2021 BMW M4 Owners Manual

Safety
note
NOTE
Driving
through
excessively
deep
water
too
fast
can
result
in
water
entering
the
engine
comj partment,
electrical
system
or
transmission.
There
is
a
risk
of
material
damage.
When
drivj
ing
through
water,
do
not
exceed
the
maximum water
depth
and
speed
specified
above.
Safe
braking
GeneralThe
vehicle
is
equipped
with
an
Anti-lock
Brake
System
ABS
as
standard.
Perform
full
braking
in
situations
that
require
it.
The
vehicle
remains
steerable.
Any
obstacles
can
be
avoided
by
steering
as
smoothly
as
possij
ble.
A
pulsing
of
the
brake
pedal
shows
that
the
Anti- lock
Brake
System
ABS
is
regulating.
In
certain
braking
situations,
the
perforated
brake
discs
can
cause
functional
noise.
However,
the functional
noises
have
no
effect
on
the
efficiencyand
operational
safety
of
the
brakes.
Objects
in
the
range
of
movement
of
the
pedals
WARNING
Objects
in
the
driver's
footwell
can
restrict
the pedal
travel
or
block
a
pedal
that
has
been
pressed.
There
is
a
risk
of
accident.
Ensure
that
items
in
the
vehicle
are
stowed
securely
and
cannot
get
into
the
driver's
footwell.
Only
use floor
mats
that
are
suitable
for
the
vehicle
and
can
be
securely
fastened
to
the
floor.
Do
not
use
loose
floor
mats,
and
do
not
place
several
floor
mats
on
top
of
one
another.
Make
sure
that
there
is
sufficient
space
for
the
pedals.
Enj
sure
that
floor
mats
are
securely
reattached
afj
ter
removal,
for
example
for
cleaning.
Pedal
feel
when
driving
off When
the
drive-ready
state
has
been
switched
on
after
the
rest
state,
an
unfamiliar
pedal
feel can
occur,
for
example
short
pedal
travel.
Onceyou
have
completely
released
the
brake
pedal,the
pedal
feel
will
be
back
to
normal.
Wet
roads
In
wet
weather,
on
gritted
roads
and
in
heavy
rain,
apply
the
brakes
lightly
every
few
kilomej
tres/miles.
Ensure
that
you
do
not
obstruct
other
road
users
when
doing
so.
The
heat
generated
by
braking
dries
the
brake
discs
and
brake
pads
and
protects
them
against corrosion.
This
helps
to
maintain
the
brake
power
so
that
it
is
available
immediately
when
needed.
Downhill
gradients General
When
driving
on
long
or
steep
downhill
stretches,
use
the
gear
in
which
the
least
braking is
required.
Otherwise
the
brake
system
canoverheat
and
the
braking
effect
is
reduced.
Engine
braking
effect
can
be
additionally
inj
creased
by
manually
shifting
down,
even
into
first gear,
if
applicable.
Safety
notes
WARNING
Even
slight
but
continuous
pressure
on
the
brake
pedal
can
cause
overheating,
brake
pad wear
or
even
brake
system
failure.
There
is
a
risk
of
accident.
Avoid
excessive
loads
on
the
brake.

Reducing
fuel
consumption
General
The
vehicle
possesses
wide-ranging
technoloj
gies
for
reducing
consumption
and
emission
levj
els.
Fuel
consumption
depends
on
various
factors.
A
number
of
measures,
such
as
a
moderate
drivj ing
style
and
regular
maintenance,
can
influencefuel
consumption
and
reduce
the
burden
on
the
environment.
Remove
unnecessary
loadsExtra
weight
increases
fuel
consumption.
Remove
mounted
parts
after
use Remove
unneeded
roof
racks
after
use.Add-on
accessories
on
the
vehicle
can
adverselyaffect
its
aerodynamic
performance
and
increase
fuel
consumption.
Close
windows
and
the
glass
sunroof
An
open
glass
sunroof
or
open
window
increasedrag
and
consequently
fuel
consumption.
Tyres
GeneralTyres
can
have
differing
effects
on
consumption
figures.
Consumption
can
be
affected
by
the
size of
the
tyres,
for
example.
Check
tyre
inflation
pressure
regularly
Check
and,
if
necessary,
correct
the
tyre
inflationpressures
at
least
twice
a
month
and
before
setj
ting
off
on
a
longer
journey.
Insufficient
tyre
inflation
pressure
enlarges
the
rolling
resistance
and
thus
increases
fuel
conj sumption
and
tyre
wear.
For
further
information:
Tyre
inflation
pressure
information,
see
page
336.
Drive
off
immediately Do
not
warm
up
the
engine
with
the
vehicle
at
astandstill,
but
instead
set
off
straight
away,
drivj
ing
at
moderate
engine
speeds.
This
brings
the
cold
engine
up
to
operating
temj perature
as
quickly
as
possible.
Think
ahead
Anticipating
the
road
situation
and
adopting
a
smooth
driving
style
will
reduce
fuel
consumpj tion.
Avoid
accelerating
and
braking
unnecessarily. Keep
an
appropriate
distance
from
the
vehicleahead.
Avoid
high
engine
speeds
Driving
at
low
engine
speeds
reduces
fuel
conj
sumption
and
