3,000 km). This oil change
extends the service life of the differential.
Have the oil change carried out at a qualified
specialist workshop. Driving
