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

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

the Parking Pilot Finished message
appears and a warning tone sounds. The vehicle
is now parked.
The vehicle is kept stationary without the driver
having to depress the brake pedal. The braking
effect is canceled when you depress the accel-
erator pedal.
Parking Pilot no longer supports you with steer-
ing interventions and brake applications. When
Parking Pilot is finished, you must steer and
brake again yourself. Parking Assist
PARKTRONIC is still available.
Parking tips: R
The way your vehicle is positioned in the park-
ing space after parking is dependent on vari-
ous factors. These include the position and
shape of the vehicles parked in front and
behind it and the conditions of the location. It
may be the case that Parking Pilot guides you
too far into a parking space, or not far enough
into it. In some cases, it may also lead you
across or onto the curb. Cancel the parking
procedure with Parking Pilot if necessary. R
You can also prematurely select transmission
position [ . The vehicle redirects and does
not drive as far into the parking space. Should
the transmission change take place too early,
the parking procedure is canceled. A sensible
parking position can no longer be achieved
from this position.
Exiting a parking space In order for Parking Pilot to support you when
exiting the parking space: R
the border of the parking space must be high
enough at the front and the rear. A curb stone
is too small, for example. R
the border of the parking space must not be
too wide. Your vehicle can be maneuvered
into the parking space at a maximum angle of
45° to the starting position. R
a maneuvering distance of at least 3.3 ft
(1.0 m) must be available.
Parking Pilot can assist you with exiting a park-
ing space only if you have parked the vehicle
parallel to the direction of travel using Parking
Pilot.
i If Parking Assist PARKTRONIC detects
obstacles, Parking Pilot brakes automatically190

which the maximum permissible speed for vehi-
cle/trailer combinations is above 60 mph
(100 km/h).
When towing a trailer, your vehicle's handling
characteristics will be different in comparison to
when driving without a trailer and it will con-
sume more fuel.
Shift to a lower gear on long and steep downhill
gradients.
This also applies to: R
activated DISTRONIC PLUS R
activated cruise control
This will use the braking effect of the engine, so
that less braking will be required to maintain the
speed. This relieves the load on the brake sys-
tem and prevents the brakes from overheating
and wearing too quickly. If you need additional
braking, depress the brake pedal repeatedly
rather than continuously.
Driving tips If the trailer swings from side to side: X
Do not accelerate. X
Do not counter-steer. X
Brake if necessary. R
Maintain a greater distance from the vehicle
in front than when driving without a trailer. R
Avoid braking abruptly. If possible, brake gen-
tly at first to allow the trailer to run on. Then,
increase the braking force rapidly. R
The values given for gradient-climbing capa-
bilities from a standstill refer to sea level.
When driving in mountainous areas, note that
the power output of the engine and, conse-
quently, the vehicle's gradient-climbing capa-
bility, decreases with increasing altitude.
Installing the ball coupling
G WARNING
If the ball coupling is not correctly installed
and secured, it could come loose while driving
and endanger other road users. There is a risk
of an accident and injury.
Install and secure the ball coupling as descri-
bed in the ball coupling manufacturer's instal-
lation instructions. Make sure that the ball coupling is correctly installed and secured
before every journey.
G WARNING
If the ball coupling is not installed and secured
correctly the trailer may come loose. There is
a risk of an accident.
Install and secure the ball coupling as descri-
bed in the ball coupling installation instruc-
tions. Make sure that the ball coupling is
installed and secured correctly before every
journey.
X
Pull protective cap C in the direction of the
arrow, out of the ball coupling recess. X
Stow protective cap C so that it cannot be
thrown around. X
Observe the manufacturer's installation
instructions.

page 290)
and the safety notes regarding stowage
spaces ( Y
page 290).
Coupling up a trailer
! Do not connect the trailer's brake system (if
featured) to the hydraulic brake system of the
towing vehicle, as the latter is equipped with
an anti-lock brake system. Doing so will result
in a loss of function of the brake systems of
both the vehicle and the trailer. X
