Pulling away with a trailer
To ensure that you do not roll backwards when
pulling away on an uphill slope, engage the elec-
tric parking brake. X
Press and hold handle C .
The electric parking brake continues to brake
and prevent the vehicle from rolling back-
wards.
The red I (USA only) or $ (Canada
only) indicator lamp in the instrument cluster
remains on. X
Depress the accelerator pedal. X
As soon as the vehicle/trailer combination is
held by the driving force of the engine, release
lever C .
The electric parking brake is released.
The red I (USA only) or $ (Canada
only) indicator lamp in the instrument cluster
goes out.
For further information on the electric parking
brake, see ( Y
page 159).
Hill start assist
Hill start assist helps you when pulling away
forward 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 to
depress it before the vehicle begins to roll.
G WARNING
After a short time, hill start assist will no lon-
ger brake your vehicle and it could 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 on a
downhill gradient. R
the transmission is in position \\R
the electric parking brake is applied. R
ESP ®
is malfunctioning
ECO start/stop function
Introduction The ECO start/stop function switches the
engine off automatically if the vehicle is stopped
under certain conditions.
The engine starts automatically when the driver
wants to pull away again. 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.
If you wish to exit the vehicle, always turn off
the ignition and secure the vehicle against
rolling away.140

Turn the SmartKey back to position

Problem
Possible causes/consequences and P Solutions
The engine is not running
smoothly and is misfir-
ing. There is a malfunction in the engine electronics or in a mechanical
component of the engine management system. X
Only depress the accelerator pedal slightly.
Otherwise, non-combusted fuel may get into the catalytic converter
and damage it. X
Have the cause rectified immediately at a qualified specialist work-
shop.
The coolant temperature
display indicates a value
within the red band. The coolant level is too low. The coolant is too hot and the engine is no
longer being cooled sufficiently. X
Stop as soon as possible and allow the engine and the coolant to
cool down. X
Check the coolant level ( Y
page 322). Observe the warning notes
as you do so and add coolant if necessary.

Important safety notes
G WARNING
If the engine speed is above the idling speed
and you engage transmission position D or R ,
the vehicle could pull away suddenly. There is
a risk of an accident.
When engaging transmission position D or R ,
always firmly depress the brake pedal and do
not simultaneously accelerate.
G WARNING
The automatic transmission switches to neu-
tral position N when you switch off the engine. The vehicle may roll away. There is a risk of an
accident.
After switching off the engine, always switch
to parking position P . Prevent the parked vehi-
cle from rolling away by applying the parking
brake.
Hybrid vehicles: be sure to observe the notes
in the supplement. Otherwise, you may not rec-
ognize dangers.

are available.
Driving tips
Changing gear The automatic transmission shifts through the
individual gears automatically when it is in trans-
mission position [ . This automatic gear shift-
ing behavior is determined by: R
the selected drive program R
the position of the accelerator pedal R
the road speed
Accelerator pedal position Your style of driving influences how the auto-
matic transmission shifts gear: R
little throttle: early upshifts R
more throttle: late upshifts
Double-clutch function
When shifting down, the double-clutch function
is active regardless of the currently selected
drive program. The double-clutch function reduces load change reactions and is conducive
to a sporty driving style. The sound generated by
the double-clutch function depends on the drive
program selected.
Kickdown Use kickdown for maximum acceleration. X
Depress the accelerator pedal beyond the
pressure point.
The automatic transmission shifts to a lower
gear depending on the engine speed. X
Ease off the accelerator pedal once the
desired speed is reached.
The automatic transmission shifts back up.
Gliding mode
Gliding mode is available depending on the
equipment.
Gliding mode is characterized by the following: R
The combustion engine is disconnected from
the drive train. R
The engine speed corresponds to the idling
speed. R
The multifunction display hides the gear indi-
cator and displays transmission position [
in green ( Y

In drive program E or in drive program C
(Mercedes-AMG GLC 63 4MATIC/
GLC 63 S 4MATIC) you can deactivate and acti-
vate gliding mode using the ECO button
( Y
page 142).
Gliding mode can be activated under the follow-
ing conditions: R
The speed is within a suitable range. R
The course of the road is suitable, e.g. there
are no steep up or downhill gradients. R
You are no longer depressing the accelerator
pedal.Automatic transmission 149
