2015 BMW M4 COUPE window heating

▷The engine is not yet at operating temper‐
ature.▷The wheels are at a sharp angle or the
steering wheel is being turned.▷After driving in reverse.▷Fogging of the windows when the auto‐
matic climate control is switched on.▷Vehicle battery is heavily discharged.▷At higher elevations.▷The engine compartment lid is unlocked.▷The parking assistant is activated.▷Stop-and-go traffic.▷Use of fuel with high ethanol content.
Starting the engine
The engine starts automatically under the fol‐
lowing conditions:
▷M double-clutch transmission:
By releasing the brake pedal.▷Manual transmission:
The clutch pedal is pressed.
After the engine starts, accelerate as usual.
Safety mode
After the engine switches off automatically, it
will not start again automatically if any one of
the following conditions are met.
▷The driver's safety belt is unbuckled and
the driver's door is open.▷The hood was unlocked.
Some indicator lights light up for a varied
length of time.
The engine can only be started via the Start/
Stop button.
Functional limitations
Even if driving off was not intended, the deacti‐
vated engine starts up automatically in the fol‐
lowing situations:
▷Excessive warming of the car's interior
when the cooling function is switched on.▷The steering wheel is turned.▷Double-clutch transmission: Change from
selector lever position D to N, R or D/S.▷M double-clutch transmission: Accelerat‐
ing while simultaneously applying the
brake.▷The vehicle begins rolling.▷Fogging of the windows when the auto‐
matic climate control is switched on.▷Vehicle battery is heavily discharged.▷Excessive cooling of the car's interior when
the heating is switched on.▷Low brake vacuum pressure; this can oc‐
cur, e.g., if the brake pedal is depressed a
number of times in succession.
Preventing an automatic engine stop with aM double-clutch transmission
The concept To make it possible to drive off very quickly,
such as at an intersection, the automatic en‐
gine stop can be actively prevented.
Preventing an engine stop using the
brake pedal
The engine stop can be actively prevented
within one second after the vehicle comes to a
standstill.
▷Immediately after the vehicle comes to a
standstill, briefly press the brake pedal
forcefully.▷Then press the brake pedal with normal
braking force.Seite 65DrivingControls65

HintsSufficient ventilation
When remaining in the vehicle for an ex‐
tended period of time, ensure sufficient exter‐
nal ventilation. Do not continuously use recir‐
culated-air mode; otherwise the air quality in
the interior continuously deteriorates and win‐
dow condensation increases.◀
Climate control functions in detail
Temperature Turn the ring to set the desired
temperature.
The automatic climate control reaches this
temperature as quickly as possible, if needed
by increasing the cooling or heating output,
and then keeps it constant.
Do not rapidly switch between different tem‐
perature settings. Otherwise, the automatic cli‐
mate control will not have sufficient time to ad‐
just the set temperature.
AUTO program Press button.
Air flow, air distribution and tempera‐
ture are controlled automatically.
Depending on the selected temperature,
AUTO intensity program and outside influen‐ ces, the air is directed to the windshield, side
windows, upper body, and into the footwell.
The cooling function, refer to page 135, is
switched on automatically with the AUTO pro‐
gram.
At the same time, a condensation sensor con‐
trols the program so as to prevent window
condensation as much as possible.Intensity of the AUTO program
With the AUTO program activated, the auto‐
matic intensity control can be changed.
Press the left or right side of the but‐
ton: decrease or increase the inten‐
sity.
The selected intensity is shown on the display
of the automatic climate control.
Maximum cooling Press button.
The system is set to the lowest tem‐
perature, optimum air flow and air circulation
mode.
Air flows out of the vents to the upper body re‐
gion. The vents need to be open for this.
The function is available above an external
temperature of approx. 32 ℉/0 ℃ and with the
engine running.
Adjust air flow with the program active.
Cooling function
The car's interior can only be cooled with the
engine running.
Press button.
The air will be cooled and dehumidi‐
fied and, depending on the temperature set‐ ting, warmed again.
Depending on the weather, the windshield and
side windows may fog up briefly when the en‐
gine is started.
The cooling function is switched on automati‐
cally with the AUTO program.
When using the automatic climate control,
condensation water, refer to page 158, devel‐
ops that exits underneath the vehicle.Seite 135Climate controlControls135

Switching on
Press any button except▷Rear window defroster.▷Seat heating.
Microfilter/activated-charcoal filter
In external and recirculated air mode the mi‐
crofilter/activated charcoal filter filters dust,
pollen, and gaseous pollutants out of the air.
This filter should be replaced during scheduled
maintenance, refer to page 188, of your vehi‐
cle.
Ventilation

vents continuously, arrows 2.▷Thumbwheel to vary the temperature in
the upper body region, arrow 3.
Toward blue: colder.
Toward red: warmer.
The set interior temperature for the driver
and passenger are not changed.
Adjusting the ventilation
▷Ventilation for cooling:
Direct vent in your direction when vehicle's
interior is too hot.▷Draft-free ventilation:
Adjust the vent to let the air flow past you.
Ventilation in the rear

closing of the vents, arrow 1.▷Thumbwheel to vary the temperature, ar‐

Parked-car ventilation
The concept The parked-car ventilation ventilates the vehi‐
cle interior and lowers its temperature, if
needed.
The system can be switched on and off at any
external temperature, either directly or by us‐
ing two preset reel-on times. It remains
switched on for 30 minutes.
Open the vents to allow air to flow out.

Avoid high engine speeds
As a rule: driving at low engine speeds lowers
fuel consumption and reduces wear.
Use 1st gear to get the vehicle moving. Start‐
ing with the 2nd gear, accelerate rapidly. When
accelerating, shift up before reaching high en‐
gine speeds.
When you reach the desired speed, shift into
the highest applicable gear and drive with the
engine speed as low as possible and at a con‐
stant speed.
If necessary, observe the gear shift indicator of
the vehicle, refer to page 84.
Use coasting
When approaching a red light, take your foot
off the accelerator and let the vehicle coast to
a halt.
For going downhill take your foot off the accel‐
erator and let the vehicle roll.
The flow of fuel is interrupted while coasting.
Switch off the engine during longer stops
Switch off the engine during longer stops, e.g.,
at traffic lights, railroad crossings or in traffic
congestion.
Auto Start/Stop function The Auto Start/Stop function of your vehicle
automatically switches off the engine during a
stop.
If the engine is switched off and then restarted
rather than leaving the engine running con‐
stantly, fuel consumption and emissions are
reduced. Savings can begin within a few sec‐
onds of switching off the engine.
In addition, fuel consumption is also deter‐
mined by other factors, such as driving style,road conditions, maintenance or environmental
factors.
Switch off any functions that
are not currently needed
Functions such as seat heating and the rear
window defroster require a lot of energy and
reduce the range, especially in city and stop-
and-go traffic.
Reel off these functions if they are not needed.
Have maintenance carried
out
Have vehicles maintained regularly to achieve
optimal vehicle efficiency and operating life.
The maintenance should be carried out by
your service center.
Also note the BMW Maintenance System, refer
to page 188.Seite 164Driving tipsSaving fuel164
