2016 BMW M4 CONVERTIBLE Top control

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 137, 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.
Convertible program
When the hardtop is open, the convertible pro‐
gram is activated as well. In the convertible
program, the automatic climate control is opti‐
mized for driving with the hardtop open. In ad‐
dition, the air flow is increased as the vehicle
speed increases.
The efficiency of the convertible program can
be greatly enhanced by installing the wind de‐
flector.
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.

BMW M4 technologyVehicle features and options
This chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and
systems. The respectively applicable country
provisions must be observed when using the
respective features and systems.
High-performance engine The high-performance engine gets a maximum
power of 317 kW and maximum torque of
550 Nm from a displacement of 3 liters. With
its spontaneous response behavior, a speed
range of wide utility results. The maximum en‐
gine speed is 7,600 rpm and is electronically
controlled. Because of the high engine dynam‐
ics, the maximum engine speed with the vehi‐
cle stationary is reduced.
Warm-up During the engine warm-up phase, the high-performance engine has a somewhat rougher
running behavior because of the emission con‐
trols.
When the engine is cold, the exhaust system
has a slightly metallic undertone due to the na‐
ture of the system.
For more information about the warm-up pro‐
cedure: Engine speed, refer to page 81, and
engine oil temperature, refer to page 81.
Compound brake
The high-performance braking system has
perforated compound brake discs.Because of particular structural characteristics,
there may be operation-related noises during
braking. However, this has no effect on per‐
formance, operational reliability and reliability
of the brake.
Correct brakingTo keep the brake system in optimum condi‐
tion, it is expedient to apply them at regular in‐
tervals corresponding to the vehicle character.
M carbon ceramic brake The high-performance braking system has
perforated carbon-ceramic brake disks and is
designed for use on racetracks.
Due to properties of the materials used, brak‐ ing may be associated with louder function
noises, particularly in wet conditions, just be‐
fore the vehicle comes to a stop. However, this
has no effect on the performance, operational
reliability and durability of the brake.
The effects of moisture and road salt, from us‐
ing a carwash or dew formation overnight e.g.,
may render the braking effect comparable to
that of a conventional braking system. This
may be perceived as reduced braking effect
and can be compensated for if needed by
pressing the brake pedal harder.
Before washing the vehicle in an automatic
carwash or wash tunnel, clean the brake discs
and brake calipers with a steam jet or high-
pressure washer as well, to prevent encrusta‐
tions and dirt buildups, caused by salt crystals,
e.g., if the car is immobile afterwards. The
cleaning effect of automatic carwashes or
wash tunnels is usually not adequate for this in
the area around the wheels.
To do this, also follow the instructions in
Washing the vehicle, refer to page 204, and
Braking safely, refer to page 159.Seite 156Driving tipsBMW M4 technology156

Objects within the range of movement
of the pedals
No objects in the area around the pedals
Keep floor mats, carpets, and any other
objects out of the pedal area; otherwise, the
function of the pedals could be impeded while
driving and create the risk of an accident.
Do not place additional floor mats over existing
mats or other objects.
Only use floor mats that have been approved
for the vehicle and can be properly attached to
floor.
Ensure that the floor mats are securely fas‐
tened again after they were removed for clean‐
ing, e.g.◀
Driving in wet conditions When roads are wet, salted, or in heavy rain,
press brake pedal ever so gently every few
miles.
Ensure that this action does not endanger other traffic.
The heat generated in this process helps dry
the brake discs and pads.
In this way braking efficiency will be available
when you need it.
Hills Avoid stressing the brakes
Avoid placing excessive stress on the
brake system. Light but consistent brake pres‐
sure can lead to high temperatures, brakes
wearing out and possibly even brake failure.◀
Do not drive in neutral
Do not drive in neutral or with the engine
stopped, as doing so disables engine braking.
In addition, steering and brake assist are un‐
available with the engine stopped.◀
Drive long or steep downhill gradients in the
gear that requires least braking efforts. Other‐wise the brakes may overheat and reduce
brake efficiency.
Manual transmission:
You can increase the engine's braking effect
by shifting down, going all the way to first gear,
if needed.
M double-clutch transmission:
You can increase the engine's braking effect
by shifting down in sequential mode, refer to
page 72.
Brake disc corrosion
Brake disc corrosion and contamination of the
brake pads are favored by:▷Low mileage.▷Extended periods when the vehicle is not
used at all.▷Infrequent use of the brakes.
Corrosion will built up when the maximum
pressure applied to the brake pads during
braking is not reached - thus discs don't get
cleaned.
Corrosion buildup on the brake discs will cause
a pulsating effect on the brakes in their re‐
sponse - generally that cannot be corrected.
Condensation under the parked
vehicle
When using the automatic climate control,
condensation water develops collecting under‐
neath the vehicle.
These traces of water under the vehicle are
normal.
Ground clearance Limited ground clearance
Observe the limited ground clearance of
the vehicle, e. g. while entering underground
parking garages or when driving over obsta‐
cles. Otherwise, damages to the vehicle may
result.◀

Recommendation
Regardless of wear and tear, replace tires at
least every 6 years.
Uniform Tire Quality Grading Quality grades can be found where applicable
on the tire sidewall between tread shoulder
and maximum section width.
For example: Treadwear 200; Traction AA;
Temperature ADOT Quality Grades
Treadwear
Traction AA A B C
Temperature A B C
All passenger car tires must conform to Fed‐
eral Safety Requirements in addition to these
grades.
Treadwear The treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov‐
ernment test course. For example, a tire
graded 150 would wear one and one-half, 1 g,
times as well on the government course as a
tire graded 100. The relative performance of
tires depends upon the actual conditions of
their use, however, and may depart signifi‐
cantly from the norm due to variations in driv‐
ing habits, service practices and differences in
road characteristics and climate.
Traction
The traction grades, from highest to lowest,
are AA, A, B, and C.
Those grades represent the tire's ability to
stop on wet pavement as measured under
controlled conditions on specified government
test surfaces of asphalt and concrete. A tire
marked C may have poor traction performance.
The traction grade assigned to this tire is
based on straight-ahead braking traction tests,
and does not include acceleration, cornering,
hydroplaning, or peak traction characteristics.
Temperature The temperature grades are A, the highest, B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate
heat when tested under controlled conditions
on a specified indoor laboratory test wheel.
Sustained high temperature can cause the ma‐
terial of the tire to degenerate and reduce tire
life, and excessive temperature can lead toSeite 174MobilityWheels and tires174

spray the seals of the lowerable hardtop, sen‐
sors and cameras external to the vehicle, e.g.,Park Distance Control, for extended periods of
time and only from a distance of at least
12 in/30 cm.◀
Automatic car washes
Hints Do not use high pressure washing sys‐
tems
With washing systems operating at high pres‐
sures and nozzle positions close to the win‐
dows, drops of water can penetrate.◀▷Give preference to cloth car washes or
those that use soft brushes in order to
avoid paint damage.▷Make sure that the wheels and tires are not
damaged by the transport mechanisms.▷Fold in the exterior mirrors; otherwise, they
may be damaged, depending on the width
of the vehicle.▷Deactivate the rain sensor, refer to
page 69, to avoid unintentional wiper acti‐
vation.▷In some cases, an unintentional alarm can
be triggered by the interior motion sensor
