MERCEDES-BENZ GLC COUPE 2016 Owners Manual

!
Operating the auxiliary heating/ventilation
draws on the vehicle battery. After you have
heated or ventilated the vehicle a maximum of two times, drive for a longer distance.
Switch the auxiliary heating on regularly – once a month – for about ten minutes.
The auxiliary heating heats the air in the vehicle
interior to the set temperature. This occurs with- out using the heat of the running engine. The
auxiliary heating is operated directly using the
vehicle's fuel. For this reason, the fuel tank level
must be above the reserve range to ensure that the auxiliary heating functions.
The auxiliary heating or auxiliary ventilation
automatically adjusts to changes in tempera-
ture and weather conditions. For this reason,
the auxiliary heating could switch from ventila-
tion mode to heating mode or from heating
mode to ventilation mode.
The auxiliary heating switches off when the
engine is switched off. The auxiliary ventilation
is not active if the engine is running.
The auxiliary heating or auxiliary ventilation
switches off automatically after 50 minutes.
This time limit can be altered. To do this, consult
a qualified specialist workshop.
You cannot use the auxiliary ventilation to cool
the vehicle interior to a temperature lower than
the outside temperature.
Before switching on X
Turn the key to position 2in the ignition lock
(Y page 144).
X Set the desired temperature using the w
rocker switch on the front control unit.
If you do not alter the temperature before
switching on the auxiliary heating or auxiliary
ventilation, the last temperature setting will be
adopted.
Auxiliary heating or auxiliary ventilation can also be switched on if the manually set climate con-
trol is activated. Optimum comfort is attained
when the system is set to automatic mode. Set
the temperature to 22 †.
You can switch the auxiliary heating or auxiliary
ventilation on or off:
R using the rocker switch on the centre console
(Y page 138)
R using the remote control (Y page 139)The remote control can be used to set up to
three departure times, one of which may be pre- selected.

General notes
Your vehicle comes with one remote control.
You may use two additional remote controls for
your vehicle. For more information, please con-
tact a qualified specialist workshop.
Store the remote control for the auxiliary heat-
ing so that the auxiliary heating cannot be
switched on unintentionally. In particular,

heating is kept out of the reach of children.
The remote control has a range of approximately
300 metres. This range is reduced by:
R sources of radio interference
R solid objects between the remote control and
the vehicle
R the remote control being in an unfavourable
position in relation to the vehicle
R transmitting from an enclosed space
If the remote control battery is low, the battery
symbol on the left of the display is shown as

Running-in notes
Important safety notes
In certain driving and driving safety systems, the sensors adjust automatically while a certain dis-
tance is being driven after the vehicle has been delivered or after repairs. Full system effective-
ness is not reached until the end of this teach-in process.
Brake pads/linings and discs that either are new or have been replaced achieve optimum braking
effect only after several hundred kilometres of
driving. Compensate for the reduced braking
effect by applying greater force to the brake
pedal. The first 1500 km
The more you treat the engine with sufficient
care at the start, the more satisfied you will be
with the engine performance later on.
R You should therefore drive at varying road
speeds and engine speeds for the first
1500 km.
R Avoid overstraining the vehicle during this
period, e.g. driving at full throttle.
R When shifting gears manually, shift up in good
time, before the rev counter needle reaches
Ô of the way to the red area of the rev counter
display.
R Do not shift down a gear manually in order to
brake.
R Try to avoid depressing the accelerator pedal
beyond the pressure point (kickdown).
After 1500 km, you can increase the engine
speed gradually and accelerate the vehicle to
full speed.
You should also observe these notes on running- in if the engine or parts of the drive train on your
vehicle have been replaced.
Always observe the maximum permissible
speed. Driving
Important safety notes
G
WARNING
Objects in the driver's footwell can impede
pedal travel or block a pedal which is
depressed. This jeopardises safe operation of the vehicle. There is a risk of an accident.
Stow all objects in the vehicle safely, so that
they cannot reach the driver's footwell. Make sure the floormats and carpets are properly
secured so that they cannot slip and obstruct the pedals. Do not lay several floormats or
carpets on top of one another. G
WARNING
Unsuitable footwear can hinder correct usage of the pedals, e.g.:
R shoes with thick soles
R shoes with high heels
R slippers
There is a risk of an accident.
Wear suitable footwear to ensure correct
usage of the pedals. G
WARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect, for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk of an accident.
Do not switch off the ignition while driving. G
WARNING
If the parking brake has not been fully
released when driving, the parking brake can:
R overheat and cause a fire
R lose its hold function.

positions in the ignition lock. This is the case
only if you are not depressing the brake pedal. If you depress the brake pedal and press the
Start/Stop button, the engine starts immedi-
ately.
A check that periodically establishes a radio
connection between the vehicle and the key
determines whether a valid key is in the vehicle.
This occurs, for example, when the engine is
started.
To start the vehicle without actively using the
key:
R the Start/Stop button must be inserted in the
ignition lock
R the key must be in the vehicle
R the vehicle must not be locked with the key or

Do not keep the key:
R with electronic devices, e.g. a mobile phone
or another key
R with metallic objects, e.g. coins or metal foil
R inside metallic objects, e.g. a metal case
This can impair the key's function.
If you lock the vehicle with the key's remote
control or with KEYLESS-GO, after a short time:
R you will no longer be able to switch on the
ignition with the Start/Stop button
R you will no longer be able to start the engine
with the Start/Stop button until the vehicle is

away. 146
DrivingDriving and parking

The vehicle automatically locks centrally once
you have pulled away. The locking knobs in the
doors drop down.
You can open the doors from the inside at any
time.
You can also deactivate the automatic door
locking system; see the Digital Owner's Manual.
It is possible to shift the transmission from posi-
tion jto the desired position only if you
depress the brake pedal. Only then is the park-
ing lock released. If you do not depress the
brake pedal, the DIRECT SELECT lever can still
be moved but the parking lock remains
engaged.
i Upshifts take place at higher engine speeds
after a cold start. This helps the catalytic con-
verter to reach its operating temperature
more quickly.

Hill start assist Hill start assist helps you when pulling away for-
wards 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
depress it before the vehicle begins to roll. G
WARNING
After a while, hill start assist no longer holds
the vehicle and it may 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.
