2018 MERCEDES-BENZ GLC adjust brake pedal

PRE-SAFE ®
takes the following measures
depending on the hazardous situation detected: R
the front seat belts are pre-tensioned. R
if the vehicle skids, the side windows and the
panorama roof with power tilt/sliding panel
are closed. R
vehicles with the memory function for the
front-passenger seat: the front-passenger
seat is adjusted if it is in an unfavorable posi-
tion.
If the hazardous situation passes without result-
ing in an accident, PRE-SAFE ®
slackens the belt
pre-tensioning. All settings made by PRE-SAFE ®
can then be reversed.
If the seat belt pre-tensioning is not reduced: X
Move the seat backrest or seat back slightly
when the vehicle is stationary.
The seat belt pre-tensioning is reduced and
the locking mechanism is released.
The seat-belt adjustment is an integral part of
the PRE-SAFE ®
convenience function. Informa-
tion about the convenience function can be
found under "Belt adjustment" ( Y
page 48).
PRE-SAFE ®
PLUS (anticipatory occu-
pant protection system PLUS)
Introduction PRE-SAFE ®
PLUS is only available in vehicles
with the Driving Assistance package.
Using the radar sensor system, PRE-SAFE ®
PLUS is able to detect that a head-on or rear-end
collision is imminent. In certain hazardous sit-
uations, PRE-SAFE ®
PLUS takes pre-emptive
measures to protect the vehicle occupants.
Important safety notes The intervention of PRE-SAFE ®
PLUS cannot
prevent an imminent collision.
The driver is not warned about the intervention
of PRE-SAFE ®
PLUS.
PRE-SAFE ®
PLUS does not intervene:R
if the vehicle is backing up R
when the vehicle is towing a trailer and there
is a risk of a rear-end collision When driving, or when parking or exiting a park-
ing space with assistance from Parking Pilot,
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 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-
celed: 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 are implemented, depending on the
type and severity of the impact: R
the hazard warning lamps are switched on R
the emergency lighting is activated R
the vehicle doors are unlocked R
the front side windows are lowered R
vehicles with a memory function: the electri-
cally adjustable steering wheel is raised when
the driver's door is opened R
the engine is switched off and the fuel supply
is cut off R

Notes on breaking-in a new vehicle
Important safety notes The sensor system of some driving and driving
safety systems adjusts automatically while a
certain distance is being driven after the vehicle
has been delivered or after repairs. Full system
effectiveness is not reached until the end of this
teach-in procedure.
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 per-
formance 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
When changing gears manually, change up in
good time, before the tachometer needle rea-
ches

RACE START
Important safety notes
i RACE START is only available for the
Mercedes-AMG GLC 63 4MATIC+ and
Mercedes-AMG GLC 63 S 4MATIC+ models.
i RACE START must not be used on normal
roads. RACE START must only be activated and used on dedicated road circuits, outside
of public road use.
i RACE START is only available after the vehi-
cle has been run-in ( Y
page 135).
RACE START enables optimal acceleration from
a standing start. For this, a suitably high-grip
road surface is required and the vehicle and tires
must be in good working order.
G WARNING
If you use RACE START, individual tires may
start to spin and the vehicle could skid.
Depending on the selected ESP ®
mode, there
is an increased risk of skidding and having an
accident. Make sure that no persons, animals
or obstacles are within range of the vehicle.
i Observe the safety notes on driving safety
systems ( Y
page 66).
Be sure to read the safety notes and informa-
tion on ESP ®
( Y
page 69).
Activation conditions You can activate RACE START if: R

RACE START is deactivated immediately if you
release the accelerator pedal during RACE
START or if any of the activation conditions are
no longer fulfilled. The RACE START Canceled
message appears in the multifunction display.
i If RACE START is used repeatedly within a
short period of time, it is only available again
after the vehicle has been driven a certain
distance.
AIR BODY CONTROL
General notes AIR BODY CONTROL is an air suspension system
with variable damping for improved driving com-
fort. All-round level control ensures the best
possible suspension and constant ground clear-
ance, even with a laden vehicle. When you drive
fast, the vehicle is lowered automatically to
improve driving safety and to reduce fuel con-
sumption. There is also the option to manually
adjust the vehicle level.
AIR BODY CONTROL consists of: R
air suspension system with variable spring
rate R
automatic level control R
speed-dependent lowering to reduce fuel
consumption R
manual level control R
